2023-08-02build-aux/manconv.sh: Fix US-ASCII and UTF-8 output.Lasse Collin1-2/+2
groff defaults to SGR escapes. Using -P-c passes -c to grotty which restores the old behavior. Perhaps there is a better way to get pure plain text output but this works for now.

2023-08-01mythread.h: Disable signal functions in builds targeting Wasm + WASI.ChanTsune1-1/+1
signal.h in WASI SDK doesn't currently provide sigprocmask() or sigset_t. liblzma doesn't need them so this change makes liblzma and xzdec build against WASI SDK. xz doesn't build yet and the tests don't either as tuktest needs setjmp() which isn't (yet?) implemented in WASI SDK. Closes: https://github.com/tukaani-project/xz/pull/57 See also: https://github.com/tukaani-project/xz/pull/56 (The original commit was edited a little by Lasse Collin.)

2023-08-01CMake: Conditionally allow the creation of broken symlinks.Jia Tan1-7/+75
The CMake build will try to create broken symlinks on Unix and Unix-like platforms. Cygwin and MSYS2 are Unix-like, but may not be able to create broken symlinks. The value of the CYGWIN or MSYS environment variables determine if broken symlinks are valid. The default for MSYS2 does not allow for broken symlinks, so the CMake build has been broken for MSYS2 since commit 80a1a8bb838842a2be343bd88ad1462c21c5e2c9.
2023-08-01liblzma: Prevent an empty translation unit in Windows builds.Jia Tan1-1/+5
To workaround Automake lacking Windows resource compiler support, an empty source file is compiled to overwrite the resource files for static library builds. Translation units without an external declaration are not allowed by the C standard and result in a warning when used with -Wempty-translation-unit (Clang) or -pedantic (GCC).

Previously if the lzip decoder was not configured then test_files.sh would pass the lzip tests instead of skipping them.

2023-07-18liblzma: Improve comment in string_conversion.c.Jia Tan1-2/+2
The comment used "flag" when referring to decoder options. Just referring to them as options is more clear and consistent.
2023-07-18liblzma: Reword lzma_str_list_filters() documentation.Jia Tan1-1/+1
Reword "options required" to "options read". The previous wording may have suggested that the options listed were all required when the filters are used for encoding or decoding. Now it should be more clear that the options listed are the ones relevant for encoding or decoding.
2023-07-18xz: Translate the second "%s: " in message.c since French needs "%s : ".Lasse Collin1-1/+1

2023-07-18liblzma: Prevent warning for MSYS2 Windows build.Jia Tan1-2/+4
In lzma_memcmplen(), the <intrin.h> header file is only included if _MSC_VER and _M_X64 are both defined but _BitScanForward64() was previously used if _M_X64 was defined. GCC for MSYS2 defines _M_X64 but not _MSC_VER so _BitScanForward64() was used without including <intrin.h>. Now, lzma_memcmplen() will use __builtin_ctzll() for MSYS2 GCC builds as expected.
2023-07-18Docs: Add a new section to INSTALL for Tests.Jia Tan1-17/+64
The new Tests section describes basic information about the tests, how to run them, and important details when cross compiling. We have had a few questions about how to compile the tests without running them, so hopefully this information will help others with the same question in the future. Fixes: https://github.com/tukaani-project/xz/issues/54

2023-07-18xz: Fix typo in man page.Jia Tan1-1/+1
The Memory limit information section described three output columns when it actually has six. This was reworded to "multiple" to make it more future proof.
2023-07-18Tests: Improve feature testing for skipping.Jia Tan2-3/+3
Fixed a bug where test_compress_* would all fail if arm64 or armthumb filters were enabled for compression but arm was disabled. Since the grep tests only checked for "define HAVE_ENCODER_ARM", this would match on HAVE_ENCODER_ARM64 or HAVE_ENCODER_ARMTHUMB. Now the config.h feature test requires " 1" at the end to prevent the prefix problem. have_feature() was also updated for this even though there were known current bugs affecting it. This is just in case future features have a similar prefix problem.

2023-07-18Tests: Fix memory leaks in test_block_header.Jia Tan1-16/+22
test_block_header was not properly freeing the filter options between calls to lzma_block_header_decode(). The memory leaks were discovered by using -fsanitize=address with GCC.
2023-07-18liblzma: Prevent uninitialzed warning in mt stream encoder.Jia Tan1-1/+1
This change only impacts the compiler warning since it was impossible for the wait_abs struct in stream_encode_mt() to be used before it was initialized since mythread_condtime_set() will always be called before mythread_cond_timedwait(). Since the mythread.h code is different between the POSIX and Windows versions, this warning was only present on Windows builds. Thanks to Arthur S for reporting the warning and providing an initial patch.

2023-07-18CMake: Protects against double find_packageBenjamin Buch1-7/+9
Boost iostream uses `find_package` in quiet mode and then again uses `find_package` with required. This second call triggers a `add_library cannot create imported target "LibLZMA::LibLZMA" because another target with the same name already exists.` This can simply be fixed by skipping the alias part on secondary `find_package` runs.

Wrong line was changed in 7062348bf35c1e4cbfee00ad9fffb4a21aa6eff7. Also, this has >= instead of == since ints larger than 32 bits would work too even if not relevant in practice.

2023-04-25Windows: 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.
2023-04-25tuklib_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.

2023-04-25CMake: 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.
2023-04-25CMake: 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.

2023-03-21Build: 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.

2023-03-17Doc: Rename Doxygen HTML doc directory name liblzma => api.Jia Tan5-22/+22

2023-03-17liblzma: Remove note from lzma_options_bcj about the ARM64 exception.Jia Tan1-1/+1

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.Jia Tan5-1237/+2686
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.

2023-03-11xz: Make Capsicum sandbox more strict with stdin and stdout.Lasse Collin1-0/+8
2023-03-11xz: Don't fail if Capsicum is enabled but kernel doesn't support it.Lasse Collin1-3/+12
(This commit combines related commits from the master branch.) If Capsicum support is missing from the kernel or xz is being run in an emulator that lacks Capsicum suport, the syscalls will fail and set errno to ENOSYS. Previously xz would display and error and exit, making xz unusable. Now it will check for ENOSYS and run without sandbox support. Other tools like ssh behave similarly. Displaying a warning for missing Capsicum support was considered but such extra output would quickly become annoying. It would also break test_scripts.sh in "make check". Also move cap_enter() to be the first step instead of the last one. This matches the example in the cap_rights_limit(2) man page. With the current code it shouldn't make any practical difference though. Thanks to Xin Li for the bug report, suggesting a fix, and testing: https://github.com/tukaani-project/xz/pull/43 Thanks to Jia Tan for most of the original commits.
2023-03-07Build: 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).

2023-03-07liblzma: 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.

2023-03-07liblzma: 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.

2023-03-07liblzma: 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().

2023-03-07Build: 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

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 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.

2023-02-03tuklib_physmem: Silence warning from -Wcast-function-type on MinGW-w64.Jia Tan1-0/+18
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.

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.
2023-02-03Tests: 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.
2023-02-03Tests: 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.

2023-01-11sysdefs.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.
2023-01-11xz: 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.

2023-01-11liblzma: 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.

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.

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
