Bump version and soname for 5.2.1.
Date: 2015-02-26 13:01:09 +0200
Update NEWS for 5.2.1.
Date: 2015-02-22 19:38:48 +0200
xz: Use pipe2() if available.
Date: 2015-02-21 23:40:26 +0200
liblzma: Fix a compression-ratio regression in LZMA1/2 in fast mode.
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.
Date: 2015-02-21 23:00:19 +0200
xz: Fix the fcntl() usage when creating a pipe for the self-pipe trick.
Now it reads the old flags instead of blindly setting O_NONBLOCK.
The old code may have worked correctly, but this is better.
Date: 2015-02-10 15:29:34 +0200
Update THANKS.
Date: 2015-02-10 15:28:30 +0200
tuklib_cpucores: Use cpuset_getaffinity() on FreeBSD if available.
In FreeBSD, cpuset_getaffinity() is the preferred way to get
the number of available cores.
Thanks to Rui Paulo for the patch. I edited it slightly, but
hopefully I didn't break anything.
Date: 2015-02-09 22:08:37 +0200
xzdiff: Make the mktemp usage compatible with FreeBSD's mktemp.
Thanks to Rui Paulo for the fix.
Date: 2015-02-03 21:45:53 +0200
Add a few casts to tuklib_integer.h to silence possible warnings.
I heard that Visual Studio 2013 gave warnings without the casts.
Thanks to Gabi Davar.
Date: 2015-01-26 21:24:39 +0200
liblzma: Set LZMA_MEMCMPLEN_EXTRA depending on the compare method.
Date: 2015-01-26 20:40:16 +0200
Update THANKS.
Date: 2015-01-26 20:39:28 +0200
liblzma: Silence harmless Valgrind errors.
Thanks to Torsten Rupp for reporting this. I had
forgotten to run Valgrind before the 5.2.0 release.
Date: 2015-01-09 21:50:19 +0200
xz: Fix comments.
Date: 2015-01-09 21:35:06 +0200
Update THANKS.
Date: 2015-01-09 21:34:06 +0200
xz: Don't fail if stdout doesn't support O_NONBLOCK.
This is similar to the case with stdin.
Thanks to Brad Smith for the bug report and testing
on OpenBSD.
Date: 2015-01-07 19:18:20 +0200
xz: Fix a memory leak in DOS-specific code.
Date: 2015-01-07 19:08:06 +0200
xz: Don't fail if stdin doesn't support O_NONBLOCK.
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.
Date: 2015-01-06 20:30:15 +0200
Tests: Don't hide unexpected error messages in test_files.sh.
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.
Date: 2014-12-30 11:17:16 +0200
Update Solaris notes in INSTALL.
Mention the possible "make check" failure on Solaris in the
Solaris-specific section of INSTALL. It was already in
section 4.5 but it is better mention it in the OS-specific
section too.
Date: 2014-12-26 12:00:05 +0200
Build: POSIX shell isn't required if scripts are disabled.
Date: 2014-12-21 20:48:37 +0200
DOS: Update Makefile.
Date: 2014-12-21 19:50:38 +0200
Windows: Fix bin_i486 to bin_i686 in build.bash.
Date: 2014-12-21 18:58:44 +0200
Docs: Use lzma_cputhreads() in 04_compress_easy_mt.c.
Date: 2014-12-21 18:56:44 +0200
Docs: Update docs/examples/00_README.txt.
Date: 2014-12-21 18:11:17 +0200
Bump version and soname for 5.2.0.
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.
Date: 2014-12-21 18:05:03 +0200
Avoid variable-length arrays in the debug programs.
Date: 2014-12-21 18:01:45 +0200
Build: Include 04_compress_easy_mt.c in the tarball.
Date: 2014-12-21 18:00:38 +0200
Fix build when --disable-threads is used.
Date: 2014-12-21 15:56:15 +0100
po/fr: improve wording for help for --lzma1/--lzma2.
Date: 2014-12-21 15:55:48 +0100

