2015-11-03Build: Fix configure to handle LZMA1 dependency with LZMA2.Lasse Collin1-5/+0
Now it gives an error if LZMA1 encoder/decoder is missing when LZMA2 encoder/decoder was requested. Even better would be LZMA2 implicitly enabling LZMA1 but it would need more code.
2015-11-03Build: Don't omit lzma_cputhreads() unless using --disable-threads.Lasse Collin1-1/+4
Previously it was omitted if encoders were disabled with --disable-encoders. It didn't make sense and it also broke the build.
2015-11-02liblzma: Fix a build failure related to external SHA-256 support.Lasse Collin1-9/+23
If an appropriate header and structure were found by configure, but a library with a usable SHA-256 functions wasn't, the build failed.
2015-11-02xz: Always close the file before trying to delete it.Lasse Collin1-13/+12
unlink() can return EBUSY in errno for open files on some operating systems and file systems.

2015-10-12liblzma: Fix a memory leak in error path of lzma_index_dup().Lasse Collin1-9/+9
lzma_index_dup() calls index_dup_stream() which, in case of an error, calls index_stream_end() to free memory allocated by index_stream_init(). However, it illogically didn't actually free the memory. To make it logical, the tree handling code was modified a bit in addition to changing index_stream_end(). Thanks to Evan Nemerson for the bug report.

2015-08-27Update German translation, mostly wrt orthographyHauke Henningsen1-187/+196
Provide an update of the German translation. * A lot of compound words were previously written with spaces, while German orthography is relatively clear in that the components should not be separated. * When referring to the actual process of (de)compression rather than the concept, replace “(De-)Kompression” with “(De-)Komprimierung”. Previously, both forms were used in this context and are now used in a manner consistent with “Komprimierung” being more likely to refer to a process. * Consistently translate “standard input”/“output” * Use “Zeichen” instead of false friend “Charakter” for “character” * Insert commas around relative clauses (as required in German) * Some other minor corrections * Capitalize “ß” as “ẞ” * Consistently start option descriptions in --help with capital letters Acked-By: Andre Noll <maan@tuebingen.mpg.de> * Update after msgmerge
2015-08-11Build: Minor Cygwin cleanup.Lasse Collin1-3/+3
Some tests used "cygwin*" and some used "cygwin". I changed them all to use "cygwin". Shouldn't affect anything in practice.

2015-06-10Fix typo in German translation.Andre Noll1-1/+1
As pointed out by Robert Pollak, there's a typo in the German translation of the compression preset option (-0 ... -9) help text. "The compressor" translates to "der Komprimierer", and the genitive form is "des Komprimierers". The old word makes no sense at all.

2015-04-20Revert "xz: Use pipe2() if available."Lasse Collin2-10/+3
This reverts commit 7a11c4a8e5e15f13d5fa59233b3172e65428efdd. It is a problem when libc has pipe2() but the kernel is too old to have pipe2() and thus pipe2() fails. In xz it's pointless to have a fallback for non-functioning pipe2(); it's better to avoid pipe2() completely. Thanks to Michael Fox for the bug report.
2015-04-01xz: Fix the Capsicum rights on user_abort_pipe.Lasse Collin1-1/+5
2015-03-31Update THANKS.Lasse Collin1-0/+1
2015-03-31xz: Add support for sandboxing with Capsicum.Lasse Collin6-1/+151
The sandboxing is used conditionally as described in main.c. This isn't optimal but it was much easier to implement than a full sandboxing solution and it still covers the most common use cases where xz is writing to standard output. This should have practically no effect on performance even with small files as fork() isn't needed. C and locale libraries can open files as needed. This has been fine in the past, but it's a problem with things like Capsicum. io_sandbox_enter() tries to ensure that various locale-related files have been loaded before cap_enter() is called, but it's possible that there are other similar problems which haven't been seen yet. Currently Capsicum is available on FreeBSD 10 and later and there is a port to Linux too. Thanks to Loganaden Velvindron for help.
2015-03-31Fix bugs and otherwise improve ax_check_capsicum.m4.Lasse Collin1-52/+51
AU_ALIAS was removed because the new version is incompatible with the old version. It no longer checks for <sys/capability.h> separately. It's enough to test for it as part of AC_CHECK_DECL. The defines HAVE_CAPSICUM_SYS_CAPSICUM_H and HAVE_CAPSICUM_SYS_CAPABILITY_H were removed as unneeded. HAVE_SYS_CAPSICUM_H from AC_CHECK_HEADERS is enough. It no longer does a useless search for the Capsicum library if the header wasn't found. Fixed a bug in ACTION-IF-FOUND (the first argument). Specifying the argument omitted the default action but the given action wasn't used instead. AC_DEFINE([HAVE_CAPSICUM]) is now always called when Capsicum support is found. Previously it was part of the default ACTION-IF-FOUND which a custom action would override. Now the default action only prepends ${CAPSICUM_LIB} to LIBS. The documentation was updated. Since there as no serial number, "#serial 2" was added.
2015-03-31Add m4/ax_check_capsicum.m4 for detecting Capsicum support.Lasse Collin1-0/+86
The file was loaded from this web page: https://github.com/google/capsicum-test/blob/dev/autoconf/m4/ax_check_capsicum.m4 Thanks to Loganaden Velvindron for pointing it out for me.
2015-03-30Bump version to 5.3.0alpha and soname to 5.3.99.Lasse Collin2-4/+4
The idea of 99 is that it looks a bit weird in this context. For new features there's no API/ABI stability in devel versions.

