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
There are cases where we need to specify arguments to gtkdoc-mkdb, like
telling it to scan extensions that are not '.h' and '.c'. Let's add a
new named argument to gnome.gtkdoc(), as well as the plumbing needed for
the gtk-doc helper script.
Meson has a common pattern of using 'if len(foo) == 0:' or
'if len(foo) != 0:', however, this is a common anti-pattern in python.
Instead tests for emptiness/non-emptiness should be done with a simple
'if foo:' or 'if not foo:'
Consider the following:
>>> import timeit
>>> timeit.timeit('if len([]) == 0: pass')
0.10730923599840025
>>> timeit.timeit('if not []: pass')
0.030033907998586074
>>> timeit.timeit('if len(['a', 'b', 'c', 'd']) == 0: pass')
0.1154778649979562
>>> timeit.timeit("if not ['a', 'b', 'c', 'd']: pass")
0.08259823200205574
>>> timeit.timeit('if len("") == 0: pass')
0.089759664999292
>>> timeit.timeit('if not "": pass')
0.02340641999762738
>>> timeit.timeit('if len("foo") == 0: pass')
0.08848102600313723
>>> timeit.timeit('if not "foo": pass')
0.04032287199879647
And for the one additional case of 'if len(foo.strip()) == 0', which can
be replaced with 'if not foo.isspace()'
>>> timeit.timeit('if len(" ".strip()) == 0: pass')
0.15294511600222904
>>> timeit.timeit('if " ".isspace(): pass')
0.09413968399894657
>>> timeit.timeit('if len(" abc".strip()) == 0: pass')
0.2023209120015963
>>> timeit.timeit('if " abc".isspace(): pass')
0.09571301700270851
In other words, it's always a win to not use len(), when you don't
actually want to check the length.
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.
'gtkdoc-scangobj' script was recently ported to Python (it was Perl), and it now requires providing '--type' option to specify the name of the file to store the types in. Without this option, 'gtkdockelper' will exit with error status 2 and will throw a message "gtkdoc-scangobj: error: unrecognized arguments: <typefile>"
'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.
Points to the `mesonintrospect.py` script corresponding to the
currently-running version of Meson.
Includes a test for all three methods of running scripts/commands.
Closes https://github.com/mesonbuild/meson/issues/1385
With the 'install_mode' kwarg, you can now specify the file and
directory permissions and the owner and the group to be used while
installing. You can pass either:
* A single string specifying just the permissions
* A list of strings with:
- The first argument a string of permissions
- The second argument a string specifying the owner or
an int specifying the uid
- The third argument a string specifying the group or
an int specifying the gid
Specifying `false` as any of the arguments skips setting that one.
The format of the permissions kwarg is the same as the symbolic
notation used by ls -l with the first character that specifies 'd',
'-', 'c', etc for the file type omitted since that is always obvious
from the context.
Includes unit tests for the same. Sadly these only run on Linux right
now, but we want them to run on all platforms. We do set the mode in the
integration tests for all platforms but we don't check if they were
actually set correctly.
