Age	Commit message (Collapse)	Author	Files	Lines
2024-02-14	Add SPDX license identifier into 0BSD source code files.	Lasse Collin	1	-0/+2

2024-02-14	Change most public domain parts to 0BSD.	Lasse Collin	1	-3/+0
	Translations and doc/xz-file-format.txt and doc/lzma-file-format.txt were not touched. COPYING.0BSD was added.
2023-10-30	liblzma: Use lzma_attr_visibility_hidden on private extern declarations.	Lasse Collin	1	-0/+7
	These variables are internal to liblzma and not exposed in the API.
2023-01-12	Fix warnings from clang -Wdocumentation.	Lasse Collin	1	-4/+0

2016-03-13	liblzma: Disable external SHA-256 by default.	Lasse Collin	1	-10/+6
	This is the sane thing to do. The conflict with OpenSSL on some OSes and especially that the OS-provided versions can be significantly slower makes it clear that it was a mistake to have the external SHA-256 support enabled by default. Those who want it can now pass --enable-external-sha256 to configure. INSTALL was updated with notes about OSes where this can be a bad idea. The SHA-256 detection code in configure.ac had some bugs that could lead to a build failure in some situations. These were fixed, although it doesn't matter that much now that the external SHA-256 is disabled by default. MINIX >= 3.2.0 uses NetBSD's libc and thus has SHA256_Init in libc instead of libutil. Support for the libutil version was removed.
2015-11-02	liblzma: Fix a build failure related to external SHA-256 support.	Lasse Collin	1	-9/+23
	If an appropriate header and structure were found by configure, but a library with a usable SHA-256 functions wasn't, the build failed.
2011-05-21	liblzma: Try to use SHA-256 from the operating system.	Lasse Collin	1	-8/+75
	If the operating system libc or other base libraries provide SHA-256, use that instead of our own copy. Note that this doesn't use OpenSSL or libgcrypt or such libraries to avoid creating dependencies to other packages. This supports at least FreeBSD, NetBSD, OpenBSD, Solaris, MINIX, and Darwin. They all provide similar but not identical SHA-256 APIs; everyone is a little different. Thanks to Wim Lewis for the original patch, improvements, and testing.
2009-04-13	Put the interesting parts of XZ Utils into the public domain.	Lasse Collin	1	-4/+3
	Some minor documentation cleanups were made at the same time.
2009-02-08	Add a separate internal function to initialize the CRC32	Lasse Collin	1	-0/+1
	table, which is used also by LZ encoder. This was needed because calling lzma_crc32() and ignoring the result is a no-op due to lzma_attr_pure.
2008-12-31	Remove lzma_init() and other init functions from liblzma API.	Lasse Collin	1	-16/+9
	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.
2008-08-28	Sort of garbage collection commit. :-\| Many things are still	Lasse Collin	1	-45/+22
	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.
2008-06-18	Update the code to mostly match the new simpler file format	Lasse Collin	1	-12/+35
	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.
