2024-02-14Add SPDX license identifier into 0BSD source code files.Lasse Collin1-2/+1
2024-02-14Change most public domain parts to 0BSD.Lasse Collin1-3/+0
Translations and doc/xz-file-format.txt and doc/lzma-file-format.txt were not touched. COPYING.0BSD was added.
2014-05-04liblzma: Rename the private API header lzma/lzma.h to lzma/lzma12.h.Lasse Collin1-1/+1
It can be confusing that two header files have the same name. The public API file is still lzma.h.
2010-05-26Remove the Subblock filter code for now.Lasse Collin1-1/+0
The spec isn't finished and the code didn't compile anymore. It won't be included in XZ Utils 5.0.0. It's easy to get it back once the spec is done.
2009-11-15Add lzma_physmem().Lasse Collin1-0/+1
I had hoped to keep liblzma as purely a compression library as possible (e.g. file I/O will go into a different library), but it seems that applications linking agaisnt liblzma need some way to determine the memory usage limit, and knowing the amount of RAM is one reasonable way to help making such decisions. Thanks to Jonathan Nieder for the original patch.
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.
2008-12-31Renamed lzma_options_simple to lzma_options_bcj in the API.Lasse Collin1-1/+1
The internal implementation is still using the name "simple". It may need some cleanups, so I look at it later.
2008-12-31Remove lzma_init() and other init functions from liblzma API.Lasse Collin1-1/+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.
2008-12-17Remove the alignment functions for now. Maybe they willLasse Collin1-1/+0
be added back in some form later, but the current version wasn't modular, so it would need fixing anyway.
2008-11-25Remove the nowadays unneeded memory limitting malloc() wrapper.Lasse Collin1-1/+0
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin1-5/+1
broken. API has changed a lot and it will still change a little more here and there. The command line tool doesn't have all the required changes to reflect the API changes, so it's easy to get "internal error" or trigger assertions.
2008-06-18Update the code to mostly match the new simpler file formatLasse Collin1-4/+1
specification. Simplify things by removing most of the support for known uncompressed size in most places. There are some miscellaneous changes here and there too. The API of liblzma has got many changes and still some more will be done soon. While most of the code has been updated, some things are not fixed (the command line tool will choke with invalid filter chain, if nothing else). Subblock filter is somewhat broken for now. It will be updated once the encoded format of the Subblock filter has been decided.
2008-01-22Added lzma_easy_* functions. These should make usingLasse Collin1-0/+1
liblzma as easy as using zlib, because the easy API don't require developers to know any fancy LZMA options. Note that Multi-Block Stream encoding is currently broken. The easy API should be OK, the bug(s) are elsewhere.
