It was generating #include with the basename of every header file. That
assumes that every directory where there are headers are also included
into search path when compiling the .c file.
Change to use path relative to current subdir, which can be both in
build or source directory. That means that we assume that when the .c
file is compiled, the target has a include_directories pointing to the
directory where gnome.mkenum_simple() has been called, which is
generally '.' and added automatically.
Also fix type annotation to only allow str and File sources, other types
have never been working, it would require to iterate over custom target
outputs, etc.
Fixes: #7582
We already import a bunch of objects directly from ..build but don't use
them nearly as much as we can. This resulted both in longer lines and s
minor performance difference since python has to resolve the name
binding the long way. There's no reason not to rewrite these names to
use the direct imports.
Found while investigating the fact that Executable was imported but
never used. It's easier to just use it.
This detects cases where module A imports a function from B, and C
imports that same function from A instead of B. It's not part of the API
contract of A, and causes innocent refactoring to break things.
This reverts commit a2def550c5.
This results in a 2k line file being unconditionally imported at
startup, and transitively loading two more (for a total cost of 2759
lines of code), and it's not clear it was ever needed to begin with...
This lessens the amount of code imported at Meson startup by mapping
each dependency to a dictionary entry and using a programmable import to
dynamically return it.
Minus 16 files and 6399 lines of code imported at startup.
We may want to do things like update install scripts as well, which have
to happen before generating the backend. Instead of adding one module
method per thing to do, use a single function that allows for modifying
the Build object directly.
Mainly thi sis that `state.find_program()` is annotated incorrectly, it
returns `ExternalProgram | Executable | OverrideProgram`, but it's
annotated to return only `ExteranlProgram`, and thus a bunch of the
annotations in the gnome module are wrong.
It's probably not useful to spam the user with warnings that old
versions of software may not behave correctly when the first warning was
perfectly valid.
There are lots of warnings that become fatal, that are simply unfixable
by the end user. Things like using old versions of software (because
they're using some kind of LTS release), warnings about compilers not
supporting certain kinds of checks, or standards being upgraded due to
skipped implementations (MSVC has c++98 and c++14, but not c++11). None
of these should be fatal, they're informative, and too important to
reduce to notices, but not important enough to stop meson if they're
printed.
T.Sequence is a questionable concept. The idea is to hammer out generic,
maximally forgiving APIs that operate on protocols, which is a fancy way
of saying "I don't care if you use tuples or lists". This is rarely
needed, actually, and in exchange for this fancy behavior you get free
bugs.
Specifically, `somestr` is of type `T.Sequence[str]`, and also
`somestr[0]` is another string of type you guessed it. It's ~~turtles~~
strings all the way down.
It's worth noting that trying to code for "protocols" is a broken
concept if the contents have semantic meaning, e.g. it operates on
"the install tags of this object" rather than "an iterable that supports
efficient element access".
The other way to use T.Sequence is "I don't like that T.List is
invariant, but also I don't like that T.Tuple makes you specify exact
ordering". This sort of works. In fact it probably does work as long as
you don't allow str in your sequences, which of course everyone allows
anyway.
Use of Sequence has cute side effects, such as actually passing lists
around, knowing that you are going to get a list and knowing that you
need to pass it on as a list, and then having to re-allocate as
`list(mylist)` "because the type annotations says it could be a str or
tuple".
Except it cannot be a str, because if it is then the application is
fatally flawed and logic errors occur to disastrous end user effects,
and the type annotations:
- do not enforce their promises of annotating types
- fail to live up to "minimal runtime penalties" due to all the `list()`
Shun this broken concept, by hardening the type annotations. As it turns
out, we do not actually need any of this covariance or protocol-ism for
a list of strings! The whole attempt was a slow, buggy waste of time.
It is only used by Environment.get_exe_wrapper() and every callers were
handling None already. Type annotation was wrong, it already could
return None for the case an exe wrapper is needed but none is provided.
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 :)
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.

Custom targets as sources to `gnome.gdbus_codegen` worked until version 0.60

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.

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.
Instead of using FeatureNew/FeatureDeprecated in the module.
The goal here is to be able to handle information about modules in a
single place, instead of having to handle it separately. Each module
simply defines some metadata, and then the interpreter handles the rest.
This removes one line of stderr output per GObject Introspection file
processed, e.g.
g-ir-scanner: link: gcc -o Fwupd-2.0 Fwupd-2.0.o -L. -Wl,-rpath...
In commit 3dcc712583 we moved to
typed_pos_args. In the process, we deleted some code to specifically
raise an error if you use custom_target or generator outputs, instead
leaving it out of the typed pos args.
However, that support was specifically supposed to be there. It was only
an error in part of an if statement for handling old versions of
glib-compile-resources. The specific error it calls out is that we need
to manually parse the depfile at configure time, due to an external bug;
obviously this is impossible if the gresource is only created at build
time.
Reinstate the original error message check, and allow built outputs to
be used as compile_resources() inputs.
Fixes#10367
Just like some of glib tools, wayland-scanner can be defined in the
pkgconfig dependency variables. Share code between gnome and wayland
modules into ModuleState.
We need to setup the environment we pass to g-ir-scanner because it will
try to use pkg-config to find dependencies, and that must respect user
settings from machine file. Also make it use uninstalled pc files Meson
generated in the case dependencies, such as glib, have been built as
subproject.
This moves generally useful logic from GNOME module's
_get_native_binary() into find_program() implementation. We could decide
later to expose it as public API.
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.
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.
