2009-05-01Renamed the file format specification to xz-file-format.txtLasse Collin1-0/+0
which is the filename used on the WWW.
2009-04-28Fixed a crash in liblzma.Lasse Collin11-13/+13
liblzma tries to avoid useless free()/malloc() pairs in initialization when multiple files are handled using the same lzma_stream. This didn't work with filter chains due to comparison of wrong pointers in lzma_next_coder_init(), making liblzma think that no memory reallocation is needed even when it actually is. Easy way to trigger this bug is to decompress two files with a single xz command. The first file should have e.g. x86+LZMA2 as the filter chain, and the second file just LZMA2.
2009-04-15Fix uint32_t -> size_t in ARM and ARM-Thumb filters.Lasse Collin2-2/+2
On 64-bit system it would have gone into infinite loop if a single input buffer was over 4 GiB (unlikely).
2009-04-14Minor fixes to test files' README.Lasse Collin1-8/+9
2009-04-13Updated history.txt.Lasse Collin1-57/+66
2009-04-13Quick & dirty update to support xz in diff/grep/more scripts.Lasse Collin7-75/+119
2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin206-2023/+868
Some minor documentation cleanups were made at the same time.
2009-04-10Fix off-by-one in LZ decoder.Lasse Collin1-1/+1
Fortunately, this bug had no security risk other than accepting some corrupt files as valid.
2009-03-31Fix minor typos in READMEPavel Roskin1-3/+3
2009-03-31Add a note and work-around instructions to README aboutLasse Collin1-0/+11
problems detecting a C99 compiler when some standard headers are missing.
2009-03-18Updated THANKS.Lasse Collin1-0/+1
2009-03-18Fix wrong macro names in lc_cpucores.m4 and cpucores.h.Lasse Collin2-4/+4
Thanks to Bert Wesarg.
2009-03-01Test for Linux-specific sysinfo() only on Linux systems.Lasse Collin1-9/+19
Some other systems have sysinfo() with different semantics.
2009-03-01Added AC_CONFIG_MACRO_DIR to configure.ac.Lasse Collin1-0/+1
2009-03-01Fix the Autoconf test for getopt_long replacement.Lasse Collin1-0/+4
It was broken by e114502b2bc371e4a45449832cb69be036360722.
2009-02-22Add a rough explanation of --extreme to output of --help.Lasse Collin1-0/+4
2009-02-22Fixes to progress message handling in xz:Lasse Collin3-213/+351
- Don't use Windows-specific code on Windows. The old code required at least Windows 2000. Now it should work on Windows 98 and later, and maybe on Windows 95 too. - Use less precision when showing estimated remaining time. - Fix some small design issues.
2009-02-18Added files missing from the previous commit.Lasse Collin2-1/+39
2009-02-17Added lzma_easy_buffer_encode(). Splitted easy.c into smallLasse Collin8-49/+185
pieces to avoid unneeded dependencies making statically linked applications bigger than needed.
2009-02-15Make physmem.h work on old Windows versions.Lasse Collin1-4/+27
Thanks to Hongbo Ni for the original patch.
2009-02-14Fix microsecond vs. nanosecond confusion in my_time().Lasse Collin1-1/+1
2009-02-14Cleanups to the code that detects the amount of RAM andLasse Collin10-130/+235
the number of CPU cores. Added support for using sysinfo() on Linux systems whose libc lacks appropriate sysconf() support (at least dietlibc). The Autoconf macros were split into separate files, and CPU core count detection was moved from hardware.c to cpucores.h. The core count isn't used for anything real for now, so a problematic part in process.c was commented out.
2009-02-13Initial port to DOS using DJGPP.Lasse Collin3-0/+524
2009-02-13Windows port: Take advantage of the version number macros.Lasse Collin3-24/+9
Now the version number is not duplicated in the Windows-specific files anymore.
2009-02-13Changed how the version number is specified in various places.Lasse Collin6-7/+95
Now configure.ac will get the version number directly from src/liblzma/api/lzma/version.h. The intent is to reduce the number of places where the version number is duplicated. In future, support for displaying Git commit ID may be added too.
2009-02-13Fix handling of integrity check type in the xz command line tool.Lasse Collin2-1/+12
2009-02-13Improve support for DOS-like systems.Lasse Collin10-30/+86
Here DOS-like means DOS, Windows, and OS/2.
2009-02-11Remove dead directories from .gitignore.Lasse Collin1-2/+0
2009-02-11.gitignore vs. MakefilesJim Meyering1-0/+22
How about this for those of us who do srcdir builds?
2009-02-10Removed Makefile from .gitignore since not all MakefilesLasse Collin1-1/+0
in the repository are generated by Autotools. People should do test builds in a separate build directory anyway.
2009-02-10Added resource files for the Windows build.Lasse Collin6-15/+88
2009-02-09Let the user specify custom CFLAGS on the make commandLasse Collin2-29/+31
line. Previously custom CFLAGS worked only when they were passed to configure.
2009-02-08Fix aliasing issue in physmem.h.Lasse Collin1-9/+10
2009-02-08Add a separate internal function to initialize the CRC32Lasse Collin3-3/+12
table, which is used also by LZ encoder. This was needed because calling lzma_crc32() and ignoring the result is a no-op due to lzma_attr_pure.
2009-02-08Make "xz --force" to write to terminal as the errorLasse Collin1-1/+1
message suggests.
2009-02-08Support both slash and backslash as path componentLasse Collin1-0/+9
separator on Windows when parsing argv[0].
2009-02-07Omit the wrong and (even if corrected) nowadays useless rmLasse Collin1-28/+0
from autogen.sh.
2009-02-07Updated THANKS.Lasse Collin1-0/+1
2009-02-07Make it easy to choose if command line tools should beLasse Collin3-7/+45
linked statically or dynamically against liblzma. The default is still to use static liblzma, but it can now be changed by passing --enable-dynamic to configure. Thanks to Mike Frysinger for the original patch. Fixed a few minor bugs in configure.ac.

