2007-12-24  Simson Garfinkel  <simsong@imac2.local>

	* afflib.spec.in (Name): Joachim Metz contributed this file.

2007-12-18  Simson Garfinkel  <simsong@Obsidian.local>

	* lib/vnode_afd.h (AFD_DEFAULT_MAXSIZE): Changed from 600 to 608
	(so that it is now a multiple of 16; not strictly needed, but it
	makes things a bit cleaner.)

	* lib/afflib.cpp (af_update_segf): fixed crasher on update when
	af->crypto->encrypt was not present.

	* tools/affuse.c (main): improved error messages for when affuse
	can't run.

2007-12-14  Simson Garfinkel  <simsong@Obsidian.local>

2007-11-26  Simson L. Garfinkel  <simsong@t.eecs.harvard.edu>

	* REMOVED lib/sha256.c --- the implementation had bugs. (That's
	what I get for including a non-validated crypto algorithm.) AFF
	now requires SHA256 but it should compile without it

	* tools/afsegment.cpp (main): now handles case when optarg==0
	(which happened with afsegment -d seg instead of affsegment -dseg)
	(usage): added : to "d" in getopt.

2007-11-24  Simson Garfinkel  <simsong@imac2.local>

	* lib/crypto.cpp: refactored AFF compilation error message

2007-11-16  Simson L. Garfinkel  <simsong@t.eecs.harvard.edu>

2007-11-14  Simson L. Garfinkel  <simsong@t.eecs.harvard.edu>

	* lib/afflib.h: af_is_badsector now takes const unsigned char
	*buf; taking non-const was an error

2007-11-13  Simson L. Garfinkel  <simsong@domex.local>

	* lib/afflib_sha256.h: minor tweaks to deal with the problem with
	SHA256() and EVP_sha256() are present but not in the #include file.

2007-11-07  Simson L. Garfinkel  <simsong@t.eecs.harvard.edu>

	* tools/afsegment.cpp (main): -q renamed to be -Q (because -q
	should be quiet)
	(main): only prints filename if there is more than one file
	(main): only prints segname if there is more than one seg

2007-10-31  Simson Garfinkel  <simsong@imac2.local>

	* tools/utils.cpp: added #ifdef AFF_SIGS so that bom class won't
	be compiled if not compiling with AFFSIGS
	added #include <afflib_i.h> to get #ifdef AFF_SIGS

2007-10-29  Simson Garfinkel  <simsong@imac2.local>

	* tools/afinfo.cpp (info_file): aes_segs now initialized to
	0. (Strangely, the uninitialized value was causing problems when
	running with MSC.)

	* lib/vnode_s3.cpp (s3_cantopen): added "return -1" to s3_cantopen()

	* lib/vnode_aff.cpp (aff_get_next_seg): ENOBUFS error on
	incomplete reads changed to E2BIG, since there is no ENOBUFS on windows.

	Windows without OpenSSL

	* lib/afflib_util.cpp (af_parse_url): index() changed to strchr()
	for Win32.

2007-10-24  Simson Garfinkel  <simsong@imac2.local>

	* lib/afflib.h: significant changes for compiling under win32. 
	- added u_int and others for compiling under win32.
	- affkey_aes256 structure had an element with the same name;
	structure renamed to affkey.

2007-10-20  Simson Garfinkel  <simsong@imac2.local>

	* lib/vnode_afm.cpp (afm_split_raw_setup): modified so that
	ap->aff->image_size only needs to equal ap->sr->image_size if
	ap->aff->image_size has already been set

2007-10-18  Simson Garfinkel  <simsong@imac2.local>

	* lib/vnode_split_raw.cpp (split_raw_get_seg): fixed bug in that
	*datalen was not set properly if it was smaller than the size of
	the segment, even if data==0. Fixed.

2007-10-16  Simson Garfinkel  <simsong@imac2.local>

	* lib/vnode_split_raw.cpp (split_raw_update_seg): was returning
	the number of bytes written; now returns 0 if write is successful,
	-1 if it is not.

2007-10-14  Simson Garfinkel  <simsong@imac2.local>

        * aimage/aimage.cpp (usage): --sign and -s now used to specify
	private and public key used for signing.
	
	* aimage/aimage.cpp (usage): --setseg used to be -s; changed to -g
	so that we can use -s for signing.

2007-09-25  Simson Garfinkel  <simsong@m-ern-nps-edu.local>

	* tools/utils.cpp (get_seglist): fixed uninitialized variables in
	get_seglist which was causing indeterminate behavior in get_seglist.

2007-09-16  Simson Garfinkel  <simsong@Obsidian.local>

	* BUGLIST.txt (library): removed need to check for af->writing,
	because it's gone.

2007-09-15  Simson Garfinkel  <simsong@Obsidian.local>

	* lib/afflib.h: removed af->writing, because it wasn't good for
	POSIX compatibility. 

2007-09-14  Simson L. Garfinkel  <simsong@t.eecs.harvard.edu>

	* tools/afcopy.cpp (main): -c option (verify compression) removed
	from usage because it was never implemented. New -c will specify
	an X.509 certificate.

