2023-04-25CI: ci_build.sh allows configuring small build.Jia Tan1-1/+6
2023-04-20Update THANKS.Jia Tan1-0/+1
2023-04-19Windows: Include <intrin.h> when needed.Jia Tan2-0/+16
Legacy Windows did not need to #include <intrin.h> to use the MSVC intrinsics. Newer versions likely just issue a warning, but the MSVC documentation says to include the header file for the intrinsics we use. GCC and Clang can "pretend" to be MSVC on Windows, so extra checks are needed in tuklib_integer.h to only include <intrin.h> when it will is actually needed.
2023-04-19tuklib_integer: Use __builtin_clz() with Clang.Jia Tan1-3/+3
Clang has support for __builtin_clz(), but previously Clang would fallback to either the MSVC intrinsic or the regular C code. This was discovered due to a bug where a new version of Clang required the <intrin.h> header file in order to use the MSVC intrinsics. Thanks to Anton Kochkov for notifying us about the bug.
2023-04-14liblzma: Update project maintainers in lzma.h.Lasse Collin1-1/+1
AUTHORS was updated earlier, lzma.h was simply forgotten.

2023-03-29CI: Tests for disabling threading on CMake builds.Jia Tan2-5/+2
2023-03-29CI: Removes CMakeCache.txt between builds.Jia Tan1-0/+2
If the cache file is not removed, CMake will not reset configurations back to their default values. In order to make the tests independent, it is simplest to purge the cache. Unfortunatly, this will slow down the tests a little and repeat some checks.
2023-03-29CMake: Update liblzma-config.cmake generation.Jia Tan1-11/+22
Now that the threading is configurable, the liblzma CMake package only needs the threading library when using POSIX threads.
2023-03-29CMake: Allows setting thread method.Jia Tan1-40/+104
The thread method is now configurable for the CMake build. It matches the Autotools build by allowing ON (pick the best threading method), OFF (no threading), posix, win95, and vista. If both Windows and posix threading are both available, then ON will choose Windows threading. Windows threading will also not use: target_link_libraries(liblzma Threads::Threads) since on systems like MinGW-w64 it would link the posix threads without purpose.
2023-03-24CI: Runs CMake feature tests.Jia Tan1-114/+55
Now, CMake will run similar feature disable tests that the Autotools version did before. In order to do this without repeating lines in ci.yml, it now makes sense to use the GitHub Workflow matrix to create a loop.
2023-03-24CI: ci_build.sh allows CMake features to be configured.Jia Tan1-90/+143
Also included various clean ups for style and helper functions for repeated work.
2023-03-24CI: Change ci_build.sh to use bash instead of sh.Jia Tan1-1/+1
This script is only meant to be run as part of the CI build/test process on machines that are known to have bash (Ubuntu and MacOS). If this assumption changes in the future, then the bash specific commands will need to be replaced with a more portable option. For now, it is convenient to use bash commands.
2023-03-24CMake: Only build xzdec if decoders are enabled.Jia Tan1-1/+1
2023-03-23Build: Removes redundant check for LZMA1 filter support.Jia Tan1-4/+1
2023-03-23CMake: Bump maximum policy version to 3.26.Lasse Collin1-1/+1
It adds only one new policy related to FOLDERS which we don't use. This makes it clear that the code is compatible with the policies up to 3.26.
2023-03-23CMake: Conditionally build xz list.* files if decoders are enabled.Jia Tan1-2/+7
2023-03-23CMake: Allow configuring features as cache variables.Jia Tan1-137/+391
This allows users to change the features they build either in CMakeCache.txt or by using a CMake GUI. The sources built for liblzma are affected by this too, so only the necessary files will be compiled.
2023-03-21Build: Add a comment that AC_PROG_CC_C99 is needed for Autoconf 2.69.Lasse Collin1-0/+3
It's obsolete in Autoconf >= 2.70 and just an alias for AC_PROG_CC but Autoconf 2.69 requires AC_PROG_CC_C99 to get a C99 compiler.
2023-03-21Build: configure.ac: Use AS_IF and AS_CASE where required.Lasse Collin1-15/+15
This makes no functional difference in the generated configure (at least with the Autotools versions I have installed) but this change might prevent future bugs like the one that was just fixed in the commit 5a5bd7f871818029d5ccbe189f087f591258c294.
2023-03-21Update THANKS.Lasse Collin1-0/+1
2023-03-21Build: Fix --disable-threads breaking the building of shared libs.Lasse Collin1-8/+8
This is broken in the releases 5.2.6 to 5.4.2. A workaround for these releases is to pass EGREP='grep -E' as an argument to configure in addition to --disable-threads. The problem appeared when m4/ax_pthread.m4 was updated in the commit 6629ed929cc7d45a11e385f357ab58ec15e7e4ad which introduced the use of AC_EGREP_CPP. AC_EGREP_CPP calls AC_REQUIRE([AC_PROG_EGREP]) to set the shell variable EGREP but this was only executed if POSIX threads were enabled. Libtool code also has AC_REQUIRE([AC_PROG_EGREP]) but Autoconf omits it as AC_PROG_EGREP has already been required earlier. Thus, if not using POSIX threads, the shell variable EGREP would be undefined in the Libtool code in configure. ax_pthread.m4 is fine. The bug was in configure.ac which called AX_PTHREAD conditionally in an incorrect way. Using AS_CASE ensures that all AC_REQUIREs get always run. Thanks to Frank Busse for reporting the bug. Fixes: https://github.com/tukaani-project/xz/issues/45
2023-03-19liblzma: Silence -Wsign-conversion in SSE2 code in memcmplen.h.Lasse Collin1-1/+2

