2011-03-31liblzma: Fix decoding of LZMA2 streams having no uncompressed data.Lasse Collin1-4/+4
The decoder considered empty LZMA2 streams to be corrupt. This shouldn't matter much with .xz files, because no encoder creates empty LZMA2 streams in .xz. This bug is more likely to cause problems in applications that use raw LZMA2 streams.
2011-03-24Scripts: Better fix for xzgrep.Lasse Collin1-2/+6
Now it uses "grep -q". Thanks to Gregory Margo.
2011-03-24Updated THANKS.Lasse Collin1-0/+1
2011-03-24Scripts: Fix xzgrep -l.Lasse Collin1-2/+2
It didn't work at all. It tried to use the -q option for grep, but it appended it after "--". This works around it by redirecting to /dev/null. The downside is that this can be slower with big files compared to proper use of "grep -q". Thanks to Gregory Margo.

2011-03-18xz: Add --block-size=SIZE.Lasse Collin4-10/+54
This uses LZMA_FULL_FLUSH every SIZE bytes of input. Man page wasn't updated yet.
2011-03-18xz: Add --single-stream.Lasse Collin4-3/+23
This can be useful when there is garbage after the compressed stream (.xz, .lzma, or raw stream). Man page wasn't updated yet.
2011-02-06xz: Clean up suffix.c.Lasse Collin1-24/+20
struct suffix_pair isn't needed in compresed_name() so get rid of it there.
2011-02-06xz: Check if the file already has custom suffix when compressing.Lasse Collin1-0/+9
Now "xz -S .test foo.test" refuses to compress the file because it already has the suffix .test. The man page had it documented this way already.

xz didn't compress setuid/setgid/sticky files and files with multiple hard links even with --force. This bug was introduced in 23ac2c44c3ac76994825adb7f9a8f719f78b5ee4. Thanks to Charles Wilson.

2010-11-13Simplify paths in generated API docsJonathan Nieder1-1/+1
Currently the file list generated by Doxygen has src/ at the beginning of each path. Paths like common/sysdefs.h and liblzma/api/lzma.h are easier to read without such a prefix. Builds from a separate build directory with mkdir build cd build ../configure doxygen Doxyfile include an even longer prefix /home/someone/src/xz/src; this patch has the nice side-effect of eliminating that prefix, too.

2010-10-26Build: Copy the example programs to $docdir/examples.Lasse Collin2-1/+7
The example programs by Daniel Mealha Cabrita were included in the git repository, but I had forgot to add them to Makefile.am. Thus, they didn't get included in the source package at all by "make dist".
2010-10-26liblzma: Rename a few variables and constants.Lasse Collin8-186/+183
This has no semantic changes. I find the new names slightly more logical and they match the names that are already used in XZ Embedded. The name fastpos wasn't changed (not worth the hassle).

2010-10-23liblzma: Make lzma_code() check the reserved members in lzma_stream.Lasse Collin1-0/+14
If any of the reserved members in lzma_stream are non-zero or non-NULL, LZMA_OPTIONS_ERROR is returned. It is possible that a new feature in the future is indicated by just setting a reserved member to some other value, so the old liblzma version need to catch it as an unsupported feature.
2010-10-23Windows: Use MinGW's stdio functions.Lasse Collin1-0/+5
The non-standard ones from msvcrt.dll appear to work most of the time with XZ Utils, but there are some corner cases where things may go very wrong. So it's good to use the better replacements provided by MinGW(-w64) runtime.
2010-10-23liblzma: Use 512 as INDEX_GROUP_SIZE.Lasse Collin1-1/+1

2010-10-12xz: Avoid raise() also on OpenVMS.Lasse Collin1-1/+1
This is similar to DOS/DJGPP that killing the program with a signal will print a backtrace or a similar message.
2010-10-11xz: Avoid SA_RESTART for portability reasons.Lasse Collin3-23/+25
SA_RESTART is not as portable as I had hoped. It's missing at least from OpenVMS, QNX, and DJGPP). Luckily we can do fine without SA_RESTART.

2010-10-09OS/2 and DOS: Be less verbose on signals.Lasse Collin1-0/+7
Calling raise() to kill xz when user has pressed C-c is a bit verbose on OS/2 and DOS/DJGPP. Instead of calling raise(), set only the exit status to 1.

2010-10-09Windows: Make build.bash prefer MinGW-w32 over MinGW.Lasse Collin1-9/+9
This is simply for licensing reasons. The 64-bit version will be built with MinGW-w64 anyway (at least for now), so using it also for 32-bit build allows using the same copyright notice about the MinGW-w64/w32 runtime. Note that using MinGW would require a copyright notice too, because its runtime is not in the public domain either even though MinGW's home page claims that it is public domain. See <http://marc.info/?l=mingw-users&m=126489506214078>.

2010-10-08Use LZMA_VERSION_STRING instead of PACKAGE_VERSION.Lasse Collin1-1/+1
Those are the same thing, and the former makes it a bit easier to build the code with other build systems, because one doesn't need to update the version number into custom config.h. This change affects only lzmainfo. Other tools were already using LZMA_VERSION_STRING.

2010-10-05Build: Remove the static/dynamic tricks.Lasse Collin6-91/+5
Most distros want xz linked against shared liblzma, so it doesn't help much to require --enable-dynamic for that. Those who want to avoid PIC on x86-32 to get better performance, can still do it e.g. by using --disable-shared to compile xz and then another pass to compile shared liblzma. Part of these static/dynamic tricks were needed for Windows in the past. Nowadays we rely on GCC and binutils to do the right thing with auto-import. If the Autotooled build system needs to support some other toolchain on Windows in the future, this may need some rethinking.