2007-09-12  Simson L. Garfinkel  <simsong@t.eecs.harvard.edu>

	* MULTIPLE FILES: changed most "const void *" pointers on update
	and write routines to "const u_char *".

2007-09-02  Simson L. Garfinkel  <simsong@t.eecs.harvard.edu>


	* lib/aff_toc.cpp (aff_toc_del): fixed double-del problem; thanks
	to Jason Shiffer for bringing this to our attention.

2007-08-29  Simson Garfinkel  <simsong@m.ern.nps.edu>

	* lib/afflib.cpp (af_open_with): added support for AFFLIB_PASSPHRASE

2007-08-27  Simson Garfinkel  <simsong@m.ern.nps.edu>

	* aimage/aimage.cpp (process_option): made opt_maxsize an int64;
	added support for dvd and dvddl from luca at palazzo.name.

2007-08-20  Simson Garfinkel  <simsong@Obsidian.local>

	* lib/aftest.cpp (aestest): now sets page size in test files.

	* lib/afflib.cpp (af_update_seg): af_update_seg() didn't check to
	make sure that writing was enabled. Now it does.

2007-08-20  Simson Garfinkel  <simsong@m.ern.nps.edu>

	* lib/afflib_stream.cpp (af_write): Now sets pagesize to
	AFF_DEFAULT_PAGESIZE (1024*1024*16) if a write is attempted
	without a pagesize being previously set.

2007-08-18  Simson Garfinkel  <simsong@Obsidian.local>

	* configure.ac: increased version to 2.4.0

	* lib/aff_db.cpp (af_backspace): af_backspace will no longer
	backspace from the first segment in the file.

	* lib/vnode_aff.cpp (aff_write_ignore): BUG --- if first segment
	was deleted, entire file got wiped. Whoops! fixed this.

	* tools/afcopy.cpp (afcopy): bugfix - removed af_close(out.af);
	when zapping; file wasn't open.

2007-08-17  Simson Garfinkel  <simsong@Obsidian.local>

	* lib/vnode_s3.cpp (s3_open): revised for URL parsing in afflib.cpp

	* lib/vnode_aff.cpp (aff_create): moved af_make_badflag to afflib.cpp
	(aff_get_next_seg): now sets errno to ENOBUFS if buffer isn't
	large enough to hold requested data. 

2007-08-16  Simson Garfinkel  <simsong@Obsidian.local>

	* lib/vnode_aff.cpp (aff_open): changed all occurances of af_toc
	to aff_toc since the TOC is an AFF-file specific thing.

	* tools/afinfo.cpp (usage): changed -p option (validate the hash
	of each page) to -v 

2007-08-12  Simson Garfinkel  <simsong@Obsidian.local>

	* tools/afinfo.cpp (print_info): added two spaces to the "data
	length" printout. 

2007-08-11  Simson Garfinkel  <simsong@Obsidian.local>

	* tools/afinfo.cpp (info_file): fixed printing of missing pages
	with -a when there was no device sector size.

	* lib/afflib.cpp: added support for openssl/fips_sha.h

	* S3 support is now disabled by default. 

2007-08-11  Simson Garfinkel  <simsong@m.ern.nps.edu>

	* lib/s3_glue.cpp: removed main() if USE_S3 was not defined. What
	was I thinking?

2007-07-29  Simson Garfinkel  <simsong@Obsidian.local>

	* tools/afcopy.cpp (main): Removed -p option; now just has -X1
	through -X9 and -L for recompressing; these are the same flags as aimage.

	* lib/afflib.cpp (af_open): attempts to open a file for writing
	with an invalid name now sets EINVAL.


2007-07-26  Simson Garfinkel  <simsong>

	* tools/afxml.cpp (xml_info): removed use of af_backspace() so
	this will now work with S3.
	(xml_info): hex is now printed with coding='base16', decimal
	numbers now printed coding='base10'
	(xml_info): printable data now just printed, rather than encoded

2007-07-25  Simson Garfinkel  <simsong>

	* lib/afflib_stream.cpp (af_write): added check for valid
	image_pagesize in af_write if the write bypass is not used. 

	* lib/vnode_aff.cpp (aff_update_seg): removed stale "append" comment.

2007-07-19  Simson Garfinkel  <simsong>

	* lib/afflib.cpp (af_seek): af_seek w/ SEEK_CUR didn't work. It
	was doing SEEK_CUR as SEEK_SET. This is now fixed. SEEK_END was
	working. 
	(af_seek): added automatic detection of random access, which now
	changes the af_update_seg algorithm.

	* lib/vnode_aff.cpp (aff_write_ignore): modified so that if an
	IGNORE segment is written before another IGNORE, they are
	combined. Likewise, if one is written after an IGNORE, they are
	combined.
	(aff_update_seg): modified so that new objects smaller than 4096
	will not be dropped into deleted segments larger than 4096 bytes
	to prevent fragmentation.

2007-07-18  Simson Garfinkel  <simsong>

	* lib/vnode_aff.cpp (aff_update_seg): if the last segment is NULL,
	it is now erased before writing.
	