These should have been included in 5.3.2alpha already.
2023-03-17CMake: Add microlzma_*.c to the build.Lasse Collin1-0/+2
These should have been included in 5.3.2alpha already.
2023-03-17Build: Update comments about unaligned access to mention 64-bit.Lasse Collin2-6/+5
2023-03-17Tests: Update .gitignore.Lasse Collin1-1/+2
2023-03-17po4a/update-po: Display the script name consistently in error messages.Lasse Collin1-1/+1
2023-03-17Doc: Rename Doxygen HTML doc directory name liblzma => api.Jia Tan5-22/+22
When the docs are installed, calling the directory "liblzma" is confusing since multiple other files in the doc directory are for liblzma. This should also make it more natural for distros when they package the documentation.
2023-03-17liblzma: Remove note from lzma_options_bcj about the ARM64 exception.Jia Tan1-1/+1
This was left in by mistake since an early version of the ARM64 filter used a different struct for its options.
2023-03-17CI: Add doxygen as a dependency.Jia Tan1-3/+2
Autogen now requires --no-doxygen or having doxygen installed to run without errors.
2023-03-17COPYING: Add a note about the included Doxygen-generated HTML.Lasse Collin1-0/+11
2023-03-17Doc: Update PACKAGERS with details about liblzma API docs install.Jia Tan1-6/+16
2023-03-17liblzma: Add set lzma.h as the main page for Doxygen documentation.Jia Tan15-29/+2
The \mainpage command is used in the first block of comments in lzma.h. This changes the previously nearly empty index.html to use the first comment block in lzma.h for its contents. lzma.h is no longer documented separately, but this is for the better since lzma.h only defined a few macros that users do not need to use. The individual API header files all have a disclaimer that they should not be #included directly, so there should be no confusion on the fact that lzma.h should be the only header used by applications. Additionally, the note "See ../lzma.h for information about liblzma as a whole." was removed since lzma.h is now the main page of the generated HTML and does not have its own page anymore. So it would be confusing in the HTML version and was only a "nice to have" when browsing the source files.
2023-03-17Build: Generate doxygen documentation in autogen.sh.Jia Tan1-6/+29
Another command line option (--no-doxygen) was added to disable creating the doxygen documenation in cases where it not wanted or if the doxygen tool is not installed.
2023-03-17Build: Create doxygen/update-doxygen script.Jia Tan2-0/+112
This is a helper script to generate the Doxygen documentation. It can be run in 'liblzma' or 'internal' mode by setting the first argument. It will default to 'liblzma' mode and only generate documentation for the liblzma API header files. The helper script will be run during the custom mydist hook when we create releases. This hook already alters the source directory, so its fine to do it here too. This way, we can include the Doxygen generated files in the distrubtion and when installing. In 'liblzma' mode, the JavaScript is stripped from the .html files and the .js files are removed. This avoids license hassle from jQuery and other libraries that Doxygen 1.9.6 puts into jquery.js in minified form.
2023-03-17Build: Install Doxygen docs and include in distribution if generated.Jia Tan1-0/+18
Added a install-data-local target to install the Doxygen documentation only when it has been generated. In order to correctly remove the docs, a corresponding uninstall-local target was added. If the doxygen docs exist in the source tree, they will also be included in the distribution now too.
