2014-12-21Update NEWS for 5.0.8.Lasse Collin1-0/+12
2014-12-21xz: Fix a comment.Lasse Collin1-2/+2
2014-12-20Update INSTALL about the dependencies of the scripts.Lasse Collin1-5/+10
2014-12-20Windows: Update build instructions.Lasse Collin2-29/+30
2014-12-20Windows: Update the build script and README-Windows.txt.Lasse Collin2-23/+30
The 32-bit build is now for i686 or newer because the prebuilt MinGW-w64 toolchains include i686 code in the executables even if one uses -march=i486. The build script builds 32-bit SSE2 enabled version too. Run-time detection of SSE2 support would be nice (on any OS) but it's not implemented in XZ Utils yet.
2014-12-19Windows: Define TUKLIB_SYMBOL_PREFIX in config.h.Lasse Collin1-0/+3
It is to keep all symbols in the lzma_ namespace.
2014-12-16xz: Update the man page about --threads.Lasse Collin1-5/+0
2014-12-16xz: Update the man page about --block-size.Lasse Collin1-8/+33
2014-12-12po/fr: several more translation updates: reword and handle --ignore-check.Adrien Nader1-24/+26
2014-12-12po/fr: yet another place where my email address had to be updated.Adrien Nader1-1/+1
2014-12-12po/fr: fix several typos that have been around since the beginning.Adrien Nader1-11/+11
2014-12-12po/fr: last batch of new translations for now.Adrien Nader1-8/+8
Four new error messages.
2014-12-12po/fr: translations for --threads, --block-size and --block-list.Adrien Nader1-4/+8
2014-12-12po/fr: remove fuzzy marker for error messages that will be kept in English.Adrien Nader1-6/+16
The following is a copy of a comment inside fr.po: Note from translator on "file status flags". The following entry is kept un-translated on purpose. It is difficult to translate and should only happen in exceptional circumstances which means that translating would: - lose some of the meaning - make it more difficult to look up in search engines; it might happen one in a million times, if we dilute the error message in 20 languages, it will be almost impossible to find an explanation and support for the error.
2014-12-12po/fr: several minor updates and better wording.Adrien Nader1-7/+7
Meaning doesn't change at all: it's only for better wording and/or formatting of a few strings.
2014-12-12po/fr: update my email address and copyright years.Adrien Nader1-2/+2
2014-12-12fr.po: commit file after only "update-po" so actual is readable.Adrien Nader1-112/+199
2014-12-02liblzma: Document how lzma_mt.block_size affects memory usage.Lasse Collin1-0/+4
2014-11-28Update INSTALL about a "make check" failure in test_scripts.sh.Lasse Collin1-7/+17
2014-11-26Remove LZMA_UNSTABLE macro.Lasse Collin3-7/+0
2014-11-26liblzma: Update lzma_stream_encoder_mt() API docs.Lasse Collin1-2/+3
2014-11-25liblzma: Verify the filter chain in threaded encoder initialization.Lasse Collin1-3/+6
This way an invalid filter chain is detected at the Stream encoder initialization instead of delaying it to the first call to lzma_code() which triggers the initialization of the actual filter encoder(s).
2014-11-17Build: Update m4/ax_pthread.m4 from Autoconf Archive.Lasse Collin1-24/+47
2014-11-17Build: Replace obsolete AC_HELP_STRING with AS_HELP_STRING.Lasse Collin2-19/+19
2014-11-17Build: Fix Autoconf warnings about escaped backquotes.Lasse Collin1-4/+3
Thanks to Daniel Richard G. for pointing out that it's good to sometimes run autoreconf -fi with -Wall.
2014-11-10xzdiff: Use mkdir if mktemp isn't available.Lasse Collin1-1/+16
2014-11-10xzdiff: Create a temporary directory to hold a temporary file.Lasse Collin1-5/+5
This avoids the possibility of "File name too long" when creating a temp file when the input file name is very long. This also means that other users on the system can no longer see the input file names in /tmp (or whatever $TMPDIR is) since the temporary directory will have a generic name. This usually doesn't matter since on many systems one can see the arguments given to all processes anyway. The number X chars to mktemp where increased from 6 to 10. Note that with some shells temp files or dirs won't be used at all.
2014-11-10liblzma: Fix lzma_mt.preset in lzma_stream_encoder_mt_memusage().Lasse Collin1-2/+1
It read the filter chain from a wrong variable. This is a similar bug that was fixed in 9494fb6d0ff41c585326f00aa8f7fe58f8106a5e.
2014-11-10Update THANKS.Lasse Collin1-0/+1
2014-10-29Update .gitignore files.Lasse Collin2-0/+5
2014-10-29Build: Prepare to support Automake's subdir-objects.Lasse Collin6-15/+40
Due to a bug in Automake, subdir-objects won't be enabled for now. http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17354 Thanks to Daniel Richard G. for the original patches.

