Lasse Collin bd334ae56a Add NEWS for 5.2.7 (forgotten cherry-pick from v5.2). 2022-11-11 13:27:06 +02:00
Lasse Collin 3c7860cf49 xzdiff: Add support for .lz files.
The other scripts don't need changes for .lz support because
in those scripts it is enough that xz supports .lz.
2022-11-11 13:16:21 +02:00
Lasse Collin d76c752a6d Scripts: Ignore warnings from xz.
In practice this means making the scripts work when
the input files have an unsupported check type which
isn't a problem in practice unless support for
some check types has been disabled at build time.

Lasse Collin 6552535afd Translations: Rename poa4/fr_FR.po to po4a/fr.po.
That's how it is preferred at the Translation Project.
On my system /usr/share/man/fr_FR doesn't contain any
other man pages than XZ Utils while /usr/share/man/fr
has quite a few, so this will fix that too.

Thanks to Benno Schulenberg from the Translation Project.

Lasse Collin 0918159ce4 xz: Update the man page about BCJ filters, including upcoming --arm64.
The --arm64 isn't actually implemented yet in the form
described in this commit.

Thanks to Jia Tan.

Lasse Collin ba2ae3596f xz: Add --arm64 to --long-help and omit endianness from ARM(-Thumb).
Modern 32-bit ARM in big endian mode use little endian for
instruction encoding still, so the filters work on such
executables too. It's likely less confusing for users this way.

The --arm64 option hasn't been implemented yet (there is
--experimental-arm64 but it's different). The --arm64 option
is added now anyway because this is the likely result and the
strings need to be ready for translators.

Thanks to Jia Tan.

Lasse Collin 3176f992c5 xz: Add .lz (lzip) decompression support.
If configured with --disable-lzip-decoder then --long-help will
still list `lzip' in --format but I left it like that since
due to translations it would be messy to have two help strings.
Features are disabled only in special situations so wrong help
in such a situation shouldn't matter much.

Thanks to Michał Górny for the original patch.

Lasse Collin 034086e1ae liblzma: Add .lz support to lzma_auto_decoder().
Thanks to Michał Górny for the original patch.
2022-11-09 14:25:26 +02:00
Lasse Collin 0538db038f liblzma: Add .lz (lzip) decompression support (format versions 0 and 1).
Support for format version 0 was removed from lzip 1.18 for some
reason. .lz format version 0 files are rare (and old) but some
source packages were released in this format, and some people might
have personal files in this format too. It's very little extra code
to support it along side format version 1 so this commits adds
support for both.

The Sync Flush marker extentension to the original .lz format
version 1 isn't supported. It would require changes to the
LZMA decoder itself. Such files are very rare anyway.

See the API doc for lzma_lzip_decoder() for more details about
the .lz format support.

Thanks to Michał Górny for the original patch.

Lasse Collin 724285dadb xz: Add comments about stdin and src_st.st_size.
"xz -v < regular_file > out.xz" doesn't display the percentage
and estimated remaining time because it doesn't even try to
check the input file size when input is read from stdin.
This could be improved but for now there's just a comment
to remind about it.
2022-11-09 14:10:52 +02:00
Lasse Collin f723eec68b xz: Fix displaying of file sizes in progress indicator in passthru mode.
It worked for one input file since the counters are zero when
xz starts but they weren't reset when starting a new file in
passthru mode. For example, if files A, B, and C are one byte each,
then "xz -dcvf A B C" would show file sizes as 1, 2, and 3 bytes
instead of 1, 1, and 1 byte.

Lasse Collin 69265d0f22 xz: Add a comment why --to-stdout is not in --help.
It is on the man page still.

Lasse Collin 026a5897c7 xz: Initialize the pledge(2) sandbox at the very beginning of main().
It feels better that the initializations are sandboxed too.
They don't do anything that the pledge() call wouldn't allow.

