	*** AOLserver 4.5.1 RELEASED ***

2009-02-01 Gustaf Neumann <neumann@wu-wien.ac.at>

        * nsd/pools.c:

2009-02-01 tag aolserver_v45_r1


2009-01-29 Gustaf Neumann <neumann@wu-wien.ac.at>
        * nsd/pools.c:
          Fixed error message for 'ns_pools set' command

        * nsd/tclcache.c: Fixed behavior such that 'return' in
          'ns_cache eval' works like described in the documentation
          and in the old nscache module. Example:

            ns_cache eval mycache mykey { return [expr {1+1}] }

          Before, 'return' raised a tcl error.

	* doc/ns_cache.n: added documentation of optional 'pattern'
          argument for 'ns_cache names'.

        * Updated Changelog.

2009-01-29 Gustaf Neumann  neumann@wu-wien.ac.at
	* nsssl/ssltcl.c:
	  Remove direct access to interp->result

        * Changelog: Completed Changelog entries from commits after
          the 4.5.0 release.

	* tcl/fastpath.tcl,
	* tcl/file.tcl:
	* tcl/form.tcl:
	* tcl/http.tcl:
	* tcl/nsdb.tcl:
	* tcl/packages.tcl:
	* tcl/sendmail.tcl: Use Tcl 8.4 non-numeric comparison
	  operators where appropriate

2008-12-27 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/nsd.h:
	* nsd/pools.c:
	* nsd/queue.c:
	* tcl/pools.tcl:
          New configure parameter "spread" for ns_pools:    
	
          Background: Requests are distributed to idle threads via
	  CondSignal, which delivers subsequent signals to idle
	  threads in a circular manner (i.e. t1, t2, .. tn, then t1
	  again) determined by the scheduling policy of the operating
	  system. This round robin behavior has the disadvantage that
	  multiple threads terminate about at the same time, based on
	  the maxconnections (or maxconns) value. The idle timeout
	  will never be used on a sufficiently busy server.  

          The mass termination of threads is performance-wise bad,
	  especially when many connections threads are configured,
	  since it is likely that about the same amount of threads
	  will be recreated.  The "spread" parameter introduces a
	  random factor into threadtimeout and maxconnections to avoid
	  these termination cycles.  It adds +/- the specified
	  percentage to maxconnections and threadtimeout (e.g. a
	  spread of 20 means a random value between 0.80 to 1.20 of
	  the specified value of maxconnections and threadtimeout for
	  every connection thread).

2008-12-05 Gustaf Neumann  neumann@wu-wien.ac.at

	* include/ns.h:
	* nsd/limits.c:
	* nsd/pools.c:
	* nsd/server.c:
	* nsext/nsext.c:
	- Provide names for all Ns_Mutex to report meaningful output
	  in aolserver statistics 
        - Set version number to 4.5.0p1 to differentiate from 4.5.0
          unpatched release

2008-10-12 Gustaf Neumann  neumann@wu-wien.ac.at

	* tcl/stats.tcl: Fixed Tcl expressions such they can be
	  compiled into Tcl byte code

2008-09-24 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/queue.c: Fixed boundary condition for starting threads
	  (there was a problem at least with keepwait > 0 and
	  minthreads = 0)

2008-06-20 Gustaf Neumann  neumann@wu-wien.ac.at

	* nscp/nscp.c:
	* nsd/tclloop.c:
	* nsd/tclshare.c:
	* nsproxy/nsproxylib.c:
	  Remove direct access to interp->result

        * Initializing potentially uninitialized variables 
	  in nsproxy/nsproxylib.c:

2008-05-13 Jeff Rogers <dvrsn@diphi.com>

	* configure.in: Add -nostartfiles flag to link line when -shared
 	  is already there.  Without this, build fails against tcl8.5
	* configure: Regenerated

2008-05-10 Daniel P. Stasinski  mooooooo@users.sourceforge.net

	* nsperm/nsperm.c:
	  Fixed bug with netmask parsing 

2008-05-06 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/tclfile.c:
	  Adding missing variable declaration 

2008-04-24 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/tclfile.c:
	  Fix ns_tmpnam for WIN32 environments to return a path in the 
	  TMP directory. 

2008-03-22 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/fd.c: Fix for Mac OS X Leopard: setrlimit with
	  RLIM_INFINITY fails and causes Ns_Log to crash (fix was
	  sketched by David Caruso on the aolserver mailing list on
	  Jan 10, 2008)

2008-01-24 Dossy Shiobara   <dossy@panoptic.com>

	* nscgi/nscgi.c: Added Tcl command "ns_register_cgi" which
	  effectively does the same as "ns_param map" at startup, as
	  it takes the same argument, the map string. Also,
	  REQUEST_URI is now properly set in the env. for CGI
	  executables.

	* nscgi/nscgi.c: Backported nscgi.c rev 1.33 change to
	  aolserver_v40_bp branch.

	* nscgi/nscgi.c: Backported nscgi.c rev 1.34 change to
	  aolserver_v40_bp branch.

	* nscgi/nscgi.c: Oops, REQUEST_URI should have only been the
	  Request-URI, not including the query string.

	* nscgi/nscgi.c:
	  Untabified source, no code changes. 

2007-10-26 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/nsd.h:
	* nsd/pools.c:
	* nsd/queue.c: Keep track of connection thread state. Two new
 	  variables are introduced:

          - starting: keeps the number of currently 
	    starting threads  
          - waiting: the number of threads in the cond waiting state

	  These variables help to get a more precise understanding and
	  allow for better knowledge for thread creation (especially
	  under heavy load)

2007-10-22 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/queue.c: Remove old code for allowing to run more than
	  maxconns requests in one thread (replaced by thread
	  creation); Maintain min-threads threads when threads are
	  exiting.

2007-10-21 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/queue.c:
	  Protect poolptr condition by mutex 

2007-10-20 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/nsd.h:
	* nsd/pools.c:
	* nsd/queue.c:
	  Continuing work on BUG #1615787; instead of performing in
	  boundary situations in the worst case more than the
	  configured maxconns requests, a new connection thread is
	  created automatically after the exit of a thread coming to
	  the end of it work cycle, when jobs are pending and no other
	  thread is able to process these.

	* tcl/util.tcl:
	  using Tcl 8.4 string comparison operators 

2007-10-19 Tom Jackson  rmadilo@users.sourceforge.net

	* nsd/queue.c: Previous versions of AOLserver included the
	  threadpool name in the name of the thread. This commit
	  simply adds back that making it easier to figure out what
	  threadpool was used for a request.

2007-10-19 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/driver.c:
	* nsd/queue.c:

	  Better fix for BUG #1615787 in aolserver 4.5. Although the
	  original fix apparently helped for www.openacs.org, it
	  appears to simply change the timing, but did not fix the
	  problem itself. The problem was that under limited resource
	  configurations (e.g. maxthreads 5, maxconnections 3) and
	  heavy traffic, incoming requests were queued but not
	  processed in new connection threads. The situation was
	  especially bad, when the number of queued requests was
	  larger than maxconnections, since after processing n
	  requests the server was idling with a high number of queued
	  requests. New requests were put to the end of the queue
	  while old (maybe already timed-out) requests are being
	  served. The server appeared to hang.  The current fix cares
	  for queued requests even when maxconns is exceeded. A maybe
	  better approach is to limit the number of queued requests or
	  to restart automatically threads when a thread exists due to
	  maxconns exceeded.

2007-09-29 Gustaf Neumann  neumann@wu-wien.ac.at

	* nsd/conn.c:
	  Extend ns_conn by two commands:  

          - ns_conn channel: Return a Tcl channel from the current
            connection. This channel can be used to talk via Tcl I/O
            to the remote client afterwards. "ns_conn channel" was
            originally written by Zoran.

	  - ns_conn contentsentlength ?number?: Query or set the
	    number of octets sent to the client. This command can be
	    used in connection with "ns_conn channel" to adjust the
	    length entry in a log file in cases, the file was sent via
	    Tcl I/O.

	* tcl/charsets.tcl:
	  fix unbraced expressions and old style comparisons 

2007-08-24 Michael Andrews  michael_andrews@users.sourceforge.net

	* tcl/packages.tcl:
	  Modified log message to better conform to AOLserver standards. 

2007-08-17 Michael Andrews  michael_andrews@users.sourceforge.net

	* tcl/packages.tcl:
	  I changed the way this file works. It now reads the 
	  following from the server config:  
 
         ns_section "ns/server/${serverName}/packages"     
            ns_param library /some/path/here     
            ns_param library /some/path/here     
	    ns_param library /some/path/here     
            ns_param library /some/path/here     
            ns_param require packageNameHere     
	    ns_param require packageNameHere     
            ns_param require packageNameHere  

        All "library" values are added to the ::auto_path All
	"require" values are executed by "ns_ictl package require" The
	"nsinit" and "nspostinit" procs are then run for each package.
	This allows you to specify packages to load at start up.  

2007-08-01 Michael Andrews  michael_andrews@users.sourceforge.net

	* tcl/packages.tcl:
	  - Added License info 
          - changed init commands to all lower case. 

	* tcl/pools.tcl:
	  Added pools.tcl file to set default pool params from server 
	  config. 

	* tcl/pools.tcl:
	  Changed caps in debug notice. 

	* tcl/pools.tcl:
	  Changed debug to notice 

	* tcl/pools.tcl:

	  AOLserver. 

	* examples/config/base.tcl:
	  Changed maxconns to maxconnections to be backward compatible 


2007-06-13 Michael Andrews  michael_andrews@users.sourceforge.net

	* examples/config/base.tcl:
	  Added nscp to the base.tcl (We need to redo the filesystem 
	  layout and configs for the out of the box install). 

2007-05-11 Nathan Folkman <nathan.folkman@gmail.com>

        * nsproxy/nsproxylib.c: Fixed crash bug that occurred when
          trying to create more then one proxy pool. The proxy id now
          takes the form of:

          <pool>-proxy-<number>

2007-05-08 Michael Andrews  michael_andrews@users.sourceforge.net

	* tcl/init.tcl:
	  No longer adds $AOLSERVER/lib to the auto_path if it already 
	  exists. 

	* tcl/packages.tcl:
	  Optimized the code. 

	* tcl/packages.tcl:
	  removed hard return used for testing. 

2007-05-07 Michael Andrews  michael_andrews@users.sourceforge.net

	* tcl/packages.tcl:
	  Added packages.tcl: 
          1) Reads config to set lib paths. 
          2) Reads config to load packages using ns_ictl. 
          3) Runs nsInit procs. 
          4) Runs nsPostInit procs. 

2007-03-12 Nathan Folkman <nathan.folkman@gmail.com>

	* nsd/tclhttp.c: Preliminary support added for getting and
	  retrieving binary data.

2007-01-22 Tom Jackson  rmadilo@users.sourceforge.net

	* nsd/driver.c: [BUG #1615787] Fix deadlock bug when driver
	  thread stalls under specific conditions.  Thanks to Jeff
	  Rogers and Gustaf Neumann.

2006-08-17 Bas Scheffers basscheffers@users.sourceforge.net

	* nsd/tclfile.c: Changed file permissions of mkdir to 777 so
	  it works properly with the system's umask.

2006-08-08 Dossy Shiobara  <dossy@panoptic.com>

	* include/nsattributes.h: Provide default no-op defines for
	  gcc attributes correctly to enable builds on older gcc to
	  work.  Previously, "may_alias" attribute resulted in gcc
	  older than 3.3 to no longer build.  This minor change fixes
	  this.

2006-07-07 Jim Davidson   <jgdavidson@ool.com>

	* include/ns.h:

	* nsd/return.c: Added Ns_RegisterRedirect as a replacement to
	  Ns_RegisterReturn which did not require a virtual server
	  argument as expected.

	* nsd/server.c: Updated to call new Ns_RegisterRedirect,
  	  fixing bug #1518426

	* doc/Ns_ConnReturnStatus.3: Updated to document the new
	  Ns_RegisterRedirect, removing reference to
	  Ns_RegisterReturn.