2014-10-14l10n: de.po: Change translator email address.Andre Noll1-3/+3
Although the old address is still working, the new one should be preferred. So this commit changes all three places in de.po accordingly. Signed-off-by: Andre Noll <maan@tuebingen.mpg.de>

2014-10-09Add support for AmigaOS/AROS to tuklib_physmem().Lasse Collin2-1/+9
Thanks to Fredrik Wikstrom.
2014-10-09xzgrep: Avoid passing both -q and -l to grep.Lasse Collin1-2/+4
The behavior of grep -ql varies: - GNU grep behaves like grep -q. - OpenBSD grep behaves like grep -l. POSIX doesn't make it 100 % clear what behavior is expected. Anyway, using both -q and -l at the same time makes no sense so both options simply should never be used at the same time. Thanks to Christian Weisgerber.

2014-09-25Build: Detect supported compiler warning flags better.Lasse Collin1-2/+3
Clang and nowadays also GCC accept any -Wfoobar option but then may give a warning that an unknown warning option was specified. To avoid adding unsupported warning options, the options are now tested with -Werror. Thanks to Charles Diza.
2014-09-20Update NEWS for 5.0.7.Lasse Collin1-0/+11
2014-09-20liblzma: Fix a portability problem in Makefile.am.Lasse Collin1-1/+1
POSIX supports $< only in inference rules (suffix rules). Using it elsewhere is a GNU make extension and doesn't work e.g. with OpenBSD make. Thanks to Christian Weisgerber for the patch.
2014-09-14Bump the version number to 5.1.4beta.larhzu/v5.1.4betaLasse Collin2-3/+3
2014-09-14Update NEWS for 5.0.6 and 5.1.4beta.Lasse Collin1-0/+50
2014-09-14Update TODO.Lasse Collin1-4/+34
2014-08-05xz: Add --ignore-check.Lasse Collin5-1/+38
2014-08-05liblzma: Add support for LZMA_IGNORE_CHECK.Lasse Collin3-2/+37
2014-08-05liblzma: Add support for lzma_block.ignore_check.Lasse Collin7-20/+68
Note that this slightly changes how lzma_block_header_decode() has been documented. Earlier it said that the .version is set to the lowest required value, but now it says that the .version field is kept unchanged if possible. In practice this doesn't affect any old code, because before this commit the only possible .version was 0.
2014-08-04liblzma: Use lzma_memcmplen() in the BT3 match finder.Lasse Collin1-3/+2
I had missed this when writing the commit 5db75054e900fa06ef5ade5f2c21dffdd5d16141. Thanks to Jun I Jin.
2014-08-04Update THANKS.Lasse Collin1-0/+1
2014-08-03liblzma: SHA-256: Optimize the Maj macro slightly.Lasse Collin1-1/+1
The Maj macro is used where multiple things are added together, so making Maj a sum of two expressions allows some extra freedom for the compiler to schedule the instructions. I learned this trick from <http://www.hackersdelight.org/corres.txt>.
2014-08-03liblzma: SHA-256: Optimize the way rotations are done.Lasse Collin1-6/+11
This looks weird because the rotations become sequential, but it helps quite a bit on both 32-bit and 64-bit x86: - It requires fewer instructions on two-operand instruction sets like x86. - It requires one register less which matters especially on 32-bit x86. I hope this doesn't hurt other archs. I didn't invent this idea myself, but I don't remember where I saw it first.
2014-08-03liblzma: SHA-256: Remove the GCC #pragma that became unneeded.Lasse Collin1-5/+0
The unrolling in the previous commit should avoid the situation where a compiler may think that an uninitialized variable might be accessed.
2014-08-03liblzma: SHA-256: Unroll a little more.Lasse Collin1-9/+16
This way a branch isn't needed for each operation to choose between blk0 and blk2, and still the code doesn't grow as much as it would with full unrolling.
2014-08-03liblzma: SHA-256: Do the byteswapping without a temporary buffer.Lasse Collin1-12/+1
2014-07-25liblzma: Use lzma_memcmplen() in normal mode of LZMA.Lasse Collin1-15/+5
Two locations were not changed yet because the simplest change assumes that the initial "len" may be greater than "limit".
2014-07-25liblzma: Simplify LZMA fast mode code by using memcmp().Lasse Collin1-10/+1
2014-07-25liblzma: Use lzma_memcmplen() in fast mode of LZMA.Lasse Collin1-3/+3

