# v 1.1.8 2015-12-18 [stable]
This is an emergency bug-fixing release.
It addresses systematic crashes on some platforms, right at startup time,
and prevents random deadlocks on OS/X.
The systematic crash was due to an innocent change, which actually perturbed
the order of the initialization routines and, depending on the conditions,
caused an assertion failure during one of the thread startup. Curiously, the
error manifests randomly and does not seem to depend on the OS but rather on
other subtle environment issues: one Linux distribution could be fine whilst
another was hit by the bug.
# v 1.1.7 2015-12-13 [stable]
This release adds support for new features:
- TLS upgrade of existing connections.
- Inbound HTTPS connections
- Use of a supervisor process to relaunch gtk-gnutella on crashes
The TLS upgrade allows connections that have started without TLS to negotiate
TLS on the fly without having to reconnect. They are flagged as "e" to show
that encryption was dynamically added, as opposed to "E" which indicates an
initial TLS connection.
Certificates are now automatically generated and this allows HTTPS connections
from browsers. For now this is of limited use, but it will come handy in the
near future when building a web-enabled GUI.
To be more resilient against crashes, gtk-gnutella now automatically launches
a supervisor process that will launch the real gtk-gnutella as a child process
and monitor its fate, restarting a new process when the old one failed. This
is far more robust than having the process re-exec() itself at crash time since
there are some crashing conditions that do not even allow the process to go
that far in the crash handling...
On Windows, provided you have installed Cygwin's gdb, crash logs will now
contain a gdb backtrace of the failing process, making analysis of what went
wrong easier than with a simple stack trace.
Your previous GUID and KUID will be regenerated the next time you restart due
to a new algorithm used to detect that a configuration file is not accidentally
reused on another machine: the host name is now included, instead of just the
physical file information. So when moving a disk to another machine, or simply
cloning an existing virtual machine, we are no longer going to reuse these
IDs which are supposed to be unique by properly detecting that the information
was copied over.
A bug in open_read() caused the Geo IP database to not be loaded on Windows.
Finally, all the options given to gtk-gnutella can now be abbreviated as long
as they are not ambiguous (i.e. enough is given to make them non-ambiguous).
For instance, given the current set of options, --p would be ambiguous but --s
will always mean --shell. However, --pi is not ambiguous and refers to --ping.
Improvements:
- By default, gtk-gnutella now supervises its children to restart them.
- Now allows incoming HTTPS connections.
- Added support for Gnutella connection upgrade to TLS.
- Added support of RFC-2817 for upgrading to TLS within HTTP/1.1.
- Dump symbolic stack when crashing in supervised mode with our parent.
- VMM: added new flag to signal OOM condition and be aggressive with the cache.
- Options can now be abbreviated as long as they are not ambiguous.
- Added support for Virtual Memory Emergency Allocation (VMEA).
- Pulled latest translations from Transifex.
Bug Fixes:
- Make sure node_by_guid() cannot return a G2 node!
- VMM: fixed memory allocation logic during crashes.
- open_read(): fixed logic on Windows when no renaming is requested.
- Make sure we don't restart nor pause a failing process on --shell or --ping.
Under the Hood:

# v 1.1.5 2015-10-08 [stable]
This is a bug-fixing release.
Most of these bugs were discovered by investigating why gtk-gnutella was
frequently crashing on OS/X platforms. Why other platforms were not having
the same problems remains a mystery, since all these bugs were not specific
to OS/X, apart from the vmm_munmap() bug -- since mmap() is only used on
OS/X due to its lack of the sendfile() system call.
One of the fixed bugs could lead to a crash when the network connection was
broken (e.g. a cable unplugged or a WiFi connection terminated).
Improvements:
- UHC: re-engineered the random choice of UHCs in the pre-established list.
Bug Fixes:
- qrt_patch_compress_done(): fixed race with qrp_comp_done().
- xmalloc: prevent deadlock when freeing deferred blocks on the allocation path.
- pmap_remove_from(): protect from exceptional corner case to avoid crash.
- ut_frag_pmsg_free(): don't requeue an unsent message synchronously.
- VMM: fixed race condition in vmm_munmap() that could lead to failures.
- omalloc: fixed chunk management when memory alignment is required.
Under the Hood:
- well_state_discard(): fixed missing indexing of array pointer.
- thread-test: avoid mixed output by using atomic I/Os to stderr for messages.
- thread-test: main testing entry points now clearly flagged in output.
- signal_trampoline(): be verbose and lenient when our pre-condition fails.
- evq_event_discard(): fixed message to log the name of the registering thread.
- hash_list_lookup(): was mistakenly returning a const value.
- thread_private_set_extended(): ensure a NULL free routine clears any old one.
- crash_mode(): removed redundant call to thread_suspend_others().
- rand31_random_seed(): avoid popcount(), prefer modulo with a prime number.
- hash_offset_init_once(): avoid entropy_minirand(), causes dealocks on Windows.
- uhc_send_ping(): if we cannot contact selected UHC, try with another one.
- omalloc_chunk_*protect(): ensure chunk is consistent with page boundaries.
- More assertions in omalloc() to ensure we're not corrupting memory.
- Use global mutex to protect symbols_xxx() calls, simplified stacktrace code.
- Reduced UHC retry time from 1 hour down to 3 minutes.
- Revised UHC list.
- More thread-safe refactoring for other stringification routines.
# v 1.1.4 2015-09-09 [stable]
This release is mostly a bug-fixing release.
One major bug (leading to crash) was found in the G2 frame parsing layer: a
carefully crafted G2 packet sent to GTKG could crash it, leading to a Denial
of Service. For that reason, an upgrade to 1.1.4 is strongly recommended.
The only major new feature is the added cleanups of the TTH cache and the
crash log directory, to make sure we do not keep useless files on the disk
forever.
Because the Phex servent is no longer maintained, there is now a workaround
for that particular servent to ensure it can correctly download from GTKG.
Improvements:
- [GTK2] Added tri-state column sorting in "property editor" preference pane.
- [GTK2] Show icon + warning message when we have no TCP listening socket.
- Added an "install-strip" target to all Makefiles to install with stripping.
- Can no longer edit properties flagged as "internal" through shell or GUI.
- Added new "session_start_stamp" property to hold the true starting time.
- Added support for TTH cache cleanup.
- Added automatic cleanup of the crash log directory.
- New shell command "random stats" to display the statistics on random layer.
- Workaround for Phex: always send X-Gnutella-Content-URN in upload replies.
- Updated GeoIP database.
Bug Fixes:
- upnp_natpmp_discovered(): detect when UPnP layer was shutdown and abort.
- Fixed bad definition of XXTEA key, which led us to use only its first 4 bytes.
- node_g2_read(): need to only read 3 bytes usually to determine frame length.
- thread_sp(): tweaked to defeat gcc 5.x optimization leading to a NULL return.
- File moving: notify main thread as soon as file is completely copied.
- update_available_ranges(): lack of X-Available means file is full on server.
Under the Hood:
- Windows: added getppid() and statvfs() emulation, plus rmdir() support.
- Improved the unpredictability of our random numbers.
- Loudly warn if attempting a file-descriptor operation on a revoked descriptor.
- Added compat_sendfile() with fallback to emulated version when necessary.
- Added compat_statvfs() for portability and code simplification.
- File moving operations now use sendfile() if available.
- XFMT: made it loudly clear that comment nodes are ignored for now.
- VMM: when debugging, trace large allocation spots.
- VMM: raised maximum page cache lifetime from 3 to 15 minutes.
- page_cache_find_pages(): treat user memory as if under short-term strategy.
- filepath_basename(): optimize code when G_DIR_SEPARATOR is '/'.
- Optimized CMP() to avoid branching regardless of the arguments.
- Added ftw_foreach() to traverse a file system and process each entry.
- mingw_readdir(): do not change errno if it was left untouched by _wreaddir().
- Let mingw_{opendir,readdir,closedir} use normal types, not generic ones.
- mingw_stat(): added workaround for trailing "/" or "/." in paths.
- etree_traverse_internal(): minor optimization to avoid trailing +1 each time.
- Added etree_sort() and etree_sort_with_data() to sort children of all nodes.
- Changed signature of decoding base16 and base32 routines.
- Regenerated Configure to fix the fdopendir() compile test.
- Make sure pointer hashing distributes its trailing bits evenly.
- elist_merge_sort(): don't update tail, just do one single pass at the end.
- vmm_dump_pmap_log(): copy pmap data, then process dumping without locks.
# v 1.1.3 2015-04-08 [stable]
This is mainly a critical bug-fixing release, addressing a huge shortcoming
in 1.1.2: all Shareaza leaves are incorrectly flagged as being fakes and are
being removed quicktly from ultrapeers, creating network churn and instability.
Everyone running gtk-gnutella as Ultrapeer must upgrade to 1.1.3 quickly.
Releasing quickly after 1.1.3 is also a pretext for improving stability on
Windows platforms, especially after restarts: because Windows does not support
the "close on exec" flag on file descriptors, restarted processes were left
with several instances of a listening socket bound to the same port, causing
havoc as behaviour is totally undefined and was most probably leading to the
inability for the process to get any incoming connections.
On Windows, we now also monitor the memory usage more closely, in order to
avoid the C runtime from issuing a (blocking) popup signalling a fatal memory
allocation error should it run out of space.
More generally, the VMM layer is now capable of trapping fatal memory
allocation errors and handling them more efficiently. In particular, when
everything has failed, the layer can request a brutal restart of the process.
Under less dire circumstances, a graceful restart will be requested.
This was also an occasion to revisit the long-term allocation strategy in
the VMM layer and optimize it in order to further limit fragmentation of
the VM space. Even though avoiding fragmentation matters mostly for 32-bit
applications, this also limits the amount of individual memory region mappings
the kernel has to maintain and gtk-gnutella has to keep track of.
Finally, a last-minute bug fix where a user reported a deadlock in the QRP
processing code. After investigation, it turned out that there was indeed
a recursive locking on a spinlock that had escaped all real-life testing out
there so far!
Improvements:
- [GTK2] Added popup menu icon in front of "force push mode" for sources.
- [GTK2] Added warning icon in status bar when kernel runs short of net buffers.
- Increased default node connection timeout and size of the quick connect pool.
- Updated the shell "status" command to display "!IP" on net buffer shortage.
- Updated FAQ along with French and Turkish translations.
- Updated GeoIP databases.
Bug Fixes:
- Fixed invalid test for "fake" Shareaza that led to network instabilities.
- Made QRP lock a mutex to allow for recursive locking through qrp_comp_done().
Under the Hood:
- On out-of-memory conditions, attempt to auto-restart if possible.
- Windows: monitor committed memory, crashing before the kernel would kill us.
- Added crash_restart() and controlling routines to request smooth restart.
- On network buffer shortage (ENOBUFS), stop TCP connections for a while.
- UPnP: protect upnp_mapping objects given to callbacks with reference counts.
- Adjusted lock tracking when locks are disabled, fixing lock swapping.
- Windows: remember socket descriptors so that we can close them on exec().
- Refactored code for listening sockets to warn when bound port is already used.
- When shutdowning in "crash mode", skip most of the memory cleanup.
- rwlock_destroy(): make sure to write-unlock the lock if it was owned.
- waiter_ack(): don't panic if waiter was not notified, but loudly complain.
- upnp_map_natpmp_publish_reply(): trace given port on NAT-PMP mapping errors.
- upnp_discover(): force selection of IPv4 interface for UPnP discovery.
- thread_unsuspend_others(): relaxed hard assertion into a soft one.
- alloc_pages(): try harder on OOM conditions to allocate from the page cache.
- socket_connect_finalize(): fixed wrong errno processing for connect().
- socket_connect_prepare(): no need for SO_REUSEADDR for connecting sockets.
# v 1.1.2 2015-03-21 [stable]
This is mainly a bug-fixing release, addressing rare crashes that have been
happening in production. It also contains several improvements.
It fixes a user-reported bug whreby it was not possible to properly configure
the download paths using the GUI -- that led to application crashes due to
the incomplete support for discovered threads (which GTK is using underneath
to manage the dialog box).
Another bug was caused by the HTTP header parsing logic which did not allow
"." in header names. That made it refuse to parse headers sent by some UPnP
devices, such as "BOOTID.UPNP.ORG" or "CONFIGID.UPNP.ORG", prevening UPnP
mappings from being installed.
Hapening rarely but still annoying, there was a bug on the error handling path
of write errors to the TX network stack, leading to assertion failures in
the mq_tcp_putq() routine. That was because the qrt_compressed() routine
was not handling task cancellation properly. The likelyhood of hitting that
bug when running as a leaf node was very low.
On the improvement side, the search list is now highlighting searches for
which we have associated downloads by displaying the text in green. Further
tweaks were made to our GTK2 code to make sure the changes are reported "real
time" when the state changes, which was not always the case before (one needed
to go over a search by explicitly clicking on it to update the display in
the search list).
The SHA1 computation code was also further optimized to be as fast as possible,
reducing file hashing time by two! Since SHA1 hashing happens regularily
in gtk-gnutella to collect entropy, optimizing the SHA1 computation affects
more than just file verification.
Improvements:
- [GTK2] Added translation URL in the "About" GUI dialog.
- [GTK2] Highlight searches with registered downloads by using green text.
- [GTK2] Added tri-state column sorting to the "upload history" panel.
- FAQ: added new entry explaining how to get the magnet of a shared file.
- Map the "collection" G2 query tag to the Windows / Linux "archive" file set.
- Map the "torrent" G2 query tag to the "torrent" file set.
- Added support for "rom", "wordprocessing" and "subtitle" G2 query media types.
- Further optimized SHA1 computation, now going about twice faster for files.
Bug Fixes:
- page_cache_insert_pages(): fixed incorrect write-lock upgrade logic.
- pmap_insert_region(): must recompute insertion index if we extend the pmap!
- tmalloc: fixed thread magazine accounting in the depots.
- Did not commit back to database after updating the DHT key request count.
- routing_chunk_move(): must check messages carefully when chunk was moved.
- route_message(): beware of check_duplicate() which can remove the node.

- qrt_compressed(): was not handling QRP compression task cancellation properly.
Under the Hood:

- dir_entry_filename(): made the Windows version thread-safe.
- hfield_dump(): fixed formatting of continuation lines.
- dmesh_collect_locations(): only parse the last timestamp when many given.
- xmalloc_thread_free(): always handle blocks in the cross-thread free list.

# v 1.1.1 2014-09-02 [stable]
This is mostly a bug-fixing release.
Improvements:
- Share Opus files by default, added opus and webm to search filters.

- Allow xfl_find_freelist_index() to work with gcc 4.9 and optimizations.
- keys_offload(): do not process if the key layer was shutdown.
# v 1.1.0 2014-07-02 [stable]
This is a major release introducing new features and making gtk-gnutella
a multi-threaded application with drastic performance boosts for background
tasks like file hashing or library rescanning.
Another major feature is the added support for the G2 search protcol: we are
connecting to G2 hubs as a leaf, answer to search / browse requests from G2
hosts. We also use G2 to issue our own searches. Finally, we freely exchange
files with G2 hosts (downloading and uploading).
The G2 protocol was further extended to make sure G2 query hits convey as
much information as Gnutella query hits, in particular for alt-loc propagation
and TLS support. The G2 semi-reliable UDP layer is also leveraging the new
features designed for the corresponding Gnutella layer (cumulative and extended
acknowledgments), gracefully falling back to legacy features if the remote host
is not able to understand the new features.
A critical bug was fixed: reception of carefully crafted invalid DHT messages
would lead to an immediate crash, an open door for Denial of Service (DoS)
attacks. That bug has been present since 0.97 (release of August 2011).
Last but not least, the code base has now been checked by Coverity. There was
a very low defect rate of 0.26 (amount of true defects per thousand lines
of code) and all problems were fixed.
New Features:
- Multi-threading support (file hashing, library rescan, DNS, etc...)
- Added support for the G2 search protocol, connecting as leaf mode to G2.
- Turned gtk-gnutella into a random number server through the "random" command.
- Removed Bitzi support since the service has shutdown.
- Added the --no-dbus command-line option to prevent D-BUS notifications.
- [GTK] Added GUI enabling of the G2 protocol for searches.
- [GTK] Added spin-button to set the amount of G2 hub connections to maintain.
- [GTK] Report amount of G2 hubs to which we are connected.
- [GTK] Show amount of G2 host browsing served, in the upload stats pane.
Improvements:
- [GTK2] Added tri-state column sorting to "Downloads" and "Uploads" panes.
- Better entropy collection to initialize the pseudo random number generators.
- Externally visible randomness (e.g. GUIDs) is now cryptographically strong.
- We now pick random DHT nodes to send back from the whole routing table
- Some entropy collected is persisted, for better reseeding in next session.

- keys_update_value(): forgot to persist back updated expiration timestamp.
- Properly flag UDP route as deflatable when GGEP "Z" is seen in queries.
- Flag UDP route as supporting semi-reliable UDP when query flags are parsed.

# v 1.0.1 2013-12-31 [stable]
This is a minor release correcting a grave bug causing gtk-gnutella to think
all other gtk-gnutella out there are hostile.
Other minor improvements are present, as well as low-level bug fixes. The
most visible change is that filenames with parentheses are now mangled to
have the parentheses turned into brackets, instead of being left as-is. This
allows filename cut-n-paste into shell commands, without having to use the
shell auto-completion to escape the parentheses.
Improvements:
- Generate a NM/1.0 HTTP-like header at the top of the pre-computed nm list.
- [GTK] Avoid GUI flickering when widget sensitivity is changing quickly.
- Replace "()" with "[]" in filenames for easier cut-n-paste in shell commands.

features such as the ability to limit dropping of received UDP messages,
making the DHT keys and values persistent across sessions, SDBM file

# v 0.98.4 2012-11-04 [stable]
This is an important release correcting severe bugs affecting the overall
wealth of the system: the PARQ upload queue was not properly restored, the
DHT was not always sending correct values back (resulting in failed lookups),
and SDBM (our hash-on-disk database) had two well-hidden bugs that could cause
crashes at startup or that compromised regular runtime operations.
This release also introduces an interesting improvement: we are now using a
reliable UDP layer to transfer out-of-band query hits, ensuring that these
important messages are properly sent and received and never lost.
The SPAM-detection on query hits received via UDP was too eager to discard
results from perfectly valid sources, causing improper loss of results from
your queries.
We were also wrongly sending out more queries than necessary: a long-standing
bug caused locally-issued OOB-proxied queries to be re-emitted a second time,
and we were re-forwarding duplicate queries (received with higher TTL than
before) to all the leaves. Although not harmful, these two bugs were wasting
some of the outgoing bandwidth when running as a ultra node.

# v 0.97.1 2011-09-11 [stable]
This is a bug-fixing release, addressing critical bugs that slipped through
in the 0.97 release but which happen only in particular conditions.
The project also switched from SVN to git. This affects the version number
which no longer includes a single SVN revision but instead uses the combination
of a counter for the number of changes since the last release plus git's
abbreviated commit ID.
Bug Fixes:
- Fixed bootstrapping problems on IPv6 enabled hosts [bug #3376322].
- Forgot to clear global HTTP handle on GHC errors [bug #376322].
- Typo caused crash when processing alternate locations in firewalled mode
with PFSP enabled.
- Forgot to clear pending THEX downloads on download stops.
- Make sure we remove the SHA1 of de-indexed files from the shared set.
- Handle "message too large" errors when sending on UDP.
Under the Hood:
- When running as ultra node, use GUESS introduction pings when requesting
a query key so that the remote ultrapeer can passively discover us.
- Do not count GUID collisions with our own GUID when we see our own IP:port!
- Added some gcc 4.6 "hot" / "cold" routine tagging for better optimizations.

- Integrated spell check of the French translation from stegozor@gmail.com.
- Turned "zalloc_always_gc" to FALSE by default.
# v 0.97 2011-07-18 [stable]
This is a major release, fixing critical long-standing bugs and introducing
handy new features. It is also the first stable release for Windows.
New Features:
- Added HTTP request pipelining.
- Added GUESS (Gnutella UDP Extension for Scalable Searches).
- Added the ability to look for specific media types.
- Added the ability to query for partial files as well.
- Added "What's New?" queries.
- Added smart search stopping / resuming options.
- Added command-line option --minimized; useful when auto-starting gtk-gnutella.
Improvements:
- Improved unpredictability of random numbers.
Continuously collect new randomness from message events (RX, TX, dropping).
- No longer uses download overlaps as soon as we know the TTH of the file.
- When the download queue is auto-frozen due to lack of space, monitor the
filesystem to auto-unfreeze when enough space is available again.
- Can configure different amount of limits for various kind of search results.
- [GTK2] Added missing configuration option for case-insensitive sorting.
- [GTK] Flag search results bearing an alien IP as such, using both a tag
(alien) and a color (deep pink).
- [GTK] Added option to discard results bearing an alien IP (TRUE by default).
- [GTK] Added option to restart session-only searches that still have pending
downloads registered (FALSE by default).
- [GTK] Search details now include a line to display available metadata.
- [GTK] Fill in the Bitzi metadata column on the fly as results come in when
we have cached ticket information available.
- [GTK] Show media type filter attached to query, when known, in the search
detail window.
Bug Fixes:
- Fixed *grave* routing bug whereby TTL was wrongly trimmed down by one
extra step. Furthermore, the trimming threshold was wrong, which in effect
caused ultrapeers to drop queries with TTL <= 2.
- Fixed *grave* routing bug: was sending TTL>1 queries twice on the same
connection when running as ultrapeer.
- Fixed *grave* routing bug: was not properly forwarding duplicate OOB-proxied
queries with a higher TTL (MUID was not altered the second time).
- Make sure ~ expansion is done for path variables when changed at runtime.
Fixes bug #3215847.
- Was not processing updates of "search_reissue_timeout" from the GUI!
- Filename sanitizer led to a crash when given a filename with leading spaces.
- TTH downloads would crash when not receiving any data back.
- An off-by-one bug prevented proper token validation, causing GTKG to not
properly recognize the latest releases.
- Avoid crash when attempting to connect to a node that would be internally
flagged as "useless".
- Fixed chunk selection algorithm to properly request from servers providing
partial files.
- Various "crash at shutdown time" type of fixes (occuring rarely and randomly).
- Plugged hole leading to a file completing but not being checked for its SHA-1
when we have a few sources competing against each-other and all these sources
end up ignoring data to preserve their connection.
- Fixed crashes with GTK2 on some platforms at quit time by ignoring duplicate
"quit" requests.
- Fixed race condition that could lead to an incomplete QRP configuration.
- Fixed important LRU cache management bug in the SDBM layer, which was causing
data loss in persisted databases.
- Head pings had their GGEP "PUSH" key improperly parsed.
- [GTK] Was not saving the column size of the search list.
- Fixed cause of random crashes in the VMM layer on systems using mmap() to
serve uploaded files.
Miscellaneous:
- Dutch translation updated.
- French translation updated.
- By default, auto-clear completed and failed chunk downloads.
- Changed user-visible connection state wording: "Connected" -> "Receiving" or
"Awaiting data".
- Added documentation for DHT "NOPE" values.
- Allow one to disable partial file sharing in general, enabling it only for
rare files (no full copy present).
- Moved SDBM files to dedicated directories, either "gnet-db" or "dht-db".
- Added visual indication that the download queue is frozen.
- Added GUI configuration for "tth_auto_discovery".
- [GTK] New colors for search results, to quickly spot partial hits, alien hits,
hits with media-type mismatch and hits from firewalled sources with no
push-proxy listed.
- [GTK] Added expert-level configuration for the DHT mode, for whether DHT
keys/values should be kept in memory, and for the SPAM SHA1 look-up table.
- Option --disable-ipv6 was removed from build.sh: we now always compile with
IPv6 when Configure detects OS support.
Under the Hood:
- Tweaked aggressive chunk selection logic.
- Let the RX link layer use the configured socket RX buffer size to determine
the maximum amount of data that we can attempt to read in one system call,
when the input layer cannot let us know how much data is pending.
- Ensure we only keep valid address and port information when merging PUSH
servent addresses for a given GUID.
- Make sure fast assertion routines are never inlined or it would perturb
stack traces due to missing offsets.
- When building search request, be careful to not include unnecessary bloat at
the end of the extension block or other GTKG nodes will drop the query.
- DHT statistics now show local k-ball info along with the theoretical one.
- Added probalistic model to randomly avoid cached DHT values too far from the
key's theoretical k-ball during value lookups.
- Smarter handling of "duplicate DHT values" (coming from the same publisher).
We now allow fetching of these duplicates and retain different versions of the
same value if we find a discrepancy (due to caching or partial re-publishing).
- PUSH flooding detection no longer bans offending hosts, but only regulates
the traffic by dropping flooding requests.
- Compact extensions of forwarded queries to remove needless bloat: the XML is
compacted, legacy HUGE requests to return URNs in hits are dropped, GGEP
payload that are large enough are possibly compressed.
- s390(x) has IEEE 754 floats.
- Handle GGEP "u" in queries (SHA1 and bitprint URNs).
- Avoid showing "negative" retry delays.
- Turned some debugging-only assertions off.
- Fixed bad test that led to a crash when receiving improper FIND_NODE messages.
- Removed dependency to libxml2: now uses built-in XML support.
- Converted bitzi cache to a persistent SDBM-based database.
- Faster Bitzi request scheduling.
- The Gnutella routing table now dynamically adjusts its size.
- Deprecated GGEP "GTKGV1" in query hits, replacing it with "GTKGV".
- Make sure we never send back duplicate SHA1 hits, even if they are sharing
twice the same file from different directories.

that were not exercised during pre-release testing are responsible for
fatal errors (sudden crashes due to assertion failures).
Bug Fixes:
- Removed an obsolete assertion now that gtk-gnutella supports NOPE DHT values.
This was causing a crash each time a NOPE value was received in response
to push-proxies queries in the DHT.
- Fixed memory alignment problem for non-forgiving CPU architectures.
- The virtual memory manager would crash when the kernel starts allocating
pages in zones we wrongly thought were already used.
- Fixed long-standing bug in the Query Routing Table protocol where a RESET
message with the wrong table size could sometimes be sent, causing the remote
node to close the connection.
- Make sure an ultrapeer is not publishing NOPE values in the DHT if support
for the DHT was disabled by user, which would be triggering a fatal assertion
failure.
Under the hood:
- Fixed Makefile to ensure proper compilation under Gentoo's build scripts.
- Push-proxy client support now makes sure there is a space after a leading
GET or HEAD word in the HTTP request.
- The DIME parsing layer now given more information in case of an error.
- Let THEX downloads peruse any supplied Content-Length information from the
server (applicable only when the output is not chunked).
- The VMM layer is now smarter at identifying foreign pages when allocating
blocks larger than a single page.
- When sending BYE messages, do not shutdown the socket layer if using TLS.
- Compilation cleanup for SunOS, Sun Studio, and versions of GTK < 2.5.0.
# v 0.96.7 2010-03-07 [stable]
Bug Fixes:
- Fixed memory leaks.
- Do not unduly rewrite fileinfo trailers on restart, messing with the "mtime"
filesystem information.
- We were never forwarding to other ultra nodes queries that did not
have a TTL of exactly 1 (severe bug impacting the network).
- Queries not kept for a local file match were most often dropped and not
forwarded (severe bug impacting the network).
- Corrected detection of largefile support in Configure.
- Fixed oversight in token validation, to be able to verify older versions.
- Fixed metaconfig unit for systems without kqueue().
- PARQ complained about lack of X-Queued header even if HTTP status was not 503.
- Fixed sending of QUEUE callbacks to avoid hammering remote host, or stopping
alltogether at the first timeout detection.
- Was sometimes failing to reconnect to more nodes after disconnections.
- Inverted logic was causing repeated UHCs queries when under the minimum
amount of peer connections, causing undue traffic.
- Tigertree verification would sometimes crash and delete the wrong slices
after a TTH mismatch.
- Fixed crashes at shutdown time due to inappropriate dropping of new messages
in the message queues.
- Fixed crashes at shutdown time due to improper checking in the dynamic
query cleanup code.
- Fixed invalid boundary test when server shrinks the requested file chunk.
- Unfreeze all PARQ entries from the IP after serving a quick slot, or we
could have several frozen entries for that IP with no possible escape.
- Receptions of "GIV" and "QUEUE" were not checking whether the remote address
was an hostile one.
- Changed the Bitzi ticket-requesting URL, as the previous one was no longer
responding correctly.
- Fixed push-proxy support: requests (LIME/21) now only use v1 and acks
(LIME/22) only use v2 because this is what LimeWire expects. GTKG was
sending LIME/21v2 which confused LimeWire, in effect disabling the ability
of GTKG to act as a push-proxy.
- GUI node flags were not updated upon reception of a Push Proxy
Acknowledgement (indicating the node became one of our push-proxies).
- Fixed status bar which lost the GTKG URL as soon as a new version was
announced.
- Fixed crash when a compressed connection was closed and had never been
given any data to compress.
- Fixed behaviour on DHT value lookups when the key exists but is not holding
the proper value types.
- Fixed HTTP partial range merging logic.
- Fixed logic for push-fallback on connection timeouts.
- Fixed improper GUI status display when connecting to a push-proxy.
- Could wrongly discard a perfectly good push-proxy.
- Prevent "found more recent metainfo" warnings at next startup by properly
flushing the metainfo database at shutdown time.
- The "Force push mode" menu entry could have no effect if gtk-gnutella had
determined the host did not require a push.
- Avoid innocuous duplicates in the persisted download file.
Improvements:
- Better resuming of downloads on session restarts.
- Increased success rate on downloads from firewalled hosts.
- Completed support for DHT publishing: DHT is now fully functional.
- DHT bandwidth usage is now disaplayed in the GUI.
- Added support for GGEP XQ (eXtended Query) as used by LimeWire for search
terms longer than about 30 characters.
- Try to decipher incorrectly encoded query flags from buggy Shareaza.
- Parse incorrectly formatted X-Alt header from buggy Shareaza.
- Implemented PFSP 1.0a: now emits and handles new X-Available header.
- Added some MIME types and file extension mappings.
- Added comand-line switch --compile-info to print some information
that is hardcoded at compile-time.
- Persist known TTH roots in magnets.
- Swapped leaf and ultrapeer slots for GGEP UP in compliance with LimeWire
which does not follow the published specification (so we don't either now
but we are compliant with the de-facto standard).
- Will now remove uncompressed ultra connections when full and getting a
new compressed one.
- Whitelist can now support TLS hosts and will refresh DNS mappings regularily.
- Improved granularity of the background task used to scan the library in
order to prevent noticeable processing freezes as much as possible.
- Redesigned the output of the shell "status" command to show more information
and display status flags (shown as icons in the GUI).
- Added liberal parsing of urn:sha1: and urn:bitprint to cope with clueless
sites using hexadecimal instead of base32 to encode the hashes.
-Added -v option to the shell command "props" to also display values along.
- Added real shell-like string parsing, and fixed escaping to work correctly.
- Added the ';' separator to be used to separate mutiple shell commands.
- Allow crashes and fast assertions "soft" failures to be timestamped.
- Don't answer to UDP pings from bad nodes, which include "alien" hosts.
- Loop through the TCP push-proxies more quickly until one can relay our push.
- Passively revitalize PUSH routes and wakeup starving downloads.
- Attempt to collect push-proxies passively from relayed query hits.
- A completed file waiting for being moved accross filesystems will now
be flagged as such in the GUI "Downloads" pane.
- Detect and fix improper 503 HTTP status code replies when 416 was meant
(broken HTTP replies from Foxy, Shareaza, and maybe others).
Under the hood:
- DHT (Distributed Hash Table) is now enabled by default.
- Reduced blackout period between two DNS server name lookups to 30 minutes.
- Updated PFSP specifications (partial file sharing) to version 1.0a.
- More statistics.
- Always use exact time when logging, not the cached time.
- Align to LimeWire's settings for DHT expiration and republishing periods.
- Do not emit any PFSP header when seeding a finished file.
- Even if bandwidth is tight, force emission of the X-Hostname header under
certain circumstances because this information is precious.
- No longer constantly monitors for unsolicited UDP traffic, which will save
precious CPU cycles.
- Improved malloc tracking by reporting symbolic names in stack frames.
- Optimized ultrapeer TX compression settings to reduce memory requirements,
saving 288 KiB of RAM per Gnutella node connection (leaf or ultra).
- Increased default amount of ultrapeer connections to 42.
- Optimized memory footprint of the simple hashtable and allow it to be
downsized as well.
- Consider a HEAD Ping message to be unsolicited UDP traffic.
- New shell command "memory dump" available when malloc stats compiled in.
- Some documentation held in SVN cannot be packaged on Debian, so it was
moved to a separate directory that is left out from the packaging manifest.
- SDBM improvements for greater runtime performance and data consistency.
- Added DHT root node caching (k-closest nodes of a target KUID).
- Tuned DHT node lookups for more performance.
- Can now hold the SPAM look-up table in an SDBM database instead of memory.
- The directory holding "incomplete" files is now lock-protected to prevent
two different gtk-gnutella instances from using the same one.
- Added long-due zone garbage collector, called when gtk-gnutella is "idle".
- Tuned block size to avoid wasting too many bytes in zones.
- Improved the virtual memory management layer to limit fragmentation,
especially for servents running over long periods of time (weeks).
- Revised the vitrual memory management page-caching algorithm.
- Politely deny handshaking with peers presenting an X-Auth-Challenge header
or an FP-Auth-Challenge one.
- Added support for firewalled alternate location collection and propagation
through the X-Falt header (requires that the "fwalt/0.1" feature be
advertised in X-Features).
- Added a non-persistent "alien" cache to keep track of IP:port of nodes
that do not belong to the Gnutella network.
- Increased the buffer size of datagram sockets to 32KiB to allow reception of
bigger messages: it is not uncommon to get OOB query hits larger than 4KiB.
- Count (and show) amount of launched SHA-1 and TTH file verifications.
- Translation updates.
Limitations:
- DHT code is currently sub-optimal for firewalled hosts.
- Manual bandwidth tuning is currently necessary to allow for efficient
DHT usage. Allow at least 8 Kib/s out, 15 KiB/s out being better.
Also increase the lookup bandwidth to 32 KiB/s in and 6 KiB/s out, the
defaults of 8 KiB/s in and 2 KiB/s out being very conservative.
- DHT is enabled by default with a fixed (manually tunable) configuration.
There is no auto-tuning and no adaptation to traffic conditions yet.
You need to explicitly disable the DHT if you don't want to benefit from it.
# v 0.96.6 2009-03-29 [stable]
Bug Fixes:
- #1932909 "columns in search window do not scale properly".
- Fixed improper HTTP chunking when outputing chunks larger than 64 KiB.
- #2628899 "tries to download from my old self after IP changes".
- Was not always resuming the interrupted SHA-1 computation of a finished file
when servent was closed in the middle of processing.
- Fixed bad range checking test in the download part.
- Was not paying attention to the "give_server_hostname" property and instead
sent "HNAME" GGEP extensions in query hits provided a non-empty name was
defined as the "server_hostname".
- Fixed improper upload slot counting which introduced race conditions,
sometimes leading to having more slots used than the configured maximum
(in addition to the "quick" upload slots).
- Prevent occasional crashes at shutdown time, during subsystem cleanups.
- Fixed corner cases where we could lose a server hostname and downright bug
where we discarded the hostname after a DNS lookup if the subsequent
connection attempt did not succeed.
Improvements:
- Refuse to share certain directories: /, $HOME, $GTK_GNUTELLA_DIR, and
the incomplete and corrupted directories.
- Downloads GUI: added checkboxes to invert the select/filter patterns.
- Downloads GUI: added "Modified" column and detail showing the timestamp of
the last file modification.
- Optional beautification operations on filenames: strip leading "-", remove
consecutive "_" and prevent "_" surrounding punctuation characters.
- Fixed significant performance issue in the Gtk+ 1.2 front-end: update of
upload statistics was O(n) but is now O(1).
- Background TTH file verification now lights an icon in the GUI.
- Show TTH tree depth in the download "Details" pane.
- Update the bitzi metadata info box when a query finishes, so that it is
not required to click on the result again after requesting bitzi data.
- Added MIME type column for search results.
- Added "Last Request" and "Last Upload" columns to the Upload History.
- Almost complete DHT support (missing only publishing of data), but code
needs to be explicitly enabled by setting "enable_dht" to TRUE. The DHT
knows how to look for alt-locs for files and push-proxies for firewalled
hosts, and will store local data for others to query.
- New shell commands "stats", "download", "echo".
- It is now possible to rename files being downloaded (through GTK2 or shell,
no support in GTK1).
- Added more filename extensions to the built-in search filters.
- Switch resources after getting an HTTP error if the connection is kept alive
and the error permits follow-ups (non-busy conditions).
- Improved ability to switch resources after file completion by ignoring
trailing swarming data, to keep the connection alive.
- Bitzi tickets are refreshed when explicitely requested, avoiding reuse
of stale metadata
- Completed files are displayed during hash verification.
- Only propagate good alt-locs for files we are downloading, i.e. addresses
of hosts which we know to be serving that file because we contacted them.
- Many new statistics counters.
- Allow scheduling of special downloads without considering per-host limits,
as these are of a much shorter duration (THEX and browse host requests).
- Always seed completed files, regardless of their size (no PFSP minimum as
with partial files), when their SHA-1 has been verified.
- Incorrectly encoded Bitzi metadata is translated to Unicode.
- Browse-host responses are sorted alphanumerically on relative pathnames to
allow users to relate files together if they don't understand GGEP "PATH".
- Improved routing of PUSH messages by also looking whether targetted hosts
happen to be one of our immediate neighbours.
- Updated Norwegian Bokmal and Spanish translations.
Under the hood:
- Parse legacy Shareaza THEX URIs "urn:tree:tiger/:" (extra "/" here).
- Handle non-standard X-Thex-URI headers if peer provides a valid
X-Content-URN header (Shareaza 2.1.0.0).
- Also attempt to give priority to the last "pfsp_last_chunk" bytes of
downloaded files, since that can contain important indexing information to
enable pre-view of partial video files.
- More MIME types known (derived from file extensions).
- Can now download THEX data at a tree depth of 11 for files larger than 1 GiB.
- Can download sub-optimal THEX data, as non-optimal data is better than none,
but keeps looking for THEX data at the optimal tree depth nonetheless.
- Reimplemented scanning of shared directories as a background task so that
the process (not just the GUI) is fully responsive during the whole scan.
- Let the background task scheduler compute the proper amount of ticks to
use for each task.
- Upload statistics now record the file's SHA-1, so that we can consolidate
partial file sharing with library sharing statistics, with the filename
being forced to the library's filename.
- Avoid starting moving a completed file if there is not enough space on
the targetted file system.
- Recognize and propagate the "DHT" GGEP extension in pongs.
- Added support for "DHTIPP" GGEP extension in pings, used for DHT bootstrap.
- Added more entropy to the random number seed.
- Plugged memory leaks
- No longer send SHA-1 queries on the Gnutella network. They are now performed
through the DHT, which has the suitable topology to do so efficiently.
- Fixed UDP bandwidth computation, and removed any limit on UDP incoming.
- Updated list of hostile IP adress ranges, Geo-IP data, spam patterns and
spam samples.
- Property loading from files was in O(n*n), made it O(n).
- Now detect property files being blindly copied over from another
gtk-gnutella's config directory and reset properties whose value needs to
be unique.
- The GUID and the KUID (Kademlia ID, the DHT node ID) were made sticky.
- Optimization of QRP lookups in tables ranging from 16k to 2M slots.
- Limit amount of hits to 10 per query hit packet, as LimeWire chokes otherwise.
- Limit amount of alt-locs in hits to 10 or LimeWire chokes.
- Keep connection alive when reporting an HTTP error to allow remote resource
switching if necessary.
- Emit and parse new X-Downloaded header, apparently introduced by LimeWire.
- Added parsing of X-FW-Node-Info headers to grab push-proxies from firewalled
hosts, as well as gather the proper GUID and host address/port.
- Emit X-FW-Node-Info if node is firewalled but continue to list our
push-proxies in the standard X-Push-Proxies header.
- Avoid endless aggressive chunk splitting during swarming.
- Proper parsing of comma-separated values in Accept and other Accept-Encoding
HTTP headers.
- Reject UDP packets from unspecified addresses.
- Drain more data out of the UDP receive buffer to prevent it from filling up.
- Strip at most 5 trailing characters from words when building the QRP table,
thereby inserting less radices and making the table more sparse.
- Removed workarounds for dealing with broken 0.96.2 nodes and earlier 0.95.x.
- Extended syntax for push:// exact sources in magnets to be able to supply
all the known push-proxies, even if that is an empty set. Since downloads
are persisted as magnets, this also allows keeping all the previously
known push-proxies accross sessions.
- Upgraded PARQ to version 1.1 (mostly specification cleanups).
- Added additional anti-hammering for cases where many files on the same
server are queued and gtk-gnutella is configured to launch more than 1
connection per IP. Connection attempts to the same server are now limited
to 5 per minute.
Limitations:
- DHT code is still experimental, although functional: configuration of
parameters can only be done through the shell, and there is no support
for publishing yet.
# v 0.96.5 2008-04-01 [stable]
Bug Fixes:
- #1870957: Wrong sign could cause out-of-bounds read and potentially a crash.