2006-06-28 Nathan Folkman <nathan.folkman@gmail.com>

	* nsd/adpeval.c: Fixed crash bug in NsAdpLogError() when a
	  NULL adp->framePtr is encountered.

2006-06-02  Jim Davidson <jgdavidson@aol.com>

	* configure:
	* configure.in: Added check for Darwin (OS/X) to disable
	detection of poll which appears broken.  Result is select

        * include/ns.mak.in: Fixed to better support building 64-bit
        on Mac OS X. Assuming Tcl is built with 64-bit extensions
        enabled, it is no longer necessary to explicitly set CC.

        * nszlib/Makefile: Added optional ZLIB environment variable
        to allow user to define location of libz. Default is /usr/lib.

	end of mmap'ed content.

	* nsd/driver.c:
	* nsd/queue.c: Moved free of various conn structures to
	driver where they were allocated to avoid illusion of driver
	constantly leaking memory freed in conn threads.

	* nsd/init.tcl: Init and interp dup code now makes better
	use of ns_ictl.

	* nsd/nsd.h:
	* nsd/server.c: Added support for ns_ictl package and once

            ns_param detailerror true;	 # Include connection detail.
            ns_param displayerror false; # Return error message in page. 

	* nsd/adpeval.c:  Support for error options above plus inhibit
	cacheing of failed execution results (more work required
	here).


2005-08-01  Nathan Folkman <shmooved@aol.com>

        * nsd/adpeval.c:
        * nsd/nsd.h:

	eval in the currently active interp, if any. Also, updated
	code to support running outside a virtual server.

	* nsd/tcljob.c:
	* nsd/tclshare.c:

	* nsd/tclcmds.c: Made ns_atclose an object command.

	* nsthread/tls.c:
	* nsd/Makefile:
	* nsd/tclatclose.c:
	* nsd/tclinit.c: Restructured to be more clear and added
	detailed comments to help describe the Tcl management
	complexity. Also, incorporated code from tclatclose.c and
	moved call to Tcl_FinalizeThread directly into the nsthread
	library.

	* nsthread/pthread.c: Fixed comments.

	* nsd/tclrequest.c:
	* nsd/return.c: Some minor cleanup.


2005-03-04  Nathan Folkman <shmooved@aol.com>

        * nsd/limits.c: Fixed bug where limitsPtr->name was 
        incorrectly being set to NULL. Updated FindLimits() to 
        initialize all values in Limits structure. Renamed keys
        returned by LimitsResult() to distinguish between items 
        which are counts (ntimeout, ndropped, noverflow, etc.) 
        and items which are configuration parameters (maxwait, 
        timeout, maxrun, etc.)


2005-01-18  Nathan Folkman <shmooved@aol.com>

        * nsd/tcljob.c: Minor clean up to "cannot wait on job" error
        message which wasn't correctly implemented.


2005-01-17  Jim Davidson <jgdavidson@aol.com>

	Some work fixing up the new thread pools and limits code.
	Quick background:

	Pools are designed to allow certain requests to be handled
	by specific collections of threads.  This could, for example,
	ensure multiple long running requests don't block other
	short running requests.  Pools are selected based on
	method/url pairs using url-specific data.  By default, all
	requests are handled by a single unlimited "default" pool.
	There is also an "error" pool described below.  You can
	create and configure additional pools with the ns_pools
	command.

	Limits are designed to manage resources before the connection
	is ready to run.  They are also keyed on the method/url
	pair and include such items as max concurrent connections,
	max file upload size, and timeouts for I/O and run wait.
	When limits are exceeded, the driver thread will dispatch
	the connection to the "error" pool to generate a quick
	response.  By default all requests share the same default
	limits.  You can create and configure additional limits
	with the ns_limits command.

	* nsd/nsd.h:
	* nsd/driver.c: Renamed NsGetLimits and NsGetPool to
	NsGetRequestLimits and NsGetConnPool for a bit of clarity.

	* nsd/queue.c: Re-enabled ns_server command, now with
	optional thread arg to specify the thread pool to query
	(default is "default").

	* nsd/pools.c:
	* nsd/limits.c: Cleaned up code and added comments.

	* nsd/encoding.c: Bug fix.


2005-01-17  Jim Davidson <jgdavidson@aol.com>

	* include/ns.h:
	* nsd/connio.c:
	* nsd/conn.c: Added new Ns_ConnSetStatus and Ns_ConnGetStatus
	routines to set/get HTTP response status code to be sent
	in reponses by Ns_ConnFlush.

	* doc/mkLinks:
	* doc/Ns_ConnHeaders.3: Added placeholders for new
	Ns_ConnGetStatus and Ns_ConnSetStatus routines.

	* nsd/nsd.h:
	* nsd/encoding.c: Removed previous private type/encoding
	code now integrated into new public Ns_ConnSetType.

	* nsd/return.c: Updated ReturnCharData to use new Ns_ConnFlush.

	* nsd/server.c: Removed some config code to set encodings
	now determine when needed based on charsets.

	* nsd/form.c: New NsCheckQuery private routine to verify
	query form was decoded with current encoding.

	* nsd/queue.c: Fixed possible race in NsConnArgProc.

	* nsd/adprequest.c:
	* nsd/driver.c: Minor cleanup.


2005-01-15  Jim Davidson <jgdavidson@aol.com>

	Among some general code cleanup, several changes to factor
	out previous ADP-only code for encoding, compressing, and/or
	chunking output via a more general Ns_ConnFlush routine.
	ADP output semantics should now be closer to those of stdio
	including a specific "ns_adp_flush" mechanism to force a
	valid streamed response (likely in HTTP/1.1 "chunked" format)
	during execution as well as a buffer high-water mark which
	will force flushing on overflow (default 1meg).  These
	changes should both be more flexible to use and allow ADP's
	which generate very large results to avoid consuming memory
	waiting to send a single, large response.  Ordinary ADP's
	which generate a normal, relatively small responses, will
	behave as before.

	*  include/ns.h: Added Ns_ConnFlush, Ns_ConnSend, Ns_ConnSetType,
	and Ns_ConnGetType along with some new NS_CONN constaints.

	* nsd/connio.c: Added Ns_ConnFlush which provides a general
	encoding, compressing, chunking response capbility which
	was mostly previous ADP-only code.

	* nsd/conn.c: Added Ns_ConnSetType and Ns_ConnGetType routines.

	* nsd/form.c: Added checks to better catch a change in URL
	encoding.

	* nsd/tclcmds.c:
	* nsd/adpcmds.c: Added ns_adp_ctl, ns_adp_flush, and
	ns_adp_close commands and simplified code with new NsAdpGetBuf
	routine.  Also, use of new Ns_ConnSetType and Ns_ConnGetType
	to factor out previous ADP-only code.

	* nsd/nsd.h: Combined AdpParse and AdpCode structs, several
	new ADP_ and SERV_ flag bits, and several new ADP internal
	routines.

	* nsd/adpeval.c:
	* nsd/adpparse.c: Simplified code by combining AdpParse and
	AdpCode structs and added new AdpTrace facility to monitor
	ADP internals.

	* nsd/adprequest.c: Added NsAdpGetBuf API and factored out
	flush/close code to use new more general Ns_ConnFlush API.

	* nsd/driver.c: Now truncates instead of freeing I/O dstring
	bufs to avoid repeated realloc calls between connections
	(potential source of additional memory growth).

	* nsd/request.c: Added comment for for NsAppendRequest.

	* nsd/return.c:
	* nsd/server.c: Use of new flag bits instead of specific
	bool's and several new config options.  Also, added

	* doc/ns_adp.n:
	* doc/mkLinks:
	* doc/Ns_ConnHeaders.3:
	* doc/Ns_ConnRead.3:
	* doc/Ns_ConnWrite.3: Added placeholders for new ns_adp_close,
	ns_adp_ctl, and ns_adp_flush commands and Ns_ConnFlush,
	Ns_ConnGetType and Ns_ConnSetType routines (unfortunately
	no actual documentation yet).

	* nsd/compress.c:
	* nsd/fastpath.c:
	* nsd/fd.c:
	* nsd/limits.c: nsd/nsmain.c nsd/quotehtml.c: Minor casts
	to silence compiler.


2005-01-03  Zoran Vasiljevic <zv@archiware.com>

	* nsd/tclfile.c: Certain command sequence with [ns_chan] may cause
	  server to crash (see SF BUG #1094480). Fixed now.
	  Also, fixed channel tables cleanup and channel-closing which also
	  cored the server due to better Tcl library checking.

2004-12-06  Dossy Shiobara <dossy@panoptic.com>

	* include/ns.h (1.73), nsd/dns.c (1.12), nsd/tclsock.c (1.21),
	  tests/new/ns_addrbyhost.test (1.2): Implement
	  Ns_GetAllAddrByHost() and [ns_addrbyhost -all].  Closes SF RFE
	  #999452.

2004-12-01  Dossy Shiobara <dossy@panoptic.com>

	* include/ns.h (1.72): Provide NS_VERSION_NUM definition to make
	  conditionalized testing of AOLserver version at build time easy.

2004-11-20  Dossy Shiobara <dossy@panoptic.com>

	* nsd/tclsched.c (1.6): Option parsing needed to be more careful,
	  leading to segfaults when a bad command like [ns_schedule_proc
	  -thread -only] is executed.  Closes SF Bug #1068836.

2004-11-19  Dossy Shiobara <dossy@panoptic.com>

	* configure (1.24), configure.in (1.19): autoconf now detects if
	  libgcc is built shared, in which case LIBS needs -lgcc_s.
	  Without it, the nsd binary will fail to link because of
	  unresolved symbols __umoddi3 and __udivdi3 in nsd/dsprintf.c.

2004-11-19  Dossy Shiobara <dossy@panoptic.com>

	* nsd/Makefile (1.43): Adding -lz to LIBS is now redundant.

2004-11-19  Dossy Shiobara <dossy@panoptic.com>

	* include/nsthread.h (1.28): Need to include <inttypes.h> on some
	  platforms (OS X, Solaris 10) to get C99 "uint32_t" and other
	  types.

2004-11-19  Dossy Shiobara <dossy@panoptic.com>

	* configure (1.23), configure.in (1.18), include/Makefile.global.in

	* nsd/adprequest.c (1.18): Don't send Content-Length if streaming
	  is on.

2004-11-15  Dossy Shiobara <dossy@panoptic.com>

	* nsd/nsmain.c (1.60): AOLserver will now allow setting the fd
	  limit (via "ulimit -Hn", etc.) and only log a warning if it
	  exceeds FD_SETSIZE.  Do this at your own risk, as things which
	  still use select(), i.e., Tcl, are likely to break.

2004-11-05  Dossy Shiobara <dossy@panoptic.com>

	* nsd/sockcallback.c (1.15): Dereferencing cbPtr->nextPtr is
	  dangerous since cbPtr could have been freed.

	* include/nsd.h:
	* nsd/adpcmds.c:
	* nsd/adpeval.c: Updates to new ADP cache capability, changing

	* ns.h:
	* nsd/adpcmds.c:
	* nsd/adpeval.c:
	* nsd/adprequest.c:
	* nsd/nsd.h:

	configuration and/or ns_adp_include -ttl (work in progress).

	* nsd/queue.c:
	* nsd/driver.c:
	* nsd/request.c: Fixes to avoid thread race conditions when
	when using ns_info threads.

2004-10-06  Jim Davidson <jgdavidson@aol.com>

	* include/ns.h:
	* nsd/task.c:
	* nsd/server.c:
	* nsd/tclcmds.c
	* nsd/tclnhttp.c: Added new I/O task API and a new implementation
	of ns_http which uses and has more flexible argument processing.
	A tcl/oldhttp server config option (default on) bypasses the
	new ns_http for the previous implementation based on the sock
	callback API.

