Lasse Collin f76f7516d6 xzless: Rename unused variables to silence static analysers.
In this particular case I don't see this affecting readability
of the code.

Thanks to Pavel Raiskup.

Lasse Collin 3cbcaeb07e liblzma: Remove an always-true condition from lzma_index_cat().
This should help static analysis tools to see that newg
isn't leaked.

Thanks to Pavel Raiskup.

In C++11, the `throw()` specifier is deprecated and `noexcept` is
preffered instead.

In most cases it was harmless but it could affect some

Lasse Collin a015cd1f90 xz: Fix "xz --list --robot missing_or_bad_file.xz".
It ended up printing an uninitialized char-array when trying to
print the check names (column 7) on the "totals" line.

This also changes the column 12 (minimum xz version) to
50000002 (xz 5.0.0) instead of 0 when there are no valid
input files.

Thanks to kidmin for the bug report.

Lasse Collin bba477257d xz: Use POSIX_FADV_RANDOM for in "xz --list" mode.
xz --list is random access so POSIX_FADV_SEQUENTIAL was clearly
wrong.

Lasse Collin 310d19816d liblzma: Make lzma_index_decoder_init() visible to other liblzma funcs.
This is to allow other functions to use it without going
via the public API (lzma_index_decoder()).
2017-03-30 20:03:05 +03:00
Lasse Collin a27920002d liblzma: Add generic support for input seeking (LZMA_SEEK).
Also mention LZMA_SEEK in xz/message.c to silence a warning.

Lasse Collin a0b1dda409 liblzma: Fix lzma_memlimit_set(strm, 0).
The 0 got treated specially in a buggy way and as a result
the function did nothing. The API doc said that 0 was supposed
to return LZMA_PROG_ERROR but it didn't.

Now 0 is treated as if 1 had been specified. This is done because
0 is already used to indicate an error from lzma_memlimit_get()
and lzma_memusage().

In addition, lzma_memlimit_set() no longer checks that the new
limit is at least LZMA_MEMUSAGE_BASE. It's counter-productive
for the Index decoder and was actually needed only by the
auto decoder. Auto decoder has now been modified to check for
LZMA_MEMUSAGE_BASE.

Lasse Collin 84462afaad liblzma: Similar memlimit fix for stream_, alone_, and auto_decoder. 2017-03-30 19:16:55 +03:00
Lasse Collin cbc7401793 liblzma: Fix handling of memlimit == 0 in lzma_index_decoder().
It returned LZMA_PROG_ERROR, which was done to avoid zero as
the limit (because it's a special value elsewhere), but using
LZMA_PROG_ERROR is simply inconvenient and can cause bugs.

The fix/workaround is to treat 0 as if it were 1 byte. It's
effectively the same thing. The only weird consequence is
that then lzma_memlimit_get() will return 1 even when 0 was
specified as the limit.

This fixes a very rare corner case in xz --list where a specific
memory usage limit and a multi-stream file could print the
error message "Internal error (bug)" instead of saying that
the memory usage limit is too low.

Lasse Collin d4a0462abe liblzma: Avoid multiple definitions of lzma_coder structures.
Only one definition was visible in a translation unit.
It avoided a few casts and temp variables but seems that
this hack doesn't work with link-time optimizations in compilers
as it's not C99/C11 compliant.

Lasse Collin df8f446e3a tuklib_cpucores: Add support for sched_getaffinity().
It's available in glibc (GNU/Linux, GNU/kFreeBSD). It's better
than sysconf(_SC_NPROCESSORS_ONLN) because sched_getaffinity()
gives the number of cores available to the process instead of
the total number of cores online.

As a side effect, this commit fixes a bug on GNU/kFreeBSD where
configure would detect the FreeBSD-specific cpuset_getaffinity()
but it wouldn't actually work because on GNU/kFreeBSD it requires
using -lfreebsd-glue when linking. Now the glibc-specific function
will be used instead.

Thanks to Sebastian Andrzej Siewior for the original patch
and testing.

Lasse Collin 446e4318fa xz: Fix copying of timestamps on Windows.
xz used to call utime() on Windows, but its result gets lost
on close(). Using _futime() seems to work.

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.