Update INSTALL about the dependencies of the scripts.
Date: 2014-12-20 20:42:33 +0200
Windows: Update build instructions.
Date: 2014-12-20 20:41:48 +0200
Windows: Update the build script and README-Windows.txt.
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.
Date: 2014-12-19 15:51:50 +0200
Windows: Define TUKLIB_SYMBOL_PREFIX in config.h.
It is to keep all symbols in the lzma_ namespace.
Date: 2014-12-16 21:00:09 +0200
xz: Update the man page about --threads.
Date: 2014-12-16 20:57:43 +0200
xz: Update the man page about --block-size.
Date: 2014-12-10 22:26:57 +0100
po/fr: several more translation updates: reword and handle --ignore-check.

po/fr: last batch of new translations for now.
Four new error messages.
Date: 2014-12-03 20:01:32 +0100
po/fr: translations for --threads, --block-size and --block-list.
Date: 2014-12-03 20:00:53 +0100
po/fr: remove fuzzy marker for error messages that will be kept in English.
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.
Date: 2014-12-03 19:58:25 +0100
po/fr: several minor updates and better wording.
Meaning doesn't change at all: it's only for better wording and/or
formatting of a few strings.
Date: 2014-12-03 19:56:12 +0100
po/fr: update my email address and copyright years.
Date: 2014-11-26 10:08:26 +0100
fr.po: commit file after only "update-po" so actual is readable.
Date: 2014-12-02 20:04:07 +0200
liblzma: Document how lzma_mt.block_size affects memory usage.
Date: 2014-11-28 20:07:18 +0200
Update INSTALL about a "make check" failure in test_scripts.sh.
Date: 2014-11-26 20:12:27 +0200
Remove LZMA_UNSTABLE macro.
Date: 2014-11-26 20:10:33 +0200
liblzma: Update lzma_stream_encoder_mt() API docs.
Date: 2014-11-25 12:32:05 +0200
liblzma: Verify the filter chain in threaded encoder initialization.
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).
Date: 2014-11-17 19:11:49 +0200
Build: Update m4/ax_pthread.m4 from Autoconf Archive.
Date: 2014-11-17 18:52:21 +0200
Build: Replace obsolete AC_HELP_STRING with AS_HELP_STRING.
Date: 2014-11-17 18:43:19 +0200
Build: Fix Autoconf warnings about escaped backquotes.
Thanks to Daniel Richard G. for pointing out that it's
good to sometimes run autoreconf -fi with -Wall.
Date: 2014-11-10 18:54:40 +0200
xzdiff: Use mkdir if mktemp isn't available.
Date: 2014-11-10 18:45:01 +0200
xzdiff: Create a temporary directory to hold a temporary file.
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.
Date: 2014-11-10 15:38:47 +0200
liblzma: Fix lzma_mt.preset in lzma_stream_encoder_mt_memusage().
It read the filter chain from a wrong variable. This is a similar
bug that was fixed in 9494fb6d0ff41c585326f00aa8f7fe58f8106a5e.
Date: 2014-11-10 14:49:55 +0200

Build: Prepare to support Automake's subdir-objects.
Due to a bug in Automake, subdir-objects won't be enabled
for now.

xzgrep: Avoid passing both -q and -l to grep.
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.

liblzma: Fix a portability problem in Makefile.am.
POSIX supports $< only in inference rules (suffix rules).
Using it elsewhere is a GNU make extension and doesn't

liblzma: Add support for LZMA_IGNORE_CHECK.
Date: 2014-08-05 22:03:30 +0300
liblzma: Add support for lzma_block.ignore_check.
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.

liblzma: Use lzma_memcmplen() in the BT3 match finder.

liblzma: SHA-256: Optimize the Maj macro slightly.
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>.
Date: 2014-08-03 21:08:12 +0300
liblzma: SHA-256: Optimize the way rotations are done.
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.
Date: 2014-08-03 20:38:13 +0300
liblzma: SHA-256: Remove the GCC #pragma that became unneeded.
The unrolling in the previous commit should avoid the
situation where a compiler may think that an uninitialized
variable might be accessed.
Date: 2014-08-03 20:33:38 +0300
liblzma: SHA-256: Unroll a little more.
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.
Date: 2014-08-03 19:56:43 +0300

liblzma: Add lzma_memcmplen() for fast memory comparison.
This commit just adds the function. Its uses will be in

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.

liblzma: Use lzma_alloc_zero() in LZ encoder initialization.
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.

