+
+ 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.

+
+ 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.

+
+ 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.

+
+ 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.

+ 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.
+
+ Thanks to Christian Weisgerber.

+ 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

+ field is kept unchanged if possible. In practice this doesn't
+ affect any old code, because before this commit the only

+ liblzma: SHA-256: Optimize the Maj macro slightly.
+
+ The Maj macro is used where multiple things are added

+
+ 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.

+Author: Lasse Collin <lasse.collin@tukaani.org>

+
+ 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.

+
+ 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:
+
+ 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.

+ 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.

+
+ 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.

+
+ 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.

+
+ xz: Use the self-pipe trick to avoid a race condition with signals.
+
+ 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.

+
+ Make the progress indicator smooth in threaded mode.
+
+ 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.

+ liblzma: Make the use of lzma_allocator const-correct.
+
+ There is a tiny risk of causing breakage: If an application
+ assigns lzma_stream.allocator to a non-const pointer, such
+ code won't compile anymore. I don't know why anyone would do
+ such a thing though, so in practice this shouldn't cause trouble.
+
+ Thanks to Jan Kratochvil for the patch.

+
+ liblzma: Use symbol versioning.
+
+ 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.

+ liblzma: Try to use SHA-256 from the operating system.
+
+ 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.

+
+ 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.

+ Revise mythread.h.
+
+ 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.

+ I need to get feedback from DOS users before saying
+ that this is the final version of 8.3 filename support.

+
+ xz/DOS: Be more careful with the destination file.
+
+ 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.

time and calculated (de)compression speed won't make sense in the

+ If liblzma has created threads and fork() gets called, liblzma

Missing features
----------------
+ Add support for storing metadata in .xz files. A preliminary
+ idea is to create a new Stream type for metadata. When both
+ metadata and data are wanted in the same .xz file, two or more
+ Streams would be concatenated.
+
+ The state stored in lzma_stream should be cloneable, which would
+ be mostly useful when using a preset dictionary in LZMA2, but
+ it may have other uses too. Compare to deflateCopy() in zlib.
+
+ Support LZMA_FINISH in raw decoder to indicate end of LZMA1 and
+ other streams that don't have an end of payload marker.
+
+ Adjust dictionary size when the input file size is known.
+ Maybe do this only if an option is given.
+
xz doesn't support copying extended attributes, access control
lists etc. from source to target file.
- Multithreaded compression
+ Multithreaded compression:
+ - Reduce memory usage of the current method.
+ - Implement threaded match finders.
+ - Implement pigz-style threading in LZMA2.
Multithreaded decompression

It will be a separate library that supports uncompressed, .gz,
.bz2, .lzma, and .xz files.
+ Support changing lzma_options_lzma.mode with lzma_filters_update().
+
+ Support LZMA_FULL_FLUSH for lzma_stream_decoder() to stop at
+ Block and Stream boundaries.
+
lzma_strerror() to convert lzma_ret to human readable form?
This is tricky, because the same error codes are used with
slightly different meanings, and this cannot be fixed anymore.
+ Make it possible to adjust LZMA2 options in the middle of a Block
+ so that the encoding speed vs. compression ratio can be optimized
+ when the compressed data is streamed over network.
+
+ Improved BCJ filters. The current filters are small but they aren't
+ so great when compressing binary packages that contain various file
+ types. Specifically, they make things worse if there are static
+ libraries or Linux kernel modules. The filtering could also be
+ more effective (without getting overly complex), for example,
+ streamable variant BCJ2 from 7-Zip could be implemented.
+
+ Filter that autodetects specific data types in the input stream
+ and applies appropriate filters for the corrects parts of the input.
+ Perhaps combine this with the BCJ filter improvement point above.
+
+ Long-range LZ77 method as a separate filter or as a new LZMA2
+ match finder.
+
Documentation
-------------
- Some tutorial is needed for liblzma. I have planned to write some
- extremely well commented example programs, which would work as
- a tutorial. I suppose the Doxygen tags are quite OK as a quick
- reference once one is familiar with the liblzma API.
+ More tutorial programs are needed for liblzma.
Document the LZMA1 and LZMA2 algorithms.
+
+Miscellaneous
+------------
+
+ Try to get the media type for .xz registered at IANA.