2023-03-17Doxygen: Refactor Doxyfile.in to doxygen/Doxyfile.Lasse Collin4-309/+456
Instead of having Doxyfile.in configured by Autoconf, the Doxyfile can have the tags that need to be configured piped into the doxygen command through stdin with the overrides after Doxyfile's contents. Going forward, the documentation should be generated in two different modes: liblzma or internal. liblzma is useful for most users. It is the documentation for just the liblzma API header files. This is the default. internal is for people who want to understand how xz and liblzma work. It might be useful for people who want to contribute to the project.
2023-03-13Tests: Remove unused macros and functions.Jia Tan1-75/+0
2023-03-13liblzma: Defines masks for return values from lzma_index_checks().Jia Tan2-11/+34
2023-03-13Tests: Refactors existing lzma_index tests.Jia Tan1-544/+1492
Converts the existing lzma_index tests into tuktests and covers every API function from index.h except for lzma_file_info_decoder, which can be tested in the future.
2023-03-11xz: Simplify the error-label in Capsicum sandbox code.Lasse Collin1-15/+12
Also remove unneeded "sandbox_allowed = false;" as this code will never be run more than once (making it work with multiple input files isn't trivial).
2023-03-08xz: Make Capsicum sandbox more strict with stdin and stdout.Lasse Collin1-0/+8
2023-03-08Revert: "Add warning if Capsicum sandbox system calls are unsupported."Jia Tan1-6/+4
The warning causes the exit status to be 2, so this will cause problems for many scripted use cases for xz. The sandbox usage is already very limited already, so silently disabling this allows it to be more usable.
2023-03-07xz: Fix -Wunused-label in io_sandbox_enter().Jia Tan1-2/+2
Thanks to Xin Li for recommending the fix.
2023-03-06xz: Add warning if Capsicum sandbox system calls are unsupported.Jia Tan1-0/+2
The warning is only used when errno == ENOSYS. Otherwise, xz still issues a fatal error.
2023-03-06xz: Skip Capsicum sandbox system calls when they are unsupported.Jia Tan1-5/+17
If a system has the Capsicum header files but does not actually implement the system calls, then this would render xz unusable. Instead, we can check if errno == ENOSYS and not issue a fatal error.
2023-03-06xz: Reorder cap_enter() to beginning of capsicum sandbox code.Jia Tan1-3/+3
cap_enter() puts the process into the sandbox. If later calls to cap_rights_limit() fail, then the process can still have some extra protections.
2023-03-01liblzma: Clarify lzma_lzma_preset() documentation in lzma12.h.Jia Tan1-0/+5
lzma_lzma_preset() does not guarentee that the lzma_options_lzma are usable in an encoder even if it returns false (success). If liblzma is built with default configurations, then the options will always be usable. However if the match finders hc3, hc4, or bt4 are disabled, then the options may not be usable depending on the preset level requested. The documentation was updated to reflect this complexity, since this behavior was unclear before.
2023-02-27CMake: Require that the C compiler supports C99 or a newer standard.Lasse Collin1-0/+8
Thanks to autoantwort for reporting the issue and suggesting a different patch: https://github.com/tukaani-project/xz/pull/42
2023-02-24Tests: Small tweak to test-vli.c.Jia Tan1-0/+2
The static global variables can be disabled if encoders and decoders are not built. If they are not disabled and -Werror is used, it will cause an usused warning as an error.
