msys/python in MSYS2 pretends to be cygwin in all cases for some time
now, so this check was impossible to hit.
The underlying confusion it tried to prevent is still there, namely trying
to build with mingw but wrongly using a msys/cygwin python/meson.
We can use the MSYSTEM env var to detect if we are in a mingw shell, and
in case the Python doesn't match we suggest installing mingw variants of both
python and meson.
Using msys/python + meson in a MSYS environment works fine on the other hand,
so no need to error out in that case.
Fixes#8726
Also addresses the concern raised in
https://github.com/mesonbuild/meson/issues/3653#issuecomment-474122564
It isn't possible to have one target depend on a run_target, because
those produce no outputs and are always out of date. But the docs didn't
specify which types of target are valid here.
Correct the docs to align with the implementation.
Fixes#10198
They are RunTargets because they are one-shot commands without outputs.
But we implement them purely via our internal wrapper for gettext, so
there is no reason to wrap them *again* in our internal wrapper for
meson_exe and set a bunch of environment variables we know we absolutely
do not need, use, or want.
This avoids the ugly "wrapped due to env" status, and allows users to
directly see the command being run without going into despair at obscure
pickled nonsense.
It also offers a tiny defense against upgrading Meson without
reconfiguring. People should not do that, and we error out about this in
a bunch of places, but `--internal gettext` has a perfectly stable
interface just like most build tools that aren't part of Meson
internals, since it uses command line arguments instead of pickling.
Forcing serialization on when writing out the build rule makes very
little sense. It was always "forced" on because we mandated a couple of
environment variables due to legacy reasons.
Add an attribute to RunTarget to say that a given target doesn't *need*
those environment variables, and let ninja optimize them away and run
the command directly if set.
In commit 823da39909 we tried to fix
disappearing dependencies. Instead, we appended the replacement
dependencies to the existing ones. But this, too, was wrong. The
function doesn't return new dependencies... it returns a copied list
of all the dependencies, then alone of all parts of that API, expects to
overwrite the existing variable.
(Sadly, part of the internals actually uses the entire list for
something.)
As a result, we produced a repeatedly growing list, which eventually
scaled really badly and e.g. OOMed on gstreamer.
Instead, let's just replace the dependencies with the updated copy.
Tests the two new detection methods for the underscore prefix
against what is detected in the binary. Contrary to the in-the-wild
failures, we can trust the binary here as we do not get any additional
flags that influence the binary contents in this test environment.
When something goes wrong with running the compiler in
_symbols_have_underscore_prefix_searchbin, print stderr instead,
as it actually contains helpful output while stdout is usually empty
in this case.
Fixes the following ResourceWarnings:
ResourceWarning: subprocess 25556 is still running
_warn("subprocess %s is still running" % self.pid,
ResourceWarning: Enable tracemalloc to get the object allocation traceback
mesonbuild/compilers/mixins/gnu.py:195: ResourceWarning: unclosed file <_io.BufferedReader name=4>
return gnulike_default_include_dirs(tuple(self.exelist), self.language).copy()
ResourceWarning: Enable tracemalloc to get the object allocation traceback
Adds a new debug() function that can be used in the meson.build to
log messages to the meson-log.txt that will not be printed to stdout
when configuring the project.
Make use of pyinstaller hooks by creating a hook that updates how the
`mesonbuild` import functions.
This is more or less the same as passing a bajillion arguments to
pyinstaller's CLI, but allows the logic to be self-contained (and
reusable). It becomes more obvious what parts of the process pertain to
pyinstaller, and which parts pertain to MSI/pkg creation.
These are only used for type checking, so don't bother importing them at
runtime.
Generally add future annotations at the same time, to make sure that
existing uses of these imports don't need to be quoted.
That method had nothing specific to the backend, it's purely a Target
method. This allows to cache the OptionOverrideProxy object on the
Target instance instead of creating a new one for each option lookup.
argparse is the gift that keeps on giving, hahaha. Suppress the script
argument when --version is specified to avoid "required argument not
provided" errors, and print the python version.
The version argument is required in order to make this baseline
functional as a resolved python for find_program, which may specify a
version and expect this to work with python itself. Our incomplete CLI
wrapper over the python CLI interface was missing this.
Fixes#10162
In commit 68e684d51f the function
signature was changed, but several places did not adapt. Additionally,
we now totally dropped the in-place update of gtkdoc's sole source of
dependencies, but didn't propagate them upward to assign the newly
collected dependencies anywhere.
Fixes building gtkdoc with internal dependencies and failing when
specified directly (when building the 'all' target with sufficiently
random parallelism, deps may be built on time).

We currently inconsistently handle connection, `has_ssl`, and printing
errors on urlopen failure between `meson subprojects` and `meson wrap`.
Make the latter work more like the former.
We have a fallback route in `meson subprojects download` and friends,
which tries to retrieve wrapdb urls via http, if Python was not built
with SSL support.
Stop doing this. Replace it with a command line option to specify that
insecure downloads are wanted, and reference it in the error message if
downloading fails due to SSL issues.
Due to https://github.com/gcovr/gcovr/pull/576 it is not possible to
`pip install gcovr` and have it work.
It is possible, but not ideal, to install the cygwin gcovr package,
which is unmaintained and built for python36 while only depending on
python39.
This is of course not a problem on the other CI jobs, where we either
install it from a distro repository that ensures it is stable and
backports patches, or simply tests that the resulting image passes tests
before baking it as a CI images update.
gcovr upstream isn't sure when they are going to release a new version
that fixes this bug. There is a new feature release scheduled "soon".
In case a link is pointing_to an absolute path and we are using $DESTDIR
we fail in case the target is missing.
This is incorrect because we may need to use an absolute path to an
already installed file that is in $DESTDIR.
So if an absolute target is not existing, check if we have such file in
$DESTDIR before failing for real.
There is no need to go through all sources again, we already did that to
populate self.compilers. When cs or java compilers are in the list, then
there must be only one compiler.
The code was also not considering generate sources any way.
Previously subprojects inherited languages already added by main
project, or any previous subproject. This change to have a list of
compilers per interpreters, which means that if a subproject does not
add 'c' language it won't be able to compile .c files any more, even if
main project added the 'c' language.
This delays processing list of compilers until the interpreter adds the
BuildTarget into its list of targets. That way the interpreter can add
missing languages instead of duplicating that logic into BuildTarget for
the cython case.
Commit a0cade8f introduced a typo and wrongly check for
gtk4-update-icon-cache twice.
If gtk4-update-icon-cache (gtk4) is not found, look for
gtk-update-icon-cache (gtk3) instead.