Lasse Collin 49a59f6ca0 xz: Extend --robot --info-memory output.
Now it includes everything that the human-readable --info-memory shows.
2022-11-07 22:51:16 +02:00
Lasse Collin 5e2450c75c liblzma: Include cached memory in reported memusage in threaded decoder.
This affects lzma_memusage() and lzma_memlimit_set() when used
with the threaded decompressor. Now all allocations are reported
by lzma_memusage() (so it's not misleading) and lzma_memlimit_set()
cannot lower the limit below that value.

The alternative would have been to allow lowering the limit if
doing so is possible by freeing the cached memory but since
the primary use case of lzma_memlimit_set() is to increase
memlimit after LZMA_MEMLIMIT_ERROR this simple approach
was selected.

The cached memory was always included when enforcing
the memory usage limit while decoding.

Thanks to Jia Tan.

This should be smaller too since it avoids the string constants.

Lasse Collin e53e0e2186 Windows: Fix mythread_once() macro with Vista threads.
Don't call InitOnceComplete() if initialization was already done.

So far mythread_once() has been needed only when building
with --enable-small. windows/build.bash does this together
with --disable-threads so the Vista-specific mythread_once()
is never needed by those builds. VS project files or
CMake-builds don't support HAVE_SMALL builds at all.

Lasse Collin 05c72de06f Tests: test_files.sh: Make it not fail if features were disabled at build.
It now tries to test as many files as easily possible.
The exit status indicates skipping if any of the files were
skipped. This way it is easy to notice if something is being
skipped when it isn't expected.

Lasse Collin b3459327a5 Tests: test_files.sh: Suppress an expected warning from the log.
xz (but not xzdec) will normally warn about unsupported check
but since we are testing specifically such a file, it's better
to silence that warning so that it doesn't look suspicious in
test_files.sh.log.

The use of -q and -Q in xzdec is just for consistency and
doesn't affect the result at least for now.

Lasse Collin a4b214b93a Build: Use AC_CONFIG_HEADERS instead of the ancient AC_CONFIG_HEADER.
We require Autoconf >= 2.69 and that has AC_CONFIG_HEADERS.

There is a warning about AC_PROG_CC_C99 being obsolete but
it cannot be removed because it is needed with Autoconf 2.69.

Lasse Collin 59c4d6e139 Build: Add configure option --disable-microlzma.
MicroLZMA was made for EROFS and used by erofs-utils.
It might be used by something else in the future but
those wanting a smaller build for specific situations
can now disable this rarely-needed feature.

Lasse Collin 054ccd6d14 xz: Fix --single-stream with an empty .xz Stream.
Example:

    $ xz -dc --single-stream good-0-empty.xz
    xz: good-0-empty.xz: Internal error (bug)

The code, that is tries to catch some input file issues early,
didn't anticipate LZMA_STREAM_END which is possible in that
code only when --single-stream is used.

Lasse Collin 563288ea70 xz: Add support for OpenBSD's pledge() sandbox. 2022-10-25 21:30:48 +03:00
Lasse Collin f9913e8ee2 xz: Fix decompressor behavior if input uses an unsupported check type.
Now files with unsupported check will make xz display
a warning, set the exit status to 2 (unless --no-warn is used),
and then decompress the file normally. This is how it was
supposed to work since the beginning but this was broken by
the commit 231c3c7098, that is,
a little before 5.0.0 was released. The buggy behavior displayed
a message, set exit status 1 (error), and xz didn't attempt to
to decompress the file.

This doesn't matter today except for special builds that disable
CRC64 or SHA-256 at build time (but such builds should be used
in special situations only). The bug matters if new check type
is added in the future and an old xz version is used to decompress
such a file; however, it's likely that such files would use a new
filter too and an old xz wouldn't be able to decompress the file
anyway.

The first hunk in the commit is the actual fix. The second hunk
is a cleanup since LZMA_TELL_ANY_CHECK isn't used in xz.

There is a test file for unsupported check type but it wasn't
used by test_files.sh, perhaps due to different behavior between
xz and the simpler xzdec.

Lasse Collin 8b46ae8cde xz: Refactor to remove is_empty_filename().
Long ago it was used in list.c too but nowadays it's needed
only in io_open_src() so it's nicer to avoid a separate function.
