2008-01-23	Return LZMA_STREAM_END instead of LZMA_OK if	Lasse Collin	1	-1/+5
	LZMA_SYNC_FLUSH or LZMA_FULL_FLUSH is used when there's no unfinished Block open.
2008-01-23	Fix Size of Header Metadata Block handling. Now	Lasse Collin	3	-15/+15
	lzma_metadata.header_metadata_size == LZMA_VLI_VALUE_UNKNOWN is not allowed at all. To indicate missing Header Metadata Block, header_metadata_size must be set to zero. This is what Metadata decoder does after this patch too. Note that other missing fields in lzma_metadata are still indicated with LZMA_VLI_VALUE_UNKNOWN. This isn't as illogical as it sounds at first, because missing Size of Header Metadata Block means that Header Metadata Block is not present in the Stream. With other Metadata fields, a missing field means only that the value is unknown.
2008-01-23	Fix a memory leak in metadata_decoder.c.	Lasse Collin	1	-0/+1

2008-01-23	Fix the fix 863028cb7ad6d8d0455fa69348f56b376d7b908f which	Lasse Collin	1	-1/+4
	just moved to problem. Now it's really fixed.
2008-01-23	Take advantage of return_if_error() macro in	Lasse Collin	1	-16/+8
	lzma_info_metadata_set() in info.c.
2008-01-23	Fixed a dangling pointer that caused invalid free().	Lasse Collin	1	-0/+1

2008-01-22	Added lzma_easy_* functions. These should make using	Lasse Collin	7	-2/+254
	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.
2008-01-22	Fix Multi-Block Stream encoder's EOPM usage.	Lasse Collin	1	-1/+1

2008-01-22	Made lzma_extra pointers const in lzma_options_stream.	Lasse Collin	1	-2/+6

2008-01-19	Revised the Delta filter implementation. The initialization	Lasse Collin	10	-200/+363
	function is still shared between encoder and decoder, but the actual coding is in separate files for encoder and decoder. There are now separate functions for the actual delta calculation depending on if Delta is the last filter in the chain or not. If it is the last, the new code copies the data from input to output buffer and does the delta calculation at the same time. The old code first copied the data, then did the delta in the target buffer, which required reading through the data twice. Support for LZMA_SYNC_FLUSH was added to the Delta encoder. This doesn't change anything in the file format.
2008-01-16	Plugged a memory leak in stream_decoder.c.	Lasse Collin	1	-0/+20

2008-01-16	Added lzma_memlimit_count().	Lasse Collin	1	-0/+19

2008-01-16	Make Uncompresed Size validation more strict	Lasse Collin	1	-1/+2
	in alone_decoder.c.
2008-01-15	Use fastpos.h when encoding LZMA dictionary size in	Lasse Collin	1	-21/+19
	Filter Flags encoder.
2008-01-15	Revised the fastpos code. It now uses the slightly faster	Lasse Collin	1	-3/+0
	table-based version from LZMA SDK 4.57. This should be fast on most systems. A simpler and smaller alternative version is also provided. On some CPUs this can be even a little faster than the default table-based version (see comments in fastpos.h), but on most systems the table-based code is faster.
2008-01-15	Added bsr.h.	Lasse Collin	2	-0/+62

2008-01-15	Fix CRC code in case --enable-small is used.	Lasse Collin	2	-4/+0

2008-01-15	Added precomputed range coder probability price table.	Lasse Collin	1	-2/+3

2008-01-14	Small LZMA_SYNC_FLUSH fixes to Block and Single-Stream encoders.	Lasse Collin	2	-2/+3

2008-01-08	Take advantage of return_if_error() in block_decoder.c.	Lasse Collin	1	-16/+7

2008-01-08	Fix decoding of Blocks that have only Block Header.	Lasse Collin	1	-23/+14

2008-01-08	Fixed encoding of empty files. Arguments to is_size_valid()	Lasse Collin	1	-1/+1
	were in wrong order in block_encoder.c.
2007-12-11	Removed uncompressed size tracking from Delta encoder too.	Lasse Collin	1	-18/+3

2007-12-11	Remove uncompressed size tracking from the filter encoders.	Lasse Collin	1	-23/+2
	It's not strictly needed there, and just complicates the code. LZ encoder never even had this feature. The primary reason to have uncompressed size tracking in filter encoders was validating that the application doesn't give different amount of input that it had promised. A side effect was to validate internal workings of liblzma. Uncompressed size tracking is still present in the Block encoder. Maybe it should be added to LZMA_Alone and raw encoders too. It's simpler to have one coder just to validate the uncompressed size instead of having it in every filter.
2007-12-09	Added LZMA_SYNC_FLUSH support to the Copy filter.	Lasse Collin	1	-35/+57

2007-12-09	Take advantage of return_if_error() macro in more places.	Lasse Collin	5	-84/+39
	Cleaned Subblock filter's initialization code too.