2023-02-24liblzma: Replace '\n' -> newline in filter.h documentation.Jia Tan1-1/+1
The '\n' renders as a newline when the comments are converted to html by Doxygen.
2023-02-24liblzma: Shorten return description for two functions in filter.h.Jia Tan1-6/+2
Shorten the description for lzma_raw_encoder_memusage() and lzma_raw_decoder_memusage().
2023-02-24liblzma: Reword a few lines in filter.hJia Tan1-5/+5
2023-02-24liblzma: Improve documentation in filter.h.Jia Tan1-83/+143
All functions now explicitly specify parameter and return values. The notes and code annotations were moved before the parameter and return value descriptions for consistency. Also, the description above lzma_filter_encoder_is_supported() about not being able to list available filters was removed since lzma_str_list_filters() will do this.
2023-02-23Update THANKS.Lasse Collin1-0/+1
2023-02-23liblzma: Avoid null pointer + 0 (undefined behavior in C).Lasse Collin10-23/+77
In the C99 and C17 standards, section 6.5.6 paragraph 8 means that adding 0 to a null pointer is undefined behavior. As of writing, "clang -fsanitize=undefined" (Clang 15) diagnoses this. However, I'm not aware of any compiler that would take advantage of this when optimizing (Clang 15 included). It's good to avoid this anyway since compilers might some day infer that pointer arithmetic implies that the pointer is not NULL. That is, the following foo() would then unconditionally return 0, even for foo(NULL, 0): void bar(char *a, char *b); int foo(char *a, size_t n) { bar(a, a + n); return a == NULL; } In contrast to C, C++ explicitly allows null pointer + 0. So if the above is compiled as C++ then there is no undefined behavior in the foo(NULL, 0) call. To me it seems that changing the C standard would be the sane thing to do (just add one sentence) as it would ensure that a huge amount of old code won't break in the future. Based on web searches it seems that a large number of codebases (where null pointer + 0 occurs) are being fixed instead to be future-proof in case compilers will some day optimize based on it (like making the above foo(NULL, 0) return 0) which in the worst case will cause security bugs. Some projects don't plan to change it. For example, gnulib and thus many GNU tools currently require that null pointer + 0 is defined: https://lists.gnu.org/archive/html/bug-gnulib/2021-11/msg00000.html https://www.gnu.org/software/gnulib/manual/html_node/Other-portability-assumptions.html In XZ Utils null pointer + 0 issue should be fixed after this commit. This adds a few if-statements and thus branches to avoid null pointer + 0. These check for size > 0 instead of ptr != NULL because this way bugs where size > 0 && ptr == NULL will likely get caught quickly. None of them are in hot spots so it shouldn't matter for performance. A little less readable version would be replacing ptr + offset with offset != 0 ? ptr + offset : ptr or creating a macro for it: #define my_ptr_add(ptr, offset) \ ((offset) != 0 ? ((ptr) + (offset)) : (ptr)) Checking for offset != 0 instead of ptr != NULL allows GCC >= 8.1, Clang >= 7, and Clang-based ICX to optimize it to the very same code as ptr + offset. That is, it won't create a branch. So for hot code this could be a good solution to avoid null pointer + 0. Unfortunately other compilers like ICC 2021 or MSVC 19.33 (VS2022) will create a branch from my_ptr_add(). Thanks to Marcin Kowalczyk for reporting the problem: https://github.com/tukaani-project/xz/issues/36