- Removed default shared filename extensions: .doc
- Updated translations: Japanese, Norwegian Bokmal, French.
Under the hood:
- Changed default to dual use of IPv4 and IPv6 instead of IPv4-only.
- Support the "as" (Alternate Source) key in magnet links.

- Take full advantage of persistent HTTP connections to fetch multiple
files from the same peer through over the same connection if scheduling
permits.
- Improved TLS support and blocking detection.
- Updated list of hostile IP adress ranges, bogons, Geo-IP data,
spam patterns and spam samples.
# v 0.96.4 2007-07-07 [stable]
Bug Fixes:
- The download overlap checking was incorrectly detecting mismatches.
- A bug in the network queue caused frequent crashes (#1601523).
- A bug in the event timing caused failures after 25 days uptime.
- A stalling issue with TLS connections.
- The search retry timeouts weren't accepted (#1568205).
- The order of items in the search history was wrong (#1568206).
- The quick-connect limit wasn't respected causing too frequent
connection attempts during startup.
- Removed incorrect use of SF_NODISKIO flag for sendfile() on FreeBSD.
- Fixed crash that could be triggered by changing the listening port
temporarily to zero.
- iconv() was not used correctly which could cause wrong conversions
for longer strings.
- Generated filenames weren't properly restricted in length which
could cause crashes.
- There was a compile issue on NetBSD caused by namespace pollution.
- Added workaround for the issue that on Solaris only the file descriptors
0..255 can be used for stdio.
Improvements:
- Finished downloads are now seeded for the whole session or until
they are manually purged, if partial file-sharing is enabled.
- Server-side support for Tigertree hashes and THEX thanks to patches
provided by Martijn van Oosterhout.
- Improved spam filters.
- Slightly better drag & drop support.
- Removed GWebCache support so only UHCs are used for bootstrapping.
- Improved the shell interface somewhat.
- Downloads can be paused now.
- Added a simple query syntax for easier creation of result filters.
Under the hood:
- Added support for HEAD Pings and Pongs which improves the download mesh.
- Implemented for Out-of-Band result delivery protocol v3 which protects
against certain kinds of forged results.
# v 0.96.3 2006-11-09 [stable]
Bug fixes:
- Portability fixes which affect the ARM architecture.
- Ultrapeers could be unnecessarily demoted to leaves in auto mode.
- [GTK2] Fixed a bug that could cause spurious assertion failures or memory
corruption.
- Fixed bug that might have caused truncation of printed numbers in certain
places.
- Rewrite the upload_history file if the history was cleared.
- Fixed crash caused by an assertion failure that could occur if IPv6
support was disabled at compile-time.

- Updated list of bootstrap caches.
- Updated list of country names and codes for Serbia and Montenegro.
Improvements:
- Turkish translation.
- New shell commands: online, offline, props, status.
- The search list allows selection of multiple items and applying actions to
them now.
- Added a tray icon to hide the gtk-gnutella application windows. This
feature requires Gtk+ 2.10 or newer.
- Added a limit of downloads per file which defaults to 40 to prevent using
an unreasonably large amount of sources.
- Keep certain irrelevant columns empty for "local:" searches instead of
showing bogus data.
- Added README.Debian with instructions how to compile gtk-gnutella yourself
on Debian-derived systems.
Under the hood:
- Rewrote "fast" assertions so that they are sufficiently portable and do
not mess with debugging. Thus they are always enabled now which reduces
code size signifcantly.
- The TLS cache is now persistent without SQLite too.
- Disabled reservation of Gnutella slots and vendor limits because it's not
useful with the current population of Gnutella.
- Disabled GWebCache updates.
- Configure bails out now if a mandatory dependency e.g., libxml2, GLib,
zlib isn't available.
- Added -Wshadow to the default compile flags for GCC for even cleaner code.

- Fixed bugs in the dynamic querying logic that caused leaves to
receive very few results through gtk-gnutella ultrapeers.
- Fixed crash on 64-bit platforms when using the navigation tree.
- Fixed format mismatches in some translated message catalogs.
Updates:
- Updated French, Japanese and Ukrainian translations.
- Updated list of hostile IP ranges.
- Updated list of bootstrap caches.
- Updated list of country names and codes.
Improvements:
- Italian translation.
- Fairly complete support for magnet-links; magnets can be passed per
drag & drop or entered via the search box. Magnets can be generated
from the search results display and the downloads display through
the context menu.
- SHA-1 based spam filtering.
- Built-in spam detection for certain kinds of spam.
- [GTK2] Overhaul of the downloads display.
- [GTK1] Downloads can be sorted albeit the sorting does not persist.
- Compiling the topless is variant is now as easy as
"./Configure -Oders -Dd_headless".
- Support for several command-line options like "--help".
- A local shell interface accessible with "gtk-gnutella --shell".
- New shell commands "nodes" and "shutdown".
- All downloads are stopped now if the disk apparently filled up.
- Caching of TLS-support allows automatic use of TLS.
- ~/.gtk-gnutella/whitelist supports the "tls:" as well.
- More search results columns for experts (hidden by default).
- Diverse IPv6 settings can be configured in the GUI now.
- The setting "IPv4 and IPv6" works now; the default is "IPv4 only".
- Results bearing no SHA-1 are suppressed by default.
- Results from hostile IP ranges can be made visible; they are discarded
by default.
- One's own shared files can be search by using the prefix "local:"
for searches. Local searches uses regex syntax unlike Gnutella searches.
"local:" alone will list all shared files. Local searches results
allow drag & drop and generation of magnet links.
- Support of Socker for access to privileged TCP and UDP ports below 1024.
- Optionally bind sockets to a configured address instead of the wildcard
address.
- Support of IPv6-to-IPv4 Transport Relay Translators (RFC 3142).
Under the hood:
- mmap()-based memory allocation to decrease fragmentation and
increase performance.
- Support of socket option TCP_DEFER_ACCEPT (Linux).
- Support of accept() filter "dataready" (FreeBSD).
- Support of /dev/poll on Solaris and IRIX.
- Sharing of file descriptors so that we don't require a file descriptor
per swarm source but only one per file.
- Use of pwrite(), pwritev() for flushing download buffers.
- Reopen log files on SIGHUP if the command-line options --log_stderr or
--log_stdout are specified which is useful for topless mode.
- Disabled following of HTTP redirects.
- Support of "deflate" transfer-encoding for all downloads.
- Support for compression of UDP packets.
- (2006-04-22 - RAM)
* Moved downloads were not lingering in the GUI once completed.
- (2006-03-11 - RAM)
* Fixed improper UDP overhead accounting.
* Flush ASAP when file is overcommitted: we have more data buffered than
there are in the file.
# v 0.96.1 2006-02-22 [stable]
Bug fixes:
- Fixed issue when browse host is the only search in the list (bug #1421196).
- Reset download buffers on incomplete writes (fixes bug #1429981).
- Fixed ever-growing sidebar at each relaunch under GTK1 (bug #1421940).
- Fixed misdetection of chunk completion, causing undue abortion of downloads.
- Was wrongly showing the source download speed twice in download status.
- Range column was sometimes inexact in downloads.
Improvements:
- Print PFS indication for actively queued entries as well.
- Take buffered data into account when showing download progress.
- Downloads now show how many HTTP requests were made on the same connection.
- Try to reposition the main window correctly.
Configuration Changes:
- Minimum connection timeout is set to 15 seconds.
- Default for "maximum % of slots / vendor" raised to 90.
- (2006-22-01 - RAM)
* Further fix for #1421940, regarding the vertical position of the search
list on the sidebar, which continuously went off after each restart.
* Made root window position fixup more robust to avoid random jumps when
we cannot determine the window position correctly.
* Was wrongly showing twice the same b/w rate in downloads with more than one
source: the second rate is supposed to be the aggregated rate of all the
sources.
* Downloads now show how many HTTP requests were made on the same connection,
if more than one, by appending a "#n" at the end of the status.
* Only update the range in the GUI after we decided which boundaries we'll use.
* Added workaround against broken HTTP servers such as GnucDNA which don't
show us the HTTP version in their statuses.
* No longer need to fake presence of a README.debian: manifests were updated!
- (2006-19-01 - RAM)
* Fixed misdetection of chunk completion, causing undue abortion of downloads
each time a chunk was completed.
* Take into account buffered data when showing download progress, instead
of waiting for the data to be flused on disk to update the counters.
- (2006-16-01 - RAM)
* Minimum connection timeout is set to 15 seconds.
* Default for "maximum % of slots / vendor" raised to 90.
* Forgot to reset download buffers on incomplete writes (fixes bug #1429981).
- (2006-04-01 - RAM)
* Print PFS indication for actively queued entries as well.
- (2006-02-01 - RAM)
* Fixed issue when browse host is the only search in the list: it could not
be closed, and GTKG would dump a core at exit time. Fixes bug #1421196.
* Use conditionnal form when reaching "code that should not have been".
- (2006-01-30 - RAM)
* Fixed line incorrectly starting with a leading $ instead of %.
- (2006-01-26 - RAM)
* Desktop and png files are located in extra_files now, no longer at the
root of the source tree: fixed debian/rules accordingly.

* Configure updates to allow configuration of madvise(), sigaction(),
the SA_INTERRUPT flag for sigaction(), and FAST_ASSERTIONS.
- (2005-12-10 - RAM)
* [GTK1] Browse all the hosts of the selected entries like GTK2 does, not
simply the host listed in the detailed search information pane.

# v 0.96 2005-11.22 [beta]
New features:
- Browse Host (HTML and Gnutella), TLS and IPv6 support.
- Chinese and Greek translations of the user interface.
- D-BUS plugging.
- Added hot keys: F2, F8 and F9 (see menu View->...).
- Searches are now created with a configurable expiration date.
Improvements:
- Optimization of the UTF-8 processing.

Under the hood:
- Support for the epoll()/kqueue() system calls.
- More optimistic PARQ ETA, and PARQ back-off when QUEUE are unanswered.
- NFS-compatible session locking if anyone cares.
- Nifty property browser.
- (2005-11-21 - RAM)
* [GTK1] Added ability to launch a browse-host from a download or a node.
* Will now correctly mark as finished browse host entries which have
a known size (maked when they're done, that is).
- (2005-11-17 - RAM)
* Added counting of received bytes during host browsing.
* Better handling of sudden file size knowledge.
* Update GUI information when size of browse host is known.
- (2005-11-17 - JA)
* PARQ now backs-off everytime a QUEUE failed to send.
- (2005-11-15 - RAM)
* Added client-side "browse host" support in the core.
* [GTK1] Initial implementation of client-side "browse host".
- (2005-11-11 - RAM)
* [GTK1] Changed the way autoselection works in search results: it now
happens only when one selects the root of a folded tree, and it
auto-selects all the (hidden) children.
- (2005-11-10 - RAM)
* When a bg_task is killed, don't launch any more processing in the
"done" callback: this cause QRP compression to attempt to send data
on a node that was being removed.
- (2005-11-09 - RAM)
* Re-activated suffix filtering rules.
- (2005-11-03 - RAM)
* Added .srt (video subtitles) to the default list of shared extensions.
* Tuned algorithm for PFSP with low amount of sources: use the amount of
alive sources instead of the amount known in the mesh. Also request
the minimum filesize for PFSP as quickly as possible, but otherwise
request the smallest chunk size first to have rapid exchanges with the
remote server to gather more sources.
* Added GUI mapping for new pfsp_minimum_filesize property.
- (2005-10-31 - RAM)
* Don't pursue QRT patch sending when node connection has been broken.
- (2005-10-20 - RAM)
* When we know a small amount of alternate sources and PFSP is enabled,
always include ourselves in the X-Alt we generate to help propagation
of alternates, even if the bandwidth is saturated.
- (2005-10-02 - RAM)
* GTKG was not tracking the TTL of broadcasted messages received along a
given connection, thereby leading it to believe it was receiving undue
duplicates whereas the node was simply resending it with a higher TTL.
This unfortunate bug was introduced on 2004-08-28 so all 0.95.x suffer
from it...
* Added workaround to allow ultra connections to old (broken) GTKGs to be kept
without remote ending it abruptly: simply never send duplicates to those...
- (2005-10-01 - RAM)
* Fixed buffers_strip_leading() when the stripped size equals the buffer size.
- (2005-09-29 - RAM)
* Fixed buffers_strip_leading() when trailing I/O vector is emptied.
* Show estimated remaining time in the Download pane as well.
- (2005-09-28 - RAM)
* At exit time, one must not try to flush download buffers holding nothing.
* Performance improvement, especially when running as ultra peer.
- (2005-09-27 - RAM)
* Flush pending download buffers at exit time.
* [GTK1] When download is done / checking SHA1 / moved, update parent's
status in case tree is collapsed.
* [GTK1] Always freeze the Active and Queue pane trees, updating them only
once per second, as controlled via main_gui_timer(), or when a button press
* Show SHA1 checking status and file moving feedback in the Download pane.
* Revisited chunk size computation: use a more realistic estimate of the
potential concurrency we'll get, and account for the shrinking size of
the remaining data to be downloaded.
- (2005-09-26 - RAM)
* Added "download_buffer_size" and "download_buffer_read_ahead" properties.
* Buffer more data per download to avoid endless lseek()/write() system
calls when swarming with lots of sources, and try to reduce filesystem
fragmentation by writing more data at once.
was done that should trigger a display refresh.
- (2005-09-25 - RAM)
* Don't honour settings for monitoring node "bad IP / unstable" addresses
when we're low on pongs: we don't want to discard IP addresses or
connections and end up being forced to contact web caches for new addresses.
* Don't use alternate locations as source for "semi-pongs" when we're not
low on pongs: we can't know for sure that those nodes have free slots and
that their HTTP port is the same as their Gnutella port.
* Disable "monopoly protection" when we're low on pongs (fixes #1177512).
* [GTK1] Buffer updates to fileinfos to avoid too frequent GUI redrawing,
like GTK2 is already doing. Update every second though, don't enforce a
3 second limit. (fixes #967781)
* Only redraw visual progress if the currently shown fileinfo is updated.
(fixes #967781)
- (2005-09-16 - RAM)
* Now monitors the CPU usage and lower consumption if we detect overloads.
* Reduce amount of GUI refreshing done when CPU overloaded.
* Added chip.xpm icon, lighted on when CPU is overloaded.
* Optimized query routing via QRT.
- (2005-09-14 - RAM)
* Configure will now use "mkdir -p" over "install -d" if possible to create
directories (fixes bug #972777).
* Detect too large UDP messages explicitly to log their dropping in the
proper category.
- (2005-09-13 - RAM)
* Fixed file descriptor leak in uploads (bug #1285670).
- (2005-09-11 - RAM)
* Added robots.txt file to forbit all web crawlers from browsing us.
* The mechanism to add special shared files was made generic. The table
listing them is specials[] in core/share.c.
* Added property "bootstrap_debug" to monitor the bootstraping process.
* [GTK1] Added GUI settting for bootstrap_debug.
- (2005-09-04 - JA)
* [PARQ] Implemented option to always allow uploads which would take less
than a certain amount of seconds to complete.
* [PARQ] Show an astrisk in front of uploads which are given a quick
upload slot (time or size based).
- (2005-08-31 - RAM)
* Reduce the amount of time() and gettimeofday() system calls drastically.
This should reduce the kernel time used by GTKG.
- (2005-08-31 - JA)
* [PARQ] Added option to allow small uploads to always continue.
- (2005-08-30 - RAM)
* Revisited download selection logic when a GIV string is received.
* Improved tracing of the download selection logic for debugging.
* Added another banned GUID from Morpheus hosts.
* Added fast UTF-8 char decoder to try to reduce overhead of remappings.
* Validate the CHNK list from the fileinfo database, using the trailer
information if it is corrupted or missing.
- (2005-08-30 - JA)
* [PARQ] Added setting to allow more optimistic calculation of ETA.
default is TRUE.
- (2005-08-28 - RAM)
* Will now serve GTKG's favorite web icon when "/favicon.ico" is requested.
* Typo in metaconfig symbol prevented the use of sendfile() on platforms
that have it.
* The OOB-proxying ultrapeer would send back the local hits to the leaf
using the mangled MUID, instead of the original, surely causing the leaf
to discard the replies.
- (2005-08-27 - RAM)
* Adapt stalling threshold to the amount of upload slots configured.
* Reduced stalling TX buffer down to 1K.
* Count HTML and Gnutella browse host requests.
* Show HTML and Gnutella browse host request counts in upload stat pane.
* Don't allow dynamic upload slot allocation when uploads are stalling.
* Added internal GUID to each fileinfo, to be perused by downloads at
retrieval time, ensuring a download source is uniquely linked to a given
fileinfo.
* [GTK1] Added GUI setting for "parq_debug".
- (2005-08-24 - JA)
* [PARQ] Added parq_debug property for PARQ specific debugging
* [PARQ] Fixed bug where an upload got queued, with an ETA of 0s
and all upload slots where available
- (2005-08-21 - RAM)
* GTKG is no longer explicitly asking replying servents to skip XML in
query hits, since it can now show the XML.
- (2005-08-20 - RAM)
* [GTK1] Added 7 new GUI-settable debug levels.
* [GTK1] Added provision for displaying XML data from search results.
* [GTK1] Search results now show XML payload, if any.
- (2005-08-15 - RAM)
* Show GTKG's version, amount of files and total size shared in HTML browsing.
* If they advertise a host name in query hits, redirect an HTML browsing
to the qualified host name if it was directed to the IP address, so that
the links shown there have a longer lifetime.
* Allow the TX deflate layer to have its buffer size / flush / nagle params
configurable externally.
- (2005-08-14 - RAM)
* Added size of shared files within brackets in HTML browse-host output.
* Fixed buglet that caused no status to be displayed for completed uploads.
- (2005-08-13 - Hans)
* Include configure options for GNU TLS. GNU TLS is enabled when
found.
- (2005-08-10 - Hans)
* Include configure option for IPv6. Ask the user if this should be
enabled.
- (2005-08-04 - RAM)
* Make sure we abort the upload immediately if the shared file is no longer
present on the disk, especially when they are being queued for that
no-longer-existing file.
* Added full support for browse-host (server side): can now serve both
HTML and query hits.
- (2005-08-03 - RAM)
* Added "eager mode" to the TX stack to always have it serviced.
* Browse host is now honouring deflate and chunked encoding.
- (2005-08-02 - Hans)
* Initial optional D-BUS support. This code only supports D-BUS
0.35.2. Currently only 'started' and 'stopped' events are sent. The
gtkg-dbus-listener.py script listens for these events.
- (2005-08-02 - RAM)
* New TX "chunking" driver to be able to send HTTP chunked data.
* Both TX and RX stacks now use walloc() for memory allocation.
* Added tx_has_error() to check for TX errors.
* Added tx_close() with callback to be notified when transmission is closed.
- (2005-08-01 - RAM)
* Update the server IP when we get a GIV, and recompute the server's country
appropriately, with immediate GUI feedback.
* Try to compute a suitable upload filename for the SHA1 digest, especially
when PFS is enabled and we're given the digest of a file we downloaded
but chose not to share once completed.
* Was wrongly reporting "Already downloading that file" when the same host
requested two distinct files via PFS.
# v 0.95.4 2005.07.31 [stable]
- The last-byte download bug, where a download would not complete if
only the last byte needed to be downloaded, has been fixed.
- Preliminary browse-host support, allowing other servents to browse
the files that are shared. This is disabled by default.
- GTKG will detect online status again after temporary network failure.
- The .desktop file and application icons are now properly installed.
- Downloads are now sorting in a more logical way.
- Bug fixes in UTF-8 support.
- Doxygen documentation updates.
- Japanese and Spanish translation updates.
- (2005-07-31 - RAM)
* Added the "update" target to update the bogons and GeoIP database.
Requires wget and perl to be installed. (meant for developers only)
* Updated the bogons.txt and geo-ip.txt files by running "make update".
* Mention the "make update" step in the RELEASE guide.
* Re-instantiated step #7 in the RELEASE guide.
- (2005-06-29 - RAM)
* Was mistakenly thinking it was reading data from the network whereas it
simply had socket connections timeouting. Therefore, the "offline" status
was never activated after an Internet connection breakdown (fixes #1144460).
- (2005-05-23 - Hans)
* The gtk-gnutella.desktop file is now properly installed so that
GTKG can be started from the desktop menus.
# v 0.95.3 2005.05.22 [stable]
- Fixed a potential denial-of-service problem.
- Fixed OOB reply code which would lead to failed assertions.
- [GTK1] Show Enable option and Remove button in Filter editor again.
- Fixed inadvertent truncation of large files (> 4 GB).
- Compatibility fixes for 64-bit platforms.
# v 0.95.2 2005.05.10 [stable]
- GTKG generated up to four times more traffic than was needed between
GTKG Ultrapeer and GTKG leafs.
- Improved firewall status detection: if you are not firewalled then GTKG
is now less likely to claim that you are.
- Fix a build problem for some versions of Glade
- A few minor bugs fixed
# v 0.95.1 2005.05.06 [stable]
- Bitzi tickets are now persistently cached so that tickets are
available again after restarting GTKG.
- Improved Unicode support:
* The use of Unicode in queries now matches that of other Gnutella
clients. This will make it easier to search for file names which
contain non-Latin characters. At the time of release only
gtk-gnutella 0.95.1 and Limewire will respond properly to Unicode
queries.
* Files are shared with their names converted to UTF-8, and
downloads are stored with UTF-8 file names.
* Unicode support is now built-in, we no longer depend on the ICU
library.
- Search improvements:
* It is now possible to enter negative matches in search strings. If
you enter "blah -blubb -nada" as search string, results matching
"blubb" or "nada" are automagically filtered.
* The search filter allows filtering for files larger than 4 GiB and
you can also use suffixes like KB, KiB, MB, MiB etc.
- [GTK2] GUI updates:
* You can drag & drop items under Downloads->Files e.g., to pass
them to a audio/video player, picture viewer etc. Drag & drop is
dangerous when used on files from unknown sources. You have been
warned.
* GnutellaNet has a new item "Reverse DNS lookup" in its context
menu to perform a lookup of the peer's IP address.
* XML data contained in search results is shown in the results
details pane.
* The search edit field has been moved to the top.
* The Downloads pane was split into "Active Sources" and "Queue".
* Compatible with GTK 2.6.x and older versions.
- The GUI uses SI prefixes according to IEC 60027-2 (2000-11) Ed. 2.0
everywhere, so hard disk vendors won't fool you any longer.
- Compatibility fixes to allow compilation on more architectures,
including 64 bit architectures.
* Systems with a sendfile() that is not largefile compatible work
again. On platforms without sendfile() we now use mmap() for
improved efficiency.
- There are now two hostiles.txt, a system-wide ("global") and one in
the ~/.gtk-gnutella directory. So you only need to put private
additions into ~/.gtk-gnutella/hostiles.txt. These files are also
automagically reloaded on change, so you don't need to restart
gtk-gnutella to make the changes effective.
- Updated listings for geographic information, bogus addresses and
spam sites.
- Greatly enhanced stability as compared to 0.95 due to many bug
fixes. Other noteworthy bugs fixed are:
* gtk-gnutella as ultrapeer was not routing any searches iff uploads
had been disabled.
* Problems with the UDP/TCP port setting have been fixed (bug #1091827).
- German, Japanese, and Spanish translation updated.
- (2004-12-23 - RAM)
* Reject HTTP ranges for which start > end.
* If server gives us an inconsistent Content-Length compared to the total
file size found in Content-Range, abort the download and mark that source
as being bad.
* Use gm_slist_insert_after() to optimize new chunk insertion in list.
* Added file_info_check_chunklist() assertions right after modifying the
chunk list.
* Added contract in file_info_update() to require from < to.
- (2004-12-04 - RAM)
* Provide empty bitzi_init() and bitzi_query_byurnsha1() when they don't
have libxml2-dev installed. The GUI should disable the menu entry for
Bitzi searches as well.
# v 0.95 2004.11.27 [stable]
- Support for very old Gnutella features has been removed or deprecated
to keep the network healthy. Note that GTKG 0.94 is now considered a
deprecated servent in terms of Gnutella features. Every GTKG user
MUST upgrade to 0.95 as soon as possible.
- GUI updates:
* [GTK2] Enable drag and drop for magnet links
* [GTK1] Search results have less columns, and the hit details are now
displayed in a separate pane underneath.
* Visual progress indicator correctly shows newly downloaded
fragments, shows fragments currently available for download more
accurately, and active downloads are marked with arrows.
* The maximum amount of search results has been lowered to 1000.
Please use filters or more specific queries to find what you are
looking for if you get many search results.
* A detailed view has been added to the search results to show all
available information for a search result.
* The status bar will now give feedback about the contacted host caches.
* Gnutella node stats can now show how many bytes were sent/received.
* In the node pane, right-clicking now allows to configure which columns
should be displayed, just like in the search pane.
* More general statistics in the stats pane. It is possible to see TCP and/or
UDP traffic stats separately (for messages only, not flow-control).
- Bitzi support has been added to retrieve additional information on
possible downloads. See http://bitzi.com/ for details.
- The geographic location of hosts can now be shown courtesy of MaxMind.
- Recently developed features of the Gnutella network are now supported:
* High outdegree provides better connectivity between Gnutella hosts.
The maximum TTL in the network is now 4 and ultra nodes must maintain
at least a connection with 30 peers.
* Last-hop QRP between ultra peers.
* Dynamic querying support, allows selective querying of peers instead
of simply broadcasting the query. It is used for leaf queries and
for your queries when running as an ultra node.
* OOB (out of band) query hits lets other servents deliver search
results directly to you instead of going through the Gnutella network.
* OOB proxied queries, allowing direct hit delivery at the ultra node level
for queries emitted by legacy leaves.
* GTKG will now prevent firewalled hosts from running as ultra nodes.
* In "auto mode", GTKG will revert to leaf mode when uploads are stalling
at an abnormally high rate, indicating bandwidth is saturated.
- UDP is now also supported as a transport protocol in addition to TCP.
You may need to make changes to your firewall settings to take full
advantage of this. The UDP port used is the same as the one used for TCP.
- Firewall detection has been improved to include UDP firewalling detection.
- Clock skew computation for hosts not running NTP has been redesigned.
Also, GTKG will now automatically detect a locally running NTP.
- Japanese translation added.
- French and German translation updated.
- (2004-11-27 - RAM)
* Don't drop queries that have travelled more than our max TTL if they
are requesting OOB hit delivery and we are configured to honour that flag.
- (2004-11-26 - RAM)
* (fileinfo.c) Fixed static assert in READ_INT32 for Alpha, where time_t
is larger than 32 bits: we just need to know that we're reading into a
variable holding at least 32 bits.
* Renamed configure as configure.gnu for case-insensitive filesystems.
- (2004-11-22 - RAM)
* When sending non "alive" pings, include the "SCP" mark to get packed pongs.
* When replying to pings from Gnutella, give them "IPP" packed addresses if
they mentionned support for "SCP", even though the request comes via TCP.
- (2004-11-21 - Richard)
* Merge most of hache_remove into hcache_unlink_host and made the first
use the latter.
* [Gtk1] Added settings_gui_init_late() to restore split_pane positions after
main window is resized and visible.
* [Gtk1] Added viewport around result details.
- (2004-11-20 - RAM)
* Was only storing the freshest hosts from the cache, not the whole cache.
* Give priority to UDP host caches.
- (2004-11-14 - RAM)
* Don't remove a host from the cache whilst iterating over it.
* Generation of X-Features appended a trailing space after feature name.
* Don't send out GGEP "LOC" indication in pongs until they can configure
that from the GUI.
* Limited number of "normal" (legacy) nodes to which we can connect to 1 max.
* Only emit warnings about unknown / too numerous extensions when debugging.
* Adopted the same variable reply lengh on errors as in HTTP when bandwidth
is saturated. Added new error code 409 for "conflicts" and don't send out
connection "pongs" in the headers on all 403, 406 and 550 errors. Also
don't send them GTKG-specific headers if we determined they were not GTKG.
* Must shutdown OOB query hit delivery or we'll crash at shutdown time after
having freed the UDP socket.
* Added zlib_is_valid_header() to check for valid "deflated" buffer.
* [GTK2] Removed spurious g_assert() when no parent for SHA1-less results.
* Raised the max amount of alt-locs sent in GGEP "ALT" in query hits to 10.
* Added back accidentally removed sanity check during COBS decoding.
* Added extensive sanity checks on extensions marked as COBS and/or deflate,
to avoid parsing garbage as GGEP.
* Added GUI feedback in the statusbar about the web cache operations.
* Added UDP host cache support.
* Alternate between UDP host caches and TCP web caches when missing hosts.
* Regenerated po/gtk-gnutella.pot and friends.
- (2004-11-14 - Hans)
* Added Japanese translation (ja.po) from Daichi Kawahata.
* Updated .po files to include all files containing translatable strings
in the new directory layout.
- (2004-11-13 - RAM)
* As a leaf node, refuse to connect to "ancient" ultra nodes.
* Most vendors now send small ~4K max query hits: lower max hit size to 16K.
* The dynamic query layer expects much less results out of a SHA1 query.
* Added knowledge about GGEP "PATH" (unhandled for now).
* Make sure reserved word tables are lexically sorted, for binary search.
* Limit frequency of UDP ping replies.
* Limit frequency of TCP/UDP crawler replies.
- (2004-11-12 - RAM)
* Properly echo UDP crawler's ping MUID in the pong.
* LimeWire added the user-agent of the node replying at the tail of the
user-agent vector in the UDP crawler pong.
* Made GGEP parsing more robust, in case we parse garbage: avoid creating
needless extensions. Limit GGEP IDs to ASCII strings.
* Forgot to emit the X-Dynamic-Querying header to signal we're issuing
dynamic queries.
* Trim down TTL of queries coming from "older" hosts not performing dynamic
querying if the hops+TTL is larger than the TTL at which we're broadcasting.
* Set default for max_ttl to 4. Cannot set a my_ttl greater than 4.
* Added knowledge about GGEP "BH" and "CT" (unhandled for now).
* Search results now ignore unknown GGEP extensions in tags, thereby avoiding
display of "funny" characters in tag.
* Handle older LIME/21v1 and LIME/22v1 messages (older specifications of
the push-proxy requests, still used by outdated servents like GnucDNA).
- (2004-11-11 - RAM)
* Refactored decoding of GGEP extensions: this is now done transparently
for compressed / COBS encoded extensions. All accesses to payload length
and the actual (decoded) payload must now be done via routines.
* Got rid of false plural forms "source(s)", "upload(s)", etc...
- (2004-11-10 - RAM)
* Fixed "completion test" in incremental deflater.
* When we don't have leaves, the UDP crawler pong builder would fail.
- (2004-11-09 - RAM)
* Forgot to alter host_count when moving hosts between caches.
* Added support for LimeWire's UDP crawling.
* New properties "pcache_debug" and "udp_crawler_visit_count".
- (2004-11-08 - RAM)
* Use MEM_ALIGNBYTES to let Configure compute the proper memory alignment.
* Moved STATIC_ASSERT() to "common.h".
* Make sure atom's arena is properly aligned.
* Now parses GGEP extensions in "fat" pongs and saves them in the pong cache.
* Emit "fat" pongs for ourselves unless we're replying to an "alive" ping.
* Replies to UDP host cache pings ("SCP") with "IPP" extension in pongs.
- (2004-11-07 - Hans)
* Show arrows in visual progress to indicate downloads in progress more
clearly.
- (2004-11-07 - RAM)
* Allow zlib_deflater to perform deflation into a supplied buffer.
* Keep track of the amount of input we see for incremental deflation.
* Allow COBS to perform streaming operations.
* Fixed bug in COBS decoding.
* Added the "ggep_debug" property.
* New streaming interface to generate GGEP extensions replaces older one.
- (2004-11-01 - RAM)
* Integrated GTK1 patch from Alex to display feedback on Bitzi query queuing.
* Don't kick out nodes for relaying high TTL routed messages.
- (2004-10-31 - RAM)
* Changed the interface for hashlist iterators.
* Move bogons and hostiles closing after host_close() since the cache can be
updated during the closing, and the cache now uses bogons and hostiles.
* Periodically sync host cache to disk if dirty.
* Converted host cache to the use of hash lists, and added save routine.
* When inserting a host in the busy/unstable/timeout caches, remove it from
the other host/ultra caches.
* Don't add bogons/hostiles to the cache.
* Disallowed the choice of "legacy mode" as peer mode.
- (2004-10-27 - RAM)
* New property "ntp_detected" to track whether we detected NTP or not.
* Raised default TCP RX buffers for downloads and gnet to 64K and 16K.
* When they say they're running NTP, trust them as far as the clock skew
goes, but don't advertise NTP unless we detect it.
- (2004-10-26 - RAM)
* Optimized SHA1 computation (~10% gains with -O2, 20% with -O0 on a P3).
- (2004-10-23 - Richard)
* [Gtk1] Removed autoselection controlling. Now we only autoselect the whole
branch.
* [Gtk1] Press "del" to discard selected search results.
- (2004-10-20 - RAM)
* Record incoming activity to avoid marking a node "offline" too aggressively.
* Save position of the "vpaned_results" vertical pane when exiting.
* Save position of the "hpaned_filter_main" horizontal pane when exiting.
- (2004-10-19 - Richard)
* [Gtk1] Added "Configure columns" to nodes pane
* [Gtk1] [Gtk2] Removed nodes column configuration checkboxes
- (2004-10-19 - RAM)
* Added workaround for GnucDNA bug in BYE messages.
* [GTK1] Added bottom information for selected hits.
Removed Host, SHA1 and Speed columns for search results.
This now matches the GTK2 font-end presentation.
- (2004-10-18 - RAM)
* Fixed small memory leak in core/uploads.c.
* Remember IP of stalling uploads for a while, via the new "aging" table,
so that we don't increase our stalling counter too rapidly when uploads
to the same host keep stalling.
- (2004-10-17 - RAM)
* When running out of leaf slots, kick non-sharing leaves or leaves preventing
querying via hops-flow.
- (2004-10-16 - RAM)
* Added bogons.txt and geo-ip.txt databases.
* Fixed inverted logic test, causing spurious "got metainfo in filecache"
warnings and not doing the proper things.
* GUI properties capturing column positionning no longer rely on hardwired
constants but use the definitions from ui/gtk/columns.h.
* Added columns showing the country codes of the hosts (labeled "Loc").

