Lasse Collin ac398c3baf liblzma: Disable external SHA-256 by default.
This is the sane thing to do. The conflict with OpenSSL
on some OSes and especially that the OS-provided versions
can be significantly slower makes it clear that it was
a mistake to have the external SHA-256 support enabled by
default.

Those who want it can now pass --enable-external-sha256 to
configure. INSTALL was updated with notes about OSes where
this can be a bad idea.

The SHA-256 detection code in configure.ac had some bugs that
could lead to a build failure in some situations. These were
fixed, although it doesn't matter that much now that the
external SHA-256 is disabled by default.

MINIX >= 3.2.0 uses NetBSD's libc and thus has SHA256_Init
in libc instead of libutil. Support for the libutil version
was removed.

Lasse Collin 473ef0dc69 Build: Avoid SHA256_Init on FreeBSD and MINIX 3.
On FreeBSD 10 and older, SHA256_Init from libmd conflicts
with libcrypto from OpenSSL. The OpenSSL version has
different sizeof(SHA256_CTX) and it can cause weird
problems if wrong SHA256_Init gets used.

Looking at the source, MINIX 3 seems to have a similar issue but
I'm not sure. To be safe, I disabled SHA256_Init on MINIX 3 too.

NetBSD has SHA256_Init in libc and they had a similar problem,
but they already fixed it in 2009.

Thanks to Jim Wilcoxson for the bug report that helped
in finding the problem.

Lasse Collin 14115f84a3 liblzma: Make Valgrind happier with optimized (gcc -O2) liblzma.
When optimizing, GCC can reorder code so that an uninitialized
value gets used in a comparison, which makes Valgrind unhappy.
It doesn't happen when compiled with -O0, which I tend to use
when running Valgrind.

Thanks to Rich Prohaska. I remember this being mentioned long
ago by someone else but nothing was done back then.

Lasse Collin f4c95ba94b liblzma: Rename lzma_presets.c back to lzma_encoder_presets.c.
It would be too annoying to update other build systems
just because of this.

Lasse Collin c7bc20a6f3 Build: Disable xzdec, lzmadec, and lzmainfo when they cannot be built.
They all need decoder support and if that isn't available,
there's no point trying to build them.

Lasse Collin cb3111e3ed 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.
2015-11-03 20:29:33 +02:00
Lasse Collin 4cc584985c Build: Build LZMA1/2 presets also when only decoder is wanted.
People shouldn't rely on the presets when decoding raw streams,
but xz uses the presets as the starting point for raw decoder
options anyway.

lzma_encocder_presets.c was renamed to lzma_presets.c to
make it clear it's not used solely by the encoder code.
2015-11-03 18:06:40 +02:00
Lasse Collin 23ed1d4148 Build: Fix configure to handle LZMA1 dependency with LZMA2.
Now it gives an error if LZMA1 encoder/decoder is missing
when LZMA2 encoder/decoder was requested. Even better would
be LZMA2 implicitly enabling LZMA1 but it would need more code.
2015-11-03 17:54:48 +02:00
Lasse Collin b0bc3e0385 Build: Don't omit lzma_cputhreads() unless using --disable-threads.
Previously it was omitted if encoders were disabled
with --disable-encoders. It didn't make sense and
it also broke the build.

Lasse Collin c6bf438ab3 liblzma: Fix a build failure related to external SHA-256 support.
If an appropriate header and structure were found by configure,
but a library with a usable SHA-256 functions wasn't, the build
failed.

Lasse Collin 3bf857edfe liblzma: Fix a memory leak in error path of lzma_index_dup().
lzma_index_dup() calls index_dup_stream() which, in case of
an error, calls index_stream_end() to free memory allocated
by index_stream_init(). However, it illogically didn't
actually free the memory. To make it logical, the tree
handling code was modified a bit in addition to changing
index_stream_end().

Thanks to Evan Nemerson for the bug report.

Hauke Henningsen 397fcc0946 Update German translation, mostly wrt orthography
Provide an update of the German translation.
* A lot of compound words were previously written with spaces, while
  German orthography is relatively clear in that the components
  should not be separated.
* When referring to the actual process of (de)compression rather than the
  concept, replace “(De-)Kompression” with “(De-)Komprimierung”.
  Previously, both forms were used in this context and are now used in a
  manner consistent with “Komprimierung” being more likely to refer to
  a process.
* Consistently translate “standard input”/“output”
* Use “Zeichen” instead of false friend “Charakter” for “character”
* Insert commas around relative clauses (as required in German)
* Some other minor corrections
* Capitalize “ß” as “ẞ”
* Consistently start option descriptions in --help with capital letters

Acked-By: Andre Noll <maan@tuebingen.mpg.de>

* Update after msgmerge

them all to use "cygwin". Shouldn't affect anything in practice.

Andre Noll 9b02a4ffda Fix typo in German translation.
As pointed out by Robert Pollak, there's a typo in the German
translation of the compression preset option (-0 ... -9) help text.
"The compressor" translates to "der Komprimierer", and the genitive
form is "des Komprimierers". The old word makes no sense at all.

Lasse Collin 6bd0349c58 Revert "xz: Use pipe2() if available."
This reverts commit 7a11c4a8e5.
It is a problem when libc has pipe2() but the kernel is too
old to have pipe2() and thus pipe2() fails. In xz it's pointless
to have a fallback for non-functioning pipe2(); it's better to
avoid pipe2() completely.

Thanks to Michael Fox for the bug report.

Lasse Collin 1238381143 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.

Lasse Collin 29a087fb5a Fix bugs and otherwise improve ax_check_capsicum.m4.
AU_ALIAS was removed because the new version is incompatible
with the old version.

It no longer checks for <sys/capability.h> separately.
It's enough to test for it as part of AC_CHECK_DECL.
The defines HAVE_CAPSICUM_SYS_CAPSICUM_H and
HAVE_CAPSICUM_SYS_CAPABILITY_H were removed as unneeded.
HAVE_SYS_CAPSICUM_H from AC_CHECK_HEADERS is enough.

It no longer does a useless search for the Capsicum library
if the header wasn't found.

Fixed a bug in ACTION-IF-FOUND (the first argument). Specifying
the argument omitted the default action but the given action
wasn't used instead.

AC_DEFINE([HAVE_CAPSICUM]) is now always called when Capsicum
support is found. Previously it was part of the default
ACTION-IF-FOUND which a custom action would override. Now
the default action only prepends ${CAPSICUM_LIB} to LIBS.

The documentation was updated.

Since there as no serial number, "#serial 2" was added.

Lasse Collin 3717885f9e Bump version to 5.3.0alpha and soname to 5.3.99.
The idea of 99 is that it looks a bit weird in this context.
For new features there's no API/ABI stability in devel versions.

Lasse Collin 25263fd9e7 Fix the detection of installed RAM on QNX.
The earlier version compiled but didn't actually work

Lasse Collin 4c544d2410 Fix CPU core count detection on QNX.
It tried to use sysctl() on QNX but
  - it broke the build because sysctl() needs -lsocket on QNX;
  - sysctl() doesn't work for detecting the core count on QNX
    even if it compiled.

sysconf() works. An alternative would have been to use
QNX-specific SYSPAGE_ENTRY(num_cpu) from <sys/syspage.h>.

Thanks to Ole André Vadla Ravnås.
