2009-08-09xzless: Support compressed standard inputJonathan Nieder1-1/+7
It can be somewhat confusing that less < some_file.txt works fine, whereas xzless < some_file.txt.xz does not. Since version 429, ‘less’ allows a filter specified in the LESSOPEN environment variable to preprocess its input even if it comes from standard input, if $LESSOPEN begins with ‘|-’. So set $LESSOPEN to take advantage of this feature. Check less’s version at runtime so xzless can continue to work with older versions.
2009-08-09GPLv2+ not GPLv2 for Doxyfile.in is probably OK.Lasse Collin1-1/+1
2009-08-02Added a copyright notice to Doxyfile.in since it containsLasse Collin1-0/+3
lots of comments from Doxygen. It seems that the Doxygen authors' intent is to not apply their copyright on generated files, but since it doesn't matter for XZ Utils at all, better safe than sorry.

2009-07-14Allow extra commas in filter-specific options on xz command line.Lasse Collin1-0/+7
This may slightly ease writing scripts that construct filter-specific option strings dynamically.
2009-07-14Accept --lzma2=preset=6e where "e" is equivalent to --extremeLasse Collin1-21/+59
when no custom chain is in use.
2009-07-12Add dist-hook to create ChangeLog from the commit log,Lasse Collin1-0/+31
and to conver the man pages to PDF and plain text, which may be convenient to those who cannot render man pages.
2009-07-10BCJ filters: Reject invalid start offsets with LZMA_OPTIONS_ERROR.Lasse Collin8-8/+12
This is a quick and slightly dirty fix to make the code conform to the latest file format specification. Without this patch, it's possible to make corrupt files by specifying start offset that is not a multiple of the filter's alignment. Custom start offset is almost never used, so this was only a minor bug. The xz command line tool doesn't validate the start offset, so one will get a bit unclear error message if trying to use an invalid start offset.
2009-07-10Look for full command names instead of substringsLasse Collin1-9/+13
like "un", "cat", and "lz" when determining if xz is run as unxz, xzcat, lzma, unlzma, or lzcat. This is to ensure that if xz is renamed (e.g. via --program-transform-name), it doesn't so easily work in wrong mode.
2009-07-08Updated THANKS.Lasse Collin1-0/+2
2009-07-08Portability improvement to version.sh.Lasse Collin1-1/+2
2009-07-08Remove --force from xzdec.Lasse Collin2-9/+1
It was ignored for compatibility with xz, but now that --decompress --stdout --force copies unrecognized files as is to stdout, simply ignoring --force in xzdec would be wrong. xzdec will not support copying unrecognized data as is to stdout, so it cannot support --force.
2009-07-06Use sed instead of $(SED) so that we don't need toLasse Collin4-21/+21
use AC_PROG_SED. We don't do anything fancy with sed, so this should work OK. libtool 2.2 sets SED but 1.5 doesn't, so $(SED) happened to work when using libtool 2.2.
2009-07-05Major update to the xzgrep and other scripts based onLasse Collin14-369/+766
the latest versions found from gzip CVS repository. configure will try to find a POSIX shell to be used by the scripts. This should ease portability on systems which have pre-POSIX /bin/sh. xzgrep and xzdiff support .xz, .lzma, .gz, and .bz2 files. xzmore and xzless support only .xz and .lzma files. The name of the xz executable used in these scripts is now correct even if --program-transform-name has been used.
2009-07-05Use @PACKAGE_HOMEPAGE@ in liblzma.pc.in.Lasse Collin1-1/+1
2009-07-04Make "xz --decompress --stdout --force" copy unrecognizedLasse Collin1-35/+178
files as is to standard output. This feature is needed to be more compatible with gzip's behavior. This was more complicated to implement than it sounds, because the way liblzma is able to return errors with files of only a few bytes in size. xz now has its own file type detection code and no longer uses lzma_auto_decoder().
2009-07-02Define PACKAGE_HOMEPAGE in configure.ac and use it inLasse Collin3-4/+9
xz and xzdec. Use also PACKAGE_NAME instead of hardcoding "XZ Utils".
2009-07-01Avoid visibility related compiler warnings on Windows.Lasse Collin1-11/+9
2009-06-30Use static liblzma by default also for tests.Lasse Collin1-1/+4
2009-06-30Build system fixesLasse Collin21-372/+417
Don't use libtool convenience libraries to avoid recently discovered long-standing subtle but somewhat severe bugs in libtool (at least 1.5.22 and 2.2.6 are affected). It was found when porting XZ Utils to Windows <http://lists.gnu.org/archive/html/libtool/2009-06/msg00070.html> but the problem is significant also e.g. on GNU/Linux. Unless --disable-shared is passed to configure, static library built from a set of convenience libraries will contain PIC objects. That is, while libtool builds non-PIC objects too, only PIC objects will be used from the convenience libraries. On 32-bit x86 (tested on mobile XP2400+), using PIC instead of non-PIC makes the decompressor 10 % slower with the default CFLAGS. So while xz was linked against static liblzma by default, it got the slower PIC objects unless --disable-shared was used. I tend develop and benchmark with --disable-shared due to faster build time, so I hadn't noticed the problem in benchmarks earlier. This commit also adds support for building Windows resources into liblzma and executables.

2009-05-22Fix a comment.Lasse Collin1-1/+1
2009-05-22Remove the --info option, which was an alias for --list.Lasse Collin1-1/+0
2009-05-22If xz is run as lzma, unlzma, or lzcat, simply implyLasse Collin1-11/+6
--format=lzma. This means that xz emulating lzma doesn't decompress .xz files, while before this commit it did. The new way is slightly simpler in code and especially in upcoming documentation.
2009-05-22Make the default memory usage limit 40 % of RAM for bothLasse Collin5-88/+82
compressing and decompressing. This should be OK now that xz automatically scales down the compression settings if they would exceed the memory usage limit (earlier, the limit for compression was increased to 90 % because low limit broke scripts that used "xz -9" on systems with low RAM). Support spcifying the memory usage limit as a percentage of RAM (e.g. --memory=50%). Support --threads=0 to reset the thread limit to the default value (number of available CPU cores). Use UINT32_MAX instead of SIZE_MAX as the maximum in args.c. hardware.c was already expecting uint32_t value. Cleaned up the output of --help and --long-help.
2009-05-21Support special value "max" where xz and xzdec accept an integer.Lasse Collin2-1/+9
Don't round the memory usage limit in xzdec --help to avoid an integer overflow and to not give wrong impression that the limit is high enough when it may not actually be.
2009-05-21Install lzdiff, lzgrep, and lzmore as symlinksABCD1-2/+14
This adds lzdiff, lzgrep, and lzmore to the list of symlinks to install. It also installs symlinks for the manual pages and removes the new symlinks on uninstall.
2009-05-02Use a GCC-specific #pragma instead of GCC-specificLasse Collin3-18/+5
-Wno-uninitialized to silence a bogus warning.
2009-05-02Removed --disable-encoder and --disable-decoder. Use the valuesLasse Collin1-40/+8
given to --enable-encoders and --enable-decoders to determine if any encoder or decoder support is wanted.
2009-05-01Remove docs that are too outdated to be updatedLasse Collin5-956/+0
(rewrite will be better).
2009-05-01Added documentation about the legacy .lzma file format.Lasse Collin1-0/+166
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).

2009-02-22Add 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.

2009-02-11Remove 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

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.

2009-02-07Introduced LZMA_API_STATIC macro, which the applicationsLasse Collin2-8/+25

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.

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

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.

2009-01-19Move 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.