	(aff_del_seg): now we use this on Windows, since _chsize_s() is a
	good analog for ftruncate()

	* lib/aftest.cpp (reverse_test): reverse test now reads data to
	verify it is correct

2007-07-17  Simson Garfinkel  <simsong>

	* lib/s3.cpp: applied patches from Ted Romer.  The 'cat' and 'cp'
	commands in s3.cpp had a bug where they neglect to skip over the
	command name in argv, with the result that cat always tries to
	look for the key 'cat' and 'cp' always tries to copy the file
	'cp'.

	This patch fixes that, and also modifies cat and rmdir to accept
	multiple arguments.
	
2007-07-16  Simson L. Garfinkel  <simsong@t.eecs.harvard.edu>

	* lib/aftest.cpp (sparse_test): added read-at-end and
	read-beyond-end of sparse file tests to aftest -6

	* lib/afflib_stream.cpp (af_read): removed break so that reads on
	pages that don't exist return NULs rather than errors.

2007-07-14  Simson L. Garfinkel  <simsong>

	* lib/vnode_s3.cpp: changed AF_IDENTIFY_AFD to AF_IDENTIFY_S3
	Modified system so that if s3 support is not compiled in, s3:///
	names generate an error.

	* lib/afflib_i.h: changed from int64 to int64_t and from uint64 to uint64_t.

2007-07-13  Simson L. Garfinkel  <simsong>

	* Removed #define UNIX. Now we have #ifdef HAVE_POPEN (which is
	what we really wanted, anyway)

	* Added support for uint64_t; uint64 now is a typedef for it.
	* Added support for int64_t; int64 now is a typedef for it.

2007-07-11  Simson L. Garfinkel  <simsong>

	* tools/afcopy.cpp (afcopy): cleaned up printing a bit
	(afcopy): fixed -y option, which apparently didn't work

	* lib/afflib_pages.cpp (af_read_sizes): removed &arg from
	af_get_next_seg call. This change makes af_read_sizes()
	dramatically faster on s3 because the calls can be satisfied by
	reading the directory, rather than the need to read every
	individual segment.

	* tools/afinfo.cpp (print_info): added -X flag to print segment names without data contents.

	* lib/afflib_pages.cpp (af_get_page): only fills buffer with "bad flag" if a buffer is provided.

	is still not being called.

2007-04-29  Simson L. Garfinkel  <simsong>

	* lib/vnode_raw.cpp (raw_popen): moved hasmeta() to af_hasmeta()
	and put in afflib_util.cpp.

2007-04-29  Simson Garfinkel  <simsong>

	format string in warn().

	* aimage/aimage.cpp (getlock): command line parameter no longer
	used as format string in err()

	* tools/afxml.cpp (xml_info): added name sanitization to AFF XML
	names per VSecurity report

	* aimage/imager.cpp (image_loop): fixed important bug when imaging
	from /dev/random (or presumably a network connection) which caused
	page 0 to be repeatedly rewritten.

2007-04-02  Simson Garfinkel  <simsong>

	* aimage/ident.cpp (get_params): changed occurances of strcpy() to
	strlcpy() and strcat() to strlcat() per VSecurity report.

	network provided by Suessmilch Bernd

2007-02-01  Simson Garfinkel  <simsong>

	* fixed bugs in the caching system; caching now works.

2007-01-24  Simson Garfinkel  <simsong>

	* lib/afflib.h: moved #include <sys/types.h> from afflib_i.h to afflib.h

	* lib/afflib.h: Moved #ifndef PACKAGE_TARNAME from afflib.h to afflib_i.h

	* lib/afflib.cpp (af_eof): uses results from af_vstat() instead of
	calling af_imagesize() again (which would be another call to vstat)

2007-01-23  Simson Garfinkel  <simsong>

	* lib/aff_toc.cpp (af_toc_build): changed malloc(0) to
	malloc(sizeof(af_toc_mem)) as on Borland C++, malloc(0) returns a
	NULL pointer.

	* lib/afflib.cpp (af_open_with): fixed memory leak in error condition.

	* lib/vnode_aff.cpp (aff_open): added "b" to opens for running
	under windows.

	* lib/vnode_raw.cpp (raw_get_seg): added support for phantom
	segments AF_PAGESIZE and AF_IMAGESIZE. This fixes the bug with
	afconvert that had been previously reported. 

2007-01-11  Simson L. Garfinkel  <simsong>

	* lib/vnode_afd.cpp: moved definitions of F_OK and R_OK to this file.

	* lib/afflib_pages.cpp: added #include to malloc.h for
	valloc. Perhaps it should go in afflib_i.h?

	* aimage/aimage_os.cpp (ident): fixed handling if ident is not defined

	* tools/unix4win32.cpp: removed this file because it shouldn't be
	needed anymore; warn, warnx, err and errx are now provided by
	afflib. 

	* lib/afflib_i.h: created proper configure macros for HAVE_ERR,
	HAVE_ERRX, HAVE_WARN and HAVE_WARNX to handle the presence of
	absence of these on multiple platforms. 

2006-12-27  Simson L. Garfinkel  <simsong>

	* lib/s3_glue.cpp (request): Added CURLOPT_TIMEOUT 60*60 (1 hour)
	to S3 transactions.

