Jia Tan 9ad64bdf30 tuklib_integer.h: Reverts previous commit.
Previous commit 6be460dde0 would cause an
error if the integer size was 32 bit.

Jia Tan 6be460dde0 tuklib_integer.h: Changes two other UINT_MAX == UINT32_MAX to >=. 2023-05-04 19:25:20 +08:00
Lasse Collin 44c0c5eae9 tuklib_integer.h: Fix a recent copypaste error in Clang detection.
Wrong line was changed in 7062348bf3.
Also, this has >= instead of == since ints larger than 32 bits would
work too even if not relevant in practice.

Jia Tan f41df2ac2f Windows: Include <intrin.h> when needed.
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.

Jia Tan 7062348bf3 tuklib_integer: Use __builtin_clz() with Clang.
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.

Jia Tan d0faa85df5 CI: Tests for disabling threading on CMake builds. 2023-03-29 23:46:43 +08:00
Jia Tan 8be5cc3b13 CI: Removes CMakeCache.txt between builds.
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.
2023-03-29 23:46:43 +08:00
Jia Tan 2cb6028fc3 CMake: Update liblzma-config.cmake generation.
Now that the threading is configurable, the liblzma CMake package only
needs the threading library when using POSIX threads.
2023-03-29 23:46:38 +08:00
Jia Tan 4d7fac0b07 CMake: Allows setting thread method.
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.

Jia Tan 20cd905d89 CI: Runs CMake feature tests.
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.
2023-03-24 23:41:06 +08:00
Jia Tan 4fabdb269f CI: ci_build.sh allows CMake features to be configured.
Also included various clean ups for style and helper functions for
repeated work.
2023-03-24 23:08:24 +08:00
Jia Tan cf3d1f130e CI: Change ci_build.sh to use bash instead of sh.
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.

Jia Tan ddfe164368 CMake: Only build xzdec if decoders are enabled. 2023-03-24 20:05:59 +08:00
Jia Tan 116e81f002 Build: Removes redundant check for LZMA1 filter support. 2023-03-23 21:48:52 +08:00
Lasse Collin 0ba234f692 CMake: Bump maximum policy version to 3.26.
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.
2023-03-23 21:48:52 +08:00
Jia Tan b0891684b4 CMake: Conditionally build xz list.* files if decoders are enabled. 2023-03-23 21:48:52 +08:00
Jia Tan 2c1a830efb CMake: Allow configuring features as cache variables.
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.

Lasse Collin 8be136f667 Build: Add a comment that AC_PROG_CC_C99 is needed for Autoconf 2.69.
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.
2023-03-21 14:07:51 +02:00
Lasse Collin 53cc475f26 Build: configure.ac: Use AS_IF and AS_CASE where required.
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 5a5bd7f871.

Lasse Collin 3b8890a402 Update THANKS. 2023-03-21 13:12:03 +02:00
Lasse Collin 5a5bd7f871 Build: Fix --disable-threads breaking the building of shared libs.
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 6629ed929c 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.

Jia Tan 509157c80c Doc: Rename Doxygen HTML doc directory name liblzma => api.
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.

Jia Tan fd90e2f4c2 liblzma: Remove note from lzma_options_bcj about the ARM64 exception.
This was left in by mistake since an early version of the ARM64 filter
used a different struct for its options.

Jia Tan 55ba6e9300 liblzma: Add set lzma.h as the main page for Doxygen documentation.
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.
