2011-10-23liblzma: Fix invalid free() in the threaded encoder.Lasse Collin1-0/+4
It was triggered if initialization failed e.g. due to running out of memory. Thanks to Arkadiusz Miskiewicz.
2011-10-23liblzma: Fix a deadlock in the threaded encoder.Lasse Collin1-1/+3
It was triggered when reinitializing the encoder, e.g. when encoding two files.
2011-09-06Build: Fix "make check" on Windows.Lasse Collin2-2/+7
2011-08-09Update THANKS.Lasse Collin1-0/+2
2011-08-09Workaround unusual SIZE_MAX on SCO OpenServer.Lasse Collin1-3/+6
2011-08-06Run the scripts with the correct shell in test_scripts.sh.Lasse Collin2-8/+8
The scripts are now made executable in the build tree. This way the scripts can be run like programs in test_scripts.sh. Previously test_scripts.sh always used sh but it's not correct if @POSIX_SHELL@ is set to something else by configure. Thanks to Jonathan Nieder for the patch.
2011-07-31Fix exit status of "xzdiff foo.xz bar.xz".Lasse Collin3-1/+59
xzdiff was clobbering the exit status from diff in a case statement used to analyze the exit statuses from "xz" when its operands were two compressed files. Save and restore diff's exit status to fix this. The bug is inherited from zdiff in GNU gzip and was fixed there on 2009-10-09. Thanks to Jonathan Nieder for the patch and to Peter Pallinger for reporting the bug.
2011-06-16liblzma: Remove unneeded semicolon.Lasse Collin1-1/+1
2011-05-28Build: Make configure print if symbol versioning is enabled or not.Lasse Collin1-0/+2
2011-05-28Don't call close(-1) in tuklib_open_stdxxx() on error.Lasse Collin1-1/+3
Thanks to Jim Meyering.
2011-05-28liblzma: Use symbol versioning.Lasse Collin5-0/+201
Symbol versioning is enabled by default on GNU/Linux, other GNU-based systems, and FreeBSD. I'm not sure how stable this is, so it may need backward-incompatible changes before the next release. The idea is that alpha and beta symbols are considered unstable and require recompiling the applications that use those symbols. Once a symbol is stable, it may get extended with new features in ways that don't break compatibility with older ABI & API. The mydist target runs validate_map.sh which should catch some probable problems in liblzma.map. Otherwise I would forget to update the map file for new releases.
2011-05-28Translations: Update the Italian translation.Lasse Collin1-149/+216
Thanks to Milo Casagrande.
2011-05-28Tests: Add a test file for the bug in the previous commit.Lasse Collin2-0/+4
2011-05-27xz: Fix error handling in xz -lvv.Lasse Collin1-15/+6
It could do an invalid free() and read past the end of the uninitialized filters array.
2011-05-27liblzma: Handle allocation failures correctly in lzma_index_init().Lasse Collin1-2/+5
Thanks to Jim Meyering.
2011-05-24Build: Fix checking for system-provided SHA-256.Lasse Collin1-1/+1
2011-05-23Build: Set GZIP_ENV=-9n in top-level Makefile.am.Lasse Collin1-0/+3
2011-05-22Update NEWS for 5.0.3.Lasse Collin1-0/+32
2011-05-21Add French translation.Lasse Collin2-0/+865
It is known that the BCJ filter --help text is only partially translated.
2011-05-21xz: Translate also the string used to print the program name.Lasse Collin1-1/+5
French needs a space before a colon, e.g. "xz : foo error".
2011-05-21liblzma: Try to use SHA-256 from the operating system.Lasse Collin3-8/+131
If the operating system libc or other base libraries provide SHA-256, use that instead of our own copy. Note that this doesn't use OpenSSL or libgcrypt or such libraries to avoid creating dependencies to other packages. This supports at least FreeBSD, NetBSD, OpenBSD, Solaris, MINIX, and Darwin. They all provide similar but not identical SHA-256 APIs; everyone is a little different. Thanks to Wim Lewis for the original patch, improvements, and testing.
2011-05-17Don't use clockid_t in mythread.h when clock_gettime() isn't available.Lasse Collin1-0/+2
Thanks to Wim Lewis for the patch.
2011-05-17Update THANKS.Lasse Collin1-0/+3
2011-05-17Update INSTALL with a note about linker problem on OpenSolaris x86.Lasse Collin1-6/+17
2011-05-17Build: Fix initialization of enable_check_* variables in configure.ac.Lasse Collin1-1/+1
This doesn't matter much in practice since it is unlikely that anyone would have such environment variable names. Thanks to Wim Lewis.
2011-05-17Add underscores to attributes (__attribute((__foo__))).Lasse Collin25-47/+49
2011-05-01xz: Fix input file position when --single-stream is used.Lasse Collin3-0/+29
Now the following works as you would expect: echo foo | xz > foo.xz echo bar | xz >> foo.xz ( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz Note that it doesn't work if the input is not seekable or if there is Stream Padding between the concatenated .xz Streams.
2011-05-01xz: Print the maximum number of worker threads in xz -vv.Lasse Collin1-0/+4
2011-04-19Build: Warn if no supported method to detect the number of CPU cores.Lasse Collin1-6/+5
2011-04-19Update THANKS.Lasse Collin1-0/+1
2011-04-19Fix portability problems in mythread.h.Lasse Collin2-4/+34
Use gettimeofday() if clock_gettime() isn't available (e.g. Darwin). The test for availability of pthread_condattr_setclock() and CLOCK_MONOTONIC was incorrect. Instead of fixing the #ifdefs, use an Autoconf test. That way if there exists a system that supports them but doesn't specify the matching POSIX #defines, the features will still get detected. Don't try to use pthread_sigmask() on OpenVMS. It doesn't have that function. Guard mythread.h against being #included multiple times.

