XZ Utils Release Notes
======================
5.6.1 (2024-03-09)
* liblzma: Fixed two bugs relating to GNU indirect function (IFUNC)
with GCC. The more serious bug caused a program linked with
liblzma to crash on start up if the flag -fprofile-generate was
used to build liblzma. The second bug caused liblzma to falsely
report an invalid write to Valgrind when loading liblzma.
* xz: Changed the messages for thread reduction due to memory
constraints to only appear under the highest verbosity level.
* Build:
- Fixed a build issue when the header file <linux/landlock.h>
was present on the system but the Landlock system calls were
not defined in <sys/syscall.h>.
- The CMake build now warns and disables NLS if both gettext
tools and pre-created .gmo files are missing. Previously,
this caused the CMake build to fail.
* Minor improvements to man pages.
* Minor improvements to tests.
5.6.0 (2024-02-24)
This bumps the minor version of liblzma because new features were
added. The API and ABI are still backward compatible with liblzma
5.4.x and 5.2.x and 5.0.x.
NOTE: As described in the NEWS for 5.5.2beta, the core components
are now under the BSD Zero Clause License (0BSD).
Since 5.5.2beta:
* liblzma:
- Disabled the branchless C variant in the LZMA decoder based
on the benchmark results from the community.
- Disabled x86-64 inline assembly on x32 to fix the build.
* Sandboxing support in xz:
- Landlock is now used even when xz needs to create files.
In this case the sandbox has to be more permissive than
when no files need to be created. A similar thing was
already in use with pledge(2) since 5.3.4alpha.
- Landlock and pledge(2) are now stricter when reading from
more than one input file and only writing to standard output.
- Added support for Landlock ABI version 4.
* CMake:
- Default to -O2 instead of -O3 with CMAKE_BUILD_TYPE=Release.
-O3 is not useful for speed and makes the code larger.
- Now builds lzmainfo and lzmadec.
- xzdiff, xzgrep, xzless, xzmore, and their symlinks are now
installed. The scripts are also tested during "make test".
- Added translation support for xz, lzmainfo, and the
man pages.
- Applied the symbol versioning workaround for MicroBlaze that
is used in the Autotools build.
- The general XZ Utils and liblzma API documentation is now
installed.
- The CMake component names were changed a little and several
were added. liblzma_Runtime and liblzma_Development are
unchanged.
- Minimum required CMake version is now 3.14. However,
translation support is disabled with CMake versions
older than 3.20.
- The CMake-based build is now close to feature parity with the
Autotools-based build. Most importantly a few tests aren't
run yet. Testing the CMake-based build on different operating
systems would be welcome now. See the comment at the top of
CMakeLists.txt.
* Fixed a bug in the Autotools feature test for ARM64 CRC32
instruction support for old versions of Clang. This did not
affect the CMake build.
* Windows:
- The build instructions in INSTALL and windows/INSTALL*.txt
were revised completely.
- windows/build-with-cmake.bat along with the instructions
in windows/INSTALL-MinGW-w64_with_CMake.txt should make
it very easy to build liblzma.dll and xz.exe on Windows
using CMake and MinGW-w64 with either GCC or Clang/LLVM.
- windows/build.bash was updated. It now works on MSYS2 and
on GNU/Linux (cross-compiling) to create a .zip and .7z
package for 32-bit and 64-bit x86 using GCC + MinGW-w64.
* The TODO file is no longer installed as part of the
documentation. The file is out of date and does not reflect
the actual tasks that will be completed in the future.
* Translations:
- Translated lzmainfo man pages are now installed. These
had been forgotten in earlier versions.
- Updated Croatian, Esperanto, German, Hungarian, Korean,
Polish, Romanian, Spanish, Swedish, Vietnamese, and Ukrainian
translations.
- Updated German, Korean, Romanian, and Ukrainian man page
translations.
* Added a few tests.
Summary of new features added in the 5.5.x development releases:
* liblzma:
- LZMA decoder: Speed optimizations to the C code and
added GCC & Clang compatible inline assembly for x86-64.
- Added lzma_mt_block_size() to recommend a Block size for
multithreaded encoding.