- (2004-10-03 - RAM)
* Added pre-send checking hook to the PDU message descriptor.
* Added the tx_flush() operation to force buffer flushing, if any.
* The "Time Sync" messages now use the pre-sending checking hook to write
an accurate clock timestamp.
* Message queue now rely on the pmsg_check() pre-send hook to determine
whether a message can be sent or not.
* When writing a control message, make sure TX buffers are flushed, if needed.
* Alive pings now use the pre-send checking hook to ensure that only the
pings recorded last are sent on a given connection.
* Fixed memory leak in alive ping management.
* Switch to TCP if they don't answer our "Time Sync" requests via UDP.
* Added auto-detection of NTP running on local host.
* Tooltip for "Host runs NTP" now mentions GTKG will auto-detect NTP.
* Correct remote clock seen in the Date HTTP header by the amount of time
necessary for the headers to travel back (estimated from HTTP roundtrip).
* Better clock skew computation and update algorithm, based on statistics.
* The Date HTTP header was not using clock skew to correct time.
- (2004-09-29 - RAM)
* Added "Time Sync" vendor messages.
* Accept clock synchronization from same IP if the precision is better.
* Count unclaimed and partially claimed OOB locally-generated hits.
* Show TCP/UDP round-trip times as determined from "Time Sync" messages.
- (2004-09-28 - RAM)
* The header to emit is X-Push-Proxy now, not X-Push-Proxies.
- (2004-09-27 - RAM)
* Assume the majority of servents will now understand bounded Range requests.
* Leaf node's TX buffer size was too small for decent output.
* Count GIV callback requests we get.
* Count QUEUE callback requests we get.
* Ensure UDP socket gets a large RX buffer size, to avoid dropping datagrams
if we're busy and we can't process them yet.
* The "improbable SHA1" detection now recognizes trivial sequences.
* Check GGEP "H" and "u" in query hits for improbable SHA1.
- (2004-09-26 - RAM)
* When debugging, always show bad SHA1 and old-style SHA1 in the logs.
* Force "auto mode" when they run as ultra mode and get firewalled.
* When bandwidth is not capped, adjust the maximum used to show the
used bandwidth so that sudden bursts don't cause subsequent display
to show negligeable percentage.
* Ensure we see either the yellow or the red bomb icons, but never the two
at the same time.
* Don't decrement TTL during routing if it was 0.
* Always send a PONG with personal information, even when the local IP
address is unknown.
* Raised max # of downloads to 5000, default auto-retry timeout to 300 secs,
and default connecting timeout to 60 seconds.
- (2004-09-25 - RAM)
* Now assumes that all servers support the /uri-res/N2R? file requesting.
We don't really want to download anything from older servents anyway.
* Ignore improbable SHA1 made of identical bytes, either in their base32
encoding or in their binary form.
* Count the GTKG queries and requeries we see, as well as queries for which
we can reply using GGEP "H" for SHA1.
* Tell them every 5 attempts that they're banned instead of 10.
* Revisited the computation performed to determine whether we can be an
ultra node: only use the EMA of the outgoing b/w if they have running
uploads. Lowered b/w requirements to only 128 B/s per connection.
* Account for "uploads_stalling" when determining whether we have enough
b/w to stay an ultranode.
* Double time spent as a leaf node in auto-mode each time we switch back
to leaf mode.
- (2004-09-24 - RAM)
* Fixed warning about badly configured proxy, which must be emitted only
when a proxy is chosen.
* New "H=xxx" statistics for nodes, enabled when dups/bad etc... are
configured for display, showing the amount of messages bearing an
hostile IP address which we get from the node.
* Tell them in the search statusbar when the search was stopped.
* Don't show the origin IP address of UDP-delivered hits if it matches the
one held in the query hit.
* Append "alt" to query hits bearing alt-locs.
- (2004-09-23 - RAM)
* Keep track of whether we receive solicited UDP traffic.
* Send an UDP ping to our peers when we connect and we're not sure whether
we can get UDP solicited traffic.
* Ensure we can receive solicited UDP traffic before advertising OOB hits.
* New property "uploads_stalling" to track abnormal upload stalling.
* New property "recv_solicited_udp" to determine whether we can perform
UDP hole punching.
* [GTK1] [GTK2] Will now show a warning if uploads are stalling abnormally,
and a firewall with a green hole if we can perform UDP hole punching.
* Count UDP hits bearing a different IP address from where they're sent from.
* Don't count the IP as alien if the hit's address is that of a private
network, in case the servent is firewalled.
* Have shell announce the program's version.
* [GTK1] Frame where icons are displayed will now properly shrink when an
icon is hidden.
* Named frame where icons are displayed to be able to shrink it.
* Setting of OOB queries is now an "expert" frame.
* Don't send PUSHes too often. Just because we don't get a reply immediately
does not mean the PUSH is not travelling its way.
* Show IP address of UDP-delivered hits.
- (2004-09-21 - RAM)
* Added dh_would_route() for the OOB-proxying layer to be able to determine
whether the hits it would claim would be delivered to the leaf or
thrown away by the dynamic hit layer.
* Deleted obsolete code in download_push_insert() and download_push_remove():
select_push_download() has already all the logic to grab the proper
download when a GIV is received.
* Let dynamic query know about unclaimed OOB-proxied hits.
* Raised timeout for "Query Status Response" to 30 seconds.
* Don't send dynamic query to another node if we already queued but not
sent 3 queries to other nodes.
* Send "Query Status Request" as a control prioritary message.
- (2004-09-20 - RAM)
* Fixed OOB-proxy routing logic to no longer use the routing table: we keep
the ID of the leaf node originating the query around.
* Don't claim UDP results fro OOB-proxied query when the leaf node is
in TX flow-control.
* Don't check for TTL=0 on hits for OOB-proxied queries.
* Can only check the IP of neighbours setting the OOB flag on queries, since
the UDP port can be different from the TCP port.
* Was not displaying instantaneous RX traffic rate for the pseudo UDP node.
* Count the amount of OOB hits received for OOB-proxied queries.
* Count the amount of queries we see with the OOB flag set.
* Improved delivery of query hits to searches by making it faster to locate
a search given a MUID.
* Raised the timeouts for dynamic querying slightly, to see if we can get
less traffic overall and less results during lingering period.
* Monitor the hostiles.txt file and reload it automatically if it changes
(closes RFE #1003129).
- (2004-09-19 - RAM)
* Automatically demote an Ultrapeer that appears to be TCP-firewalled.
* Fixed routing debugging logs.
* Added core -> UI bridge routine guc_statusbar_warning().
* New property "routing_debug" to control debugging for message routing.
* Warn them in the statusbar if they attempt to choose a non-leaf mode
and they are firewalled.
* [GTK1] [GTK2] Added GUI mapping for new "routing_debug" property.
* Implemented OOB-proxying of queries, when running as ultranode.
* Ammended the routing policy of queries to account for duplicate OOB-proxied
queries that would differ only in the IP:port of their MUID.
* New property "proxy_oob_queries" to control OOB-proxying by the ultranode.
* New general statistics: GNR_OOB_PROXIED_QUERY_HITS,
GNR_QUERY_OOB_PROXIED_DUPS and GNR_OOB_PROXIED_QUERIES.
* [GTK1] [GTK2] Added GUI mapping for new "proxy_oob_queries" property.
- (2004-09-18 - RAM)
* Must not reset n->socket after processing data from UDP node, since we
can issue an UDP message at any time, therefore the n->socket must stay
set at all times. Removed node_udp_release().
* Fixed binary search for vendor messages: was assuming there would not
be duplicates with only the version number changing in the table, but
this was forgotten and the table lists messages with different versions
as different entries. Caused it to not process UDP connect back correctly.
* Added more search statistics at the bottom of each search window.
* Drop OOB queries with a bad "return address" i.e. queries coming from a
neighbouring node and whose IP:port for return does not point back to the
issuing node.
* Strip OOB flag on queries whose return adddress is a private IP.
- (2004-09-15 - RAM)
* Was not accounting received queries and query hits for the UDP node.
* If they remove the pseudo UDP node, it will disable UDP.
* Handle GTKG/7v2, where GUID of the ping is taken from the MUID instead
of from the payload.
- (2004-09-13 - RAM)
* RX dropped packets are now accounted for in gnet_stats_count_dropped().
- (2004-09-12 - Hans)
* Update visual progress code to avoid flickering and fix small problems
with the code.
* Create separate event for available ranges updates for more efficient
handling of fileinfo information.
* Provide initial version of a manual in doc/manual. The manual is in
DocBook XML format. Currently it is only an outline. Please commit
a placeholder or let me know if you would like to work on a specific
part.
- (2004-09-11 - RAM)
* Will now send queries marked for out-of-band hit delivery.
* Out-of-band hit delivery is now enabled by default.
Changed tooltip comment for property to explain the user benefits.
* Tag hits received from UDP in search results with the string "udp".
* Strip OOB flag for leaf queries that also advertise they're firewalled.
Chances are that if they are TCP-firewalled, then they're UDP-firewalled
as well.
* Added GUID generation for OOB queries.
* Forgot to arm the timer for monitoring absence of unsolicited UDP traffic.
* Update RX traffic size for the pseudo UDP node.
* Fixed statistics bookkeeping for dropped UDP messages.
* New properties "show_gnet_info_tx_wire" and "show_gnet_info_rx_wire"
to govern display of TX and RX bytes, as sent/read from the wire.
* [GTK1] [GTK2] Can now ask to display bytes sent/read from the wire for
each node connection.
- (2004-09-10 - RAM)
* UDP listening is now enabled by default.
* Strip OOB flag of OOB queries from leaves where the IP:port encoded in
the GUID of the message does not match the leave's ones.
* Dropped stats did not update the TCP-only and UDP-only stats.
* Smarter UDP-firewall (unsolicited traffic) detection: now keeps track of
the IP to which we sent datagrams for 2 minutes to avoid falsely marking
the node as not-firewalled when we receive data from those IPs.
* Added node_gnet_ip() and node_udp_get_outq().
* Will now drop UDP messages coming from hostile IP addresses.
* Added an "alive_ping" object to the pseudo UDP node for proper display
of round-trip stats for that node.
* Adapted the query hit generation process to OOB hits, since we must not
deliver those immediately but need to buffer them instead.
* Can now honour the OOB flag in queries and deliver hits out-of-band.
* Added support for vendor messages LIME/12v2 and LIME/11v2, delivered via
UDP to negotiate delivery of OOB query hits.
* New property "query_debug" for debugging queries.
* GUI was not reporting Gnet b/w properly: it needs to sum the TCP and UDP
traffic shapers since allocated b/w is halved between those two.
* [GTK1] [GTK2] Added spinbutton for "query_debug" setting.
* Skip messages that cause an error during UDP write, but continue processing
remaining messages.
* Allow EINVAL as a legitimate error cause for sendto(), since apparently
linux returns this for weird IP addresses, like "0.76.207.219".
- (2004-09-08 - RAM)
* Moved query hit generation from share.c to new qhit.c.
* Changed process for generating query hits: the matching code now generates
a list of hits, and that list is then traversed to generate the necessary
query hit messages.
* Changed frequency of inter-UP QRP exchanges: now performs one update every
5 minutes instead of one every 90 secs.
- (2004-09-06 - RAM)
* Added UDP bandwidth schedulers for Gnet traffic, taking half the bandwidth.
The other half being given to the TCP Gnet traffic. Both auto-steal their
unused bandwidth, if necessary.
* Added new UDP message queue.
* The pseudo UDP node is now advertised and shown in the GUI.
* Extended the wrapped I/O with sendto().
* Show pseudo UDP node in GUI as being of type 'P'.
- (2004-09-04 - RAM)
* Fixed typo causing aggregated TCP+UDP stats to be returned when TCP stats
were requested.
* Fixed the "crash when closing search" bug.
* Was accounting stats for HSEP message exchanges as "unknown"!
* Reply to an UDP ping with an UDP pong.
* Keep statistics about UDP traffic.
* Found the origin of the "race condition" that caused assertions to fail
in dh_pmsg_free(). We just can't assert at that point.
- (2004-09-03 - RAM)
* Keep and allow retrieval of TCP and UDP stats, separately or in
aggregated form.
* New property "gnet_stats_source" to select the TCP/UDP source for stats.
* Added gnet_stats_tcp_get().
* [GTK1] [GTK2] Message stats can show TCP-only traffic, UDP-only, or both.
* [GTK1] [GTK2] Added icons showing TCP-only and UDP-only firewall status.
* Firewall status can now have 4 states: fully firewalled, TCP-only,
UDP-only and not firewalled. The UDP firewall is shown only if UDP is
enabled.
- (2004-09-02 - RAM)
* Implemented dynamic querying for local queries, when running as an
ultra node.
- (2004-09-01 - RAM)
* Made sure we keep the route on GTKG/21v1 reception, and that we simply
remove the new NODE_F_PROXIED flag on the node.
* Lowered the default maximum amount of results shown from 5000 to 1000 to
both save on memory and incite users to setup filters or emit more specific
queries.
- (2004-08-31 - Hans)
* Visual progress indicator now correctly shows previous and newly
downloaded chunks.
- (2004-08-30 - RAM)
* Message queue now maintains whether queue is within the warn-zone range
(between hiwat and lowat) to update node's flag as soon as the condition
changes.
* Added support for GTKG/21v1 "Push-Proxy Cancel" vendor message.
* Show used charset at startup time.
- (2004-08-29 - RAM)
* Added count of bytes/packets queued to be able to monitor the amount of
bytes/packets dropped whilst in the TX queues. New columns "queued" and
"gen. queued" will show the queued bytes/packets from received and locally
generated packets respectively. Column "generated" renamed "gen. sent".
* Check for OOB queries in node_can_send(), since we need to forward them
regardless of whether there exists a route for replies.
* Split huge route_message() routine in smaller parts.
* When we get unsollicited guidance info for a dynamic query, there is no
need to query the leaf before proceeding with the next ultra node.
* Vendor message table was accidentally not sorted, messing the binary
search logic and causing valid messages to be ignored.
* Now sends BEAR/12v1 "query status response" as a prioritary message.
* Leaf nodes will now send unsollicited BEAR/12v1 to their ultranodes
reporting kept results each time they get new query hits from the network.
- (2004-08-28 - RAM)
* Allow forwarding of queries and pushes that were already seen with a
lower TTL, but don't process them again.
* Raised max for "reserve_gtkg_nodes" to 90 and lowered min for
"unique_nodes" to 10.
* Forgot to tie the GUI button for "convert_spaces" to the property, hence
setting in the GUI had no effect.
- (2004-08-28 - Hans)
* Move available ranges (blue line in visual progress) code from the gui
to the core.
- (2004-08-18 - RAM)
* (move.c) Fixed stupid floating point exception on a debug message
when elapsed == 0
* Removed dependency between file.c / sockets.c and ban_reclaim_fd().
- (2004-08-16 - RAM)
* Added new properties for UDP support: "udp_debug", "enable_udp",
"is_udp_firewalled", "process_oob_queries", "send_oob_queries".
* Added support for UDP firewalling detection.
* Can now process incoming UDP Gnutella messages as if originating from
a "fake" UDP node.
* Will now recognize incoming UDP ping bearing our GUID as a sign that
we can receive unsollicited UDP traffic.
* pcache_pong_fake() now takes only ultranode addresses.
* Make sure we never route queries and query hits received from UDP.
* Added support for UDP sockets.
* Special-case display of vendor code with all zeroes as "null".
* Added support for GTKG/7v1 "UDP Connect Back" vendor message.
* [GTK1] Updated GUI to be able to configure UDP, OOB querying, and
debug levels.
* (settings_gui.c) Shuffled to move the propery table near the end to
avoid pre-declaration of most callbacks. Added UDP configuration
and debug level settings.
- (2004-08-14 - RAM)
* Added gmsg_infostr_full_split() and gmsg_infostr_full() that can
add extra information when logging vendor messages.
* New vmsg_infostr() to extract vendor message information for logging.
* (qrp.c) Fixed memory leak.
* Accept BYE, HSEP and vendor messages with TTL=0 or TTL=1.
* New properties "vmsg_debug" and "search_debug".
* Always reply to handshaking ping (first ping we accept) with personal info.
* Don't revitalize route entries for leaf nodes but for the PUSH routes we use
when we're sending PUSH messages.
* Parse (but ignore for now) the "features supported" NULL/10v0 message
which supplies extra capabilities without negotiating them via handshake
headers.
* If leaf queries us with OOB hits delivery and does not support guidance,
strip the OOB flag from the query to be able to monitor the hits they get.
- (2004-08-13 - RAM)
* Removed the "unrequest reply" drop reason, replaced by "no route". It was
used only by query hits, whilst "no route" was used only by "pushes".
* Changed the way the routing table is organized to be able to remember
active routes (for query hits or pushes) longer than unused ones.
- (2004-08-12 - RAM)
* Increased routing table size to keep at least 30 minutes of traffic.
* Handle query hits we don't route, in case they have alt-sources we
could peruse.
* If query hit is dropped for flow-control reasons, account it as such.
- (2004-08-10 - RAM)
* Ensure "size != 0 => file_size_known" in fileinfos and create_download().
* Added parsing of GUID for queries with OOB query hit delivery.
- (2004-08-09 - RAM)
* Whith leaf-guided dynamic queries, adjust the number of kept results when
comparing to the maximum allowed, since leaves return the total amount
of results, not the ones received from just our connection.
* Fixed assertion that forgot to account for kept results.
* No longer drop node for sending/relaying messages with TTL=0: simply
ignore the bad message and go on.
* Now try to support BearShare and its great (not!) idea of acking an
alive ping with a TTL=0 ping!
* Make sure we always log something in debug mode when seeing a bad packet.
* Send PUSH requests at the highest TTL we can, i.e. hard_ttl_limit and
not max_ttl which is only for broadcasted messages.
* Use ping-pong roundtrip times to guess a relevant timeout for the
"Query Status Request" message sent for leaf-guided dynamic queries.
- (2004-08-08 - RAM)
* To allow safe data access to the free routine invoked for extended messages,
we must not unref the data before calling the free routine in case we were
holding the last reference to those data.
* Refactored the single monolithic message_array[] routing table into
a dynamic set of smaller chunks, to ensure we will keep routes at least
20 minutes.
* Fixed unfortunate bug in token.c that prevents an older version from
validating the token from a more recent version if the recent version
has more keys to compute the level with than the older can check for.
* Fixed assert failure on reception of query hits that is handled
locally but not routed.
* Added support for leaf-guided dynamic queries (client and server sides).
- (2004-08-07 - RAM)
* Forgot to call node_inc_sent() when sending a queued message, as opposed
to one immediately written at mq_putq() time.
* Added "n->last_tx" and use that when detecting activity timeouts, making
sure that there is something in the queue (or it would not be updated).
* Reverted changes made to node_reserve_slot() and node_avoid_monopoly()
which tried to make a distinction for UPs between incoming and outgoing.
- (2004-08-06 - RAM)
* Fixed some of the "file_size_known" madness.
* Whether the file size is known or not is now persisted in the fileinfo,
as the "FSKN" attribute in the ASCII file, and as part of the version 5
binary format in the file.
* Show "no size" when the size is unknown, shorter than "unknown size".
* Fixed qrp_route_query() to send query to all non-QRP aware UPs if TTL=1.
* Fixed improper routing of TTL=1 queries, which could be sent twice to
QRP-capable nodes: once if the QRP matched, and once via regular broadcast!
* Make dynamic queries that stopped linger for a while to see how many
extra results we get due to node latencies. New statistics track the
amount of extra results we get that way.
* Don't send a TTL=1 dynamic query to a host whose QRP says it won't be
able to match.
* If a QRP-capable UP did not send its table yet, forward it everything.
* Introduced the "dynamic query hit" algorithm: this actively monitors
hits we relay, keeps track of how many hits we sent and can decide
to drop hits if we're in flow control or relayed too many hits already.
* New "dh_debug" property.
* Drop query hits with 0 results.
* Have search_results() indicate to caller the amount of hits held in the
query hit it parsed.
* The flow-control flag can now show 'D' if we're not in flow-control
yet but the queue is more full and bears a greater delay for sent
messages (queue size above the low watermark).
- (2004-08-05 - RAM)
* Implemented dynamic querying. For now, it's only plugged for leaf queries.
* Fixed re-entrance problem when an event was rescheduled before the current
trigger time by another event that fired.
* Added 5 general statistics about dynamic queries and their status.
* Added new "dq_debug" property for debugging dynamic querying.
* Emit and parse headers for dynamic querying.
* Added hack for LimeWire, emitting the garbage it wants from leaves to
consider them good.
It is a bug from LW to require those meaningless headers from leaves.
* Enhanced pmsg to have support for free routine callbacks.
* It is now possible to mark messages as being sent, for checking in the
free routine afterwards.
- (2004-08-05 - Jeroen)
* When avoiding vendor monopoly, make a difference between outgoing and
incoming connections.
- (2004-08-05 - Jeroen)
* Commited some stuff for G2 support, to avoid I lose it again.
- (2004-08-03 - RAM)
* Updated hostiles.txt from BearShare's list.
* Removed spurious and wrongly placed call to header_features_generate()
from http_async_build_request().
* The "up_req_*" properties were wrongly saved in the config file. Since
they're transient and dynamic, it's useless to persist them.
* New "up_req_enough_conn" property to track whether they configured enough
peer connections to maintain to become an ultra node.
* Show whether they configured "Enough min # of connections" to be
auto-promoted an ultra node.
* New flag "Z" for connections that compress both TX and RX. "T" is shown
when only TX is compressed, "R" is shown when only RX is compressed.
* New flag "X" indicating whether we sent our last-hop QRP table to the remote
ultra node. The "Q" flag in that case indicates whether we received the
last-hop QRP from the remote node.
* Added support for high outdegree and last-hop QRP between ultra nodes.
- (2004-08-02 - RAM)
* Converted getline.c and http.c to doxygen-style comments.
* New IO_SAVE_HEADER flag to instruct the ioheader parsing layer to
save a copy of the header text, as it was received.
* Forward queries with TTL=0 to leaves, as QRP tables permit.
* Added specifications for inter-UP QRP, dynamic queries and leaf-guided
queries.
- (2004-08-02 - Hans)
* Show gray progress bar when the file size of a downloadable file is not
known.
- (2004-08-01 - RAM)
* Made gchar_to_ip_strict() return host byteorder IP addresses, to be
consistent with gchar_to_ip().
* Updated styleguide: in files using doxygen comments, the function name
must now be put at the very beginning of the line to have it stand out.
* Added new fields in fileinfo trailer: CTIM the creation time and NTIM
the last time when we got a new source.
- (2004-07-24 - Hans)
* Make 'Purge' button on the 'Files' tab inactive when file has been
completely downloaded. Fixes #922920.
- (2004-07-19 - TNT)
* Added option 'ALL' to the remote shell command 'HORIZON'. This option
will output the total horizon size as usual (including non-HSEP nodes) and
will then output the horizon size of each directly connected HSEP node. May
come handy for checking/debugging purposes.
- (2004-07-15 - Jeroen)
* Enabled drag and drop for the GTK2 interface for magnet links.
- (2004-07-14 - Jeroen)
* Added initial support for downloads with unknown size. Patch from emile
- (2004-07-13 - RAM)
* Make sure PONG messages hold a reasonable number of files, i.e. detect
servents that did not encode the value correctly by advertising an
absurdly large number of files. Then try to fix the total size shared.
- (2004-07-10 - Richard)
* [Gtk1] Replaces GtkFrame around progress indicator in fileinfo pane
with a GtkViewport
* Removed gui_update_all()
* Renamed gui_update_global() to gui_general_timer()
* Moved gui timer calls from gui_update_global() to main_gui_timer()
* Added doxygen support to: gui.c search_gui_common.c
* Moved gui_add_targetted_search() as search_gui_add_targetted_search()
to search_gui_common.[ch].
# v 0.94 2004.07.10 [stable]
- GUI updates:
* File info pane renamed to downloads
* Downloads pane renamed to sources
* Progress of a download can now visually be showed. This will show which
fragment of a file was downloaded, which fragment gtkg currently is
downloading and which fragments are availalbe on the gnutella network.
* Uploads and download sources pane now contain a visual progressbar.
* GTK2 can now be resized smaller then 933 pixels width.
* Search results now include an extension column so you can sort by
extension if needed.
- HSEP included, this will give you an estimation of the horizon size. This
includes the number of files and the total size of all files on the network.
- If no default port was specified, gtkg will now bind to a random port and
will use that port from that point.
If you are behind a firewall and routed a port to gtk-gnutella, please check
gtk-gnutella still runs at the port you want it to run!
- Will parse up to 150 hosts in a gwebcache reply to bootstrap from.
- New hostcache to make gtk-gutella faster connect to the network.
- Dutch translation updated.
- German translation updated.
- Spanish translation updated.
- French translation updated.
- Hungarian translation updated.
- (2004-06-25 - Richard)
* Reverted changes in hcache.c from last commit. Instead made those changes:
* No longer call hcache_remove_all() from hcache_free().
* Made hcache_free() fail if hostcache is not empty.
* Fail if for some obscure reason hosts are added during hcache_close. This
can normally only happen if we are multi-threaded, which we are afaik not.
* Check that hostlist and host_count are in sync when hcache_remove_all() is
done.
- (2004-06-24 - Richard)
* Fixed segfault in hcache.c on shutdown due to accessing hostcaches
which had already been freed at that point.
(Thanks to Clayton Rollins for the backtrace)
- (2004-06-23 - Richard)
* [Gtk1] Ported "extension" column in search results from Gtk2.

- (2004.06.16 - JA)
* Hopefully fixed phantom downloads due to PARQ callback
- (2004.06.14 - TNT)
* Changed HSEP implementation to also send out information about all
our non-HSEP neighbors (PONG-based library size). This should make the
horizon stats more accurate, even though we don't know anything about
what non-HSEP neighbors see as their horizon.
* [Gtk1] [Gtk2] Changed statusbar and gnet stats panel to also include
horizon information about all non-HSEP neighbors. The horizon stats
on the gnet stats panel are now updated every 2 seconds.
* Updated .pot/.po file generation to include all source files that contain
translatable strings.
- (2004.06.10 - Hans)
* The blue line in visual progress indicating the bytes available on the
network now also takes servents sharing the full file into account.

* [Gtk1] [Gtk2] Use more efficient handling for size of visual progress
indicator and remove obsolete code.
- (2004.06.08 - Richard)
* Use hash table instead of list for faster lookup in node_is_connected()
and node_host_is_connected().
* Split up gnet.h into several files for better readability.
All are included from gnet.h.
* Changed algorithm for quick-connecting to utilize only up to
PROP_QUICK_CONNECT_POOL_SIZE connections instead of using
them additionally to the maximum number of connections.
* Changed large parts of the host cache code. We now have seven host caches
and we can get stats for them.
* Adjusted default hostcache capacities.
* Removed "unstable ip" code from nodes.c. This is now handled in hcache.c.
* Started with doxygen support.
* Added file_config_open_append to file.c. Needed by new hostcache code.
* Moved host_hash, host_eq and host_cmp as public functions to hosts.c.
* Made host_is_valid(ip,port) a define. The function is now ip_is_valid(ip).
* Pongs from hosts that are marked bad in the host cache are no longer added
to the recent pong cache.
* [Gtk1] [Gtk2] Minor layout fixes which were not in the last commit.
* Manually added new files to the build files. Somebody who can regenerate
the build files and known about the package files has to double-check this.
- (2004.06.07 - Richard)
* [Gtk1] [Gtk2] Added hostcache panel.
* [Gtk1] [Gtk2] Added horizon stats labels to the statusbar.
* [Gtk1] [Gtk2] Made quick-connection pool size configurable.

* [Gtk2] Added horizon stats table to gnet stats pane. Rearranged
and optimized pane layout.
- (2004.06.04 - Jeroen)
* Fixed compilation error due to removed property
- (2004.06.03 - Jeroen)

* [Gtk2] Activated 'fixed_height_mode' for the nodes TreeView.
* [Gtk1] [Gtk2] Made the search retry timeout an expert setting.
* [Gtk1] [Gtk2] Made the autoselection feature an expert setting.
* Renamed some of the autoselection properties to assure they are
reset an a new start.
* [Gtk1] [Gtk2] Changed autoselection policy and moved relevant code
to search_gui_common.c
* [Gtk1] Reducted number of times results are resorted in
download_selection_of_ctree().
- (2004.04.18 - Hans)
* [Gtk1] [Gtk2] Fix several bugs in visual progress code.

* [Gtk1] Added toolbar style selection combo to gui config pane
* [Gtk1] [Gtk2] Added icons for PROP_FILE_DESCRITOR_SHORTAGE and
PROP_FILE_DESCRIPTOR_RUNOUT
* Updated filter.xpm
* [Gtk1] [Gtk2] Tried to fix memory lead in visual progress indicator.
Small leak is still reported but probably due to the gui never being
actually destroyed.
* [Gtk1] [Gtk2] Adjusted colors in progress indicator.
- (2004.04.12 - RAM)
* (gwcache.boot) Re-initialized from GhostWhiteCrab's verified peer list.
* Don't publish our IP to web caches if we're a normal (legacy) node.
* Removed connection to GWC at startup. Wait 8 hours to do that!
- (2004.04.11 - RAM)
* Renamed parq_is_banned_source() into parq_banned_source_expire() and
have it return the expiration date of the banning.
* When GTKG rejects an upload with "403 ... removed from PARQ", it will
include a Retry-After header to indicate the banning limit, since
further requests from the host will be back-holed.
* When downloading, treat GTKG's "403 ... removed from PARQ" specially,
looking for a possible Retry-After to know when retrying will be possible.
- (2004.04.11 - Hans)
* [Gtk1] [Gtk2] Fileinfo pane now contains a visual indication of the
download progress for the selected file.
- (2004.04.10 - RAM)
* Will now parse up to 150 hosts in hostfile replies.
* Change webcache everytime we want to perform an action, in case we
hit a bad cache that ignores our updates silently or replies with
bad (static!) data.
- (2004.04.07 - RAM)
* Added my own web cache, now that I run GhostWhiteCrab/0.1.
* Only write readable filenames in done.sha1.
- (2004.04.02 - RAM)

* Removed default cache on raphael.manfredi.free.fr, which was erased.
- (2004.03.28 - RAM)
* [GTK1] Fileinfo filtering now also applies the regexp to fileinfo aliases.
* Compile glade-generated files last, to save time when there is an error
elsewhere.
- (2004.03.26 - Richard)

* Comment out GTK_GNUTELLA_DIR export in run script.
- (2004.03-17 - Richard)
* [GTK1] Slight layout change in the fileinfo pane.
* [GTK2] Purging of multiple files is now possible.
- (2004.03.15 - RAM)
* [GTK1] Added anti-crash countermeasures for memory corruption in GUI
search results data. Does NOT fix the root cause!
- (2004.03.14 - Richard)
* [Gtk1] [Gtk2] No longer clear "Select" field in the download queue
after pressing [enter].

* [Gtk1] Minor layout change on the downloads pane.
* Really remove file from disk when pressing "Purge" in the fileinfo page.
- (2004.03.10 - RAM)
* Increased size of gnet header response for better Crawler replies, since
GTKG can support 200+ leaves.
- (2004.03.09 - RAM)

* [Gtk2] Minor layout change on the nodes panel
* Regenerated glade files
- (2004.03.03 - RAM)
* Removed constraint on bg_task_signal(): can be called from a non-running
task, since otherwise daemon taks can have difficulties using it in their
start/end callbacks!
* (move.c) Added termination signal handler to allow background task to
remove the target file if GTKG is shutdown in the middle of a move
operation.
* On restart, when re-queuing a file with a computed SHA1 for moving, don't
forget to suspend all the queued files. Normally this is done when we
start the SHA1 computing process, but that can be bypassed when restarting.
- (2004.03.02 - RAM)
* As per RFE #906834, use ISO timestamps in User-Agent string.
* New version of Spanish translation by Paco Arjonilla.
* [GTK2] Updated for 64-bit Gnet stats. [Patch from Russell Francis]
- (2004.03.03 - Jeroen)
* Fixed compiler error on some compilers
* When in random port mode, retry a new port of the random chosen port
could not be binded. (Also the 1 - 1024 is now tried)
* HSEP Typo fix from Thomas
- (2004.03.02 - Jeroen)
* Included HSEP patch 5 from Thomas.
* Added shell patch 6
* Default port is now 0, which is now treated as 'choose a random port'. So
all new installations will now choose a random port to listen on.
- (2004.03.01 - RAM)
* (hsep.c) Cleanup of code, and fixed a bug on big-endian machines.
* Made header_get_feature() more robust, to avoid matching sub-words.
- (2004.02.29 - Jeroen)

- (2004.02.21 - RAM)
* Added compact_size64().
* Switched Gnet stats to 64-bit arithmetic.
- (2004.02.16 - Emile)
* [GTK1] When a parent node is downloaded from the search tab (but not its
children), GTKG will now correctly update parent hashtable
(fixes bug #892593).
* [GTK1] When search results are sorted by count, GTKG will now correctly
re-sort column if a single node is downloaded
- (2004.02.15 - RAM)
* Also use "friendly download name" (i.e. non-URN) when renaming completed
file locally after a failed copy.
* Protect against "errno == 0" on failed open().
* Even if we can't start the move/verify thread correctly for an item,
invoke the download state change callbacks.
* Must use integer arg when calling ctype functions (fixes bug #897252).
* Must count two file descriptors per upload slot and active download: one
for the socket and one for the file being read/written.
* New properties "file_descriptor_shortage" and "file_descriptor_runout".
* Activate "file_descriptor_shortage" each time we call ban_reclaim_fd()
and we succeed. We set "file_descriptor_runout" when there is nothing
more to reclaim. Both properties are reset after 10 minutes.
- (2004.02.14 - Richard)
* [Gtk1] Try to avoid memory corruption during selection in search results due
to recursive calls of on_ctree_search_results_select_row().
Should close #892802.
* [Gtk1] Added a general gtk_ctree_count_node_children() to gtk-missing.[ch].
* [Gtk1] [Gtk2] Removed property PROP_JUMP_TO_DOWNLOADS.
I don't think we need this anymore.
* [Gtk1] Added PROP_SEARCH_CASESENSE. This controls if the name column in the
search results is sorted case-sensitive.
* [Gtk1] Cleant up a few places in search_gui.c and fixed part 2 of bug #892593
in the process. Maybe part one is also fixed.
* [Gtk2] Fixed compiler warnings about redefinition of g_string_printf and
g_string_printfa in malloc.h.
* Number of leaks is now reported in the leak summary.
* [Gtk1] Small GUI layout fixed in the downloads and fileinfo panes.
- (2004.02.13 - RAM)

