Lasse Collin 124eb69c78 Windows: Add Windows support to tuklib_cpucores().
It is used for Cygwin too. I'm not sure if that is
a good or bad idea.

Thanks to Vincent Torri.

Lasse Collin ab25b82a91 Build: Upgrade m4/acx_pthread.m4 to the latest version. 2012-05-24 18:33:54 +03:00
Lasse Collin db33117cc8 Build: Upgrade m4/acx_pthread.m4 to the latest version.
It was renamed to ax_pthread.m4 in Autoconf Archive.

Lasse Collin bb0b1004f8 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.

Lasse Collin 6548e30465 Updates to tuklib_physmem and tuklib_cpucores.
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.

Lasse Collin 153c7740c5 Add IRIX-specific code to tuklib_physmem and tuklib_cpucores.
This is untested but it will get tested soon and, if needed,
fixed before 5.0.0.

Thanks to Stuart Shelton.

Lasse Collin c74c132f7f Update tuklib_cpucores.m4 and tuklib_physmem.m4 from tuklib,
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.

Lasse Collin ebfb2c5e1f Use a tuklib module for integer handling.
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.

Lasse Collin e599bba421 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.

Lasse Collin 27414daadf Fix sysctl() usage.
This fixes build on *BSDs and Darwin.

Thanks to Jukka Salmi for the patches.
Richard Koch reported the problem too.

Lasse Collin 96e4b257e1 Major update to the xzgrep and other scripts based on
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.

Lasse Collin 390e69887f Fix wrong macro names in lc_cpucores.m4 and cpucores.h.
Thanks to Bert Wesarg.

Lasse Collin 0df9299e24 Test for Linux-specific sysinfo() only on Linux systems.
Some other systems have sysinfo() with different semantics.

Lasse Collin 63df14c57d Fix the Autoconf test for getopt_long replacement.
It was broken by e114502b2b.
2009-03-01 08:58:41 +02:00
Lasse Collin 3084d662d2 Cleanups to the code that detects the amount of RAM and
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.

Lasse Collin e114502b2b 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

Lasse Collin 641998c3e1 Replaced the range decoder optimization that used arithmetic
right shift with as fast version that doesn't need
arithmetic right shift. Removed the related check from
configure.ac.
2008-03-24 16:38:40 +02:00
Lasse Collin 03e0e8a0d7 Added autoconf check to detect if we can use arithmetic
right shift for optimizations.