- Added CLMUL-based CRC32 on x86-64 and E2K with runtime
processor detection. Similar to CRC64, on 32-bit x86 it
isn't available unless --disable-assembler is used.
- Optimized the CRC32 calculation on ARM64 platforms using the
CRC32 instructions. Runtime detection for the instruction is
used on GNU/Linux, FreeBSD, Windows, and macOS. If the
compiler flags indicate unconditional CRC32 instruction
support (+crc) then the generic version is not built.
- Added definitions of mask values like
LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.
* xz:
- Multithreaded mode is now the default. This improves
compression speed and creates .xz files that can be
decompressed in multithreaded mode. The downsides are
increased memory usage and slightly worse compression ratio.
- Added a new command line option --filters to set the filter
chain using the liblzma filter string syntax.
- Added new command line options --filters1 ... --filters9 to
set additional filter chains using the liblzma filter string
syntax. The --block-list option now allows specifying filter
chains that were set using these new options.
- Ported the command line tools to Windows MSVC.
Visual Studio 2015 or later is required.
* Added lz4 support to xzdiff/xzcmp and xzgrep.
5.5.2beta (2024-02-14)
* Licensing change: The core components are now under the
BSD Zero Clause License (0BSD). In XZ Utils 5.4.6 and older
and 5.5.1alpha these components are in the public domain and
obviously remain so; the change affects the new releases only.
0BSD is an extremely permissive license which doesn't require
retaining or reproducing copyright or license notices when
distributing the code, thus in practice there is extremely
little difference to public domain.
* liblzma
- Significant speed optimizations to the LZMA decoder were
made. There are now three variants that can be chosen at
build time:
* Basic C version: This is a few percent faster than
5.4.x due to some new optimizations.
* Branchless C: This is currently the default on platforms
for which there is no assembly code. This should be a few
percent faster than the basic C version.
* x86-64 inline assembly. This works with GCC and Clang.
The default choice can currently be overridden by setting
LZMA_RANGE_DECODER_CONFIG in CPPFLAGS: 0 means the basic
version and 3 means that branchless C version.
- Optimized the CRC32 calculation on ARM64 platforms using the
CRC32 instructions. The instructions are optional in ARMv8.0
and are required in ARMv8.1 and later. Runtime detection for
the instruction is used on GNU/Linux, FreeBSD, Windows, and
macOS. If the compiler flags indicate unconditional CRC32
instruction support (+crc) then the generic version is not
built.
* Added lz4 support to xzdiff/xzcmp and xzgrep.
* Man pages of xzdiff/xzcmp, xzgrep, and xzmore were rewritten
to simplify licensing of the man page translations.
* Translations:
- Updated Chinese (simplified), German, Korean, Polish,
Romanian, Spanish, Swedish, and Ukrainian translations.
- Updated German, Korean, Romanian, and Ukrainian man page
translations.
* Small improvements to the tests.
* Added doc/examples/11_file_info.c. It was added to the Git
repository in 2017 but forgotten to be added into distribution
tarballs.
* Removed doc/examples_old. These were from 2012.
* Removed the macos/build.sh script. It had not been updated
since 2013.
5.5.1alpha (2024-01-26)
* Added a new filter for RISC-V binaries. The filter can be used
for 32-bit and 64-bit binaries with either little or big
endianness. In liblzma, the Filter ID is LZMA_FILTER_RISCV (0x0B)
and the xz option is --riscv. liblzma filter string syntax
recognizes this filter as "riscv".
* liblzma:
- Added lzma_mt_block_size() to recommend a Block size for
multithreaded encoding
- Added CLMUL-based CRC32 on x86-64 and E2K with runtime
processor detection. Similar to CRC64, on 32-bit x86 it
isn't available unless --disable-assembler is used.
- Implemented GNU indirect function (IFUNC) as a runtime
function dispatching method for CRC32 and CRC64 fast
implementations on x86. Only GNU/Linux (glibc) and FreeBSD
builds will use IFUNC, unless --enable-ifunc is specified to
configure.
- Added definitions of mask values like
LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.
- The XZ logo is now included in the Doxygen generated
documentation. It is licensed under Creative Commons
Attribution-ShareAlike 4.0.