* Fixed a couple of compiler warnings
* Fixed a possible segfault when using ICU and iconv_open failed
- (2004.02.06 - Richard)
* [Gtk1] Fix sorting by name in the search panel. Result from
search_gui_compare_records() was interpreted wrong.
* [Gtk1] Changed search_gui_quick_sort_array_swap to be faster.
- (2004.02.01 - RAM)
* Don't include a partial file in the mesh if we don't have 512K of it, or
at least 10% of it.
* Added IP:port + vendor string to warning about weird HTTP status.
* Fixed looks_like_urn() which was not detecting names made out of a
single SHA1.
- (2004.01.31 - RAM)
* Reopening the 0.94u line.
* Allow main window to shrink width below 933 pixels (fixes bug #885659).
* When moving files, don't leave the target file around when an error occurs.
- (2004.01.27 - RAM)
* Security fix in proxy code [Found by Leonardo H. Liporati].
- (2004.01.27 - Hans)
* [Gtk2] Show progress bars in the up- and download lists to indicate
progress [from Russell Francis, patches 873182 and 874590].
# v 0.93.3 2004.01.25 [stable]
- GUI updates:
. New node info display configuration: show library size / # of files shared,
configurable from the Config / User interface pane.
. Number of file descriptors currently used for banning is now shown.
. Increased search results sorting speed for GTK1.
. Moved "close" button for searches to a more convenient position, in
the upper right corner.
- Default number of node connections raised to 12 now that many servents
support high outdegree.
- Eradication of memory leaks.
- Enhanced flow-control algorithm that will more aggressively drop packets
(including query hits) when the connection remains clogged for too long.
This new "swift" mode is indicated by the 'S' flag instead of 'F'.
- Bug fixes: #846755, #876011, #857075, #874596, #859761, #762121.
- (2004.01.25 - RAM)
* If the last QRP patch message contains only zlib trailer data to mark
the end of stream, don't consider it as a spurious message: just ignore it.
- (2004.01.20 - RAM)
* Only call message_add() at the end of forward_message() since that call
could modify the validity of the `dest' list we get as an argument.
(should fix bug #846755 and bug #876011).
- (2004.01.19 - RAM)
* Abort download_clear_stopped() if there's nothing in `sl_unqueued'.
* Don't call downloads_gui_init() before settings_gui_init().
* Fix overwriting of already read data when parsing more than one line
[Patch from Thadeu Lima de Souza Cascardo, fixes bug #857075].
- (2004.01.18 - RAM)
* Changed minimum for "node_connected_timeout" to 120 and the default to 180,
since we must account for possible flow-control, both at the node and TCP
level.
* Try to account for PARQ active upload slots when looking whether we have
enough file descriptors to become an UP, but lower the impact of banned
fd since we can now steal them when we run out of available ones.
* Lowered banned IP timeout to 6 hours, and mark IP as bad on connect timeout.
* Fixed default returned value for add_host_to_cache() to FALSE.
* (downloads_gui.c) Optimized to do without the costly count_node_children()
routine.
* Routine gui_update_download_clear() now only records that we need to
figure out the sensitivity of "Clear Stopped". However the real change is
only performed once per second via gui_update_download_clear_now().
* Must perform downloads_gui_init() before settings_gui_init() due to
the use of property callbacks that can trigger GUI code, and because we
now cache the results of lookup_widget() in downloads_gui.c.
* Periodically call gui_update_download_clear_now() from download_timer().
- (2004.01.18 - Richard)
* Count number of unstable nodes and hits on node_is_bad and node_ip_is_bad.
Numbers are reported if core debug level is > 1.
* Don't add bad ip adresses to the host caches in extract_field_pongs.
* [Gtk1] Disable "expand all" and "collapse all" when no search is open.
* [Gtk1] Fix possible crash if sorting on less then 50 results (Thanks Emile).
- (2004.01.17 - RAM)
* Allow 6 unanswered "alive pings" in a row instead of 4 for UP connections.
* Fixed incorrect list_delete_link_track() implementation causing memory havoc.
* (search_gui.c) Removed needless atom_str_get() calls.
* Redirect big walloc() calls to malloc_track() under TRACK_MALLOC,
instead of g_malloc(), to not lose the source of the leak.
* (dmesh.c) Made sure we cleanup the banned mesh by IP at close time.
* Added g_string_*() trapping when -DTRACK_MALLOC.
* Fixed stupid (recent?) typo preventing proper recording of the user-agent
for uploads.
* (downloads.c) Fixed memory leak.
- (2004.01.17 - Richard)
* Cleaned up gtk-missing.h.
* [Gtk1] Hopefully fixed sorting when any node in the results was expanded
by iterating only over the top-level nodes when sorting. Refactored
some of the code in the process and added a couple of FIXMEs for later
releases.
* [Gtk1] Hopefully fixed a few memory leaks in the download pane probably
caused by calling g_list_free() not on the first element of a GList.
* [Gtk1] In the search pane two more leaks reported by the leak detection
code should be fixed.
* [Gtk1] Fixed crash when "expand all" or "collapse all" was pressed and
no search was open.
- (2004.01.16 - RAM)
* Added trapping of g_slist_() and g_list_() routines that allocate linkable
objects under the hood. Added trapping for hash_list new/free as well.
* (bsched.c) Fixed list leak.
* (uploads.c) Fixed possible atom leak.
* (downloads.c) Forgot to cleanup d->escaped_name at exit time.
* (uploads_gui.c) Made an explict free_data() callback for TRACK_MALLOC.
* (nodes.c) Fixed memory leak.
- (2004.01.16 - Richard)
* Replaced a number of g_free with G_FREE_NULL.
* [Gtk1] [Gtk2] Moved "close" button for searches to a more convenient
position in the upper right.
* Made dmesh_remove state if it really removed something (preparetion
for XNalt support).
* [Gtk1] Integrated fast-sorting patch from Emile le Vivre.
* Moved init code from main_gui to downloads_gui.
* Moved hash_list code from glib-missing.[ch] to hashlist.[ch].
- (2004.01.15 - RAM)
* Added tracking for atoms (enabled with -DTRACK_ATOMS).
* (dmesh.c) Fixed atom leak.
* (gwcache.c) Fixed atom leak.
* (huge.c) Fixed memory leak.
- (2004.01.14 - RAM)
* Added custom debugging malloc support.
* Added trailing inclusion of "override.h" to all C files.
* (share.c) Removed spurious comment termination.
- (2004.01.13 - RAM)
* (downloads_gui.c) Removed spurious g_strdup() call.
- (2004.01.12 - RAM)
* Display the amount of file descriptors currently used for banning.
* New property "banned_count".
* Default number of node connections raised to 12 now that many servents
support high outdegree.
* Don't ping all our neighbours on pong-cache expiration: only select
20% of them, randomly, with at least 3 being selected.
* (event.c) Fixed free(0) call and switched to walloc() for subscriber
allocation.
* Must use file_fopen_missing() when reading the pid file.
* New flow-control mode called "swift" mode, shown with an 'S' instead of 'F'.
This mode is activated when we have spent some time in flow-control and
need to flush the queue faster, at the price of dropping more messages,
and possibly some query hits.
* Changed minimum for "node_tx_flowc_timeout" to 90 secs (was 60 secs)
since new "swift" mode needs at least 70 secs to clear the FC condition
with 95% probability.
- (2004.01.11 - RAM)
* Fixed "fi->lifecount > 0" assertion failure when backing out data after a
resuming mismatch.
* When we run out of socket descriptors, try to close a banned fd, if any
(both when making out a new connection or accepting one).
* Made ban_reclaim_fd() a public function, that can be used when we run out
of file descriptors.
* Make sure pixmaps and other regular files are installed without
the 'x' bit set.
* Generalized call to ban_reclaim_fd() when opening files on out-of-fd
condition by introducing the file_open() and file_create() calls.
* Decreased node unstable cleanup timer from 1 day to 0.5 day.
* New node info display configuration: show library size / # of files shared.
* New properties: "show_gnet_info_shared_size", "show_gnet_info_shared_files".
* When applying a patch message, make sure they did not already fill the
QRP table before processing (should fix bug #762121).
* Don't blindly assume pong information with hops=0 comes from the node,
as LimeWire suffers from a bug breaking this assertion.
* For prettyness, don't show a library size of 8K when the # of files shared
is 0 (all UP will advertise 8K sharing so that this amount is a power of 2).
* Remove -licuuc from the list of libs when it is present but does not
contain the functions we want (fixes bug #859761).
* Don't force bit 0 of amount of Kbytes shared to 1 if they share nothing.
* Don't consider pongs with less than 8 kbytes shared as being ultra pongs.
* Added file_open_missing(), and file_fopen*() routines.
* Error logging is now assured by file_open*() and file_fopen*() routines.
- (2004.01.10 - RAM)
* Fixed assert failure when all the entries from the cache are deleted.
* When GTKG thinks it is offline, don't even try to do GWebCache updates.
* [GTK1] Fixed titles[] array sizing using enum constants, avoiding too
small sizing causing memory corruption [Patch from Thomas Schuerger].
* [GTK2] Don't abort a download entry if it is a pseudo-header [Patch
from Russell Francis] (fixes #874596).
- (2004.01.10 - Richard)
* [Gtk1] [Gtk2] Reverted changes to hostcount display from 2004.01.08
* Moved generation of hostname for downloads pane to downloads_gui_common.c.
* Fixed a memory leak in search_gui_common.c when search_hide_downloaded
was activated.
- (2004.01.08 - Richard)
* [Gtk1] [Gtk2] Show active and trying hosts seperatly when counting hosts
in download pane. Format: "n hosts (m)" n - active, m - trying.
# v 0.93.2 2004.01.05 [stable]
- (2004.01.05 - RAM)
* Fixed memory leak.
# v 0.93.2 2004.01.04 [stable]
- Numerous GUI updates:
. GTK1 now supports groupped searches and groupped downloads, like GTK2 did.
. GTK1 and GTK2 GUIs were brought in sync feature-wise, as much as possible.
. Gnet pane will now show leaf nodes and normal nodes in light gray.
. Fixed memory leak problems in the GTK2 interface that slipped in 0.93.1.
- Bandwidth requirements to become an ultranode were lowered significantly.
This is due to the filtering of SHA1 queries through QRP now, instead of
systematically forwarding them: gtk-gnutella assumes all servents out there
include the SHA1 URNs in their QRP tables.
- As a result of the above, default amount of leaf nodes was increased.
- Added a special fix for BearShare: the HTTP headers which gtk-gnutella
emitted used continuations, and were well-formed, but BearShare was
misparsing those, causing it to enter an endless loop...
- Search results are now buffered by the GUI for burst updates, which reduces
CPU usage and the amount of redrawing significantly. The buffering time
is configurable from the GUI.
- gtk-gnutella is now fully compliant with LimeWire regarding I18N queries,
provided you have the ICU library. Otherwise, it should be OK for roman
charsets only.
- (2004.01.04 - RAM)
* New property "search_accumulation_period" for burst period configuration.
* Made the burst interval period for search refresh configurable from the GUI.
* New header formatting routines: header_fmt_set_line_length(),
header_fmt_value_fits() and header_fmt_append_value().
Changed signature of header_fmt_make() to include default separator.
Default line length set to 78 chars (was 72).
* Changed signature of dmesh_alternate_location() to include whether we're
emitting alt-locs in a request or in a reply.
No longer format X-Alt and X-Nalt with continuations in requests, and
to BearShare nodes on replies (due to a parsing bug in BS causing its crash).
* Lowered min size for QRP tables to 16K.
* Finished normalization of filenames/queries when the ICU library is
present [From Stephane Corbe].
- (2004.01.04 - Hans)
* [Gtk1] Show leafs and "normal" (legacy) clients in grey in the nodes list.
* [Gtk2] Update nodes and uploads lists to show rows in grey in line with Gtk1
* Updated i18n .po and .pot files based on current code
* Updated Dutch translation
- (2004.01.04 - Richard)
* [Gtk1] [Gtk2] Show icon when gtkg determines that it is ancient.
* Props that have default values are saved as comments, so they can be
upgraded to new defaults on version upgrades. [from Globuz]
* Fixed critical bug in results-bursting code.
- (2004.01.04 - Emile)
* [Gtk1] Fixed autosort for "count" column
* [Gtk1] Added "Push mode" status for downloads tree
- (2004.01.04 - Richard)
* Implemented "results bursting". That means that the gui accumulates
incoming results over a period of time and then flushes them out to display
in a burst.
This technique drastically reduces the number of redraws. Unfortunately I
had to inject some #ifdef USE_GTK1 into search_gui_common.c. I hope you can
bear with me ;) The burst interval is currently hardcoded at 5 seconds
in search_gui_common.c::search_gui_flush().
* [Gtk1] "results burting" causes CTrees affected by the burst to be frozen
during the burst and unfrozen later.
* [Gtk2] the TreeViews are not frozen, but Gtk2 seems to handle the burst
intelligently and doesn't redraw during the burst all by itself. *shrug*
Further testing is required here.
- (2004.01.03 - RAM)
* Added a continuation on X-Queued: line, which was longer than 80 chars
when we emit lifetime and ETA information.
* Now count failed push proxy resolutions as well.
* Now always emit alternate locations via X-Alt:, so got rid of the old
code that emitted X-Gnutella-Alternate-Location headers.
* Lowered maximum query monitoring half life to 10 seconds.
* Changed computation formula for QRP pass-throw now that we filter SHA1
queries through the table. The cut-off is now fixed at 5%.
* Another series of patches from Emile le Vivre:
[GTK2] emove expand/collapse all buttons from search pane because they
didn't fit and because the expand all button wasn't updating the
treeview.
[GTK1] Fixes autosort (except for count column for some reason)
[GTK1] Adds "connecting" and "queued" status messages to grouped downloads
[GTK1] Fixed "restart search" seg fault
[GTK1] Fixed autoselect to update the ctree so autoselected rows show up
immediately.
* (downloads_gui*.c) Removed spurious atom_int_get()/atom_int_free() calls
that do not strike me as beeing needed, but added explicit atom_int_get()
in the add_parent_with_fi_handle() routine.
* (downloads_gui.c) Made sure the hash tables are declared with g_int_hash
and g_int_equal to work properly with integer keys.
* (downloads_gui.c) Avoid too frequent updates and structure traversals to
update the parent tree summary info when its GUI info is fresh enough.
* Fixed long-standing race condition when receiving a GIV string.
* [GTK2] Fixed crash when clicking twice on Purge in the fileinfo pane [From
Hans de Graaff].
* Changed default for "node_rx_flowc_ratio" to 70%, and raised minimum
to 30%, to allow traffic bursts.
- (2004.01.03 - Richard)
* [Gtk1] [Gtk2] Lots of layout changes to assimilate the gtk1 and gtk2 guis,
to clean up layout in general and to fix paddings and spacings.
* [Gtk1] [Gtk2] Unhid the "current search" entry in the search panel again
as users requested so.
* [Gtk2] Applied patch to fix column visibility on the gnet pane
[from Clayton Rollins].
- (2004.01.02 - RAM)
* Fixed conflict ratio computation when they don't share anything.
* New properties to control ancient versions.
* Warn them before the version becomes too old, and refuse to run without
user manual action when we become old, after some grace period.
* A series of patches from Emile le Vivre:
[GTK1] Adds grouped downloads
[GTK1] Adds collapse/expand buttons to downloads tab
[GTK1] Fixes errors in autoselect
[GTK1] Fixes memory leak
* Offer ability to backout file by some amount on resuming mismatch
[From Hans de Graaff].
* Changed definition of char_map_t to be guint8 instead of (signed) char.
* Count and display in gnet stats pane the amount proxified push messages
we relayed or broadcasted.
* Fixed hole in flow-control updating after message write.
- (2004.01.01 - RAM)
* Halved requirements for gnet connections: with dynamic querying, there is
less traffic between peers (GTKG does not support it yet though).
* Raised size of gnutella handshake reply and that of generated crawler
info to accomodate the larger number of leaves we can now support.
* [GTK1] Added treeview in search results, in line with GTK2's GUI [From
Emile le Vivre].
* Don't remove gtk-gnutella.pot in "realclean" since we distribute it.
* When looking at memory requirements for becoming an ultranode, take into
account flow-control via the maximum message queue size.
* Fixed assertion failures, and cleaned-up style issues, unused variables.
* Update gnet connection counts in gnet bandwidth progressbar immediately
when user changes some maximum, in ultra mode.
* Factorized drop message logging in gnet_stats.c.
* A series of patches from Emile le Vivre:
[GTK2] Adds "expand/collapse all" popups for search and download tabs
[GTK2] Adds "expand/collapse all" buttons for search tab
[GTK2] Adds "Search results" frame around searches tab (missing since
we moved the new search entry to the lefthand pane).
* Applied ICU patch from Stephane Corbe.
- (2003.12.31 - RAM)
* Added "emergency fixing" code: if the downloading partition gets trashed,
one can now reconstruct a fileinfo with "grep -v ^CHNK fileinfo", and
gtk-gnutella will correctly reset the entries on startup (all empty, but
kept; otherwise gtk-gnutella would delete entries for missing files).
* Moved periodic refreshing of fi->recv_last_rate into the core, where
it belongs.
* Wrote qrt_eq() to check whether the new table we've built is identical
to the previous one: don't install if no change.
* If the incremental routing patch is larger than the default one against an
empty table, discard it in favor of a RESET plus the default patch.
* Filter SHA1 queries differently: don't forward them blindly if there's no
matching in the QRP table, and don't forward them to leaves in TX flow
control.
* [GTK2] Fix time remaining and k/s status for grouped downloads: now
uses the core-computed fi->recv_last_rate value [From Emile le Vivre].
* A series of patches from Emile le Vivre:
[GTK2] Fixes the memory leaks introduce by Emile's grouped downloads patch.
[GTK2] Fixes quirky behaviour for abort popups.
[GTK2] Aborted grouped downloads now update status column correctly.
* Apply socket RX buffer changes for downloads and nodes immediately to all
existing connections.
* Now advertises Query-Routing 0.2.
* Now that we no longer forward all SHA1 queries to leaves, the bandwidth
requirement per leaf has dropped significantly. Increased the default
number of leaves and halved b/w requirement to 32 bytes/sec/leaf.
* Update flow-control indication within make_room() in case we dropped
enough messages to go below the low watermark.
- (2003.12.29 - RAM)
* Removed logical negation causing extra ultranode connections to be rejected
with "Reserved slot" instead of the appropriate "Too many ultra nodes".
* [GTK2] Fixed column selection in gnet pane: it's a tree in GTK2, not
a clist [From Clayton Rollins].
# v 0.93.1 2003.12.28 [stable -- 2nd version]
- (2003.12.29 - RAM)
* Restored "hu" support -- did not see the hu.po there.
* Added po/hu.po and src/downloads_cb2.h to MANIFESTs.
# v 0.93.1 2003.12.28 [stable]
- Simplified the GUI for non-experts. Beginners will now see less
curious things on the screen, until they become more acquainted and
turn on "expert" mode.
- Many improvements in the GUI:
. The Gnutella node information displayed can now be configured in
detail, and is by default reduced to four statistics only.
. It is possible to hide the handshaking version and the Uptime column
from the Gnutella pane.
. When running in auto mode, show the criteria for becoming an ultranode.
. The leaf node bandwidth odometers are by default automatically hidden
when running as a leaf node.
. GUI refreshing has been optimized so we don't unnecessarily refresh
screens that the user is not looking at. The downside is that when
moving to that screen, stale data is presented for about 1 second until
the refreshing takes place.
- 0.93 was not reporting uploaded partial files as such to downloading peers.
- Remote control "shell" is now compiled in by default but needs to be
explicitly enabled in the GUI to become operational.
- Improved connectivity between ultrapeers to avoid frequent disconnection
due to "activity timeout".
- Bugfixes:
. Was misparsing query hits bearing alt-locs attached to each hit, causing
GTKG to possibly drop those hits and close the connection when coming
from an immediate neighbour.
. When restarting a search from menu, re-enable it automatically if it
was disabled (fixes bug #864348).
. Upon restart, a disabled search will now be shown in gray in the
search list (fixes bug #857972) -- feature only implemented for GTK1.
- Many other little changes that we'll let you discover...
- (2003.12.28 - RAM)
* [GTK1] Renamed "Search for" as "Search:" to save horizontal real-estate
and have a larger search box.
* Ensure that we update the uploads every 5 minutes at least, even if nobody
is watching to perform cleanup of dead entries.
* [GTK2] Brought up in sync with GTK1 [From Clayton Rollins].
* Ensure that we update the nodes every 5 minutes at least, even if nobody
is watching to perform cleanup of dead entries.
* Cache result of lookup_widget(main_window, "notebook_main").
* Put column definition enum for gnet pane in gui.h, to be in line with
the way it's done for others.
* Only update downloads if we're in the "Downloads" tab.
* Put column definition enum for fileinfo pane in gui.h, to be in line with
the way it's done for others.

* [GTK1] Added "expert" statistics frame showing library scanning time and
some properties about the QRP table and the generated patch in the upload
config pane.
* New "fileinfo_divider_pos" property to remember the postion of the
fileinfo vertical separation.
* [GTK1] Remember the vertical position of the fileinfo pane separation.
* Fileinfo callback were not prepared to handle (FREQ_SECS, 2), otherwise
change notifications are lost when adding/removing sources.
* Forgot to handle the GTA_DL_REQ_SENDING state in download_timer().
Now that we do, we can skip the GUI update for that state if they're
not looking.
* [GTK1] Turned off "expand" from "frame_gnet_can_become_ultra".
* [GTK2] GUI brought up in sync with GTK1 again [Thanks to Clayton Rollins].
- (2003.12.27 - RAM)
* Due to a stupid typo, we were denying promoting nodes to UP even if the
bandwidth requirements were met [Patch from Sebastian Bork].
* [GTK1] Upon restart, a disabled search will now be shown in gray in the
search list (fixes bug #857972).
* When restarting a search from menu, re-enable it automatically if it
was disabled (fixes bug #864348).
* Added properties to track ultrapeer eligibility status and switching time.
* [GTK1] Added a frame showing ultrapeer promotion statistics when running
in "auto" mode.
* Applied cleanup patch for tree-view downloads (GTK2) [From Emile le Vivre].
* Added new properties for configuring the search queue, whether to enable
the "shell" remote control, whether and how tightly we should monitor
query traffic for duplicates, and for how long we should keep "dead"
entries for GUI display before removing them.
* Fixed download columns for GTK1, broken by Emile's patches.
* Raised atexit() timeout to 20 seconds.
* When computing average servent uptime and IP lifetime for ultranode
promotion, take into account the current uptime and IP lifetime.
* Query traffic monitoring is now controlled by GUI-settable properties.
* Must always perform nodes_gui_node_info_changed().
* Must always perform upload_info_changed().
* When autoselect is disabled in the search pane, prevent them from being
able to select the fuzzy matching or identical settings...
* Now that remote control can be disabled from the GUI, compile it by
default but do not activate it.
- (2003.12.26 - RAM)
* Don't send QUEUE callbacks for entries we no longer share [Patch from
Hans de Graaff].
* Changed min/max values for Gnutella message sizes now that they can be
configured from the GUI.
* Introduced many new GUI properties:
. node_show_uptime
. node_show_handshake_version
. node_show_detailed_info
. show_gnet_info_XXX [15 of them]
* [GTK1] Added ability to configure Gnutella message sizes in expert mode,
as well as the ability to customize some of the columns and info display
in the gnutellaNet pane.
* Use dynamic configuration to generate the node "Info" column display.
* Added symbolic constants to refer to node columns.
* Optimize GUI refreshing of nodes and uploads to only perform it when
the GUI displays the node or upload page.
* Integrated bugfix in random chunk shuffling for PFSP [From Hans de Graaff].
* Applied patch to introduce tree-view for downloads [From Emile le Vivre].
- (2003.12.25 - Richard)
* Increased similarity between gtk1 and gtk2 interfaces.
* [Gtk1] [Gtk2] More padding fixes.
* [Gtk1] In bandwidth config panel changed layout to match that of the
Gtk2 interface.
* [Gtk1] [Gtk2] Updated gui maintainer entry in about dialog.
* [Gtk1] [Gtk2] Changed label of expert mode toggle to
"Show additional information and settings for advanced and expert users"
* [Gtk2] Added "Compute upload connection speed" setting to config pane.
* [Gtk2] Socket recieve buffer size settings visible only in expert mode.
* [Gtk2] No more Gtk-Critical when loading gtkrc file. rc-file loading code
now uses ~/gtkrc for gtk1 and ~/.gtkrc-2.0 for gtkg. This is correct
on my Debian system and hopefully also on other systems. (Analogous for
the rc files in the gtkg config dir.)
- (2003.12.24 - RAM)
* Transferred bytes are now shown in short size form, followed by the
verbatim value between parenthesis.
* Added a short_size64() routine for 64-bit values.
* Don't call bsched_clear_active() too often: only once per period.
* PARQ will now guard a slot for 45 seconds after a remote disconnect.
* Special handling for stalled uploads being replaced in parq_upload_get().
* Enforce the maximum uploads per IP after PARQ, since it seems there is
a race condition somewhere.
* [GTK2] Fix from Russell Francis putting back socket RX buffer size
selection into an "expert" frame.
* Treat all input exceptions during download as an EOF condition.
- (2003.12.24 - Richard)
* [Gtk2] Changed lots of paddings and spacings so they are more uniform.
* [Gtk1] [Gtk2] Applied suggestions of Emile le Vivre for gui simplification:
- moved to expert mode:
- hostcatcher (gnet panel)
- transfered files stats (gnet panel)
- local node information (gnet panel)
- 'add passive' searches (sidebar)
- Searches: current search combo removed (only hidden for now),
redesigned settings panel, moved adding of new searches to sidebar,
moved a few buttons around
- Sidebar: moved adding of new searches here
- Config: a few minor changes in the gnet settings to make gtk1 and gtk2
look more similar.
* [Gtk1] [Gtk2] Added option to automatically hide leaf bandwidth stats
when not in ultrapeer mode (default: on).
* [Gtk1] Fix sidebar resizing when traffic stats are hidden (a hack, but
it seems to work)
- (2003.12.21 - RAM)
* Don't update drop statistics on high TTL when running as a leaf node and
don't bother running through the routing computation for forwarding
a message since leaf nodes will never actually route messages.
* Don't queue up a new query message in the queue if we already have an
unsent message in the queue originating from the same search.
- (2003.12.20 - RAM)
* PARQ will no longer send QUEUE when uploads are disabled.
* Changed semantics of reported connection speed: it is now the connection
speed in kbits/s for each upload slot, not a global one.
* New property "compute_connection_speed", TRUE by default.
* [GTK1] Added GUI interface for "compute_connection_speed" configuration.
* [GTK2] Patch from Russell Francis adding the avail b/w display like in GTK1.
- (2003.12.17 - RAM)
* Changed some property defaults:
node_monitor_unstable_servents -> FALSE (was TRUE)
max_leaves -> 48 (was 100)
* Changed minimum bandwidth requirements per leaf (128 bytes -> 64).
* [GTK1] Removed unused "Default minimum speed" configuration in the
Config / Gnutella pane.
* [GTK1] Changed increments for bandwidth changes via PageUp and PageDown
to be 5 units, and increments for the speed reported to peers to be 8 units.
- (2003.12.16 - RAM)
* New property "dl_http_latency".
* Downloads now maintain a measure of the HTTP latency between request
and reply.
* [GTK1] Added display of total limited bandwidth in the Config / Bandwidth
pane, as well as the current measure of the HTTP latency.
* Don't count TTL=0 messages when we're a leaf node since we handle them.
- (2003.12.15 - RAM)
* Changed some timeouts minima values, and added the ".aac" extension (MP3
clone from Apple).
* Added two new properties: "download_rx_size" and "node_rx_size" to
configure the socket RX buffer size.
* [GTK1] Added "expert" settings to configure the RX buffers of sockets.
This can greatly impact the latency when downloading many files or
connected as an ultranode.
- (2003.12.14 - RAM)
* Removed remaining Gnutella 0.4 handshaking code.
* Fixed IP TOS settings: only change it when downloading/uploading, but
leave normal TOS when exchanging headers.
* Don't forward random pongs to leaves that are already in TX flow control.
- (2003.12.13 - Jeroen)
* Intergrated patch from Clayton, adds vendor preferencing to the gui
- (2003.12.11 - RAM)
* Changed compact_size() to display an even more compact string when the
size is an even multiple of Kbytes, Mbytes, etc...
* Added some query routing table stats for ultrapeers to monitor their leaves.
* Suppressed activity timeout between ultra nodes and leaves.
- (2003.12.10 - RAM)
* Added warning when running under debug level tracing the BYE received.
* When we're a leaf node, don't issue any "Activity Timeout" to our
Ultranodes. If the connection went dead, this will be caught by their
not replying to our alive pings, after 8 minutes.
* Added query throttle.
* Make sure to initialize `last_update' when creating a node, to avoid
it being immediately selected by the node_timer() thread for removal!
Restored the activity timeout check...
* When remote Gnutella node does not reply correctly or issues a 401 reply,
remember his IP address as being bad.
* Keep query/ hit statistics per node (TX & RX) and measure QRP efficiency
for leaf nodes.
- (2003.12.09 - Jeroen)
* Intergrated and somewhat adjusted patch from Thadeu Lima de Souza Cascardo.
Use the WHATIS command in the remote shell to get the 'tooltip' of a
property
* Intergrated and modified patch from 'wwp' to parse gtkrc file in local
directory and gtk-gnutella config directory
* Intergrated and somewhat adjusted patch from Paco Arjonilla.
Added internationalization for the gnutellaNetstats tab messages.
* Changed the following default settings:
- max_connections 4 -> 9
- node_connecting_timeout 10 -> 30 seconds
- node_connected_timeout 45 -> 90 seconds
- node_tx_flowc_timeout 60 -> 180 seconds
- scan_extensions added: xvid
- strict_sha1_matching FALSE -> TRUE
- prefer_compressed_gnet FALSE -> TRUE
- download_require_server_name FALSE -> TRUE
- max_leaves 15 -> 100
- node_monitor_unstable_servents FALSE -> TRUE
- unique_nodes 67 -> 50
- (2003.12.09 - RAM)
* Allow them to issue a duplicate upload if the original began to stall.
The new upload will simply replace the previous one.
* Added "[weird #n]" tagging string to all debugging warnings emitted when
we increase the weird message count for a node.
* Was misparsing HUGE URNs followed by GGEP extensions, causing spurious
"Security Violations" disconnections from GTKG peers.
* Throttle queries that are re-emitted too soon or too closely in time
to not be related.
* Renamed "Ping throttle" as "Message throttle" since we can now throttle
both pings and queries.
- (2003.12.07 - RAM)
* Count the amount of bytes actually sent back for each upload request.
This amount is displayed when a data timeout occurs.
- (2003.12.04 - RAM)
* Don't attempt QUEUE callback if we don't have enough bandwidth left to
issue a connection.
* Exported socket_tos_*() routines and added sock_is_corked().
* Detect recurrent upload stalling conditions, and try to workaround
the problem.
- (2003.12.03 - RAM)
* Try to account for the bandwidth used by TCP/IP, which can become
significant when many connections are issued concurrently.
* Don't return alt-locs for ourselves if they enabled PFSP-server but
disabled sharing for now.
- (2003.12.02 - RAM)
* Now shows real instantaneous bandwidth usage and not a fast EMA.
* Fixed some possible usage of uninitialized variables.
- (2003.11.25 - Jeroen)
* Removed dead gnucleus gwebcache
- (2003.11.24 - RAM)
* Don't hammer the same webcache if we can't connect.
* New strcmp_delimit() routine to compare strings up to a delimitor.
* Revisited node_avoid_monopoly() and node_reserve_slot().
* [GTK1] Was not low-lighting the right search in list when disabling.
* Added check for EACCES for FreeBSD.
- (2003.11.22 - Jeroen)
* You can now reserve a number of slots for gtk-gnutella nodes only
(current default: 33%)
* You can now prevent one vendor from taking over all your gnutella
node slots. Current efault one vendor may take maximum of 67%.
These settings are not available through the GUI
- (2003.11.11 - RAM)
* Fixed http_send_status() to no longer ignore the given keep_alive parameter,
even with 2xx return codes.
* Pass the u->keep_alive status to http_send_status() on 2xx replies.
- (2003.11.10 - RAM)
* Use average upload bandwidth consumption to compute PARQ ETA values.
* Flag query hits carrying a push-proxy indication.
- (2003.11.09 - RAM)
* Forgot to include "settings_gui.h" in main.c.
* Forgot to allow X-Available-Ranges emission on HTTP 2xx returns.
* Don't expire pong cache for leaves as often as in ultra mode.
- (2003.11.08 - Jeroen)

* Fixed assertion bug for GTK2.
- Both GTK1 and GTK2 should be fully functional / usable again
- (2003.11.03 - Jeroen)
* Fixed a lot of compilation warnings, also fixed some errors which actually
could cause a segfault when running in a high debug level
* Was not always sending the X-Features were it actually should, fixed.
# v 0.93 2003.11.02 [stable]
- GTK-Gnutella now support both Partial File serving, as a client as well
as a server. As soon as a download is started, can be used as an alternate
source for others even though the download is not completed yet.
- When a mismatch happens during downloading the file can now be automatically
removed and restarted again.
- Improved GUI to specify better which downloads should be cleared from the
list (completed, failed, unavailable)
- Collects alternate download locations aquired from query hits.
- Support for hostname instead of only an ip. If you have a dynamic ip
but got a static hostname, for example a .dyndns.org address, gtk-gnutella
can try to connect to the ip associated with the hostname.
- Sends out alternate locations which should not be tried.
- Won't send full headers when short on bandwith.
- Any changes in settings are now automatically saved, there is no need to quit
the client anymore to make sure the settings are saved.
- Running gtk-gnutella in Auto peermode should no longer cause a crash.
- New addresses in hostiles.txt to protected against malicious hosts.
- gwcache.boot was cleaned up. Dead links were removed.
- Remote control should actually work without crashing gtk-gnutella.
- The build problems which occured in 0.92.1 due to the switch to metaconfig
should be (mostly) gone.
- Code cleanup to build on more platforms.
- GTK2 interface currently does not have a maintainer, not all options which
are available in the GTK1 interface might have made it in the GTK2 interface.
- (2003.11.02 - RAM)
* Added the concept of "established" Gnutella connection: don't relay
Gnutella traffic to non-established connections. A connection becomes
established when we receive traffic or got the 3rd handshake.
* Don't forget a cache URL when it reports an ERROR: can be a transient
problem.
* Don't mark node as bad when an EOF condition occurs but the Gnutella
connection is not "established". It could be the result of a timeout
on the other end, and without an established connection, no BYE is
possible.
- (2003.11.01 - RAM)
* Account for BearShare 4.3.x no longer sending the X-Ultrapeer to signal
Ultrapeer status but relies on X-Ultrapeer-Needed instead.
* Cleanly deny the connection to Ultrapeers requesting us to become a leaf
when we cannot be demoted.
* Do not send "alive" pings if we've been receiving data from the remote
node recently.
* Take into account the last ping round-trip time for spacing out our pings.
* Fixed getting of GUI colors in search: is done differently for GTK1/GTK2.
* Remove bad URLs from the Gnutella web cache as soon as we encounter them.
- (2003.11.01 - Jeroen)
* Now sends the X-Nalt header with sources that should not be tried.
GTKG won't parse and use it though.
* Intergrated patch from Clayton. Which adds PFS configuration options
in GTK2 too.
* X-Features now sends all features, won't skip the last feature anymore
- (2003.10.31 - RAM)
* Disable non-passive searches that became full (max configured amount
of result displayed).
* Let the GUI side tell the core side how much items were found and are
still listed in the search window.
* Added a bunch of new addresses to hostiles.txt, collected from a
.htaccess and converted to our format.
- (2003.10.31 - Jeroen)
* Added support for X-Features header parsing.
* Added support for X-Features generation.
* PARQ now also accepts the X-Features: Queue/1.0 as a queue enabled indicator
* PARQ now also emits queuing capabilities in the X-Features header.
* Don't add the X-Features header when the header would be empty
- (2003.10.29 - RAM)
* No longer emit the X-Try header during Gnutella handshaking unless we're
runnning in normal (legacy) mode.
* Changed the way the `fi_by_namesize' hash is handled: we non longer keep
one alias per (name, size) tuple but a list of them. This avoids dropping
alternate names between different fileinfo for the "same" file (albeit
bearing disctint SHA1). Non-SHA1 matching of query hits will now autoselect
an entry for downloading only if there is one known entry by (name, size).
* When a download is done, try to rename it using one of the non URN-like
aliases we have for it.
- (2003.10.29 - Jeroen)
* Fixed some inconsistent code. This should make the code even more
portable
- (2003.10.28 - RAM)
* When checking for an up-to-date SHA1 in a partial file, don't bother
verifying whether the file is still present on the disk.
* Got rid of obsolete file_info_filesize() routine.
* Added file_info_has_trailer() to check whether a file has a trailer,
indicating it is being downloaded but still incomplete.
* Don't share partial files, even if the "tmp" directory is shared.
- (2003.10.27 - RAM)
* Handle '_' as a space in looks_like_urn().
* The download pane will now try to show a non-URN alias for filename.
* Must reparent all downloads to common server when there is an IP conflict
due to DNS resolution of the server name.
- (2003.10.26 - RAM)
* Fixed async DNS resolution to behave properly when pipe with ADNS fills up.
* When creating downloads, one can optionally supply a hostname as well.
* New servent code "FEVR" for FileFever.
* Added support for symbolic hostname in downloads.
* Added parsing support for new GGEP "HNAME" extension.
* Generate the GGEP "HNAME" extension in our query hits, if possible.
* New properties "server_hostname" and "give_server_hostname" controlling
the setup and the advertising of the server's hostname.
* Added generation of the X-Hostname header.
* Added parsing of the HNAME extension in query hits.
* Added socket_bad_hostname().
* Return the X-Hostname to uploaders if possible.
* Display hostname when known for downloads.
* [GTK1] Added configuration of the server's hostname.
* [GTK1] Display hostname when known in searches.
- (2003.10.25 - Jeroen)
* Don't allow removing a download for which a background task is active. EG,
while verifying an SHA1 hash.
* Remove file on mismatch option is now also available for GTK2
- (2003.10.21 - Jeroen)
* Intergrated patch from Thadeu Lima de Souza Cascardo. This fixes a segfault
with remote control.
* Leaf, normal, ultra node counters are now updated as soon as the connection
was established. This should avoid an assert when changing modes while still
in handshake.
- (2003.10.19 - RAM)
* Rotate sources in bandwidth scheduler at each timeslice, since apparently
the order used to insert them as I/O callbacks determines the order with
which glib calls us back when they trigger.
- (2003.10.18 - RAM)
* [GTK1] Added GUI configuration for server-side PFSP.
* Trace amount of bytes in HTTP requests and replies.
* Improved limitation of HTTP replies: now based on the error code with
explicit sizing of the header and with flag propagation to callbacks, to
tell them more about the context of the reply they're generating.
* Refactored the gtk_gnutealla_exit() destruction order to avoid assertion
failures in GUI code.
* Moved some PARQ constants to parq.h.
* More carefully control the generation of the PARQ headers depending on
the callback flags.
* Keep information about the mesh information being sent to uploaders for
a longer period, to better accomodate with PARQ's long retry timeouts.
* Added more stringent size control on the generated headers in replies.
- (2003.10.13 - RAM)
* Fixed file_info_available_ranges() to avoid assertion failure at the end.
* Detect and ignore exact duplicate entries in the hostiles.txt file.
* Because of PFSP-server, we can get our own alt-locs back: make sure we
don't try to download a partial file from oursevelves!
* Added ip2_to_gchar() in case we want to format two IPs in the same printf.
* Bearshare changed its vendor tag to "BARE" in query hits.
* Re-organized gtk_gnutella_exit() to perform only minimal activities
when being called from atexit().
- (2003.10.12 - RAM)
* Added file_info_readable_filename() to get a meaningful name for uploads
related to partial files, and not an URN if possible.
* Now remember explicitly when list_clone_shift() was called and cloned,
to avoid problems with the list changing underneath.
* Removed assertions when re-reading fileinfo trailer: they could be harmful
when the trailer is inconsistent / corrupted.
* In the upload pane, prefix the Range column with a '*' when dealing with
a partial file.
* Remember the time when we rewrite the properties to disk, to avoid spurious
warning about the file having changed whilst we were running.
* Fixed `running_uploads' counting when waiting for follow-up request after
an "unavailable range" error: decrement it before waiting, since we don't
even know whether there will be a follow-up at all!
* When unlinking or resetting a fileinfo, kill all uploads targeted to it.
* When outgoing bandwidth is saturated, limit the size of the HTTP replies
we make, or the size of our HTTP requests. This includes emitting shorter
version strings, less alternate locations, etc...
- (2003.10.12 - Jeroen)
* Intergrated patch from Richard Hyde which implements the Purge button for
the gtk2 interface.
- (2003.10.11 - RAM)
[This batch of changes implements server-side PFSP]
* Add ourselves to the sent alternate locations when server-side PFSP is on
and we have some data for a partially downloaded file.
* Tell the mesh to include ourselves in the alternate locations when
downloading a file for which we have data (PFSP).
* Adapted the "shared file" structure and the lookup routines to handle
partially downloaded files: a fileinfo can now contain a "shared file" and
the "shared file" is marked as being partial by referencing its associated
fileinfo.
* New upload state GTA_UL_PFSP_WAITING entered when they request an
unavailable range and we give them one more chance to get a correct chunk
by retrying on the kept-alive connection.
* Emit header continuations with leading "\t" instead of 4 spaces.
* Raised HTTP reply size to 2.5K to give room to available ranges.
* Don't ignore files for which shared_file_by_sha1() returns something but
which are actually partial files.
* Remember in each upload whether the previous request was for an unavailable
range.
* Return a 416 to uploaders requesting an unavailable range, keeping the
connection alive to give them a chance to re-request the proper range
immediately without loosing the connection.
- (2003.10.06 - RAM)
* The property system now remembers when a saved property is changed, and
supports a new prop_save_to_file_if_dirty() call that will perform a
save only if a saved property changed since last flush to disk.
* Added lazy property saving to the slow main timer.
* Added atexit() hook to allow GTKG to cleanup properly when a library
calls exit() directly, especially when the connection with X is lost.
* Now uses GGEP "ALT" to provide known alternate locations in query hits.
* Terminate connection when peermode changed during handshaking, using
a BYE message with code 504. This race condition is rare enough to not
warrant recovery (fixes bug #799675).
- (2003.10.05 - RAM)
* Added parsing of new compact X-Alt header and generation of that new header
to servents who have shown support for it.
* Added collecting of alternate locations on HTTP 416 replies.
* Fixed update of the dl_byte_count/ul_byte_count properties (now a guint64).
* Now passes vendor string to alt-loc collection routine so that we can
record who supports X-Alt and who doesn't.
* Suppressed range header parsing warnings when not debugging.
* Now look at X-Alt when collecting alternate locations and record vendors
known to support that new compact form.
* Skip leading whitespaces when parsing IP address.
* Don't hardwire 6346 as default port, use the new GTA_PORT definition.
* Added version_newer() to check for GTKG versions being newer than a date.
* Assume all GTKG versions newer than 05/10/2003 support X-Alt even if we
have never seen an X-Alt from them.
- (2003.10.05 - Jeroen)
* Closed bug [ 790622 ] change "fuzzy filter" tooltip contents. The tooltip
was: "... Thepurpose of this filtering..." which should be ".... The
purpose of this filtering..."
- (2003.10.04 - Jeroen)
* Closed bug #784574 Transferred files byte counter rollover. Transfer counter
is now a 64 bit counter.
* Added GUIN64 to the props.tpl and corresponding files.
- (2003.10.03 - Jeroen)
* Don't assert when u->name == NULL. EG, when a file is not found
- (2003.10.02 - Jeroen)
* Added extra assertions to parq to verify u->name != NULL. Trying to track
a porting problem
- (2003.09.11 - RAM)
* My farewell to gtk-gnutella... Appointed Jeroen as new leader.
* No longer aborts downloads when we can't write data to disk: requeue them
with the "busy" retry delay.
* Fixed definition of QUERY_SPEED flags to match LimeWire's interpretation.
When they talk about bit #15, it's the bit on the wire, but since the
field is little-endiant, that's really bit #7 in the definition.
* New "dl_remove_file_on_mismatch" property to request file removal when
there is a resuming mismatch for a download.
* [GTK1] Added a "remove file on mismatch" checkbutton in download pane.
- (2003.08.26 - RAM)
* Optimized file_info_update() to not call file_info_merge_adjacent()
systematically. It now also behaves more efficiently for the common
case where we append new data to an already "done" chunk.
- (2003.08.20 - RAM)
* Had forgotten to fix IP endianess issues in filter_gui.c.
- (2003.08.19 - RAM)
* Escape leading '.' in filenames as '_' to avoid downloading "hidden" files.
* Flag aborted downloads with server unavailable as "Aborted (Server down)".
* When removing downloads from a peer that is unavailable, flag all those
downloads as unavailable as well.
* Fixed endless "Request" -> "Sinking" -> "Request" cycle.
* Changed jmake so that all install directories are made if they don't exist.
* Regenerated Configure with newer units.
* Fixed wrong Configure flags in gtk-gnutella_spec.SH.
* Configure will now ignore your xgettext if it does not support --from-code.
- (2003.08.16 - Jeroen)
* PARQ: Update all IP / Port info for all PARQ entries for this servent
when a servent sends his new IP / Port.
- (2003.08.16 - RAM)
* Updated metaconfig so that the generated config.h can compile properly
with the broken gcc 3.x pre-processor.
* Added size of arrays in external declations from gnet_stats_gui_common.h.
* [GTK1] Added new download auto-clear option: unavailable downloads only.
* New property "autoclear_unavailable_downloads" to clear unavailble
downloads only. TRUE by default.
* Renamed "Clear completed" button as "Clear stopped".
* All downloads that timeout or for which the push route is lost are
stopped via download_unavailable().
- (2003.08.15 - RAM)
* Moved the manual page from debian/ to src/.
* [GTK1] Added display of the amount of fileinfo entries, and which have
sources in the Fileinfo pane.
* New properties "fi_all_count" and "fi_with_source_count".
* Count all fileinfo, and those with sources.
* Factorized "Malformed SHA1 query" and "Query hit had bad SHA1" statistics
into "Malformed SHA1 message", since we keep track of message types.
* Renamed "Malformed UFT-8 query" into "Message with malformed UTF-8".
# v 0.92.1 2003.08.20 [stable]
These are some of the changes made since 0.92 stable:
* Support for push proxies was added which reduces problems with
firewalled servents.
* Support for pre-0.90 configuration files has been dropped.
* Improved PARQ and fixed some problems with it.
* The default directories for downloads are now set to $HOME.
* A lot of minor bugfixes and code clean-ups so that it compiles on
even more platforms and with other (C99) compilers.
* GTKG can now monitor unstable IP addresses and unstable servents, to
avoid keeping connecting to bad nodes.
* The download pane now shows how many items are actively and passively
queued.
* The search pane allows one to hide hits that are either ignored or
which have been already queued up by the core due to a matching SHA1
or filename.
* The "Purge" button could be hidden due to long filenames (#770625).
* A duplicate free() problem was fixed in _search_send_packet() (#706014).
* The "Purge" button doesn't cause crashes any longer (#757276).
* The bug which could cause a crash when resuming a download was fixed
(#739262).
The following changes affect only the GTK+ 2.x front-end:
* XFT support is not turned off by default.
* The node and the uploads panel have been tuned (a little).
* No more crashes if the uploads are sorted by status.
* Non-UTF-8 encoded strings were passed to GTK+ 2.x causing warnings
(#769342).
The following changes affect the build system:
* Switched to metaconfig, and abandonned autoconf/automake. There may
be some portability issues introduced on non-linux system since there
are lots of new metaconfig units that had to be developped for the
configuration of GTKG. In the long run, it will catch up.
* The "intl" directory containing GNU gettext() is no longer supported,
because it is currently only configurable via autoconf. If you don't
have proper GNU gettext() support on your system, you might have to
disable NLS support to be able to compile.
- (2003.08.10 - RAM)
* Replacement inet_aton() was using same parameter and local variable names.
* [GTK2] Integrated GUI update from Andrew Barnert, propagating changes
made to the GTK1 interface.
- (2003.08.09 - RAM)
* Switched to metaconfig.
- (2003.08.08 - RAM)
* [GTK1] Renamed "Abort all from host" as "Forget all from host" since we're
no longer paying attention to the "delete file on abort" setting here.
* Was unduly removing downloaded files when removing all queued download from
a host on timeout when they had "delete file in abort" turned on.
* Allow them to abort/forget a download when it is in "Sinking" mode.
* Moved GUI callbacks for upload stats to new upload_stats_cb.c.
* Fixed config_comment() to have readable and nicely-formatted comments.
* Updated the French translations.
* [GTK1] Changed label to "Report an upload connection speed of" to avoid
confusion on asymetric lines.
* [GTK2] Applied Emile le Vivre's update.
* Applied update from Stephane Corbe and reran autogen.sh.
* Added 64.15.0.0/255.255.0.0 to the list of hostile IPs.
* Manually patched generated po/Makefile.in.in and Makefile.am because of
crappy auto* tools: it would not build on my machine, yet those files
were generated/updated!
- (2003.08.07 - RAM)
* [GTK2] Integrated Emile le Vivre's patch adding support for the two
"node_monitor_unstable_ip" and "node_monitor_unstable_servents" properties.
* [GTK1] Added GUI configuration for "checkbutton_auto_feed_dmesh" and
"checkbutton_fuzzy_filter_dmesh" in the Config/Downloads pane.
* [GTK1] Reworded text for the checkbox controlling "auto_download_identical".
* When they don't monitor unstable IPs, gray out monitoring of unstable
servents in the GUI.
- (2003.08.06 - RAM)
* Count actively and passively queued downloads.
* [GTK1] Display actively and passively queued downloads.
* Obsoleted "mark_ignored": only retained for GTK2, and replaced with
"search_handle_ignored_files" for GTK1.
* Can now prevent display of search results that will be ignored.
* [GTK1] New combo to handle ignored files: 3 choices: display / mark / skip.
* Also consider 172.31/12 as a private IP range, and 255/8 as unroutable,
instead of just 255.255.255/24.
* Ooops -- 172.31/12 does not exist as a defined private IP range!
- (2003.08.05 - RAM)
* Forgot to customize the HTTP async layer when we're using the IP
swapping hack for client-side push proxy.
* After having swapped the IP, reswap it back before reporting failure to the
download layer.
* Don't display negative uptimes, force 0.
* When computing the remote node's uptime, use our clock offset to correct
the remote timestamp.
* Default for "nodes_monitor_unstable_servents" is now FALSE.
* [GTK1] Turned on gettext support in glade.
* [GTK1] Added GUI settings for the "node_monitor_unstable_ip" and
"node_monitor_unstable_servents" properties in the Gnutella config pane.
* [GTK1] New "Hide downloaded files" setting in Search to control display
of entries that were auto-downloaded already.
* New "search_hide_downloaded" GUI property.
* Don't show them auto-downloaded files if they don't want to see them.
* Plugged the necessary tieing update logic for the update of the three
new checkboxes.
- (2003.08.04 - Jeroen)
* 'Banning' of unstable servents and IPs is optional now using the
node_monitor_unstable_ip and node_monitor_unstable_servents config
settings which defaults to TRUE. node_monitor_unstable_servents
won't work when node_monitor_unstable_ip is disabled though.
- (2003.08.04 - RAM)
* Made a distinction between "connection timeout" and "data timeout" for
asynchronous HTTP requests.
* More endianness IP fixes.
* If we can't connect to a push-proxy, try swapping the IP as a temp hack.
(legacy servents were sending the IP in little-endian form in GGEP "PUSH".)
- (2003.08.03 - RAM)
* Only compute the "escaped filename" for downloads once, not at every
saving of the download queue.
* Added two new properties: "node_monitor_unstable_ip" and
"node_monitor_unstable_servents".
* Forgot one more instance where writing of IP address was incorrect (the
IP in the GGEP "PUSH" extension).
* Reverted Christian's optimization of timestamp emitting on log messages:
now always emit the timestamp on messages, otherwise it is a major pain
when grepping through logs and trying to correlate events, or simply
whem montitoring a logfile via "tail -f log | grep pattern".
[Fixes bug #778183]
* Fixed query_make_word_vec(), changed by Christian to make the first
argument a const: it was not filling the vector at all when there was
only one word in the query.
* Now tells them exactly why they were denied a Gnet connection.
* Fixed computation order for bw_max to avoid integer overflow.
* Added url_params_xxx() routines to get parameters in URL query strings.
* Added support for the "file=" parameter in push-proxies.
* Removed all the code that dealt with legacy 0.4 servents.
* Now that 0.4 support is gone, there cannot be any "ponging" connection.
* Editing pane for filtering "flags" rules had fixed hardwired values for
the "Mark only" and "Active" checkboxes instead of the current rule's ones.
- (2003.08.02 - Jeroen)
* PARQ was banning an IP pernamently instead of max 20 minutes.
- (2003.08.02 - RAM)
* Rolled back invalid change wrt reading/writing of IP addresses from/to Gnet.
* Added magic number at the head of the cproxy structure.
* Was writing the IP addess in LIME/22v2 as a 16-bit quantity!
- (2003.08.01 - Jeroen)
* When an IP got banned by PARQ, it won't be added to the upload
list anymore
- (2003.07.30 - Jeroen)
* PARQ will now treat servents which do not honour the Retry-After header
as hosts which are hammering the connection
- (2003.07.29 - Jeroen)
* Increased dbg level for ultrapeer client/ip 'banning'
- (2003.07.27 - Jeroen)
* Downloads through a push proxy should no longer crash gtkg due to
download_clone
- (2003.07.22 - Jeroen)
* Fixed path array in gwebcache.c when in unstable mode.
- (2003.07.21 - guruz)
* Added giFT vendor code
- (2003.07.20 - Jeroen)
* Try to avoid to connect to unstable ultrapeer hosts. An ultrapeer
is marked unstable when we are unable to connect to it for more
than 2 hours
* Initial import of tigertree source code.

