XZ Utils Release Notes XZ Utils Release Notes
====================== ======================
5.3.2alpha (2021-10-28)
This release was made on short notice so that recent erofs-utils can
be built with LZMA support without needing a snapshot from xz.git.
Thus many pending things were not included, not even updated
translations (which would need to be updated for the new --list
strings anyway).
* All fixes from 5.2.5.
* xz:
- When copying metadata from the source file to the destination
file, don't try to set the group (GID) if it is already set
correctly. This avoids a failure on OpenBSD (and possibly on
a few other OSes) where files may get created so that their
group doesn't belong to the user, and fchown(2) can fail even
if it needs to do nothing.
- The --keep option now accepts symlinks, hardlinks, and
setuid, setgid, and sticky files. Previously this required
using --force.
- Split the long strings used in --list and --info-memory modes
to make them much easier for translators.
- If built with sandbox support and enabling the sandbox fails,
xz will now immediately exit with exit status of 1. Previously
it would only display a warning if -vv was used.
- Cap --memlimit-compress to 2000 MiB on MIPS32 because on
MIPS32 userspace processes are limited to 2 GiB of address
space.
* liblzma:
- Added lzma_microlzma_encoder() and lzma_microlzma_decoder().
The API is in lzma/container.h.
The MicroLZMA format is a raw LZMA stream (without end marker)
whose first byte (always 0x00) has been replaced with
bitwise-negation of the LZMA properties (lc/lp/pb). It was
created for use in EROFS but may be used in other contexts
as well where it is important to avoid wasting bytes for
stream headers or footers. The format is also supported by
XZ Embedded.
The MicroLZMA encoder API in liblzma can compress into a
fixed-sized output buffer so that as much data is compressed
as can be fit into the buffer while still creating a valid
MicroLZMA stream. This is needed for EROFS.
- Added fuzzing support.
- Support Intel Control-flow Enforcement Technology (CET) in
32-bit x86 assembly files.
- Visual Studio: Use non-standard _MSVC_LANG to detect C++
standard version in the lzma.h API header. It's used to
detect when "noexcept" can be used.
* Scripts:
- Fix exit status of xzdiff/xzcmp. Exit status could be 2 when
the correct value is 1.
- Fix exit status of xzgrep.
- Detect corrupt .bz2 files in xzgrep.
- Add zstd support to xzgrep and xzdiff/xzcmp.
- Fix less(1) version detection in xzless. It failed if the
version number from "less -V" contained a dot.
* Fix typos and technical issues in man pages.
* Build systems:
- Windows: Fix building of resource files when config.h isn't
used. CMake + Visual Studio can now build liblzma.dll.
- Various fixes to the CMake support. It might still need a few
more fixes even for liblzma-only builds.