* xz:
- Multithreaded mode is now the default. This improves
compression speed and creates .xz files that can be
decompressed multithreaded at the cost of increased memory
usage and slightly worse compression ratio.
- Added new command line option --filters to set the filter
chain using liblzma filter string syntax.
- Added new command line options --filters1 ... --filters9 to
set additional filter chains using liblzma filter string
syntax. The --block-list option now allows specifying filter
chains that were set using these new options.
- Added support for Linux Landlock as a sandboxing method.
- xzdec now supports pledge(2), Capsicum, and Linux Landlock as
sandboxing methods.
- Progress indicator time stats remain accurate after pausing
xz with SIGTSTP.
- Ported xz and xzdec to Windows MSVC. Visual Studio 2015 or
later is required.
* CMake Build:
- Supports pledge(2), Capsicum, and Linux Landlock sandboxing
methods.
- Replacement functions for getopt_long() are used on platforms
that do not have it.
* Enabled unaligned access by default on PowerPC64LE and on RISC-V
targets that define __riscv_misaligned_fast.
* Tests:
- Added two new fuzz targets to OSS-Fuzz.
- Implemented Continuous Integration (CI) testing using
GitHub Actions.
* Changed quoting style from `...' to '...' in all messages,
scripts, and documentation.
* Added basic Codespell support to help catch typo errors.
5.4.6 (2024-01-26)
* Fixed a bug involving internal function pointers in liblzma not
being initialized to NULL. The bug can only be triggered if
lzma_filters_update() is called on a LZMA1 encoder, so it does
not affect xz or any application known to us that uses liblzma.
* xz:
- Fixed a regression introduced in 5.4.2 that caused encoding
in the raw format to unnecessarily fail if --suffix was not
used. For instance, the following command no longer reports
that --suffix must be used:
echo foo | xz --format=raw --lzma2 | wc -c
- Fixed an issue on MinGW-w64 builds that prevented reading
from or writing to non-terminal character devices like NUL.
* Added a new test.
5.4.5 (2023-11-31)
* liblzma:
- Use __attribute__((__no_sanitize_address__)) to avoid address
sanitization with CRC64 CLMUL. It uses 16-byte-aligned reads
which can extend past the bounds of the input buffer and
inherently trigger address sanitization errors. This isn't
a bug.
- Fixed an assertion failure that could be triggered by a large
unpadded_size argument. It was verified that there was no
other bug than the assertion failure.
- Fixed a bug that prevented building with Windows Vista
threading when __attribute__((__constructor__)) is not
supported.
* xz now properly handles special files such as "con" or "nul" on
Windows. Before this fix, the following wrote "foo" to the
console and deleted the input file "con_xz":
echo foo | xz > con_xz
xz --suffix=_xz --decompress con_xz
* Build systems:
- Allow builds with Windows win95 threading and small mode when
__attribute__((__constructor__)) is supported.
- Added a new line to liblzma.pc for MSYS2 (Windows):
Cflags.private: -DLZMA_API_STATIC
When compiling code that will link against static liblzma,
the LZMA_API_STATIC macro needs to be defined on Windows.
- CMake specific changes:
* Fixed a bug that allowed CLOCK_MONOTONIC to be used even
if the check for it failed.
* Fixed a bug where configuring CMake multiple times
resulted in HAVE_CLOCK_GETTIME and HAVE_CLOCK_MONOTONIC
not being set.
* Fixed the build with MinGW-w64-based Clang/LLVM 17.
llvm-windres now has more accurate GNU windres emulation
so the GNU windres workaround from 5.4.1 is needed with
llvm-windres version 17 too.
* The import library on Windows is now properly named
"liblzma.dll.a" instead of "libliblzma.dll.a"
* Fixed a bug causing the Ninja Generator to fail on
UNIX-like systems. This bug was introduced in 5.4.0.
* Added a new option to disable CLMUL CRC64.
* A module-definition (.def) file is now created when
building liblzma.dll with MinGW-w64.
* The pkg-config liblzma.pc file is now installed on all
builds except when using MSVC on Windows.
* Added large file support by default for platforms that
need it to handle files larger than 2 GiB. This includes
MinGW-w64, even 64-bit builds.
* Small fixes and improvements to the tests.
