2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin1-10/+3
Some minor documentation cleanups were made at the same time.
2009-02-13Improve support for DOS-like systems.Lasse Collin1-0/+23
Here DOS-like means DOS, Windows, and OS/2.

message suggests.
2009-02-05Various code cleanups the the xz command line tool.Lasse Collin1-126/+6
It now builds with MinGW.
2009-01-07Use pthread_sigmask() instead of sigprocmask() when pthreadsLasse Collin1-2/+2
are enabled.
2008-12-31Remove lzma_init() and other init functions from liblzma API.Lasse Collin1-3/+0
Half of developers were already forgetting to use these functions, which could have caused total breakage in some future liblzma version or even now if --enable-small was used. Now liblzma uses pthread_once() to do the initializations unless it has been built with --disable-threads which make these initializations thread-unsafe. When --enable-small isn't used, liblzma currently gets needlessly linked against libpthread (on systems that have it). While it is stupid for now, liblzma will need threads in future anyway, so this stupidity will be temporary only. When --enable-small is used, different code CRC32 and CRC64 is now used than without --enable-small. This made the resulting binary slightly smaller, but the main reason was to clean it up and to handle the lack of lzma_init_check(). The pkg-config file lzma.pc was renamed to liblzma.pc. I'm not sure if it works correctly and portably for static linking (Libs.private includes -pthread or other operating system specific flags). Hopefully someone complains if it is bad. lzma_rc_prices[] is now included as a precomputed array even with --enable-small. It's just 128 bytes now that it uses uint8_t instead of uint32_t. Smaller array seemed to be at least as fast as the more bloated uint32_t array on x86; hopefully it's not bad on other architectures.
2008-11-19Renamed lzma to xz and lzmadec to xzdec. We create symlinksLasse Collin1-0/+402
lzma, unlzma, and lzcat in "make install" for backwards compatibility with LZMA Utils 4.32.x; I'm not sure if this should be the default though.