2009-02-07Assume 32 MiB of RAM on unsupported operating systems likeLasse Collin1-1/+1
the comment in hardware.c already said.
2009-02-07MinGW support: Don't build fastpos_tablegen.c as part ofLasse Collin2-33/+69
liblzma. Build both static and dynamic liblzma, and also static and dynamic versions of the command line tools.
2009-02-07Support LZMA_API_STATIC in assembler files toLasse Collin2-0/+6
avoid __declspec(dllexport) equivalent.
2009-02-07Introduced LZMA_API_STATIC macro, which the applicationsLasse Collin2-8/+25
need to #define when linking against static liblzma on platforms like Windows. Most developers don't need to care about LZMA_API_STATIC at all.
2009-02-06Another grammar fixLasse Collin1-1/+1
2009-02-06Grammar fix in README.Lasse Collin1-1/+1
2009-02-06Some MSYS installations (e.g. MsysGit) don't includelarhzu/v4.999.8betaLasse Collin2-10/+13
install.exe, so don't rely on it.
2009-02-06Recreated the BCJ test files for x86 and SPARC. The old filesLasse Collin5-1/+1
were linked with crt*.o, which are copyrighted, and thus the old test files were not in the public domain as a whole. They are freely distributable though, but it is better to be careful and avoid including any copyrighted pieces in the test files. The new files are just compiled and assembled object files, and thus don't contain any copyrighted code.
2009-02-05Add the "windows" directory to EXTRA_DIST.Lasse Collin1-0/+1
2009-02-05Added initial experimental makefile for use with MinGW.Lasse Collin3-0/+597
2009-02-05Various code cleanups the the xz command line tool.Lasse Collin18-246/+399
It now builds with MinGW.
2009-02-03Another utime() fix.Lasse Collin1-4/+5
2009-02-03Fix wrong filename argument for utime() and utimes().Lasse Collin1-2/+2
This doesn't affect most systems, since most systems have better functions available.
2009-02-02Updated the x86 assembler code:Lasse Collin3-28/+144
- Use call/ret pair to get instruction pointer for PIC. - Use PIC only if PIC or __PIC__ is #defined. - The code should work on MinGW and Darwin in addition to GNU/Linux and Solaris.
2009-02-02Modify LZMA_API macro so that it works on Windows withLasse Collin54-176/+177
other compilers than MinGW. This may hurt readability of the API headers slightly, but I don't know any better way to do this.
2009-02-01Fix a bug in lzma_block_buffer_decode(), although thisLasse Collin1-4/+4
function should be rewritten anyway.
2009-02-01Added initial version of raw buffer-to-buffer codingLasse Collin4-20/+221
functions, and cleaned up filter.h API header a little. May be very buggy, not tested yet.
2009-02-01Fix missing newlines in xzdec.c.Lasse Collin1-3/+3
2009-02-01Use __cdecl also for function pointers in liblzma API whenLasse Collin3-20/+20
on Windows.
2009-01-31Add LZMA_API to liblzma API headers. It's useful at leastLasse Collin17-88/+131
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h has to be #included separately where needed.
2009-01-31Use _WIN32 instead of WIN32 in xzdec.c to test if compiling on Windows.Lasse Collin1-2/+2
2009-01-31Fix two lines in lzma.h on which the # wasn't at theLasse Collin1-2/+2
beginning of the line.
2009-01-31Add support for using liblzma headers in MSVC, which has noLasse Collin1-24/+46
stdint.h or inttypes.h.