new READ_GUINT16_BE() and WRITE_GUINT16_BE() supporting macros, required
by "PUSH".
* Changed signature of download_new() and download_auto_new() to include
the known push proxies.
* Moved search_gui_got_results() to search_gui_common.c
* GUI now uses gnet_host_vec_t instead of host_vec_t: no need to make a
particular data structure.

in query hit records.
* Not only refuse to add private IPs in the mesh, also refuse multicast et al.

* Further factorized code into search_gui_common.c: search saving / restoring.
* Rename XML searches as .orig before parsing.
* Switched GGEP "H" support indication from bit 12 to bit 11, since bit 12
is used for leaf-guided queries.
* Handle retry-after time on a per-download basis, not only on a per-server
one because of PARQ: we might need to retry one particular download earlier
than the others queued on the same server.
* The download "waiting" list is now sorted by increasing download retry time.
* Processing of EXT_T_URN_BITPRINT in query hits was incorrect.
* Added processing for GGEP "u" and "T" extensions in query hits.
* Will now protect against a query hit record having several SHA1, to avoid

- (2003.07.15 - Jeroen)
* Made search_gui.c compilable again when xml was disabled

- (2003.07.13 - Jeroen)
* PARQ won't assert on bad behaving clients anymore
- (2003.07.13 - RAM)
* Fixed ban_record(): could be using the wrong callout queue callback.
* Added ban_is_banned() to allow checking for the ban status without calling
ban_allow() which is only supposed to be called on new connections.
* When host refuses that we download from it, ban it for some time and kill
all its pending uploads.
* Don't send back QUEUE to a host that is banned.
* Protect against subsequent ban_record() calls: free existing ban mesasge.
- (2003.07.12 - Jeroen)
* PARQ doesn't like it when gets multiple requests for the same file from the
same host while it is allready being upload to that host. Duplicate upload
detection is now done before handing the upload over to PARQ.
* PARQ now keeps track to an upload structure so it can look up information
faster, as well as testing parq <-> upload integrity
- (2003.07.09 - Jeroen)
* PARQ: Uploads->parq pointers were only assigned during parq_upload_create.
Pointer is now also set when a existing parq upload is rerequested.

* Added -mieee to the compile flags when building for Debian on Alpha
[Patch from Christoph Reichenbach on Debian].
* Raised default gnet connection timeout to 10 seconds.
* Now fully supports special "min speed" field in queries. The GUI min speed
value as well as the default min speed are now ignored and should be removed.
* We now have the IP address in version checks: log it when bad token is seen.
* Added string evaluation code, that can evaluate ~/foo and $HOME or ${HOME}.
* Added new generic prop_name() to convert a property into its name.
* Property initialization strings are now run through eval_subst() to allow
environment variables and ~ in their value.
* Factorized setting callback for file path into one file_path_changed(),
and added a verification callback for PROP_BAD_FILE_PATH.
* Simplified debugging code to use new xxx_prop_name() calls.
* File path properties have their default set to "~" instead of "/tmp".
* Call locale_to_utf8() on filenames for GTK2 [Patch from Uriel].
* Also "broadcast" our own Push requests if we have multiple routes.
- (2003.07.05 - RAM)
* Parse all query hits for inclusion into the download mesh.
* Don't activate the "no keepalive" flag on downloads if we detect that
the server is performing some kind of "rotation" in the queue by closing
our connection after having shrunk our request.
* Prefix user-agent strings with a '*' when server appears to be banning us.
* Only use an IP for clock skew computation once per 24 hours.
* Apply queue regexp search to both download's filename and output filename
[Patch #754923 from Stephane Corbe].
* [GTK1] Print message in statusbar showing how many downloads were created
from the many items selected.
* Don't use GNU-isms for variadic macros, prefer the ANSI way
[Patch #755639 from int_80h].
* Avoid duplicate free in _search_send_packet() when empty word vector
(fixes #706014).
* Don't send queries unless there is a route for the possible replies.
- (2003.07.04 - RAM)
* Added anti-403 "Network Disabled" code.
* Don't insert alt-locs pointing to hostile IPs in the mesh.
* Navigation pane updates correctly with 'jump to downloads' (fixes #612799
and #629299) [From Emile le Vivre].
* When banning due to vendor user-agent string, record the IP and forcefully
ban it for 3 hours from then on, to defeat GTKG's own anti-banning code.
- (2003.07.03 - Jeroen)
* PARQ: Should only actively queue one upload per ip
- (2003.07.01 - RAM)
* Sort by size, then by SHA1 when sorting by size [From Thomas Schuerger].
- (2003.06.28 - RAM)
* Added "torrent" to the default list of sharing extensions.
- (2003.06.25 - RAM)
* Don't pick a suspended download in download_find_waiting_unparq().
* Asserted that a verifying download must be in DL_LIST_STOPPED.
* Mark fileinfo database as being dirty when a fileinfo is reset.
* Code cleanup in parq.c.
* Send blanked GUID in vendor messages that don't need a particular GUID.
- (2003.06.25 - Jeroen)
* PARQ: QUEUE callback should now also 'help' activly queued downloads
(untested)
- (2003.06.24 - cbiere)
* [GTK2] Re-worked removing of rows. Due to enabled sorting it seems to be
possible that a list store contains the same row twice. I consider this
a GTK+ bug, thus the changes are a bug workaround. The important part is
setting the data column to NULL to prevent accessing already freed data.
- (2003.06.22 - Jeroen)
* PARQ: Only sends one QUEUE command per IP at once. And aborts any other
pending QUEUE callback for that IP if the first one can't connect
- (2003.06.19 - RAM)
* Optimized server banning test.
* Don't send pong-cache pings on a flow-controlled connection.
* Finished application of Angelo's symlink patch (fixes bug #756146).
* Restored stripped out gtk_init(&argc, &argv) call (fixes bug #757504).
* Moved verify_close() and move_close() calls before main_gui_shutdown()
so that no ticks to the daemon thread be made whilst in shutdown!
- (2003.06.17 - Richard)
* [Gtk2] No longer disable antialiasing. This confuses people who are
using Gtk2 and get font problems. If they want better performance, they
should turn off AA manually using "export GDK_USE_XFT=0".
(closes 754998).
- (2003.06.17 - RAM)
* Now supports collection of multiple URNs from X-Gnutella-Content-URN,
but still only look at ones containing a SHA1.
* Use new dmesh_collect_sha1() to collect URNs.
* Collect URNs from non-standard Shareaza X-Content-URN header.
* When remote host turns out to be a genuine GTKG, stop anti-banning
protection by faking a user-agent string, since we know the remote end
won't be discriminating us.
# v 0.92 2003.06.15 [stable]
- Now supports Ultrapeers, which means GTKG can work as an ultra node or as
a leaf node. You can still run as a normal node, although this is not
something wise to do, because that will likely relagate you in a small part
of the Gnutella network.
- New icons for showing node state (leaf or ultra mode).
- The GTK2 front-end is no longer experimental, albeit it is slower than
the GTK1.2 front-end. This is due to the somewhat inefficient
implementation of the underlying GTK library. Don't use GTK2 unless you
have the equivalent of a 1 GHz Intel chip.
- Added client-side PFSP support (partial file sharing). GTKG can download
from servers holding partial files.
- Added full PARQ support (Passive / Active Remote Queuing), both for uplaod
and downloads.
- New Gnet statistics: flow-controlled packets per TTL and hops.
- The "Type" column in the Gnet connection pane was turned into "Flags".
- Added support for GGEP in pings/pongs/pushes: those packets are now
accepted and forwarded to connections advertising GGEP support.
- New "use surplus bandwidth" setting: all unused bandwidth for Gnet or HTTP
can be stolen by the other in case it needs some.
- Added count for total bytes uploaded and downloaded.
- Added support for vendor-specific messages.
- New hops-flow support: remote flow-controlled connections can now warn us
that thye are flow-controlling us, and so we can drop queries immediately
instead of sending them, saving outgoing bandwidth.
- Will now show the GTKG version in query hits.
- The queue now shows the count of alive downloads, as well as the queue count.
An "alive" download is an entry for which the remote server replies.
- Changed the connection algorithm: will now attempt to connect to more
nodes than really configured, dropping the surplus connections later, when
needed at all.
- Filters out hostile IP addresses.
- New "fileinfo" pane in the download screen. Not finished, but will show
the currently registered downloads and their status.
- Domain name resolution for Gnutella web cache are now done asynchronously.
The GUI will no longer freeze due to a DNS request.
- Some performance improvements: removed the most important bottlenecks.
- (2003.06.14 - RAM)
* Updated hostiles.txt to follow BearShare's modifications, and sorted it.
* Forgot to mention PARQ id in header of persisted downloads.
* Changed tooltip for "listen_port".
* The new default listening port is now set to 8436 to avoid ISP censorship.
* Fixed typo appereance -> appearance in GTK2.
- (2003.06.12 - Jeroen)
* PARQ: Max uploads from single host is also detected and used in PARQ now.
* PARQ: Timesout small upload chunks sooner now. This should make sure people
who were unable to have all there upload slots used before, because
they were only sharing relative small and popular files, to maximize
their bandwith usage again if they want. This shouldn't affect PARQs
behaviour for small files.
NOTE: This is: #if 0 in the parq code, and thus actually disabled.
* PARQ: No more assertion failure on gtk-gnutella shutdown (I hope)
- (2003.06.10 - RAM)
* Don't send out an invalid IP/port in the X-Node header.
* Integrated GTK2 icon patch [From Russell Francis].
- (2003.06.09 - RAM)
* Raised default amount of downloads from 10 to 50.
* Doubled max PARQ retry time, and lowered retry frequency for queued entries.
* Fixed English: SHRINKED -> SHRUNK.
* Avoid endless request/sinking loops: only allow one sinking per session.
* Added some extra assertions in PARQ, little cleanup.
- (2003.06.09 - Jeroen)
* PARQ: PARQ IP entries are now stored using their dotted notation.
* PARQ: Fixed: Slots by IP didn't work yet
* PARQ: Also preference by IP and not just by filename only. If client has
2 files A (pos 1) and B (pos 66) and it is requesting file B it will
still be allowed to upload. file A will have to wait for file B though.
- (2003.06.08 - Jeroen)
* Prefer compressed connections should now also work in Ultrapeer mode
* PARQ: Should not block anymore when a queued upload is not allowed to
continue due to 'max allowed uploads per ip'
- (2003.06.07 - RAM)
* Decode base32 case-insensitively.
* Fixed stupid memory leak: pmsg_free() called in a debug block.
- (2003.06.05 - RAM)
* Don't parse incoming X-Node headers for PARQ if requestor did not advertise
support for PARQ, since X-Node is not necessarily PARQ-specific.
- (2003.06.03 - RAM)
* Append a trailing '-' in the download range size indication when the server
is answering us with less data than we requested. The amount shown then
reflects what the server is giving.
* Don't store downloads to disk every time we abort/stop one. This should
improve speed noticeably when aborting by SHA1 or by server!
- (2003.06.02 - Richard)
* Applied symlink patch from Angelo Cano
- (2003.06.01 - RAM)
* Fixed download_clone() to remap the parq ID to the children download.
* Make sure to revitalize a stopped download upon receiving QUEUE.
* Removed spurious trailing "\n" in warnings from parq.c.
- (2003.06.01 - Jeroen)
* Uploads: HEAD requests won't be treated as a followup request anymore (which
avoids an upload to ignore the max uploads per ip setting)
* PARQ: Fixed an assertion failure when an upload got removed due to too many
disconnections
- (2003.05.29 - RAM)
* Top makefile did not install "hostiles.txt".
* Reset counter of QUEUE requests sent when remote servent replies to one.
# v 0.92 2003.05.25 [candidate]
Candidate 0.92 release. The following are the main changes since 0.92b2:
- PARQ is now fully implemented.
- Filters out hostile IP addresses.
- New icons for showing node state (leaf or ultra mode).
- New "fileinfo" pane in the download screen. Not finished, but will show
the currently registered downloads and their status.
- Minor bugs fixed.
WARNING: Leaf node bandwidth is now stolen from HTTP when running in ultra
mode. If that brings outgoing HTTP bandwidth to 0, sharing is disabled.
- (2003.05.25 - RAM)
* Miscellaneous cleanup before release of 0.92c.
* Now trace vendor string in the "Cancelling upload" messages.
* Mentionned in GUI hints that number of PARQ queue is governed by the
number of upload slots, and that it should be at least set to 2.
* Tell them that when host runs NTP, the computed clock skew is ignored.
* Display lifecount of the fileinfo, not its refcount [From Hans de Graaff].
- (2003.05.25 - Jeroen)
* When in leaf mode: Prefer compressed connections is honoured again.
- (2003.05.24 - RAM)
* Also package the pixmaps in the RPM [Patch #635484 from Sam Varshavchik].
* Don't store download queue at each download inserted [Patch #699251 from
Paul J. Mantyla].
* When ignoring a download due to an hostile IP address, make sure we don't
clear all the downloads for that file: it's just the server that we ignore,
not the download entry.
* Remember disabled searches when persisting (fixes bug #625314) [Patch
#739466 from Stephane Corbe].
* Increased max HTTP header size on reception to 16K.
* Cleaned up patch from Stephane Corbe.
* Added some assertions regarding fileinfo lifecount.
* Try to report a more specific message to servents mis-handling Retry-After
whilst passively queued.
* Include vendor string in PARQ warning messages about early retries.
- (2003.05.24 - Jeroen)
* PARQ: New ETA calculations. It now takes the current uploads into account too.
* PARQ: Don't save PARQ entries from which the upload was finished.
* PARQ: Avoid abusing: re-using the ID for another upload which got finished.
(a client could keep an upload slot for eternity)
- (2003.05.23 - RAM)
* Fixed punishing of hosts that re-request too early without paying attention
to the Retry-After header.
- (2003.05.22 - Jeroen)
* PARQ: A broken/disconnected upload can reclaim its queue position
* PARQ: Upload pane now shows the Queue the current upload is queued in
* PARQ: Dynamic upload slots also honours parq now.
* PARQ: Fixed: No more infinite Waiting uploads.
- (2003.05.20 - Jeroen)
* PARQ: Fixed: An upload can't get actively queued more than once at a time.
- (2003.05.19 - Jeroen)
* PARQ: Shouldn't assert anymore when using dynamic slot allocations
* PARQ: If a client does not obey the Retry-After header it will be
removed from the PARQ queue.
- (2003.05.19 - RAM)
* Forgot a "continue" statement in download_remove_file().
* Likewise, on a file info change, don't requeue actively queued downloads
or connecting ones.
* Make sure the message queue kept track of the right amount of items.
- (2003.05.18 - RAM)
* Added the @INTLLIBS@ macro in the linking flags for I18N
[From Christian Biere].
* Reset some fields to NULL in download_remove().
* Must ignore downloads marked as GTA_DL_REMOVED when iterating on the
download list.
* Don't call download_free_removed() from fi_purge(). That call must be
done asynchronously.
* Changed status type in uploads to upload_stage_t.
* Don't send the PARQ ID on 2xx for HEAD replies and follow-up requests.
* Added extra pre-condition to fi_purge().
- (2003.05.17 - RAM)
* Doubled half period for remote flow control computations to 5 minutes.
* Don't requeue actively queued downloads or connecting ones when the
underlying file is removed.
* When a download has PARQ information, don't stop it when a write to the
remote host fails, but requeue it instead. Those downloads have a chance
of being resumed.
* Renamed download_free() into download_remove().
* Clone lists before iterating in bg_close().
* Reverted to using casts in clock_update().
* Made clock_update() ignore the new timestamp if delta is within precision
(making the ignore interval 2*precision instead of just precision).
* Increased period for alive pings between ultrapeer and leaf to 120 seconds.
* Flag when we send a QUEUE, and determine whether they refused our callback.
After they refused it MAX_QUEUE_REFUSED times, we give up and never send
them a QUEUE during this session.
* Added parq_upload_add_header_id() to add an X-Queued header on 2xx replies.
* Always call parq_upload_remove() from upload_remove().
* Plugged call to parq_upload_add_header_id() to send queue ID on 2xx replies.
* Renamed upload_push_conf() as upload_connect_conf().
* Added call to parq_download_parse_queue_status() even on 2xx replies.
* Call parq_upload_add_header_id() before upload_http_status() to avoid
lacking room in the headers if alternate locations are present.
* Remember when a PARQ id was sent, to avoid sending one back on 2xx replies.
* Fixed assert failure in ban_force() when only 1 fd is used for banning.
- (2003.05.16 - RAM)
* Limit clock skew to one day maximum: avoid badly synchronized remote clocks
to let the skew deviate out of proportions.
* Avoid issuing a connection to a node we're already connected to
[From Rafael R. Reilova].
* GTKG could loop in malloc(): block was freed twice in the case a config
file was retrieved from the .orig version.
* Ignore SIGQUIT in the adns process, so that CTRL-\ makes GTKG dump a core.
* Must call parq_init() before retrieving the downloads now that PARQ IDs
are stored.
- (2003.05.15 - RAM)
* Allow server to give a smaller range than the one we're requesting.
* Reject download when range end is greater than what we asked for.
* Persist download PARQ ids.
* Added download_find_waiting_unparq() to elect replacing download on QUEUE.
* Fixed handling of QUEUE callbacks: was not parsing the ID correctly.
* When looking up a PARQ download by ID, if we don't find one for the host,
try to pick any non-PARQ waiting download for that host instead.
* PARQ ids are now random GUIDs, tagged for GTKG.
* Don't call file_info_update(DL_CHUNK_EMPTY) to clear the tail of a range.
The routine is not prepared to handle that case. As a workaround,
call file_info_clear_download() first, then file_info_update(DL_CHUNK_BUSY)
on the complementary part.
* New file_config_open_read_norename() to open config files that are never
written, and which therefore don't need to be renamed as ".orig".
* Fixed file_config_open_read() so that it displays "instead" when we open
the ".orig" version.
* Fixed file_info_update() so that it accepts DL_CHUNK_EMPTY on *whole* ranges.
* Open hostiles and whitelist with new file_config_open_read_norename().
- (2003.05.15 - Jeroen)
* PARQ: Don't display status Waiting when there are no upload slots available
* PARQ: Send a QUEUE command when an upload slot is available
- (2003.05.14 - Jeroen)
* PARQ: Saves and loads the expiration time of a queued upload. This should
speed up starting uploading on startup.
* PARQ: Fixed an assertion bug in upload_timer
- (2003.05.13 - RAM)
* Avoid casting to (gint32), and use the "* (gint32*)" dereferencing trick.
* In the download pane, display ETA for queued entries in a readable way.
* Forgot to make a variable "static", causing endless promoting and demoting
to/from ultra mode.
* Fixed memory leak in sq.c, when query is ignored.
- (2003.05.12 - RAM)
* Stopped removing half the slot contribution to writing b/w schedulers for
all the slots that don't trigger.
* Added missing RCSID to hostiles.c.
- (2003.05.12 - Jeroen)
* PARQ: Fixed an assertion when connecting back to another IP than the IP
the upload connected from.
-(2003.05.11 - Richard)
* [Gtk1] Added clock skew to gui (calculation seems broken).
* [Gtk1] Added PROP_RUNS_NTP to gui.
* [Gtk1] Reordered connection settings in gnet pane.

ultrapeer setting in legacy mode.
* Changed displayed info when failing to load config files.
* Properly update PROP_CLOCK_SKEW instead of modifying the variable directly.
- (2003.05.11 - RAM)
* Updated PARQ to revision 1.0.a of the specs.
* Added flags to record whether a QUEUE is pending.
* Try sending as many QUEUE messages as possible until we have 100 uploads.
* Don't expire a PARQ entry if a QUEUE message is pending but was delayed
because there are too many uploads running.
* Exported download_redirect_to_server() for PARQ.
* Send QUEUE messages spaced by at least 10 minutes for a given entry.
* Give dead downloads a chance to come back to life by sending them QUEUE.
- (2003.05.10 - Jeroen)

* New -DTRACK_ZALLOC compilation switch that will track down the allocation
points of all the zalloc blocks to display leaks at the end.
* New properties "host_runs_ntp" and "clock_skew".
* Will now try to automatically figure out the clock skew relative to GMT.
* Use the Date: HTTP header as a source for clock skew computation.
* Use token timestamps as another source for clock skew computation.
* Trace Ultrapeer selection criteria for debugging.
* Made sort order in the search pane persistent (fixes bug #557696) [From
Emile le Vivre].
* Was not using the forced 95% threshold for flow-control limits in leaf mode.
- (2003.05.09 - RAM)
* Accidentally inverted condition for hostile checks on pongs: was dropping
all the non-hostile pongs as being hostile!

- (2003.04.16 - RAM)
* Added new "configured_peermode" property. Old "current_peermode" is
no longer persistent.
* Leaf node bandwidth is now stolen from HTTP. If that brings outgoing
HTTP bandwidth to 0, sharing is disabled.
* Reordered the computations in bsched.c: resort to early floating point
division by 1000.0 then to multiplication to avoid overflowing integers.
* Shut up compiler warning about uninitialized var in adns.c.
* Removed "force_ultrapeer" and "force_leaf" properties.
* Addded automatic promotion of leaf to Ultrapeer based on uptime (for now).

# v 0.92 2003.03.04 [beta2]
Bugfixing release:
- Fixed Gnutella web cache hammering. A buggy test caused GTKG to query
the caches each time it was establishing an outgoing connection!
- Domain name resolution for Gnutella web cache are now done asynchronously.
The GUI will no longer freeze due to a DNS request.
- Some performance improvements: removed the most important bottlenecks.
- Fixed flow-control bug, exercised mainly with compressed connections: they
could stall abruptly, no longer transmitting data.
- Fixed assertion failure in PARQ client code.
- Fixed incomplete clearing of downloads from a given host.
- (2003.03.04 - RAM)
* Ban 0.92b as an hostile servent, due to its GWC hammering.
* Only emit the exec() argument size warning if lib_debug.
* Fixed version_tagcmp(): was not anti-symetric for 'b' and 'u'.
- (2003.03.03 - RAM)
* Optimized guid_eq() and sha1_eq() to not call memcmp().
* Rewrote the callout queue to have a more efficient ev_link() routine, the
drawback being a slightly more costly cq_clock() call.
* Fixed GWC hammering bug.
* Avoid using / and % in macros from idtable.c.
* Removed spurious trailing "\n" in some warnings.
- (2003.03.02 - cbiere)
* [GTK2] gtk2-gnutella.glade:
Added spinbutton_config_track_props (sync with GTK1)
main_window_config_sel_tab: center contents
* oldconfig.c/config_set_param(): Translate proxy_connections to
proxy_protocol=PROXY_NONE from old config files
* sockets.c/socket_connect_prepare():
Moved ip parameter to socket_connect_finalize()
* sockets.c/socket_connect_finalize():
Fixed typo: addr <-> lcladdr
Added another memset() to clear lcladdr
Don't call socket_destroy() if the function was called from the
ADNS callback which would cause a second socket_destroy() later
* sockets.c/socket_connect_by_name_helper():
Don't call socket_destroy() but set SOCK_ADNS_FAILED in case of an error
* sockets.c/socket_connect_by_name():
If the callback for adns_resolve was already invoked, check the status
and call socket_destroy() in case of an error
* sockets.h/struct gnutella_socket:
Replaced `gboolean adns_pending' with `gint adns' as status variable
Added `adns_msg' which should point to a static error message when
SOCK_ADNS_FAILED is set, points to NULL otherwise
* Removed all GDK legacy from core i.e., s/GDK_INPUT/INPUT_EVENT/ and
no #include <gdk/gdk.h> any longer
* Applied patch by Murphy <juncus@telus.net> which fixes typos in tooltips
* nodes_cb(2).c: Added add_node_helper() for proper type translation
* adns.c:
Use adns_callback_t instead of a lazy gpointer
Revised client-side to use non-blocking pipes which prevents
deadlocks, allows partial transfers and to handle filled
pipe buffers
* adns.c/adns_resolve(): Returns FALSE if the resolution happened
synchronous, otherwise returns TRUE.
- (2003.03.01 - RAM)
* Show that we sent crawler info when remote disconnects after our reply.
* Fixed assertion failure when parsing PARQ replies.
* Added gm_setproctitle().
* The ADNS subprocess will now be identified by "ps" as the "DNS helper".
* Changed socket_timer() to avoid removing entries whilst iterating on list.
* Special case the insertion to an empty array in qlink_insert().
* Avoid uninitialized memory reads by bind(): zero the addr structs.
* Forgot to free the list in socket_timer().
- (2003.02.28 - RAM)
* The `dl_by_time' list was split into a hashed array, to cut down the number
of item comparisons we do when inserting, at the cost of more work when
traversing the list.
* Optimized filter_apply() by pre-computing the length of the matching text
at filter "compilation" time, to avoid endless strlen() calls.
* Optimized search_has_muid(): sent MUIDs are now stored in a hash table.
* Turned old g_return_if_fail() from legacy code into a g_assert() (tx_link.c).
* Added some debugging traces whilst chasing the "connection freeze" problem
(tx_deflate.c).
* Fixed mq_service(): need to saturate the lower layer whilst running, lest
we run the risk of never being called again when the lower layer has
finished flushing its data => the TX side freezes.
- (2003.02.27 - RAM)
* Optimized message queue to avoid huge CPU utilization during flow-control.
* Optimized mq_service() to avoid useless I/O vector building.
* Don't encode '/' in the query portion of URLs.
- (2003.02.27 - Richard)
* event.[ch]: Added as a replacement for listener.h. For now it's used only
in the property system. The bonus over listener.h: control of callback
frequency on a per-listener base.
* Added seperate property to control debug level of the property system.
* props.tpl: Upgraded to use event.[ch], regenerated property sources.
* prop.[ch]:
- Upgraded to use event.[ch]
- Added prop_get_by_name(): look up a property by name.
- Added prop_to_string(): converting a property to string reprsenentation,
doesn't work for all property types yet.
* settings_gui.c: Upgraded property_map to make use of the new frequency
control feature of prop.[ch]
* shell.c:
- No longer show auth cookie in debug output
- New command: "PRINT [property]" to display current value of a property
- (2003.02.25 - RAM)
* Added CRC32 code.
* Fixed the base32/base64 code to correctly process padding, and return the
amount of decoded bytes, padding not included.
* Some servents send X-Try headers at every handshaking step, so process them.
* Added token level.
* Restored old ban_vendor() signature.
- (2003.02.23 - cbiere)
* adns_do_transfer(): forgot to rename write to do_write
* adns_gethostbyname(): use host_to_ip() instead of gethostbyname()
* adns_callback(): remove the callback manually because the relay in
inputevt.c doesn't propagate the return value;
close() pipe if adns_do_read() fails
* adns_init(): close() stdin and wire the file descriptor to /dev/null,
just in case because it's shared with the main process;
use _exit() instead of exit();
close() all opened file descriptors in case fork() fails
* adns_resolve(): close() pipe if adns_do_write() fails and don't retry
* main(): ignore SIGINT and SIGPIPE before adns_init();
use sig_ignore also for SIGXFSZ
* host_to_ip(): declare hostname as const
* upload_write(): Hide variable "pos" if HAVE_SENDFILE is undefined
* adns.c:
* Added caching; caching happens server-side, if the server dies
* caching will be started client-side;
* Fixed typo (children -> child);
* Debug warnings depend on dbg > 1 or dbg > 2, now;
* Declared larger variables as static;
* adns_resolve(): usage of fallback is only reported once
* [GTK2] locale_to_utf8: moved function from misc.[ch] to utf8.[ch]
- (2003.02.23 - RAM)
* Forgot to negate the return of version_check().
* Partially validate version whose token is given.
* Avoid always polling at the minimum specified by the download server.
* Applied Christian's patch fixing the type of gtk_tag and inputevt_add().
* Forgot to use network order when writing token's timestamp.
- (2003.02.22 - guruz)
* Added MLDonkey vendor code (MLDK)
- (2003.02.22 - cbiere)
* The user_callback (parameter for adns_resolve()) was called twice if
the hostname was an IP string; this caused s->gdk_tag != 0 in
socket_connect_finalize() because it was called twice due to this bug.
- (2003.02.21 - cbiere)
* Added socket_connect_prepare() to reduce double code
* Added adns_pending to which indicates whether the adns callback has been
invoked
* Added socket type SOCK_TYPE_DESTROYING which is used free the socket after
the adns callback has been invoked; prevents accessing already free()d
memory.
* Replaced assertion in socket_connect_finalize() because an event handler
might have been installed while resolving the hostname; this is only a
temporarily work around and not a solution!
- (2003.02.21 - RAM)
* Integrated Christian Biere's ADNS patch (fixes bug #662916).
* Now uses G_N_ELEMENTS() to determine the amount of items in array.
* Added version tokens.
- (2003.02.17 - RAM)
* Would not remove all the downloads from a given host sometimes.
- (2003.02.15 - RAM)
* Associate download with move context early in case we cannot create the
file on the filesystem: d_end() processing must still be able to run.
- (2003.02.11 - RAM)
* Forgot to add the "sinking" state to the ESTABLISHING macro.
* Don't lead them to the leaf status if we can't accept leaves.
# v 0.92 2003.02.08 [beta]
Highlight of changes (user-visible):
- Now supports Ultrapeers, which means GTKG can work as an ultra node or as
a leaf node. You can still run as a normal node, although this is not
something wise to do, because that will likely relagate you in a small part
of the Gnutella network.
- The GTK2 front-end is no longer experimental, albeit it is slower than
the GTK1.2 front-end. This is due to the somewhat inefficient
implementation of the underlying GTK library. Don't use GTK2 unless you
have the equivalent of a 1 GHz Intel chip.
- Added client-side PFSP support (partial file sharing). GTKG can download
from servers holding partial files.
- Added client-side PARQ support (Passive / Active Remote Queuing). GTKG
can now queue downloads from either active-queuing servers or PARQ.
- New Gnet statistics: flow-controlled packets per TTL and hops.
- The "Type" column in the Gnet connection pane was turned into "Flags".
- Added support for GGEP in pings/pongs/pushes: those packets are now
accepted and forwarded to connections advertising GGEP support.
- New "use surplus bandwidth" setting: all unused bandwidth for Gnet or HTTP
can be stolen by the other in case it needs some.
- Added count for total bytes uploaded and downloaded.
- Added support for vendor-specific messages.
- The "prefer compressed connections" settings no longer works as expected
when running in non-normal mode.
- New hops-flow support: remote flow-controlled connections can now warn us
that thye are flow-controlling us, and so we can drop queries immediately
instead of sending them, saving outgoing bandwidth.
- Will now show the GTKG version in query hits.
- The queue now shows the count of alive downloads, as well as the queue count.
An "alive" download is an entry for which the remote server replies.
- Changed the connection algorithm: will now attempt to connect to more
nodes than really configured, dropping the surplus connections later, when
needed at all.
WARNING:
- The amount of bandwidth configured for leaves is currently automatically
added to the HTTP connections when not in leaf mode, regardless of whether
"use surplus bandwidth" is activated. This will change in the release.
- (2003.02.08 - RAM)
* Fixed memory leak in gwcache.c.
* Refactored upload_stats_dump_history(), and added upload_stats_close().
Cleanup and dumping are now clearly separated.
* Suppressed settings_upload_stats_save(): there is no an explicit call
to upload_stats_close() done at exit time.
* Be sure to call bsched_set_peermode() each time a bandwidth value is changed
so that we can adjust the schedulers according to the current mode.
* New FALSE default for the "fuzzy_filter_dmesh" property.
* When downgrading from ultra to leaf mode due to peer request, be sure to
use the property system to change the "current_peermode" property, instead
of writing directly to the variable!
* Make sure we react to the peermode change asynchronously.
- (2003.02.07 - RAM)
* Fixed memory leaks in dmesh.c, fileinfo.c, qrp.c.
* Allow user to abort actively-queued downloads.
* Added upload_stats_free_all() to clean up memory on exit.
* Fixed reading of free'd memory in mq.c.
- (2003.02.06 - RAM)
* Had mistakenly added the "sinking" state to DOWNLOAD_IS_ACTIVE().
* Prefix all warnings with a timestamp [From Christian Biere].
- (2003.02.05 - RAM)
* Fixed dmesh fuzzy matching memory corruption.
* Send PUSH messages at max TTL value, not my TTL in case it needs re-routing.
* Added missing memory cleanup to shutdown calls, preventing leak detection.
- (2003.02.04 - RAM)
* Abort download if handed out an URL that is too large (probably garbage).
* Integrated fuzzy dmesh filtering for non-N2R entries [From Alex Bennee].
* Shortened the string displayed for queued download entries.
* New properties "pfsp_server", "pfsp_first_chunk" for PFSP (unused for now).
* New property "fuzzy_filter_dmesh" to toggle fuzzy dmesh filtering.
* Give unused reserved bandwidth for leaf nodes to HTTP traffic.
* Integrated fix in get_header_value() [From Jeroen Asselman].
- (2003.02.03 - RAM)
* Added inclusion of "common.h" for FreeBSD 4.7 (utf8.c).
* Integrated PARQ patch: client-side is fully supported [From Jeroen Asselman].
* Raised minimal query routing table size to 128 K slots, and lowered the
sparseness and conflict ratios to check whether we can double the routing
table size.
- (2003.02.02 - RAM)
* No longer free remaining atoms in atom_warn_free(), for leak detectors.
* When seeking to get the fileinfo trailer, don't use SEEK_END with a
negative offset, but use SEEK_SET with an explicit positive value to
avoid problems when off_t is 8-byte wide [From Christian Biere].
* When doing SEEK_SET, check that lseek() returns the right offset.
* Be sure to not truncate the headers for crawler replies in the middle
of an IP address [From Christian Biere].
* Fixed final cleanup in pcache.c to also discard the recent pong cache.
* Changed freeing order for the existing query table when a RESET is received.
* Protect against broken servents that don't send us QRP patches covering
the whole query table.
* Fixed memory leak on the query sending path in ultra mode.
* Made sure `n' is no greater than INT_MAX for gm_*snprintf() calls.
* Don't forget to reset str[0] to NUL in case we have to strlen(str) within
the gm_*snprintf() calls.
* First experimental support for PARQ (active queuing only, client-side)
[From Jeroen Asselman].
* Fixed parq_download_add_header(): now gets length of buffer explicitly.
* Fixed status display for remotely queued entries.
* Fixed get_header_value() to look for a ',' separator as well.
- (2003.02.01 - RAM)
* Limit lifetime of download mesh entries to 1 day.
* Added pre-condition to file_info_find_hole(): no busy chunks for download.
* Forbid outgoing connections to a Gnutella crawler.
* Apply vendor-specific banning early, so banned people know about it even
if we're otherwise busy.
* Limit the headers sent back to crawlers to the strict minimum.
* Replaced all broken g_snprintf() and g_vsnprintf() calls by calls to
fixed gm_snprintf() and gm_vsnprintf(). Broken calls are now forbidden.
* configure now looks for vsnprintf() and defines HAVE_VSNPRINTF.
- (2003.02.01 - Richard)