2006-12-14  Simson L. Garfinkel  <simsong>

	* lib/afflib_pages.cpp (af_read_sizes): modified af_read_sizes so
	that if an image file doesn't have an IMAGESIZE segment, the
	imagesize is determined by reading all of the segments

2006-11-28  Simson L. Garfinkel  <simsong>

2006-11-27  Simson L. Garfinkel  <simsong>

	* lib/s3_glue.cpp (canonical_string): added support for BAD_STL,
	so that on pair, where STL is out-of-date, we can still compile

	* lib/vnode_afd.cpp (afd_add_file): wasn't setting sectorsize on
	AFD subfiles. This caused problems with files that had sector
	sizes of 1024 bytes...
	
	* (afd_add_file): files now added to array before new file is set up.

2006-11-25  Simson L. Garfinkel  <simsong>

	* lib/vnode_afd.cpp (afd_update_seg): corrected multiple
	definitions of AFFILE *af2, which might cause compiling problems
	under Windows

	* lib/afflib_i.h: Added AFFLIB_TRACE environment variable; right
	now it just traces seek and read

	* lib/afflib.h: retyped af_seek to take an int64 instead of a uint64

	* lib/vnode_s3.cpp (s3_open): All S3 environment variables are now
	defined in s3_glue.h

2006-11-18  Simson L. Garfinkel  <simsong>

	* aimage/aimage.cpp (debug_list): changed -L option (Log file) to
	-G so that -L could be used for LZMA compression.

2006-10-31  Simson L. Garfinkel  <simsong>

	* lib/s3_glue.cpp (request): changed CURLOPT_INFILESIZE_LARGE to
	CURLOPT_INFILESIZE. This limits maximum requests to 2GB in length,
	but I don't think that this will be a significant problem, and the
	LARGE was causing problems on Linux.

2006-10-27  Simson L. Garfinkel  <simsong>

	* lib/afflib_pages.cpp (af_set_pagesize): no longer complains if
	pagesize it being set to what it already is

	* tools/afcopy.cpp: added -z (opt_zap) to overwrite existing files.

2006-10-26  Simson L. Garfinkel  <simsong>

	* lib/afflib_pages.cpp: fixed bytes==0 bug in af_get_page. Now if
	bytes==0, it probes for the page existence and then returns.

	* lib/s3_glue.cpp (request): Added up to 3 retries for S3 "500"
	internal errors.

2006-10-22  Simson L. Garfinkel  <simsong>

	* lib/afflib.cpp (af_identify_type): Added flag to allow user to
	specify if file must exist or not. 

	* lib/vnode_s3.cpp (s3_get_seg): Now uses "HEAD" to probe length
	of segment without downloading segment. Note that the
	Content-Length: header needs to be decoded.

2006-10-21  Simson L. Garfinkel  <simsong>

	* aimage/aimage.cpp (process_config_questions): Now has conditional detection
	of readline; if it isn't present, defaults to fgets()


2006-10-20  Simson L. Garfinkel  <simsong>

	* Moved AFFLIB to gnu build environment (autoconf, automake,
	configure, etc.). Apparently I can now edit this file by doing a
	C-x 4 a. How cool! More information at:
	http://gnu.j1b.org/software/emacs/manual/html_node/Change-Log.html

Release 1.8.0:
- Added support for storing files on Amazon S3. 
  Set Environment variable AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.
  Set variable AWS_DEFAULT_BUCKET.
  Filename syntax is s3://bucket/filename.aff
  or:
  s3:///foo/bar/baz/filename.aff

  Bucket is getenv("AWS_DEFAULT_BUCKET") unless otherwise specified. 
  Buckets are automatically created if they do not exist (and if nobody else has created
  that bucket yet.)

  Remember, there is a limit of 100 buckets per customer.

- Moved af_read_sizes(af) from each open to af_open(). This means that I need
  to re-validate all of the various implementations.

- API simplification: The "append" flag has been dropped from af_update_seg() and
  af_update_segq(). None of my code ever had append==0, and to make S3 handle it
  sensibly would have required a second round-trip to the server.

- Removed errors from LZMA routines

Release 1.7.1:
- Fixed isdigit() call, which isn't available under Linux


Release 1.7.0:

- Moved AFFINFO mailing list to Google Groups. Actualy, to two groups
  on Google Groups: aff-users and aff-announce. Everybody on AFFINFO
  has been subscribed to aff-announce. 

- Added a new compression algorithm, AF_PAGE_COMP_ALG_ZERO. This algorithm 
  detects a page of all 0s and simply notes that fact, rather than passing
  the sectors through zlib.

- Added a new comparession algorithm, AF_PAGE_COMP_ALG_LZMA, which implements
  the LZMA compression algorithm. Validated LZMA against a terrabyte of compressed
  page images and found no errors in decompression. LZMA averages are,
  on average, 1/3 to 1/10th the size of the ZLIB-compressed images. 

library:
- AFFLIB now maintains a two-page cache for every open AFFILE; this
  can be expanded at runtime to any number by setting
  AFFLIB_CACHE_PAGES environment variable to the number of pages that
  you want to keep in memory. Since pages are typically 16MB, setting
  this variable to 16 will dedicate 256MB to each open AFF file
  (assuming that you are reading the file through the page system; the
  memory only gets dedicated when the bytes actually get read.)

