Since it's also used in the rust module, it should be in a common place.
Also rename from `TEST_KWARGS` to `TEST_KWS`, which is more in line with
the `*_KW` naming scheme used in the type_checking module.
Which adds the `use-set-for-membership` check. It's generally faster in
python to use a set with the `in` keyword, because it's a hash check
instead of a linear walk, this is especially true with strings, where
it's actually O(n^2), one loop over the container, and an inner loop of
the strings (as string comparison works by checking that `a[n] == b[n]`,
in a loop).
Also, I'm tired of complaining about this in reviews, let the tools do
it for me :)
This finds uses of deny-listed functions, which defaults to map and
filter. These functions should be replaced by comprehensions in
idiomatic python because:
1. comprehensions are more heavily optimized and are often faster
2. They avoid the need for lambdas in some cases, which make them
faster
3. you can do the equivalent in one statement rather than two, which
is faster
4. They're easier to read
5. if you need a concrete instance (ie, a list) then you don't have
to convert the iterator to a list afterwards
The `py.dependency(embed: false)` method is supposed to consistently
provide a distutils-like `python.pc` / `python-embed.pc` interface
regardless of Python version. It handles both pkg-config and sysconfig
scraping. For the latter, we respect the value of self.link_libpython
as determined by distutils, and construct a fully custom dependency. For
the former, we blindly assume pkg-config is correct.
It isn't correct, not until Python 3.8 when embed was added. Before
then, we need to process the pkg-config dependency based on
link_libpython. We did this, but only inside the extension_module
method, which is obviously wrong.
Delete the special casing from extension_module, and handle it inside
the dependency.
Fixes#11097
On Windows, in Python version prior to 3.8.7, the `sysconfig` modules
provides an extension filename suffix that disagrees the one returned
by `distutils.sysconfig`. Get the more awesome suffix from the latter
when building for a Python version known to present this issue.
Simplify the extension module filename suffix lookup to use the same
method used by `setuptools`.
Adjust project tests accordingly.
Fixes#10960.
Since commit 32b14b1bb5, hotdoc is run
during configure as an external program. It turns out though, that in
some cases we passed NoneType in the cmd array, previously to
hotdoc.run_hotdoc.run() and now via subprocesses. The former "worked"
due to ignoring unknown arguments (?) but the latter was broken because
command line interfaces don't accept python NoneType objects, naturally.
End result: when for example building Meson's own documentation, this
fails with a python traceback.
The reason this happens to begin with turns out to be, once again,
because of the legacy debt of homebrewed kwargs parsing. We have a
function for `process_known_args` that handles args and ignores them if
they are NoneType, and then include_paths is handled via a custom
processor that internally adds them, then returns a *list* of NoneType
which then gets appended to the global cmd, because the logic ends up as
`[None, None] is None` which is a failed check, so we go ahead and add
it.
It's odd that we ever attempted to process it twice to begin with, so
let's simply not do that.
We are just using this dictionary to get keys, and we could also just
set it ourselves but with None values. But we have a code abstraction
for this already; use it.
We need to run it as an external command at build time anyway, and we
detect it by looking it up as an ExternalProgram. It seems odd to then
import it into Meson's python interpreter and run the main function.
Moreover, this errors out when you are running two different pythons,
one for Meson and one for hotdoc. For example, when hotdoc is installed
normally, but you're testing Meson against a nondefault newer version of
python.
We consistently use the "dependencies" kwarg to refer to C-like
CFLAGS/LDFLAGS interfaces. And for hotdoc, we actually accept libraries
for this as well, as we may want to document their (generated?) sources,
so we want their CFLAGS too.
But we also accepted custom targets and just added a build order
dependency on these, which was odd and typically we call that "depends".
Let's deprecate this in favor of the depends kwarg.
Internally we pass this as extra_depends to the CustomTarget
initializer, so it makes sense to call it that rather than confusing the
topic by referring to "dependencies", a term that indicates
CFLAGS/LDFLAGS interfaces.
GeneratedLists as sources to `gnome.gdbus_codegen` worked until
version 0.60 of Meson, but broke in 0.61 because of the conversion to
typed_pos_args and typed_kwargs. Reinstate this by adding them to the
decorators and annotations.
Note that gdbus_codegen desugars to two custom_targets and therefore the
generator is invoked twice. This is not optimal, but it should not be
an issue and can be changed later.

While generators also used to work, they are a bit tricky because
gdbus_codegen desugars to two custom_targets and therefore the generator
is invoked twice. This should not be a problem, but be explicit and
leave that to a separate commit to highlight the problem.

We accept a list of known kwargs of required types, but also arbitrary
kwargs understood by the hotdoc program (sometimes via extensions). Now
that we can partially type-check kwargs, do so here.
This catches some optimization problems, mostly in the use of `all()`
and `any()`. Basically writing `any([x == 5 for x in f])` vs `any(x == 5
for x in f)` reduces the performance because the entire concrete list
must first be created, then iterated over, while in the second f is
iterated and checked element by element.
itstool detects a language code from the mo file’s basename,
so when 26c1869a14
changed the file name to be prefixed with project name,
values like “my-project-xx” ended up in the `xml:lang` attribute
of the generated page files, instead of the expected
IETF BCP 47 language tag.
Let’s fix it by passing a locale code to itstool explicitly.
This removes the need for the use of the global statement. I've also
updated the test that overrides this to use mock.patch instead of hand
monkey patching.
It turns out we don't generally need to proxy every compiler ever
through the top-level package. The number of times we directly poke at
one is negligible and direct imports are pretty clean.
Gettext should search for input files relative to the (sub)project
source root, not the global source root.
This change exposes a root_subdir member in ModuleState.
wayland-scanner can generate header files that only include
wayland-client-core.h using a flag.
Add a core_only option to scan_xml to support this use case.
Strictly speaking code restructuring isn't needed, but making this PEP8
compliant results in indentation of the code that reduces the
readability. By moving the offending code on the outside of the method
call, the readability is maintained.
Generally plumb through the values of get_option() passed to
install_dir, and use this to establish the install plan name. Fixes
several odd cases, such as:
- {datadir} being prepended to "share" or "include"
- dissociating custom install directories and writing them out as
{prefix}/share/foo or {prefix}/lib/python3.10/site-packages
This is the second half of #9478Fixes#10601
The name can be None if a library is not passed as a positional
argument, and the name keyword argument is not provided. We shouldn't
allow that to happen.