Build: Fix the combination of --disable-xzdec --enable-lzmadec.
In this case "make install" could fail if the man page directory

instead. This isn't the best fix but it's better than the old
behavior.

xz: Rename a variable to avoid a namespace collision on Solaris.
I don't know the details but I have an impression that there's

Windows: Add config.h for building liblzma with MSVC 2013.
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:

for readability either since many aren't used to them.
Date: 2014-01-12 12:50:30 +0200
liblzma: Remove a useless C99ism from sha256.c.
Unsurprisingly it makes no difference in compiled output.
Date: 2014-01-12 12:17:08 +0200
xz: Fix use of wrong variable.
Since the only call to suffix_set() uses optarg
as the argument, fixing this bug doesn't change
the behavior of the program.
Date: 2014-01-12 12:11:36 +0200
Fix typos in comments.

liblzma: Document the need for block->check for lzma_block_header_decode().
Thanks to Tomer Chachamu.

xz: Make --block-list and --block-size work together in single-threaded.
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.

Bump the version number to 5.1.3alpha.
Date: 2013-10-26 13:25:02 +0300
Update NEWS for 5.1.3alpha.

Update TODO.
Date: 2013-10-25 22:41:28 +0300
xz: Document behavior of --block-list with threads.
This needs to be updated before 5.2.0.
Date: 2013-10-22 20:03:12 +0300
xz: Document --flush-timeout=TIMEOUT on the man page.
Date: 2013-10-22 19:51:55 +0300
xz: Take advantage of LZMA_FULL_BARRIER with --block-list.
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.
Date: 2013-10-02 20:05:23 +0300
liblzma: Support LZMA_FULL_FLUSH and _BARRIER in threaded encoder.
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.
Date: 2013-10-02 12:55:11 +0300
liblzma: Add LZMA_FULL_BARRIER support to single-threaded encoder.
In the single-threaded encoder LZMA_FULL_BARRIER is simply
an alias for LZMA_FULL_FLUSH.
Date: 2013-09-17 11:57:51 +0300
liblzma: Add block_buffer_encoder.h into Makefile.inc.
This should have been in b465da5988dd59ad98fda10c2e4ea13d0b9c73bc.
Date: 2013-09-17 11:55:38 +0300
xz: Add a missing test for TUKLIB_DOSLIKE.
Date: 2013-09-17 11:52:28 +0300
Add native threading support on Windows.
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.

Build: Remove a comment about Automake 1.10 from configure.ac.
The previous commit supports silent rules and that requires
Automake 1.11.
Date: 2013-09-09 20:37:03 +0300
Build: Create liblzma.pc in a src/liblzma/Makefile.am.
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.

Fix the previous commit which broke the build.
Apparently I didn't even compile-test the previous commit.
Thanks to Christian Hesse.
Date: 2013-08-03 13:52:58 +0300
Windows: Add Windows support to tuklib_cpucores().
It is used for Cygwin too. I'm not sure if that is
a good or bad idea.
Thanks to Vincent Torri.

xz: Add preliminary support for --flush-timeout=TIMEOUT.
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.
Date: 2013-07-04 13:41:03 +0300
xz: Don't set src_eof=true after an I/O error because it's useless.
Date: 2013-07-04 13:25:11 +0300
xz: Fix the test when to read more input.
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.
Date: 2013-07-04 12:51:57 +0300
xz: Move some of the timing code into mytime.[hc].
This switches units from microseconds to milliseconds.
New clock_gettime(CLOCK_MONOTONIC) will be used if available.
There is still a fallback to gettimeofday().

Update THANKS.
Date: 2013-07-01 14:34:11 +0300
xz: Silence a warning seen with _FORTIFY_SOURCE=2.
Thanks to Christian Hesse.
- memory leak in liblzma fixed
- better validation
- correct behavior for suid/sgid/sticky bit and hard links with xz --force
- cleanup and new translations
Push -Wno-array-bounds down to the cases that depend on it.
Selectively disable warnings for 3rd party software or non-trivial
issues to be reviewed later to get clang -Werror to build most of the
tree.
