Lasse Collin ab50ae3ef4 liblzma: Fix invalid free() in the threaded encoder.
It was triggered if initialization failed e.g. due to
running out of memory.

Thanks to Arkadiusz Miskiewicz.

Lasse Collin 6b620a0f08 liblzma: Fix a deadlock in the threaded encoder.
It was triggered when reinitializing the encoder,
e.g. when encoding two files.

Lasse Collin e9ed88126e Run the scripts with the correct shell in test_scripts.sh.
The scripts are now made executable in the build tree.
This way the scripts can be run like programs in
test_scripts.sh. Previously test_scripts.sh always
used sh but it's not correct if @POSIX_SHELL@ is set
to something else by configure.

Thanks to Jonathan Nieder for the patch.

Lasse Collin 1c673e5681 Fix exit status of "xzdiff foo.xz bar.xz".
xzdiff was clobbering the exit status from diff in a case
statement used to analyze the exit statuses from "xz" when
its operands were two compressed files. Save and restore
diff's exit status to fix this.

The bug is inherited from zdiff in GNU gzip and was fixed
there on 2009-10-09.

Thanks to Jonathan Nieder for the patch and
to Peter Pallinger for reporting the bug.

Lasse Collin bd35d903a0 liblzma: Use symbol versioning.
Symbol versioning is enabled by default on GNU/Linux,
other GNU-based systems, and FreeBSD.

I'm not sure how stable this is, so it may need
backward-incompatible changes before the next release.

The idea is that alpha and beta symbols are considered
unstable and require recompiling the applications that
use those symbols. Once a symbol is stable, it may get
extended with new features in ways that don't break
compatibility with older ABI & API.

The mydist target runs validate_map.sh which should
catch some probable problems in liblzma.map. Otherwise
I would forget to update the map file for new releases.

of the uninitialized filters array.

Lasse Collin bba37df2c9 Add French translation.
It is known that the BCJ filter --help text is only
partially translated.
2011-05-21 16:28:44 +03:00
Lasse Collin 4161d76349 xz: Translate also the string used to print the program name.
French needs a space before a colon, e.g. "xz : foo error".

Lasse Collin b94aa0c838 liblzma: Try to use SHA-256 from the operating system.
If the operating system libc or other base libraries
provide SHA-256, use that instead of our own copy.
Note that this doesn't use OpenSSL or libgcrypt or
such libraries to avoid creating dependencies to
other packages.

This supports at least FreeBSD, NetBSD, OpenBSD, Solaris,
MINIX, and Darwin. They all provide similar but not
identical SHA-256 APIs; everyone is a little different.

Thanks to Wim Lewis for the original patch, improvements,
and testing.

Lasse Collin ec7106309c Build: Fix initialization of enable_check_* variables in configure.ac.
This doesn't matter much in practice since it is unlikely
that anyone would have such environment variable names.

Thanks to Wim Lewis.

Lasse Collin 7a480e4859 xz: Fix input file position when --single-stream is used.
Now the following works as you would expect:

    echo foo | xz > foo.xz
    echo bar | xz >> foo.xz
    ( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz

Note that it doesn't work if the input is not seekable
or if there is Stream Padding between the concatenated
.xz Streams.

Lasse Collin e4622df9ab Update THANKS. 2011-04-19 09:55:06 +03:00
Lasse Collin 9c1b05828a Fix portability problems in mythread.h.
Use gettimeofday() if clock_gettime() isn't available
(e.g. Darwin).

The test for availability of pthread_condattr_setclock()
and CLOCK_MONOTONIC was incorrect. Instead of fixing the
#ifdefs, use an Autoconf test. That way if there exists a
system that supports them but doesn't specify the matching
POSIX #defines, the features will still get detected.

Don't try to use pthread_sigmask() on OpenVMS. It doesn't
have that function.

Guard mythread.h against being #included multiple times.

Lasse Collin 9a4377be0d Put the unstable APIs behind #ifdef LZMA_UNSTABLE.
This way people hopefully won't complain if these APIs
change and break code that used an older API.

Lasse Collin de678e0c92 liblzma: Add lzma_stream_encoder_mt() for threaded compression.
This is the simplest method to do threading, which splits
the uncompressed data into blocks and compresses them
independently from each other. There's room for improvement
especially to reduce the memory usage, but nevertheless,
this is a good start.