2011-04-12Put the unstable APIs behind #ifdef LZMA_UNSTABLE.Lasse Collin3-0/+8
This way people hopefully won't complain if these APIs change and break code that used an older API.

2011-04-12Update NEWS.Lasse Collin1-2/+45
2011-04-12Update TODO.Lasse Collin1-1/+11
2011-04-12xz: Update the man page about threading.Lasse Collin1-14/+20
2011-04-11xz: Add support for threaded compression.Lasse Collin2-80/+125
2011-04-11liblzma: Add lzma_stream_encoder_mt() for threaded compression.Lasse Collin8-1/+1539
This is the simplest method to do threading, which splits the uncompressed data into blocks and compresses them independently from each other. There's room for improvement especially to reduce the memory usage, but nevertheless, this is a good start.
2011-04-11liblzma: Add the forgotten lzma_lzma2_block_size().Lasse Collin2-0/+12
This should have been in 5eefc0086d24a65e136352f8c1d19cefb0cbac7a.
2011-04-11liblzma: Document lzma_easy_(enc|dec)oder_memusage() better too.Lasse Collin1-0/+9
2011-04-11liblzma: Document lzma_raw_(enc|dec)oder_memusage() better.Lasse Collin1-2/+6
It didn't mention the return value that is used if an error occurs.
2011-04-11liblzma: Use memzero() to initialize supported_actions[].Lasse Collin1-4/+2
This is cleaner and makes it simpler to add new members to lzma_action enumeration.
2011-04-11liblzma: API comment about lzma_allocator with threaded coding.Lasse Collin1-5/+13
2011-04-11liblzma: Add an internal function lzma_mt_block_size().Lasse Collin2-26/+24
This is based lzma_chunk_size() that was included in some development version of liblzma.
2011-04-11liblzma: Don't create an empty Block in lzma_stream_buffer_encode().Lasse Collin1-7/+13
Empty Block was created if the input buffer was empty. Empty Block wastes a few bytes of space, but more importantly it triggers a bug in XZ Utils 5.0.1 and older when trying to decompress such a file. 5.0.1 and older consider such files to be corrupt. I thought that no encoder creates empty Blocks when releasing 5.0.2 but I was wrong.
2011-04-11liblzma: Fix API docs to mention LZMA_UNSUPPORTED_CHECK.Lasse Collin2-0/+4
This return value was missing from the API comments of four functions.
2011-04-11liblzma: Validate encoder arguments better.Lasse Collin3-6/+20
The biggest problem was that the integrity check type wasn't validated, and e.g. lzma_easy_buffer_encode() would create a corrupt .xz Stream if given an unsupported Check ID. Luckily applications don't usually try to use an unsupport Check ID, so this bug is unlikely to cause many real-world problems.
2011-04-11xz: Move the description of --block-size in --long-help.Lasse Collin1-4/+4
2011-04-11Docs: Document --single-stream and --block-size.Lasse Collin1-2/+36
2011-04-11liblzma: Make lzma_stream_encoder_init() static (second try).Lasse Collin4-32/+6
It's an internal function and it's not needed by anything outside stream_encoder.c.
2011-04-11Revert "liblzma: Make lzma_stream_encoder_init() static."Lasse Collin3-4/+29
This reverts commit 352ac82db5d3f64585c07b39e4759388dec0e4d7. I don't know what I was thinking.
2011-04-10Revise mythread.h.Lasse Collin2-20/+181
This adds: - mythread_sync() macro to create synchronized blocks - mythread_cond structure and related functions and macros for condition variables with timed waiting using a relative timeout - mythread_create() to create a thread with all signals blocked Some of these wouldn't need to be inline functions, but I'll keep them this way for now for simplicity. For timed waiting on a condition variable, librt is now required on some systems to use clock_gettime(). configure.ac was updated to handle this.
2011-04-10liblzma: Make lzma_stream_encoder_init() static.Lasse Collin3-29/+4
It's an internal function and it's not needed by anything outside stream_encoder.c.
2011-04-10DOS: Update the docs and include notes about 8.3 filenames.Lasse Collin2-11/+125
2011-04-10xz/DOS: Add experimental 8.3 filename support.Lasse Collin1-9/+167
This is incompatible with the 8.3 support patch made by Juan Manuel Guerrero. I think this one is nicer, but I need to get feedback from DOS users before saying that this is the final version of 8.3 filename support.
2011-04-10xz/DOS: Be more careful with the destination file.Lasse Collin1-2/+33
Try to avoid overwriting the source file if --force is used and the generated destination filename refers to the source file. This can happen with 8.3 filenames where extra characters are ignored. If the generated output file refers to a special file like "con" or "prn", refuse to write to it even if --force is used.
2011-04-09Update THANKS.Lasse Collin1-0/+1
2011-04-09liblzma: Add missing #ifdefs to filter_common.c.Lasse Collin1-3/+3
Passing --disable-decoders to configure broke a few encoders due to missing #ifdefs in filter_common.c. Thanks to Jason Gorski for the patch.
2011-04-09xz: Avoid unneeded fstat() on DOS-like systems.Lasse Collin1-6/+8
2011-04-09xz: Minor internal changes to handling of --threads.Lasse Collin3-19/+18
Now it always defaults to one thread. Maybe this will change again if a threading method is added that doesn't affect memory usage.
2011-04-08xz: Change size_t to uint32_t in a few places.Lasse Collin2-4/+4
2011-04-08xz: Fix a typo in a comment.Lasse Collin1-1/+1

