Thanks to Daniel Richard G.

Lasse Collin 43ce4ea7c7 Scripts: Put /usr/xpg4/bin to the beginning of PATH on Solaris.
This adds a configure option --enable-path-for-scripts=PREFIX
which defaults to empty except on Solaris it is /usr/xpg4/bin
to make POSIX grep and others available. The Solaris case had
been documented in INSTALL with a manual fix but it's better
to do this automatically since it is needed on most Solaris
systems anyway.

Thanks to Daniel Richard G.

Lasse Collin ac0b421265 Add missing include to tuklib_mbstr_width.c.
It didn't matter in XZ Utils because sysdefs.h
includes string.h anyway.

Lasse Collin de1f47b2b4 xz: Automatically align the strings in --info-memory.
This makes it easier to translate the strings.

Also, the string for amount of RAM was shortened.

Lasse Collin e873902641 Tests: Silence warnings from clang -Wassign-enum.
Also changed 999 to 99 so it fits even if lzma_check happened
to be 8 bits wide.

Lasse Collin a12b13c5f0 liblzma: Silence clang -Wmissing-variable-declarations. 2019-06-24 23:45:21 +03:00
Lasse Collin 1b4675cebf Add LZMA_RET_INTERNAL1..8 to lzma_ret and use one for LZMA_TIMED_OUT.
LZMA_TIMED_OUT is *internally* used as a value for lzma_ret
enumeration. Previously it was #defined to 32 and cast to lzma_ret.
That way it wasn't visible in the public API, but this was hackish.

Now the public API has eight LZMA_RET_INTERNALx members and
LZMA_TIMED_OUT is #defined to LZMA_RET_INTERNAL1. This way
the code is cleaner overall although the public API has a few
extra mysterious enum members.

Lasse Collin 2402f7873d xz: Fix an integer overflow with 32-bit off_t.
Or any off_t which isn't very big (like signed 64 bit integer
that most system have). A small off_t could overflow if the
file being decompressed had long enough run of zero bytes,
which would result in corrupt output.

Lasse Collin 4fd3a8dd0b xz: Cleanup io_seek_src() a bit.
lseek() returns -1 on error and checking for -1 is nicer.

Lasse Collin dfda7cf6af Tests: Remove a duplicate branch from tests/tests.h.
The duplication was introduced about eleven years ago and
should have been cleaned up back then already.

This was caught by -Wduplicated-branches.

Lasse Collin 1d4a904d8f xz: Change io_seek_src and io_pread arguments from off_t to uint64_t.
This helps fixing warnings from -Wsign-conversion and makes the
code look better too.

Lasse Collin dfac2c9a1d liblzma: Fix warnings from -Wsign-conversion.
Also, more parentheses were added to the literal_subcoder
macro in lzma_comon.h (better style but no functional change
in the current usage).

Lasse Collin 3ce05d235f tuklib_integer: Fix usage of conv macros.
Use a temporary variable instead of e.g.
conv32le(unaligned_read32ne(buf)) because the macro can
evaluate its argument multiple times.

Lasse Collin 33773c6f2a liblzma: Use unaligned_readXXne functions instead of type punning.
Now gcc -fsanitize=undefined should be clean.

Thanks to Jeffrey Walton.

Lasse Collin e5f13a6656 tuklib_integer: Autodetect support for unaligned access on ARM.
The result is used as the default for --enable-unaligned-access.
The test should work with GCC and Clang.

Lasse Collin 3bc112c2d3 tuklib_integer: Improve unaligned memory access.
Now memcpy() or GNU C packed structs for unaligned access instead
of type punning. See the comment in this commit for details.

Avoiding type punning with unaligned access is needed to
silence gcc -fsanitize=undefined.

New functions: unaliged_readXXne and unaligned_writeXXne where
XX is 16, 32, or 64.

Lasse Collin 2a22de439e liblzma: Avoid memcpy(NULL, foo, 0) because it is undefined behavior.
I should have always known this but I didn't. Here is an example
as a reminder to myself:

    int mycopy(void *dest, void *src, size_t n)
    {
        memcpy(dest, src, n);
        return dest == NULL;
    }

In the example, a compiler may assume that dest != NULL because
passing NULL to memcpy() would be undefined behavior. Testing
with GCC 8.2.1, mycopy(NULL, NULL, 0) returns 1 with -O0 and -O1.
With -O2 the return value is 0 because the compiler infers that
dest cannot be NULL because it was already used with memcpy()
and thus the test for NULL gets optimized out.

In liblzma, if a null-pointer was passed to memcpy(), there were
no checks for NULL *after* the memcpy() call, so I cautiously
suspect that it shouldn't have caused bad behavior in practice,
but it's hard to be sure, and the problematic cases had to be
fixed anyway.

Thanks to Jeffrey Walton.

Lasse Collin 4ed3396061 xz: In xz -lvv look at the widths of the check names too.
Now the widths of the check names is used to adjust the width
of the Check column. This way there no longer is a need to restrict
the widths of the check names to be at most ten terminal-columns.
