Lasse Collin 71b9380145 liblzma: Validate encoder arguments better. 
The biggest problem was that the integrity check type
wasn't validated, and e.g. lzma_easy_buffer_encode()
would create a corrupt .xz Stream if given an unsupported
Check ID. Luckily applications don't usually try to use
an unsupport Check ID, so this bug is unlikely to cause
many real-world problems.

Lasse Collin fb64a49243 liblzma: Make lzma_stream_encoder_init() static (second try). 
It's an internal function and it's not needed by
anything outside stream_encoder.c.

Lasse Collin a34730cf6a Revert "liblzma: Make lzma_stream_encoder_init() static." 
This reverts commit 352ac82db5.
I don't know what I was thinking.

Lasse Collin 9f0a806aef Revise mythread.h. 
This adds:

  - mythread_sync() macro to create synchronized blocks

  - mythread_cond structure and related functions
    and macros for condition variables with timed
    waiting using a relative timeout

  - mythread_create() to create a thread with all
    signals blocked

Some of these wouldn't need to be inline functions,
but I'll keep them this way for now for simplicity.

For timed waiting on a condition variable, librt is
now required on some systems to use clock_gettime().
configure.ac was updated to handle this.

Lasse Collin 9e807fe3fe DOS: Update the docs and include notes about 8.3 filenames. 2011-04-10 14:58:10 +03:00
Lasse Collin ebd54dbd6e xz/DOS: Add experimental 8.3 filename support. 
This is incompatible with the 8.3 support patch made by
Juan Manuel Guerrero. I think this one is nicer, but
I need to get feedback from DOS users before saying
that this is the final version of 8.3 filename support.

Lasse Collin cd4fe97852 xz/DOS: Be more careful with the destination file. 
Try to avoid overwriting the source file if --force is
used and the generated destination filename refers to
the source file. This can happen with 8.3 filenames where
extra characters are ignored.

If the generated output file refers to a special file
like "con" or "prn", refuse to write to it even if --force
is used.

Lasse Collin fca396b374 liblzma: Add missing #ifdefs to filter_common.c. 
Passing --disable-decoders to configure broke a few
encoders due to missing #ifdefs in filter_common.c.

Thanks to Jason Gorski for the patch.

Lasse Collin 335fe260a8 xz: Minor internal changes to handling of --threads. 
Now it always defaults to one thread. Maybe this
will change again if a threading method is added
that doesn't affect memory usage.

Lasse Collin 1ef3cf44a8 xz: Call lzma_end(&strm) before exiting if debugging is enabled. 2011-04-05 15:13:29 +03:00
Lasse Collin bd432015d3 liblzma: Fix a memory leak in stream_encoder.c. 
It leaks old filter options structures (hundred bytes or so)
every time the lzma_stream is reinitialized. With the xz tool,
this happens when compressing multiple files.

Lasse Collin c3f4995586 Tests: Add a new file to test empty LZMA2 streams. 2011-03-31 12:22:55 +03:00
Lasse Collin 0d21f49a80 liblzma: Fix decoding of LZMA2 streams having no uncompressed data. 
The decoder considered empty LZMA2 streams to be corrupt.
This shouldn't matter much with .xz files, because no encoder
creates empty LZMA2 streams in .xz. This bug is more likely
to cause problems in applications that use raw LZMA2 streams.

Lasse Collin 40277998cb Scripts: Better fix for xzgrep. 
Now it uses "grep -q".

Thanks to Gregory Margo.

Lasse Collin 2118733045 Updated THANKS. 2011-03-24 01:22:18 +02:00
Lasse Collin c7210d9a3f Scripts: Fix xzgrep -l. 
It didn't work at all. It tried to use the -q option
for grep, but it appended it after "--". This works
around it by redirecting to /dev/null. The downside
is that this can be slower with big files compared
to proper use of "grep -q".

Thanks to Gregory Margo.

Lasse Collin 923b22483b xz: Add --block-size=SIZE. 
This uses LZMA_FULL_FLUSH every SIZE bytes of input.

Lasse Collin 57597d42ca xz: Add --single-stream. 
This can be useful when there is garbage after the
compressed stream (.xz, .lzma, or raw stream).

Lasse Collin 96f94bc925 xz: Clean up suffix.c. 
struct suffix_pair isn't needed in compresed_name()
so get rid of it there.
 2011-02-06 20:16:14 +02:00
Lasse Collin 8930c7ae3f xz: Check if the file already has custom suffix when compressing. 
Now "xz -S .test foo.test" refuses to compress the
file because it already has the suffix .test. The man
page had it documented this way already.

Lasse Collin 03ebd1bbb3 xz: Fix --force on setuid/setgid/sticky and multi-hardlink files. 
xz didn't compress setuid/setgid/sticky files and files
with multiple hard links even with --force. This bug was
introduced in 23ac2c44c3.

Thanks to Charles Wilson.
