X-Authentication-Warning: delorie.com: mail set sender to djgpp-bounces using -f Message-Id: <202102252220.11PMKTfp010909@delorie.com> Date: Thu, 25 Feb 2021 22:45:54 +0100 From: "Juan Manuel Guerrero (juan DOT guerrero AT gmx DOT de) [via djgpp-announce AT delorie DOT com]" To: djgpp-announce AT delorie DOT com Subject: ANNOUNCE: DJGPP port of lzlib 1.12 uploaded. Content-Type: text/plain; charset=ISO-8859-15; format=flowed Reply-To: djgpp AT delorie DOT com This is a port of lzlib 1.12 to MSDOS/DJGPP. lzlib is a data compression library providing in-memory LZMA compression and decompression functions, including integrity checking of the decompressed data. The compressed data format used by the library is the lzip format. lzlib is written in C. DJGPP specific changes. ======================= - There are no DJGPP specific changes to the library. Only the minilzip program has been changed to work like the port of Clzip when only SFN support is avaliable. minilzip is only build for testing purposes and not installed at all. - LFN support enabled is required to run the testsuite. The test data is binary data thus the used unzip program must treat them as binary and not as text data. - The port has been configured and compiled on WinXP SP3 and Win98SE. There is no guarantee that this may be possible with any other DOS-like OS. Due to the massive use of long file names it will not be possible to configure and compile without LFN support. To build this port you will need an OS with LFN support to configure and compile the source package. As usual, all djgpp specific files (diffs, README files, etc.) are stored in the /djgpp directory. The sources have been configured to be build in the "_build" directory. If for some reason it does not work for you, delete it contents and configure from scratch again. For further information about lzlib please read the info docs and NEWS file. Here is an extract of the NEWS file showing the user visible changes from the last port (lzlib 1.8) to this one: ------------------------------------------------------------------------------- 2021-01-02 Antonio Diaz Diaz * Version 1.12 released. * lzlib.h: Define LZ_API_VERSION as 1000 * major + minor. 1.12 = 1012. This change does not affect the soversion. * lzlib.h, lzlib.c: New function LZ_api_version. * LZd_try_verify_trailer: Return 2 if EOF at trailer or EOS marker. * Decompression speed has been slightly increased. * decoder.h: Increase 'rd_min_available_bytes' from 8 to 10. * encoder_base.c (LZeb_try_sync_flush): Compensate for the increase in 'rd_min_available_bytes'. * main.c (do_decompress): Fix false report about library stall. * main.c: New option '--check-lib'. * main.c (main): Report an error if a file name is empty. Make '-o' behave like '-c', but writing to file instead of stdout. Make '-c' and '-o' check whether the output is a terminal only once. Do not open output if input is a terminal. Replace 'decompressed', 'compressed' with 'out', 'in' in output. Set a valid invocation_name even if argc == 0. * lzlib.texi: Document the new way of verifying the library version. Document that 'LZ_(de)compress_close' and 'LZ_(de)compress_errno' can be called with a null argument. Document that sync flush marker is not allowed in lzip files. Document the consequences of not calling 'LZ_decompress_finish'. Document that 'LZ_decompress_read' returns at least once per member. Document that 'LZ_(de)compress_read' can be called with a null buffer pointer argument. Real code examples for common uses have been added to the tutorial. * bbexample.c: Don't use 'LZ_(de)compress_write_size'. * lzcheck.c: New options '-s' (sync) and '-m' (member by member). Test member by member without 'LZ_decompress_finish'. * ffexample.c: New file containing example functions for file-to-file compression/decompression. * Document extraction from tar.lz in '--help' output and man page. * Makefile.in: 'install-bin' no longer installs the man page. New targets 'install-bin-compress' and 'install-bin-strip-compress'. * testsuite: Add 9 new test files. 2019-01-02 Antonio Diaz Diaz * Version 1.11 released. * Rename File_* to Lzip_*. * LZ_decompress_read: Don't return error until all data is read. * decoder.c (LZd_decode_member): Decode truncated data until EOF. * cbuffer.c (Cb_read_data): Allow a null buffer pointer. * main.c: Don't allow mixing different operations (-d and -t). * main.c: Check return value of close( infd ). * main.c: Compile on DOS with DJGPP. * lzlib.texi: Improve descriptions of '-0..-9', '-m', and '-s'. Document that 'LZ_(de)compress_finish' can be called repeatedly. * configure: Accept appending to CFLAGS, 'CFLAGS+=OPTIONS'. * Makefile.in: Rename targets 'install-bin*' to 'install-lib*'. * Makefile.in: Targets 'install-bin*' now install minilzip. * INSTALL: Document use of CFLAGS+='-D __USE_MINGW_ANSI_STDIO'. 2018-02-07 Antonio Diaz Diaz * Version 1.10 released. * LZ_compress_finish now adjusts dictionary size for each member. * lzlib.c (LZ_decompress_read): Detect corrupt header with HD=3. * main.c: New option '--loose-trailing'. * main.c (main): Option '-S, --volume-size' now keeps input files. * main.c: Replace 'bits/byte' with inverse compression ratio. * main.c: Show final diagnostic when testing multiple files. * main.c: Do not add a second .lz extension to the arg of -o. * main.c: Show dictionary size at verbosity level 4 (-vvvv). * lzlib.texi: New chapter 'Invoking minilzip'. 2017-04-11 Antonio Diaz Diaz * Version 1.9 released. * Compression time of option '-0' has been reduced by 3%. * Compression time of options -1 to -9 has been reduced by 1%. * Decompression time has been reduced by 3%. * main.c: Continue testing if any input file is a terminal. * Change the license of the library to "2-clause BSD". ------------------------------------------------------------------------------- The port consists of the usual three packages that have been produced using djdev205 (CVS repository code) and can be downloaded from ftp.delorie.com and mirrors as (time stamp 2021-01-25): lzlib 1.12 binary and info format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2apps/lzlb112b.zip lzlib 1.12 dvi, html, ps and pdf format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2apps/lzlb112d.zip lzlib 1.12 source: ftp://ftp.delorie.com/pub/djgpp/current/v2apps/lzlb112s.zip Send lzlib specific bug reports to .
