* lzdiff and lzgrep are now separate package, zutils (not packaged yet). Changelog: 2011-04-30 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.12 released. * main.cc: Added new option `-F, --recompress'. * encoder.h (update_prices): Update high length symbol prices independently of the value of `pos_state'. This gives better compression for large values of `--match-length' without being slower. * encoder.h encoder.cc: Optimize pair price calculations. This reduces compression time for large values of `--match-length' by up to 6%. * Compression time of option `-0' has been reduced by 2%. * main.cc (decompress): Print only one status line for each multimember file when only one `-v' is specified. * main.cc (decompress): Print up to 6 bytes of trailing garbage when `-vvvv' is specified. * main.cc (open_instream): Do not show the message " and `--stdout' was not specified" for directories, etc. * lziprecover.cc: If `-v' is not specified show errors only. * testsuite/unzcrash.cc: Use Arg_parser. * testsuite/unzcrash.cc: Added new options `-b', `-p' and `-s'. 2010-09-16 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.11 released. * Added new option `-0' which produces a compression speed and ratio comparable to those of `gzip -9'. * fast_encoder.h fast_encoder.cc: New files. * main.cc: Match length limit set by options -1 to -8 has been reduced to extend range of use towards gzip. Lower numbers now compress less but faster. (-1 now takes 43% less time for only 20% larger compressed size). * encoder.cc: Compression of option -9 has been slightly increased. * lziprecover.cc: Added new option `--merge' which tries to produce a correct file merging the good parts of two or more damaged copies. * lziprecover.cc: Added new option `--repair' for repairing a 1-byte error in single-member files. * decoder.cc (decode_member): Detect file errors earlier to improve efficiency of lziprecover's new repair capability. This change also prevents (harmless) access to uninitialized memory when decompressing a corrupt file. * lziprecover.cc: Added new option `--force'. * lziprecover.cc: Added new option `--output'. * lziprecover.cc: Added new option `--split' to select the until now only operation of splitting multimember files. * lziprecover.cc: If no operation is specified, warn the user and do nothing. * main.cc: Fixed warning about fchown's return value being ignored. * decoder.cc: `-tvvvv' now also shows compression ratio. * main.cc: Set stdin/stdout in binary mode on MSVC and OS2. * New examples have been added to the manual. * testsuite: `test1' renamed to `test.txt'. Added new tests. * Matchfinder types HC4 (4 bytes hash-chain) and HT4 (4 bytes hash-table) have been tested and found no better than the current BT4. 2010-04-05 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.10 released. * decoder.h: Input_buffer integrated in Range_decoder. * main.cc: File specified with option `-o' is now created with mode 0666 if umask allows it, deleted if interrupted by user. * main.cc: New constant `o_binary'. * main.cc: Dictionary size for options -2, -3, -4 and -8 has been changed to improve linearity of compressed sizes. * lzip.h: Fixed warnings produced by over-optimization (-O3). * Makefile.in: Added quotes to directory names. 2010-01-17 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.9 released. * main.cc (main): Return at least 1 if closing stdout fails. * Makefile.in: Added `--name' option to help2man invocation. * testsuite/check.sh: Use `test1' instead of `COPYING' for testing. 2009-09-02 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.8 released. * Compression time has been reduced by 4%. * Lzdiff and lzgrep have been moved to the new package zutils. * Fixed warnings on sistems where uint32_t != unsigned int. |