2015-03-29Fix the detection of installed RAM on QNX.Lasse Collin2-4/+16
The earlier version compiled but didn't actually work since sysconf(_SC_PHYS_PAGES) always fails (or so I was told). Thanks to Ole André Vadla Ravnås for the patch and testing.
2015-03-27Fix CPU core count detection on QNX.Lasse Collin1-4/+11
It tried to use sysctl() on QNX but - it broke the build because sysctl() needs -lsocket on QNX; - sysctl() doesn't work for detecting the core count on QNX even if it compiled. sysconf() works. An alternative would have been to use QNX-specific SYSPAGE_ENTRY(num_cpu) from <sys/syspage.h>. Thanks to Ole André Vadla Ravnås.

2015-02-21liblzma: Fix a compression-ratio regression in LZMA1/2 in fast mode.Lasse Collin1-1/+1
The bug was added in the commit f48fce093b07aeda95c18850f5e086d9f2383380 and thus affected 5.1.4beta and 5.2.0. Luckily the bug cannot cause data corruption or other nasty things.
2015-02-21xz: Fix the fcntl() usage when creating a pipe for the self-pipe trick.Lasse Collin1-5/+11
Now it reads the old flags instead of blindly setting O_NONBLOCK. The old code may have worked correctly, but this is better.

2015-01-07xz: Don't fail if stdin doesn't support O_NONBLOCK.Lasse Collin1-11/+7
It's a problem at least on OpenBSD which doesn't support O_NONBLOCK on e.g. /dev/null. I'm not surprised if it's a problem on other OSes too since this behavior is allowed in POSIX-1.2008. The code relying on this behavior was committed in June 2013 and included in 5.1.3alpha released on 2013-10-26. Clearly the development releases only get limited testing.
2015-01-06Tests: Don't hide unexpected error messages in test_files.sh.Lasse Collin1-2/+2
Hiding them makes no sense since normally there's no error when testing the "good" files. With "bad" files errors are expected and then it makes sense to keep the messages hidden.
2014-12-30Update Solaris notes in INSTALL.Lasse Collin1-0/+4

I know that soname != app version, but I skip AGE=1 in -version-info to make the soname match the liblzma version anyway. It doesn't hurt anything as long as it doesn't conflict with library versioning rules.

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.

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.

2014-11-10xzdiff: 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

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.

2014-08-03liblzma: 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

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.

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.

2014-05-25liblzma: 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.

2014-05-04liblzma: 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.

2014-01-12Windows: 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.

Unsurprisingly it makes no difference in compiled output.

Since the only call to suffix_set() uses optarg as the argument, fixing this bug doesn't change the behavior of the program.

2013-11-12xz: 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.

2013-10-22xz: 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.

2013-09-17Add 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.

2013-07-04xz: 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.

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().

2013-06-30Man 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.