2009-01-28The .xz file format specification version 1.0.0 is nowLasse Collin1-35/+49
officially released. The format has been technically the same since 2008-11-19, but now that it is frozen, people can start using it without a fear that the format will break.
2009-01-28Updated THANKS.Lasse Collin1-0/+1
2009-01-28Fix uninitialized variables in alone_decoder.c. This bug wasLasse Collin1-0/+2
triggered by the previous commit, since these variables were not used by anything before support for a preset dictionary.
2009-01-27Added initial support for preset dictionary for raw LZMA1Lasse Collin8-27/+77
and LZMA2. It is not supported by the .xz format or the xz command line tool yet.

2009-01-26Tiny bit better sanity check in block_util.cLasse Collin1-1/+1
2009-01-25Fix a dumb bug in Block decoder, which made it returnLasse Collin1-3/+3
LZMA_DATA_ERROR with valid data. The bug was added in e114502b2bc371e4a45449832cb69be036360722.

2009-01-20Use LZMA_PROG_ERROR in lzma_code() as documented in base.h.Lasse Collin1-16/+8
2009-01-19Fix handling of non-fatal errors in lzma_code().Lasse Collin1-1/+8
2009-01-19Move some LZMA2 constants to lzma2_encoder.h so that theyLasse Collin3-14/+16
can be used outside lzma2_encoder.c.
2009-01-19Remove dead code.Lasse Collin1-8/+0
2009-01-17Beta was supposed to be API stable but I had forgot to renameLasse Collin8-14/+14
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.
2009-01-15Updated THANKS.Lasse Collin1-0/+1
2009-01-15Fixed a bug in 7z2lzma.bash to make it work with .7z filesLasse Collin1-23/+24
that use something else than 2^n as the dictionary size. Thanks to Dan Shechter for the bug report.
2009-01-07Use pthread_sigmask() instead of sigprocmask() when pthreadsLasse Collin3-2/+9
are enabled.
2008-12-31Bumped version to 4.999.8beta right after the releaseLasse Collin2-2/+2
of 4.999.7beta.
2008-12-31Disable Subblock filter from test_compress.sh since it islarhzu/v4.999.7betaLasse Collin1-9/+13
disabled by default in configure.ac.
2008-12-31Disable both Subblock encoder and decoder my default,Lasse Collin1-1/+1
since they are not finished and may have security issues too.
2008-12-31Update some files in debug directory.Lasse Collin3-6/+0
2008-12-31Prepare for 4.999.7beta release.Lasse Collin4-22/+22
2008-12-31Cleaned up some comments in the API headers.Lasse Collin3-14/+15
2008-12-31Renamed lzma_options_simple to lzma_options_bcj in the API.Lasse Collin7-22/+22
The internal implementation is still using the name "simple". It may need some cleanups, so I look at it later.
2008-12-31Fixed missing quoting in configure.ac.Lasse Collin1-19/+19
2008-12-31Updated src/liblzma/Makefile.am to use liblzma.pc.in, whichLasse Collin1-2/+2
should have been in the previous commit.
2008-12-31Remove lzma_init() and other init functions from liblzma API.Lasse Collin37-456/+347
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.
2008-12-27Use 28 MiB as memory usage limit for encoding in test_compress.sh.Lasse Collin1-1/+1
2008-12-27Revert a change made in 3b34851de1eaf358cf9268922fa0eeed8278d680Lasse Collin1-15/+8
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.
2008-12-27Some xz command line tool improvements.Lasse Collin5-44/+121
2008-12-27Bunch of liblzma tweaks, including some API changes.Lasse Collin23-262/+294
The API and ABI should now be very close to stable, although the code behind it isn't yet.
2008-12-18Updated Makefile.am that was missing from the previous commit.Lasse Collin1-1/+0
2008-12-17Remove the alignment functions for now. Maybe they willLasse Collin4-176/+0
be added back in some form later, but the current version wasn't modular, so it would need fixing anyway.
2008-12-17xz message handling improvementsLasse Collin3-14/+146
2008-12-15Fix a dumb bug in .lzma decoder which was introduced inLasse Collin1-15/+14
the previous commit. (Probably the previous commit has other bugs too, it wasn't tested.)
2008-12-15Bunch of liblzma API cleanups and fixes.Lasse Collin27-426/+863
2008-12-15The LZMA2 decoder fix introduced a bug to LZ decoder,Lasse Collin1-10/+23
which made LZ decoder return too early after dictionary reset. This fixes it.
2008-12-15Added two new test files.Lasse Collin3-0/+7
2008-12-15Fix data corruption in LZMA2 decoder.Lasse Collin3-8/+32
2008-12-13Name the package "xz" in configure.ac.Lasse Collin1-7/+4
2008-12-12Some adjustments to GCC warning flags. The important changeLasse Collin1-3/+5
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.
2008-12-10Remove obsolete comment.Lasse Collin1-1/+0
2008-12-10Use "decompression" consistently in --long-help.Lasse Collin1-1/+1
2008-12-10Added preset=NUM to --lzma1 and --lzma2. This makes it easyLasse Collin2-0/+9
to take a preset as a template and modify it a little.
2008-12-09Put the file format specification into the public domain.Lasse Collin1-15/+9
Same will be done to the actual code later.
2008-12-09Make the memusage functions of LZMA1 and LZMA2 encodersLasse Collin3-16/+35
to validate the filter options. Add missing validation to LZMA2 encoder when options are changed in the middle of encoding.
2008-12-09Updated THANKS.Lasse Collin1-0/+1
2008-12-01In command line tool, take advantage of memusage calculation'sLasse Collin1-4/+4
ability to also validate the filter chain and options (not implemented yet for all filters).
2008-12-01Validate the filter chain before checking filter-specificLasse Collin1-4/+10
memory usage.
2008-12-01Make the memusage functions of LZMA1 and LZMA2 decodersLasse Collin3-9/+17
to validate the filter options.
2008-12-01Added the changes for Delta filter that should have beenLasse Collin2-2/+2
part of 656ec87882ee74b192c4ea4a233a235eca7b04d4.
2008-12-01LZMA2 decoder cleanups. Make it require new LZMA propertiesLasse Collin1-54/+41
also in the first LZMA chunk after a dictionary reset in uncompressed chunk.
2008-12-01Added lzma_delta_coder_memusage() which also validatesLasse Collin8-39/+75
the options.
2008-11-29Automake includes the m4 directory, so don't add it inLasse Collin2-1/+1
Makefile.am separately. Updated THANKS.
2008-11-28Tested using COLUMNS environment variable to avoid brokenLasse Collin1-5/+9
progress indicator but since COLUMNS isn't usually available, the code was left commented out.
2008-11-27Cleanups to message.c.Lasse Collin1-29/+18
2008-11-25Remove the nowadays unneeded memory limitting malloc() wrapper.Lasse Collin7-614/+0
2008-11-23VLI encoder and decoder cleanups. Made encoder returnLasse Collin2-13/+33