- You can also set the AFFLIB_CACHE_STATS environment variable to 1,
  which will put on STDERR the cache information every time you close
  a file.
  
- Renamed "af_is_badblock" to "af_is_badsector".

- Removed logfile from AFFILE structure. It was just being used for
  debugging, and not in a particularly effective way. (af_seek and
  af_write no longer reference it. )

- Fixed linking under MacOS for strlcpy problem.

- Integrated LZMA library

- Got AFFLIB (but not the tools) to compile under MS VC6++. Because the Microsoft
  compiler is pretty picky about some things, a whole bunch of signed/unsigned errors
  were found and fixed. (not that they would have ever mattered, but...)
  LZMA is not included in the Windows release currently
    
afcopy:
- Created new tool, afcopy, which copies an AFF file segment-by-segment,
  and verifies each segment after it is copied by reading the resulting file.
  afcopy thus validates all writes and has the side-effect of compressing files, 
  so the resulting file may be smaller than the original.

- Added "-p" option to afcopy to preen (recompress with LZMA).

afcompare:
- Added -p option to report on preening
- Added -r option to compare directories recurisvely
- Added -j option to just do the data


Release 1.6.33:
- Fixed to compile under Kubuntu 6.0.6

Release 1.6.32:
- pages in AFFILES now have MD5s stored automatically as well. So when
"page3" is written, "page3_md5" is also written. 
- afinfo 
     - when it sees any segment with "md5" in its name that is 16-bytes long, the segment is printed
       in hex. Likewise when a segment has "sha1" in its name and is 20-bytes long.
     - New "-p" option checks the hash for every page.
- aimage: MacOS 10.4 demsg now requires root to run; aimage no longer sends dmesg error to stderr. 
  Instead, errors go to /dev/null, and if there is no dmesg output, no dmesg segment is created.

Release 1.6.31:
Make release now clearly requires gmake and errors if Berkeley Make is used

Release 1.6.30:
Removed dependency on #include <warn.h> from building the library.

Release 1.6.29:
Fixed "reverse" option (-V) on aimage so that it actually works.

Release 1.6.28:
Typedef for "u64" defined under linux so that afflib will compile under Slackware

Release 1.6.27:
- Compiles under Cygwin
- Aimage now has a -Y (--batch) option which prints 
  line-by-line output, so that the program can be easily
  incorporated into other programs.

Release 1.6.24:
AFFLIB no longer assumes that <warnx.h> is installed on cygwin.

Release 1.6.24:
Library and some of the tools now compiles under CYGWIN. 
Programs that rely on termcap don't compile. This includes
aimage and afconvert.


Release 1.6.22:
afxml now displays the same values without base64 encoding as afinfo

Release 1.6.20:
Library should now compile on NetBSD and OpenBSD. Let me know if it doesn't

Release 1.6.19:
Library (but nothing else) now compiles on solaris with GCC

Release 1.6.18:
Now compiles with either Berkeley make or gmake

Release 1.6.17:
af_read:
- returns 0 if attempt made to read a file with no bytes.
- returns -1 if attempt made to read a file with no pagesize defined.

aimage:
- Erases screen junk of amount of freespace on disk goes from 1000MB to 999MB

Release 1.6.16:
aimage:
- Fixed a bug in report printing without going back into \r\l mode.
- fixed error handling when disk fills up. 

Release 1.6.15:
- Removed aff file in tools directory. Sorry about that.

Release 1.6.14:
afxml:
 - metadata segments that just had an arg and no data are now reported as
   <segname>###</segname>, rather than <segname arg=### />
aimage:
 - minor cosmetic improvements


Release 1.6.13:
lib:
 - error message on split_raw_setup clarified
 - af_open now returns 0 if it can't open the file

aimage:
 - now has flags to suppress inclusion of dmesg and ethernet address in AFF file.
 - scaled_atoi now checks its parameters better.
 - cleaned up display on 25x80 display
 - cleaned up display when imaging multiple drives
 - --setseg now works
 - now handles improperly-mastered CDROMs


Release 1.6.12:
lib:
  - fixed badflag handling (badflags were only 4 bytes due to 
    variable sector size changes.)

Release 1.6.11:
vnode_afm:
  af_callback now gets propigated from afm layer to split_raw layer
  on af_write.
lib:
  AFFLIB now has a "parent" pointer which is set for AFM and AFD.
  callback now uses the parent instead of self if parent is set
aimage:
  -v now prints the version number and exits.
  -V now scans in reverse.