2010-09-10xz: Add a comment to translators about "literal context bits".Lasse Collin1-0/+4
2010-09-10xz: Multiple fixes.Lasse Collin12-187/+424
The code assumed that printing numbers with thousand separators and decimal points would always produce only US-ASCII characters. This was used for buffer sizes (with snprintf(), no overflows) and aligning columns of the progress indicator and --list. That assumption was wrong (e.g. LC_ALL=fi_FI.UTF-8 with glibc), so multibyte character support was added in this commit. The old way is used if the operating system doesn't have enough multibyte support (e.g. lacks wcwidth()). The sizes of buffers were increased to accomodate multibyte characters. I don't know how big they should be exactly, but they aren't used for anything critical, so it's not too bad. If they still aren't big enough, I hopefully get a bug report. snprintf() takes care of avoiding buffer overflows. Some static buffers were replaced with buffers allocated on stack. double_to_str() was removed. uint64_to_str() and uint64_to_nicestr() now share the static buffer and test for thousand separator support. Integrity check names "None" and "Unknown-N" (2 <= N <= 15) were marked to be translated. I had forgot these, plus they wouldn't have worked correctly anyway before this commit, because printing tables with multibyte strings didn't work. Thanks to Marek Černocký for reporting the bug about misaligned table columns in --list output.

"Extreme" mode might need some further tweaking still. Docs were not updated yet.
2010-09-03liblzma: Adjust default depth calculation for HC3 and HC4.Lasse Collin1-3/+4
It was 8 + nice_len / 4, now it is 4 + nice_len / 4. This allows faster settings at lower nice_len values, even though it seems that I won't use automatic depth calcuation with HC3 and HC4 in the presets.
2010-09-03xz: Make --help two lines shorter.Lasse Collin1-2/+5
At least for now, the --help option doesn't list any options that take arguments, so "Mandatory arguments to..." can be omitted.
2010-09-02xz: Make setting a preset override a custom filter chain.Lasse Collin1-0/+9
This is more logical behavior than ignoring preset level options once a custom filter chain has been specified.

2010-08-10Fix test_compress.sh.Lasse Collin1-3/+3
It broke when --memory option was removed from xzdec. Thanks to Jonathan Nieder.
2010-08-07Disable the memory usage limiter by default.Lasse Collin10-448/+373
For several people, the limiter causes bigger problems that it solves, so it is better to have it disabled by default. Those who want to have a limiter by default need to enable it via the environment variable XZ_DEFAULTS. Support for environment variable XZ_DEFAULTS was added. It is parsed before XZ_OPT and technically identical with it. The intended uses differ quite a bit though; see the man page. The memory usage limit can now be set separately for compression and decompression using --memlimit-compress and --memlimit-decompress. To set both at once, -M or --memlimit can be used. --memory was retained as a legacy alias for --memlimit for backwards compatibility. The semantics of --info-memory were changed in backwards incompatible way. Compatibility wasn't meaningful due to changes in the memory usage limiter functionality. The memory usage limiter info is no longer shown at the bottom of xz --long -help. The memory usage limiter support for removed completely from xzdec. xz's man page was updated to match the above changes. Various unrelated fixes were also made to the man page.

When using -O2 with GCC, it liked to swap two comparisons in one "if" statement.

A few people find this annoying so do things a bit differently to avoid the warning.

2010-05-16Split message_filters().Lasse Collin3-69/+134
message_filters_to_str() converts the filter chain to a string. message_filters_show() replaces the original message_filters(). uint32_to_optstr() was also added to show the dictionary size in nicer format when possible.

2010-05-10Updates to tuklib_physmem and tuklib_cpucores.Lasse Collin4-11/+141
Don't use #error to generate compile error, because some compilers actually don't take it as an error. This fixes tuklib_physmem on IRIX. Fix incorrect error check for sysconf() return values. Add AIX, HP-UX, and Tru64 specific code to detect the amount RAM. Add HP-UX specific code to detect the number of CPU cores. Thanks a lot to Peter O'Gorman for initial patches, testing, and debugging these fixes.
2010-04-12Show both elapsed time and estimated remaining time in xz -v.Lasse Collin2-48/+39
The extra space for showing both has been taken from the sizes field. If the sizes grow big, bigger units than MiB will be used. It makes it slightly difficult to see that progress is still happening with huge files, but it should be OK in practice. Thanks to Trent W. Buck for <http://bugs.debian.org/574583> and Jonathan Nieder for suggestions how to fix it.

Thanks to someone who reported the bug on IRC.
2010-03-07Treat all integer multiplier suffixes as base-2.Lasse Collin3-76/+67
Originally both base-2 and base-10 were supported, but since there seems to be little need for base-10 in XZ Utils, treat everything as base-2 and also be more relaxed about the case of the first letter of the suffix. Now xz will accept e.g. KiB, Ki, k, K, kB, and KB, and interpret them all as 1024. The recommended spelling of the suffixes are still KiB, MiB, and GiB.
2010-03-07Consistently round up the memory usage limit in messages.Lasse Collin2-4/+8
It still feels a bit wrong to round 1 byte to 1 MiB but at least it is now done consistently so that the same byte value is always rounded the same way to MiB.
2010-03-07Change the default of --enable-assume-ram from 32 to 128 MiB.Lasse Collin2-8/+8
This is to allow files created with "xz -9" to be decompressed if the amount of RAM cannot be determined.
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.

2010-01-31Revise 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.

2010-01-31Don'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.

2010-01-17Updated 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).

2010-01-13Don'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.

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>