2014-07-25liblzma: Use lzma_memcmplen() in the match finders.Lasse Collin2-23/+23
This doesn't change the match finder output.
2014-07-25liblzma: Add lzma_memcmplen() for fast memory comparison.Lasse Collin3-0/+184
This commit just adds the function. Its uses will be in separate commits. This hasn't been tested much yet and it's perhaps a bit early to commit it but if there are bugs they should get found quite quickly. Thanks to Jun I Jin from Intel for help and for pointing out that string comparison needs to be optimized in liblzma.

2014-06-18xz: Check for filter chain compatibility for --flush-timeout.Lasse Collin1-9/+21
This avoids LZMA_PROG_ERROR from lzma_code() with filter chains that don't support LZMA_SYNC_FLUSH.
2014-06-13xzgrep: List xzgrep_expected_output in tests/Makefile.am.Lasse Collin1-1/+2
2014-06-13xzgrep: Improve the test script.Lasse Collin3-11/+55
Now it should be close to the functionality of the original version by Pavel Raiskup.
2014-06-11xzgrep: Add a test for the previous fix.Lasse Collin1-4/+22
This is a simplified version of Pavel Raiskup's original patch.
2014-06-11xzgrep: exit 0 when at least one file matches.Lasse Collin1-2/+13
Mimic the original grep behavior and return exit_success when at least one xz compressed file matches given pattern. Original bugreport: https://bugzilla.redhat.com/show_bug.cgi?id=1108085 Thanks to Pavel Raiskup for the patch.
2014-06-09xz: Force single-threaded mode when --flush-timeout is used.Lasse Collin1-0/+11
2014-05-25Update THANKS.Lasse Collin1-0/+1
2014-05-25liblzma: Use lzma_alloc_zero() in LZ encoder initialization.Lasse Collin3-55/+62
This avoids a memzero() call for a newly-allocated memory, which can be expensive when encoding small streams with an over-sized dictionary. To avoid using lzma_alloc_zero() for memory that doesn't need to be zeroed, lzma_mf.son is now allocated separately, which requires handling it separately in normalize() too. Thanks to Vincenzo Innocente for reporting the problem.
2014-05-25liblzma: Add the internal function lzma_alloc_zero().Lasse Collin2-0/+27
2014-05-08xz: Fix uint64_t vs. size_t which broke 32-bit build.Lasse Collin1-1/+1
Thanks to Christian Hesse.
2014-05-04Docs: Update comments to refer to lzma/lzma12.h in example programs.Lasse Collin1-3/+3
2014-05-04liblzma: Rename the private API header lzma/lzma.h to lzma/lzma12.h.Lasse Collin3-3/+3
It can be confusing that two header files have the same name. The public API file is still lzma.h.
2014-04-25Build: Fix the combination of --disable-xzdec --enable-lzmadec.Lasse Collin1-1/+9
In this case "make install" could fail if the man page directory didn't already exist at the destination. If it did exist, a dangling symlink was created there. Now the link is omitted instead. This isn't the best fix but it's better than the old behavior.
2014-04-25Build: Add --disable-doc to configure.Lasse Collin3-0/+14
2014-04-24Update INSTALL.Lasse Collin1-0/+25
Add a note about failing "make check". The source of the problem should be fixed in libtool (if it really is a libtool bug and not mine) but I'm unable to spend time on that for now. Thanks to Nelson H. F. Beebe for reporting the issue. Add a note about a possible need to run "ldconfig" after "make install".
2014-04-09xz: Rename a variable to avoid a namespace collision on Solaris.Lasse Collin1-5/+7
I don't know the details but I have an impression that there's no problem in practice if using GCC since people have built xz with GCC (without patching xz), but renaming the variable cannot hurt either. Thanks to Mark Ashley.
2014-01-29Docs: Add example program for threaded encoding.Lasse Collin2-1/+186
I didn't add -DLZMA_UNSTABLE to Makefile so one has to specify it manually as long as LZMA_UNSTABLE is needed.
2014-01-29liblzma: Fix lzma_mt.preset not working with lzma_stream_encoder_mt().Lasse Collin1-2/+2
It read the filter chain from a wrong variable.
2014-01-20liblzma: Fix typo in a comment.Lasse Collin1-1/+1
2014-01-12Windows: Add config.h for building liblzma with MSVC 2013.Lasse Collin1-0/+139
This is for building liblzma. Building xz tool too requires a little more work. Maybe it will be supported, but for most MSVC users it's enough to be able to build liblzma. C99 support in MSVC 2013 is almost usable which is a big improvement over earlier versions. It's "almost" because there's a dumb bug that breaks mixed declarations after an "if" statements unless the "if" statement uses braces: https://connect.microsoft.com/VisualStudio/feedback/details/808650/visual-studio-2013-c99-compiler-bug https://connect.microsoft.com/VisualStudio/feedback/details/808472/c99-support-of-mixed-declarations-and-statements-fails-with-certain-types-and-constructs Hopefully it will get fixed. Then liblzma should be compilable with MSVC 2013 without patching.
2014-01-12xz: Fix a comment.Lasse Collin1-2/+2
2014-01-12Windows: Add MSVC defines for inline and restrict keywords.Lasse Collin1-0/+10
2014-01-12liblzma: Avoid C99 compound literal arrays.Lasse Collin1-3/+5
MSVC 2013 doesn't like them. Maybe they aren't so good for readability either since many aren't used to them.
2014-01-12liblzma: Remove a useless C99ism from sha256.c.Lasse Collin1-1/+1
Unsurprisingly it makes no difference in compiled output.
2014-01-12xz: Fix use of wrong variable.Lasse Collin1-1/+1
Since the only call to suffix_set() uses optarg as the argument, fixing this bug doesn't change the behavior of the program.

