Remove the code responsible for implicitly compressing manpages as .gz
files. It has been established that manpage compression is a distro
packager's task, with existing distros already having their own
implementations of compression.
Fixes#4330
This has the adventage that "meson --help" shows a list of all commands,
making them discoverable. This also reduce the manual parsing of
arguments to the strict minimum needed for backward compatibility.
Since we're supposed to call this for each installed path, we only should go
through what we've installed and not what this point to, as it might be
outside our scope or not existent.
To do this, since shutil.chown doesn't expose the follow_symlink that os.chown
has, we can temporarily replace os.chown with a lambda that acutually passes
all the values as we want them, and then restore it to the built-in functions.
Not the nicest way, but fixes the issue without having to reimplement what
shutil does.
Fixes#3914
It's only supported by few platforms when the linked file exists, while it
would cause an error otherwise.
In any case just implement this via an helper set_chmod function that will
handle the case where follow_symlinks is not supported by the platform
and will just not set any mod for the link itself (as it would otherwise
apply to the linked file).
Fixes#3914
Shared modules may be resource-only DLLs, or might automatically
self-initialize using C constructors or WinMain at DLL load time.
When an import library is not found for a shared module, just print
a message about it instead of erroring out.
Fixes#3965
This was added accidentally. Includes a test for it.
Also fix a rebase error. The variable was defined incorrectly and was
overwritten with the correct value immediately afterwards.
On macOS, we set the install_name for built libraries to
@rpath/libfoo.dylib, and when linking to the library, we set the RPATH
to its path in the build directory. This allows all built binaries to
be run as-is from the build directory (uninstalled).
However, on install, we have to strip all the RPATHs because they
point to the build directory, and we change the install_name of all
built libraries to the absolute path to the library. This causes the
install name in binaries to be out of date.
We now change that install name to point to the absolute path to each
built library after installation.

With this, the default workflow on macOS matches what everyone seems
to do, including Autotools and CMake. The next step is providing a way
for build files to override the install_name that is used after
installation for use with, f.ex., private libraries when combined with
the install_rpath: kwarg on targets.
The install name is used by consumers of the library to find the
library at runtime. If it's @rpath/libfoo.dylib, all consumers must
manually add the library path to RPATH, which is not what people
expect.
Almost everyone sets the library install name as the full path to the
library, and this is done at install time with install_name_tool.
This makes it possible to customize permissions of all installable
targets, such as executable(), libraries, man pages, header files and
custom or generated targets.
This is useful, for instance, to install setuid/setgid binaries, which
was hard to accomplish without access to this attribute.
This option controls the permissions of installed files (except for
those specified explicitly using install_mode option, e.g. in
install_data rules.)
An install-umask of 022 will install all binaries, directories and
executable files with mode rwxr-xr-x, while all data and non-executable
files will be installed with mode rw-r--r--.
Setting install-umask to the string 'preserve' will disable this
feature, keeping the permissions of installed files same as the files in
the build tree (or source tree for install_data and install_subdir.)
Note that, in this case, the umask used when building and that used when
checking out the source tree will leak into the install tree.
Keep the default as 'preserve', to show that no behavior is changed and
all tests keep passing unchanged.
Tested: ./run_tests.py
Print full destination path in 'Installing subdir ...' message,
including DESTDIR, consistent with other installation functions.
Use separate dst_dir and full_dst_dir variables to avoid mixing up
the order in the future and make code more readable.
Closes#3006.
- Pass exclude_files and exclude_directories relative to src_dir,
same as specified by user and documented in public install_subdir().
- Make do_copydir() interface similar to do_copyfile():
install src_dir contents to dst_dir.
- Remove src_prefix/src_dir code, it adds confusion and duplicates arguments.
Use single src_dir parameter instead.
- Make callers specify that src_dir contents should be installed
under dst_dir/basename(src_dir) if necessary.
- Use os.path.relpath() instead of string manipulations on paths.
- Add documentation to do_copydir(): specify types and add usage example.
According to Python documentation[1] dirname and basename
are defined as follows:
os.path.dirname() = os.path.split()[0]
os.path.basename() = os.path.split()[1]
For the purpose of better readability split() is replaced
by appropriate function if only one part of returned tuple
is used.

This avoids hundres of warnings like:
Warning no default label for /var/tmp/instroot.hUbtYJ/path/to/some/binary
$DESTDIR is usually set to a temporary path, in which case the path is
unknown to selinux. For that case we could just skip the restorecon
calls. But sometimes it is used with a path to container. In that
case, most of the time, selinux has no context for that path. But we
can't rule that out somebody added custom context rules for the
container. So let's still call restorecon, but silence the warning.
Introduce a DirMaker class that disassembles the path up to '/' and stores all
directories in a list. That list is in creation order and pre-existing
directories are ignored, i.e. creating the two paths
'/usr/share/foo/bar/baz' and '/usr/share/foo/bar/boo' is stored as
[ '/usr/share/foo',
'/usr/share/foo/bar',
'/usr/share/foo/bar/baz',
'/usr/share/foo/bar/boo' ]
This is on the assumption that /usr/share already existed.
After all files have been installed, the list of created directories is
appended in reverse order to the install log. The uninstall script then
triggers rmdir on all directories.
If a custom install script drops files into the directories, removing those
will fail. This matches the current expectation, see the existing warning
"Remember that files created by custom scripts have not been removed."
Unfortunately, this makes the behavior on uninstall inconsistent. Assuming a
non-existing prefix,
ninja install && ninja uninstall
removes all traces of the install.
However,
ninja install && ninja install && ninja uninstall
removes the files only, not the directories as they already existed.
This could be fixed by just unconditionally removing any (emtpy) directories
that we drop files into, at the risk of removing system directories if empty.
For example, one could imagine /etc/foo.conf.d/ to be removed in that case if
it is empty.

Try to restore the context for SELinux. If we fail on running
'selinuxenabled', quietly ignore the error and continue. If we fail on the
actual restorecon call, we print a message but disable SELinux - chances are
high that if one restorecon fails, others will too and that's likely a system
setup issue.
Fixes#1967
Grammatically, this full stop isn't needed and with file names it has a
potential to be confusing:
Installing /foo/bar/filename.1 to /foo/bar/dirname.
The full stop caused me to do a double-take more than once, so let's drop it.
'test cases/common/12 data' and 'test cases/common/66 install subdir' both
try to install something as 'root'. This user doesn't exist on Cygwin.
Perhaps we should automatically convert this to some other user, but it's
not clear which. For real projects, it's possibly better for the meson.build
to explicitly handle this...
'test cases/common/12 data' also tries to install something with GID 0.
There's no guarantee this group exists.
