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.
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.
Standardizing each function to always specify parameters and return
values. Also moved the parameters and return values to the end of each
function description.
A few small things were reworded and long sentences broken up.
All functions now explicitly specify parameter and return values.
Also moved the note about SHA-256 functions not being exported to the
top of the file.
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).
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.
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.
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.
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.
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.
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:

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.
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.
__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.
A few Doxygen tags were obsolete from 1.4.7. Version 1.8.17 released
in 2019, so this should be compatible with resonable modern distros.
The purpose of Doxygen these days is for docs on the website, so it
doesn't necessarily have to work for everyone. Just when the maintainers
want to update the docs.
Doxygen is now configurable in autotools only with
--enable-doxygen=[api|all]. The default is "api", which will only
generate HTML output for liblzma API functions. The LaTex documentation
output was also disabled.