Release 1.6.9:
aimage:
- Whoops. Broke update logic in 1.6.8. Fixed

Release 1.6.8:
aimage:
- remove foo.000 and foo.afm from release

Release 1.6.7:
lib:
- Fixed release system so that release X can't be made if release X is already on the server
- Fixed bug in vnode_raw implementation resulting from move to 64-bit math

aimage:
- modified aimage so that it only updates the screen (and queries the timer)
  every million bytes read
- by default, no log file is written

afinfo:
- prints hex digits as DDDD EEEE FFFF now
- fixed behavior of sha1 printing --- it breaks by two lines by default


Release 1.6.6:
lib:
- moved check on change of imagesize on close from aff_close to af_close.
  Now check is done for AFM files in addition to AFF files. This fixes the
  bug of the AF_IMAGESIZE segment not being written by aimage with AFM files.
- renamed af->image_size_orig to af->image_size_in_file to make it more clear what it does
- created new segment type "aff_file_type" which holds AFF for AFF files, AFM for AFM files,
  and AFD for AFD files. 
- created aff_create() and afm_create() functions which are automatically
  called by the corresponding _open() functions when a file is created.
- removed af_set_maxsize64; af_set_maxsize now requires a 64-bit argument
- created new function, af_set_sectorsize()
- sectorsize no longer hard-coded to be 512.
- removed af_demand_sizes; sizes are now assumed read when the file is opened
- no longer calls err() in af_open
- Virus hiding claim removed from FAQ

TOOLS:
- all tools take "-v" to print their version number. Tools that were using
  -v for "verbose' have been changed

afcat:
- checks for -1 return from af_read

afconvert:
- all math involving pages changed to 64-bits
- now honors opt_quiet

afinfo:
- -d command now returns pagesize in addition to page number
- -w command now implemented properly

aimage:
- error message with -E omitted no longer misleading
- Checks for ifconfig in path before running ifconfig

afcompare:
- -v no longer is verbose
- -a prints things that are the same
- -b prints sector numbers that were different
- -c prints contents of sectors that are different.


Release 1.6.5:
afconvert:
- 'm' and 'k' changed back to mod 1024, not mod 1000
- imagesize segment now written when converting from raw to afm

aimage:
- SIGINFO #ifdefed so that it only is included if SIGINFO is defined.


Release 1.6.4:
- afconvert and afinfo fixed to handle 0 read bytes from af_read()

Release 1.6.3:
- af_set_sizes() call removed.
- fixed bug in af_cat
- several bugs in AFM implementation fixed.

- fixed af_eof() for AFF implementation.

Release 1.6.1:
vnode_afd:
- Support for AFD was inadvertantly broken in 1.6.0; it's fixed in 1.6.1

Release 1.6.0:
vnode_split_raw.cpp:
- integrated code from Joel Weber with these significant changes:
- Removed dependency on AFF/AFD/AFM implementation
- changed implementation to use lseek() to write empty files, rather than repeated writes of buffers...
- modified split_raw_get_seg so that it called af_segname_page_number() rather than parsing by hand.
- created afm_update_seg() so that we could remove call to afm_identify_file in split_raw_update_seg
- fixed a bug whereby 256K of raw files were created if maxsize was smaller than ZERO_BUFFER_SIZE,
  which was hard-coded to 256K
- removed raw_file_size from split_raw_private, as it was redundent with maxfilesize in the AFFILE structure.

vnode_afm.cpp:
- integrated code form Joel Weber with these significant changes:
- Opens two sub-files, one for the AFM metadata (through a coerced aff_open()), and one 
  for the split_raw implementation.
- Note: there is still a bug that AFM files can't be opened for extending; 

lib:
- added af_has_pages() to allow higher-level programs to know if the underlying
  vnode implementation supports pages or not.
- af_vnode_info: added has_pages flag so that an implementation can tell the higher
  layers if it supports pages or not.
- vnode_raw: made it so that af_popen() now tells the higher layers that pages are not
  supported.
- af_vnode_info: added use_eof and at_eof flags, to support EOF reporting on af_popen.
- awaiting af_read() & af_write() bypass, pending code from nemo

afcat:
- Outputs NULs for bad blocks unless -b is given. 

afconvert:
- Added version to usage.
- Fixed conversion of gzip'ed and bzip'ed raw images
- Calls af_has_pages to see if the input vnode implementation supports pages or not.
  If it doesn't, then it just reads from the beginning of the image to the end.
- Implemented -O (outdir) flag

afinfo:
- Now honors -w flag
- Output squished to fit MD5s and SHA1s.

aimage:
- Properly prints free space on FreeBSD, MacOS and Linux
- Prints MD5 & SHA1 as groups of 4 upper-case letters.
- Now stores sectorsize in "sectorsize" segment
- Now stores number of sectors that the device has in "devicesectors" segment
- --pagesize= option now allows suffix of b, k, m or g
- ACQUISTION_TIME now correct (it was being saved as a 64-bit number but reported as a 
  32-bit number in afinfo.)



Release 1.5.13:
Encase support works for multiple encase files.
       .E01, .E02 ... .E99

Release 1.5.12:
aimage:
- now allows --maxsize=cd and --maxsize=bigcd
- --no_hash (-H) avoids hash calculation

Release 1.5.10:
makefiles:
- Finally implemented a single makefile along the lines
  of the "Recursive Make considered Harmful" paper, but improved,
  with targets that work in both the subdirectories and in the root directory.
  Currently it only works with gmake, which is only a problem under FreeBSD.

