2022-07-24	liblzma: Add optional autodetection of LZMA end marker.	Lasse Collin	1	-1/+1
	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.
2019-12-31	liblzma: Fix warnings from -Wsign-conversion.	Lasse Collin	1	-4/+4
	Also, more parentheses were added to the literal_subcoder macro in lzma_comon.h (better style but no functional change in the current usage).
2016-12-28	liblzma: Avoid multiple definitions of lzma_coder structures.	Lasse Collin	1	-13/+19
	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	-4/+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.
2011-03-31	liblzma: Fix decoding of LZMA2 streams having no uncompressed data.	Lasse Collin	1	-4/+4
	The decoder considered empty LZMA2 streams to be corrupt. This shouldn't matter much with .xz files, because no encoder creates empty LZMA2 streams in .xz. This bug is more likely to cause problems in applications that use raw LZMA2 streams.
2010-10-19	Clean up a few FIXMEs and TODOs.	Lasse Collin	1	-1/+0
	lzma_chunk_size() was commented out because it is currently useless.
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.
2009-01-27	Added initial support for preset dictionary for raw LZMA1	Lasse Collin	1	-3/+6
	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	-4/+11

2008-12-01	Make the memusage functions of LZMA1 and LZMA2 decoders	Lasse Collin	1	-5/+2
	to validate the filter options.
2008-12-01	LZMA2 decoder cleanups. Make it require new LZMA properties	Lasse Collin	1	-54/+41
	also in the first LZMA chunk after a dictionary reset in uncompressed chunk.
2008-09-27	Some API changes, bug fixes, cleanups etc.	Lasse Collin	1	-5/+5

2008-09-13	Renamed constants:	Lasse Collin	1	-3/+3
	- LZMA_VLI_VALUE_MAX -> LZMA_VLI_MAX - LZMA_VLI_VALUE_UNKNOWN -> LZMA_VLI_UNKNOWN - LZMA_HEADER_ERRRO -> LZMA_OPTIONS_ERROR
2008-08-28	Sort of garbage collection commit. :-\| Many things are still	Lasse Collin	1	-0/+318
	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.
