Lasse Collin d4a0462abe liblzma: Avoid multiple definitions of lzma_coder structures. 
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.

Lasse Collin 117d962685 liblzma: Fix a compression-ratio regression in LZMA1/2 in fast mode. 
The bug was added in the commit
f48fce093b and thus
affected 5.1.4beta and 5.2.0. Luckily the bug cannot
cause data corruption or other nasty things.

Lasse Collin 6bf5308e34 liblzma: Use lzma_memcmplen() in fast mode of LZMA. 2014-07-25 22:29:49 +03:00
Lasse Collin 974ebe6349 liblzma: Rename a few variables and constants. 
This has no semantic changes. I find the new names slightly
more logical and they match the names that are already used
in XZ Embedded.

The name fastpos wasn't changed (not worth the hassle).

Lasse Collin 920a69a8d8 Rename MIN() and MAX() to my_min() and my_max(). 
This should avoid some minor portability issues.

Lasse Collin eb7d51a3fa Collection of language fixes to comments and docs. 
Thanks to Jonathan Nieder.

Lasse Collin 02ddf09bc3 Put the interesting parts of XZ Utils into the public domain. 
Some minor documentation cleanups were made at the same time.

Lasse Collin 050eb14d29 Revert a change made in 3b34851de1 
that was related to LZMA_MODE_FAST. The original code is slightly
faster although it compresses slightly worse. But since it is fast
mode, it is better to select the faster version.

Lasse Collin 1dcecfb09b Some API changes, bug fixes, cleanups etc. 2008-09-27 19:09:21 +03:00
Lasse Collin 3b34851de1 Sort of garbage collection commit. :-| Many things are still 
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.
