Lasse Collin b0d1422b60 CMake: Don't assume that -fvisibility=hidden is supported outside Windows.
The original code was good enough for supporting GNU/Linux
and a few others but it wasn't very portable.

CMake doesn't support Solaris Studio's -xldscope=hidden.
If it ever does, things should still work with this commit
as Solaris Studio supports not only its own __global but also
the GNU C __attribute__((visibility("default"))). Support for the
attribute was added in 2007 to Sun Studio 12 compiler version 5.9.

Lasse Collin 4430e075f7 CMake: Use -O2 instead of -O3 in CMAKE_BUILD_TYPE=Release.
-O3 doesn't seem useful for speed but it makes the code bigger.
CMake makes is difficult for users to simply override the
optimization level: CFLAGS / CMAKE_C_FLAGS aren't helpful because
they go before CMAKE_C_FLAGS_RELEASE. Of course, users can override
CMAKE_C_FLAGS_RELEASE directly but then they have to remember to
add also -DNDEBUG to disable assertions.

This commit changes -O3 to -O2 in CMAKE_C_FLAGS_RELEASE if and only if
CMAKE_C_FLAGS_RELEASE cache variable doesn't already exist. So if
a custom value is passed on the command line (or reconfiguring an
already-configured build), the cache variable won't be modified.

Lasse Collin 74e8bc7417 CMake: Add test_scripts.sh to the tests.
In contrast to Automake, skipping of this test when decoders
are disabled is handled at CMake side instead of test_scripts.sh
because CMake-build doesn't create config.h.

Lasse Collin 4808f238a7 CMake: Install scripts.
Compared to the Autotools-based build, this has simpler handling
for the shell (@POSIX_SHELL@) and extra PATH entry for the scripts
(configure has --enable-path-for-scripts=PREFIX). The simpler
metho should be enough for non-ancient systems and Solaris.

Lasse Collin 3462362ebd Scripts: Use @PACKAGE_VERSION@ instead of @VERSION@.
PACKAGE_VERSION was already used in liblzma.pc.in.
This way only one version @foo@ is used.

Lasse Collin 67610c245b CMake: Simplify symlink creation and install translated man pages.
It helps that cmake_install.cmake doesn't parallelize installation
so symlinks can be created so that the target is always known to
exist (a requirement on Windows in some cases).

This bumps the minimum CMake version from 3.13 to 3.14 to use
file(CREATE_LINK ...). It could be made to work on 3.13 by
calling "cmake -E create_symlink" but it's uglier code and
slower in "make install". 3.14 should be a reasonable version
to require nowadays, especially since the Autotools build
is still the primary build system for most OSes.

Lasse Collin 50cc1d8a5a CMake: Add support for building and installing xz with translations.
If gettext tools are available, the .po files listed in po/LINGUAS
are converted using msgfmt. This allows building with translations
directly from xz.git without Autotools.

If gettext tools aren't available, the Autotools-created .gmo files
in the "po" directory will be used. This allows CMake-based build
to use translations from Autotools-generated tarball.

If translation support is found (Intl_FOUND) but both the
gettext tools and the pre-generated .gmo files are missing,
then "make" will fail.

Lasse Collin cae9a5e0bf xz: Use stricter pledge(2) and Landlock sandbox.
This makes these sandboxing methods stricter when no files are
created or deleted. That is, it's a middle ground between the
initial sandbox and the strictest single-file-to-stdout sandbox:
this allows opening files for reading but output has to go to stdout.

Lasse Collin 02e3505991 xz: Support Landlock ABI version 4.
Linux 6.7 added support for ABI version 4 which restricts
TCP connections which xz won't need and thus those can be
forbidden now. Since the ABI version is handled at runtime,
supporting version 4 won't cause any compatibility issues.

Note that new enough kernel headers are required to get
version 4 support enabled at build time.
2024-02-17 23:07:35 +02:00
Lasse Collin 374868d81d xz: Move sandboxing code to sandbox.c and improve Landlock sandbox.
Landlock is now always used just like pledge(2) is: first in more
permissive mode and later (under certain common conditions) in
a strict mode that doesn't allow opening more files.

I put pledge(2) first in sandbox.c because it's the simplest API
to use and still somewhat fine-grained for basic applications.
So it's the simplest thing to understand for anyone reading sandbox.c.

Lasse Collin c701a5909a xz: Fix message_init() description.
Also explicitly initialize progress_automatic to make it clear
that it can be read before message_init() sets it. Static variable
was initialized to false by default already so this is only for
clarity.

Lasse Collin f1d6b88aef liblzma: Avoid implementation-defined behavior in the RISC-V filter.
GCC docs promise that it works and a few other compilers do
too. Clang/LLVM is documented source code only but unsurprisingly
it behaves the same as others on x86-64 at least. But the
certainly-portable way is good enough here so use that.

Sebastian Andrzej Siewior e9053c9072 liblzma/rangecoder: Exclude x32 from the x86-64 optimisation.
The x32 port has a x86-64 ABI in term of all registers but uses only
32bit pointer like x86-32. The assembly optimisation fails to compile on
x32. Given the state of x32 I suggest to exclude it from the
optimisation rather than trying to fix it.
