Lasse Collin 2c5fe958e4 Fix a dumb bug in Block decoder, which made it return 
LZMA_DATA_ERROR with valid data. The bug was added in
e114502b2b.

Lasse Collin 00be5d2e09 Remove dead code. 2009-01-19 13:52:36 +02:00
Lasse Collin 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.

Lasse Collin b056379490 Updated THANKS. 2009-01-15 14:29:22 +02:00
Lasse Collin dc8f3be06d Fixed a bug in 7z2lzma.bash to make it work with .7z files 
that use something else than 2^n as the dictionary size.
Thanks to Dan Shechter for the bug report.
 2009-01-15 14:27:32 +02:00
Lasse Collin 8286a60b8f Use pthread_sigmask() instead of sigprocmask() when pthreads 
are enabled.
 2009-01-07 18:41:15 +02:00
Lasse Collin 4fd43cb3a9 Bumped version to 4.999.8beta right after the release 
of 4.999.7beta.
 2008-12-31 20:01:00 +02:00
Lasse Collin 061748f593 Disable Subblock filter from test_compress.sh since it is 
disabled by default in configure.ac.
 2008-12-31 18:59:02 +02:00
Lasse Collin 9c45658ddc Disable both Subblock encoder and decoder my default, 
since they are not finished and may have security issues too.
 2008-12-31 17:44:20 +02:00
Lasse Collin b59f1e98f5 Update some files in debug directory. 2008-12-31 17:42:50 +02:00
Lasse Collin d1d17a40d3 Prepare for 4.999.7beta release. 2008-12-31 17:41:46 +02:00
Lasse Collin 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.
 2008-12-31 16:29:39 +02:00
Lasse Collin 7eea8bec3a Fixed missing quoting in configure.ac. 2008-12-31 00:57:27 +02:00
Lasse Collin 28e75f7086 Updated src/liblzma/Makefile.am to use liblzma.pc.in, which 
should have been in the previous commit.
 2008-12-31 00:48:23 +02:00
Lasse Collin 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.

Lasse Collin 5cda29b566 Use 28 MiB as memory usage limit for encoding in test_compress.sh. 2008-12-27 19:40:31 +02:00
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.
 2008-12-27 19:32:20 +02:00
Lasse Collin 4820f10d0f Some xz command line tool improvements. 2008-12-27 19:30:19 +02:00
Lasse Collin 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.
 2008-12-27 19:27:49 +02:00
Lasse Collin 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.
 2008-12-17 21:49:53 +02:00
Lasse Collin 4fed98417d xz message handling improvements 2008-12-17 20:11:23 +02:00
Lasse Collin 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.)
 2008-12-15 23:26:43 +02:00
Lasse Collin 671a5adf1e Bunch of liblzma API cleanups and fixes. 2008-12-15 19:39:13 +02:00
Lasse Collin 17781c2c20 The LZMA2 decoder fix introduced a bug to LZ decoder, 
which made LZ decoder return too early after dictionary
reset. This fixes it.
 2008-12-15 14:26:52 +02:00
Lasse Collin f9f2d1e743 Added two new test files. 2008-12-15 11:20:22 +02:00
Lasse Collin ff7fb2c605 Fix data corruption in LZMA2 decoder. 2008-12-15 10:01:59 +02:00
Lasse Collin 1ceebcf7e1 Name the package "xz" in configure.ac. 2008-12-13 00:54:11 +02:00
Lasse Collin a94bf00d0a Some adjustments to GCC warning flags. The important change 
is the removal of -pedantic. It messes up -Werror (which I
really want to keep so that I don't miss any warnings) with
printf format strings that are in POSIX but not in C99.
 2008-12-12 22:43:21 +02:00
Lasse Collin 8582d392ba Remove obsolete comment. 2008-12-10 01:31:00 +02:00
Lasse Collin b1ae6dd731 Use "decompression" consistently in --long-help. 2008-12-10 01:27:15 +02:00
Lasse Collin 1ea9e7f15a Added preset=NUM to --lzma1 and --lzma2. This makes it easy 
to take a preset as a template and modify it a little.
 2008-12-10 01:23:58 +02:00
Lasse Collin bceb3918db Put the file format specification into the public domain. 
Same will be done to the actual code later.
 2008-12-09 17:43:31 +02:00
Lasse Collin 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.
 2008-12-09 17:41:49 +02:00
Lasse Collin f20a03206b Updated THANKS. 2008-12-09 10:36:24 +02:00
Lasse Collin ef7890d564 In command line tool, take advantage of memusage calculation's 
ability to also validate the filter chain and options (not
implemented yet for all filters).
 2008-12-01 23:04:12 +02:00
Lasse Collin ccd57afa09 Validate the filter chain before checking filter-specific 
memory usage.
 2008-12-01 22:59:28 +02:00
Lasse Collin c596fda40b Make the memusage functions of LZMA1 and LZMA2 decoders 
to validate the filter options.
 2008-12-01 22:58:22 +02:00
Lasse Collin c58f469be5 Added the changes for Delta filter that should have been 
part of 656ec87882.
 2008-12-01 22:55:18 +02:00
Lasse Collin 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.
 2008-12-01 16:30:11 +02:00
Lasse Collin 691a9155b7 Automake includes the m4 directory, so don't add it in 
Makefile.am separately.

Updated THANKS.