* Updated translations: Chinese (simplified) and Esperanto.
5.4.4 (2023-08-02)
* liblzma and xzdec can now build against WASI SDK when threading
support is disabled. xz and tests don't build yet.
* CMake:
- Fixed a bug preventing other projects from including liblzma
multiple times using find_package().
- Don't create broken symlinks in Cygwin and MSYS2 unless
supported by the environment. This prevented building for the
default MSYS2 environment. The problem was introduced in
xz 5.4.0.
* Documentation:
- Small improvements to man pages.
- Small improvements and typo fixes for liblzma API
documentation.
* Tests:
- Added a new section to INSTALL to describe basic test usage
and address recent questions about building the tests when
cross compiling.
- Small fixes and improvements to the tests.
* Translations:
- Fixed a mistake that caused one of the error messages to not
be translated. This only affected versions 5.4.2 and 5.4.3.
- Updated the Chinese (simplified), Croatian, Esperanto, German,
Korean, Polish, Romanian, Spanish, Swedish, Ukrainian, and
Vietnamese translations.
- Updated the German, Korean, Romanian, and Ukrainian man page
translations.
5.4.3 (2023-05-04)
* All fixes from 5.2.12
* Features in the CMake build can now be disabled as CMake cache
variables, similar to the Autotools build.
* Minor update to the Croatian translation.
5.4.2 (2023-03-18)
* All fixes from 5.2.11 that were not included in 5.4.1.
* If xz is built with support for the Capsicum sandbox but running
in an environment that doesn't support Capsicum, xz now runs
normally without sandboxing instead of exiting with an error.
* liblzma:
- Documentation was updated to improve the style, consistency,
and completeness of the liblzma API headers.
- The Doxygen-generated HTML documentation for the liblzma API
header files is now included in the source release and is
installed as part of "make install". All JavaScript is
removed to simplify license compliance and to reduce the
install size.
- Fixed a minor bug in lzma_str_from_filters() that produced
too many filters in the output string instead of reporting
an error if the input array had more than four filters. This
bug did not affect xz.
* Build systems:
- autogen.sh now invokes the doxygen tool via the new wrapper
script doxygen/update-doxygen, unless the command line option
--no-doxygen is used.
- Added microlzma_encoder.c and microlzma_decoder.c to the
VS project files for Windows and to the CMake build. These
should have been included in 5.3.2alpha.
* Tests:
- Added a test to the CMake build that was forgotten in the
previous release.
- Added and refactored a few tests.
* Translations:
- Updated the Brazilian Portuguese translation.
- Added Brazilian Portuguese man page translation.

5.2.12 (2023-05-04)
* Fixed a build system bug that prevented building liblzma as a
shared library when configured with --disable-threads. This bug
affected releases 5.2.6 to 5.2.11 and 5.4.0 to 5.4.2.
* Include <intrin.h> for Windows intrinsic functions where they are
needed. This fixed a bug that prevented building liblzma using
clang-cl on Windows.
* Minor update to the Croatian translation. The small change
applies to a string in both 5.2 and 5.4 branches.
5.2.11 (2023-03-18)
* Removed all possible cases of null pointer + 0. It is undefined
behavior in C99 and C17. This was detected by a sanitizer and had
not caused any known issues.
* Build systems:
- Added a workaround for building with GCC on MicroBlaze Linux.
GCC 12 on MicroBlaze doesn't support the __symver__ attribute
even though __has_attribute(__symver__) returns true. The
build is now done without the extra RHEL/CentOS 7 symbols
that were added in XZ Utils 5.2.7. The workaround only
applies to the Autotools build (not CMake).
- CMake: Ensure that the C compiler language is set to C99 or
a newer standard.
- CMake changes from XZ Utils 5.4.1:
* Added a workaround for a build failure with
windres from GNU binutils.
* Included the Windows resource files in the xz
and xzdec build rules.

----------
If the package manager supports a license field, you probably should
put GPLv2+ there (GNU GPL v2 or later). The interesting parts of
XZ Utils are in the public domain, but some less important files
ending up into the binary package are under GPLv2+. So it is simplest
to just say GPLv2+ if you cannot specify "public domain and GPLv2+".
