2009-11-15Add lzma_physmem().Lasse Collin10-11/+88
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 Collin20-118/+273
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.
2009-10-17Fix wrong function name in the previous commit.Lasse Collin2-2/+2
It was meant to be lzma_filters_copy(), not lzma_filters_dup().
2009-10-17Add lzma_filters_copy().Lasse Collin2-0/+113
This will be needed internally by liblzma once I fix a design mistake in the encoder API. This function may be useful to applications too so it's good to export it.
2009-10-16Escape dashes in xzmore.1Jonathan Nieder1-2/+2
A minus sign is larger, easier to see in a printout, and more likely to use the same glyph as ASCII hyphen-minus in a terminal than a hyphen. Since broken manual pagers do not find hyphens when the user searches for a hyphen-minus, minus signs are also easier to search for. So use minus signs instead of hyphens to render sample terminal output.
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.
2009-10-04Use a tuklib module for integer handling.Lasse Collin23-274/+386
This replaces bswap.h and integer.h. The tuklib module uses <byteswap.h> on GNU, <sys/endian.h> on *BSDs and <sys/byteorder.h> on Solaris, which may contain optimized code like inline assembly.
2009-10-02Add support for --enable-assume-ram=SIZE.Lasse Collin2-6/+6
2009-10-02Use unaligned access (if possible) on both endiannessesLasse Collin1-2/+2
in lz_encoder_hash.h.
2009-10-02Make liblzma produce the same output on both endiannesses.Lasse Collin6-14/+128
Seems that it is a problem in some cases if the same version of XZ Utils produces different output on different endiannesses, so this commit fixes that problem. The output will still vary between different XZ Utils versions, but I cannot avoid that for now. This commit bloatens the code on big endian systems by 1 KiB, which should be OK since liblzma is bloated already. ;-)
2009-09-27Work around a bug in Interix header files.Lasse Collin1-0/+6
Thanks to Markus Duft for the patch.
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.
2009-09-22Avoid non-standard preprocessor construct.Lasse Collin1-4/+7
Thanks to Jouk Jansen.
2009-09-21Make sure that TUKLIB_DOSLIKE doesn't get defined on Cygwin.Lasse Collin1-1/+2
Thanks to Charles Wilson.
2009-09-19Various changes.Lasse Collin30-308/+548
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.
2009-09-15Fix incorrect use of "restrict".Lasse Collin3-4/+4
2009-09-12Fix GCC version check for nothrow attribute.Lasse Collin1-1/+1
2009-09-12A few grammar fixes.Lasse Collin7-23/+23
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.
2009-09-11Fix a couple of warnings.Lasse Collin4-10/+7
2009-09-05Add OS/2-specific code to physmem.h.Lasse Collin1-11/+21
Also move DJGPP-specific code near the code meant for other DOS-like systems.
2009-09-05Use sysctl() != -1 instead of !sysctl() to check ifLasse Collin2-2/+2
the function call succeeded. NetBSD 4.0 returns positive values on success, but NetBSD Current and FreeBSD return zero. OpenBSD's man page doesn't tell what sysctl() returns on success. All these BSDs return -1 on error. Thanks to Robert Elz and Thomas Klausner.
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.
2009-08-31Revert 43f44160b1ddcbf7e5205c37db09b3bebe7226f9Lasse Collin2-10/+4
and use a fix that works on all systems using GNU assembler. Maybe the assembler code is used e.g. on Solaris x86 but let's worry about it if this doesn't work on it.
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.
2009-08-29Fix sysctl() usage.Lasse Collin2-2/+2
This fixes build on *BSDs and Darwin. Thanks to Jukka Salmi for the patches. Richard Koch reported the problem too.
2009-08-29Fix x86 assembler on GCC 3.Lasse Collin2-4/+10
Thanks to Karl Berry.
2009-08-27Update xz man page date.Lasse Collin1-1/+1
2009-08-27Bumped version to 4.999.9beta.Lasse Collin1-1/+1
2009-08-27Some xz man page improvements.Lasse Collin1-16/+62
2009-08-27Updates to liblzma API headers.Lasse Collin12-197/+275
Added lzma_nothrow for every function. It adds throw() when the header is used in C++ code. Some lzma_attrs were added or removed. Lots of comments were improved.
2009-08-17Some xz man changes.Lasse Collin1-45/+43
2009-08-16Fix data corruption in LZ/LZMA2 encoder.Lasse Collin1-1/+1
Thanks to Jonathan Stott for the bug report.
2009-08-13Link lzmainfo against shared liblzma by default.Lasse Collin1-2/+2
2009-08-13Fix xz Makefile.am for the man page.Lasse Collin1-0/+2
install-exec-hook -> install-data-hook
2009-08-13Add lzmainfo for backward compatibility with LZMA Utils.Lasse Collin4-1/+327
lzmainfo now links against static liblzma. In contrast to other command line tools in XZ Utils, linking lzmainfo against static liblzma by default is dumb. This will be fixed once I have fixed some related issues in configure.ac.
2009-08-13Sync some error messages from xz to xzdec.Lasse Collin2-5/+5
Make xz error message translation usable outside xz (at least in upcoming lzmainfo).
2009-08-13Fix first line of xz man page.Lasse Collin1-1/+1
2009-08-10Added a rough version of the xz man page.Lasse Collin2-0/+1221
2009-08-09“xzdiff a.xz b.xz” always failsJonathan Nieder1-1/+1
Attempts to compare two compressed files result in no output and exit status 2. Instead of going to standard output, ‘diff’ output is being captured in the xz_status variable along with the exit status from the decompression commands. Later, when this variable is examined for nonzero status codes, numerals from dates in the ‘diff’ output make it appear as though decompression failed. So let the ‘diff’ output leak to standard output with another file descriptor. (This trick is used in all similar contexts elsewhere in xzdiff and in the analogous context in gzip’s zdiff script.)
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.
2009-07-30xzdiff: add missing ;; to case statementJonathan Nieder1-3/+3
2009-07-23Fix incorrect usage of getopt_long(), which causedLasse Collin1-1/+0
invalid memory access if XZ_OPT was defined.
2009-07-20Avoid internal error with --format=xz --lzma1.Lasse Collin1-4/+12
2009-07-19Added missing author notice to xzless.in.Lasse Collin1-0/+1
2009-07-18Added public domain notice into a few files.Lasse Collin5-1/+36
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.
2009-07-10BCJ 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.
2009-07-08Remove --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 Collin12-369/+689
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 Collin2-4/+4
xz and xzdec. Use also PACKAGE_NAME instead of hardcoding "XZ Utils".
2009-06-30Build system fixesLasse Collin20-361/+394
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.