	* nsd/nswin32.c:
	* nsd/unix.c:
	* nsd/sock.c: Moved duplicate poll() emulation code to sock.c and
	added the NsPoll() wrapper used in driver.c and task.c.

	* nsd/log.c:
	* nsd/nsmain.c: Ns_Fatal now calls abort() on Ns_Fatal when running
	in debugger mode (i.e., with the -d command line option).

	* nsd/nsd.h: Various updates to support the above additions.

2004-09-30  Dossy Shiobara <dossy@panoptic.com>

	* include/ns.h (1.68), nsd/tclhttp.c (1.21), nsd/sockcallback.c
	  (1.14): Implement Ns_SockCancelCallbackEx() in order to correctly
	  cancel actions in the SockCallbackThread.  Fix for SF Bug
	  #1037196.

2004-09-29  Dossy Shiobara <dossy@panoptic.com>

	* include/ns.h (1.67), nsd/tclhttp.c (1.20), nsd/sockcallback.c
	  (1.13): Fix a thread hang issue when ns_http fails but
	  HttpCancel() never executes because poll() returns revent ==
	  POLLPRI.  Closes SF Bug #1037196.

2004-09-24  Dossy Shiobara <dossy@panoptic.com>

	* include/nsthread.h (1.27): Win32 supports the
	  get{addr,name}info() API, so use it.

2004-09-24  Dossy Shiobara <dossy@panoptic.com>

	* nsd/dns.c (1.11): Small memory leak introduced on platforms w/
	  getaddrinfo.	Closes SF Bug #1033575.

2004-09-22  Dossy Shiobara <dossy@panoptic.com>

	* configure (1.22), configure.in (1.17): get{addr,name}info on
	  Solaris 9 is in -lsocket.

2004-09-21  Dossy Shiobara <dossy@panoptic.com>

	* aclocal.m4 (1.4): Make detection of gethostby{addr,name}_r more
	  robust.  Closes SF Bug #1032231.

2004-09-20  Dossy Shiobara <dossy@panoptic.com>

	* nsd/: nsmain.c (1.58), nsd.h (1.91), unix.c (1.18): Need to set
	  the dumpable flag on Linux in order to get a core file after
	  uid/gid is changed.  Closes SF Bug #1031599.

2004-09-17  Dossy Shiobara <dossy@panoptic.com>

	* nsd/connio.c (1.16): Ns_ConnSend() now bubbles up the error from
	  NsSockSend() on first send, which is what the C API documentation
	  says.  Closes SF Bug #1029512.

2004-09-08  Dossy Shiobara <dossy@panoptic.com>

	* nslog/nslog.html (1.2): Updated nslog module documentation.

	  ::tcl_platform(threaded) at all.

2004-08-20  Jim Davidson <jgdavidson@aol.com>

	* nsd/op.c: Handled error case requests based on overflow flag instead
	of response status.
	* nsd/limits.c: Added some more info returned with the get option.
	* nsd/pools.c: Added "error" pool to handle overflows.
	* nsd/nsd.h:
	* nsd/queue.c:
	* nsd/tclcmds.c:
	* nsd/driver.c: Fixed shutdown bugs and further simplified code.
	Also, added a query mechanism to peek into the state of a driver
	via the new ns_driver command.

2004-08-20  Dossy Shiobara <dossy@panoptic.com>

	* Makefile (1.50), tests/new/all.tcl (1.1), tests/new/harness.tcl
	  (1.2), tests/new/ns_hrefs.test (1.1): Implement automated tests
	  that can be run from a stand-alone tclsh.  New Makefile target
	  added called "test" which runs the tests.

2004-08-17  Dossy Shiobara <dossy@panoptic.com>

	* tcl/fastpath.tcl (1.10): If _ns_dirlist gets an URL without a

	  ns_free() in the wrong place.

2004-08-17  Dossy Shiobara <dossy@panoptic.com>

	* win32/build.tcl (1.6): Parse command line args at start.  Attempt
	  to build "debug" and "release" binaries.  Still needs work.

2004-08-17  Dossy Shiobara <dossy@panoptic.com>

	* nsd/fastpath.c (1.21): Minor change to eliminate Win32
	  compile-time warning.  Closes SF Bug #696806.

2004-08-16  Dossy Shiobara <dossy@panoptic.com>

	* nsd/driver.c (1.34): Win32 platform doesn't support mmap().
	  Maybe should define HAVE_MMAP instead in the future.

2004-08-16  Dossy Shiobara <dossy@panoptic.com>

	* win32/build.tcl (1.5): Add new limits.c and pools.c to nsd.dll

	text/script blocks into a single script block to allow incomplete
	scripts to span multiple blocks (e.g., <% if $cond %> ... <%
	} %>).	The "singlescript" ADP config option enables this on a
	per-virtual server basis.  Also, a "safeeval" config was added
	as well to enable safe evaluation of ADP files as is possible
	with ad-hoc ADP (safe Tcl ignores <% ... %> blocks, allowing
	only pre-configured ADP tags to execute).

2004-08-14  Dossy Shiobara <dossy@panoptic.com>

	* aclocal.m4 (1.3), configure (1.19), nsd/dns.c (1.10): Solaris 7
	  uses gethostbyaddr_r(), and the autoconf and GetHost() versions

	* configure (1.18), configure.in (1.15), aclocal.m4 (1.2),
	  nsd/dns.c (1.9): gethostbyaddr() and gethostbyname() are not
	  thread-safe.	Use the new getaddrinfo() and getnameinfo() API
	  where available, otherwise use gethostbyaddr_r() and
	  gethostbyname_r() if available.  Otherwise, continue to use the
	  non-safe versions but emit a warning at configure time.  Fixes SF
	  Bug #1008721.

2004-08-13  Dossy Shiobara <dossy@panoptic.com>

	* Makefile (1.49): The CVS/ directory was getting included in

2004-08-13  Dossy Shiobara <dossy@panoptic.com>

	* nsd/tclmisc.c (1.31), tests/new/test-ns_hrefs.adp (1.1): ns_hrefs

2004-08-13  Dossy Shiobara <dossy@panoptic.com>

	* Makefile (1.48): New "install-tests-new" target to install new

2004-08-11  Dossy Shiobara <dossy@panoptic.com>

	* nsd/nsconf.c (1.34): Inability to resolve nsconf.hostname to set
	  nsconf.address is no longer fatal, and instead defaults to
	  "0.0.0.0".  Fixes SF Bug #994072.

2004-08-11  Dossy Shiobara <dossy@panoptic.com>

	* nsd/driver.c (1.31): Ensure defMapPtr is initialized.

2004-08-11  Dossy Shiobara <dossy@panoptic.com>

	* nsd/driver.c (1.30): Fixed crash bug when virtual servers are
	  configured, but the "hostname" parameter didn't match any of the
	  virtual servers.  Fixed by introducing new "defaultserver"
	  parameter in the comm. config that must refer to one of the
	  virtual servers being defined.

2004-08-11  Dossy Shiobara <dossy@panoptic.com>

	* sample-config.tcl (1.14): Add "defaultserver" parameter in sample
	  config.

2004-08-10  Dossy Shiobara <dossy@panoptic.com>

	* nsd/driver.c (1.29): Crash due to FreeConn() happening twice,
	  once from DriverThread() and once from SockClose().  Commented
	  out call from SockClose() for now.  Don't decrement
	  limitPtr->nrunning if the connPtr->flags indicated overflow or
	  timeout, since we didn't increment nrunning.	Set responseStatus
	  to 503 so requests actually overflow or timeout again.

2004-08-10  Jim Davidson <JGDavidson@aol.com>

	* nsd/driver.c (1.28): Restructured code (again) to better support
	  overload and timeout conditions (work in progress).

2004-08-10  Jim Davidson <JGDavidson@aol.com>

	* nsd/: nsd.h (1.86), pools.c (1.4), queue.c (1.27): Moved pool
	  selection to pools.c from queue.c and added timeout pool config
	  option.

2004-08-10  Jim Davidson <JGDavidson@aol.com>

	* include/ns.h (1.65): Added conn flags to track overflow and
	  timeout conditions.

	* nsd/tclhttp.c: Add new option to ns_http wait, -servicetime, so
	  you can capture how long the HTTP request took. Backported from

2004-07-18  Dossy Shiobara <dossy@panoptic.com>

	* nsd/: nsd.h (1.83), nsconf.c (1.33), init.c (1.7):
	  Ns_GetAddrByHost() reports errors via Ns_Log(), so calls to it
	  should be done after Ns_Log has been initialized, otherwise very
	  unhelpful error messages are produced.  In particular, this
	  happens when the server is started and the hostname as returned

2004-07-13  Dossy Shiobara <dossy@panoptic.com>

	* nsd/driver.c (1.21): Change to make HTTP request "Host:" header
	  mandatory for HTTP/1.1 connections by returning 400 Bad Request

	  code to use the "hostname" param from the "ns/module/nssock"
	  section to map the default virtual server based on the value

2004-06-22  Zoran Vasiljevic <zv@archiware.com>

	* nsd/tclxkeylist.c: added compatiblity layer for the following
	functions, since it broke some older code:
	    Tcl_GetKeyedListKeys
	    Tcl_GetKeyedListField
	    Tcl_SetKeyedListField
	    Tcl_DeleteKeyedListField

	The compatiblity layer for the string-based Tcl-API is not done.
	I will add this if requested.

	  keyed-list implementation (Patch #812522).

2004-06-19  Zoran Vasiljevic <zv@archiware.com>

	* nsd/tclsock.c: Improved NsTclSockOpenObjCmd() to accept
	  two optional parameters: -localhost and -localport as
	  per patch #815889 from Vlad Seryakov.  The patch itself
	  was used as a starting point but the implementation is
	  different i.e. the command-option parsing is rewritten
	  to be much more tight than in the patch and also in the
	  previous implementation.

2004-06-14 20:28  Dossy Shiobara <dossy@panoptic.com>

	* nsd/connio.c: If nsend == 0, we would never call Ns_WriteConn to
	  flush the queued headers.  This could happen when we're sending
	  zero bytes of data as a response.  This fixes bug #971016 in the
	  case where fastpath.cache=false and fastpath.mmap=false and a
	  zero byte file is requested.

2004-06-14 20:25  Dossy Shiobara <dossy@panoptic.com>

	* nsd/return.c: unnecessary test for data != NULL actually caused
	  part of bug #971016 when fastpath.cache=false and
	  fastpath.mmap=true and the file requested is zero bytes, mmap()
	  returns 0 which gets passed along as data == NULL, causing
	  ReturnCharData() to not flush the queued headers.  removing the
	  if is safe as Ns_WriteConn will simply flush any queued data

2004-06-08  Rob Crittenden <rcrittenden0569@aol.com>

	* Makefile: remove Makefile.module on distclean.
	* include/ns.h, nsd/log.c: Allow users to override logging functions.

	  advance

2004-02-24 07:15  Dossy Shiobara <dossy@panoptic.com>

	* nsd/: nsmain.c, nsd.h, driver.c: fix race condition where
	  DriverThreads are spawned but before they can Ns_SockListenEx,
	  the main thread does its NsClosePreBound and closes the prebound
	  sockets, making them unavailable to the DriverThreads if they
	  require root priv to listen on

	* include/nsthread.h: Bumped up NS_THREAD_NAMESIZE from 32 to 64.
	Mutex names were being truncated, making it impossible to distinguish
	mutexes with longer names when looking at stats.

        * nscgi/nscgi.c: Changed HTTPS env variable to be set to "on" or "off"
	instead of "1" or "0". There doesn't appear to be any standard for
	this, but Apache uses the on/off string in the environment.

2003-12-16  Scott S. Goodwin <scott@scottg.net>

        * nscgi/nscgi.c: Fixed issue with HTTPS environment variable not being
        set, and port not being set to 443 if connection is SSL'd. Manually
        applied these changes from a patch supplied by Vinod Kurup.

