wraps from subprojects are now merged into the list of wraps from main
project, so they can be used to download dependencies of dependencies
instead of having to promote wraps manually. If multiple projects
provides the same wrap file, the first one to be configured wins.
This also fix usage of sub-subproject that don't have wrap files. We can
now configure B when its source tree is at
`subprojects/A/subprojects/B/`. This has the implication that we cannot
assume that subproject "foo" is at `self.subproject_dir / 'foo'` any
more.

dirname is confusing because the name of a subproject does not always
match its directory name, the wrap file can define another directory.
For example foo.wrap will often extract the subproject into foo-1.2
directory, in that case the subproject name is 'foo' and the subproject
directory is 'foo-1.2'.

cmake: Cross compilation support
|

You could always specify a list of tests to run by passing the names as
arguments to `meson test`. If there were multiple tests with that name (in the
same project or different subprojects), all of them would be run. Now you can:
1. Run all tests with the specified name from a specific subproject: `meson test subprojname:testname`
1. Run all tests defined in a specific subproject: `meson test subprojectname:`
Also forbid ':' in test names. We already forbid this elsewhere, so
should not be a big deal.

Allow blocking/forcing automatic subproject search
|
|
|
|
|
|
Sometimes, distros want to configure a project so that it does not
use any bundled library. In this case, meson.build might want
to do something like this, where slirp is a combo option
with values auto/system/internal:
slirp = dependency('', required: false)
if get_option('slirp') != 'internal'
slirp = dependency('slirp',
required: get_option('slirp') == 'system')
endif
if not slirp.found()
slirp = subproject('libslirp', ...) .variable('...')
endif
and we cannot use "fallback" because the "system" value should never
look for a subproject.
This worked until 0.54.x, but in 0.55.x this breaks because of the
automatic subproject search. Note that the desired effect here is
backwards compared to the policy of doing an automatic search on
"required: true"; we only want to do the search if "required" is false!
It would be possible to look for the dependency with `required: false`
and issue the error manually, but it's ugly and it may produce an error
message that looks "different" from Meson's.
Instead, with this change it is possible to achieve this effect in an
even simpler way:
slirp = dependency('slirp',
required: get_option('slirp') != 'auto',
allow_fallback: get_option('slirp') == 'system' ? false : ['slirp', 'libslirp_dep'])
The patch also adds support for "allow_fallback: true", which is
simple and enables automatic fallback to a wrap even for non-required
dependencies.
|

Force_fallback is not an interpreter keyword argument, and there
is no reason to handle it as one since it is not used anywhere
else (and in fact is explicitly ignored by get_dep_identifier).
Use a Python keyword argument instead, which makes the code
simpler.

Just saying "it failed" is accurate, but not useful to helping someone
figure out why it failed. Giving them the stdout and stderr (like we
might with compilers) should help people resolve the issue.

Currently if you change the `choices` field in the meson_options.txt
file, no update will be done until `meson setup --wipe` is called. Now
if the choices change then the options will be properly merged.
If the currently select value is still valid it is guaranteed to be
kept, if it is now invalid the new default value will be used and a
warning will be printed.
Fixes #7386

`pathlib.Path.glob()` also returns directories that match source
filenames (i.e. a directory named `test.h/`), but `clang-format` and
`clang-tidy` fail when handed a directory. We manually skip calling
`clang-format` and `clang-tidy` on those directories.
|
|
This is required to make the various keys in the [user options] section
work the same as they do in the meson_options.txt file, where we don't
have any rules about case sensitivity.
There is some risk here. Someone may be relying on this lower by default
behavior, and this could break their machine files.
Fixes #7731

Projects that specify b_pie=true clutter build logs with the warning:
clang: warning: argument unused during compilation: '-pie' [-Wunused-command-line-argument]
No option is needed to produce PIE binaries because ld64 is making PIE
executables on 10.7 and above by default, as documented in ld(1).

Fixes bug #589. When generating string from file object, it didn't take subdir

Full annotations for the Compiler package

- Remove platform from env so that msbuild does not try to compile
e.g. configuration debug|x86

Unlike MSVC and ClangCl it needs to call into it's own compiler check
args

The implementation of the link variant was what should have been the
compiler variant, and there was no valid compiler variant, which meant
it was getting C code.
|
|
|
|
We don't need it anymore, and it would be problematic for the D
compilers.
|
|
This abstraction is really useful, and most compilers could use it
(including D). It also will allow the Gnu mixins to work properly
without the CLikeCompiler in their mro.
|
|
|
|
Instead of trying to override the compiles() method, which gets skipped
in a bunch of cases.
|
|
This is groundwork to put _build_wrapper in the base Compiler, which is
needed to make the D compilers truly type safe.

So that we can actually use it anyplace that an OptionDictType could be
used. I've also done a bit optimizing/simplifying of the implementation.
This is needed for cuda, as it returns an OptionOverrideProxy where we
ask for an OptionDicType
