2010-01-13Don't read compressed data from a terminal or write itLasse Collin2-15/+13
to a terminal even if --force is specified. It just seems more reasonable this way. The new behavior matches bzip2. The old one matched gzip.
2010-01-13Don't compress or decompress special files unless writingLasse Collin1-5/+10
to stdout even if --force is used. --force will still enable compression of symlinks, but only in case they point to a regular file. The new way simply seems more reasonable. It matches gzip's behavior while the old one matched bzip2's behavior.
2009-12-07Fix file_io.c on DOS-like systems.Lasse Collin1-0/+4
The problem was introduced when adding sparse file support in 465d1b0d6518c5d980f2db4c2d769f9905bdd902. Thanks to Charles Wilson.
2009-12-07Add a note for translators to add a bug reporting addressLasse Collin1-0/+4
for translation bugs.
2009-12-07Prevent xgettext from taking one regular string as a C format string.Lasse Collin1-1/+1
Thanks to Marek Černocký.
2009-11-28Remove duplicate code in io_open_dest().Lasse Collin1-8/+1
Fix a missing _() in the error message too.
2009-11-25Add missing error check to coder.c.Lasse Collin1-9/+11
With bad luck this could cause a segfault due to reading (but not writing) past the end of the buffer.
2009-11-25Create sparse files by default when decompressing intoLasse Collin6-56/+272
a regular file. Sparse file creation can be disabled with --no-sparse. I don't promise yet that the name of this option won't change before 5.0.0. It's possible that the code, that checks when it is safe to use sparse output on stdout, is not good enough, and a more flexible command line option is needed to configure sparse file handling.
2009-11-16Add support for --info-memory and --robot to xz.Lasse Collin6-55/+133
Currently --robot works only with --info-memory and --version. --help and --long-help work too, but --robot has no effect on them. Thanks to Jonathan Nieder for the original patches.
2009-11-15Add lzma_physmem().Lasse Collin2-3/+1
I had hoped to keep liblzma as purely a compression library as possible (e.g. file I/O will go into a different library), but it seems that applications linking agaisnt liblzma need some way to determine the memory usage limit, and knowing the amount of RAM is one reasonable way to help making such decisions. Thanks to Jonathan Nieder for the original patch.
2009-11-14Some updates to xz man page.Lasse Collin1-5/+49
2009-11-14Fix description of --memory in --long-help.Lasse Collin1-2/+1
2009-11-14Fix a design error in liblzma API.Lasse Collin1-1/+0
Originally the idea was that using LZMA_FULL_FLUSH with Stream encoder would read the filter chain from the same array that was used to intialize the Stream encoder. Since most apps wouldn't use LZMA_FULL_FLUSH, most apps wouldn't need to keep the filter chain available after initializing the Stream encoder. However, due to my mistake, it actually required keeping the array always available. Since setting the new filter chain via the array used at initialization time is not a nice way to do it for a couple of reasons, this commit ditches it and introduces lzma_filters_update(). This new function replaces also the "persistent" flag used by LZMA2 (and to-be-designed Subblock filter), which was also an ugly thing to do. Thanks to Alexey Tourbin for reminding me about the problem that Stream encoder used to require keeping the filter chain allocated.
2009-10-16Mention --check=none in --long-help. It was already inLasse Collin1-1/+1
the man page though. Thanks to Jim Meyering for noticing this.
2009-10-02Add support for --enable-assume-ram=SIZE.Lasse Collin1-4/+3
2009-09-24Fix an error in OpenVMS-specific code.Lasse Collin1-1/+1
Thanks to Jouk Jansen.
2009-09-22Better fixes for OpenVMS support.Lasse Collin1-3/+16
Thanks to Jouk Jansen.
2009-09-19Various changes.Lasse Collin12-155/+88
Separate a few reusable components from XZ Utils specific code. The reusable code is now in "tuklib" modules. A few more could be separated still, e.g. bswap.h. Fix some bugs in lzmainfo. Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol for help. Add OpenVMS support into physmem. Add a few #ifdefs to ease building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the original patch.
2009-09-12A few grammar fixes.Lasse Collin1-11/+11
Thanks to Christian Weisgerber for pointing out some of these.
2009-09-11Use $(LN_EXEEXT) in symlinks to executables.Lasse Collin1-2/+2
This fixes "make install" on operating systems using a suffix for executables. Cygwin is treated specially. The symlink names won't have .exe suffix even though the executables themselves have. Thanks to Charles Wilson.
2009-09-01Refactored option parsing.Lasse Collin1-35/+35
2009-09-01Fix options parsing bug in xz.Lasse Collin1-4/+2
xz used to reject "xz --lzma2=pb=2," while "xz --lzma2=pb=2,," worked. Now both work.
2009-08-29Use even more hackish way to support thousand separators.Lasse Collin1-11/+25
Seems that in addition on Windows and DOS, also OpenBSD lacks support for %'d style printf() format strings. So far that is the only modern POSIX-like system I know with this problem, but after this hack, the thousand separator shouldn't be a problem on any system. Maybe testing if a format string like %'d produces reasonable output is invoking undefined behavior on some systems, but so far all the problematic systems I've tried just print the raw format string (e.g. %'d prints 'd). Maybe Autoconf test would have been better, but this hack works also for cross-compilation, and avoids recompilation in case the system libc starts to support the thousand separator.

2009-07-18Added public domain notice into a few files.Lasse Collin1-0/+7
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.
2009-07-10Look 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.
2009-07-06Use sed instead of $(SED) so that we don't need toLasse Collin1-3/+3
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.
2009-07-04Make "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 Collin1-2/+2
xz and xzdec. Use also PACKAGE_NAME instead of hardcoding "XZ Utils".
2009-06-30Build system fixesLasse Collin1-1/+10
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.
2009-06-27Moved the Windows resource files outside the windows directoryLasse Collin1-0/+5
to prepare for building them with Autotools.

Fix the ordering of libgnu.a and LTLIBINTL on the linker command line and added missing LTLIBINTL to tests/Makefile.am.

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 Collin1-0/+4
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.
2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin23-230/+69
Some minor documentation cleanups were made at the same time.
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.
2009-02-14Fix microsecond vs. nanosecond confusion in my_time().Lasse Collin1-1/+1
2009-02-14Cleanups to the code that detects the amount of RAM andLasse Collin5-35/+37
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.
2009-02-13Changed how the version number is specified in various places.Lasse Collin1-1/+1
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 Collin5-22/+61

2009-02-08Support both slash and backslash as path componentLasse Collin1-0/+9
separator on Windows when parsing argv[0].
2009-02-07Make it easy to choose if command line tools should beLasse Collin1-5/+3
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.
2009-02-05Various code cleanups the the xz command line tool.Lasse Collin17-246/+386
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.
2009-01-31Add LZMA_API to liblzma API headers. It's useful at leastLasse Collin1-0/+1
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h has to be #included separately where needed.
2009-01-17Beta was supposed to be API stable but I had forgot to renameLasse Collin1-3/+3
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.
2009-01-07Use pthread_sigmask() instead of sigprocmask() when pthreadsLasse Collin2-2/+3
are enabled.
2008-12-31Remove lzma_init() and other init functions from liblzma API.Lasse Collin2-7/+1
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.