2003-11-16  Jim Davidson <jgdavidson@aol.com>

	* include/ns.h: Update version ids, added NS_SOCK_DROP and
	NS_TCL_TRACE constants and pre-queue function definitions.

	* nsd/nsd.h:  Added new "times" struct to Conn for more
	fine-grained timing.  Need to provide options to enable
	these time stamps plus ways to get the data.

	* nsd/driver.c:  Restructured in a few ways:

	1. Each loaded driver now has it's own thread.  This should
	allow some more concurrency (if necessary) and generally
	made the code more manageable.

	2. New pre-queue I/O callback API.  The API will be documented
	with an example HTTP module later.

	3. Conn allocation is handled by the driver threads and
	request buffers have been moved to the Conn from the Sock.

	4. Reads for synchrounous drivers (i.e., SSL) are handled
	by a pool of reader threads instead of by the conn threads.
	The number of threads is set with a "maxreaders" config
	option.  This change should enable both Host: header based
	virtual servers and pre-queue callbacks for SSL connections.

	5. New "maxsocks" config for drivers is now used to manage
	the concurrency limit of the server.  Conn's are now queued
	without limit into the connection pools and the previous
	"maxconns" virtual-server config is ignored.

	* nsd/queue.c: Cleaned up "connsperthread" code and updated
	NsQueueConn to support new driver code.

	* nsd/conn.c:
	* nsd/connio.c:
	* nsd/form.c:
	* nsd/nsd.h:
	* nsd/queue.c:
	* nsd/return.c: Moved connection request buffers from Sock
	to Conn structure.

	* nsd/server.c: Removed startup Conn pre-allocation as Conns
	are now allocated dynamically by the driver.  Also, removed
	the "maxconns" parameter which is no longer used.

	* nssock/nssock.c: Added new "async" option (default on)
	mostly to test new reader thread capabilities of the core
	driver code.

	* nsd/tclinit.c: Added a new generalized Tcl interp tracing
	facility and cleaned up some previous init code.  This
	should make it easier to support standard Tcl extensions
	and will be documented with an example module later.

	* nsd/nsmain.c: Fixed order of driver shutdown wait.

	* nsd/init.c: Fixed order of init calls.

	* nsd/binder.c:
	* nsd/dns.c: Named unnamed mutexes.

	* nsd/tclset.c:
	* nsd/tclsock.c: Removed unused functions.

        * nsd/tclinit.c: Fix the 'oncleanup' option of ns_ictl.
        Modify behavior of Ns_RegisterAtDelete so callbacks are
        run before the interp is destroyed. Expose with new 'ondelete'
        option to ns_ictl.

	* nsd/adprequest.c (): Suppress production of the result data for
	requests with SKIPBODY set.
	* nsd/return.c (ReturnCharData): Allow headers to be returned for
	requests with SKIPBODY; e.g., HEAD requests.

2003-08-21  Zoran Vasiljevic <zoran@archiware.com>

	* nsd/tclfile.c: properly detach and attach the Tcl channel
	out and in the current interpreter.

        * nsd/return.c: Updated to support HTTP/1.1 Transfer Chunk Encoding 
        Headers only.

2003-08-19  Nathan Folkman <shmooved@aol.com>

        * nsd/return.c: Updated to include status code from: 
        RFC 2616 (Hypertext Transfer Protocol -- HTTP/1.1) and
        RFC 2518 (HTTP Extensions for Distributed Authoring -- WEBDAV).

2003-08-12  Elizabeth Thomas <eathomas93@aol.com>

	* nsd/adprequest.c: Don't log ns_adp_abort or ns_adp_break as errors.

	* nsd/conn.c:
        * nslog/nslog.c:
        * include/ns.h:
        * sample-config.tcl: Merge in feature from 3.5 branch (with simpler 
        implementation) for logging of request execution time in access log. 

        To turn on feature add:   

        ns_section "ns/server/${servername}/module/nslog"
           ns_param logreqtime true

        By default the option is disabled. If enabled the connection's
        request time will be appended to the access log before the
        extended headers (if configured).

2003-07-18  Elizabeth Thomas <eathomas93@aol.com>

	* nsd/tclinit.c: Add optional mutex to serialize interp initialization.
        With large init scripts and many threads, there is severe malloc 
        lock contention while tcl evaluates the init script (and populates
        its memory pool). Serializing the initialization reduces the thrashing and 
        results in faster startup.

        * nsd/nsconf.c, nsconf.h, nsd.h: Add config variable 'tclinitlock'
        which activates the above. Defaults to false if not specified.

2003-07-18  Mark Page  <mpagenva@aol.com>

	* nsd/adpeval.c (AdpEval): Check adp.outputPtr validity before
	use.  It can get reset within this adp evaluation loop from
	commands like ns_respond (when it does an internal redirect for
	the file not found case).  In this case, it's appropriate that
	further text from this page code is not appended to the result, as
	other code had determined that the result was complete.

2003-07-12  Zoran Vasiljevic <zoran@archiware.com>

	* nslog/nslog.c: the "X-Forwarded-For" header existence is examined
	when logging the remote user. This allows for logging the real
	remote user wnen it commes from some proxy and/or load balancer.
	Thanks for Gustaf Neumann of XOTcl for the patch. This implements  
	the RFE #770054.

	which would otherwise lead to deadlocks.

2003-06-26  Mark Page  <mpagenva@aol.com>

	* nsd/adpeval.c: Fix problem where ns_adp_include was not propogating
        errors.

2003-06-25  Mark Page  <mpagenva@aol.com>

	* nsd/init.tcl: (ns_eval) Fix thread-safety issue with ns_eval,
	where multiple simultanous usages can clobber a change.
	(_ns_getscript) suppress saving the Tcl global variable 'env' into
	the init script.  Tcl's init takes care of 'env', and including it
	into the init script would cause SetEnvs at interp create that are
	unneeded and undesired.

2003-06-18  Mark Page  <mpagenva@aol.com>

	* nsthread/thread.c (Ns_ThreadCreate): Fix typo in Ns_ThreadCreate
	that was causing it to ignore the stacksize parameter.

	* nsd/init.tcl (_ns_eval): Fix ns_eval to prevent it's bleeding of
	unintended Tcl environment change to the global interp state.

2003-06-06  Zoran Vasiljevic <zoran@archiware.com>

	* nsd/queue.c: fixed "connsperthread" config parameter
	as reported in bug item #749801. Default is set to
	"0" i.e. thread will perform unlimited number of
	connections (never exit) unless it's idle timer
	(if configured) expires. 

2003-05-31  Zoran Vasiljevic <zoran@archiware.com>

	* nsd/config.c: uses Ns_TclDestroyInterp instead of the
	Tcl_DeleteInterp.

	* nsd/nsmain.c:
	* include/Makefile.module.in:

	* configure.in: added --disable-shared so we can now build the
	nsd image statically.

	* nsd/cache.c:

	* doc/Ns_Cache.3: added C-API for Ns_CacheTryLock as in RFE #725704
	
2003-05-30  Mark Page <mpagenva@aol.com>

	* nsd/tclthread.c: fix problem in ns_thread begindetached api.
        This code was failing to create the new thread as detached.
        Also corrected for the Ns_TclDetachedThread C api.  As a
        result of this change, non-detached threads will return their
        TclEval result to Ns_ThreadExit, making it available to a
        thread join.

        make the defaulting semantics work as described.

2003-05-24  Zoran Vasiljevic <zoran@archiware.com>

	* nsd/info.c: added workaround for Tcl_GetMemoryInfo() which
	is not defined in Tcl if somebody undefines USE_THREAD_ALLOC.
	Generally, this call should be avoided altogether.

	* nsd/tclinit.c: added call to Tcl_FinalizeThread() in the
	DeleteInterps() to properly finalize Tcl data on thread exit,
 	thus closing the re-appearing memory leak from V3.3 nsd.

	* nsdb/dbinit.c: fixed hash table initialization in IncrCount
	to TCL_ONE_WORD_KEYS instead of TCL_STRING_KEYS. Credits to
	Jean-Fabrice RABAUTE for the bug report.

2003-05-14  Zoran Vasiljevic <zoran@archiware.com>

	* nsd/tclthread.c: fixed NsTclCondObjCmd to be compatible
	to the 3.x pendant in way it threats the optional timeout
	argument. The 3.x reverted to indefinite (i.e. non-timewait) 
	condvar waits when the optional "timeout" argument was given
        as zero.
	The 4.x version just exited with NS_TIMEOUT (= 0) in such 
 	cases breaking Tcl scripts written for 3.x.
        The corrective measure is to check the passed timeout value
	and if == 0, revert to non-timewait condition waits as the
	3.x does (did).

	* nsd/urlencode.c : (bug fix) urlencode was passing through too
        many characters unencoded.  In particular, the '+' was getting
        passed through, which causes unsymmetric encode/decode since
        '+' in encoded string translates to ' '(space).

	* nsd/tclvar.c (NsTclNsvArrayObjCmd): (bug fix) nsv_array exists
	must return true if an nsv exists, regardless of the number of
	array elements in the nsv.

2003-04-24  Mark Page  <mpagenva@aol.com>

	* nsd/queue.c (ConnRun): Ensure that a Internal Error status is
	returned to the client if an error status is returned from a
	pre-auth filter.  Previously, the connection was simply closed,
	causing difficult to diagnose problems to the client.  Also
	allow traces to run in this situation, so that access logging can
	occur.

          nsd/driver.c:
          nssock/nssock.c:
          nsssl/nsssl.c: Modified Ns_DriverInit. Instead of passing all args
          as parameters to Ns_DriverInit, a comm module must now create an
          Ns_DriverInitData structure and populate it with appropriate values
          (see include/ns.h) and pass that in the call to Ns_DriverInit. The
          Ns_DriverInitData structure is versioned so that we can extend it
          later without affecting other modules.

        *** INCOMPATIBILITY ***

2003-01-28  Nathan Folkman <shmooved@aol.com>

        * nsd/init.tcl: (bug fix) Updated ns_eval command to mark Tcl interp for
        deletion in the case of a TCL_ERROR only. Updated ns_eval to properly
        handle an arbitrarly long number of args. SF bug 675506.

2003-01-24  Elizabeth Thomas <eathomas93@aol.com>

	* include/Makefile.global.in:
        * README: Added $(PURIFY) variable back from 3.4 to facilitate 
        easy purify compile. 

        * configure: Made gcc the default value for $CC instead of cc.

2003-01-23  Elizabeth Thomas <eathomas93@aol.com>

	* Tagged first 4.0 beta: aolserver_v4_r0_beta_1

2003-01-19  Nathan Folkman <shmooved@aol.com>

        * nscp/nscp.c: Cleaned up log messages to be more consistent 
        with other server messages. Moved user name from thread name into
        log notice. Control port logging now disabled by default. Added
        more detailed configuration instructions to sample-config.tcl.

2003-01-18  Zoran Vasiljevic <zoran@archiware.com>
	
	* nsd/init.tcl: Summary of changes:
	  o. added _ns_getpackages to enable "package require".
	  o. fixed various issues in ns_getscript proc related to
	     loading Tcl modules which define namespaced versions
	     of standard Tcl commands.
	  o. fixed ns_eval to return value/error and made compatible
	     with standard Tcl "eval" and AOLserver "ns_eval" from 3.x
	  o. made the entire file little bit more readable.

2003-01-17  Mark Page  <mpagenva@aol.com>

	* nsd/driver.c: Change to SockRead; if request has a
	content-length, null-terminate the content at the specified
	length.  This fixes a problem when some browsers add extra CRLF
	characters beyond the specified content-length on a POST (see this
	by using IE to POST data).

2003-01-16  Elizabeth Thomas <eathomas93@aol.com>

        * nsd/tclmisc.c: Fix WordEndsInSemi so that ns_striphtml correctly
        * handles ampersands that are not followed by a space or semicolon

2002-11-06  Jeremy Collins <jcollins@phpsource.net>

        * nsd/adpparse.c: Changed ParseAtts to make it compatible with
        how parsing works in 3.x.

