| 2007-12-14 | Replace uint with usize_t, more portable. | josh.macdonald | |
| 2007-12-14 | Fixes for Win32 and vsnprintf. | josh.macdonald | |
| 2007-12-14 | 80-col fixes. | josh.macdonald | |
| 2007-12-14 | Implement UNALIGNED_OK for xd3_small_cksum_update, hoping to fix | josh.macdonald | |
| test failure on Xscale/ARM platform. | |||
| 2007-12-13 | A few cleanups -- xd3_scksum should have been using uint32_t, but I | josh.macdonald | |
| doubt that is the real problem. I suspect the problem on ARM/Xscale has to do with unaligned access issues. | |||
| 2007-12-07 | Release 3.0t | josh.macdonald | |
| 2007-12-07 | Patches from A. Mennucc for Debian. Fixing makfile for Cygwin | josh.macdonald | |
| conditional compilation, which is irregular. | |||
| 2007-12-06 | Adjust the low-end range for command_line_arguments unittest. I wish this | josh.macdonald | |
| didn't depend on the system rand() function, but it's portable at least. | |||
| 2007-12-05 | Fix bug in xd3_set_source, the optimization for shiftby/maskby were | josh.macdonald | |
| in some cases not setting those variables, which are used by xd3_blksize_div | |||
| 2007-12-02 | Fix recode, recode test. | josh.macdonald | |
| 2007-12-02 | Fix an off-by-one bug lurking in the array initialization | josh.macdonald | |
| in djw_compute_mtf_1_2 | |||
| 2007-12-02 | Working on the test failure in dbeug mode, partial recode test written. | josh.macdonald | |
| 2007-11-27 | Diagnose expected non-failures test failure introfuced in 3.0s relating | josh.macdonald | |
| to DJW and compiler optimization level. Mysterious. | |||
| 2007-11-26 | The rabin-karp checksum looks better in testing but doesn't really | josh.macdonald | |
| seem to improve things in practice. Removed HASH_PRIME. | |||
| 2007-11-15 | Get uniqueness and fullness metrics working, add compaction parameter for | josh.macdonald | |
| hash-table size bias. | |||
| 2007-11-13 | Learned a lot about Rabin-Karp performance. | josh.macdonald | |
| 2007-11-13 | (no commit message) | josh.macdonald | |
| 2007-11-11 | Compile with g++ 3.4.4 and add C++ checksum_test.cc | josh.macdonald | |
| 2007-11-10 | Adds 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. | |||
| 2007-11-09 | Release 3.0s | josh.macdonald | |
| 2007-11-07 | A few optimizations: -1 (fastest) is faster than before. -fno-builtin | josh.macdonald | |
| makes a difference. New implementation of xd3_forward_match() is written and tested, but not enabled, needs a little more benchmarking. | |||
| 2007-11-07 | Adds compare_test for benchmarking xd3_forward_match, the optimized | josh.macdonald | |
| version is not yet enabled in xdelta3.c | |||
| 2007-10-30 | Update FASTEST config based on 50-round test. | josh.macdonald | |
| 2007-10-29 | Running experiments for new -1 and -2 | josh.macdonald | |
| 2007-10-29 | Restore old secondary djw defaults. | josh.macdonald | |
| 2007-10-29 | Add a new COMPLEVEL_1, previous -1 becomes -2. | josh.macdonald | |
| 2007-10-29 | Add a new fastest, fastest->faster (-2) | josh.macdonald | |
| 2007-10-29 | Inline some functions. | josh.macdonald | |
| 2007-10-29 | Use maskby/shiftby when source->size <= source->blksize, which helps | josh.macdonald | |
| xd3_process_memory() uses. | |||
| 2007-10-28 | New xd3_blksize_div() function used everywhere to avoid __umoddi3 | josh.macdonald | |
| 2007-10-28 | Eliminate calls to __umoddi3 (compiler generated for 64-bit % 32-bit). | josh.macdonald | |
| More 80col reformatting. | |||
| 2007-10-28 | 80col changes. | josh.macdonald | |
| 2007-10-28 | ENC_FLUSH -> ENC_INSTR | josh.macdonald | |
| 2007-10-28 | Reformat for 80 cols. Allow -S djwN where N is 0-9. Default | josh.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. | |||
| 2007-10-28 | Comments. | josh.macdonald | |
| 2007-10-28 | Reformat >80col lines. 32-bit build/test fixes. | josh.macdonald | |
| 2007-10-27 | Cleanups on cygwin. | josh.macdonald | |
| 2007-10-27 | Fixes for linux build. | josh.macdonald | |
| 2007-10-21 | Comments and build with speed_test.cc | josh.macdonald | |
| 2007-10-21 | New speed tes.t | josh.macdonald | |
| 2007-10-20 | working on inline functions | josh.macdonald | |
| 2007-10-10 | Recognize -S none. | josh.macdonald | |
| 2007-10-10 | Removes NODECOMPRESSIZE. | josh.macdonald | |
| 2007-10-10 | 3.0r release | josh.macdonald | |
| 2007-09-29 | Fixes DJW_MAX_CODELEN problem, which caused move-to-front calculations | josh.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. | |||
| 2007-09-29 | Build fix for MSVC++ | josh.macdonald | |
| 2007-09-29 | Adds a test that triggers the assertion failure in djw_build_prefix, | josh.macdonald | |
| a few cleanups, but does not fix the problem (next CL). | |||
| 2007-09-24 | Add example by Ralf Junker, who has given me permission to distribute. | josh.macdonald | |
| 2007-09-22 | Fixes: | 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. | |||
| 2007-09-13 | Fix secondary compression for recode. Now able to reproduce doytchin's | josh.macdonald | |
| bug report by recoding an FGK as a DJW. | |||
