2022-11-28	liblzma: Remove lzma_lz_decoder_uncompressed() as it's now unused.	Lasse Collin	1	-3/+0

2022-11-27	liblzma: Pass the Filter ID to LZ encoder and decoder.	Lasse Collin	1	-1/+2
	This allows using two Filter IDs with the same initialization function and data structures.
2022-07-13	liblzma: Add optional autodetection of LZMA end marker.	Lasse Collin	1	-3/+5
	Turns out that this is needed for .lzma files as the spec in LZMA SDK says that end marker may be present even if the size is stored in the header. Such files are rare but exist in the real world. The code in liblzma is so old that the spec didn't exist in LZMA SDK back then and I had understood that such files weren't possible (the lzma tool in LZMA SDK didn't create such files). This modifies the internal API so that LZMA decoder can be told if EOPM is allowed even when the uncompressed size is known. It's allowed with .lzma and not with other uses. Thanks to Karl Beldan for reporting the problem.
2016-11-21	liblzma: Avoid multiple definitions of lzma_coder structures.	Lasse Collin	1	-7/+6
	Only one definition was visible in a translation unit. It avoided a few casts and temp variables but seems that this hack doesn't work with link-time optimizations in compilers as it's not C99/C11 compliant. Fixes: http://www.mail-archive.com/xz-devel@tukaani.org/msg00279.html
2012-07-17	liblzma: Make the use of lzma_allocator const-correct.	Lasse Collin	1	-3/+4
	There is a tiny risk of causing breakage: If an application assigns lzma_stream.allocator to a non-const pointer, such code won't compile anymore. I don't know why anyone would do such a thing though, so in practice this shouldn't cause trouble. Thanks to Jan Kratochvil for the patch.
2010-05-26	Rename MIN() and MAX() to my_min() and my_max().	Lasse Collin	1	-1/+1
	This should avoid some minor portability issues.
2009-04-13	Put the interesting parts of XZ Utils into the public domain.	Lasse Collin	1	-12/+5
	Some minor documentation cleanups were made at the same time.
2009-04-10	Fix off-by-one in LZ decoder.	Lasse Collin	1	-1/+1
	Fortunately, this bug had no security risk other than accepting some corrupt files as valid.
2009-01-27	Added initial support for preset dictionary for raw LZMA1	Lasse Collin	1	-1/+8
	and LZMA2. It is not supported by the .xz format or the xz command line tool yet.
2008-12-15	Fix data corruption in LZMA2 decoder.	Lasse Collin	1	-3/+5

2008-11-19	Oh well, big messy commit again. Some highlights:	Lasse Collin	1	-2/+2
	- Updated to the latest, probably final file format version. - Command line tool reworked to not use threads anymore. Threading will probably go into liblzma anyway. - Memory usage limit is now about 30 % for uncompression and about 90 % for compression. - Progress indicator with --verbose - Simplified --help and full --long-help - Upgraded to the last LGPLv2.1+ getopt_long from gnulib. - Some bug fixes
2008-08-28	Sort of garbage collection commit. :-\| Many things are still	Lasse Collin	1	-147/+161
	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	-3/+7
	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.