        * nsd/init.tcl: Fixed namespace bug.

2002-11-05  Jeremy Collins <jcollins@phpsource.net>

        * nsd/adpparse.c: Fixed a bug in Parse.  It was not parsing
        registered tags inside of html tags (ex. <td bgcolor='<tag n='v'>'> )

        * nsd/tclset.c: Fixed a bug with ns_set tcl commands.  
        ns_set idelkey|delkey would not actually delete the key.

2002-11-02  Jim Davidson <jgdavidson@aol.com>

	* nsd/fastpath.c:  Fixed bug with non-server specific cache names.

2002-11-01  Jeremy Collins <jcollins@phpsource.net>

        * nsd/adpparse.c: Fixed a small bug in ParseAtts.  It failed
        to properly parse attribute values with spaces in them.

2002-10-29  Jim Davidson <jgdavidson@aol.com>

	* sample-config.tcl:  Updated with examples for connection
	thread pools and Host header virtual servers.

	* Makefile:  Uses /bin/sh to invoke install-doc.

	* doc/install-doc:  Uses /bin/sh to invoke mkLinks.

	* nsd/form.c:
	* nsd/conn.c:
	* tcl/form.tcl:  Changed "ns_conn files" command to just
	return names of file upload widgets, moving access to other
	meta data to new fileoffset, filelength, and fileheaders
	subcommands. Also, removed the ns_conn string command
	instead of updating.

	* nsd/nsd.h:
	* nsd/driver.c:
	* nsd/nsmain.c:
	* nsd/server.c:
	* nsd/queue.c:  Implemented multiple named thread pools
	for virtual servers and Host header based virtual server
	selection.  See sample-config.tcl for config example.

	* nsd/info.c: Fixed crash bug with NULL server.

	* nsd/tclcmds.c: Removed NsTclConnCmd and NsTclServerCmd
	string commands.


2002-10-14  Jim Davidson <jgdavidson@aol.com>

	* doc/install-doc (new):  New script to install and cross
	link the man pages.

	* Makefile:
	* include/Makefile.module:  Added .PHONY targets and man
	page install target.

	* nsd/conn.c:  Made "ns_conn copy" use Tcl_Write instead
	of Tcl_WriteChars to fix binary file upload bug.

	* nsd/form.c:  Fixed bug where Ns_ConnGetQuery (i.e.,
	ns_conn form) could not handle binary data in multpart file
	uploads.  Also, "ns_conn files" now returns file type.
	
	* nsd/log.c:  Thread ids are now formatted as unsigned
	long.

	* include/ns.h:
	* nsd/config.c:
	* nsd/tclinit.c:
	* nsd/tclcmd.c:
	* nsd/tclsock.c:
	* nsd/main.c:  Added support for libnsd.so to be loaded
	into a standard (thread enabled) tclsh or linked into a
	custom tclsh.  Calling Ns_TclInit from a custom tclsh or
	loading libnsd.so via the load command will add many
	non-server AOLserver commands (e.g., adds ns_set but not
	ns_adp_puts).

	* nsd/server.c:
	* nsd/tcljob.c:  Changed ns_job command to create and queue
	jobs to named queues instead of per-server queues.

	* nsd/tclthread.c:  Added a special Tcl address object type
	to speed access to the object id's.

	* nsd/sched.c:  Threaded events now use a thread pool
	instead of create/delete each time.

	* tcl/form.tcl:  Fixed bug accessing uploaded binary files
	with the ns_getform proc and added ns_getformfile proc to
	address the ".tmpfile" security issue.

	static module support, Ns_TclRegisterAt traces, connection
	I/O functions, loadable comm driver stubs, and more.

	* configure:
	* configure.in:
	* nsd/exec.c:  Removed weird USE_PROCTHREAD code.

	* nsd/init.tcl:  Uses "ns_ictl modules" for module list.

	* nscgi/nscgi.c:  Uses Ns_CopyEnviron, renamed from
	Ns_GetEnvironment.

	* Makefile:  Fixed install bug for install-sh.
	
	* README:  Updated to match AOLserver 3.5.  Various outdated
	docs removed.

	* INSTALL (new):
	* aclocal.m4 (new):
	* configure (new):
	* configure.in (new):
	* include/Makefile.global (removed):
	* include/Mkaefile.global.in (new):
	* include/Makefile.module:  New autoconf-based configuration
	and build.

	* nsd/log.c:
	* nsd/tclenv.c:  Updated to used new autoconf-based compile
	info.

	* nsd/tclatclose.c:
	* nsd/tclvar.c:
	* nsd/tclinit.c:
	* nsd/tcljob.c:
	* nsd/nsd.h:  Moved private struct definitions out of nsd.h
	back to files which depend on them, e.g., struct Filter.

	* nsd/tclatclose.c:
	* nsd/tclinit.c:  Moved Ns_TclRegisterDeferred to tclinit.c.

	* nsd/adpeval.c:
	* nsd/tclsock.c:
	* nsd/tclinitc:  Eliminated NsTclEval in favor of Tcl_EvalEx.

	* nsd/log.c:
	* nsd/nsconf.h:
	* nsd/nsconf.c:  Removed complicated and dubious log
	buffering option.  The new ns_logctl feature can be used
	to batch noisy requests.

	* nsd/tclinit.c:
	* nsd/tclcmds.c:
	* nsd/init.tcl:  Added new ns_init command to replace the
	nsv-based namespace copy/update mechanism.  The init.tcl
	is now called only at startup.

	* conn.c:
	* driver.c:
	* queue.c:
	* nsd.h:  Connection times and timeouts now maintained with
	Ns_Time-based microsecond resolution.

2002-07-14  Jim Davidson <jgdavidson@aol.com>

	* nsd/log.c:
	* nsd/tclcmds.c:  Added the ns_logctl command with options
	to hold, release, flush, etc. the log messages in a thread.

	* nsd/adpcmds.c:
	* nsd/urlopen.c:  Switched to more object-correct
	Tcl_ObjSetVar2.

2002-07-08  Jim Davidson <jgdavidson@aol.com>

	* nsd/tclthread.c:  Cleaned up the object-based commands
	by collecting common argument and new object allocation
	code into single GetArgs function.

2002-07-07  Jim Davidson <jgdavidson@aol.com>

	* nsd/tclvar.c:  Removed string commands because it was
	messy maintaining both.

	* nsd/info.c:
	* nsd/queue.c:
	* nsd/tclcmds.c:
	* nsd/tclset.c:  Added object commands.

	* nsd/tclobj.c:
	* nsd/tclmisc.c:  Updated Ns_Time type code to handle simple
	single-integer times without microsecond resolution.

	* include/ns.h:
	* include/Makefile.global:
	* Makefile:  Updated for AOLserver beta4 release to coincide
	with Tcl beta1 release.

	Otherwise, minor edits to new object commands in several
	places.
	
2002-07-05  Jim Davidson <jgdavidson@aol.com>

	* nsd/nsd.h:
	* nsd/adpcmds.c:
	* nsd/adpeval.c:
	* nsd/adprequest.c:
	* nsd/tclcmds.c:  Updated remaining ADP commands to be
	object-based.  Because the NsInterp->adp struct now uses
	Tcl_Obj's for call frame args, the string commands were
	just dumped.

2002-06-25  Scott S. Goodwin <scott@scottg.net>

	* nsd/tclvar.c:
	* nsd/tclcmds.c: Reimplemented nsv commands as object commands.

2002-06-19  Jim Davidson <jgdavidson@aol.com>

	* include/ns.h:
	* nsd/tclinit.c:  Added new Ns_TclCreateInterp() which
	creates and initializes interps for server and non-server
	interps (e.g., the config interp).  Interps are now
	initialized with a call to Tcl_Init() which enables the
	standard Tcl library procedures (e.g., unknown, http::,
	etc.).

	* nsd/tclthread.c:
	* nsd/tclcmds.c:  Thread and cache related commands no
	longer require a server, exposing them in any interp created
	with Ns_TclCreateInterp.
	
	* nsd/server.c:  NsGetServer handles NULL server.

	In general, the changes above are steps towards making the
	AOLserver API's more useful outside the context of a server.
	The idea is to enable use of libnsd for other applications,
	e.g., shells interps.

2002-06-12  Jeremy Collins <jeremy.collins@phpsource.net>

	* nsd/conn.c:
	* nsd/tclcmds.c: Reimplemented "ns_conn" as an obj based
	command.  In the process I also modified NsTclConnObjCmd to use
	Tcl_GetIndexFromObj.  This should improve performance as well as
	the readability of the code.

	* nsd/auth.c:
	* nsd/form.c:
	* nsd/httptime.c:
	* nsd/log.c:
	* nsd/mimetypes.c:

	* nsd/tclthread.c:
	* nsd/urlencode.c:
	* nsd/urlopen.c: Cleaned up the way we were setting the result
	on tcl errors.

2002-06-12  Jim Davidson <jgdavidson@aol.com>
	
	* include/nsthread.h:
	* nsthread/mutex.c:
	* nsthread/thread.c:
	* nsd/info.c:  Rename Ns_MutexEnum and Ns_ThreadEnum to
	Ns_MutexList and Ns_ThreadList to not conflict with pre-4.0
	definitions of removed functions.

	* nsthread/Makefile
	* nsthread/nshtreadtest.c (new file):  Added simple program
	to test thread interface.

	* nsthread/thread.h:
	* nsthread/cslock.c:
	* nsthread/rwlock.c:  Added new NsMutexInitNext function
	to consistantly name mutexes in internal objects.

	* nsthread/sema.c:  Restored AOLserver 3.x implementation
	using Ns_Mutex and Ns_Cond objects.  The API's in <semaphore.h>
	were not implemented on OS/X.

2002-06-10  Jim Davidson <jgdavidson@aol.com>

	* include/Makefile.global:
	* include/Makefile.module:  Added support for dynamic
	library init procs set via the LIBINIT make variable.

2002-06-08  Jim Davidson <jgdavidson@aol.com>

	* include/Makefile.global
	* include/Makefile.module:  Support for building programs
	along with dynamic libraries and modules.  Also, fixed bug
	setting -install_name on OS/X.

	* nsd/Makefile:  Use of updated Makefile.module and include
	osxcompat.o on OS/X.

	* nsd/nsd.h:
	* nsd/osxcompat.h:
	* nsd/osxcompat.c:  Compat functions moved from ../nsosx.

	* nsosx/README (removed):
	* nsosx/Makefile (removed):
	* nsosx/nsosx.c (removed):  Tcl no longer requires any
	compat functions, remainder moved into nsd.

	Otherwise, minor tweaks throughout to silence compiler
	warnings.

2002-06-05  Jim Davidson <jgdavidson@aol.com>

	* Makefile:
	* include/Makefile.global:  Added tclmemdbg flag to compile
	Tcl and AOLserver with TCL_MEM_DEBUG option.

	* nsd/unix.o:
	* nsosx/README (new file):
	* nsosx/Makefile (new file):

	* nsd/adpparse.c:
	* nsd/adpcmds.c:
	* nsd/adpeval.c:  Added support for new ns_adp_safeeval
	and ns_adp_registerproc commands. Also, registered tags
	can now be modified after startup.

	* include/Makefile.module:  Updated to allow building of
	dynamic library of public routines to go with dynamic
	module, e.g., libnsdb.so with nsdb.so.

	* nsext/Makefile:
	* nspd/Makefile:
	* nspd/msg.c (removed):
	* nsext/msg.c (moved from nspd):  Moved Ns_Ext API from
	libnspd.a static library to libnsext.so dynamic library as
	it's used by both nsext.so and proxy drivers.

	* nsdb/Makefile:
	* nsdb/nsext.c (new file):  Moved public API for nsdb out
	of nsdb.so module and into libnsdb.so dynamic library.