Release engineering:
- added a "tests" directory and moved end-to-end testing there.
  afconvert, afcat, and aimage are now automatically tested as part of the release
  process.

aimage:
- no longer dumps core when not given an output file.
- Doesn't waste left-most column of screen
- Displays elapsed time when running.
- Now displays elapsed time while imaging
- Now displays aimage version
- Saves total time to image a disk in the AFF file.
- Properly indicates free space left on capture disk.

Release 1.5.9:
- Fixed bug in release system which was giving incorrect filenames
- fixed bug in AFD which wasn't setting image size properly in the sub AFF files
- fixed bug in AFD support where maxsize wasn't being set on default. 
  Now it defaults to 600M

Release 1.5.8:
- Fixed progname bug (progname appears to only exist under
  freeBSD)

Release 1.5.7:
- fixed a few bugs regarding AFD performance

afcompare:
- -v flag (verbose) implemented. When run without -v, doesn't report similarities.
- corrected a bug when a data segment was in one file but not another.


Release 1.5.6:
- More options added to afcat for handling segments.
aimage:
- aimage now puts now information into aff files.



Release 1.5.5:
lib:
- Eliminated bug when an afd file was opened read-only of the library
  giving error messages that it was unable to copy over metadata from
  the first AFF file to the other AFF files.
- AFFLIB is now tolerant of a trailing / on .afd names.
- Stores AFFLIB version in the AFF file when new files are created.

afcat:
- now prints AFFLIB version number.
- now prints a warning on STDOUT if a page is skipped; suppress with -q
- no longer clobbers output file without warning
- no longer give errors about not being able to "update"
  information when it cats out an AFD file.


afcompare:
- now prints AFFLIB version number

afinfo:
- Now prints AFFLIB version number.
- Option -v no longer validates hash codes
- Option -m validates MD5 codes
- Option -s validates SHA1 codes
- No longer prints the total compression efficiency

afstats:
- Now prints AFFLIB version number

afxml:
- Now prints AFFLIB version number
- Puts AFFLIB version number as a comment in XML output

release:
- fixed bug of executables in release tar file

aimage:
- ETA acronym removed; now says "Done in:"




Release 1.5.4:
afconvert:
- significant changes in option parsing to make it more reliable.
- Now properly handles creating files with non-standard AFF segment sizes
- change to "-z" option so that it zaps the output file, not the input file
  (to make consistent with other af commands.)

release engineering:
- auotmatic validation of afconvert and afcat as part of the release cycle

Release 1.5.3:
aimage
- Minor patch so it should write afd files...


Release 1.5.1:
- fixed suffixing for -M command in aimage
aimage:
- Now reads serial numbers of USB memory sticks using sysctl -a.
- NOTE: Be sure that ther eis only one USB memory stick in the system when you do this,
  because we can't figure out how to match the stick up with the S/N other than the
  manufacturer's name.

Release  1.5
lib:
- Initial support of EVF file format. (Only works on Intel right now, not PPC) 

afconvert:
- rewrote to use vnode support

aimage:
- Initial support for split files

Release 1.4.1:
aimage:
- fixed bug when encountering errors and imaging from a device. 
  (The error is that additional bad blocks were being written into the file with
   out proper BAD SECTOR headers. No real data was corrupted, but in some cases
   random data appeared in the image file which should not have been written.)
- Improved error recovery. Previously, 5 attempts were made to read the sectors that failed, after
  which the program gave up. Now it skips forward and tries to read the next set of sectors. It repeats
  this whole process until there is a bad region that is equal 2.5 times the size of the 
  default read (256K). 

lib:
- fixed bug in which small pages were written out with too much data
- fixed bug in af_get_page in which invalid data was being left uninitialized rather than 
  being initialized with the bad_block flag


-Release 1.4
Terminology change: data segments are renamed "pages" to eliminate confusion with AFF segments. 

lib:
- Implemented a "vnode" abstraction to make it easy to work with multiple file systems.
- Found and fixed at least 10 major bugs. None of them would have caused data corruption,
  but some would have caused the library to go into an infinite loop or to crash.
- Support for "AFD" files --- these are directories of AFF files. This will allow AFF
  to work with file systems that do not support files larger than 2^32 characters 
  (such as FAT32). 


Known bugs:
AImage: bad block flags are not being properly written out in AFF files. 

afinfo:
- prints more information about AFF files in an easy-to-read format

afcompare:
- Now compares two AFF files, or an AFF and a RAW file.

-Release 1.3.4
aimage:'
- Dramatic restructing of the program. 
- You can now batch multiple aimage commands on a single command line.
  The program surveys total amount of data to copy and a grand-total ETA.
- New -A option will write out a segment with compression, a segment without
  compression, and then will go with the fastest approach.
- Better graphics
- Prints a certificate when the imaging is finished

lib:
- Removed call to fpurge(), which was incorrect.
- renamed aff_ to aff_toc, becuase it really is building a
  table of contents.

-Release 1.3.3
lib:
- Improved error handling in writing segments. 
- More information is now provided to segment writing callback function. 

aimage:
- Removed the --info command, since it was just for debugging.
- Made --make-config a flag that creates the config file if it doesn't exist,
  but it uses the name provided by --config.
- Revamped config file. 
- removed some global variables that weren't being used; folded others into the 
  imager class.
- fixed bug in aimage when reading from devices whose length cannot be determined 
  (e.g. /dev/zero, (tapes, TCP connections)

aconvert:
- No longer core-dumps if the file that it is asked to convert doesn't exist.

