#include "sysdefs.h"
Use pthread_sigmask() instead of sigprocmask() when pthreads are enabled.

#include "mythread.h"
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.
2011-04-12 05:42:37 -04:00
Add LZMA_API to liblzma API headers. It's useful at least on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h has to be #included separately where needed.

Oh well, big messy commit again. Some highlights: - Updated to the latest, probably final file format version. - Command line tool reworked to not use threads anymore. Threading will probably go into liblzma anyway. - Memory usage limit is now about 30 % for uncompression and about 90 % for compression. - Progress indicator with --verbose - Simplified --help and full --long-help - Upgraded to the last LGPLv2.1+ getopt_long from gnulib. - Some bug fixes

Various changes. Separate a few reusable components from XZ Utils specific code. The reusable code is now in "tuklib" modules. A few more could be separated still, e.g. bswap.h. Fix some bugs in lzmainfo. Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol for help. Add OpenVMS support into physmem. Add a few #ifdefs to ease building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the original patch.

xz: Multiple fixes. The code assumed that printing numbers with thousand separators and decimal points would always produce only US-ASCII characters. This was used for buffer sizes (with snprintf(), no overflows) and aligning columns of the progress indicator and --list. That assumption was wrong (e.g. LC_ALL=fi_FI.UTF-8 with glibc), so multibyte character support was added in this commit. The old way is used if the operating system doesn't have enough multibyte support (e.g. lacks wcwidth()). The sizes of buffers were increased to accomodate multibyte characters. I don't know how big they should be exactly, but they aren't used for anything critical, so it's not too bad. If they still aren't big enough, I hopefully get a bug report. snprintf() takes care of avoiding buffer overflows. Some static buffers were replaced with buffers allocated on stack. double_to_str() was removed. uint64_to_str() and uint64_to_nicestr() now share the static buffer and test for thousand separator support. Integrity check names "None" and "Unknown-N" (2 <= N <= 15) were marked to be translated. I had forgot these, plus they wouldn't have worked correctly anyway before this commit, because printing tables with multibyte strings didn't work. Thanks to Marek Černocký for reporting the bug about misaligned table columns in --list output.

xz: Add support for OpenBSD's pledge() sandbox.

#if defined(HAVE_CAPSICUM) || defined(HAVE_PLEDGE)
xz: Add support for sandboxing with Capsicum. The sandboxing is used conditionally as described in main.c. This isn't optimal but it was much easier to implement than a full sandboxing solution and it still covers the most common use cases where xz is writing to standard output. This should have practically no effect on performance even with small files as fork() isn't needed. C and locale libraries can open files as needed. This has been fine in the past, but it's a problem with things like Capsicum. io_sandbox_enter() tries to ensure that various locale-related files have been loaded before cap_enter() is called, but it's possible that there are other similar problems which haven't been seen yet. Currently Capsicum is available on FreeBSD 10 and later and there is a port to Linux too. Thanks to Loganaden Velvindron for help.

xz: Make xz buildable even when encoders or decoders are disabled. The patch is quite long but it's mostly about adding new #ifdefs to omit code when encoders or decoders have been disabled. This adds two new #defines to config.h: HAVE_ENCODERS and HAVE_DECODERS.