2013-11-26Update THANKS.Lasse Collin1-0/+1
2013-11-26liblzma: Document the need for block->check for lzma_block_header_decode().Lasse Collin1-0/+3
Thanks to Tomer Chachamu.
2013-11-12xz: Update the man page about --block-size and --block-list.Lasse Collin1-9/+15
2013-11-12Update THANKS.Lasse Collin1-0/+1
2013-11-12xz: Make --block-list and --block-size work together in single-threaded.Lasse Collin1-15/+75
Previously, --block-list and --block-size only worked together in threaded mode. Boundaries are specified by --block-list, but --block-size specifies the maximum size for a Block. Now this works in single-threaded mode too. Thanks to James M Leddy for the original patch.
2013-10-26Bump the version number to 5.1.3alpha.larhzu/v5.1.3alphaLasse Collin2-2/+2
2013-10-26Update NEWS for 5.1.3alpha.Lasse Collin1-0/+35
2013-10-26Update TODO.Lasse Collin1-4/+0
2013-10-25xz: Document behavior of --block-list with threads.Lasse Collin1-3/+21
This needs to be updated before 5.2.0.
2013-10-22xz: Document --flush-timeout=TIMEOUT on the man page.Lasse Collin1-1/+36
2013-10-22xz: Take advantage of LZMA_FULL_BARRIER with --block-list.Lasse Collin1-17/+15
Now if --block-list is used in threaded mode, the encoder won't need to flush at each Block boundary specified via --block-list. This improves performance a lot, making threading helpful with --block-list. The flush timer was reset after LZMA_FULL_FLUSH but since LZMA_FULL_BARRIER doesn't flush, resetting the timer is no longer done.
2013-10-02liblzma: Support LZMA_FULL_FLUSH and _BARRIER in threaded encoder.Lasse Collin1-16/+39
Now --block-list=SIZES works with in the threaded mode too, although the performance is still bad due to the use of LZMA_FULL_FLUSH instead of the new LZMA_FULL_BARRIER.
2013-10-02liblzma: Add LZMA_FULL_BARRIER support to single-threaded encoder.Lasse Collin4-11/+54
In the single-threaded encoder LZMA_FULL_BARRIER is simply an alias for LZMA_FULL_FLUSH.
2013-09-17liblzma: Add block_buffer_encoder.h into Makefile.inc.Lasse Collin1-0/+1
This should have been in b465da5988dd59ad98fda10c2e4ea13d0b9c73bc.
2013-09-17xz: Add a missing test for TUKLIB_DOSLIKE.Lasse Collin1-0/+2
2013-09-17Add native threading support on Windows.Lasse Collin7-215/+573
Now liblzma only uses "mythread" functions and types which are defined in mythread.h matching the desired threading method. Before Windows Vista, there is no direct equivalent to pthread condition variables. Since this package doesn't use pthread_cond_broadcast(), pre-Vista threading can still be kept quite simple. The pre-Vista code doesn't use anything that wasn't already available in Windows 95, so the binaries should run even on Windows 95 if someone happens to care.
2013-09-11Build: Remove a comment about Automake 1.10 from configure.ac.Lasse Collin1-2/+0
The previous commit supports silent rules and that requires Automake 1.11.
2013-09-09Build: Create liblzma.pc in a src/liblzma/Makefile.am.Lasse Collin2-1/+20
Previously it was done in configure, but doing that goes against the Autoconf manual. Autoconf requires that it is possible to override e.g. prefix after running configure and that doesn't work correctly if liblzma.pc is created by configure. A potential downside of this change is that now e.g. libdir in liblzma.pc is a standalone string instead of being defined via ${prefix}, so if one overrides prefix when running pkg-config the libdir won't get the new value. I don't know if this matters in practice. Thanks to Vincent Torri.
2013-08-04Fix the previous commit which broke the build.Lasse Collin1-1/+1
Apparently I didn't even compile-test the previous commit. Thanks to Christian Hesse.