2002-05-15  Jim Davidson <jgdavidson@aol.com>

	* Makefile:
	* include/Makefile.global:
	* tcl8.3.4 (removed):  As of Tcl version 8.4., no modifications
	to the Tcl sources are required for AOLserver.  Therefore,
	the hacked 8.3.4 sources have been removed.  Going forward
	you'll need to checkout the Tcl source from Sourceforge
	into the directory specified in include/Makefile.global
	(currently ../tcl8.4).  The top level Makefile includes
	the "tcl-checkout" and "tcl-update" targets which should
	help.

	* nsdb/dbutil.c (new):
	* include/nsdb.h (new):  Moved the NsDb interface from core
	to new nsdb module.  Simply loading nsdb.so should work as
	before.  Goal is to enable full replacement of NsDb in the
	future.

	* nsd/nsd.h
	* nsd/unix.c:
	* tcl8.3.4/unix/tclLoadDyld.c: Hacks for routines missing
	from OS/X. The implementation of sigwait() is not strictly
	correct but appears good enough for AOLserver's use.

	* Makefile:
	* nsd/Makefile:
	* nsmain/Makefile:
	* include/Makefile.global:
	* include/Makefile.module:
	* include/Makefile.library (removed): Updates for linking
	modules against the nsd shared library and for library
	filenames which don't end in .so.

	* nsd/Makefile:
	* nsmain/*:
	* sample-config.tcl:
	* tcl2ini.tcl:
	* ini2tcl.tcl:
	* Makefile: Moved build and install of nsd and init.tcl
	into nsd directory and install of sample config to top

	via ns_thread wait.

2001-12-20  Scott S. Goodwin  <scott@scottg.net>

	* include/Makefile.library: Changed RFLAG to RPATH, and took out
	$(AOLSERVER)/lib:
	
	  $(LDSO) -o $(LIB) $(OBJS) $(LIBS) $(RFLAG) $(AOLSERVER)/lib

	now reads:
	
	  $(LDSO) -o $(LIB) $(OBJS) $(LIBS) $(RPATH)

	which is what I think was intended. Still have the problem
	that $(AOLSERVER)/lib must already exist.

2001-11-05  Jim Davidson <jgdavidson@aol.com>

	* Removed support for Win32, removing both the build/test
	environment and updating the code to be standard Unix style.
	Among other style changes such as changing SOCKET's to
	simple Unix style int's, the short lived Ns_Buf structure
	was also eliminated in favor of the Unix standard struct
	iovec.

	* Removed support for older non-pthread Unix platforms such
	as HP/10 and SGI native.

	* Updated Tcl to version to Tcl 8.3.4, replacing tclAlloc.c
	with a modified version of what was libnsthread's fast pool
	allocator including support for fast direct Tcl_Obj
	allocation.  Also added a few functions to tclUnixThrd.c
	for thread safety (e.g., readdir_r and localtime_r support)
	and fixed up tcl.m4 for better FreeBSD 4.4 and Solaris
	thread builds.

	* ns_malloc, Ns_ThreadMalloc, and Ns_PoolAlloc all now
	simply call Tcl_Alloc which is always enabled. The previous
	-z (enable) and -p (disable) command line flags are ignored.

	* Integrated remainder of libnsthread, now standard pthreads
	and compatible with Tcl pthread code, into libnsd.so.

	* Updated libnsd.so to use poll() instead of select() where
	possible.

	* Removed the code which would attempt to determine when
	the sock callbacks and scheduler were idle before completing
	startup.  The code was overly complex and not strictly
	correct.

	* Removed the -k and -K shutdown/restart options which was
	not entirely safe.

	* Removed the child-process privleged port Ns_SockListen
	code in nsd/binder.c.  Binding privleged ports (e.g., port
	80) now requires the -b or -B command line methods introduced
	in 3.4, e.g., "nsd -ft nsd.tcl -b myhost:80".  The binder
	code, while clever, was a potential security risk.

	* Cleaned up some lingering sloppy uses of Ns_ConfigGet
	and other older macros.  Old macro and function definitions
	can be disabled by defining NS_NOCOMPAT as is done when
	compiling the core server and modules.

	* Incremented version to 4.0b2.

2001-08-29  Scott S. Goodwin  <scott@scottg.net>

	* https.tcl: made fixes to ns_httppost per Rick Lansky at
	bom.com. He also suggested I allow the Content-type to be
	passed in as a parameter, so I've added that too.

2001-08-27  Scott S. Goodwin  <scott@scottg.net>

	* https.tcl: added ns_httppost, that is called with url,
	rqset, qsset and timeout. The qsset is an ns_set with
	key/values that will be turned into user=scottg&pass=1234,
	for example, and passed as content in the POST.

2001-08-17  Scott S. Goodwin  <scott@scottg.net>

	* tcl/http.tcl: moved rqset to be the last arg passed to
	ns_httpget so it wouldn't break existing code. I should
	have done it that way in the first place.

2001-08-15  Scott S. Goodwin  <scott@scottg.net>

	* tcl/http.tcl: add the rqset param as the second argument to
	ns_httpget, which in turn calls ns_httpsopen and passes the rqset
	to it. The change is for consistency so that you can use cookies
	with ns_httpget as well.

2001-07-16  Scott S. Goodwin  <scott@scottg.net>

	* tcl/http.tcl: you can now do ns_httpopen GET /index.html;
	the script will automatically prepend http://hostname:port/
	to the url.

2001-06-30  Dossy Shiobara  <scott@scottg.net>

	* nsd/conn.c, tests/api/ns_conn.adp: fixed ns_conn
	outputheaders as per bug #433676 submitted by Yon Derek
	(yond).

2001-05-22  Scott S. Goodwin  <scott@scottg.net>

	* nsd/conn.c: changed Ns_ConnDriverContext in 4.x to return
	the actual conn-specific, module-specific context back,
	which is how it works in 3.x. For some reason this API call
	was changed to always return NULL, but nsopenssl and
	potentially other comm drivers need to get their conn-specific
	info back.

2001-04-25  Dossy Shiobara  <dossy@panoptic.com>

	* Implemented [ns_localtime ?tz?] as per "[ #418890 ]
	ns_localtime should accept timezone".

2001-03-15  Dossy Shiobara  <dossy@panoptic.com>

	* include/Makefile.win32 win32/*/Makefile: initial attempts
	at Makefiles suitable for NMAKE for building on Win32

	* include/ns.h: define typedef __int64 INT64 for Win32

2001-03-12  Scott S. Goodwin  <scott@scottg.net>

	* nsmain.c: Segmentation fault when using -g <group> flag:
	line 294 should read Ns_GetGid(garg) instead of Ns_GetGid(optarg).

2001-03-12 Jim Davidson

	Initial checkin of AOLserver 4.0 (beta), now supporting
	vitual servers and (finally) removing supporting for Tcl
	7.6.
	
2001-03-08  Kris Rehberg

	*** AOLserver 3.3 RELEASED ***

2001-03-08 Jim Davidson

	* Added NsTclFinalizeThread() at end of Tcl TLS cleanup to
	finalize Tcl 8.x thread data.  This fix was the last hurdle
	for finalizing nsd8x.

2001-01-31  Kris Rehberg 

	* Makefile (MODULES): nsunix, nsvhr, and nsodbc moved to
	the Module Collection.

2001-01-16  Jim Davidson

	* Cleaned up sloppy use of the nsServer global wherever
	it's used.

2001-01-04  Kris Rehberg 

	* nsd/tclmisc.c: Ticket 13090.  ns_striphtml crashing-bug
	in nsd8x fixed.

2000-12-14  Kris Rehberg 

	* tcl/http.tcl: Corrected typo _ns_ns_http_readable.

	* nsd/dstring.c (Ns_DStringPrintf): Ticket 12765.
	Ns_DStringPrintf uses vsnprintf instead of vsprintf with
	specified buffer size.  Thanks to "??".

	* nsd/return.c (Ns_ConnConstructHeaders): Ticket 12764.
	If-Modified-Since (304) works with keepalive now. Thanks
	to Jim "??".

2000-12-13  Kris Rehberg 

	* include/Makefile.global: Builds with architecture-specific
	optimization options. Auto-detects architecture for most
	platforms.  Auto-select compiler and Purify usage from
	command line, e.g.:
	gmake nativeme=1   (all non-free Unix)
	gmake gccme=1      (some non-free Unix) gmake
	PURIFY=/path/to/purify/executable  (Solaris and Irix only)

	* nssock/Makefile*: now installs The Right Things in The
	Right Places.

	* nsd/Makefile: nsd8x is the default AOLserver now (nsd
	symlinks to nsd8x).

	* nsd/sample-config.tcl: Added some tuning parameters for
	easy reference.

2000-12-12  Kris Rehberg 

	* nsvhr/nsvhr.c (UDSProxy): More type changes.

	* nslog/nslog.c (Ns_ModuleInit): pointer-to-function casted.

	* nscp/nscp.c (GetLine): buf changed to char *; casted
	AcceptProc.
	
2000-12-12  Jim Davidson

	* nssock/sock.cpp: Fixed multiple-load problems, added
	sndbuf, rcvbuf, sendwait, and recvwait options. Added
	configurable backlog via Ns_SockListenEx. Fixed compile
	bugs for ssl. Restructured the socket module to wait in
	server busy situations instead of sending the server busy
	message.  Also, moved the graceful close burden to the
	SockThread from the connection thread.

	* thread/win32.cpp: Moved WinThread allocation to DllMain,
	eliminating GetWinThread function. Also, disabled thread
	cleanup for final thread to avoid any TLS cleanup callbacks
	attempting to invoke code in unloaded libraries like Tcl.
	Removed call to NsInitThread no longer needed. Switched to
	rolling condition broadcast wakeup as in the sproc code.
	More fixes for new Thread context model.
	
	* thread/tls.c: Changed NsLock API's to return 1/0 instead
	of NS_OK/NS_TIMEOUT and more use of Ns_MasterLock to keep
	things simple.

	* thread/thread.c: Changed thread enum to return Ns_Thread,
	not Ns_Thread pointer which didn't make much sense.  Updated
	"ns_info pools" command to reflect change. Fixed bugs with
	Ns_ThreadEnum and pool counters. Update of the Ns_Pool API
	to support more stats gathering available via new Ns_PoolStats
	API. Remove Thread->etime and NsPool API's. Moved sprintf
	of default thread name from NsThreadMain to NsInitThread
	under protection of threads lock. Added comment for
	NsInitThread. More fixes for new Thread context model.
	Updated sproc.cpp code for new Thread management and removed
	the wait for thread startup which shouldn't be needed.

	* thread/test.c: Cleaned up code a bit to quiet compiler.
	Better test for PTHREAD_TEST.  Fixed undefined var bug for
	sproc.  Added some comments, a native pthread test, and a
	recursive stack checker.

	* thread/tcl8x.c: Added Tcl_JoinThread for benefit of
	Tcl8.4.

	* thread/sproc.cpp: Changed NsLock API's to return 1/0
	instead of NS_OK/NS_TIMEOUT and more use of Ns_MasterLock
	to keep things simple. Fixed some comment bugs, update
	thrPtr->tid after fork. Added call the NsInitThread. Updated
	sproc.cpp code for new Thread management and removed the
	wait for thread startup which shouldn't be needed.

	* thread/pthread.cpp: Changed NsLock API's to return 1/0
	instead of NS_OK/NS_TIMEOUT and more use of Ns_MasterLock
	to keep things simple. Fixed bug of not setting the tid
	correctly. Added call the NsInitThread.

	* thread/pool.c: Added Ns_PoolEnum to get at pool stats as
	with mutexes and threads, removing the old Ns_PoolStats
	API's and updating the "ns_info pools" command. Fixed bugs
	with Ns_ThreadEnum and pool counters. Update of the Ns_Pool
	API to support more stats gathering available via new
	Ns_PoolStats API. Removed <mutex.h> for sgi which shouldn't
	have been there. Removed the sbrk() code for now, was
	crashing SGI (probably not thread safe). Use sbrk() on Unix
	instead of malloc to avoid any malloc overhead or contention.
	Reduced the zippy allocator page size to 16k from 64k.