the Autotools based build system. It's not good yet, more fixes will follow.
2009-06-26Fix @variables@ to $(variables) in Makefile.am files.Lasse Collin10-44/+46
Fix the ordering of libgnu.a and LTLIBINTL on the linker command line and added missing LTLIBINTL to tests/Makefile.am.

minor cleanups.
2009-06-04Fix purporse -> purpose. Thanks to Andrew Dudman.Lasse Collin1-1/+1
Released .xz spec 1.0.2 due to this fix too.
2009-05-26Make the raw value of the Check field available to applicationsLasse Collin4-31/+42
via lzma_block structure. This changes ABI but not doesn't break API.
2009-05-23Remove undocumented alternative option names --bcj, --ppc,Lasse Collin1-3/+0
and --itanium.
2009-05-23Add support for specifying the BCJ filter start offsetLasse Collin4-21/+76
in the xz command line tool.
2009-05-22Added support for --quiet and --no-warn to xzdec.Lasse Collin1-27/+49
Cleaned up the --help message a little.
2009-05-22Use the 40 % of RAM memory usage limit in xzdec too.Lasse Collin1-5/+5
Update the memory usage info text in --help to match the text in xz --long-help.

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 Collin2-5/+5
-Wno-uninitialized to silence a bogus warning.
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).
2009-04-13Quick & 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 Collin177-1750/+723
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.
2009-03-18Fix wrong macro names in lc_cpucores.m4 and cpucores.h.Lasse Collin1-2/+2
Thanks to Bert Wesarg.
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 Collin6-47/+175
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 Collin7-43/+102
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 Collin4-6/+70
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.
2009-02-09Let the user specify custom CFLAGS on the make commandLasse Collin1-1/+1
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].
2009-02-07Make it easy to choose if command line tools should beLasse Collin2-7/+6
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.
2009-02-07Support 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.
2009-02-05Various 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 Collin2-22/+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.

2009-01-31Add LZMA_API to liblzma API headers. It's useful at leastLasse Collin16-88/+130
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h has to be #included separately where needed.

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

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.

2009-01-25Fix 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.

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.
2009-01-07Use pthread_sigmask() instead of sigprocmask() when pthreadsLasse Collin3-2/+9
are enabled.
2008-12-31Bumped version to 4.999.8beta right after the releaseLasse Collin1-1/+1
of 4.999.7beta.
2008-12-31Prepare for 4.999.7beta release.Lasse Collin1-1/+1
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 Collin6-18/+18
The internal implementation is still using the name "simple". It may need some cleanups, so I look at it later.
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 Collin30-441/+322
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.
2008-12-27Revert 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

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.
2008-11-28Tested 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.

2008-11-20Build 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
2008-11-19Renamed lzma to xz and lzmadec to xzdec. We create symlinksLasse Collin24-24/+26
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 Collin50-2258/+2963
- 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
