Set MESON_CI_JOBNAME for all CI jobs which run project tests.
(Note that ${{ github.job }} is the literal job.id used in the yaml, not
any name given to the job with job.id.name, and so is the same for all
matrix entries, and thus not suitable for our purposes there).
The build_machine.system() value we should be matching against is
'darwin', not 'macos', so this was expected to skip everywhere.
Unfortunately, fixing this reveals that this test skips in our macos CI
runs also, (I think) because brew doesn't (normally) provide frameworks,
just pkgconfig files.
So, also skip this test there, which means it doesn't run anywhere in
CI currently.
This restricts the pipeline from running on 'non-code' pushes and PRs in
the same way that GitHub workflows which run project tests are (although
the syntax is different, and must be made more explicit as wildcards
aren't supported).
The Environment object constructor accepts None as build_dir (for quite
a while now), so don't bother with creating a temporary directory for
use as the build_dir, if we're not going to need it.
Future work: Environment.__init__() sets scratch_dir to '' if build_dir
is None, which seems a little wonky, as it isn't a path.
Remove hard-coded framework test skip logic in skippable(), instead
annotate test.json with environments in which skip is expected.
(Mainly this is done with by testing the value of MESON_CI_JOBNAME now
set for linux jobs)
If the required LLVM modules can't be found, skip the LLVM framework
test, rather than succesfully doing nothing.
(This optionality is a leftover from before #7379)
(At the moment, OpenSuse provides dynamic-only LLVM. The cmake method
still finds LLVM, when a static LLVM is requested, but fails to find any
modules. This might be a bug in the cmake method of the LLVM
dependency.)
Plan to replace the hard-coded list of 'may be skipped' framework tests in
skippable() with annotations in test.json which record 'will be skipped
in these specific CI jobs'.
If the value of the MESON_CI_JOBNAME env var (an arbitrary string
expected to be unique for each CI configuration) contains any of the
strings in the `skip_on_jobname` key in test.json, the test is expected
to output MESON_SKIP_TEST.
Unexpected skips or runs are treated as an error.
Future work: Maybe we should add additional count categories 'unexpected
skip' and 'unexpected not skipped', rather than counting those as 'skipped'
and 'failed', respectively.
"meson setup" is resolving symlinks for the build directory in
validate_core_dirs. For consistency with it, do the same when
the build directory is passed via -C to devenv, dist, init, install
and test.
This ensures for example that the path to test dependencies is
computed correctly in "meson test".
