2008-08-28	Sort of garbage collection commit. :-\| Many things are still	Lasse Collin	1	-228/+0
	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.
2008-06-19	Add limit of lc + lp <= 4. Now we can allocate the	Lasse Collin	1	-7/+6
	literal coder as part of the main LZMA encoder or decoder structure. Make the LZMA decoder to rely on the current internal API to free the allocated memory in case an error occurs.
2008-06-11	Fix uninitialized variable in LZMA encoder. This was	Lasse Collin	1	-0/+2
	introduced in 369f72fd656f537a9a8e06f13e6d0d4c242be22f.
2008-06-01	Fix a buffer overflow in the LZMA encoder. It was due to my	Lasse Collin	1	-4/+5
	misunderstanding of the code. There's no tiny fix for this problem, so I also cleaned up the code in general. This reduces the speed of the encoder 2-5 % in the fastest compression mode ("lzma -1"). High compression modes should have no noticeable performance difference. This commit breaks things (especially LZMA_SYNC_FLUSH) but I will fix them once the new format and LZMA2 has been roughly implemented. Plain LZMA won't support LZMA_SYNC_FLUSH at all and won't be supported in the new .lzma format. This may change still but this is what it looks like now. Support for known uncompressed size (that is, LZMA or LZMA2 without EOPM) is likely to go away. This means there will be API changes.
2008-03-22	Demystified the "state" variable in LZMA code. Use the	Lasse Collin	1	-2/+3
	word literal instead of char for better consistency. There are still some names with _char instead of _literal in lzma_optimum, these may be changed later. Renamed length coder variables. This commit doesn't change the program logic.
2008-03-10	Really fix the price count initialization.	Lasse Collin	1	-2/+2

2008-03-10	Initialize align_price_count and match_price_count in	Lasse Collin	1	-0/+2
	lzma_encoder_init.c. While we don't call fill_distances_prices() and fill_align_prices() in lzma_lzma_encoder_init(), we still need to initialize these two variables so that the fill functions get called in lzma_encoder_getoptimum.c in the beginning of a stream.
2008-01-15	Revised the fastpos code. It now uses the slightly faster	Lasse Collin	1	-22/+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.
