Cargo sometimes adds new keys and Meson needs to gracefully handle
those. Currently, an unknown key will trigger an uncaught Python
exception, which is pretty much the worse case. With this change Meson
will instead issue a warning much like the one for unknown cpu
architectures.
See #13826 for the motivation for this change
The library name defaults to its package name, but it can be different.
For example:
- package name: cairo-sys-rs
- library name: cairo-sys
- dependency name: ffi
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.
The first versions of Emscripten that correspond with the Clang version
Meson uses to determine flag support don't actually support the expected
flags. So I went through and picked the first version that actually
worked with the expected flags.
Fixes#13628
Both recvmmsg/sendmmsg and statx require the `_GNU_SOURCE` symbol to be
defined to be shown in headers, but statx has the additional property of
being defined on all glibc systems[1], unlike recvmmsg which isn't
implemented on Hurd[2][3].
With this fix, all tests now pass on Hurd.

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')
```

The x86 test files might not work on x86_64 Linux in certain cases,
for example if the kernel is configured without support for x86
executables (which also gets rid of the old system call interface).

It is genuinely horribly buggy so we don't want the testsuite to
succeed. We make a special exception for the CI runner since it is a
known breakage but people packaging meson should see the issue.
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
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
The zlib symbols may not be of type 'T' but rather e.g. 'D' -- instead,
tell nm to emit the POSIX format and also to only emit defined symbols,
not undefined ones. Then we just check if the symbol is listed at all,
regardless of type.
We already depend on -U elsewhere (e.g symbolextractor). There's no real
replacement for it, sadly. It's also buggy in some versions of nm, so we
check both its long and short options.

If kwargs_force_multiline is enabled, an ArgumentNode in a kwarg value can
already be marked multiline by the time we notice that the line needs to
be broken for length. Ensure we still break the line in this case.

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.

The following is valid meson:
```meson
a = '''This string can't be simplified'''
```
which cannot be simplified because of the `'` in it, as
```meson
a = 'This string can't be simplified'
```
Is invalid.
Potentially we could convert that with escapes, but it seems reasonable
to me to leave this, since it may be desirable to not have lots of
escapes in a string. `'''I can't believe it's her's!'''` is much more
readable than `'I can\'t believe it\'s her\'s!'`, for example.

- Fix indentation of comments in arrays
- Fix indentation of comments in dicts
- Fix indentation of comments in if clauses
- Fix indentation of comments in foreach clauses
Which happens when a .editorconfig is in a subdirectory, not the root.
In this case we need Set the fallback value to `False`, which is what
editorconfig expects.

The pkgconfig file in Debian and Ubuntu is definitely broken and we've
reported it upstream, but we don't really want to keep our image building
failing while we wait for that to be fixed.
Skip the auto/pkgconfig test if both: a) we're on Ubuntu, and b) the .pc
checksum matches a known-bad copy. I'm also CC'd to the bug to catch if it
gets fixed.
Bug: https://bugs.debian.org/1078026
Test '230 external project' uses make, but is too dumb to use the
platform conventions for shared library names in installed files
expected by shared_lib, so special case that.
By default, we build with debug info which can be useful for
investigating why a test segfaults instead of either passing or failing.
The nasm language hooks this up, but using nasm as a generator program
does not.

For other reasons, Meson transforms "-Wno-x" into "-Wx -Wno-x" for GCC,
but this breaks with "-Wno-attributes=x" with:
```
cc1plus: error: arguments ignored for '-Wattributes='; use '-Wno-attributes=' instead
```
Suppress that workaround for -Wno-attributes=.

aee941559 ("rust: recursively pull proc-macro dependencies as well")
had to be reverted (in a66cb97e8) because it broke Mesa cross
compilation. This happened because a C shared library was linked with
a Rust C-ABI static library, which caused it to inherit the proc macro
dependency the Rust static library was linked with.
The right way to handle this is for only Rust targets to inherit proc
macro dependencies from static libraries they link with. A Rust
executable, library, or whatever will need the proc macros its Rust
dependencies use, as illustrated in the test case that I've
reintroduced here.
I've verified that Mesa still cross compiles correctly with this
change. The same failure was also identified by the "rust/21
transitive dependencies" test case, but only when cross compiling, so
it wasn't caught by CI.

We have two ways of marking a test as skipped:
- raise MESON_SKIP_TEST
- declare that the tools it needs in test.json are unavailable
Doing the former requires performing the configure stage including e.g.
language setup.
In several cases we weren't even getting this far anyway since we used
both mechanisms (the cmake category has a category-wide skip for this,
in fact). In some case, we were missing test.json declaring it skippable;
add this.
This tests that CMake link flags marked as PRIVATE are not propagated
through the generated Meson dependency. -Wl,--version-script is used as
the "poison" here, the build ultimately fails if it appears in the
shared_library() link command.