- search_cb.c, search_cb2.c: show "none auto selected" in the status bar
when no additional results were autoselected
- (2003.01.30 - RAM)
* Immediately reset the qrt_ fields and query_table to NULL after having
freed those items, to prevent accidental reuse.
* Forgot to remove QRT patch compression task from the list of running tasks
upon a cancel.
* Clone directory list before traversing it with recurse_scan() since we
loop back to the GUI and the directory list could be changed whilst the
scanning is proceeding.
* Suppressed warning about handle_messages_supported() not being done.
* Removed spurious assert() in qrt_patch_computed_add_listener().
* Added support for LimeWire's crawler.
- (2003.01.29 - RAM)
* If downloaded filename is empty, use "noname" as the filename.
* Forgot to test for swapped ranges in the trailing range listed.
* Fixed bug when cancelling QRT computation due to rescanning.
* Fixed another bug when cancelling QRT computation due to rescanning.
* Tell whether we're an ultranode or not on handshaking errors.
- (2003.01.27 - RAM)
* Will now show when a download is from a partial file, and how much of
the total file the remote server has.
* New http_range_size() routine.
* Now makes sure ranges are well-specified before calling http_range_add().
* Also detect overlapping with next range in list during http_range_add().
* Changed detection place of so-called "gnutella2": will now abort earlier,
without giving the chance for the remote ultranode to become a leaf.
* Dynamic upload slot computation was not co-existing peacefully with
the ability to steal bandwidth: now compare both instantaneous and average
to the min usage percentage.
* Handle only the very first range in upload requests, instead of replying 500.
- (2003.01.26 - RAM)
* Added glib-missing routines.
* New HTTP range parsing routines.

- (2003.01.24 - RAM)
* Reworked the bandwidth stealing algorithm to behave less aggressively when
the kernel flow-controls us on the way out.
* Do not send out duplicate addresses in X-Try* headers.
* Fixed `elapsed' to be a time_t instead of a guint32 (http.c).
- (2003.01.19 - RAM)
* Must not free word vector if it was not allocated (matching.c).
* Update node flags after the first handshake reply.
* Only send about 50% of queries to flow-controlled leaf nodes.
* Understand specially marked speed in queries, but do not emit them yet.
* Warn users running an unstable version after 60 days, ban them after 90.
* Was not emitting X-Try-Ultrapeers correctly.
* New flag 'd' shown instead of 'F' when the queue is non-empty, to indicate
that there is some delay in the packets sent.
* Based on my experiments about the necessary bandwidth to run an Ultrapeer,
changed the default amount of leaves to 15 and the minimum to 5.
* Display max amount of leaves/ultra/nodes when rejecting connections.
* Added necessary callback from mq.c to warn when queue count changes, so
we can update the node's flag immediately.
* Was not parsing version tag properly, and therefore started to ban recent
stable GTKG versions.
* Do not trigger "activity timeout" for leaf nodes.
- (2003.01.18 - RAM)
* Added new properties: "bw_gnet_leaf_in_enabled", "bw_gnet_leaf_out_enabled",
"bw_gnet_lin" and "bw_gnet_lout" to control leaf node bandwidth.
Those are special: values configured are automatically added to Gnet
bandwidth when not in ultra mode, regardless of whether the shaper is
enabled.
* Set decent default Gnutella bandwidths.
* Added leaf bandwidth scheduler, that can steal bandwidth out of Gnet only.
* Reordered creation of TX and RX stack so that the peermode is known.
* Can now properly switch between all three modes (normal, leaf, ultra).
* Upon mode change, reshape the Gnet bandwidth (leaf versus regular).
* Added support for QRP infinity 1 to not rule out Shareaza.
* Have the TX and RX link layers write/read using proper bandwidth scheduler.
* Had inverted proportional bandwidth repartition computations.
* Adjusted the bandwidth scheduling algorithm to behave a little better
in the advent we lack bandwidth and lots of stealing occurs accross shapers.
* No longer kills a connection when the send queue becomes full, unless
the message was a prioritary one.
* RX and TX stacks now provides access to the underlying link-level I/O source.
* GUI now displays the node TX / RX speeds in k/s.
* Leaf nodes have their send buffer shrank to as low as 256 bytes.
* Doubled the time between two alive pings.
* Don't route the query if the hashing vector is empty.
* Don't send queries from the search queue on flow-controlled connections.
- (2003.01.18 - Richard)
* [Gtk1] Added following props to gui:
- PROP_SEARCH_MAX_RESULTS (search pane settings)
- PROP_NODE_RX_FLOWC_RATIO (gnet config quality management)
- PROP_NORMAL_CONNECTION (gnet config)
- (2003.01.17 - RAM)
* Added routing of queries based on QRT.
* Don't even try to insert in the search queue if hops-flow is set to 0.
* Don't put leaf node's address in the hostcache for crawler pings.
* Added highest_bit_set() routine.
* Lowered the minimum amount of leaves from 50 to 25.
* Refactored management of connections to be more aggressive when we
lack nodes and avoid turning incoming connections down too early
(closes 607268).
* Don't ping leaf nodes to get pongs from them.
* Avoid routing back a leaf node query to its sender.
* Forgot to free word vector built for query routing purposes.

- (2003.01.13 - cbiere)
* [Gtk2] Set encoding for GIOChannels to NULL which is safe to use with
binary data
- (2003.01.12 - RAM)
* Quote mesh URLs that contain the ',' character so other servents are
not confused (GTKG does not need this).
* Fixed skipping of trailing quote in URL parsing [From Alex Bennee].
* New properties "normal_connections", "node_leaf_count", "node_normal_count"
and "node_ultra_count".
* The leaf node mode is no longer experimental, but Ultrapeer mode is.
* Added Ultrapeer negotiation management (inter-ultra nodes and ultra / leaf).
* Is now lenient about TTL=0 messages sent from ultrapeer to leaf.
* Will ban ancient versions after 1 year only, instead of 1.5 years.
* First take at QRP reception message management (partially done).
- (2003.01.11 - cbiere)
* Fixed wrong date for ChangeLog
* Tried to pop non-existent message from statusbar
* [Gtk2] New locale_to_utf8: non-convertible characters are replaced by an
underscore ('_')
* [Gtk2] Downloads: Reenabled multi-selection
* [Gtk2] Gnet stats: Save and restore column widths; use pretty alignments
* [Gtk2] Nodes: Save and restore column widths
* [Gtk2] Search results: Stop autoselecting during shutdown phase;
Added status column; Sync column widths (still buggy but harmless);
Use highlighting;
* [Gtk2] Upload stats: Use custom CellDataFunc instead of invisible columns;
prepared save/restore for column widths (not complete yet)
- (2003.01.11 - RAM)
* New property "node_rx_flowc_ratio".
* Make sure we're not remotely flow-controlled too often.
* Replaced magical "7" with the new GTA_NORMAL_TTL constant.
* New property "dl_qalive_count".
* Downloads now update the "dl_qalive_count" to reflect the amount of
sources that still reply to our requests.
- (2003.01.10 - RAM)
* Was reading '*p' but could peruse 'c' instead (dmesh.c).
* Generalized the use of walloc/wfree for small structures.
* Try to allocate chunks of 4K at most for walloc(), or 8 objects at least.
* Created new GTKG-specific GGEP extension "GTKGV1" to propagate version
information and servent startup time in query hits.
* Added inet_init() to ensure we have the no-connection timer set if we
startup in non-firewalled mode.
* Will now emit "GTKGV1" extensions in query hits when replying to a GTKG
query, and display version information in search pane.
* Exported version_str() for version string formatting.
* Be sure to not call inet_firewalled() on first listening port change,
i.e. when we read back the configuration file, or the persisted
"is_firewalled" property will be ignored!
- (2003.01.08 - RAM)
* Forgot to check for alternate locations on 503 replies.
* Also compare SHA1 of requested files when checking for upload duplicates.

- (2003.01.04 - RAM)
* Had forgotten that we must "goto next" instead of "continue" in
the URL parsing loop from dmesh_collect_locations().
* Added argument to download_remove_file(), so that we can reset the fileinfo
of manually removed files, in order to not discard the entry at the
next startup.
* Fixed hops-flow handling in mq_service(): was generating bad iovec entries
for dropped messages!
* Don't need to send the "Connect Back" message as a control message.
* Seeing a vendor-specific message sets the NODE_A_CAN_VENDOR attribute as
if we had seen a Vendor-Message header.
* Drop ping/pongs/pushes that are smaller than their normal size.
* Added support for initial advertising of supported vendor messages.
* Count unhandled vendor-specific messages as being of an "unknown type".
* Was wrongly putting a trailing 's' to the Vendor-Message header.
- (2003.01.03 - RAM)
* Added support for vendor-specific messages.
* Ban ancient-enough versions of GTKG.
* Ignore leading/trailing quotes in "quoted" URLs from Alternate-Location.
* Keep track of IDs from unknown GGEP extensions we see.
* New miscellaneous routing hex_escape().
* Now supports the "Hops Flow" vendor-specific message (BEAR/4v1).
* New version_is_too_old() routine.
* Exported vendor_code_cmp() and added vendor_code_str().
* Make sure there is a private extension in the query hit before calling
ext_parse() on it.
* New Gnutella node flag 'h' or 'f' to indicate hops-flow or flow-control
on the receiving side (hops flow message sent to remote node so that it
limits the traffic sent to us).
* Added pre-condition to gmsg_check_ggep().
* Sockets now allocated via walloc0() instead of g_malloc0().
* Implemented the "Connect Back" vendor-specific message (BEAR/7v1).
- (2003.01.03 - cbiere)
* [Gtk2] Added multichoice for toolbar style
* [Gtk2] Added property for collapsed/expanded status of nodes in tree menu
* [Gtk2] Added multichoice for toolbar style
* [Gtk2] Several syncs with Gtk1 version
* [Gtk2] Moved "Freeze queue" button from toolbar to download pane

* Added GtkHBox around child where GtkViewports are used.
* Added new props to gui ("dl_queue_count", "dl_running_count",
"dl_byte_count" and "ul_byte_count")
* Fixed percentage toggle for "drop reasons" table in gnet stats
- (2003.01.02 - RAM)
* New properties: "dl_queue_count", "dl_running_count", "dl_byte_count"
and "ul_byte_count".
* Maintains two new property counters: amount of running downloads and amount
of queued downloads.
* Now counts total useful bytes uploaded.
* Now counts total useful bytes downloaded.
* Added error reporting for failed download mesh URL parsing.
* Added error reporting for failed HTTP URL parsing.
* Added Shinobu (SHNB) vendor code.
* Fixed "was a duplicate" computation, which falsely reported duplicates
with oneself!
* Was not filling the ultra cache correctly upon startup.
- (2003.01.02 - cbiere)
* Bugfix: Wrote into stats array out of bounds (gnet_stats.c)
- (2003.01.02 - Richard)
* Added UP host catcher to gnet panel
* Redesigned a few config panels
* Added "ko" to contibutors
* Added information about the OS to the about dialog
* Added hidden RCSID label to the gui (about dialog)
- (2003.01.01 - RAM)
* Removed the G_INLINE_FUNC attribute in node_add_tx() and friends, as
it no longer links properly.
* Template props.tpl was not defining the default value correctly for
the new "multichoice" type, resulting in badly initialized properties
whereby the default of the previous property was used.
* Replaced an "inline" directive in nodes.h with G_INLINE_FUNC.
* Added a wrapper on top of the qrp_patch_compress() user-defined callback to
cleanly remove the task from the list where we put it at creation time.
* Added tracing of extensions for big pings/pongs/pushes.
* Validate all the /uri-res/N2R?urn:sha1 alternate locations we might get.
* Whenever we can do a successful /uri-res/N2R? request, force the download
to always request that URL from the server to avoid problems in case the
library is reshuffled remotely (for non-GTKG servents). This also forces
the /uri-res/N2R? URL into the download mesh.
* Fixed logic bug in upload code for checking that followup requests still
refer to the same source.
* Check for duplicate download in new download_convert_to_urires().
* In leaf node mode, ignore the "hops_random_factor" property.
- (2003.01.01 - cbiere)
* Fixed identifiers with leading underscores
* Removed usage of __FUNCTION__ as it's a gcc-only feature
* [Gtk2] Hide label with RCSID
- (2002.12.31 - RAM)
* Added static RCS Id to all the C files.
* Now accepts and forwards big pings/pongs/pushes to nodes that will
advertize "GGEP: 0.5" (at least) in their handshakes. Other nodes
will get a stripped down message without the GGEP extensions.
* Do not send a RESET before subsequent PATCH messages if we already
sent a routing table to our ultrapeer, unless the new table has a

GINT_TO_POINTER() et al.
- (2002.12.02 - RAM)
* ban.c: forgot missing trailing space after the "Gnucleus" name.
- (2002.11.30 - RAM)
* Was passing 'len' as a macro argument, which was then copying this into
a local variable called 'len' => was getting garbage into that value.

# v 0.91.1 2002.11.22 [stable]
Highlight of changes (user-visible):
- Will now verify the SHA1 of downloaded files in the background.
- New configuration parameter for the directory where "bad files" not
matching their advertised SHA1 should be put (don't forget to configure
it, as it defaults to /tmp).
- Files are now copied in the background, so it is possible to setup the
various "download" directories on different filesystems.
- Node connection time and remote node's uptime (if available) are now shown.
- It is now possible to paste a "magnet:" URI in the search to launch a
SHA1 search.
- The "connection indicator" at the bottom left is now a toggle. Depressing
it will terminate any Gnet connection but will continue to serve uploads and
process downloads.
- The active download status now shows how many sources are available and
how many are currently active (i.e. downloading). It will also show the
estimated remaining time for the whole file, as well as the global reception
rate for the file, accounting for all currently active sources.
- Fixed bug that prevented proper downloading from recent BearShare (4.1.x or
better) and Shareaza (1.6.0.x or better) nodes when the SHA1 of the file
is known.
- Will now protect against "PUSH floods" by banning the relevant IPs.
- At startup, scan the download "tmp" dir for orphan files and reintegrate
them into the fileinfo database, moving completed files to the relevant
directory (depending on whether its SHA1 checked OK).
- Minor bug fixing: improper countdown for push timeout when falling back,
fixed corner-case processing that could lead to crashes or incorrect
behaviour, accidental localization on X-Live-Since headers, freezing of the
GUI when clearing many uploads, obscure portability fixes.
- (2002.11.20 RAM)
* New `version_number' variable is now built to hold the version number string.
* Do not show them new development versions if they don't run one.
* Display message every 10 minutes in the status bar if they run an ancient
version, more than one year old.
* Added copyright statements for David Walker.
* Do strftime("%z") formatting ourselves, since %z is a GNU extension.
- (2002.11.22 RAM)
* Moved sendfile() checks where they belong, i.e. in bio_sendfile(), with
additional paranoid checks.
* Unplugged QRT computation for 0.91.1.
* Fixed maximum random value computation when random() is being used on
other machines than Linux [With the help from Uros Bizjak].
- (2002.11.17 Richard)
* [Gtk2] Fix crash when removing a search and switching to a new search.
[Patch from Christian Biere].
- (2002.11.17 RAM)
* Added support for urn:bitprint:, although only its SHA1 part is processed.
* Always verify that we have 32 chars before calling base32_decode_into()
to decode an urn:sha1.
* Now understands "magnet:" URIs in search [Patch from David Belius].
* Will now use GGEP "H" in query hits when replying to a query from GTKG 0.91
or better, since we're sure the querying host will understand it.
* Clearing of completed uploads now done "incrementally" to avoid freezing
the GUI when there is a lot to clear [Patch from Christian Biere].
- (2002.11.15 RAM)
* Servers understanding /uri-res/N2R? may not send X-Gnutella-Content-URN.
* No need to unlink the file in download_move_done().
- (2002.11.14 Richard)
* Don't try to connect to new hosts in offline mode
* Display "loading..." in host catcher while reading the file
* Change plug icon if manually switching to offline mode
- (2002.11.12 RAM)
* New file moving code was not properly stripping trailing fileinfo.
- (2002.11.12 Richard)
* [Gtk2] Add new widgets from Gtk1 frontend
* [Gtk2] Filled in contributors to about box
* [Gtk2] Greatly improved search monitor performance
- (2002.11.11 Richard)
* Added entry for PROP_BAD_FILE_PATH to download config
* Added icons to reflect state of PROP_FILE_MOVING
* Added uptime and connected time columns to nodes table
- (2002.11.11 RAM)
* New http://gwebcache.bearshare.net/gcache.php replaces the old zero-g.net
hardwired bootstrapping web cache, which was shutdown due to traffic.
* No longer uses strftime() to format date string for X-Live-Since, since
it insists on using the user's locale.
* Added asynchronous moving of downloaded files.
* Renamed node_connected() as node_is_connected().
* The verify_queue() routine no longer knows about download states.
* Don't reject PUSH comming from a private IP if we're connected to it
(this is mainly for testing purposes but will not hurt).
* Changed property descriptions of "download paths" to remove any constraint
on them being on the same filesystem.
* Also parse the Uptime header instead of X-Live-Since (Gnucleus nodes).
* Show the server's uptime, even if we're not connected to the node.
- (2002.11.09 RAM)
* The BSD sendfile() requires that first two arguments be swapped (wrt linux).
* Now computes and displays the overall swarming downloading rate and the
time that remains to get the complete files. Also shows how many sources
we're currently using out of the ones we know.
* New unique_filemame() routine.
* New "file_moving" property to indicate that we move files in the background.
* Default for dynamic upload slot allocation is now FALSE.
* Added logic to make the new "online mode" toggle actually work.
* Shortened retry delay to 2 seconds when server cannot understand /uri-res.
(unless server explicitly set a Retry-After, in which case we honour it).
* When we abort a download due to a header reception timeout, we might
not have got the full status line.
* Now computes the "startup date" for the nodes to which we connect, parsing
the X-Live-Since header.
* Ensure we have "LC_TIME=C" in our environment. Some X-Live-Since headers
are still incorrectly localized by strftime().
- (2002.11.07 RAM)
* Fixed memory leak in search_stats_notify_word() [From Christian Biere].
* Added new property "bad_file_path" to indicate where files which do not
match their advertised SHA1 should be moved.
* Was wrongly testing for queued download instead of running one in
queue_suspend_downloads_with_file(), which could mess up with lifecount.
* Will now retry downloads for which the SHA1 did not match.
* When unlinking a file, display its SHA1 (if any) and the done/size info
to stderr.
* The BSD sendfile() has different signature and semantics. Emulate the
Linux behaviour on those systems.
- (2002.11.07 Richard)
* [Gtk2] Added new icons from Gtk1 and"prefer compressed" switch.
* [Gtk2] Columns in gnet panel automatically grow in width again
* [Gtk2] Fixed bug showing status information in version row on gnet panel.
* Fixed sizeof issue (memory corruption?). Thanks to Christian Biere for
pointing it out.
- (2002.11.06 RAM)
* More tweakings with fileinfos: will now physically remove files that are
SHA1 or name/size ignored (if not completed already).
* Forgot a few calls to file_info_clear_download() which releases the
association between a download entry and a chunk in the file.
- (2002.11.05 RAM)
* Don't show SHA1 computation rate if we did not hash anything (e.g. after
a recovery crash where we jump to the "SHA1 verified state" directly).
* Revisited fileinfo handling: try to not discard them when a download
stops, unless it was an explicit removal from the user or we are told to
ignore its SHA1, for instance.
* Fixed possible discrepancy between the download's SHA1 and the fileinfo's.
In particular, we could associate a download with a known SHA1 with a
fileinfo not bearing a SHA1 at all.
- (2002.11.04 RAM)
* Restored broken support for sendfile(): configure was no longer setting
the proper variables, leading to sendfile() being ruled out everywhere
even when present.
* Inclusion of sys/sendfile.h now protected by HAVE_SYS_SENDFILE_H.
* Prevent concurrent downloads from being stuck in the "Waiting for SHA1..."
when another one finishes: requeue them as they are suspended.
* Will now say "SHA1 figure OK" instead of "SHA1 check OK" when we correctly
computed the SHA1 but none was originally known for the file.
* Skip non-plain files when scanning the "tmp" directory for orphan files
[From Uros Bizjak].
* Persist settings of the "prefer compressed connections" toggle button
[From Christian Biere].
* Will now protect against "PUSH floods" by banning the relevant IPs.
* Avoid doing some work if we are going to use the sendfile() system call.
* Added temporary sanity checking around sendfile(), just in case it does
not behave as advertised.
* Freeze GUI list when clearing completed uploads [From Christian Biere].
- (2002.11.03 RAM)
* Refuse to start a "suspended" download, requeuing it as "Suspended".
* Moved settings of the DL_F_SUSPENDED after download is allocated
(thanks to Paul Cassella for spotting this).
* Log vendor string when HTTP/1.1 server gives us more bytes than requested.
* When we have to trim data, we can't use keep-alive connections: remember
bad servers so we don't request upper-bounded ranges from them again.
* When logging to "done.sha1", use the output filename as name, not the
server name, which could be an obscure urn:sha1: string.
* When resuming after crash, forgot to handle the case where a completed
file could be listed many times in the queue.
* Was showing bytes/s instead of kbytes/s in the final SHA1 computing
rate display.
* Added new is_faked_download() routine.
- (2002.11.03 Richard)
* Added default extensions: doc, nes, smc, smd, rom
* Changed default sidebar width to 140
* Changed default filter-tree size in filter dialog to 140
* Changed default 'Jump to download' to FALSE
* Fixed tooltips of the firewalled/non-firewalled icons
- (2002.11.02 RAM)
* Added asychronous SHA1 verification routines.
* Extended the background task model to also support "daemon" tasks, which
are tasks that sleep in the background and are woken up when work is to
be performed.
* Plugged in SHA1 verification when a download is complete.
* Display SHA1 computation status in the download window.
* At startup, scan the download "tmp" dir for orphan files and reintegrate
them into the fileinfo database, moving complete files to "done".
* Only send urlfile requests to web caches once every 8 hours.
* Split ignore_add() into ignore_add_sha1() and ignore_add_filesize().
* Old code that could move back a file from the "done" directory to the "tmp"
directory was removed. We now have stricter file management with SHA1.
* Fixed routing_log() which was not logging anything.
* Removed spurious checks in get_file_to_upload_from_index(), replacing
them with assertions.
- (2002.10.30 RAM)
* Raised logging level for some innermost traces in bg.c.
* Moved check for "no GUID to use PUSH" to download_push() to avoid seeing
retry countdowns when a connection cannot be made.
This updates yesterday's fix.
* Integrated batch of portability and cleanup fixes from Christian Biere.
* Don't call search_close() too early [Fix from Juli Mallett].
* Avoid dereferencing a NULL `current_search' variable [From Juli Mallett].
* When falling back to push, reset the time for accurate push timeout.
- (2002.10.29 RAM)
* New background task layer.
* Added X-Host: support to specify non-firewalled server's IP address to
pushed uploads. A pushed download seeing X-Host in the reply knows that
the server is not firewalled and that a direct connection can be made.
* Added provision for storing computed SHA1 in fileinfo trailer.
* Plugged background task timer.
* Converted existing SHA1 and QRP computation code to new background tasks.
* Integrated random() support from Christian Biere.