	* thread/pool.c, thread.c, sproc.cpp: Re-structured management
	of the Thread context to better support threads created
	without Ns_ThreadCreate (e.g., Java VM threads).
	
	* thread/mutex.c: Changed NsLock API's to return 1/0 instead
	of NS_OK/NS_TIMEOUT and more use of Ns_MasterLock to keep
	things simple.

	* thread/cs.c, memory.c, mutex.c, pool.c, pthread.cpp,
	reentrant.c, rwlock.c, sema.c, sproc.cpp, tcl8x.c, test.c,
	thread.c, win32.cpp: Restructured the thread interfaces,
	moving the master lock to the platform interface code,
	integrating the zippy allocator with Ns_Pool/Ns_ThreadAlloc
	and use of a new simple direct allocator for all thread
	objects.

	* win32/nsthread/nsthread.dsp: Removed master.c and
	oldpools.c.

	* nsd/unix.c: Made ns_eval command disabled by default to
	avoid using SIGUSR2.

	* nsd/tclthread.c: Changed SETOBJ macro to SetObj function
	which no longer sprintf's directly into interp->result.

	* nsd/tclmisc.c: Added Ns_PoolEnum to get at pool stats as
	with mutexes and threads, removing the old Ns_PoolStats
	API's and updating the "ns_info pools" command. Changed
	thread enum to return Ns_Thread, not Ns_Thread pointer
	which didn't make much sense.  Updated "ns_info pools"
	command to reflect change.  Added more info for "ns_info
	pools".  Added "ns_info pools" command to dump memory pool
	stats.
	
	* nsd/tclinit.c: Added nsconf.quiet and nsconf.startuptimeout.
	Made ns_eval command disabled by default to avoid using
	SIGUSR2.  Added nsConfQuiet flag to quiet down the startup
	messages with the -q flag.

	* nsd/sock.c: Added Ns_SockListenEx.

	* nsd/serv.c: Ensured the conn thread name was set first.
	Added Ns_RegisterAtReady callbacks for indicating server
	no longer busy.

	* nsd/sched.c, nsmain.c, serv.c, sockcallback.c: Added code
	to wait for conn thread, sock callback, and sched idle at
	startup to help alleviate code start problems.

	* nsd/nsmain.c: Shuffled initialization to ensure command
	line args are read before calling any Ns API's, ensuring
	zippy malloc can be set if needed.

	* nsd/nsconf.c: Added nsconf.quiet and nsconf.startuptimeout.
	Made ns_eval command disabled by default to avoid using
	SIGUSR2.

	* nsd/dstring.c: Remove unused vars.  Uses ns_realloc to
	grow strings and maintains dstring stack in the staticSpace
	instead of the *addr pointer for compatibility with Tcl
	dstrings.

	* nsd/callbacks.c: Added Ns_RegisterAtReady callbacks for
	indicating server no longer busy.

	* nsd/binder.c: Added Ns_SockListenEx.

2000-12-12  Kris Rehberg 
	
	* nsvhr/nsvhr.c (VHRProc): Matches hostnames regardless of
	case.

	* nssock: Supports Rainbow CryptoSwift SSL accelerators
	(compile-time option; requires the Swift SDK from
	http://www.rainbow.com/).

	* nsd/nsmain.c (Ns_Main): Changed order of some config
	default initialization.  Config options cleaned up a lot.
	Usage message very less glib.  SUNWspro dumped core on
	usage message due to nsconf.argv0 quigglyness.
	
2000-10-20  Kris Rehberg 

	*** AOLserver 3.2 RELEASED ***

2000-10-20  Jim Davidson

	* win/tclWinSock.c: Fixed deadlock in sockets init code.

	* nsd/nswin32.c: Fixed service install code to allow long
	pathnames with spaces.  Added/use ns_pipe which set's
	close-on-exec like ns_sockpair.
	

2000-10-17  Kris Rehberg 

	* nssock/sock.cpp: extra padding on Server Busy message to
	defeat MSIE friendly error messages.

	* nsd/nsconf.h: All configuration option defaults have been
	moved to nsconf.h as #defines.

	* Makefile (install): Tcl library for nsd8x is now installed
	into $(PREFIX)/lib/tcl8.3.

	* tcl/http.tcl (ns_httpopen): Host:port is now sent to
	remote host if != 80.  Suggested by Jerry Asher.

	* tcl/fastpath.tcl (_ns_dirlist): All kinds of Win32
	pathnames should now be working.  Thanks to Eric Klein.

	* nsd/return.c (Ns_ConnReturnNotice): New options
	"errorminsize", to pad error messages to defeat MSIE friendly
	errors (fix suggested by ArsDigita) and "noticedetail" to
	return more detailed information on notice pages.

	* nslog/nslog.c: suppressquery option added to suppress
	logging of query data.

	* nslog/nslog.c: LogExtendedHEaders option added.  Contributed
	by ArsDigita.


	* nsd/tclfile.c: Input string to mktemp is copied, because
	mktemp edits the string in-place and that's generally a
	bad thing to do with argv's.  Contributed by ArsDigita.

	* nsd/tclnsshare.cpp (ShareTraceProc): Patch to tclnsshare.cpp
	to avoid race conditions if the shared value is a list.
	Contributed by ArsDigita.

	* tcl/http.tcl (ns_httpopen): CRLF now returned in ns_httpopen.
	Contributed by ArsDigita.

	* tcl8.3.2/generic/tclCmdIL.c: Nonsense case of lsorting
	a list with length <= 0 caused a memory leak.  Fixed.
	Contributed by ArsDigita.
	
	* nsd/adpfancy.c: We now use the Arsdigita version of
	adpfancy.  Contributed by ArsDigita.
	
	* nsd/adp.c: Sundry ArsDigita changes.

2000-10-16  Kris Rehberg 

	* tcl/init.tcl:  Initialize errorCode and errorInfo like
	tclsh does.  From ArsDigita.

	* nsd/nsd.h, nsd/tclcmds.c, nsd/tclvar.c: nsv_names Tcl
	command lists names of nsv's in memory.

	* tcl8.3.2: The complete Tcl 8.x distributions are now
	included.  They aren't installed with AOLserver's "gmake
	install", but you can install them manually if you want to
	use them for the i18n encodings and stuff like that.  It
	will install into the "lib/tcl8.3" directory of the binary
	distribution with AOLserver 3.3 and later.

	* nsd/nsmain.c (Ns_Main): Had to move Ns_ThreadSetName
	below the stdin/stdout/stderr reassignment to fix a fd
	problem with running nsd on Irix in "installed" or "daemon"
	mode that would prevent the server from starting up.  Sigh.
	(Ns_Main): Took out little note about -k|-K being deprecated.

2000-10-13  Kris Rehberg 

	* nsd/nsmain.c (Ns_Main): gid of the specified user is set even if
	it's not specified.
	(UsageError): -K and -k give a "deprecated" warning.
	(Ns_Main): -f gives a "deprecated" warning.

	* nsd/binder.c (PreBind): Didn't really tell us if it was
	successful at pre-binding.  Helpful to know if you're
	wondering what happened to that port you wanted to pre-bind.
	(Binder): backlog variables (2) initialized to nsconf.backlog.

	* nssock/sock.cpp, nsd/return.c: Made an attempt at
	standardizing the error codes and error page content.
	
2000-10-13  Jim Davidson
	
	* sproc.cpp: Fixed Wakeup() error message and update child's
	sproc pid after fork.

	* nsd/random.c: Put back log message when generating seeds.

	* nsd/nsconf.c: Fixed memory overwrite bug in stats and
	increased the default buffer value.

	* nsd/keepalive.c: Fixed array overwrite with maxkeep=0
	bug.  Contributed by ArsDigita.
	
	* nsd/tclkeylist.c: A more modern version added that's
	compatible with Tcl 8.3.2 (nsd8x).

	* nsd/stamp.c: Forces the build date reported by AOLserver
	to be absolutely the last possible moment before the link
	step happens, not just the last time nsmain.c was built.

	* nsd/binder.c: New option "-b" to prebind ports as root
	(but not listen on them).  This allows AOLserver to start
	up on MacOS X on ports 80 and 443 like this:  "nsd ..blah..
	-b 10.0.0.1:80".

	* nssock/: Building nsssl is much less of a debacle and
	doesn't rebuild itself three times anymore.

	* various: fork() calls in all kinds of code were changed
	to use ns_fork.  ns_fork now lives in the thread library
	(thread/ directory).

	* tcl8.3.2/generic/tclIO.c: Fixed memory leak that leaks
	around 112 bytes each time a file descriptor is closed.
	Thanks to Rob Mayoff for finding this and proposing a
	solution.

2000-10-09  Kris Rehberg 

	* sample-config.tcl: nsd.tcl is now sample-config.tcl so
	that existing users can look at the new reference configuration.

	* nsd/nsmain.c (Ns_InfoNameOfExecutable): new function just
	returns nsconf.nsd which is determined elsewhere.

	* nscp/nscp.c (Login): Tells you lots of harmless info
	about the machine once you log in.  Also, nscp does not
	run unless configuration is explicitly set

	* nsd/nsmain.c: Some typo or other.

	* General: Files were re-arranged and some were renamed.
	The sample SSL key/cert files are sample-certfile,
	sample-keyfile.  The nsd.tcl is now called sample-config.tcl
	(so that existing installations always have a current
	reference copy of the configuration).  Other minor changes.

	* tests/:  Moved from its hiding place in scripts/test.
	Install them with "gmake install-tests".

	* nsd/tclxkeylist.c, nsd/tclcmds.c, nsd/Makefile: Re-added
	TclX keyl* commands that were in AOLserver 2.x.  These are
	inferior to ns_set which is why they were left out in the
	first place.

2000-10-04  Jim Davidson

	* binder.c: Set close-on-exec on received fd from binder.
	
	* sock.c: Removed cthread errno API's, Mac OS X now has
	thread-safe errno.

	* nsd/nsmain.c, include/Makefile.global, nsd/nsthread.h,
	nspd/main.c, nsunix/nsunix.c, nsvhr/nsvhr.c, thread/Makefile,
	thread/osthread, thread/reentrant.c, thread/signal.c:
	Updates for Mac OS X.  Use MACOSX instead of APPLE; use
	HAVE_BSDSETPGRP, HAVE_CMMSG, use pthreads instead of
	cthreads.
	
	* nssock/sock.c: Removed setting bufsize to uninitialized
	value on ssl.

	* include/ns.h: Removed Ns_CacheTimedGetValue which was an
	odd interface not used anywhere.
	
	* nsd/nsd.h: Update to version 3.11.
	
	* tcl/namespace.tcl: Added namespace export to init script.
	
	* thread/pthread.cpp: Stopped using pthread_once as it
	appears to require a lock.
	
2000-10-04  Kris Rehberg 

	* win32/nsssl/nsssl.dsp: nsssl project for win32.

	* win32/aolserver.dsw: main installation keeps DLL's as
	DLL's now.

	* scripts/nsd.tcl: shared library extension is now
	platform-dependent

	* nssock/ssltcl.c: Changed name of ReadFile adn WriteFile
	to avoid Win32 naming conflicts.
	
2000-09-28  Kris Rehberg 

	* scripts/tests/nstelemetry.adp: added "Expires: now" header
	to ensure it gets run each time it's visitted.

	* nsd/serv.c (NsConnArgProc): Race condition when threads
	exit while [ns_info threads] is run; arg can be NULL.  Seen
	mostly by people who regularly visit nstelemetry.adp.
	(AppendConn): same thing but with connPtr.  This may be a
	losing battle.  It appears to work on a busy Irix server,
	so I'm declaring victory for now.

2000-09-28  Jim Davidson
	
	* nssock/sock.c: Fixed bufferred read code in SockRead,
	resulting in a big performance boost and system load
	reduction.  Special thanks to Zachary Girouard.

