Some license identifiers are ambiguous (e.g. "GPL3"). The SPDX license
identifiers avoid this by providing standardized and unique identifiers
(e.g. "GPL-3.0-only" or "GPL-3.0-or-later" for the previous example).
Because SPDX short-form identifiers are also both human- and
machine-readable we should recommend them in the documentation.
More information (advantages, details, etc.) can be found here:

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.
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.
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
This is a test for https://github.com/mesonbuild/meson/pull/7021, to
verify that `link.exe` uses the correct architecture when targeting
ARM64. Can be extended to other cross targets later.
Split out tests (and parts of tests) which require a native compiler
from the 'common' suite to a new suite called 'native', so we can
selectively avoid running those tests when only a cross-compiler is
available.
Also move test '211 cmake module' to 'cmake' suite, since it appears
that the way we use cmake requires a native compiler.
This removes the check for "mingw" for platform.system(). The only case I know
where "mingw" is return is if using a msys Python under a msys2 mingw environment.
This combination is not really supported by meson and will result in weird errors,
so remove the check.
The second change is checking sys.platform for cygwin instead of platform.system().
The former is document to return "cygwin", while the latter is not and just
returns uname().
While under Cygwin it uname() always starts with "cygwin" it's not hardcoded in MSYS2
and starts with the environment name. Using sys.platform is safer here.
Fixes#7552
According to the specification:
https://testanything.org/tap-specification.html#skipping-tests
The harness should report the text after # SKIP\S*\s+ as a reason for
skipping.
(it's not exactly like the TODO directive, the phrasing/presentation of
the spec could be improved).
* mtest: TestResult.SKIP is not a failure
If some but not all tests in a run were skipped, then the overall result
is given by whether there were any failures among the non-skipped tests.

* Add test-cases for partially skipped TAP tests
issue7515.txt is the output of one of the real TAP tests in gjs, which
failed as a result of #7515. The version inline in meson.build is
a minimal reproducer.

Windows Git users with symlinks have a constantly dirty repo from

This extends the 109 generatecode test case to also define a test, so
coverage can really detect something.
We have experimented with the module for about a year in a qemu
branch (https://wiki.qemu.org/Features/Meson), and we would like to
start moving the build system to meson. For that, keyval should have
the stability guarantees.

We don't need the legacy variable name system as for dependency()
fallbacks because meson.override_find_program() is largely used already,
so we can just rely on it.
The value for that key must be a coma separated list of dependecy names
provided by that subproject, when no variable name is needed because the
subproject uses override_dependency().
