Lasse Collin 80a1a8bb83 CMake: Add xz symlinks.
These are a minor thing especially since the xz build has
some real problems still like lack of large file support
on 32-bit systems but I'll commit this since the code exists.

Thanks to Jia Tan.

Lasse Collin a93e235d7c Translations: Add Portuguese translation.
Jia Tan made white-space changes and also changed "Language: pt_BR\n"
to pt. The translator wasn't reached so I'm hoping these changes
are OK and will commit it without translator's approval.

Thanks to Pedro Albuquerque and Jia Tan.

Lasse Collin e7cf5a946f Translations: Add Serbian translation.
Quite a few white-space changes were made by Jia Tan to make
this look good. Contacting the translator didn't succeed so
I'm committing this without getting translator's approval.

Thanks to Мирослав Николић (Miroslav Nikolic) and Jia Tan.

Lasse Collin 65217eaf6b Translations: Rebuild cs.po to avoid incorrect fuzzy strings.
"make dist" updates the .po files and the fuzzy strings would
result in multiple very wrong translations.
2022-08-22 18:06:37 +03:00

Lasse Collin 43e09c62e7 Translations: Add hu, zh_CN, and zh_TW.
I made a few white space changes to these without getting them
approved by the translation teams. (I tried to contact the hu and
zh_TW teams but didn't succeed. I didn't contact the zh_CN team.)

Lasse Collin 982b6b198a Translations: Update vi.po to match the file from the TP.
The translated strings haven't been updated but word wrapping
is different.
2022-08-22 18:06:37 +03:00
Lasse Collin 801f39691f Translations: Add fi and pt_BR, and update de, fr, it, and pl.
The German translation isn't identical to the file in
the Translation Project but the changes (white space changes
only) were approved by the translator Mario Blättermann.

Lasse Collin 02a777f9c4 xz: Revise --info-memory output.
The strings could be more descriptive but it's good
to have some version of this committed now.

--robot mode wasn't changed yet.

Lasse Collin f864f6d42e xz: Update the man page for threaded decompression and memlimits.
This documents the changes made in commits
6c6da57ae2,
cad299008c, and
898faa9728.

The --info-memory bit hasn't been finished yet
even though it's already mentioned in this commit
under --memlimit-mt-decompress and --threads.

Lasse Collin d13bfcc005 Build: Include the CMake files in the distribution.
This was supposed to be done in 2020 with 5.2.5 release
already but it was noticed only today. 5.2.5 and 5.2.6
even mention experiemental CMake support in the NEWS entries.

Thanks to Olivier B. for reporting the problem.

Lasse Collin e66787bcfe Windows: Fix broken liblzma.dll build with Visual Studio project files.
The bug was introduced in 352ba2d69a
"Windows: Fix building of resource files when config.h isn't used."

That commit fixed liblzma.dll build with CMake while keeping it
working with Autotools on Windows but the VS project files were
forgotten.

I haven't tested these changes.

Thanks to Olivier B. for reporting the bug and for the initial patch.

Lasse Collin c4e8e5fb31 liblzma: Threaded decoder: Improve LZMA_FAIL_FAST when LZMA_FINISH is used.
It will now return LZMA_DATA_ERROR (not LZMA_OK or LZMA_BUF_ERROR)
if LZMA_FINISH is used and there isn't enough input to finish
decoding the Block Header or the Block. The use of LZMA_DATA_ERROR
is simpler and the less risky than LZMA_BUF_ERROR but this might
be changed before 5.4.0.

Lasse Collin 352672732c Build: Start the generated ChangeLog from around 5.2.0 instead of 5.0.0.
This makes ChangeLog smaller.

Lasse Collin 6f6d11225d Translations: Change the copyright comment string to use with po4a.
This affects the second line in po4a/xz-man.pot. The man pages of
xzdiff, xzgrep, and xzmore are from GNU gzip and under GNU GPLv2+
while the rest of the man pages are in the public domain.

Jia Tan 4d80b463a1 Build: Don't allow empty LIST in --enable-match-finders=LIST.
It's enforced only when a match finder is needed, that is,
when LZMA1 or LZMA2 encoder is enabled.

Lasse Collin d796b6d7fd xzgrep man page: Document exit statuses. 2022-07-19 23:19:49 +03:00
Lasse Collin 923bf96b55 xzgrep: Improve error handling, especially signals.
xzgrep wouldn't exit on SIGPIPE or SIGQUIT when it clearly
should have. It's quite possible that it's not perfect still
but at least it's much better.

