Test that add_project_dependencies() can only be used before build targets
have been declared. Also test that one cannot use override_dependency
on a superproject to inject a superproject's build products into the
subproject. This would violate the rule that build products cannot be used
with add_project_dependencies() (similar to e.g. compiler.has_function),
so check that meson detects the situation correctly.
This allows tracking which subproject it came from at the time of
definition, rather than the time of use. As a result, it is no longer
possible for one subproject which knows that another subproject installs
some data files, to expose those data files via its own
declare_dependency.
There are somewhat common, reasonable and legitimate use cases for a
dependency to provide data files installed to /usr which are used as
command inputs. When getting a dependency from a subproject, however,
the attempt to directly construct an input file from a subproject
results in a sandbox violation. This means not all dependencies can be
wrapped as a subproject.
One example is wayland-protocols XML files which get scanned and used to
produce C source files.
Teach Meson to recognize when a string path is the result of fetching a
dep.get_variable(), and special case this to be exempt from subproject
violations.
A requirement of this is that the file must be installed by
install_data() or install_subdir() because otherwise it is not actually
representative of what a pkg-config dependency would provide.
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.
This bring us in line with Autotools and CMake and it is useful
for platforms like Nix, which install projects
into multiple independent prefixes.
As a consequence, `get_option` might return absolute paths for some
directory options, if a directory outside of prefix is passed.
This is technically a backwards incompatible change but its effect
should be minimal, thanks to widespread use of `join_paths`/`/` operator
and pkg-config generator module. It should only cause an issue when
a path were constructed by concatenating the value of directory path option.
Also remove a comment about commonpath since we do not use that since
<00f5dadd5b>.

Because we don't want to pass the Interpreter kwargs into the build
layer. This turned out to be a mega commit, as there's really on elegant
way to make this change in an incremental way. On the nice side, mypy
made this change super easy, as nearly all of the calls to
`CustomTarget` are fully type checked!
It also turns out that we're not handling install_tags in custom_target
correctly, since we're not converting the boolean values into Optional
values!
Fixes a bug where the subproject version was not validated
when the subproject had already been processed.
The bug would cause inconsistent build results if the subproject was
referenced more than once (diamond) with conflicting version requirements.
Emit a detailed deprecation warning that explains what to do instead.
Also add a unittest.
```
DEPRECATION: target prog links against shared module mymod, which is incorrect.
This will be an error in the future, so please use shared_library() for mymod instead.
If shared_module() was used for mymod because it has references to undefined symbols,
use shared_libary() with `override_options: ['b_lundef=false']` instead.
```
Fixes https://github.com/mesonbuild/meson/issues/9492
Make the handling of bindgen inputs consistent with the inputs and outputs of
source_strings_to_files.
However, for the first source argument reject anything that cannot
possibly be an header file. This also fixes a mypy failure from the next
patch, since ExtractedObjects does not have a zero-argument get_outputs
method.

Currently, if you pass a `[]string`, but the argument expects
`[]number`, then you get a message like `expected list[str] but got
list`. That isn't helpful. With this patch arrays and dictionaries will
both print messages with the types provided.
Without this patch, the name of the RunTarget is passed to the
install script; for the enclosed test, meson setup (incorrectly)
succeeds, but installation fails.
Fixes the following error in the testcase:

This is the final refactoring for extracting the bultin object
logic out of Interpreterbase. I decided to do both arrays and
dicts in one go since splitting it would have been a lot more
confusing.
Another commit in my quest to rid InterpreterBase from all higher
level object processing logic.
Additionally, there is a a logic change here, since `str.join` now
uses varargs and can now accept more than one argument (and supports
list flattening).
Explicitly mention that the project definition is invalid, and clarify
that project is `project()` -- a function.
Also try to walk the directory tree upward, and if there are parent
meson.build files, just say this isn't the project root, and "maybe you
meant to run meson there instead?"
This won't catch calls to subdir('foo/bar') but we can't be perfect,
only better than before and catch the *majority* of such cases, and
hopefully it's a lot more clear if meson protests that the project is
"invalid, there is no project() function", where the user should look
for a potential solution.
Fixes#3426
This is useful both from the perspective of optional functionality that
requires a module, and also as I continue to progress with Meson++,
which will probably not implement all of the modules that Meson itself
does.
The dependency lookup is a lot of complex code. This refactor it all
into a single file/class outside of interpreter main class. This new
design allows adding more fallbacks candidates in the future (e.g. using
cc.find_library()) but does not yet add any extra API.
Add a method to perform a logical AND on a feature object. The method
also takes care of raising an error if 'enabled' is ANDed with false.