2000-09-05  Kris Rehberg 

	*** AOLserver 3.1 Released *** 

2000-09-05  (various: Jerry Asher, Jim Davidson, "Dossy," Curtis Galloway,
	Scott S. Goodwin, Rob Mayoff, Kris Rehberg)

	* thread/win32.cpp: Sets thread stack size as on other
	platforms.

	* thread/thread.c: NULL out thread arg at exit to avoid
	Ns_ThreadEnum checking arg info for possibly deallocated
	context as seen in ns_info threads.  Also, moved read of
	firstPtr in Ns_ThreadEnum inside lock.  Added Ns_ThreadCreate2
	in thread.c needed for upgrade to Tcl 8.3.1 in tcl8x.c
	
	* thread/pthread.cpp: ETIME bug work around not causes
	wakeup in Ns_CondWait and Ns_CondTimeWait instead of waiting
	again.  This is more conservative and should avoid problems
	some have had with threads missing wakeup.

	* thread/pool.c: Added a simple 1-byte range check to -z
	allocator.

	* thread/Makefile: Added dependency for osthread.o to
	Makefile.

	* tcl/namespace.tcl: Added namespace export to init script.

	* nsvhr/nsvhr.c: Switched to Ns_WriteConn in TimedSockDump
	to ensure all data was sent.

	* nssock(nsssl): SSL module includes a fake 40-bit/512-bit
	export-grade SSL keyfile.pem and certfile.pem for immediate
	use on installation.  Adjusted for use with BSAFE 4 and 5.

	* nspd: Library now installed to binary distribution.

	* nsd/tclsock.c: Fixed crash bug in error message in
	ns_socknread.

	* nsd/tclcmds.c: Added ns_adp_registertag command as
	documented.
	
	* nsd/serv.c: Added missing break for unauthorized case in
	ConnRun.

	* nsd/random.c: Fixed deadlock between Ns_DRand/Ns_GenSeeds.
	
	* nsd/nsmain.c: Fixed some message formatting problems.

	* nsd/mimetypes.c: Added .png type, "image/png".
	
	* nsd/dbtcl.c: Removed unused variables in GetCsvCmd.  Use
	a dstring to create the column list instead of incrementally
	setting the output variable with Tcl_SetVar.  This was
	necessary to avoid conflicting definitions of the needed
	TCL_ flags between 7.6 and 8.x.

	* nsd/dbinit.c: MOdified current per-thread handle count
	to use a single TLS slot instead of a slot per pool.
	
	* nsd/tclinit.c,adp.c,conn.c: The use of thread-local
	storage (Tls) is now self-initializing in the conn, ADP,
	Tcl, etc.  This allows ns_conn commands to be used outside
	a connection thread as well as other uses of Tls where it
	may not be ready for use.

	* nscp/nscp.c: Password non-echo code confuses Win32 and
	some free Unix telnet clients so it has been disabled by
	default for now, though it can be enabled by setting
	"echopassword" in the nscp module section of nsd.tcl.
	
2000-08-21  Kris Rehberg 

	* nscp/nscp.c: Makes some attempt to recognize and handle
	telnet IAC codes like CTRL-C and CTRL-D to force a logout.
	This implementation of the telnet protocol is dirt-cheap,
	so only standard Unix telnet is supported.  On Win32, IAC
	handling is completely disabled because the client is too
	chatty with its IAC codes.

2000-08-20  Kris Rehberg 

	* nsftp, nspostgres, nssolid, nssybpd moved to $TOP level.

2000-08-17  Jim Davidson

	* nsd/dbtcl: Removed unused variables in GetCsvCmd.
	
	* nsd/adp.c: Fixed bug of not truncating output buffer when
	an error was thrown during an ns_adp_parse.  Fix suggested
	by Rob Mayoff.

	* tcl7.6 and tcl8.2.3: Switched to blocking Tcl_WaitPid to
	avoid zombies as suggested by Rob Mayoff.
	
	* thread: NULL out thread arg at exit to avoid Ns_ThreadEnum
	checking arg info for possibly deallocated context as seen
	in ns_info threads.  Also, moved read of firstPtr in
	Ns_ThreadEnum inside lock.
	
2000-08-17  Kris Rehberg 
	
	* nssock/sock.c (SockThread): warning sent to log when
	Server Busy is returned.

	* All the Makefiles should be in line with each other.
	Typing "gmake", "gmake install" and "gmake clean" should
	work in any directory.  NSHOME is paid attention to by all
	Makefiles.

	* nsd: Ns_Log and Ns_Fatal statements are hopefully more
	standardized and more useful to admins and developers.

	* Irix now builds as -o32 using the native compiler by
	default.  See Makefile.global on how to change.

2000-08-15  Kris Rehberg 

	* include/Makefile.global (INSTLOG): should have pointed
	to $(INST)/lib, not $(INST)/modules/lib.

	* Makefile: nsunix resurrected.  All modules are built.
	If a module is missing a library, it is not built, but it
	won't stop the AOLserver build process (no error is thrown).
	The build will continue with the next module.
	
	* nsftp: guesses if you have TCP_WRAPPERS available.

	* nsext: Ten guesses why $(NSHOME)/include/nsextmsg.h was
	duplicated here.

	* nssybpd: Hopefully, the log statements will be easier to
	understand by both admins and developers.  It's still messy
	since it uses syslog.  Makefile redone to use standard
	AOLserver rules.  RPATH is used a little more intelligently.
	Removed files that had no business living there.
	
	* include/Makefile.global: Took stab at RPATH support on
	Solaris to perhaps remove the need for LD_LIBRARY_PATH on
	an intelligenly-administered system.  New rule for libnspd.a.
	
	
2000-08-14  Kris Rehberg 

	* Makefile: nsvhr has been resurrected and enjoys our full
	support.

	* nsexample/Makefile: The include at the bottom wasn't using
	$(NSHOME).

2000-08-14  Jim Davidson

	* Tcl 8.x library upgraded to tcl8.3.2.

	* thread/pool.c: A spiffy range-checker added to the Zippy
	(-z) memory allocator.

2000-08-11  Kris Rehberg 

	* nsvhr/nsvhr.c: Always add "Connection: close" to the
	request line to satisfy HTTP 1.1 RFC -- this would break
	MSIE in HTTP 1.1 mode.  HTTP_EOL of "\r\n" used on all
	request lines for stupid web servers on the other end.
	Protocol "tcp" added as synonym of "http" for old-time Unix
	heads.  Lots of folks lended a hand on this one -- Satyam
	Priyadarshy, Jerry Asher, Kriston Rehberg, and special
	thanks to Wanda G. at AOL for adding a CNAME in DNS so
	quickly.

2000-08-09  Kris Rehberg 

	* nsd/serv.c: A whole lot less chatty about conns starting
	and exiting.  If you want to see them, turn on the Debug
	flag.

	* doc/*: lots of updates.  Title page extremely simplified.
	SSL docs updated.  Release notes updated.  NSV docs corrected
	(thanks to Todd Levy.

2000-08-09  Jim Davidson
	
	* tcl7.6/generic/tclFHandle.c: Removed needed fileTable
	which could result in crashes when fd's where reused quickly
	[fixes a rare multiple-exec crashing bug in nsd76 --kris].

	* thread/tcl8x.c: Added a wrapper startup for Tcl_CreateThread
	for the benefit of Win32.

	* nsd/log.c: Removed severityRank array.

	* nsd/tclmisc.c: Fixed bug with ns_info pid. [I can't code --kris]
	
	* nsd: keepalive.c,nsmain.c,sched.c,serv.c: Re-ordered
	shutdowns to ensure connection threads are stopped before
	other shutdowns begin (e.g., sched, sockcallback).
	
	* tcl8.3.1 replaces tcl8.3.0.  README.AOLSERVER added to
	tcl8.3.1 directory.  Original copies of changed are named
	*.orig.

	* include/Makefile.global: Build environment now uses gcc
	-shared -nostartfiles as the default LDSO.

	* nsthread/thread.c: Added Ns_ThreadCreate2 with extra
	flags argument used by Tcl_CreateThread to create a detached
	thread.
	
2000-08-06  Scott S. Goodwin

	* nsd/log.c: Segmentation fault was occuring when writing
	to the log file because file pointer was being assigned to
	incorrectly - it wasn't NULL and it wasn't a valid address
	within processes memory. Fixed.

2000-08-06  Scott S. Goodwin

	* nssock: You can now compile with BSAFE versions 4 and 5.
	You'll need to specify the path to your BSAFE libaries and
	the BSAFE version in the nssock/Makefile before compiling.
	If you don't have BSAFE and want to compile without SSL at
	all, edit the toplevel Makefile and take out all the "SSL=1"
	text. The files changed were nssock/Makefile and
	nssock/t_stdlib.c.

2000-08-02  Kris Rehberg 

	* Build process is a little more rule-oriented.  The cleaning
	rules "distclean" and "clobber" were removed.  The Tcl
	libraries are always distcleaned when "gmake clean" is
	invoked.  Rules that can be used as dependencies were made
	for libnsthread and the Tcl libraries -- their names are
	"libnsthread," "libtcl76," and "libtcl8x," respectively.
	PREFIX is now used as the installation directory (along
	with INST), so the more familiar "gmake install
	PREFIX=/usr/local/aolserver" will work.  Additionally,
	gmaking in a subdirectory with dependencies now works.
	
	* nsd/log.c: The sourge of modlog has been removed.  All
	code included with AOLserver that used Ns_ModLog now doesn't.
	Many log statements are now hopefully more standardized.
	This will be a continuing improvement over the next several
	updates.  I would like to use gcc's __FUNCTION__ macro but
	it doesn't work on native compilers, but we may start using
	__LINE__ and __FILE__ instead or replace Ns_Log with a
	smart macro that takes care of all this stuff for us.

	* nsd/tclmisc.c (NsTclInfoCmd): ns_info pid added to return
	the process id.

2000-08-01  Kris Rehberg 

	* nsd/adp.c (Ns_AdpRequest): The enableexpire option was
	putting an Expires header even if it already existed.

	* nsd/return.c (Ns_ConnReturnNotice): Yikes, /face should
	have been /font.  No more fonts, colors, etc, on default
	notice pages.

	* nsd/tclsock.c (NsTclSockOpenCmd): Removed spurious Ns_Log
	Notice from ns_sockopen.

	* tcl/form.tcl (ns_getform): MSIE presents the wrong stuff
	to the server when a multipart/formdata POST is redirected.
	Workaround contributed by Joseph Bank.

	* tcl/fastpath.tcl (_ns_dirlist): base href removed --
	links are now fully-qualified.

	* Makefile (install): include and lib dirs are now included
	in binary distribution.

	* tcl/http.tcl (_ns_http_gets): \n replaced by \r in all
	but _ns_http_gets so that arbitrary headers get set correctly.

	* tcl7.6/generic/tclPosixStr.c (Tcl_SignalMsg): Patch to
	Tcl 7.6 for Red Hat on SPARC architectures.  Contributed
	by Mike Chan.

2000-07-13  Kris Rehberg 

	* scripts/nsd.tcl: nssslmodule names the nsssl/nsssle
	binary's filename.  nscp_port tells nscp what port to
	listen.

	* nssock: nssock.c renamed sock.c, SSL support has been
	merged back with nssock so that both nsssl and nssock use
	identical socket code.
	
	* nsssl2: directory removed; nsssl is in the nssock directory
	now.

2000-05-09  Kris Rehberg 

	* Re-added doc directory which has had the online docs
	removed.

2000-05-02  Kris Rehberg 

	* Makefile, include/Makefile.global, include/Makefile.module,
	nsexample/Makefile: Now uses NSHOME variable to locate
	AOLserver.  NSHOME is automatically figured out in the
	top-level Makefile and all the lower Makefiles still use
	relative directory paths.  The intention of NSHOME is for
	modules that do NOT live in the AOLserver source directory
	tree.  The nsexample/Makefile explains how this works.

	* nsftp module added.  Contributed by Eric O'Laughlen.