2008-11-20Support NetBSD's errno for O_NOFOLLOW.Lasse Collin1-0/+8
2008-11-20Build xzdec and lzmadec from xzdec.c. xzdec supports only .xzLasse Collin2-178/+140
files and lzmadec only .lzma files.
2008-11-20Minor cleanups to xzdec.Lasse Collin1-10/+10
2008-11-19Added missing check for uint16_t.Lasse Collin1-0/+1
2008-11-19Renamed lzma to xz and lzmadec to xzdec. We create symlinksLasse Collin28-55/+53
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.
2008-11-19Oh well, big messy commit again. Some highlights:Lasse Collin112-2724/+3240
- 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
2008-10-09Fixed the test that should have been fixed as partLasse Collin1-1/+1

2008-09-10Check for LZMA_FILTER_RESERVED_START in filter_flags_encoder.c.larhzu/v4.999.5alphaLasse Collin1-3/+4
Use LZMA_PROG_ERROR instead of LZMA_HEADER_ERROR if the Filter ID is in the reserved range. This allows Block Header encoder to detect unallowed Filter IDs, which is good for Stream encoder.

2008-09-04Added support for raw encoding and decoding to the commandLasse Collin4-34/+50
line tool, and made various cleanups. --lzma was renamed to --lzma1 to prevent people from accidentally using LZMA when they want LZMA2.

simply nothing that would use it. Allow LZMA_FINISH to the decoders, which will usually ignore it (auto decoder and Stream decoder being exceptions).

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.

from test_block_header.c.
2008-06-18Update the code to mostly match the new simpler file formatLasse Collin109-7965/+4655
specification. Simplify things by removing most of the support for known uncompressed size in most places. There are some miscellaneous changes here and there too. The API of liblzma has got many changes and still some more will be done soon. While most of the code has been updated, some things are not fixed (the command line tool will choke with invalid filter chain, if nothing else). Subblock filter is somewhat broken for now. It will be updated once the encoded format of the Subblock filter has been decided.

2008-06-01Fix a buffer overflow in the LZMA encoder. It was due to myLasse Collin8-620/+532
misunderstanding of the code. There's no tiny fix for this problem, so I also cleaned up the code in general. This reduces the speed of the encoder 2-5 % in the fastest compression mode ("lzma -1"). High compression modes should have no noticeable performance difference. This commit breaks things (especially LZMA_SYNC_FLUSH) but I will fix them once the new format and LZMA2 has been roughly implemented. Plain LZMA won't support LZMA_SYNC_FLUSH at all and won't be supported in the new .lzma format. This may change still but this is what it looks like now. Support for known uncompressed size (that is, LZMA or LZMA2 without EOPM) is likely to go away. This means there will be API changes.
