Jia Tan 14cd30806d liblzma: Improve documentation for container.h
Standardizing each function to always specify parameters and return
values. Also moved the parameters and return values to the end of each
function description.

Lasse Collin b9f171dd00 Update THANKS. 2023-02-17 20:56:49 +02:00
Lasse Collin 2ee86d20e4 Build: Use only the generic symbol versioning on MicroBlaze.
On MicroBlaze, GCC 12 is broken in sense that
__has_attribute(__symver__) returns true but it still doesn't
support the __symver__ attribute even though the platform is ELF
and symbol versioning is supported if using the traditional
__asm__(".symver ...") method. Avoiding the traditional method is
good because it breaks LTO (-flto) builds with GCC.

See also: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101766

For now the only extra symbols in liblzma_linux.map are the
compatibility symbols with the patch that spread from RHEL/CentOS 7.
These require the use of __symver__ attribute or __asm__(".symver ...")
in the C code. Compatibility with the patch from CentOS 7 doesn't
seem valuable on MicroBlaze so use liblzma_generic.map on MicroBlaze
instead. It doesn't require anything special in the C code and thus
no LTO issues either.

An alternative would be to detect support for __symver__
attribute in configure.ac and CMakeLists.txt and fall back
to __asm__(".symver ...") but then LTO would be silently broken
on MicroBlaze. It sounds likely that MicroBlaze is a special
case so let's treat it as a such because that is simpler. If
a similar issue exists on some other platform too then hopefully
someone will report it and this can be reconsidered.

(This doesn't do the same fix in CMakeLists.txt. Perhaps it should
but perhaps CMake build of liblzma doesn't matter much on MicroBlaze.
The problem breaks the build so it's easy to notice and can be fixed
later.)

Thanks to Vincent Fazio for reporting the problem and proposing
a patch (in the end that solution wasn't used):

Lasse Collin d831072cce liblzma: Very minor API doc tweaks.
Use "member" to refer to struct members as that's the term used
by the C standard.

Use lzma_options_delta.dist and such in docs so that in Doxygen's
HTML output they will link to the doc of the struct member.

Clean up a few trailing white spaces too.

Lasse Collin 718b22a6c5 liblzma: Silence a warning from MSVC.
It gives C4146 here since unary minus with unsigned integer
is still unsigned (which is the intention here). Doing it
with substraction makes it clearer and avoids the warning.

Thanks to Nathan Moinvaziri for reporting this.

Add \private above this field and its sub-fields since it is not meant
to be modified by users.

Jia Tan 0c9e4fc2ad liblzma: Fix documentation for LZMA_MEMLIMIT_ERROR.
LZMA_MEMLIMIT_ERROR was missing the "<" character needed to put
documentation after a member.

Lasse Collin 1dbe12b90c xz: Improve the comment about start_time in mytime.c.
start_time is relative to an arbitary point in time, it's not
time of day, so using it for anything else than time differences
wouldn't make sense.
2023-02-07 19:07:45 +02:00
Jia Tan 7673ef5aa8 Build: Adjust CMake version search regex.
Now, the LZMA_VERSION_MAJOR, LZMA_VERSION_MINOR, and LZMA_VERSION_PATCH
macros do not need to be on consecutive lines in version.h. They can be
separated by more whitespace, comments, or even other content, as long
as they appear in the proper order (major, minor, patch).

Jia Tan 2c78a83c6f liblzma: Fix bug in lzma_str_from_filters() not checking filters[] length.
The bug is only a problem in applications that do not properly terminate
the filters[] array with LZMA_VLI_UNKNOWN or have more than
LZMA_FILTERS_MAX filters. This bug does not affect xz.

Jia Tan 54ad83c1ae liblzma: Clarify block encoder and decoder documentation.
Added a few sentences to the description for lzma_block_encoder() and
lzma_block_decoder() to highlight that the Block Header must be coded
before calling these functions.
2023-02-03 00:22:53 +08:00

Jia Tan 1f7ab90d9c liblzma: Improve documentation for block.h.
Standardizing each function to always specify params and return values.
Output pointer parameters are also marked with doxygen style [out] to
make it clear. Any note sections were also moved above the parameter and
return sections for consistency.

Jia Tan c563a4bc55 liblzma: Clarify a comment about LZMA_STR_NO_VALIDATION.
The flag description for LZMA_STR_NO_VALIDATION was previously confusing
about the treatment for filters than cannot be used with .xz format
(lzma1) without using LZMA_STR_ALL_FILTERS. Now, it is clear that
LZMA_STR_NO_VALIDATION is not a super set of LZMA_STR_ALL_FILTERS.

Jia Tan 315c64c7e1 CI: Update .gitignore for artifacts directory in build-aux.
The workflow action for our CI pipeline can only reference artifacts in
the source directory, so we should ignore these files if the ci_build.sh
is run locally.

Lasse Collin 610dde15a8 xz: Use clock_gettime() even if CLOCK_MONOTONIC isn't available.
mythread.h and thus liblzma already does it.

Lasse Collin ff592c616e xz: Add SIGTSTP handler for progress indicator time keeping.
This way, if xz is stopped the elapsed time and estimated time
remaining won't get confused by the amount of time spent in
the stopped state.

This raises SIGSTOP. It's not clear to me if this is the correct way.
POSIX and glibc docs say that SIGTSTP shouldn't stop the process if
it is orphaned but this commit doesn't attempt to handle that.

Search for SIGTSTP in section 2.4.3:

Lasse Collin af5a4bd5af tuklib_physmem: Check for __has_warning before GCC version.
Clang can be configured to fake a too high GCC version so
this way it's more robust.

Jia Tan f35d98e206 liblzma: Fix documentation in filter.h for lzma_str_to_filters()
The previous documentation for lzma_str_to_filters() was technically
correct, but misleading. lzma_str_to_filters() returns NULL on success,
which is in practice always defined to 0. This is the same value as
LZMA_OK, but lzma_str_to_filters() does not return lzma_ret so we should
be more clear.

Lasse Collin 2f78ecc593 Revert "tuklib_common: Define __has_warning if it is not defined."
This reverts commit 82e3c968bf.

Macros in the reserved namespace (_foo or __foo) shouldn't be #defined
without a very good reason. Here the alternative would have been
to #define tuklib_has_warning(str) to an approriate value.

Also the tuklib_* files should stay namespace clean if possible.
2023-01-24 20:20:51 +08:00
Lasse Collin 8366cf8738 tuklib_physmem: Clean up the way -Wcast-function-type is silenced on Windows.
__has_warning and other __has_foo macros are meant to become
compiler-agnostic so it's not good to check for __clang__ with it.

This also relied on tuklib_common.h for #defining __has_warning
which was confusing as #defining reserved macros is generally
not a good idea.