2011-04-05Build: Upgrade m4/acx_pthread.m4 to the latest version.Lasse Collin2-84/+88
It was renamed to ax_pthread.m4 in Autoconf Archive.
2011-04-05xz: Use posix_fadvise() if it is available.Lasse Collin2-0/+18
2011-04-05xz: Call lzma_end(&strm) before exiting if debugging is enabled.Lasse Collin3-0/+19
2011-04-02liblzma: Fix a memory leak in stream_encoder.c.Lasse Collin1-1/+1
It leaks old filter options structures (hundred bytes or so) every time the lzma_stream is reinitialized. With the xz tool, this happens when compressing multiple files.
2011-04-01Updated NEWS for 5.0.2.Lasse Collin1-0/+18
2011-03-31Update INSTALL with another note about IRIX.Lasse Collin1-0/+4
2011-03-31Tests: Add a new file to test empty LZMA2 streams.Lasse Collin2-0/+4
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.
2011-03-19Scripts: Add lzop (.lzo) support to xzdiff and xzgrep.Lasse Collin4-16/+28
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.

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: 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.

2010-09-07Fix use of N_() and ngettext().Lasse Collin2-4/+4
I had somehow thought that N_() is usually used as shorthand for ngettext(). This also fixes a missing \n from a call to ngettext().

2010-09-04Don't set lc=4 with --extreme.Lasse Collin1-1/+0
This should reduce the cases where --extreme makes compression worse. On the other hand, some other files may now benefit slightly less from --extreme.
2010-09-04xz: Minor improvements to --help and --long-help.Lasse Collin1-12/+12
2010-09-04Adjust memory limits in test_compress.shJonathan Nieder1-1/+1
Testing compression at level -4 now requires 48 MiB of free store at compression time and 5 MiB at decompression time. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>
2010-09-03xz: Make -vv show also decompressor memory usage.Lasse Collin1-0/+7
2010-09-03Tweak the compression presets -0 .. -5.Lasse Collin1-10/+19
"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.
2010-09-02xz: Always warn if adjusting dictionary size due to memlimit.Lasse Collin1-19/+9
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.

Hopefully these help a bit when learning the basics of liblzma API. I plan to write detailed examples about both basic and advanced features with lots of comments, but these two examples are good have right now. The examples were written by Daniel Mealha Cabrita. Thanks.

2010-06-02Silence a bogus Valgrind warning.Lasse Collin1-1/+5
When using -O2 with GCC, it liked to swap two comparisons in one "if" statement. It's otherwise fine except that the latter part, which is seemingly never executed, got executed (nothing wrong with that) and then triggered warning in Valgrind about conditional jump depending on uninitialized variable. A few people find this annoying so do things a bit differently to avoid the warning.
