5.2.8 (2022-11-13)
|
||||
|
||||
* xz:
|
||||
|
||||
- If xz cannot remove an input file when it should, this
|
||||
is now treated as a warning (exit status 2) instead of
|
||||
an error (exit status 1). This matches GNU gzip and it
|
||||
is more logical as at that point the output file has
|
||||
already been successfully closed.
|
||||
|
||||
- Fix handling of .xz files with an unsupported check type.
|
||||
Previously such printed a warning message but then xz
|
||||
behaved as if an error had occurred (didn't decompress,
|
||||
exit status 1). Now a warning is printed, decompression
|
||||
is done anyway, and exit status is 2. This used to work
|
||||
slightly before 5.0.0. In practice this bug matters only
|
||||
if xz has been built with some check types disabled. As
|
||||
instructed in PACKAGERS, such builds should be done in
|
||||
special situations only.
|
||||
|
||||
- Fix "xz -dc --single-stream tests/files/good-0-empty.xz"
|
||||
which failed with "Internal error (bug)". That is,
|
||||
--single-stream was broken if the first .xz stream in
|
||||
the input file didn't contain any uncompressed data.
|
||||
|
||||
- Fix displaying file sizes in the progress indicator when
|
||||
working in passthru mode and there are multiple input files.
|
||||
Just like "gzip -cdf", "xz -cdf" works like "cat" when the
|
||||
input file isn't a supported compressed file format. In
|
||||
this case the file size counters weren't reset between
|
||||
files so with multiple input files the progress indicator
|
||||
displayed an incorrect (too large) value.
|
||||
|
||||
* liblzma:
|
||||
|
||||
- API docs in lzma/container.h:
|
||||
* Update the list of decoder flags in the decoder
|
||||
function docs.
|
||||
* Explain LZMA_CONCATENATED behavior with .lzma files
|
||||
in lzma_auto_decoder() docs.
|
||||
|
||||
- OpenBSD: Use HW_NCPUONLINE to detect the number of
|
||||
available hardware threads in lzma_physmem().
|
||||
|
||||
- Fix use of wrong macro to detect x86 SSE2 support.
|
||||
__SSE2_MATH__ was used with GCC/Clang but the correct
|
||||
one is __SSE2__. The first one means that SSE2 is used
|
||||
for floating point math which is irrelevant here.
|
||||
The affected SSE2 code isn't used on x86-64 so this affects
|
||||
only 32-bit x86 builds that use -msse2 without -mfpmath=sse
|
||||
(there is no runtime detection for SSE2). It improves LZMA
|
||||
compression speed (not decompression).
|
||||
|
||||
- Fix the build with Intel C compiler 2021 (ICC, not ICX)
|
||||
on Linux. It defines __GNUC__ to 10 but doesn't support
|
||||
the __symver__ attribute introduced in GCC 10.
|
||||
|
||||
* Scripts: Ignore warnings from xz by using --quiet --no-warn.
|
||||
This is needed if the input .xz files use an unsupported
|
||||
check type.
|
||||
|
||||
* Translations:
|
||||
|
||||
- Updated Croatian and Turkish translations.
|
||||
|
||||
- One new translations wasn't included because it needed
|
||||
technical fixes. It will be in upcoming 5.4.0. No new
|
||||
translations will be added to the 5.2.x branch anymore.
|
||||
|
||||
- Renamed the French man page translation file from
|
||||
fr_FR.po to fr.po and thus also its install directory
|
||||
(like /usr/share/man/fr_FR -> .../fr).
|
||||
|
||||
- Man page translations for upcoming 5.4.0 are now handled
|
||||
in the Translation Project.
|
||||
|
||||
* Update doc/faq.txt a little so it's less out-of-date.

||||