2013-07-15Build: Fix the detection of missing CRC32.Lasse Collin1-1/+1
Thanks to Vincent Torri.
2013-07-04xz: Add preliminary support for --flush-timeout=TIMEOUT.Lasse Collin3-21/+78
When --flush-timeout=TIMEOUT is used, xz will use LZMA_SYNC_FLUSH if read() would block and at least TIMEOUT milliseconds has elapsed since the previous flush. This can be useful in realtime-like use cases where the data is simultanously decompressed by another process (possibly on a different computer). If new uncompressed input data is produced slowly, without this option xz could buffer the data for a long time until it would become decompressible from the output. If TIMEOUT is 0, the feature is disabled. This is the default. This commit affects the compression side. Using xz for the decompression side for the above purpose doesn't work yet so well because there is quite a bit of input and output buffering when decompressing. The --long-help or man page were not updated yet. The details of this feature may change.
2013-07-04xz: Don't set src_eof=true after an I/O error because it's useless.Lasse Collin1-3/+0
2013-07-04xz: Fix the test when to read more input.Lasse Collin1-3/+3
Testing for end of file was no longer correct after full flushing became possible with --block-size=SIZE and --block-list=SIZES. There was no bug in practice though because xz just made a few unneeded zero-byte reads.
2013-07-04xz: Move some of the timing code into mytime.[hc].Lasse Collin6-40/+158
This switches units from microseconds to milliseconds. New clock_gettime(CLOCK_MONOTONIC) will be used if available. There is still a fallback to gettimeofday().