- (2002.10.24 RAM)
* Opening version 0.92u.
* Stricter banning policy: ban after 5 reqs/minute instead of 10.
* Fixed typo "interaface" -> "interface" in some includes.
* Show download's disk filename when all we have from server is an URN.
* Don't show "503 rebuilding library" when in fact we don't share anything.
* New walloc0() routine.
* Now allow again setting "min Gnet connections" to 0.
# v 0.91 2002.10.19 [stable]
Highlight of changes (user-visible):
- Now uses HTTP/1.1, which implies support for persistent connections.
- gtk-gnutella will now monitor whether we're connected to Internet and
slow down its connection requests when it detects the connection was broken
(after a delay of ~3 minutes at most).
- Download swarming is now supported: gtk-gnutella will download different
portions of the same file from many hosts, as long as alternate sources
are available.
- The download mesh (alternate source collection during downloads) is now
used to fill the download queue with more sources.
- Alternate locations can also be passively collected from query hits.
You can enable this in the swarming section on the download config pane.
- Download scheduling was entiretly redesigned to avoid hammering busy hosts
and scale to 5000+ entries in the queue without slowing down the whole.
- Is now smart about the "push" flag and will try to ignore it if possible,
in case the remote host wrongly set the flag but is not firewalled.
- gtk-gnutella now remembers the files it downloaded and will ignore further
requests to download the same file. It will visually mark those files, as
well as the ones it already shares, by showing them in lighter color in the
search results.
- It is possible to supply to gtk-gnutella your own ignore lists by SHA1 and
by name/size but the feature is under-documented.
- Added an "expert mode". Only when this is enabled will gtk-gnutella show
the users some of the most complex settings.
- New Gnutella statistics pane, showing the packets we sent and received,
how many we generated, and the reasons why we drop packets, by packet type.
- Now understands UTF-8 queries, but does not generate them.
- Fixed important bugs whereby all earlier versions of gtk-gnutella were
unintentionally corrupting the Gnutella traffic!
- Moved away from the public hostcaches and now uses the Gnutella Web Cache.
- Will now show all upload attempts, not only the ones that are transferring.
If the connection is aborted, the reason is also shown.
- New search stats types: queries by router, whole query.
. "Queries by router" shows how many queries have been recieved
from any node gtk-gnutella was directly connected to.
. "Whole query" shows stats based on the complete query string
instead of individual query words.
- New visual indications via icons in the status bar: whether gtk-gnutella
is rebuilding the library, computing SHA1 of shared files in the background,
and whether we are connected to Internet or not.
KNOWN BUGS/PROBLEMS:
- When changing the directory for incomplete/complete files, all
partially downloaded files recorded in ~/.gtk-gnutella/fileinfo
will still be downloaded to the old directory. You need to manually
change the paths in above file using search/replace and your
favourite text editor.
- Sorting order of tables is not perserved across sessions.
- Marking/highlighting of results/downloads/uploads heavily depends
on your GTK theme. Especially most themes do not set fg[ACTIVE] and
fg[NORMAL] to different values.
- There is currently no way to un-ignore a file via the gui. You
can however edit the done.sha1 and done.namesize files in your
~/.gtk-gnutella directory manually. Unignoring via gui is planned
for the next release.
- (2002.10.19 RAM)
* Changed error code for non-compressed connections from 401 to 403.
* Cleaned up manual page: removed obsolete information about config options.
* Cleaned up Gnet & GUI properties.
- (2002.10.18 RAM)
* Small cleaning of whitelist/local (patch #623100).
* Switched from 409 to 503 when "already downloading that file" so that
user can retry later on: this is not a fatal error.
* Added pre-condition in download_request().
* Revised the descriptions of gnutella properties, and changed a few
limit values that were wrong (TTL, max TTL, etc...).
* Make sure we do not fill a query hit with more than 255 results.
* Only trim TTL larger than our max_ttl for broadcasted packets.
- (2002.10.17 RAM)
* Reset "Clear Completed" correctly in upload pane when auto-clear is on.
* Disabled failing assert in file_info_find_hole(), replaced by a warning
for now, pending further investigation after the release.
* Fixed Gnet compression rejection messages.
* Also send out X-Try when rejecting connections based on lack of compression.
- (2002.10.17 Richard)
* Fixed several bugs in filter_cb.c when copying/pasting a rule.
* Fixed bug: hostcatcher does not update properly in gui if no hosts
file was found.
* Added "prefer compressed connections" option to gnet config pane.
(expert mode) [thanks to Markus "guruz" Goetz]
* Replaced GtkSpinButtons with GtkEntry in the size-rule part of the
filter dialog. Should give the full range of sized up to 2GB.
- (2002.10.15 RAM)
* Added GGEP parsing and generation code.
* Added support for COBS (required by GGEP).
* Fixed "abort from host" routine.
* Fixed improper lifecount in downloads, when resuming leads to a Duplicate.
* Added assertions in gmsg_dump() and gmsg_split_dump().
* Forgot to cancel the "urlfile" retry event during shutdown.
* dump_hex() can now handle zero-sized dumps.
* Will now recognize GGEP "H" extensions in query hits.
* Protected some GUI warnings with "if (gui_debug)" tests.
* Now knows how to generate GGEP "H" extensions in query hits, code disabled.
- (2002.10.14 RAM)
* Fixed bug when following HTTP redirection during downloads.
* Lowercase the Content-Range header value before parsing.
* Don't send them the download mesh entries if they abort on "Stopped (EOF)",
as they might choke on the HTTP continuation.
* Converted to new gnet_prop_get/set_type_val() macros.
* Generated property routines now have the opening "(" after the name.
* Merge adjacent "unknown" extensions in vector.
* Added new REMAP_ZALLOC compile flag to remap zalloc() and walloc() to
malloc(), indepently of the USE_DMALLOC flag.
* Added new properties: "library_rebuilding" and "sha1_rebuilding".
* Forgot to reclaim current web cache URL atom during final cleanup.
* Be nice to pushed uploads and don't impose them to follow a 301 if they
don't request the proper file and give a SHA1 in the HTTP header.
- (2002.10.14 Richard)
* Added icons to display state of background processes (building lib/sha1)
to statusbar.
- (2002.10.13 RAM)
* Made socket_destroy() a private routine of sockets.c, which now takes
a reason string that can be propagated back to the socket's resource
for better error logging.
* Fixed stupid error in vendors.c: was comparing aginst '0', instead of '\0'.
* Give more precise feedback for failed pushed uploads.
* Forgot to initialize flags in HTTP async requests.
* Fixed HTTP redirection bug: had put a wrong assertion.
* Applied Solaris portability patch [From Uros Bizjak] (patch #579522).
* Always parse query hits bearing 4 bytes of open data, whatever the vendor.
* Fixed some function formatting, according to point 4.5 of STYLE guide.
* When creating a new search, immediately send message to the search queue
as soon as the search is unfrozen (fixes bug #617206).
* Turn fuzzy name matching off by default, since it is potentially unsafe.
- (2002.10.12 Richard)
* Option to visually mark ignored files in the search results.
* Update local address displays when listen port is changes (closes 622020).
* Optionally accept the first chunk of a file from a source that does not
supply a urn to match against. This dramatically reduces the number of
"No URN on server". This only helps in cases where you never get a file
because the only source you have does not provide a urn.
* Add a viewport to all config panes so they can be scrolled if the window
too small to show them completely.
* In gwcache.c: when stopping because we get 50+ lines, use
http_async_close() and not http_async_cancel() as it is not an error,
so we don't want the error callback to be called.
* In http.c: when making a subrequest, disable timeouting of the now idle
parent request.
- (2002.10.12 RAM)
* Fixed get_file_to_upload_from_index() to avoid writing to freed memory.
* Added pre-condition in io_read_data().
* Added asynchronous disposal of HTTP async requests to avoid writing
into freed memory upon user callback returns.
* Just because a hostname starts with a digit does not mean the host was
given as an IP address (fixes bug 617315).
* Display pushed uploads in light gray ("insensitive"), just as we do for
pushed downloads.
* Was not properly reporting errors when given bad URN in /uri-res.
* Also report 503 if given a /uri-res and we are still rebuilding, in case
we do not find the file for the URN: we might not have parsed it in the
library if it is large.
* When downloading, ignore SHA1 of files we already share in our library
(fixes bug #618722).
* Made `current_url' an atom in gwcache.c to avoid race conditions with
the entry being superseded.
* Delay next urlfile webcache request when the previous failed.
- (2002.10.05 RAM)
* Never send pushes if we think we're firewalled.
* Made "misc.h" include "config.h" for compiles on FreeBSD.
* Further changed the upload request checking order for better GUI reporting.
- (2002.09.28 RAM)
* Added ATOM vendor code.
* Check HTTP upload request after we extracted the vendor information.
* Drop "QTRAX2_CONNECTION" queries.
* When we're firewalled, answer pings at regular intervals, to help us
determine whether we're really firewalled. Even if we have no slot.
* Moved "TTL exceeded" reason at the top, with related reasons.
* Fixed download fileinfo reparenting bug.
- (2002.09.25 RAM)
* Added ACQX and EVIL vendor codes.
* Shuffled code around in upload_request() to gather as much information from
the request as early as possible for GUI display purposes in case of error.
* Now recognizes UTF-8 queries starting with Byte Order Mark tag.
* Drop and count malformed UTF-8 queries we encounter.
* Removed unused count_running_downloads_with_sha1().
* Added my own cache to the bootstrap list.
* Fixed the _shutdown() routine in property template to avoid freeing NULL.
* Vendor ACQX can include XML payload in query hits.
- (2002.09.24 - Richard)
* Cleant up search_xml.c a little
* Fixed another memory leak in search_xml.c
* Partially fixed: Uploads and downloads won't abort (#612374)
Should work for uploads, "abort by SHA1" and "abort by name". The
"abort by host" was optimized by Raphael and I dont see the bug right now.
- (2002.09.24 RAM)
* Added the EXT_NONE extension to hold separator overhead.
* Don't warn at exit time on fileinfo entries with refcount=0.
* At debug level 5+, can now log the packets we emit, and the non-broadcasted
messages we relay..
* Suppressed MSG_DROP_MULTIPLE_SHA1, added MSG_DROP_QUERY_OVERHEAD.
* Renamed MSG_DROP_MISFORMED_SHA1_QUERY as MSG_DROP_MALFORMED_SHA1_QUERY.
* Documented web cache usage policy.
* Added cache seeding when the caches we inspect have few entries.
* Fixed memory leak in nodes.c.
* No longer send the trailing "urn:\0" in queries.
* When issuing SHA1 queries, was not copying the trailing NUL.
* Will now drop queries with too many (unneeded) separators in extension.
* Now supports queries with multiple SHA1.
* Split our query hit packets in chunks of ~2KB for better flow control.
* Fixed missing counter decrements on completed uploads.
- (2002.09.23 RAM)
* When replacing URLs in the web cache, delete from the known URL table
before re-inserting, for the rare cases where we're inserting the same
URL at the same slot.
* Removed spurious block that crept in inside gwc_store().
- (2002.09.23 - Richard)
* fixed memory leak in:
- search_xml.x (config_comment)
- hosts.c (parse_netmasks)
- settings.c (move_file_path_changed)
- settings.c (save_file_path_changed)
(thanks Rhamphoryncus for spotting)
* Gui/core separation for uploads
* Better monitoring of the gtk-gnutella internal server activity including
monitoring of failed upload attempts and connections that are being kept
open.
* Fixed: upload status bar fails to decrement (closes #609479)
* Should no longer give floating point exception on Alpha (closes #609253)
Always use gtk_progress_bar_set_fraction and check that we don't do a
div-by-zero when calculating the fraction.
* Started to move gui initialization code from main_gui.c to the respective
initialization functions of the different gui modules. That gives less
problems with migrating to Gtk2 specific frontend modules.
* Revisited gui/core separation code for gNet connections. Don't transfer
the whole node information on each update. Don't alloc/free memory on
each status update.
* Use GtkTreeView instead of a GtkCList to list the gNet connections.
Breaks popup menu and removal of nodes in the experimental Gtk2 version.
* Destroy sorting arrow in search results panel when a search is closed.
(thanks to Bjorge Dijkstra for spotting and providing a fix).
* Moved PROP_AUTOCLEAR_UPLOADS from gnet_props.ag to gui_props.ag
* Give more warnings if a widget is not found in settings_gui.c
* Added "searches by router" to search stats.
* Remove sidebar viewport again (Gtk1)
- (2002.09.22 RAM)
* Forgot to initialize a field when starting an aync HTTP request.
* QRP hash code no longer uses tolower() and only translates [A-Z] to [a-z].
* Adapted zalloc/walloc code to be usable under dmalloc.
* Added support for transparent redirection in async HTTP requests.
* Unplugged all support for the now-dead public hostcaches.
* Fixed a few "free(NULL)" calls spotted by dmalloc.
* Save URLs in gwcache starting with the oldest ones.
* Rotate the web cache used after a few updates.
* Downloads were still using obsolete index==0 convention to indicate the
/uri-res URLs. It is now index==URN_INDEX that must be used.
* Fixed embarrassing bug: we were bluntly changing the query text on the
fly by calling st_search() on the original query text!
* Fixed memory leak in fileinfo.c.
- (2002.09.21 RAM)
* Removed hostcache "gnutella-again.hostscache.com": no longer resolves.
* Added http_async_close() to cleanly request connection close.
* Added url_escape_query() to escape query string parameters in URLs.
* Periodically save Gnutella web cache ring if dirty.
* Finalized web cache support to publish our IP and propagate ring.
- (2002.09.20 RAM)
* Forgot to update the name hash-table when changing fileinfo.
* Must always seek before writing to a downloaded file, even when swarming
is OFF, since we always update the trailer, hence changing the write
pointer.
* Don't lseek to the trailer if we're not going to write it anyway.
* Finalized asynchronous HTTP request support.
* First implementation of Gnutella web cache support. No update yet.
* Added new core property "incoming_connecting_timeout".
* Improved str_chomp() to also strip trailing "\r\n" or plain "\r".
- (2002.09.19 RAM)
* Added COCO to the vendor list.
* Check for sendfile() or write() returning 0 in case the underlying file
disappears on a non-Unix filesystem such as FAT32. This avoid endless
loops (fixes bug 611537).
* Check for the HTTP protocol tag before URL-unescaping the request,
which could shift the string backward in the buffer.
* Vendor tags are now defined in "vendors.h".
* Fixed wrong drop message.
* More untested code on asynchronous HTTP requests.
- (2002.09.18 RAM)
* Factorized asynchronous I/O header parsing code.
* More embryon of code for asynchronous HTTP requests.
* Automatically compact query text in messages we send.
* Now only compacts white-spaces in query text, and only for messages
we are going to relay.
- (2002.09.16 RAM)
* Fixed Alternate-Location parsing to avoid mistaking an URL for a date.
* Should now correctly guess whether a "," in an URL is a separator of
two URLs or is part of the current URL.
* Special index to indicate URN is now 0xffffffff instead of 0.
* IP/port parsing of URLs is now done in http.c.
* Embryon of code for asynchronous HTTP requests.
* Fixed download problem with swarming deactivated.
* Socket type/direction constant refactoring.
* Capitalized first letter of all Gnet stats.
* Removed MSG_DROP_RESULT_DOUBLE_NUL, which was wrong.
* Changed MSG_DROP_QUERY_TOO_LONG into MSG_DROP_QUERY_NO_NUL.
* Added MSG_DROP_PONG_UNUSABLE.
* Query compaction is now enabled by default.
* Now counts unusable pongs that we drop.
* No longer alter open-data of query hits inplace for LimeWire/Swapper hits!
* Will now detect query hit trailer with GGEP extensions.
* Parse trailer extensions for validation only (currently).
* Count queries with no trailing NUL as such.
- (2002.09.15 Richard)
* (Hopefully) fixed flickering in gui by jailing label_items_found and
label_search_stats_count into GtkViewports (Gtk1 & Gtk2)
* Added "(Globally) drop results from host" to search popup
* Added "New search from selected" action from search results
pane. Creates a new search based on the filename found and
adds a filter to it based on the sha1 hash if it has one or the
exact filename if it hasn't.
(patch by Andrew Meredith <andrew@anvil.org>)
* Fixed up build files following suggestions from Andrew
* Bumped version in configure.in
* Fixed warnings in gtk-missing.c when compiling with Gtk2
- (2002.09.12 RAM)
* Was mistakenly going through routing_log() formatting even if the debug
level did not justify it.
* Query compacting is now UTF-8 safe.
* No longer transform UTF-8 queries into ISO-8859 inplace: we now let UTF-8
queries go through as-is.
* utf8_to_iso8859() forgot to decrement length of original string.
- (2002.09.12 Richard)
* Renamed share_gui2.c to monitor_gui2.c
* Added checkbutton to config-UI panel to toggle expert mode
* Fixed freeze-bug when adding filter rules via search popup
* Optional compaction of queries (default off). This cleans up
the search stats and saves a little bandwidth but in turn costs
a little cpu.
* Enabled Gtk2 frontend again (experimental)
* Fixed typo "No item found" => "No items found"
* Reordered result processing in share.c: first check wether results
should be dropped, then notify listeners (search monitor/stats),
then check wether to perform a local search.
- (2002.09.11 RAM)
* Make sure we leave enough room in the reply HTTP header for final "\r\n".
* Re-organized download_request(), with better detection and handling
of header timeouts.
- (2002.09.10 Richard)
* Expanded gnet statistics
* Added percentage display for gnet statistics
* Moved "(globally) drop..." do submenus. More to come
* Renamed "local" to "generated" in the gnet statistics
* "Can't remove node" bug should be fixed now
* Fixed serious bug in idtable: last_id was not initialized!
* Removed wrong assertion: node handle may be 0
* Fixed bug: when removing multiple nodes, only the first is
removed
* Expanded search stats. Can choose between "word" and "query" stats.
* Renamed search_stats.[ch] to search_stats_gui.[ch]
* Integreted search stats in gui_update_global.
- (2002.09.09 RAM)
* Fixed reference count problem when resetting fileinfo.
* Made socket_connected() private.
* Count sent message size from queue accurately.
* Cleanup of statistics, separating reception: header and payload counted
separately.
* When reading back fileinfo cache, guard against duplicate ALIA entries.
* Split sent statistics into local and relayed.
* Requeue downloads with a SHA1 in the fileinfo but for which the server
gives no URN: it will wait for an overlap to resume, provided the user
has at least configured 64 bytes of overlap (fixes bug #606373).
- (2002.09.09 Richard)
* Finally added the "expert mode". This means you'll not see lots of
settings in the config panes next time you start. If you want to
enable the expert mode, edit your "config_gui" file in ~/.gtk-gnutella
manually and set "expert mode" to TRUE.
* Added drop statistics for every message type and accumulated traffic
statistics for every message type.
* Reduced number of drop reasons and use same reason for different
message types.
* Don't bother trying to find a hit if we don't share any file.
* Added stats for local query hits
* Again changed gNet pane update behaviour (once per second)
- (2002.09.08 Richard)
* Update nodes in gNet panel more often.
* Added gnet statistics
* Added "User interface" settings to config pane.
* Made (most) tooltips optional.
* Show confirmation dialog when leaving gtk-gnutella (optional)
* Moved code from callbacks.[ch] to downloads_cb.[ch] and uploads_cb.[ch]
* Moved code from gui.[ch] to main_gui.[ch]
* Moved code from gui.[ch] to downloads_gui.[ch] and uploads_gui.[ch]
* Moved code from main.c to main_gui.[ch]
* Moved declarations of functions needed by gui from downloads.h to
gnet.h
* Temporarily relocated a struct declaration from upload_stats to gnet.h
* Changed code to update sidebar stats
* Added feature summary to output of configure script
* Mark files downloaded by "Watch searches for alternate sources" as
"queued" in search results (same marking as when you manually download
them)
* Don't generate duplicate filter rules when creating rules from
a number of selected search results.
* Updated clist_collect_data to be more usable
* Moved code from upload_stats.[ch] to upload_stats_gui.[ch]
* Use properties to set scan extensions
- (2002.09.08 RAM)
* Fixed problem when requeuing a stopped download from the GUI.
* Internal invalidation of the "fileinfo" was leaving a NULL pointer and
this is confusing: always reget a proper fileinfo when invalidating.
* Resize fileinfo when we get a larger file with same SHA1.
* When about to move to "disconnected from the Internet" state, look whether
there was incoming traffic received recently.
* Don't assert that size_atom exists on fi_free(), it could be missing.
* Fixed Richard's sent counter stats.
- (2002.09.07 RAM)
* Added "int" atoms.
* Refactored swarming meta-information management to avoid conflicts between
different files, and really put identical sources to the same output file.
* Make sure we don't display negative retry times for downloads.
- (2002.09.06 RAM)
* Factored out handling of (name, size) tuples.
* Was wrongly forwarding query hits with bad SHA1s when debugging disabled.
* Made guid_random_fill() a public routine.
* Was badly computing position in queue when it holds more than 1024 entries.
- (2002.09.02 RAM)
* Fixed duplicate server free bug (fixes bug #603365).
- (2002.09.01 RAM)
* Made local_ip persistent, in case it takes time to determine dynamically.
* Fixed some English typos in the gnet properties ("then" -> "than").
* Was missing a trailing "\n" in whitelist.c debugging statement.
* Added workaround for sscanf() parsing bug: always end parsing with a
scanned parameter.
* If remote HTTP/1.1 does not honour keep-alive on the connection as promised,
mark it as not supporting keep-alives.
* Also defer reclaiming of the server structure when freeing a download.
- (2002.09.01 Richard)
* Search panel redesign
* Minor cosmetic fixes
* Adjust idtable to RAM's suggestions
* Make search reissue timeout setting in GUI behave properly again
- (2002.08.31 RAM)
* Changed the way GUID are generated for messages and servents.
- (2002.08.29 RAM)
* Actual freeing of download structures is now deferred to avoid race
conditions with list traversals.
* Plugged download ignore lists. The lists are kept in ~/.gtk-gnutella.
Files ignore.sha1 and ignore.namesize are user-supplied, files
done.sha1 and done.namesize are generated by gtk-gnutella. The format
of the *.sha1 file is that of "sha1sum", the format of *.namesize
is that of "wc -c".
* Removed wrong assert in file_info_recreate() (fixes bug #601626).
* Make sure upload slot is reserved between two consecutive queries on
a persistent HTTP/1.1 connection.
* Fixed minor style issues in vendors.h and whitelist.c.
* Fixed improper display when new version is encountered.
* Fixed file descriptor leak in ignore.c.
- (2002.08.29 Richard)

new id_table instead.
- (2002.08.28 Richard)
* Changed justification of columns in search stats
* Moved search stats to gui side. Use the same callback as the
search monitor to get information from backend.
* Fix search stats so that a change in the update interval does immediatly
take effect.
* Expanded search_request_listener signature to contain a query type and
a query string. This way the gui can decide how to handle SHA1 queries.
(Search monitor displays them, search stats drop them)
* Fixed up search monitor to handle SHA1 queries on the gui side.
* Moved all search stats properties to gui.
* Moved more stuff out of callbacks.[ch]
* Moved build_url_from_download from misc.c to downloads.c
* Moved gtk_gnutella_exit prototype to common.h
* Cleant up gui.[ch]. Moved code to downloads_gui.[ch] and search_gui.[ch]
* Made column headers insensitive for tables that can not be sorted.
* Moved node_ip and message_dump from misc.c to nodes.c
* Added upload_kill() to uploads.[ch]
* More include cleanups for gui<->core separation
* Export host_clear_cache in gnet.h
- (2002.08.27 - RAM)
* When swarming: if we do not upper-bound the chunk, display a "+" after the
displayed chunk size in the download Range column.
* Banned URLs with an /uri-res/N2R? were not properly recorded/persisted.
- (2002.08.27 Richard)
* Moved vendor code resolving to vendors.[ch]
* Added ARES to known vendors
* Juggled includes:
- All GUI modules should include gui.h
- All CORE modules shound include gnutella.h
- Both, gui.h and gnutella.h include common.h
- Any module included by common.h may not include any module from
the GUI or CORE.
Later we will moved files belonging to the different sections of
gtk-gnutella to sub-directories.
* Moved more gui initialization and shutdown code to main_gui.c
* Moved main gui timer to main_gui.c
* Moved loading of legacy config file to main_gui.c
* Moved search_extract_host from search.c as node_extract_host to nodes.c
* Display message in statusbar when manuall connection to node failed
* oldconfig.c is now considered GUI code (needs to access gnet and gui
props)
* Properly update GUI when listen_ip or listen_port changes
* Moved all code from share_gui.[ch] to monitor_gui.[ch]
* Moved gui_new_version found as version_new_found to version.c
* Removed gui init calls from share.c
- (2002.08.26 - Vidar)
* Added a node whitelist. Listed entries will always be allowed a
connection, and we will actively try to stay connected to them.
- (2002.08.26 - RAM)
* When cloning downloads, was properly duplicating "push state" of the clone.
* Fixed assertion failure when bumping into a BUSY chunk (fixes bug #600272).
* When HTTP/1.1 download chunk is done, mark it as "Chunk done" and not
as "Completed" to avoid confusion.
* Fill in Range column of downloads with the actual range requested.
- (2002.08.26 Richard)
* Added Vidar to the "About" dialog
* Fixed minimum speed callback in search pane (connect after now)
* Adjusted lots of files to the new function names exported from
search.[ch] and search_gui.[ch]
* Moved all GUI code from search.c to search_gui.c and have them
communicate via callbacks. Still there is work to do cleaning up
includes and function naming.
* search_xml.[ch] are now considered GUI code. As are filter.c, filter_gui.c
and filter_cb.c, since the saving/restoring of searches/filters and all
the filtering takes place inside the GUI. The backend is only responsible
to collect search results and push it to the GUI.
* search.c and nodes.c use a g_hash_table now to resolve handles and don't
map the internal pointers directly as handles.
* current_search is no longer exported and must be accessed through
search_gui_get_current_search().
* __search_send_packet uses minimum speed setting from search and not
global default minimum speed setting.
* Moved from gnet_props.ag to gui_props.ag (reset to default on startup):
- PROP_MINIMUM_SPEED (now PROP_DEFAULT_MINIMUM_SPEED)
- PROP_FILTER_DEFAULT_POLICY
* Added "Range" column to active downloads
* Move lots of callbacks from callback.[ch] to search_cb.[ch]
* Clobbered some more unwanted includes in several files
- (2002.08.25 - RAM)
* Use /dev/urandom to initialize seed on systems that have it.
* Skip empty lines silently when retrieving banned mesh entries.
* Added support for HTTP/1.1 connections on downloads.
* Swarming code now uses persistent connections and tailored range requests
when remote server is known to support HTTP/1.1.
* GUI will now report proper completion speed for the range requested.
* Could think we were disconnected from the Internet when not making any
outgoing connections, whilst still receiving some.
- (2002.08.24 - RAM)
* Fixed style issues in fileinfo.c.
* Mark changes to the dl_by_time list so we know it was modified when we
are iterating through it.
* Converted download mesh to zone allocator.
* Added banning mesh to avoid filling the mesh with URLs we know are bad.
- (2002.08.23 - RAM)
* Properly reparent all downloads after a file_info_recreate() call which
creates a new fileinfo structure to supersede the old one.
* Dump handshaking header on misparsing to stderr, if debugging.
* Fixed misparsing of header fields: allow spaces before the ':' separator.
- (2002.08.23 - Vidar)
* Added a missing status reset in search.c, which should fix the wrongly
set Push flags.
- (2002.08.22 - RAM)
* Refactored scheduling of chunk ranges, and re-enabled checks for completed
file in the "done" directory when swarming.
* Detect disconnection from Internet sooner: 150 seconds instead of 300.
* Doubled allowed max line size and header sizes because too many broken
servents don't use header continuations yet, although it's a standard!
- (2002.08.22 - Vidar)
* Fixed Search Monitor to display urn:sha1-queries properly.
* Changed fileinfo.c to use hashes instead of a linked list.
* Made manual node 'Add'ing accept a ":port" suffix.
- (2002.08.20 - RAM)
* Integrated Christophe Tronche's patch to schedule alternative sources
from the download mesh.
* Stopped downloads now get requeued immediately and no longer lag in the
upper pane.
- (2002.08.20 - Vidar)
* Added fuzzy autoselection in Search pane.
- (2002.08.19 - RAM)
* Suppress warning about "truncated fileinfo" when file was empty.
* Use SHA1 to create a decent random seed, portably (no use of /dev/urandom).
* All bytes of message GUID are now random: removed internal message counter.
- (2002.08.18 - RAM)
* Defer disposal of vendor string in nodes for GUI display.
* Added duplicate detection and eviction in fileinfo retrieval.
* Only sync metainfo to files every 10 seconds or so, not at every write.
* Fixed the crash when aborting a stopped download.
* Try to smartly ignore the Push flag and attempt direct connection, since
many broken servent wrongly set the flag.
* Stop scheduling downloads when we detect we're no longer connected.
* Query hit parsing now resets Push flag on servers known to wrongly set it.
* When comparing filesizes for auto-downloads, account for the possible
swarming trailer within the "download" directory.
* Fixed stupid typo in atoms that caused final memory fault.
* Forgot to dispose of file_info structure during final download shutdown.
* No need to flush fileinfo trailer when resetting chunk states for downloads
that are moved back to the queue.
- (2002.08.17 - RAM)
* Integrated swarming patch from Vidar Madsen.
* Will now drop query hits with bad SHA1 records.
* Obsoleted "appconfig.h". Superseded by the new property system.
* Ensure `search_table' is initialized early in the process.
- (2002.08.15 - RAM)
* Re-organized firewall detection code, and added Internet connection
monitoring.
- (2002.08.15 - Richard)
* Support NULL as default value of string properties.
* Fixed default listen port (typo)
* Don't display "no new version" in the statusbar all the time.
* Set default min/max values (0x0000000/0xFFFFFFFF) for guint32
properties when not specified in .ag file.
* Ignore incomplete number-vector config lines when reading in
legacy config file.
* Check value of PROP_NODE_SENDQUEUE_SIZE when PROP_NODE_SENDQUEUE_SIZE,
PROP_SEARCH_QUERIES_KICK_SIZE or PROP_SEARCH_ANSWERS_KICK_SIZE are
changed and adjust when needed.
* Mapped more properties in GUI.
* Debug levels configurable from GUI.
* Makefile target to generate sources from the glade file is now
glade_files in both Makefiles.
* Fixed bug: changes to bandwidth settings have no effect.
- (2002.08.14 - RAM)
* Send them back a "501 Method not implemented" if we can't figure out
what they send and we see the string HTTP somewhere.
* When listening port changes, move back to firewalled state
(fixes bug #594477).
* The "is_firewalled" flag is now handled by the property system.
- (2002.08.14 - Richard)
* Updated scan extensions (Affects 583093)
* Changed label of the "remove downloaded" checkbutton to explain that
we only mean to remove items manually selected for download.
(Closes 594503)
* Changed tooltip texts of "firewalled" and "not firewalled" icons.
* Added preliminary configuration interface and properties for swarming.
* Made callbacks for GtkToggleButtons and GtkSpinButtons automatic and
generic when connecting them to the property system. Callbacks for those
widgets are not defined within Glade, but added automatically when the
widget is bound to a property.
* Always update vendor and protocol information when updating node information.
* Removed all spinbutton callbacks which modify a property from settings_cb
and from the glade file and add callbacks for them manually in
settings_config_widget(). All call a common callback function which makes
use of the property map in settings_gui. Some special cases are filtered
out in this common callback function (spinbutton_adjustment_value_changed).
- (2002.08.13 - Richard)
* Introduced property system. A property can be monitored for changes.
They are defined in the gui_props.ag and gnet_props.ag files. From those
the actual C sources are generated with autoconf. Properties can be
persistent and thus make the old config.c obsolete. oldconfig.c acts
as a legacy config loader. If none of the new config files are found,
it will read in the old config file and save to the new ones on exit.
The tooltips of widgets and (where applicable) the bounds of values
enterd into the widgets are also read from the property definitions.
* Creating a separation layer between GUI and core. The property system is
part of this. gnet.h contains the core API and common definitions.
* Added 'properties' target to Makefile to regenerate the property source
files.
* Changed all GtkSpinbutton callbacks to react on the "changed" signal
instead of the "focus lost" and "activate" signals. (Closes #558906)
* Changed some more GtkEntries to GtkSpinbuttons
* Added "Default reissue timeout" to gnet config pane
* Reissue timeout is configurable individually for every search and
persistent.
* Recoded a lot of the callbacks and moved them from callbacks.c to
various other _cb files, mainly to settings_cb.c
* Recoded a lot of the update calls from gui.c which were responsible
of updating the GUI when a config variable was changed. This is done
via callbacks by the property system now. Moved most of the property-
change callbacks to settings_gui.c.
* Moved other calls which update the GUI when something in the core has
changes from gui.c to nodes_gui.c, search_gui.c or statusbar_gui.c.
* Small changes to various files to make them work with the property system.
* Created custom gtk_spin_button_get_value which parses the value to a
double instead of a float.
- (2002.08.11 - RAM)
* We know that gtk-gnutella hosts support /uri-res if they returned HUGE data.
* Renamed socket_monitor_incoming() as socket_timer().
* HTTP server now at the 1.1 level, supporting persistent connections.
- (2002.08.10 - RAM)
* Added RCS Id expansion to all source files.
* Fixed display of hosts in cache (fixes bug #585830).
* Fixed display of servent ID in the Info column, vectorized flags procesing.
- (2002.08.09 - RAM)
* Forgot to update filename counters when server replied with 301.
* All protocol exchanges now logged at dbg=3.
* When closing node connection, don't log EOF as a failure: stick to the
original BYE condition.
- (2002.07.27 - RAM)
* Finished writing download_redirect_to_server().
- (2002.07.13 - RAM)
* Forgot to initialize GUID in results_set after switching to new
zone allocators (fixes bug #580817).
* Now also triggers "Nothing more to get" when the file to download
is smaller or equal than something we have in the "done" dir,
preventing eclosion of .01, .02 files...
- (2002.07.11 - RAM)
* Installed workaround for the reception of SIGPIPE on broken systems,
despite explicit SIG_IGN action (but does not fix bug #578151).
* Added zone allocators.
* Forgot to send "Content-Range: bytes */size" on HTTP 416 errors.
* Refactored download scheduling queue for scalability.
* Optimized pattern matching and searches further.
* Remove assert in gmsg_cmp(), a routine called many times!
- (2002.07.11 - Richard)
* Fixed segfault when creating new IP rule
* Fixed some widget names in filter_gui.c which caused the wrong
widgets to be updated when editing a size or text rule.
* Fixed "widget not found: popup nodes remove" warning
- (2002.07.10 - Richard)
* Fixed two serious typos in filter_gui.c causing removed filters
to be removed from dialog. gtk-gnutella would crash when selecting
such a filter.
- (2002.07.09 - Richard)
* Have two versions of share_gui (API compatible), one for Gtk1 using
a GtkCList and one for Gtk2 using a GtkTreeView (GtkListStore)
* Optimized redrawing of download queue.
- (2002.07.09 - Richard)
* gtk-gnutella is now compatible with Gtk2. To compile against Gtk2,
use the --enable-gtk2 switch with the configure script.
* Now have two glade files, one for Gtk1.2/Glade 0.6.4 and one for
Gtk2/Glade 1.1.0. The format is not trivially upgradable, so for
a while changes will have to be maintained in both files, until
we abandon Gtk1.2.
* Remove the extern.tcl HACK. Now using the Glade-way of doing things
with a lookup_widget() call.
* Also now have interface-glade[12].[ch] and support-glade[12].[ch].
Depeding on which version of Gtk you compile against, the one or
the other will be included in gui.h and linked against. Don't
include any of the files directly, include gui.h instead.
* Added some _gui.h files. The gui.[ch] files are too monolothic and
there are still gui calls in some backend files. Those should be
moved to the corresponding _gui.[ch] files from now on.
Actually we will need 3 files:
- backend (model: what will one day become the lib/deamon api)
- gui (view: gui modification/update and callbacks)
- control (controller: application workflow)
Backend and gui should not communicate directly with each other, but
must call the control layer to mediate. We should already now try
to separate into gui and backend parts. The control layer is still
spread across the callbacks and what we now have as "gui.c" or
"_gui" files.

the queue as well.
* Avoid needless display flickering in search screens [From Richard].
* During shutdown, make sure we neither accept nor make Gnet connections.
* Ignore XML size in QHD for Swapper.
* Remove freeze/thaw calls to node clists during update.

Highlight of changes (user-visible):
- Bug fixes and slight improvements.
- Greatly enhanced auto-selection in searches to use far less CPU.
- Will now warn user when encountering a newer version of gtk-gnutella.

- (2002.07.01 - RAM)
* Added configure check for mandatory zlib.
* Was wrongly stopping at GGEP magic byte when grabbing XML extension.
* Optimized GUI update of node information, traversing list once only.
* When closing a search, remove pending messages from all the search queues.
- (2002.06.30 - RAM)
* Tuned auto-selection in search window to be an O(n) algorithm instead
of O(n*n), which greatly improves performance [From Richard].
* Protected a few pong-cache warnings, so that they be emitted only
when running in debugging mode.
* When removing completed downloads from queue, also remove first-order
aliases by SHA1, if available.
* Fixed upload crash when we can't send back the whole HTTP status
[From Paul Cassella].

* Added hardwired list of servent GUIDs to ban for push routes.
* Now banning GUID "20d262ff0e6fd6119734004005a207b1" for push routing.
(this GUID seems to be bundled as a constant in Morpheus)
* Rationalize right-click menu handling in all panes [From Richard].
* Fixed crashes with the filter popup window when search was closed
before the filter popup [From Richard].
- (2002.06.28 - RAM)
* Portability fix in socks v5 code [From Bruce Momjian, patch #574919].
* Portability fixes for FreeBSD [From Aron, patch #574111].
* Can now enter an urn:sha1: search directly (will beep if invalid).

of file descriptor.
- (2002.06.27 - RAM)
* Stop all processing for 0.4 handshaking after Tue Jul 1 00:00:00 2003.
* Added configure check for glib >= 1.2.10 [From Richard].
* Make sure GUI configuration for download overlap does not exceed the
size of the socket's buffer [From Richard].

version than itself.
* Fixed base32 decoding to use gint8 instead of gchar to be sure to
get signed characters.
* Removed heartbeat warnings about skewed clock when not debugging.
* Fixed dynamic upload slots spinbutton sensitivity (fixes bug #574592)
[From Richard].
* Changed getdate to parse dates as DD/MM/YYYY, not as MM/DD/YYYY.
* Fixed Gnutella size reading in message headers: alignment constraints
would cause a bus error on some CPUs.
* Added configure check for strcasestr(), which is present on some systems.
* Better seed the random number generator.
- (2002.06.25 - RAM)
* Did not include proper gui.c version in 0.90 beta.
* Do not abort when regular expression in queue matching is invalid!
* Avoid using all file descriptors for banning. Now configurable via two
new config variables, namely ban_max_fds and ban_ratio_fds.
* Fixed bug in dmesh_url_parse(), caused by buggy sscanf(), grrr...
# v 0.90 2002.06.24 [beta]
History of changes since 0.85 stable:
- (2002.06.24 - RAM)
* Debian package now requires glib1.2 >= 1.2.10.
* Added warning in dmesh_alternate_location() in case we overflow buffer.
Also check returned val from g_snprintf() to account for trailing NUL.
* Integrated Richard's filter cleanup patch.
* Added nicer servent name for two new servents: RAZA and SWFT.
* Mark callout queue event as freed to avoid memory corruptions in case
of misuse (i.e. usage bug).
* Forgot that dm_expire() could empty the mesh entry (fixes bug #573027).
* Fixed buggy node_remove_non_nearby() (closes bug #572918).
* Added vendor information to warning about improper pong-caching.
- (2002.06.23 - Richard)
* Added RETURN back to filter tree on request
* Enabled stats for RETURN
* Free rule clipboard before exiting to prevent dmalloc from suspecting
a memory leak.
* Update credits
* Made vertical scrollbars at some points always visible to reduce
flickering
- (2002.06.23 - RAM)
* Forgot that scheduling in callout queue uses milli-seconds units: was
purging uploading mesh info too often. Also added mesh info traces.
* Added periodic savings of the search/filters.
* Saving of search.xml is done to a .new file, renamed upon success,
to prevent one loosing precious data in case of a crash whilst saving.
* Forgot to clear callout queue callback info before freeing structure
(fixes bug # 572800).
* Fixed root cause of GTK critical warnings regarding progress bar.
* Forgot to include Alex Bennee in AUTHORS.
* Make sure we detect a duplicate node connection before dropping a node
in favour of a local one (fixes bug # 572748).
- (2002.06.23 - Richard)
* Also set foreground color for root nodes and builtin targets in
filter dialog
* Removed "search again" items from download/queue popups
* Correctly unselect when doing a "connect to host" on download/queue popup
* Don't display RETURN target in filter tree. Stats don't work properly
and it's actually a metatarget which is not intersting to see.
* Removed coloring of builtin targets in filter dialog because I can't set
the foreground of the leave node.
- (2002.06.23 - RAM)
* Fixed size computation problems when generating alternate location header.
* Now displays Server name in downloads as soon as it is known. Previously,
it needed to be known beforehand (from a previous try) to be displayed.
* Obsoleted old "autodownload" feature, since we now have more flexible
download selection features with the filter chains.
* Mesh information will now only be sent to uploaders when a change occurred.
* Christophe Tronche was missing from AUTHORS.
- (2002.06.23 - Richard)
* Fixed bug: active downloads not unfreezed after "force push"
* Mark active "push mode" downloads and "always push" downloads in queue
* Tagret combos are correctly updated when adding and removing a filter
* "About" box added.
* Added builtin targets to filter tree to have the stats (not selectable)
* Added stats to builtin targets
* Remember node state in filter tree
* BEEP if user tries to create filter with invalid name (empty or filter
with same name does already exist) It's not a problem to have two
searches for exactly the same though.
* added filter_find_by_name_in_session routine to filter.c (used to
determine wether a filter name is valid, i.e. does not exist)
- (2002.06.22 - RAM)
* Fixed memory leak in search queues.
* Fixed possible use of uninitialized value in analyse_status().
* Added debugging traces in huge.c cache flushing... Which made the
problem I witnessed go away.
* Unplugged non-functional QRP stuff.
- (2002.06.22 - Richard)
* Added STATE rule which uses the DOWNLOAD and DISPLAY filter result
properties for the condition.
* Added RETURN target to filter dialog. It aborts the processing of the
current chain returning to the caller.
* Make filter root-nodes in filter dialog not selectable
* Builtin filter targets have uppercase names.
* Removed cruft: search_strict_and
* Synced GUI limits with config reader limits. (Closes #557681)

