322ecf93c9 Renamed lzma_options_simple to lzma_options_bcj in the API. 
The internal implementation is still using the name "simple".
It may need some cleanups, so I look at it later.

28e75f7086 Updated src/liblzma/Makefile.am to use liblzma.pc.in, which 
should have been in the previous commit.

7ed9d943b3 Remove lzma_init() and other init functions from liblzma API. 
Half of developers were already forgetting to use these
functions, which could have caused total breakage in some future
liblzma version or even now if --enable-small was used. Now
liblzma uses pthread_once() to do the initializations unless
it has been built with --disable-threads which make these
initializations thread-unsafe.

When --enable-small isn't used, liblzma currently gets needlessly
linked against libpthread (on systems that have it). While it is
stupid for now, liblzma will need threads in future anyway, so
this stupidity will be temporary only.

When --enable-small is used, different code CRC32 and CRC64 is
now used than without --enable-small. This made the resulting
binary slightly smaller, but the main reason was to clean it up
and to handle the lack of lzma_init_check().

The pkg-config file lzma.pc was renamed to liblzma.pc. I'm not
sure if it works correctly and portably for static linking
(Libs.private includes -pthread or other operating system
specific flags). Hopefully someone complains if it is bad.

lzma_rc_prices[] is now included as a precomputed array even
with --enable-small. It's just 128 bytes now that it uses uint8_t
instead of uint32_t. Smaller array seemed to be at least as fast
as the more bloated uint32_t array on x86; hopefully it's not bad
on other architectures.

050eb14d29 Revert a change made in 3b34851de1eaf358cf9268922fa0eeed8278d680 
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.

e33194e79d Bunch of liblzma tweaks, including some API changes. 
The API and ABI should now be very close to stable,
although the code behind it isn't yet.

634636fa56 Remove the alignment functions for now. Maybe they will 
be added back in some form later, but the current version
wasn't modular, so it would need fixing anyway.

653e457e37 Fix a dumb bug in .lzma decoder which was introduced in 
the previous commit. (Probably the previous commit has
other bugs too, it wasn't tested.)

17781c2c20 The LZMA2 decoder fix introduced a bug to LZ decoder, 
which made LZ decoder return too early after dictionary
reset. This fixes it.

1ea9e7f15a Added preset=NUM to --lzma1 and --lzma2. This makes it easy 
to take a preset as a template and modify it a little.

6efa2d80d4 Make the memusage functions of LZMA1 and LZMA2 encoders 
to validate the filter options. Add missing validation
to LZMA2 encoder when options are changed in the middle
of encoding.

ef7890d564 In command line tool, take advantage of memusage calculation's

cd70801520 LZMA2 decoder cleanups. Make it require new LZMA properties 
also in the first LZMA chunk after a dictionary reset in
uncompressed chunk.

656ec87882 Added lzma_delta_coder_memusage() which also validates 
the options.

c7007ddf06 Tested using COLUMNS environment variable to avoid broken 
progress indicator but since COLUMNS isn't usually available,
the code was left commented out.

files and lzmadec only .lzma files.

86a0ed8f01 Minor cleanups to xzdec. 2008-11-20 11:01:29 +02:00
Lasse Collin
1880a3927b Renamed lzma to xz and lzmadec to xzdec. We create symlinks 
lzma, unlzma, and lzcat in "make install" for backwards
compatibility with LZMA Utils 4.32.x; I'm not sure if this
should be the default though.

e114502b2b Oh well, big messy commit again. Some highlights: 
- Updated to the latest, probably final file format version.
  - Command line tool reworked to not use threads anymore.
    Threading will probably go into liblzma anyway.
  - Memory usage limit is now about 30 % for uncompression
    and about 90 % for compression.
  - Progress indicator with --verbose
  - Simplified --help and full --long-help
  - Upgraded to the last LGPLv2.1+ getopt_long from gnulib.
  - Some bug fixes