2013-06-30Update NEWS for 5.0.5.Lasse Collin1-0/+52
2013-06-30Man pages: Use similar syntax for synopsis as in xz.Lasse Collin3-10/+10
The man pages of lzmainfo, xzmore, and xzdec had similar constructs as the man page of xz had before the commit eb6ca9854b8eb9fbf72497c1cf608d6b19d2d494. Eric S. Raymond didn't mention these man pages in his bug report, but it's nice to be consistent.
2013-06-29xz: Use non-blocking I/O for the output file.Lasse Collin1-8/+49
Now both reading and writing should be without race conditions with signals. They might still be signal handling issues left. Signals are blocked during many operations to avoid EINTR but it may cause problems e.g. if writing to stderr blocks when trying to display an error message.
2013-06-28xz: Fix return value type in io_write_buf().Lasse Collin1-1/+1
It didn't affect the behavior of the code since -1 becomes true anyway.
2013-06-28xz: Use the self-pipe trick to avoid a race condition with signals.Lasse Collin3-12/+57
It is possible that a signal to set user_abort arrives right before a blocking system call is made. In this case the call may block until another signal arrives, while the wanted behavior is to make xz clean up and exit as soon as possible. After this commit, the race condition is avoided with the input side which already uses non-blocking I/O. The output side still uses blocking I/O and thus has the race condition.
2013-06-28xz: Use non-blocking I/O for the input file.Lasse Collin1-45/+111
2013-06-28xz: Remove an outdated NetBSD-specific comment.Lasse Collin1-4/+0
Nowadays errno == EFTYPE is documented in open(2).
2013-06-28xz: Fix error detection of fcntl(fd, F_SETFL, flags) calls.Lasse Collin1-4/+4
POSIX says that fcntl(fd, F_SETFL, flags) returns -1 on error and "other than -1" on success. This is how it is documented e.g. on OpenBSD too. On Linux, success with F_SETFL is always 0 (at least accorinding to fcntl(2) from man-pages 3.51).
2013-06-28xz: Fix use of wrong variable in a fcntl() call.Lasse Collin1-11/+13
Due to a wrong variable name, when writing a sparse file to standard output, *all* file status flags were cleared (to the extent the operating system allowed it) instead of only clearing the O_APPEND flag. In practice this worked fine in the common situations on GNU/Linux, but I didn't check how it behaved elsewhere. The original flags were still restored correctly. I still changed the code to use a separate boolean variable to indicate when the flags should be restored instead of relying on a special value in stdout_flags.
2013-06-28xz: Fix assertion related to posix_fadvise().Lasse Collin1-8/+2
Input file can be a FIFO or something else that doesn't support posix_fadvise() so don't check the return value even with an assertion. Nothing bad happens if the call to posix_fadvise() fails.
2013-06-26xz: Check the value of lzma_stream_flags.version in --list.Lasse Collin1-0/+14
It is a no-op for now, but if an old xz version is used together with a newer liblzma that supports something new, then this check becomes important and will stop the old xz from trying to parse files that it won't understand.
2013-06-26Build: Require Automake 1.12 and use serial-tests option.Lasse Collin1-1/+3
It should actually still work with Automake 1.10 if the serial-tests option is removed. Automake 1.13 started using parallel tests by default and the option to get the old behavior isn't supported before 1.12. At least for now, parallel tests don't improve anything in XZ Utils but they hide the progress output from test_compress.sh.

2013-06-23xz: Validate Uncompressed Size from Block Header in list.c.Lasse Collin1-1/+13
This affects only "xz -lvv". Normal decompression with xz already detected if Block Header and Index had mismatched Uncompressed Size fields. So this just makes "xz -lvv" show such files as corrupt instead of showing the Uncompressed Size from Index.

2013-06-21xz: Fix interaction between preset and custom filter chains.Lasse Collin1-14/+21
There was somewhat illogical behavior when --extreme was specified and mixed with custom filter chains. Before this commit, "xz -9 --lzma2 -e" was equivalent to "xz --lzma2". After it is equivalent to "xz -6e" (all earlier preset options get forgotten when a custom filter chain is specified and the default preset is 6 to which -e is applied). I find this less illogical. This also affects the meaning of "xz -9e --lzma2 -7". Earlier it was equivalent to "xz -7e" (the -e specified before a custom filter chain wasn't forgotten). Now it is "xz -7". Note that "xz -7e" still is the same as "xz -e7". Hopefully very few cared about this in the first place, so pretty much no one should even notice this change. Thanks to Conley Moorhous.
2013-04-27Build: Use -Wvla with GCC if supported.Lasse Collin1-0/+1
Variable-length arrays are mandatory in C99 but optional in C11. The code doesn't currently use any VLAs and it shouldn't in the future either to stay compatible with C11 without requiring any optional C11 features.
2013-04-15xzdec: Improve the --help message.Lasse Collin1-5/+5
The options are now ordered in the same order as in xz's help message. Descriptions were added to the options that are ignored. I left them in parenthesis even if it looks a bit weird because I find it easier to spot the ignored vs. non-ignored options from the list that way.

