In the case the main project has a .wrap file for a cargo subproject,
that subproject's Cargo.lock must be loaded before we can recursively
fetch all its dependencies.
Introduce a global Cargo interpreter state that keeps track of enabled
features on each crate.
Before generating AST of a Cargo subproject, it downloads every
sub-subproject and resolves the set of features enabled on each of them
recursively. When it later generates AST for one its dependencies, its
set of features and dependencies is already determined.
When we're using the output of configure_file() with
override_find_program(), we weren't storing the version anywhere, so
get_version() was trying to run the script during setup.
This is usually fine, except in cases where the configure_file()
script actually has to import a library built as part of the project,
and fails to run.
For built executables, we simply use the project version, and we
now do the same here too.
Otherwise internal dependencies have auto-generated names that are not
human readable. Instead, use the name that the dependency overrides. For
example:
```meson
meson.override_dependency('zlib', declare_dependency())
dep_zlib = dependency('zlib')
assert(dep_zlib.name() == 'zlib')
```

If a user imports a module and invokes a method on it,
a raw Python exception is raised to the user. This commit
adds a check to ensure that in this case an appropriate
exception is raised instead.
A test has been added to ensure that this exception is
in fact raised on offending code.
Fixes: #11393, #5134
These errors can make reading comments and documentation
unnecessarily confusing for users and contributors who
do not speak English as their first language.
This commit harmonizes the handling of `d_import_dirs` and
`include_directories`. The treatment of `d_import_dirs` was also
different depending on the context: in `declare_dependency` it was
treated like the `include_directories`, but in `build_target` et al,
it had special treatment. With this commit, they are all treated
by the same function. The documentation has been updated to
reflect this.
Fixes#12742
When projects do not specify a minimum meson version, we used to avoid
giving them the benefit of the Feature checks framework. Instead:
- warn for features that were added after the most recent semver bump,
since they aren't portable to the range of versions people might use
these days
- warn for features that were deprecated before the upcoming semver
bump, i.e. all deprecated features, since they aren't portable to
upcoming semver-compatible versions people might be imminently upgrading
to
Although it's not especially common, there are certainly cases where it's
useful to pass the path to an external program to a test program.

Revert "interpreter: when overriding a dependency make its name match"
This reverts commit b1340e9bb1.
Revert "dependency: define equality and hash operators for Dependency"
This reverts commit 6d713e40f8.
This caused some projects to fail to build, such as libplacebo and
libepoxy. Taking libplacebo as the example, the produced build.ninja
does not include libvulkan.so as a linker input for
src/libplacebo.so.338.
We are probably getting dependency hashing wrong somewhere. Unsure where
exactly and unsure how to create a test case. We are also deep into rc2.
Revert it for now and try to re-land these changes for 1.6.
Bug: https://bugs.gentoo.org/935443Fixes: #13352
This reverts commit 9f02d0a3e5.
It turns out that this does introduce a behavioral change in existing
users of ConfigurationData, which it wasn't supposed to (it was supposed
to preserve behavior there, and add a new *warning* for
EnvironmentVariables).
This breaks projects such as pulseaudio, libvirt, and probably more.
Roll back the change and try again after 1.5.0 is released.
Fixes: #13372
When trying to get the version of a program, meson was previously
hardcoded to run the binary with `--version`. This does work with the
vast majority of programs, but there are a few outliers (e.g. ffmpeg)
which have an unusual argument for printing out the version. Support
these programs by introducing a version_argument kwarg in find_program
which allows users to override `--version` with whatever the custom
argument for printing the version may be for the program.
`configure_file` kwarg `copy` runs at configure time, whereas
`fs.copyfile` runs at build time. Both have use cases, so this
undeprecates the `configure_file` version.
Fixes: #12792
The docs didn't really explain what the issue was with using it. And
it's not actually a "crash" either way.
The FeatureNew mentions that "name" is new, but it is standard for
these warnings to tell you both the type of object you're operating on
and the name of the method that is an issue. This omitted the former,
and was very confusing.
Only Environment and ConfigurationData are mutable. However, only
ConfigurationData becomes immutable after first use which is
inconsistent.
This deprecates modification after first use of Environment object and
clarify documentation.
When a user writes `import'foo')`, Meson checks the
`mesonbuild/modules/` directory for a package called `foo.py`, and
attempts to import it. We don't want to expose any implementation detail
packages like `_qt.py`, so if someone write `import('_qt')`, we should
immediately give a "doesn't exist" error.
This incorrectly warns that `compiler.run()` is new in 1.5.0 for
Fortran, but that works fine for older versions (noted with 1.2.3). This
makes sense, as FortranCompiler inherits CLikeCompiler
This fixes issues where a new option is added, an option is removed, the
constraints of an option are changed, an option file is added where one
didn't previously exist, an option file is deleted, or it is renamed
between meson_options.txt and meson.options
There is one case that is known to not work, but it's probably a less
common case, which is setting options for an unconfigured subproject.
We could probably make that work in some cases, but I don't think it
makes sense to download a wrap during meson configure.
When we load the option file in the interpreter record which file it
was, and what the hash of that file was. This will let `meson configure`
know that the options have changed since the last re-configure.