XZ Utils are under the BSD Zero Clause License (0BSD), but some less
important files ending up into the binary package are under GPLv2+.
So it is simplest to just say GPLv2+ if you cannot specify
"BSD0 and GPLv2+".
If you split XZ Utils into multiple packages as described earlier
in this file, liblzma and liblzma-dev packages will contain only
public domain code (from XZ Utils at least; compiler or linker may
add some third-party code, which may be copyrighted).

liblzma API is currently only documented using Doxygen tags in the
API headers. It hasn't been tested much how good results Doxygen
is able to make from the tags (e.g. Doxyfile might need tweaking,
the tagging may need to be improved etc.), so it might be simpler
to just let people read docs directly from the .h files for now,
and also save quite a bit in package size at the same time.
The Doxygen-generated documentation (HTML) for the liblzma API
headers is included in the source release and will be installed by
"make install" to $docdir/api. All JavaScript is removed to
simplify license compliance and to reduce the install size. If the
liblzma API documentation is not desired, either run configure with
--disable-doc or remove the doc/api directory before running
"make install".

// build time. A third method, casting to a packed struct, would also be
// an option but isn't provided to keep things simpler (it's already a mess).
// Hopefully this is flexible enough in practice.
//
// Some compilers on x86-64 like Clang >= 10 and GCC >= 5.1 detect that
//
// buf[0] | (buf[1] << 8)
//
// reads a 16-bit value and can emit a single 16-bit load and produce
// identical code than with the memcpy() method. In other cases Clang and GCC
// produce either the same or better code with memcpy(). For example, Clang 9
// on x86-64 can detect 32-bit load but not 16-bit load.
//
// MSVC uses unaligned access with the memcpy() method but emits byte-by-byte
// code for "buf[0] | (buf[1] << 8)".
//
// Conclusion: The memcpy() method is the best choice when unaligned access
// is supported.
//
// Strict-align archs like SPARC
// -----------------------------
//
// GCC versions from around 4.x to to at least 13.2.0 produce worse code
// from the memcpy() method than from simple byte-by-byte shift-or code
// when reading a 32-bit integer:
//
// (1) It may be constructed on stack using using four 8-bit loads,
// four 8-bit stores to stack, and finally one 32-bit load from stack.
//
// (2) Especially with -Os, an actual memcpy() call may be emitted.
//
// This is true on at least on ARM, ARM64, SPARC, SPARC64, MIPS64EL, and
// RISC-V. Of these, ARM, ARM64, and RISC-V support unaligned access in
// some processors but not all so this is relevant only in the case when
// GCC assumes that unaligned is not supported or -mstrict-align or
// -mno-unaligned-access is used.
//
// For Clang it makes little difference. ARM64 with -O2 -mstrict-align
// was one the very few with a minor difference: the memcpy() version
// was one instruction longer.
//
// Conclusion: At least in case of GCC and Clang, byte-by-byte code is
// the best choice for strict-align archs to do unaligned access.
//

//////////////////////////
// If both the generic and arch-optimized implementations are built, then
// the function to use is selected at runtime because the system running
// the binary might not have the arch-specific instruction set extension(s)
// available. The three dispatch methods in order of priority:
//
// 1. Indirect function (ifunc). This method is slightly more efficient
// than the constructor method because it will change the entry in the
// Procedure Linkage Table (PLT) for the function either at load time or
// at the first call. This avoids having to call the function through a
// function pointer and will treat the function call like a regular call
// through the PLT. ifuncs are created by using
// __attribute__((__ifunc__("resolver"))) on a function which has no
// body. The "resolver" is the name of the function that chooses at
// runtime which implementation to use.
//
// 2. Constructor. This method uses __attribute__((__constructor__)) to
// set crc32_func at load time. This avoids extra computation (and any
// unlikely threading bugs) on the first call to lzma_crc32() to decide
// which implementation should be used.
//
// 3. First Call Resolution. On the very first call to lzma_crc32(), the
// call will be directed to crc32_dispatch() instead. This will set the
// appropriate implementation function and will not be called again.
// This method does not use any kind of locking but is safe because if
// multiple threads run the dispatcher simultaneously then they will all
// set crc32_func to the same value.