If multiple exit statuses compete, now it tries to pick
the largest of value.

Some comments were added.

The exit status handling of signals is still broken if the shell
uses values larger than 255 in $? to indicate that a process
died due to a signal ***and*** their "exit" command doesn't take
this into account. This seems to work well with the ksh and yash
versions I tried. However, there is a report in gzip/zgrep that
OpenSolaris 5.11 (not 5.10) has a problem with "exit" truncating
the argument to 8 bits:

    https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22900#25

Such a bug would break xzgrep but I didn't add a workaround
at least for now. 5.11 is old and I don't know if the problem
exists in modern descendants, or if the problem exists in other
ksh implementations in use.

Lasse Collin a648978b20 xzgrep: Make the fix for ZDI-CAN-16587 more robust.
I don't know if this can make a difference in the real world
but it looked kind of suspicious (what happens with sed
implementations that cannot process very long lines?).
At least this commit shouldn't make it worse.
2022-07-19 00:10:55 +03:00
Lasse Collin bd7b290f3f xzgrep: Use grep -H --label when available (GNU, *BSDs).
It avoids the use of sed for prefixing filenames to output lines.
Using sed for that is slower and prone to security bugs so now
the sed method is only used as a fallback.

This also fixes an actual bug: When grepping a binary file,
GNU grep nowadays prints its diagnostics to stderr instead of
stdout and thus the sed-method for prefixing the filename doesn't
work. So with this commit grepping binary files gives reasonable
output with GNU grep now.

This was inspired by zgrep but the implementation is different.
2022-07-18 22:06:10 +03:00
Lasse Collin b56729af9f xzgrep: Use -e to specify the pattern to grep.
Now we don't need the separate test for adding the -q option
as it can be added directly in the two places where it's needed.
2022-07-18 21:10:25 +03:00
Lasse Collin bad61b5997 Scripts: Use printf instead of echo in a few places.
It's a good habbit as echo has some portability corner cases
when the string contents can be anything.
2022-07-18 19:18:48 +03:00
Lasse Collin 6a4a4a7d26 xzgrep: Add more LC_ALL=C to avoid bugs with multibyte characters.
Also replace one use of expr with printf.

The rationale for LC_ALL=C was already mentioned in
69d1b3fc29 that fixed a security
issue. However, unrelated uses weren't changed in that commit yet.

POSIX says that with sed and such tools one should use LC_ALL=C
to ensure predictable behavior when strings contain byte sequences
that aren't valid multibyte characters in the current locale. See
under "Application usage" in here:

https://pubs.opengroup.org/onlinepubs/9699919799/utilities/sed.html

With GNU sed invalid multibyte strings would work without this;
it's documented in its Texinfo manual. Some other implementations
aren't so forgiving.

Lasse Collin b48f9d615f xzgrep: Fix parsing of certain options.
Fix handling of "xzgrep -25 foo" (in GNU grep "grep -25 foo" is
an alias for "grep -C25 foo"). xzgrep would treat "foo" as filename
instead of as a pattern. This bug was fixed in zgrep in gzip in 2012.

Add -E, -F, -G, and -P to the "no argument required" list.

Add -X to "argument required" list. It is an
intentionally-undocumented GNU grep option so this isn't
an important option for xzgrep but it seems that other grep
implementations (well, those that I checked) don't support -X
so I hope this change is an improvement still.

grep -d (grep --directories=ACTION) requires an argument. In
contrast to zgrep, I kept -d in the "no argument required" list
because it's not supported in xzgrep (or zgrep). This way
"xzgrep -d" gives an error about option being unsupported instead
of telling that it requires an argument. Both zgrep and xzgrep
tell that it's unsupported if an argument is specified.

Add comments.

Lasse Collin 9595a3119b liblzma: Add optional autodetection of LZMA end marker.
Turns out that this is needed for .lzma files as the spec in
LZMA SDK says that end marker may be present even if the size
is stored in the header. Such files are rare but exist in the
real world. The code in liblzma is so old that the spec didn't
exist in LZMA SDK back then and I had understood that such
files weren't possible (the lzma tool in LZMA SDK didn't
create such files).

This modifies the internal API so that LZMA decoder can be told
if EOPM is allowed even when the uncompressed size is known.
It's allowed with .lzma and not with other uses.

Thanks to Karl Beldan for reporting the problem.
