2010-09-10xz: Multiple fixes.Lasse Collin1-0/+30
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.
2010-05-10Updates to tuklib_physmem and tuklib_cpucores.Lasse Collin2-8/+97
Don't use #error to generate compile error, because some compilers actually don't take it as an error. This fixes tuklib_physmem on IRIX. Fix incorrect error check for sysconf() return values. Add AIX, HP-UX, and Tru64 specific code to detect the amount RAM. Add HP-UX specific code to detect the number of CPU cores. Thanks a lot to Peter O'Gorman for initial patches, testing, and debugging these fixes.
2010-01-12Add IRIX-specific code to tuklib_physmem and tuklib_cpucores.Lasse Collin2-3/+30
This is untested but it will get tested soon and, if needed, fixed before 5.0.0. Thanks to Stuart Shelton.
2009-11-20Update tuklib_cpucores.m4 and tuklib_physmem.m4 from tuklib,Lasse Collin2-36/+45
which now use AC_CACHE_CHECK. Using the cache variable, configure now warns if there is no method to detect the amount of RAM and recommends using --enable-assume-ram.
2009-10-04Use a tuklib module for integer handling.Lasse Collin1-0/+74
This replaces bswap.h and integer.h. The tuklib module uses <byteswap.h> on GNU, <sys/endian.h> on *BSDs and <sys/byteorder.h> on Solaris, which may contain optimized code like inline assembly.
2009-09-19Various changes.Lasse Collin5-118/+215
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.
2009-08-29Fix sysctl() usage.Lasse Collin2-2/+2
This fixes build on *BSDs and Darwin. Thanks to Jukka Salmi for the patches. Richard Koch reported the problem too.
2009-07-05Major update to the xzgrep and other scripts based onLasse Collin1-0/+63
the latest versions found from gzip CVS repository. configure will try to find a POSIX shell to be used by the scripts. This should ease portability on systems which have pre-POSIX /bin/sh. xzgrep and xzdiff support .xz, .lzma, .gz, and .bz2 files. xzmore and xzless support only .xz and .lzma files. The name of the xz executable used in these scripts is now correct even if --program-transform-name has been used.
2009-03-18Fix wrong macro names in lc_cpucores.m4 and cpucores.h.Lasse Collin1-2/+2
Thanks to Bert Wesarg.
2009-03-01Test for Linux-specific sysinfo() only on Linux systems.Lasse Collin1-9/+19
Some other systems have sysinfo() with different semantics.
2009-03-01Fix the Autoconf test for getopt_long replacement.Lasse Collin1-0/+4
It was broken by e114502b2bc371e4a45449832cb69be036360722.
2009-02-14Cleanups to the code that detects the amount of RAM andLasse Collin2-0/+131
the number of CPU cores. Added support for using sysinfo() on Linux systems whose libc lacks appropriate sysconf() support (at least dietlibc). The Autoconf macros were split into separate files, and CPU core count detection was moved from hardware.c to cpucores.h. The core count isn't used for anything real for now, so a problematic part in process.c was commented out.

2008-11-19Oh well, big messy commit again. Some highlights:Lasse Collin1-40/+24
- 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
2008-03-24Replaced the range decoder optimization that used arithmeticLasse Collin1-36/+0
right shift with as fast version that doesn't need arithmetic right shift. Removed the related check from configure.ac.
2008-03-22Added autoconf check to detect if we can use arithmeticLasse Collin1-0/+36
right shift for optimizations.
