2007-12-14Replace uint with usize_t, more portable.josh.macdonald
2007-12-14Implement UNALIGNED_OK for xd3_small_cksum_update, hoping to fix josh.macdonald
test failure on Xscale/ARM platform.
2007-12-07Patches from A. Mennucc for Debian. Fixing makfile for Cygwinjosh.macdonald
conditional compilation, which is irregular.
2007-12-02Fix recode, recode test.josh.macdonald
2007-11-26The rabin-karp checksum looks better in testing but doesn't reallyjosh.macdonald
seem to improve things in practice. Removed HASH_PRIME.
2007-11-07A few optimizations: -1 (fastest) is faster than before. -fno-builtinjosh.macdonald
makes a difference. New implementation of xd3_forward_match() is written and tested, but not enabled, needs a little more benchmarking.
2007-10-29Restore old secondary djw defaults.josh.macdonald
2007-10-29Add a new COMPLEVEL_1, previous -1 becomes -2.josh.macdonald
2007-10-29Add a new fastest, fastest->faster (-2)josh.macdonald
2007-10-29Use maskby/shiftby when source->size <= source->blksize, which helpsjosh.macdonald
xd3_process_memory() uses.
2007-10-28New xd3_blksize_div() function used everywhere to avoid __umoddi3josh.macdonald
2007-10-28Eliminate calls to __umoddi3 (compiler generated for 64-bit % 32-bit).josh.macdonald
More 80col reformatting.
2007-10-28ENC_FLUSH -> ENC_INSTRjosh.macdonald
2007-10-28Reformat for 80 cols. Allow -S djwN where N is 0-9. Defaultjosh.macdonald
(for -S djw) is 3. -S djw9 enables multi-group huffman for all three sections. -S djw3 enables single-group huffman for all three sections. 1-2 are single data-only, 3-4 are single data+inst, 5-6 are single data+inst+addr, 7, 8, 9 enable multi-group huffman for the three sections in order.
2007-10-28Reformat >80col lines. 32-bit build/test fixes.josh.macdonald
2007-10-27Cleanups on cygwin.josh.macdonald
2007-10-27Fixes for linux build.josh.macdonald
2007-10-21Comments and build with speed_test.ccjosh.macdonald
2007-10-10Removes NODECOMPRESSIZE.josh.macdonald
2007-09-13Fix secondary compression for recode. Now able to reproduce doytchin's josh.macdonald
bug report by recoding an FGK as a DJW.
2007-09-13Fix the def'n of xoff_t, at least for this linux box (thanks to cosmics.ru)..josh.macdonald
2007-09-12The "recode" command sets command-line secondary compression flags in the ↵josh.macdonald
recode stream.
2007-09-12Fixes xdelta recode command, but does not implement adler32, source josh.macdonald
info, app header, etc.
2007-09-12Add "xdelta3 recode" function, which is currently outputing incorrectjosh.macdonald
VCDIFF windows.
2007-03-24Rename #define P to #define DPjosh.macdonald
2007-02-19cleanup regtest 400 testjosh.macdonald
2007-02-18fix for windows ssize_t 3.0pjosh.macdonald
2007-02-18remove PROMOTE, SSMATCH, TRYLAZY, raise default IOPT_SIZEjosh.macdonald
2007-02-18raise default sprevsz, add command-line flag -P to setjosh.macdonald
2007-02-17generic encode tables compiled in setup.py; comments on HARDMAXWINSZ; more ↵josh.macdonald
winsize tests
2007-02-13Adds xd3_flags for setting compression level in xd3_encode_memory().josh.macdonald
2007-02-11Fixes bugs in XDELTA environment variable.josh.macdonald
Removes stream.srcwin_size variable, uses stream.src->blksize instead, to address performance regression from xdelta1. Changes the order of checksum computation to be like xdelta1, insert checksums in reverse to give preference to earlier matches. Removes svn:executable from files.
2007-02-08Python swig module working with xd3_encode_memory(), xd3_decode_memory(),josh.macdonald
and xd3_main_cmdline(). module added to xdelta3-regtest.py run-length experiments. XD3_INVALID_INPUT code added to distinguish decoder errors from invalid stream-states. xdelta3-test.py unittest added for python module. xd3_encode_memory() now limits config.winsize to <= 1MB: xd3_process_memory() now properly splits the input buffer into windows.
2007-02-07Ready to release 3.0o. Still working on swig.josh.macdonald
2007-02-07Update FASTEST, DEFAULT compression level. Comments.josh.macdonald
2007-02-04Adds a new compression level (-6), makes -1 faster and -9 better.josh.macdonald
2007-02-01Implmeent xd3_encode_memory() and xd3_decode_memory(), add comments.josh.macdonald
2007-01-29Updates on G:josh.macdonald
remove missing file from vcproj compiles under cygwin
2007-01-29Change _completely() to _completely_stream(), to introduce a new, josh.macdonald
simpler in-memory API.
2007-01-20Changes to support -I IOPT_SIZE on the commandline. New support for ↵dotdotisdead
unlimited instruction buffer size set by -I 0. The default remains 4096.
2007-01-16Increase default IOPT buffer size to 4096 entries: there is still no dotdotisdead
command-line flag for this setting! Bump version to 3.0l.
2007-01-14Cleanup the calculation of -B and -W, get the minimum source buffer size dotdotisdead
(-B) to work, enforce a maximum input window size (-W). Add some debugging output. Correct a bug in setting the large hashtable size. I've noticed some odd behavior with the -W setting, more tests to do.
2007-01-11Testing random configurations to update xdelta3-cfgs.h, preliminary.dotdotisdead
2007-01-07Removes the -M memsize flag, the #define, and stream_config field of the dotdotisdead
same name. Now computes small/large hash tables based on 1 slot per input-size/hash-width.
2006-12-16Adds /DXD3_WIN32 using native open/read/write/seek, etc, also fixing ↵josh.macdonald
get_errno and xd3_strerror. Still not 64bit tested.
2006-12-10Builds on WIN32.dotdotisdead
2006-12-10Preliminary WIN32 support.dotdotisdead
2006-09-30The XD3_INTERNAL in xd3_srcwin_move_point was caused by match_maxaddr dotdotisdead
being reset between windows. This deserves a test, but it's Friday night!
2006-09-25Cleanups, working on the python module, which has assertion failures.dotdotisdead
2006-09-24Cleanups involving xd3_smatcher and soft-config variables. Adds -M memsizedotdotisdead
to allocate larger/smaller source-checksum hash table.