January 9, 2006 - Release 1.3.3
aimage:
- added a -A flag which makes aimage compress or not compress, whichever is faster.


January 9, 2006 - Release 1.3.2
Overall:

aimage:
- Some curses testing code was left in. It's been removed.

January 8, 2006 - Release 1.3.1.
Overall:
- Moved source for aimage to aimage/ directory
- Move source for tools to tools/ directory

aimage:
- On Linux, now reads the serial number of USB drives that are being imaged
  using the /proc file system. 

tools:



December 31, 2005 - Release 1.3.0
overall:
- Moved library source code into lib/ subdirectory. 
  One big makefile still makes it all, see
  "Recursive make considered harmful."
  http://www.canb.auug.org.au/~millerp/rmch/recu-make-cons-harm.html

afcat:
- Now only outputs the segments containing data.
  It does this by first scanning and making a list of all the data segments;
  It then seeks to the location of each one in the virtual file, reads 
  the segment worth of data, and sends it to stdout.

afconvert:
- When outputing with the -o option, now outputs an AFF file if file ends
  '.aff' and outputs raw if file does not end .aff
- The -x (no compression) flag now works. 
- The -X (set compression level) flag has been implemented. 
- As a result, you can now batch compress a set of uncompressed AFF files

Release 1.2.9
afconvert:
- fixed crashing bug when converting raw files to aff files
- fixed crashing bug when converting aff files to raw files.


December 21, 2005 - Release 1.2.8

library:
- AF_BADBLOCKS is now initialized to 8 bytes of NULs, rather than 
  a 0-length segment.
- fixed corruption bug in af_del_seg().
- Added (tm).

aimage:
- Fixed calculation of free space on the disk for FreeBSD.
- Made display more attractive. 
- Added support for automatically rescanning scsi bus. 
  You can now scan the scsi bus and image by specifying "scsi1", for 
  example, to image from scsi bus 1.  (FreeBSD only.)
- Added optional preview to let you see the data as it is recorded.
  This is great for spotting drives that have been 'sanitized' or
  cleared.
- Displays size of target disk in GB/MB/KB 
- Doesn't compute hash for raw image if the image is invalid 
  (if aimage did an lseek.)
- Now captures ATA serial number even if disk can't be imaged. 
- Prints final report of image results  

afconvert:
- fixed crashing bug in afconvert.
- Corrected incorrect "progname" in many utilities.

afinfo:
- More tolerant of errors in aff file.

affix:
- Initial Release
- Can fix a file that is not properly terminated by removing junk at end.
  This is useful if a computer crashes while aimage is being run.

December 6, 2005 - Release 1.2.7
- Minor fixes for makedepend problems that people on various platforms had

November 18, 2005 - Release 1.2.5
- Implemented segment directory; list of all segments is now kept
  in memory, rather than read on-the-fly from the disk. This 
  dramatically improves performance on random-access test. 
  Library falls back to old method of scanning the file for
  each segment if the segment list is too large to hold in memory.
  Time for aftest -3 improves on my laptop from TK seconds to 27 seconds.
  

November 18, 2005 - Release 1.2.4
- redesigned afflib for improved performance.
- afconvert can now convert from one AFF to another AFF.

October 21, 2005 - Release 1.2.1
- Added a whole bunch of segment names.
- Found a nasty bug in updating of segments under certain circumstances
- Lots of new features in aimage

October 20, 2005 - Release 1.2.0
- created atest for heavy-duty testing of af_seek()
- support for reading drive SN under Linux and FreeBSD
- found bug in af_seek()

October 11, 2005 - Release 1.1.1
- Modified af_open() so it read data_segsize on open.  
- changed af_setsize() to af_set_sizes(). Now it doesn't allow you to change the
  data segment size if it has already been set.
- Modified convert to handle gzipped files with gzcat.
- Fixed but in aconvert where infiles were not being closed.
- removed fancy image size calculation from ainfo, as it wasn't right for compressed files.
- Added -Wall and found lots of signage bugs
- Cleanly compiles on Linux; supports > 2GB files


September 11, 2005 - Release 1.1
- Added support for writing files with af_write().
- New files now automatically get bad block flag created
- fixed afflib for AMD64 architectures.
- ainfo wasn't calculating SHA-1 properly for -v option on AMD64. Fixed.
  ainfo wasn't printing compression overhead properly. Fixed. Also fixed
  small buffer overflow in printing of SHA-1 values.
- changed "radio" typo to "ratio."
- aconvert now aborts (and deletes AFF file) if ^C is pressed or if
  a write fails.
- aconvert now refuses to convert an AFF file. Added af_identify(fname) to 
  return true if a file is probably an AFF file and false if it is not.

August 14, 2005 - Release 1.0.1
- changed minor bug in aconvert in handling of multiple files

August 13, 2005	- Release 1.0

Initial Release of AFFLIB. Includes library description, README, basic
library functionality, and four utilities.