This is to be replaced by the filtering system.
* More cleanup of the config.c file
* Rule count in filter tree is correctly updated when a rule is
inserted/removed.
* #527208 is closed since autoselection does respect hashes since
a few days.
* Hopefully now really fixed: access rule members after freeing the rule in
filter_replace_rule_in_session
* Added filter_gui_update_rule_count call to filter_gui
* Rename old searches file when moving to XML mode instead of delting.
Also move this from search_init to search_shutdown.
* Item count above results list is correctly updated when the
search is cleared.
- (2002.06.22 - RAM)
* Bandwidth limit is now up to BS_BW_MAX, included.
* Now attempts to free memory as soon as a search record is removed from
the GUI, and not when the search is closed.
* Would be omitting to send a SHA1 starting with a leading NUL byte.
* Forgot to clear the node's search queue at final cleanup.
- (2002.06.21 - Richard)
* BUG: access rule members after freeing the rule in
filter_replace_rule_in_session
* Added popup to rules list in filter dialog (copy/paste rule)
* Made filter_free_rule public
- (2002.06.21 - RAM)
* Forgot to free dmesh slots sometimes.
* General cleanup to be able to compile with dmalloc.
* Watch out the g_snprintf() return code: it can return more than the
buffer size with glibc >= 2.1.
- (2002.06.20 - RAM)
* Was not properly parsing more than one GGEP extension block in a row.
* First take at download mesh implementation, with code refactoring.
* Lowered max banning period to 3 hours, instead of 1 whole day.
* Removed the gnotella.fileflash.com host cache: host no longer exists.
* New date_to_iso_gchar() to emit the ISO date for the download mesh.
* Now keeps track of the time we received the query hits, for the
download mesh.
* Simplified parsing of the query hit trailer, keeping only the vendor
code around instead of the whole trailer. Adapted sorting algorithm
accordingly.
* shared_file_by_sha1_base32() is no longer used (share.c).
* New url_escape_into() routine (url.c).
* HTTP status parsing routine now called http_status_parse().
- (2002.06.20 - Richard)
* Bug: segfault during autoselection (NULL rowdata) (Thanks Daniel)
* Filtering now supports multiple properties to set (display/download)
* Added "Auto-download by [name|hash]" to search popup
* Changed valid values for the filter_default_policy config value from
0,1 to 1,2 (mapped on load for backward compatibility)
* Changes in filtering code make all filter stats count double
(one count for every property).
* merges search_gui_update into search_matched (search.c)
* split search_gui_add_record out of search_gui_update
- (2002.06.17 - Richard)
* Bugfix to "Autoselect identical" is handled
* Column visibility is persistant in search panel
- (2002.06.16 - Richard)
* Added ability to filter by urn:sha1 and by flags (push, stable, busy)
(urn:sha1 filter is not editable yet)
* Added "Don't show results with urn:sha1" to search popup
* Added "Edit filter" back to search popup
* Changed header of urn column in search results to "urn:sha1" and
centered it
* Added "Abort all with urn:sha1" to downloads and queue popup.
* Made the download_remove_all* return the number of removed downloads
* Display the number of removed downloads in the status bar
* Freeze queue and downloads list when acting on a "Abort all..."
* When a new rule or filter is added, display "new" instead of
"none yet" in the stats column to show that this filter will
not be used unless the user closes the filter dialog with "Ok".
* Started to use scid_info for general temporary information in
the status bar.
* Make autoselection also select files with the same hash as the
selected in addition to those with the same name
* Added "Globally drop results with [name|urn:sha1]" to search popup.
I wanted to be able to drop definite spam once and for all.
* Netmask for ip filter rules defaults to 255.255.255.255
* Column visibility in search pane now affects all searches
(internally the visibility state is propagated from the old to
the new clist on a switch)
* Added "Autoselect identical" checkbutton to search pane.
- (2002.06.15 - Richard)
* Added URN column to the search results (hidden by default)
* Made gui and backend use same code for comparing records
(search_compare).
* Made passive searches persistant
- (2002.06.15 - RAM)
* Propagate SHA1 from query hits to download requests.
* Now recognizes old base32 encoding, translated into new one.
* Had not properly plugged in the 301 Moved triggering for uploads.
* Until we have received a message from nodes, handle them with the
"connecting" timeout. This works because of the handshaking ping.
* Reworked upload HTTP parsing so that we can handle HEAD requests on
/uri-res/N2R? queries as well.
* Download code will now honour 301 Moved replies from other nodes.
* Added debugging traces for queries/hits holding more than 32 extensions.
- (2002.06.13 - RAM)
* Added rigorous extension parsing.
* Fixed hash table init for GUID/SHA1 atoms.
* Make sure we use POSIX extended regular expressions.
* Added strcasestr() routine to misc.c.
* Now extracts SHA1 out of query hits for each record.
* Now validates SHA1 representation in queries, dropping bad queries.
* Fixed handling of GET /uri-res/N2R: the "urn:sha1:" part is a
case-insensitive string. Likewise when extracting SHA1 from HTTP headers.
- (2002.06.11 - Richard)
* Fixed bug: default filter not set on passive searches.
* Fixed bug: rule editor not properly cleared when work_filter
gets removed because it's bound search got removed
* Fixed bug: filter dialog size not remembered correctly
* More clean up of the filter api
* More moving gtk code to from filter.c to filter_gui.c
* Adding/removing of filters is also shadowed now (meaning you can
cancel it in the dialog)
* Added calls to bypass shadowing for adding and removing rules.
* Added "Don't show selected" to search popup. This adds a drop rule to
the search filter for all files which match exactly the filenames from
the selected records. It does not jet check for duplicates.
- (2002.06.08 - Richard)
* Remove optionmenu widget for selecting filters from filter dialog
and added a tree instead.
* Filters can now be deactivated
* Added some buttons to reset filter/rule stats
* Started to split up callbacks.c/h and filter.c/h and created
filter.c (controller), filter_cb.c (callbacks) filtler_gui.c
(gui calls). This is a first attempt to seperate backend from
frontend calls so we don't fix something up now and tear it
apart later. Better try to do it right from the start.
* Fixed bug: bw_ul_usage_enabled was not properly persistant
* Added general macros to set/clear flags to misc.h
* Added a flag_t type for storing flags binary (use with above macros)
* Filter stats update periodically
- (2002.06.07 - RAM)
* Added atoms, allowing sharing of common constants.
* Made callbacks.c use new gui_allow_rescan_dir().
* Raised default TTL to 7 (was 5) and default max TTL to 10 (was 7) to
match what appears to be a common setting in other servents.
* Plugged in atom strings for downloads.c, huge.c, main.c, search.c,
share.c and uploads.c.
* Moved Gnutella query message definitions from search.h to gnutella.h.
* When non-local nodes are removed to favor local ones, send BYE 202 messages.
* Second stab at QRP: Computes routing table patches incrementally.
* Now requests URNs in all our queries.
* Reworked library scanning to use atoms, and in particular store the full
file path as an atom (shared with huge.c in the SHA1 cache).
* Added support for transparent index remapping for older servents sending
a request with an incorrect index.
* Made common warnings in sockets.c silent unless debugging enabled.
* Fixed improper dump of incoming data on first long lines.
* Send a 301 Moved with proper Location redirection when requesting a file
with an improper index and an X-Gnutella-Content-URN is given and does
not match the request, but another file we have.
* Added incremental deflating routines for QRP patch compression.
- (2002.06.03 - RAM)
* Fixed improper semantics of the "contains words" filter. ALL the
words must be present for a match to occur.
- (2002.06.02 - Richard)
* Format of RULE_SIZE display string changed.
* Added "Create filter" button to dialog.
* Normalize upper/lower value in filter_new_size_rule()
* Replaced all g_message calls with printf (fixes log corruption)
* Filter rules can now be deactivated
* When a filter has the "don't display" target, the user may choose
to grey out the result instead of completely dropping it using the
"mark only" flag.
* Make filter dialog size persistant.
* The xml backend gives better information when unable to read in the
xml file and can cope with missing rule flags.
* Information about how often a rule matched is displayed in the
filter dialog (but not updated periodically)
* Fixed default filter selection when adding a new search.
- (2002.06.02 - RAM)
* Added build dependency on libxml2-dev in debian control.
* Force --enable-xml-store in debian's build.
* Will now prevent propagation of badly formed/too short queries.
* Replaced more gtk_idle_add() calls with g_idle_add().
- (2002.06.01 - Richard)
* Disabled xml backend by default. Use "configure --enable-xml-store"
to enable it. You need libxml2 and libxml2-dev packages installed
for it to work.
* Fixed bug: assertion failure when trying to edit filters without
any search existing.
* It's no longer possible to edit the builtin filters (was a bug
that this was possible).
* Added widgets to configure the minimal upload b/w percentage patch
[From Tobias Frech] to the bandwidth config panel.
* Changes build scripts to remove dependency on gnome-config and
added checks for libxml2.
- (2002.05.30 - Richard)
* New filter code and dialog.
* Moved from callback.c on_search_switch as gui_view_search to gui.c
* Changed searches list from GSList to GList.
* Use search_t instead of struct search.
* Began to move search related gtk code to gui.c (gui_search_close)
* Optionally use xml backend or simple text file for makeing searches
persistent.
* Use "search_close" instead of manually closing searches in
search_shutdown().
* Changed handling of "minium speed" widget. You can change the minimum
speed on a existant search and change the default minimum speed on the
gnutellaNet config pane.
* Moved the gui part of removing a search from search.c to gui.c
* Removed macro definitions of the notebook page numbers
and switched to enums.
* Moved main_window and shutdown_window to gui.c and have them as externs
in gui.h
* Added gui_show_search(search).
* Added some functions to handle option menus more easily (gtk-missing)
- (2002.05.29 - RAM)
* Added date parsing.
* Now parses Retry-After in HTTP replies, supersedes user-defined timeouts.
* When banning, emmit a Retry-After header.
* Renamed getdate() to date2time() to avoid conflict on Solaris.
* Integrated minimal upload b/w percentage patch [From Tobias Frech].
- (2002.05.27 - RAM)
* Fixed ipf_unban() to test rounded integer counter and not float in removal.
* Was not properly updating SHA1 info when library was being rebuilt.
* Was not properly sending back urn:sha1 in query hits (truncating the
':' separator).
* All SHA1 digests are now stored in binary internally.
* Added padding chars to base32 encoding, and "const" in the signatures.
- (2002.05.24 - RAM)
* First stab at QRP. Computes the routing table, but it is not used yet.
* Added QRP message definition.
* Callout queue is now a global service and is initialized from main.
* Scan library after GUI is brought up.
* Was not accounting Gnet header traffic as Gnet bandwidth.
* Added anti-hammering feature, that will ban users sending more
than 10 requests per minute (sliding window).
* Always honour HEAD requests, even when busy, provided no hammering.
- (2002.05.24 - Richard)
* allow shrinking of main window to smaller then minimum size required
by the child widgets
* Added a optional search list to the sidebar. Displays: search name,
hits, new hits (number and color), paused searches (color)
* Made tree menu resizable in both directions.
* Added "copy url" item to queue popup
* Added "connect to host" item to queue and downloads popup
* Added "configure columns" item to search results popup.
Note: the visibility state of the colums is not persistent, this
is only a proof of concept for the selection widget yet.
* Carry information about which tab is associated with which menu item
from the tree menu directly in the user_data of the node instead
of in a static array.
* Freeze clists during all actions which take place on the the selection.
* Replaced g_assert(0) with g_assert_not_reached() where found.
* Made "unselect" signal callback for downloads and queue call the
"select" signal. Same actions needed.
* Instead of unrealizing and removing the arrow widget, just destroy
it.
* If the tab in notebook_main is switched, the tree menu reflects the
change.
* Fixed bug which caused both, "firewalled" and "not firewalled" icons
to be displayed when hiding and then showing the statusbar again.
* Increased default sidebar size to 128 pixels. (closes #558890)
* Almost finished cleaning up config.c. The config file looks much
cleaner again.
* Use gtk_events_pending() instead of g_main_pending() in gtk_main_flush().
* Add hack to set the internal column name in a clist. Currently this is
needed for the GtkColumnChooser widget to work properly.
* Moved menu initialization from main.c to gui.c. This means most of
the gtk stuff is now removed from main.c
* Added more enums to gui.h to describe important gui values (like
giving names to notebook pages)
* Moved the updateing of the traffic stats from gui_update_global() to
gui_update_traffic_stats and only call it in the main timer. No need
to call it more often (gui_update_global is called from some callbacks
and stuff).
* Made notebook tabs in search results tab not hide if there is no search.
This had conflicted with either showing tabs or sidebar list.
- (2002.05.21 - RAM)
* huge.c: cast all file sizes to long before printf("%ld") since some
machines have 64-bit off_t (but Gnuetlla only has a 32-bit field for
propagating file sizes, so it does not matter).
* Forgot to emit initial header when appending values to disk SHA1 cache.
* Hacked a quick fix for the duplicate SHA1 work problem.
* downloads.c and huge.c: Another batch of off_t args cast into gulong.
* Added UTF-8 decoder for queries, and transformation to ISO-8859-1.
The query text are now interpreted as ISO-8859-1 by default, unless
the query "looks like" UTF-8. In any case: no full Unicode support.
* Fixed search statistics scheduling mess, and removed spurious main
initialization since GUI settings already triggered search_stats_enable().
- (2002.05.20 - RAM)
* When queuing a download from the same GUID/file, check the IP:port in
case it changed since we queued it, and not solely reject it as a
duplicate.
* When the full SHA1 hashing credit is not used, do not perform the
feedback adjustment, since those assume all the credit was used.
* In share.c: now uses gtk_main_flush() to update the GUI, not the single
loop iteration.
* uploads.c: fixed segfault at shutdown time (dup free of user_agent field).
* Honour X-Gnutella-Content-URN in requests and send a 404 error if
the file we have does not match.
* Will now send back X-Gnutella-Content-URN in the HTTP reply with the SHA1
(if we have it) on 503 Busy errors.
* Applied cleanup patch #557071 [From Uros Bizjak].
* Applied Solaris compile patch #558202 [From Uros Bizjak].
* Applied structure packing, SOCKS error message fix, and cleanup patch
[From Michael Core].
- (2002.05.20 - Richard)
* Switched names of arrow_up.xpm and arrow_down.xpm (closes #558219)
* Added "User agent" column to uploads
* Added "Server" column to downloads and queue
* Display sort order in searches in column header
(closes #557690)
* Remove "stop sorting" from search popup. This can now be achived
by clicking on the column headers.
- (2002.05.19 - RAM)
* Integrated SHA1 / HUGE patch [From Ch. Tronche].
* Force creation of config directory if it does not exist
(fixes bug #557114).
* Don't run file name searches on small query texts when there is an URN
match attempted.
* Keep track of User-Agent and Server in HTTP requests.
* Further adjustments in huge.c:
+ Use glib timeouts, not gtk ones to not needlessly tie to the GUI.
+ Improved timer adjustment feedback to shoot for 3/2 of the max life.
+ Added debugging SHA1 computation rate traces.
- (2002.05.19 - Richard)
* Removed "clear queue" button. This is not necessary. To clear the
whole queue, just use a empty regex to select all and then use
"abort" from the popup menu. We don't want people to accidentially
purge thier queue.
* Made non-editable entries sensitive, so that at thier content is
copy-pastable.
* Increased sleep time during shutdown to 200ms again, but process any
pending Gtk events before sleeping.
* Made size of sidebar (menu, stats) persistent.
* Changed tooltip text for the "local netmask" stuff.
- (2002.05.18 - RAM)
* Improved shutdown code to avoid segfaults in grace period and deny all
pending Gnet connections cleanly.
* Moved pong-caching code to pcache.c.
* Reorganized the way we detect that BYE was sent, and added support for
probing the size of the TX stack.
* Pay attention to GUI settings for bandwidth limitation before enabling
the corresponding schedulers: only do so when they explicitly wish
to limit traffic (provided allocated bandwidth is >0).
- (2002.05.17 - Richard)
* Fixed bug: drag in queue while queue is freezed unfreezes queue.
* Reflect freezeing of queue in the gui (as would explicit freezing).
* Reduce min value for listen_port to 0 in glade.
* Display notice window when shutting down.
* Made menu expand and used gtkpaned so size of sidebar can be changed.
Size is not yet persistent.
* Removed stream button from search panel since unused.
* Tried to fix problem with segfault during shutdown and thus
disabled timer calls in main timer for things that were
already closed (uploads/downloads) during grace period.
Failed miserably because we still have a segfault.
- (2002.05.17 - RAM)
* Applied enum/macro cleanup patch #555837 [From Uros Bizjak].
* Display download queue status entries.
* Fixed guess_local_ip() to never replace a previous non-private IP with
a private one.
* Added exit grace period to make sure final BYE messages get a reasonable
chance of being sent.
* Added extended copyright notices, per FSF recommendations.
* Added copy of the GPL in the LICENSE file.
- (2002.05.16 - Richard)
* The position of the divider in the downloads pane is persisitent.
Attention: I implemented the missing gtk_paned_get_position function
and it has the same name as the GTK2 function will have.
* Started to tidy up config file
* Hopefully fixed sourceforge bug #555758: Crash when drag lasts too long?
Catch the drag signals and freeze the queue during drag. This prevents
items to be removed from the list during the drag which I think was
the cause for the crash.
- (2002.05.15 - Richard)
* Fixed bug with spinbuttons: manually entering a value did require
to hit enter two times or did not work at all. Had to use
connect_after() to connect the signals.
* Save width of "Status" column added to queue.
* Display notice in the statusbar if the address has changed.
* Added gNet traffic display and reworked the View menu and stats
display a little
* Replaced the hosts_in_catcher entry with a progressbar.
* Changed some limits on the new configuration items.
* Obsoleted all *bps* config variables and replaced them with
*bws* counterparts to reflect the internal changing of names
within bsched. Kept code to load the values from the *bps*
variables though.
* Added configuration of gNet bandwidth control
- (2002.05.14 - Richard)
* Added lots of config stuff.
- (2002.05.14 - RAM)
* Added traffic compression ratios.
* Added support for Gnet bandwidth limiting (core only, no GUI settings).
* Fixed flow-control problems on TX stack.
* Fixed assertions on search sending to account for initial random hop count.
- (2002.05.12 - Richard)
* Added "Status" column to queue. Not working properly yet.
* Added icon to display "firewalled" and "not firewalled"
status in statusbar
* Change spinbutton support from using int to using float.
* Fixed decimal values in the bandwidth settings
* Unselect all before using regex to select (more intuitive)
* Updated debian/substvars: added depends on zlib1g
- (2002.05.12 - RAM)
* Removed debugging warning on Z_BUF_ERROR when TX flushing.
* Search stats configuration unit is now the second.
* Fixed assertion failure in deflate_rotate_and_send(): the culprit
was deflate_nagle_timeout(), calling that routine without checking.
* Added Debian build dependency on zlib1g-dev (in debian/control).
* Compressed node traffic indicated by TXc and/or RXc in Info field.
* Fixed typo in cq.c that caused hash bucket chaining to be mixed up.
* Fixed order in the CH_INSERT_AFTER macro that was corrupting tail too
early (forgot it was a macro, and not a function call).
* Made destruction of the RX stack a true depth-first operation.
* The RX inflater will stop delivering packets as soon as RX is disabled.
* The TX deflater writev() routine was not accurately detecting flow-control.
* Need to dispose of the RX stack asynchronously, not on the interrupt stack.
- (2002.05.11 - Richard)
* Added a saftey call to disable the tabs of notebook_main even
if left on in glade.
* Added "local node" information to the main nodes display.
* Added boxes around the queue and downloads frames, so the vpaned
scales better.
* Changed "Remove all matching regex" to "Select all matching regex".
* Renamed some config variables and widgets to get better naming
consistency.
* Changed "Listen port" and "proxy port" to spinbuttons.
* Added "Enable autoselect" to search panels. This binds to the
search_pick_all config variable.
* Made missing checkbutton states persistent.
* Added some macro magic to gui.c, config.c and callbacks.c. More readbility,
less writing effort.
* Moved updating of gui widgets at startup from config_init() to
gui_update_all().
- (2002.05.11 - RAM)
* Allowed "configure --enable-no-rfc1918" to default to off (was forced on).
* Exported bsched_disable().
* Re-architected RX stack.
* Added first support for Gnet traffic compression (still some rough edges).
- (2002.05.08 - RAM)
* Ensured no line is longer than 80 characters in main.c and gui.c.
* Dynamically setting bandwidth to 0 prevented all traffic instead of
disabling bandwidth limiting.
* Even if bandwidth scheduler is disabled, go through the EMA computation
of the bandwidth actually used, for GUI display purposes.
* Added Roles section to the AUTHORS file.
- (2002.05.07 - RAM)
* Now that local_ip is persistent, we need to refresh it regularily in case
it changes from one invocation to the other, and not always trust its
persisted settings.
* Changed "Shutdowning" -> "Closing".
- (2002.05.07 - Richard)
* Added "Remove all matching regex from queue" to downloads panel
(case sensitivity is not persistent yet)
* Fixed memory leak in dialog-filters.c regex handling code
(g_free(re)).
- (2002.05.04 - Richard)
* Added "Max uploads to single host" to uploads panel
* The usual cleanup of spacings and labels and stuff I came across
* Added preliminary designs of a new filter dialog to the glade
file. No functionality yet. Will probably be redesigned before
actually being integrated.
* Fixed bug: search field does not clear when search is added
* Fixed bug: search tab headers do not update the result count
properly when having "remove downloaded items from list" checked.
* Fixed typo: "QUEUE FROZEN" instead of "QUEUE FREEZED"
* Note: for autocompletition on a GtkCombo (e.g. search combo), try
Alt-Tab. Works in any application.
* moved more code from main.c to gui_init
* removed clist_connections (old stats) from glade and gui code
- (2002.05.02 - RAM)
* Fixed bug #551185: was not initializing local_netmasks_string.
* Fixed bug #552255: could be wrongly freeing static string.
- (2002.05.01 - RAM)
* Integrated the search queue patch: searches are now sent once every
10 seconds on a per-connection basis [From Alex Bennee].
* Was improperly counting duplicates as "bad" messages.
* Now displays both dup/bad message counts in the Info column for nodes.
* Searches now made persistent [From Michael Tesch].
* Got rid of the local-config-file overwriting. All configuration files
are now exclusively saved in the config dir, never locally (unless you
run from that config dir!).
* Fixed bug #538946: was incorrectly moving complete files out of the
done directory. Also, "Nothing more to get" error is now reported if
one tries to downloads a smaller file (it was not flagged as an error,
so the "Completed" message was shown instead of the error text).
- (2002.05.01 - Richard)
* fixed sensitivity of "copy url" in downloads popup
* make search history work (though not persistent)
* added "Remove downloaded items from list" checkbox to search panel
Use this to have items selected for download automatically be
removed from the result list.
- (2002.04.30 - Richard)
* Put statistics into a handlebox so they can be displayed seperatly
from the main window
* Went throught the gui layout and set a consistent layout style:
horizonal spacing: 4; vertical spacing: 2; border: 2
* removing of unnecessary widgets and more clean up of the widget
tree
* make "remove file" in downloads popup work
* removed "abort and delete file" from downloads popup
* made "copy url" really supply an escaped url which should work
when pasted to a browser
* changed the widget for entering search strings in the search panel
from a GtkEntry to a GtkCombo as a preparation to supply a search
history in future.
* fixed sensitivity of several items in the downloads popup which
were sensitive even if they would have done nothing when activated.
- (2002.04.27 - RAM)
* Reversed logic for forced IP, to make it behave properly: the IP is
now only updated dynamically when "force IP" is not checked.
* Added download_remove_file() and download_file_exists().
* Check for new "download_delete_aborted" condition in download_abort() to
remove file when it is set.
* Added debug logging of bad packets, to help diagnose why we receive
bad packets from gtk-gnutella.
* Made nodes.c compile on the Alpha, where varargs objects are different.
(fixes bug #537460)
- (2002.04.25 - Richard)
* moved more code from main.c to gui_init() in gui.c.
* added checkbutton "Delete file on abort" to downloads panel. When this
is on, aborting a download will also remove the associated file from the
hard disk. This is to prevent us from having multiple "Abort..." and
"Abort and delete..." entries in the popup menu.
This functionality still has to be integrated into the download logic.
* remove the "update" button for port configuration on the config network
panel. This entry now behaves just like every other entry (enter or
change focus to accept changes).
* replaced more entries in the config panels with GtkSpinButtons.
* added a "copy url" item to the downloads popup. This can be used to
copy the url of a single download to the clipboard and paste it
e.g. to your browser. This is only selectable, if a single download
is selected.
* added build_url_from_download() to misc.c because of the above
* cleaned up lots of stuff in gui.c, including coding style but mostly
changing the way focus-out signals were handled. Now a focus-out signal
triggers a activate-callback on all widgets to update the program state.
Meaning, we no longer use "grab_focus(menutree)" to trigger a focus-out
event (useless focus jumping). Instead when pressing "enter" on a widget,
the change is accepted and the focus stays where it is.
* more layout in the config panels.
- (2002.04.22 - RAM)
* Always update actual bandwidth used, even when the scheduler is disabled,
so that the GUI can display the current usage whether bandwidth is
limited or not.
* Removed useless SIG_Ignore() signal handling trap, just SIG_IGN them.
* Ignore SIGXFSZ so that subsequent write() fail: if not ignored, that
signal will kill the process.
* Added debugging output for auto-downloads, and refactored list iteration
bits to be more in line with the other uses.
- (2002.04.21 - Richard)
* click on bandwidth stats to toggle display mode (normal/average)
* added "authenticate to proxy" to network config. The associated
config variable is called proxy_auth.
* made bandwidth stats more readable
# change of changelog format to better accomodate multiple contributors.
- made reissue timeout spinbutton on search-pane wider. (Richard)
- made config pane a tabbed pane. (Richard)
- added bandwidth control to config pane. (Richard)
- added support for temporary statusbar messages (Richard)
- reorganized configuration pane (made a tabbed pane) (Richard)
- added gui controls for changing bandwidth allocation in the config
pane. (Richard)
- added indicators for current bandwidth allocation to left panel.
(Richard)
- now really use statusbar contexts and the GtkStatusbar stack features.
(Richard)
- Moved freeze toggle-button out of the context menu and display a
message in the statusbar to warn the user that the queue is freezed.
(Richard)
- added several new popup menu items to popup-download and popup-queue,
but disabled them for now since they are not backed up by code yet.
(Richard)
- removed useless host catcher popup code (Richard)
- added "freeze" toggle button to queue context menu. This can be used to
enable/disable the automatic moving of files to and from the queue
(i.e. disable download_timer). To make this work properly, the
download timer is the only function now to call download_pickup_queued.
(Richard)
- added "kill all named" and "kill all from" to popup-queue and popup-downloads.
These will remove all queued downloads and abort all active downloads
matching any of the selected items. (Richard)
- visually distinguish items in search list that where already selected for
downloading (Richard)
- Added uptime of servent to statusbar. (Richard)
- Modified multiple-selection handling in on_button_uploads_kill_clicked,
on_button_downloads_queue_remove_clicked and on_download_start_now_activate.
This should fix problems where the selection was not actually acted on.
- made popup_queue_start_now (de)activate correctly when maximum
number of downloads is reached (Richard)
- Missed out to hide notebook tabs after modifing the gui.
- Rearranged widgets to reduce minimum window size. On my box this means
604x503 (sorry 640x480 guys... maybe later).
Enabled both scrollbars on nodes list
Closes #540610 (Richard)
- Changed lots of stuff on the gui layout (Richard)
- Changed menu from list to tree (Richard)
- Renamed lots of widgets (Richard)
- Fixed several popup action handlers to cope with multiple selections
(Richard)
- Can add searches from the monitor pane (only if monitoring is off, because
otherwise the selection would be gone too fast).
(Richard)
- Replace numeric text fields (like max no of downloads) with a spinbutton
(Richard)
- Disable autoselection when more that one file is already selected (search).
(Richard)
- Hidden old stats frame (Richard)

- Added progress bars to display connection/upload/download stats (optional)
(Richard)
- Made build-glade target in Makefile really regererate the code from the
gtk-gnutella.glade file by calling src/Makefile glade_files
(Richard)
- Updated Debian's control file.
- Now accounts for bytes transferred in interrupted uploads as well, and in
particular at servent shutdown time.
- When not sharing, return HTTP error 503 instead of 410, since it is a
server-side problem, not a client-side problem.
- When facing an HTTP/1.1 request, make sure there is a Host: header.
- Added routines for on-the-fly bandwidth settings, and access macros for
getting the instantaneous and average bandwidth usage per second.
- Refactoring of network TX layer.
- Display the uptime as either "HH:MM:SS" or "d HH:MM" with blinking ":".
- Optionally favor local Gnet hosts over remote ones, per netmask [Mike Perry].
# v 0.85 2002.04.04 [stable]

- Memory leak fixes.
- Was moving to wrong pane when "jump-to-downloads" enabled.
Detailed changes:
- Define SOL_TCP as IPPROTO_TCP for non-linux machines.
- Added a return to shut up compiler warnings in bio_sendfile().
- Fixed memory leaks in queue.
- Shutdown TX side of socket after having sent Bye.
- Fixed memory leak in uploads, in push request handling (bug #534434).
- Was moving to wrong pane when "jump-to-downloads" enabled
(bug #535000, with fix from Steven Walter).
- Increased receive buffer size for nodes from 48K to 112K.
- Fixed node_sent_ttl0(), which assumed node was kicked-out when Bye is sent,
although it is no longer the case, unless Bye was already sent.
- Will now report error 414, "Requested URL Too Large", when encountered.
- Could mistakenly report 404, "Not Found" when rebuilding library.
# v 0.85 2002.03.23 [beta1]
Summary of changes (user-visible):
- Now support Gnutella traffic prioritization and flow-control for enhanced
stability of connections.
- Can now use an HTTP proxy for outgoing connections, in addition to SOCKS
v4 and v5 proxies.
- When "Force local IP" is ticked, gtk-gnutella will try to automatically
update the value if it detects a change in your IP address.
- Added search statistics.
- Added persistent upload statistics, keeping track of which files were
uploaded by users, and how many times.
- Will now show the size of the uploaded file and the requested range,
under the form "request @ offset" in the Range column.
- Node servent names are now displayed in the gnutellaNet window, if known.
- Bandwidth management for input and output traffic is now possible. It can
only be configured via the config file though, not via the GUI. It only
accounts upload/download traffic, not Gnet traffic.
- Displayed transfer rates are now instantaneous transfer rates, not average.
- Upon completion, uploads and downloads show the time spent in transfer.
Detailed changes:
- Node send queue is now managed as a real queue.
- Added node transmission flow control.
- Routing decisions and actual routing are now two distinct operations.
- Some download control hardwired constants were made config parameters.
- Fixed downloading policy to avoid retrying ad infinitum when the connection
cannot be made at the TCP/IP level (because there's nothing listening).
- Added support for the Bye packet.
- Dispatched heartbeat timer routines to the relevant files.
- Integrated HTTP proxy patch [From Szabolcs Sel�f].
- Properly handle Range requests such as "123-456" and "-567". Still no
handling for things like "123-456,457-789" though.
- Extract and log vendor information of nodes we connect to.
- Fixed improper counting of TX-dropped packets in flow-control as RX-dropped.
- All % completion figures now shown with 2 decimals.
- Since we can now automatically determine our IP correctly, make sure the
"force local IP" parameter is true by default.
- Could be sending pongs with TTL=0 by mistake.
- Was always sending pings with TTL=1 by mistake.
- Initial take at bandwidth management -- can only be configured via the
config file, i.e. once and for all. Gnet traffic does not count.
- HTTP error code 408 is retryable.
- Include Date and Last-Modified headers in our HTTP success replies.
- Switched to real-time download/upload transfer rate and ETA computations.
- Fixed number of columns in search table to 5.
- Fixed bug in handling node_bye() for ponging-only connections (#518822).
- When current transfer rates are too low, switch to average rate for
estimating time remaining.
- More cleanup in the routing code, which fixes a potentially harmful bug.
- Ensure original downloads are saved in downloads.orig, and protect against
sudden death whilst saving.
- Turn on TCP_CORK for uploads, to optimize outgoing bandwidth.
- Makes use of sendfile(2) if available.
- Huge cleanup in routing.c: function renaming, signature changes, assertion
cleanup and comment additions. In particular, removed a wrong assertion,
known as "m->nodes" when failing.
- Trace user interface, OS type, OS version and CPU type in User-Agent.
- In the "Config" page, show total size of files shared.
- Adapted proxy_connect() signature to be able to get it to compile on IRIX.
- Now detects and handles the situation wereby time goes backwards or forwards
due to time synchronization (NTP deaemon).
- Display the time spent uploading or downloading when entry is completed.
- TCP reception buffer is raised to 112K for downloads.
- The default node queue size is now 96K (150% of 64K, the max message size).
- Added support for higher-priority control messages.
- Node statistics now show amount of messages in queue, and percentage of
the send queue filled with messages.
- Alive pings are now replied to with a higher priority pong.
- Tuned flow control to avoid too many memory allocation/free, and saturation
of the queue (lowered high watermark to 50%).
- Now also emits the Remote-IP header when connecting to other nodes.
- Node statistics are now updated once per second on the GUI.
- Added Morpheus (MRPH) to the list of vendor codes.
- Fixed bugs #524773, #524987, #523762, #524988.
- Added Size/Range columns to the upload screen.
- Added Vendor and protocol Ver(sion) columns in the node screen.
- The GUID of a servent is now made persistent and flagged as such, in order
to prepare the possible implementation of gnet: URLs.
- Factorized generation of random numbers into random_value().
- Added search statistics pane [From Michael Tesch, patch #524921].

from explicitely firewalled servents.
- Disable the "Start now" menu entry if we don't have any more download slot.
- Removed broken support for computation of lower-cased directory paths in
the shared library.
- Fixed broken recursive scan of the library, with help from Michael Tesch.
- Ensure we do not launch two copies of gtk-gnutella backed by the same
configuration, and protect any configuration change made whilst the
program was running by saving a copy of the old configuration if needed.
- Fixed push bug, by allowing several downloads to be recorded for the
same (index, GUID) tuple. This can happen if we don't notice a re-indexing
on the remote host.
- Fobid the multicast IP range, and also the new 169.254/16 private range.
Downloads at those addresses will be pushed.
- Don't remove queued downloads whose size is greater than the one we completed.
- When downloading a file bigger than the one in the done directory,
and provided it's on the same filesystem as the tmp directory, move it out
for resuming. This is safe now that we perform range overlapping.
- Changed error message "Route lost" into "Push route lost".
- Don't abort with "Push route lost" when we only fell back to push, but the
address does not seem to be private and there was no push indication in the
query hit.
- Added upload statistics pane [From Michael Tesch, patch #529294].
- Attempt to flush upload statistics on a regular basis when changed.
- Try to flush queued messages on nodes as fast as possible by turning
on TCP_NODELAY to disable Nagle's algorithm.
- Reworked on the shutdowning/bye code to maximize chances of proper delivery
of the BYE indication.
- Must duplicate filenames in uploads in case library is rebuilt, or it will
corrupt the upload statistics.
- Save config and host cache in a temporary file first, then rename as the
final file when everything is OK to avoid corrupting precious data via an
incomplete write.
- Be sure to disable a queue becoming empty in mq_clear() if it was enabled
(fixes bug #530811).
- Split I/O vectors larger than the max allowed size (fixes bug #530106).
- Fixed off-by-one error in url_escape_cntrl() causing memory corruptions.
- When needed, must disable reading before calling node_bye(), in case we're
facing a temporary "ponging" connection, which node_bye() happily removes
(fixes bug #531167).
- Now handle parsing of 0.6 handshake headers on Ponging connections, to grab
any Node: header and fake a pong. This also allows Ponging 0.6 hosts to
be seen in the GUI: they used to be discarded very early in the process,
making display impossible.
- Was mistakenly displaying last offset as size in uploads.
- Negative range requests are offsets from the end of the file.
- Added upload stats "average count" [From Michael Tesch, patch #533257]
(will convert existing stats to the new format).
- Ensure minimum value for node_sendqueue_size (1.5 * max packet size).
- Fixed cornercase, a leftover of bug #530811.
- Fixed crash when upload stats are cleared (bug #533904).
# v 0.80 2002.01.31 [stable]
# v 0.80 2002.01.22 [beta2]
- Fixed I/O memory leaks.
- Fixed filter memory leaks.
- Fixed ping/pong counting memory leaks (in obsolete code anyway).
- At end of download, also remove "Retry in 10s" entries bearing same name.
- Now makes accurate use of the HTTP "Connection:" header.
- Don't try to open local "config" directory as a file.
- Improved the download selection logic on pushes.
- Be sure to reinstall the SIGPIPE signal handler within the handler
- Fixed bug in header parsing when NUL is the first char on the line.
- Stop filling our Query Hit packets when we reach our own max size limit.
# v 0.80 2002.01.19 [beta]
Summary of changes (user-visible):
- Download queue made persistent: your pending downloads will be saved and
resumed the next time gtk-gnutella is started.
- The download queue will now show the Host information.
- Pushes now work correctly, and gtk-gnutella can also serve push requests to
others, so people behind firewalls may now share as well.
- Search results filtering has been implemented: until now, there was only
the GUI part without any real work done.
- Sorting by host now works on search results.
- Supports the 0.6 handshaking protocol, both for incoming and outgoing
connections. Still accepts 0.4 incoming requests, or issues 0.4 outgoing if
the remote node does not appear to support 0.6.
- Ping/pong traffic is now limited to a few hundred bytes per second on each
connection, lowering the bandwidth usage: you should be able to open more
connections than before for the same bandwidth used.
Detailed changes:
- gtk-gnutella.spec now generated at configure time. [From: Sam Varshavchik]
- LimeWire shut down their router.limewire.com pong cache.
- Trace IP of HTTP requests/replies we send or receive.
- Check for valid index/name combination before checking for upload slots.
- Automatically and silently ignore 0-byte files in search results.
- Silentlently ignore files located in private IPs if we don't send pushes
(this is a temporary hack until someone adds a radio button to achieve this).
- Detect changes in indices for files we already found, and update the
download queue accordingly (patch from Vladimir Klebanov).
- Improved hex dumping routine and use it to dump data on connection problems.
- Don't send user/password to proxy if none was configured
- Assume we're firewalled and advertise so until we get an incoming connection
- Try to parse all extended Query Hit Data (the open part) assuming BS compat.
- Started to reorganize GUI/callbacks in search.c, moving relevant code to
callbacks.c and gui.c. There is still a fair amount of mixing between the
GUI stuff and the program logic, requiring further fine tuning.
- Rewrote NUL detection logic in search query, and now dumps yet unhandled
extra query data.
- Constant refactoring: moved download/upload/socket constants and state
inspection predicates into their respective headers.
- Now scan uploads for timeouts, and added configuration of the various
time limits via two new config variables: "upload_connected_timeout" and
"upload_connecting_timeout".
- Proxy connection errors were not reported (show_error() was not implemented).
- Now parses HTTP headers correctly.
- Handles HTTP "HEAD" requests correctly.
- Handles Gnet handshaking at the 0.6 level. All handshakes are now made at
the 0.6 level, and upon failure, retried at 0.4. As for incoming
connections, both 0.4 and 0.6 are supported.
- Cancelled uploads are now logged with details, since they don't appear
in the GUI currently.
- Mark upload/download as stalled if no I/O within the last minute
- The amount of seconds between two automatic re-queries of the network
now has to be at least of 300 seconds.
- Fixed memory leak in uploads (found by Nate).
- Connection statistics now show two figures, as "x/y": x is the amount of
connected sockets, and y is the amount of attempts made in the background
but not yet fully connected at the application level.
- Node connections statistics are dumped for debugging.
- Downloads now use the new HTTP header parsing code.
- Don't hammer host caches, allow a reasonable delay between two consecutive
connection attemps to the same host.
- Now uses fresh pongs when the saved caught host list has been re-read.
- Send 10 fresh pongs to old 0.4 servents to whom we deny the connection.
- Sent Pushes now use the Gnet connection socket, so they will work when
behind a masquerading+forwarding firewall with only the Gnet port opened.
- Fixed a couple of buglets introduced by the late re-organization of code.
- Added handling of push requests sent by remote servents, i.e gtk-gnutella
will now reply when others request us to push a file to them.
- If search results say remote servent is firewalled, start immediately in
push mode when downloading, provided pushes are authorized.
- Recognizes more vendor codes in QHD (Query Hit Descriptor).
- Implemented LimeWire's ping/pong reducing scheme.
- Created doc/gnutella directory, populated with reference on the recently
implemented algorithms.
- Fixed index-updating bug for downloads in push mode: the mapping was
not updated correctly, resulting in a failed assertion later on.
- Advertise "Pong-Caching: 0.1" in the 0.6 handshake reply.
- Factorized creation of version string, in a "version_string" global
that is now used everywhere the name of the program and its version needs
to be output in a header (User-Agent and Server headers).
- Forgot that search reissue timeout of 0 meant "no reissue". Fixed, and
adapted the label text in front of the entry textarea. Also enlarged
the area a bit. [From: Nate]
- Fixed IP/port setups for socks4 and socks5 proxies: now use network order
instead of native. [From: Robert Bihlmeyer]
- Was not validating config variable `min_dup_ratio'. Adapted its comment,
and made other cosmetic change to the config file output.
- Now initializes version string once and for all, at main() time.
This string is then consistently used in all emitted headers.
- Parses remote "Pong-Caching:" hanshaking header.
- During download requests, force push immediately if the remote end's IP:port
appears to be not connectible, even if the "Push" bit is not set in QHD.
- Created new "Stopped" state, which is used on retry-able error conditions,
such as EOF or "Connection reset by peer" errors. The retry timer was
shortened from 60 to 15 seconds, awaiting to make it configurable.
- Detect and print as such a failed outgoing connection that sent us
connection pongs nonetheless.
- Fixed improper trailer generation in query hits: the last flag byte was
not copied at all.
- Suppressed md5 from the source, it's no longer used.
- Refactoring in routing logic, mainly for push packet handling.
- Push packets are now routed correctly, and no longer widely broadcasted.
- Pushed downloads will abort when the route to the remote servent is lost.
- Forgot to detect TTL=0 pings in our new ping/pong handling logic.
- In case the handshaking fails with a remote strange server, read more data
to be able to trace more of their reply.
- Now parses the Query Hit packets only once, no matter how many searches open.
- Integrated filtering patch [From Robert Bihlmeyer]. You may now apply
filters to your searches.
- Double-clicking on a file in the search window will request downloading
of the selected files. [From Noel T.Nunkovich]
- Removed useless and memory hog host catcher list in the gnutellaNet screen:
saves 2 MB of RAM plus avoids cost of updating it [From Mark Schreiber].
- Be tolerant on servents that do not send a Content-Length but send
a proper Content-Range line instead (which we tolerantly parse as well).
- Accept searches even though we might not be connected to the net yet
[From Mark Schreiber].
- Added Host indication in the download screen [From Mark Schreiber].
- Fixed buglet in has_same_active_download() where "waiting" downloads
were not considered when looking for duplicates, which could lead to
assertion failures for pushes later on.
- When not sharing, don't return query hits [From Mark Schreiber].
- When not sharing, send them a "410 Sharing currently disabled" error.
- Added X-Live-Since: to all our HTTP replies.
- Added download queue persistence.
- Download resuming now checks for proper file via an overlap of 512 bytes.
- Split hostcache into two distinct lists: the reserve, and the list of
nodes we tried and are known to be valid Gnutella servers. In an attempt
to limit the tendency of the hostcache to remove hosts rapidly.
- Will now automatically determine that the forced local IP is obsolete
and change it on the fly, provided we're connecting to modern servents,
which make use of the Remote-IP header during handshaking.
- Compute IP address of public hostcaches once, to avoid many long DNS lookups.
- When low on hosts in cache, collect "semi-pongs" from Query Hits
(an idea from Mike Green). The "low" threshold is 12.5% of maximum.
- Added URL escaping routines.
- Now supports URL-escaped requests, but still sends un-escaped requests to
remote servents.
- Advertise our node address/port using the Node: header on all outgoing
handshakes.
- Minor reformatting of config file comments, and raising of default max
messages to be more tolerent on replies, whilst reducing greatly the max
size of queries to limit potential of abuse.

them)
- Active downloads can now be forced to push mode, moved back to the queue,
or killed (with the output file removed) using right mouse button on them

search results list (GTK doesn't seem to handle well auto sorting)
* v 0.11 2000.04.19
- Sizes of files in the gnutellanet stats, in search results and in downloads
lists are now displayed in B, KB, MB or GB. By the way, the gnutellanet
stats will display the right number of shared bytes...
- Search results can now be sorted by File name, Size, or Speed.
- Buttons 'abort selected', 'resume selected' and 'clear completed' in the
download section should be less randomly active / unactive.
