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.
2009-11-14	Fix a design error in liblzma API.	Lasse Collin	4	-7/+20
	Originally the idea was that using LZMA_FULL_FLUSH with Stream encoder would read the filter chain from the same array that was used to intialize the Stream encoder. Since most apps wouldn't use LZMA_FULL_FLUSH, most apps wouldn't need to keep the filter chain available after initializing the Stream encoder. However, due to my mistake, it actually required keeping the array always available. Since setting the new filter chain via the array used at initialization time is not a nice way to do it for a couple of reasons, this commit ditches it and introduces lzma_filters_update(). This new function replaces also the "persistent" flag used by LZMA2 (and to-be-designed Subblock filter), which was also an ugly thing to do. Thanks to Alexey Tourbin for reminding me about the problem that Stream encoder used to require keeping the filter chain allocated.
2009-06-30	Build system fixes	Lasse Collin	2	-28/+23
	Don't use libtool convenience libraries to avoid recently discovered long-standing subtle but somewhat severe bugs in libtool (at least 1.5.22 and 2.2.6 are affected). It was found when porting XZ Utils to Windows <http://lists.gnu.org/archive/html/libtool/2009-06/msg00070.html> but the problem is significant also e.g. on GNU/Linux. Unless --disable-shared is passed to configure, static library built from a set of convenience libraries will contain PIC objects. That is, while libtool builds non-PIC objects too, only PIC objects will be used from the convenience libraries. On 32-bit x86 (tested on mobile XP2400+), using PIC instead of non-PIC makes the decompressor 10 % slower with the default CFLAGS. So while xz was linked against static liblzma by default, it got the slower PIC objects unless --disable-shared was used. I tend develop and benchmark with --disable-shared due to faster build time, so I hadn't noticed the problem in benchmarks earlier. This commit also adds support for building Windows resources into liblzma and executables.
2009-06-26	Fix @variables@ to $(variables) in Makefile.am files.	Lasse Collin	1	-2/+2
	Fix the ordering of libgnu.a and LTLIBINTL on the linker command line and added missing LTLIBINTL to tests/Makefile.am.
2009-04-13	Put the interesting parts of XZ Utils into the public domain.	Lasse Collin	8	-80/+24
	Some minor documentation cleanups were made at the same time.
2008-12-01	Added lzma_delta_coder_memusage() which also validates	Lasse Collin	8	-39/+75
	the options.
2008-09-27	Some API changes, bug fixes, cleanups etc.	Lasse Collin	4	-11/+11

2008-09-13	Renamed constants:	Lasse Collin	3	-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	7	-0/+407
	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.
