2007-12-1480-col fixes.josh.macdonald
2007-12-14Implement UNALIGNED_OK for xd3_small_cksum_update, hoping to fix josh.macdonald
test failure on Xscale/ARM platform.
2007-12-13A few cleanups -- xd3_scksum should have been using uint32_t, but Ijosh.macdonald
doubt that is the real problem. I suspect the problem on ARM/Xscale has to do with unaligned access issues.
2007-12-07Release 3.0tjosh.macdonald
2007-12-07Patches from A. Mennucc for Debian. Fixing makfile for Cygwinjosh.macdonald
conditional compilation, which is irregular.
2007-12-06Adjust the low-end range for command_line_arguments unittest. I wish thisjosh.macdonald
didn't depend on the system rand() function, but it's portable at least.
2007-12-05Fix bug in xd3_set_source, the optimization for shiftby/maskby werejosh.macdonald
in some cases not setting those variables, which are used by xd3_blksize_div
2007-12-02Fix recode, recode test.josh.macdonald
2007-12-02Fix an off-by-one bug lurking in the array initialization josh.macdonald
in djw_compute_mtf_1_2
2007-12-02Working on the test failure in dbeug mode, partial recode test written.josh.macdonald
2007-11-27Diagnose expected non-failures test failure introfuced in 3.0s relatingjosh.macdonald
to DJW and compiler optimization level. Mysterious.
2007-11-26The rabin-karp checksum looks better in testing but doesn't reallyjosh.macdonald
seem to improve things in practice. Removed HASH_PRIME.
2007-11-15Get uniqueness and fullness metrics working, add compaction parameter forjosh.macdonald
hash-table size bias.
2007-11-13Learned a lot about Rabin-Karp performance.josh.macdonald

2007-11-11Compile with g++ 3.4.4 and add C++ checksum_test.ccjosh.macdonald
2007-11-10Adds output regarding inefficient copy instructions to "printdelta".josh.macdonald
Adds crude inefficiency check to xd3_smatch(), preventing 4-byte matches if (here-addr) >= 2^14 and 5-byte matches if (here-addr) >= 2^21. Nice improvement.
2007-11-09Release 3.0sjosh.macdonald
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.
2007-11-07Adds compare_test for benchmarking xd3_forward_match, the optimizedjosh.macdonald
version is not yet enabled in xdelta3.c
2007-10-30Update FASTEST config based on 50-round test.josh.macdonald
2007-10-29Running experiments for new -1 and -2josh.macdonald

2007-10-29Add a new fastest, fastest->faster (-2)josh.macdonald
2007-10-29Inline some functions.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.
2007-10-2880col changes.josh.macdonald
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.

2007-09-29Fixes DJW_MAX_CODELEN problem, which caused move-to-front calculationsjosh.macdonald
to run off the end of an array since there were no code-length entries in the extra codes array beyond code-length=20. Left as a TODO: document this code better so it's not so obscure.
2007-09-29Build fix for MSVC++josh.macdonald
2007-09-29Adds a test that triggers the assertion failure in djw_build_prefix,josh.macdonald
a few cleanups, but does not fix the problem (next CL).
2007-09-24Add example by Ralf Junker, who has given me permission to distribute.josh.macdonald
2007-09-22Fixes:josh.macdonald
1. Encoder was improperly setting stream->min_match on re-entry following XD3_GETSRCBLK events. 2. Decoder was improperly terminating a loop when XD3_GETSRCBLK events occur while decoding the final instruction. 3. An known assertion failure in djw_compute_mtf_1_2 will abort() in non-debug mode instead of running out of memory.
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

recode stream.