2023-02-17Update THANKS.Lasse Collin1-0/+1
2023-02-17Build: Use only the generic symbol versioning on MicroBlaze.Lasse Collin1-2/+10
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): https://github.com/tukaani-project/xz/pull/32
2023-02-16liblzma: Very minor API doc tweaks.Lasse Collin4-14/+14
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.
2023-02-17liblzma: Adjust spacing in doc headers in bcj.h.Jia Tan1-7/+7

Also adjusted preset value => preset level.
2023-02-16liblzma: Silence a warning from MSVC.Lasse Collin1-1/+1
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.
2023-02-16 liblzma: Improve documentation for stream_flags.hJia Tan1-30/+46
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.
2023-02-15liblzma: Improve documentation in lzma12.h.Jia Tan1-9/+23
All functions now explicitly specify parameter and return values.
2023-02-15liblzma: Improve documentation in check.h.Jia Tan1-13/+28

2023-02-15liblzma: Omit lzma_index_iter's internal field from Doxygen docs.Jia Tan1-1/+8
Add \private above this field and its sub-fields since it is not meant to be modified by users.
2023-02-14liblzma: Fix documentation for LZMA_MEMLIMIT_ERROR.Jia Tan1-1/+1
LZMA_MEMLIMIT_ERROR was missing the "<" character needed to put documentation after a member.
2023-02-14liblzma: Improve documentation for base.h.Jia Tan1-5/+25
Standardizing each function to always specify params and return values. Also fixed a small grammar mistake.
2023-02-14liblzma: Add one more missing [out] annotation in vli.hJia Tan1-1/+1
2023-02-14liblzma: Minor improvements to vli.h.Jia Tan1-6/+7
Added [out] annotations to parameters that are pointers and can have their value changed. Also added a clarification to lzma_vli_is_valid.
2023-02-10liblzma: Add comments for macros in delta.h.Jia Tan1-0/+8
Document LZMA_DELTA_DIST_MIN and LZMA_DELTA_DIST_MAX for completeness and to avoid Doxygen warnings.
2023-02-10liblzma: Improve documentation in index_hash.h.Jia Tan1-9/+27
All functions now explicitly specify parameter and return values. Also reworded the description of lzma_index_hash_init() for readability.
2023-02-07xz: Improve the comment about start_time in mytime.c.Lasse Collin1-5/+10
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.
2023-02-04Build: Adjust CMake version search regex.Jia Tan1-0/+2
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).
2023-02-04xz: Add a comment clarifying the use of start_time in mytime.c.Jia Tan1-0/+5
2023-02-04liblzma: Improve documentation for version.h.Jia Tan1-7/+22
Specified parameter and return values for API functions and documented a few more of the macros.
2023-02-03Docs: Omit SIGTSTP not handled from TODO.Jia Tan1-4/+0
2023-02-03liblzma: Fix bug in lzma_str_from_filters() not checking filters[] length.Jia Tan1-0/+7
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.
2023-02-03Tests: Create test_filter_str.c.Jia Tan3-0/+596
Tests lzma_str_to_filters(), lzma_str_from_filters(), and lzma_str_list_filters() API functions.

2023-02-03liblzma: Clarify block encoder and decoder documentation.Jia Tan1-4/+11
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.

2023-02-03liblzma: Clarify comment in block.h.Jia Tan1-1/+2
2023-02-03liblzma: Improve documentation for block.h.Jia Tan1-21/+75
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.
2023-02-01liblzma: Clarify a comment about LZMA_STR_NO_VALIDATION.Jia Tan1-2/+3
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.
2023-02-01CI: Update .gitignore for artifacts directory in build-aux.Jia Tan1-0/+1
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.
2023-02-01CI: Add quotes around variables in a few places.Jia Tan1-3/+3

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.

2023-01-24liblzma: Fix documentation in filter.h for lzma_str_to_filters()Jia Tan1-1/+1
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.
2023-01-24Revert "tuklib_common: Define __has_warning if it is not defined."Lasse Collin1-7/+0
This reverts commit 82e3c968bfa10e3ff13333bd9cbbadb5988d6766. 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.
2023-01-24tuklib_physmem: Clean up the way -Wcast-function-type is silenced on Windows.Lasse Collin1-4/+13
__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.
2023-01-20Doxygen: Make Doxygen only produce liblzma API documentation by default.Jia Tan2-9/+48
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.

2023-01-19tuklib_physmem: Silence warning from -Wcast-function-type on MinGW-w64.Jia Tan1-0/+9
tuklib_physmem depends on GetProcAddress() for both MSVC and MinGW-w64 to retrieve a function address. The proper way to do this is to cast the return value to the type of function pointer retrieved. Unfortunately, this causes a cast-function-type warning, so the best solution is to simply ignore the warning.
2023-01-19tuklib_common: Define __has_warning if it is not defined.Jia Tan1-0/+7
clang supports the __has_warning macro to determine if the version of clang compiling the code supports a given warning. If we do not define it for other compilers, it may cause a preprocessor error.
2023-01-18CI: Reorder 32-bit build first for Linux autotool builds.Jia Tan1-5/+12
The 32-bit build needs to be first so the configure cache only needs to be reset one time. The 32-bit build sets the CFLAGS env variable, so any build using that flag after will fail unless the cache is reset.

Disabling shared library generation and linking should help speed up the runners. The shared library is still being tested in the 32 bit build and the full feature. Disabling nls is to check for any unexpected warnings or errors.

It doesn't warn on a 64-bit system because truncating a ptrdiff_t (signed long) to uint32_t is diagnosed under -Wconversion by GCC and -Wshorten-64-to-32 by Clang.