2013-03-23liblzma: Be less picky in lzma_alone_decoder().Lasse Collin3-11/+18
To avoid false positives when detecting .lzma files, rare values in dictionary size and uncompressed size fields were rejected. They will still be rejected if .lzma files are decoded with lzma_auto_decoder(), but when using lzma_alone_decoder() directly, such files will now be accepted. Hopefully this is an OK compromise. This doesn't affect xz because xz still has its own file format detection code. This does affect lzmadec though. So after this commit lzmadec will accept files that xz or xz-emulating-lzma doesn't. NOTE: lzma_alone_decoder() still won't decode all .lzma files because liblzma's LZMA decoder doesn't support lc + lp > 4.

2013-03-23liblzma: Use lzma_block_buffer_bound64() in threaded encoder.Lasse Collin1-16/+50
Now it uses lzma_block_uncomp_encode() if the data doesn't fit into the space calculated by lzma_block_buffer_bound64().
2013-03-23liblzma: Fix another deadlock in the threaded encoder.Lasse Collin1-3/+6
This race condition could cause a deadlock if lzma_end() was called before finishing the encoding. This can happen with xz with debugging enabled (non-debugging version doesn't call lzma_end() before exiting).
2013-03-23liblzma: Add lzma_block_uncomp_encode().Lasse Collin4-31/+106
This also adds a new internal function lzma_block_buffer_bound64() which is similar to lzma_block_buffer_bound() but uses uint64_t instead of size_t.
2013-03-05Avoid unneeded use of awk in xzless.Lasse Collin1-2/+1
Use "read" instead of "awk" in xzless to get the version number of "less". The need for awk was introduced in the commit db5c1817fabf7cbb9e4087b1576eb26f0747338e. Thanks to Ariel P for the patch.
2012-12-14Make the progress indicator smooth in threaded mode.Lasse Collin6-13/+129
This adds lzma_get_progress() to liblzma and takes advantage of it in xz. lzma_get_progress() collects progress information from the thread-specific structures so that fairly accurate progress information is available to applications. Adding a new function seemed to be a better way than making the information directly available in lzma_stream (like total_in and total_out are) because collecting the information requires locking mutexes. It's waste of time to do it more often than the up to date information is actually needed by an application.

2012-11-21xzless: Make "less -V" parsing more robustJonathan Nieder1-1/+2
In v4.999.9beta~30 (xzless: Support compressed standard input, 2009-08-09), xzless learned to parse ‘less -V’ output to figure out whether less is new enough to handle $LESSOPEN settings starting with “|-”. That worked well for a while, but the version string from ‘less’ versions 448 (June, 2012) is misparsed, producing a warning: $ xzless /tmp/test.xz; echo $? /usr/bin/xzless: line 49: test: 456 (GNU regular expressions): \ integer expression expected 0 More precisely, modern ‘less’ lists the regexp implementation along with its version number, and xzless passes the entire version number with attached parenthetical phrase as a number to "test $a -gt $b", producing the above confusing message. $ less-444 -V | head -1 less 444 $ less -V | head -1 less 456 (no regular expressions) So relax the pattern matched --- instead of expecting "less <number>", look for a line of the form "less <number>[ (extra parenthetical)]". While at it, improve the behavior when no matching line is found --- instead of producing a cryptic message, we can fall back on a LESSPIPE setting that is supported by all versions of ‘less’. The implementation uses "awk" for simplicity. Hopefully that’s portable enough. Reported-by: Jörg-Volker Peetz <jvpeetz@web.de> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>

2012-05-28liblzma: Fix possibility of incorrect LZMA_BUF_ERROR.Lasse Collin3-2/+116
lzma_code() could incorrectly return LZMA_BUF_ERROR if all of the following was true: - The caller knows how many bytes of output to expect and only provides that much output space. - When the last output bytes are decoded, the caller-provided input buffer ends right before the LZMA2 end of payload marker. So LZMA2 won't provide more output anymore, but it won't know it yet and thus won't return LZMA_STREAM_END yet. - A BCJ filter is in use and it hasn't left any unfiltered bytes in the temp buffer. This can happen with any BCJ filter, but in practice it's more likely with filters other than the x86 BCJ. Another situation where the bug can be triggered happens if the uncompressed size is zero bytes and no output space is provided. In this case the decompression can fail even if the whole input file is given to lzma_code(). A similar bug was fixed in XZ Embedded on 2011-09-19.
