d64ca34f1b Use __cdecl also for function pointers in liblzma API when 
on Windows.
 2009-02-01 00:10:07 +02:00
Lasse Collin
6a2eb54092 Add LZMA_API to liblzma API headers. It's useful at least 
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h
has to be #included separately where needed.
 2009-01-31 11:01:48 +02:00

2dbdc5befb Fix two lines in lzma.h on which the # wasn't at the 
beginning of the line.

4ab7601091 Add support for using liblzma headers in MSVC, which has no 
stdint.h or inttypes.h.

3241317093 Fix uninitialized variables in alone_decoder.c. This bug was 
triggered by the previous commit, since these variables were
not used by anything before support for a preset dictionary.
 2009-01-28 08:43:26 +02:00
Lasse Collin
f76e39cf93 Added initial support for preset dictionary for raw LZMA1 
and LZMA2. It is not supported by the .xz format or the xz
command line tool yet.

2c5fe958e4 Fix a dumb bug in Block decoder, which made it return 
LZMA_DATA_ERROR with valid data. The bug was added in

128586213f Beta was supposed to be API stable but I had forgot to rename 
lzma_memlimit_encoder and lzma_memlimit_decoder to
lzma_raw_encoder_memlimit and lzma_raw_decoder_memlimit. :-(
Now it is fixed. Hopefully it doesn't cause too much trouble
to those who already thought API is stable.

4fd43cb3a9 Bumped version to 4.999.8beta right after the release 
of 4.999.7beta.

88d3e6b0b1 Cleaned up some comments in the API headers. 2008-12-31 17:15:03 +02:00
Lasse Collin
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.

4d00652e75 Updated Makefile.am that was missing from the previous commit. 2008-12-18 13:42:52 +02:00
Lasse Collin
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.

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.

c58f469be5 Added the changes for Delta filter that should have been 
part of 656ec87882ee74b192c4ea4a233a235eca7b04d4.

cd70801520 LZMA2 decoder cleanups. Make it require new LZMA properties 
also in the first LZMA chunk after a dictionary reset in
uncompressed chunk.
 2008-12-01 22:50:28 +02:00
Lasse Collin
656ec87882 Added lzma_delta_coder_memusage() which also validates 
the options.

69472ee5f0 VLI encoder and decoder cleanups. Made encoder return 
LZMA_PROG_ERROR in single-call mode if there's no output
space.

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
