2010-03-07Increase the default memory usage limit on "low-memory" systems.Lasse Collin4-34/+80
Previously the default limit was always 40 % of RAM. The new limit is a little bit more complex: - If 40 % of RAM is at least 80 MiB, 40 % of RAM is used as the limit. - If 80 % of RAM is over 80 MiB, 80 MiB is used as the limit. - Otherwise 80 % of RAM is used as the limit. This should make it possible to decompress files created with "xz -9" on more systems. Swapping is generally more expected on systems with less RAM, so higher default limit on them shouldn't cause too bad surprises in terms of heavy swapping. Instead, the higher default limit should reduce the number of bad surprises when it used to prevent decompression of files created with "xz -9". The DoS prevention system shouldn't be a DoS itself. Note that even with the new default limit, a system with 64 MiB RAM cannot decompress files created with "xz -9" without user overriding the limit. This should be OK, because if xz is going to need more memory than the system has RAM, it will run very very slowly and thus it's good that user has to override the limit in that case.

2010-03-06Fix missing initialization in lzma_strm_init().Lasse Collin1-0/+1
With bad luck, lzma_code() could return LZMA_BUF_ERROR when it shouldn't. This has been here since the early days of liblzma. It got triggered by the modifications made to the xz tool in commit 18c10c30d2833f394cd7bce0e6a821044b15832f but only when decompressing .lzma files. Somehow I managed to miss testing that with Valgrind earlier. This fixes <http://bugs.gentoo.org/show_bug.cgi?id=305591>. Thanks to Rafał Mużyło for helping to debug it on IRC.

2010-02-07Subtle change to liblzma Block handling API.Lasse Collin2-22/+20
lzma_block.version has to be initialized even for lzma_block_header_decode(). This way a future version of liblzma won't allocate memory in a way that an old application doesn't know how to free it. The subtlety of this change is that all current apps using lzma_block_header_decode() will keep working for now, because the only possible version value is zero, and lzma_block_header_decode() unconditionally sets the version to zero even now. Unless fixed, these apps will break in the future if a new version of the Block options is ever needed.

2010-01-31Updated INSTALL.Lasse Collin1-26/+26
2010-01-31Revise the Windows build files.Lasse Collin6-645/+435
The old Makefile + config.h was deleted, because it becomes outdated too easily and building with the Autotools based build system works fine even on Windows. windows/build.sh hasn't got much testing, but it should work to build 32-bit x86 and x86-64 versions of XZ Utils using MSYS, MinGW or MinGW-w32, and MinGW-w64. windows/INSTALL-Windows.txt describes what packages are needed and how to install them. windows/README-Windows.txt is a readme file for the binary package that build.sh hopefully builds. There are no instructions about using Autotools for now, so those using a git snapshot may want to run "autoreconf -fi && ./configure && make mydist" on a UN*X box and then copy the resulting .tar.gz to a Windows.
2010-01-31Select the default integrity check type at runtime.Lasse Collin1-5/+14
Previously it was set statically to CRC64 or CRC32 depending on options passed to the configure script.
2010-01-31Improve displaying of the memory usage limit.Lasse Collin4-13/+45
2010-01-31Don't use uninitialized sigset_t.Lasse Collin1-10/+24
If signal handlers haven't been established, then it's useless to try to block them, especially since the sigset_t used for blocking hasn't been initialized yet.
2010-01-31Delay opening the destionation file and other fixes.Lasse Collin6-125/+157
The opening of the destination file is now delayed a little. The coder is initialized, and if decompressing, the memory usage of the first Block compared against the memory usage limit before the destination file is opened. This means that if --force was used, the old "target" file won't be deleted so easily when something goes wrong very early. Thanks to Mark K for the bug report. The above fix required some changes to progress message handling. Now there is a separate function for setting and printing the filename. It is used also in list.c. list_file() now handles stdin correctly (gives an error). A useless check for user_abort was removed from file_io.c.