-Wstrict-aliasing was removed from the list since it is enabled by -Wall already. A normal build is clean with these on GNU/Linux x86-64 with GCC 12.2.0 and Clang 14.0.6.
2023-01-12Tests: Fix warnings from clang --Wassign-enum.Lasse Collin4-8/+17
Explicitly casting the integer to lzma_check silences the warning. Since such an invalid value is needed in multiple tests, a constant INVALID_LZMA_CHECK_ID was added to tests.h. The use of 0x1000 for lzma_block.check wasn't optimal as if the underlying type is a char then 0x1000 will be truncated to 0. However, in these test cases the value is ignored, thus even with such truncation the test would have passed.
2023-01-12Tests: Silence warnings from -Wsign-conversion.Lasse Collin2-8/+8
Note that assigning an unsigned int to lzma_check doesn't warn on GNU/Linux x86-64 since the enum type is unsigned on that platform. The enum can be signed on some other platform though so it's best to use enumeration type lzma_check in these situations.
2023-01-12liblzma: Silence warnings from clang -Wconditional-uninitialized.Lasse Collin2-4/+6
This is similar to 2ce4f36f179a81d0c6e182a409f363df759d1ad0. The actual initialization of the variables is done inside mythread_sync() macro. Clang doesn't seem to see that the initialization code inside the macro is always executed.

2023-01-10liblzma: CLMUL CRC64: Work around a bug in MSVC, second attempt.Lasse Collin1-0/+18
This affects only 32-bit x86 builds. x86-64 is OK as is. I still cannot easily test this myself. The reporter has tested this and it passes the tests included in the CMake build and performance is good: raw CRC64 is 2-3 times faster than the C version of the slice-by-four method. (Note that liblzma doesn't include a MSVC-compatible version of the 32-bit x86 assembly code for the slice-by-four method.) Thanks to Iouri Kharon for figuring out a fix, testing, and benchmarking.

2023-01-10sysdefs.h: Don't include strings.h anymore.Lasse Collin1-6/+0
On some platforms src/xz/suffix.c may need <strings.h> for strcasecmp() but suffix.c includes the header when it needs it. Unless there is an old system that otherwise supports enough C99 to build XZ Utils but doesn't have C89/C90-compatible <string.h>, there should be no need to include <strings.h> in sysdefs.h.
2023-01-10xz: Include <strings.h> in suffix.c if needed for strcasecmp().Lasse Collin1-0/+3
SUSv2 and POSIX.1‐2017 declare only a few functions in <strings.h>. Of these, strcasecmp() is used on some platforms in suffix.c. Nothing else in the project needs <strings.h> (at least if building on a modern system). sysdefs.h currently includes <strings.h> if HAVE_STRINGS_H is defined and suffix.c relied on this. Note that dos/config.h doesn't #define HAVE_STRINGS_H even though DJGPP does have strings.h. It isn't needed with DJGPP as strcasecmp() is also in <string.h> in DJGPP.

2023-01-10sysdefs.h: Don't include memory.h anymore even if it were available.Lasse Collin1-6/+2
It quite probably was never needed, that is, any system where memory.h was required likely couldn't compile XZ Utils for other reasons anyway. XZ Utils 5.2.6 and later source packages were generated using Autoconf 2.71 which no longer defines HAVE_MEMORY_H. So the code being removed is no longer used anyway.

At least on some systems, GNU windres needs --use-temp-file in addition to the \x20 hack to avoid spaces in the command line argument. Hovever, that \x20 syntax is broken with llvm-windres version 15.0.0 (results in "XZx20Utils") but luckily it works with a regular space. Thus it is best to limit the workarounds to GNU toolchain on Windows.
2023-01-09Tests: test_filter_flags: Clean up minor issues.Lasse Collin1-75/+78
Here are the list of the most significant issues addressed: - Avoid using internal common.h header. It's not good to copy the constants like this but common.h cannot be included for use outside of liblzma. This is the quickest thing to do that could be fixed later. - Omit the INIT_FILTER macro. Initialization should be done with just regular designated initializers. - Use start_offset = 257 for BCJ tests. It demonstrates that Filter Flags encoder and decoder don't validate the options thoroughly. 257 is valid only for the x86 filter. This is a bit silly but not a significant problem in practice because the encoder and decoder initialization functions will catch bad alignment still. Perhaps this should be fixed but it's not urgent and doesn't need to be in 5.4.x. - Various tweaks to comments such as filter id -> Filter ID
