This is a follow-up to gh-8706, which contained the initial fix
to ninjabackend.py but somehow lost it. This re-applies the fix
and adds a test for it.
Without the fix, the error is:
ninja: error: 'ct2.pyx', needed by 'libdir/ct2.cpython-39-x86_64-linux-gnu.so.p/ct2.pyx.c',
missing and no known rule to make it
Add a method to downgrade an option to disabled if it is not used.
This is useful to avoid unnecessary search for dependencies;
for example
dep = dependency('dep', required: get_option('feature').disable_auto_if(not foo))
can be used instead of the more verbose and complex
if get_option('feature').auto() and not foo then
dep = dependency('', required: false)
else
dep = dependency('dep', required: get_option('feature'))
endif
or to avoid unnecessary dependency searches:
dep1 = dependency('dep1', required: get_option('foo'))
# dep2 is only used together with dep1
dep2 = dependency('dep2', required: get_option('foo').disable_auto_if(not dep1.found()))
```

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.

This method simplifies the conversion of Feature objects to booleans.
Often, one has to use the "not" operator in order to treat "auto"
and "enabled" the same way.
"allowed()" also works well in conjunction with the require method that
is introduced in the next patch. For example,
if get_option('foo').require(host_machine.system() == 'windows').allowed() then
src += ['foo.c']
config.set10('HAVE_FOO', 1)
endif
can be used instead of
if host_machine.system() != 'windows'
if get_option('foo').enabled()
error('...')
endif
endif
if not get_option('foo').disabled() then
src += ['foo.c']
config.set10('HAVE_FOO', 1)
endif

We need to pass any generated sources down the CustomTarget
inititalizers so that they will generate a dependency correctly,
otherwise we get race conditions.
This partially reverts commit add502c648.
In 'linkshared' test, annotate cppfunc() as imported, so an indirection
through an import stub is generated, avoiding a relocation size error
when building using gcc for Cygwin with LTO on.
Align with the example of how to write this portably in [1].
The 'c' language part of that test already gets this right.

This is so dumb, we can just insert C for you without you having to know
that you're using C under the hood. This is nicer because:
1) Meson doesn't make the user add a language they're not explicitly
using
2) If there was ever an implementaiton of Vala that didn't use C as
it's assembly language, this wouldn't make any sense.
We need to escape space in variables that gets into cflags or libs
because otherwise we cannot split compiler args when paths contains
spaces. But custom variables are unlikely to be path that gets used in
cflags/libs, and escaping them cause regression in GStreamer that use
space as separator in a list variable.
install_scripts used to replace @BUILD_ROOT@ and @SOURCE_ROOT@ but it
was not documented and got removed in Meson 0.58.0. gnome.gtkdoc() was
relying on that behaviour, but it has always been broken in the case the
source or build directory contains spaces.
Fix this by changing get_include_args() to substitue paths directly
which will then get escaped correctly.
Add a unit test that builds GObject documentation which is where this
issue has been spotted.
Fixes: #8744
With this change File objects created with the builtin files() function
can be used with the fs submodule like normal strings.
All methods that seem reasonable support FileOrSting arguments.
For example fs.exists() still only takes str arguments because meson
already ensures that File objects do exist when creating them with files().
Each user facing function of the fs module has an additional FeatureNew
check when used with File objects.
The test cases for fs are extended appropriately with tests for File objects.
This is just forcing the usage of -include as c_args, even though this
particular case can happen easily when this is provided via a dependency
cflags.
We also ensure that both the headers are included by using locale
definitions.
We need to konw on rconfigure which options have already bee set not
just for the super project, but also for the subproject. However, using
first_invocation is not sufficient, as a reconfigure could add a new
subpproject that wasn't present before, and we need to initialize that
project's builtins.