2010-01-24Add initial version of xz --list.Lasse Collin5-359/+668
This is a bit rough but should be useful for basic things. Ideas (with detailed examples) about the output format are welcome. The output of --robot --list is not necessarily stable yet, although I don't currently have any plans about changing it. The man page hasn't been updated yet.
2010-01-24Add io_pread().Lasse Collin2-0/+42
It will be used by --list.
2010-01-24Set LC_NUMERIC=C when --robot is used.Lasse Collin1-0/+4

2010-01-17Updated windows/Makefile.Lasse Collin2-13/+27
Thanks to Dan Shechter for the patch. It is likely that windows/Makefile will be removed completely, because Autotols based build nowadays works well with both 32-bit and 64-bit MinGW (I just need to update the docs).
2010-01-15Update the xz man page to match the previous two commits.Lasse Collin1-6/+3
2010-01-13Don't read compressed data from a terminal or write itLasse Collin2-15/+13

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.

2010-01-12Add IRIX-specific code to tuklib_physmem and tuklib_cpucores.Lasse Collin4-3/+55

2010-01-01Fix _memconfig() functions.Lasse Collin4-19/+20
This affects lzma_memusage() and lzma_memlimit_get().
2009-12-31Revised the Index handling code.Lasse Collin9-858/+1703
This breaks API and ABI but most apps are not affected since most apps don't use this part of the API. You will get a compile error if you are using anything that got broken. Summary of changes: - Ability to store Stream Flags, which are needed for random-access reading in multi-Stream files. - Separate function to set size of Stream Padding. - Iterator structure makes it possible to read the same lzma_index from multiple threads at the same time. - A lot faster code to locate Blocks. - Removed lzma_index_equal() without adding anything to replace it. I don't know what it should do exactly with the new features and what actually needs this function in the first place other than test_index.c, which now has its own code to compare lzma_indexes.

2009-12-09update po/.gitignoreJonathan Nieder1-6/+22
Since the *.gmo files are deleted by the maintainer-clean target, I assume they are not meant to be tracked. Also add the other files listed in the Makefile’s clean targets (stamp-poT, xz.po, xz.[12].po, *.new.po, xz.mo) to make sure they are not accidentally tracked. Most of these are intermediate files that would not appear unless a build is interrupted or fails. Split the list of untracked files by origin to make it easier to tell if files are missing in the future. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>

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.
2009-11-25Fix bugs in lzma_index_read() and lzma_index_cat().Lasse Collin2-14/+44
lzma_index_read() didn't skip over Stream Padding if it was the first record in the Index. lzma_index_cat() didn't combine small Indexes correctly. The test suite was updated to check for these bugs. These bugs didn't affect the xz command line tool or most users of liblzma in any way.
2009-11-25Index decoder fixes.Lasse Collin2-17/+32
The Index decoder code didn't perfectly match the API docs, which said that *i will be set to point to the decoded Index only after decoding has succeeded. The docs were a bit unclear too. Now the decoder will initially set *i to NULL. *i will be set to point to the decoded Index once decoding has succeeded. This simplifies applications too, since it avoids dangling pointers.
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.

2009-11-22Enable assembler code only if it is known to workLasse Collin1-14/+12
on that operating system. I'm too lazy to think how to make a good Autoconf test for this and it's not that important anyway. No longer define HAVE_ASM_X86 or HAVE_ASM_X86_64. Inline assembler (if any) is used if a macro like __i386__ or __x86_64__ is defined.

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 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.

2009-11-14Fix 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

2009-10-04Use a tuklib module for integer handling.Lasse Collin28-333/+467
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.

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. ;-)

2009-08-29Use 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.

This is quite messy compared to how simple thing it is supposed to be. The complexity is mostly due to Windows support.
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 Collin5-1/+328
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.

Make xz error message translation usable outside xz (at least in upcoming lzmainfo).

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.

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.

2009-07-10BCJ 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.

2009-07-08Portability 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".

2009-06-30Build 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.
