g-ir-scanner does not convert relative -L paths to runtime paths which
are added to -Wl,-rpath and LD_LIBRARY_PATH / DYLD_LIBRARY_PATH
/ PATH. This means that the local library will either not be found at
runtime (while building introspection data), or the system-wide
library will be picked instead.
See: giscanner/ccompiler.py:get_internal_link_flags() in
gobject-introspection for more details.
For an ELF targets, shared_module() builds a module with SONAME field
(using -Wl,-soname argument). This is wrong: only the shared_library()
needs SONAME, while shared_module() does not. Moreover, tools such as
debian's dpkg-shlibdeps use presence of SONAME field as an indicator
that this is shared library as opposed to shared module (e.g., for the
module it is okay to have unresolved symbols which are imported from
the executable which loads the module, while a library should have all
symbols resolved).
This was in fact already the behavior on Darwin; extend it to ELF
targets as well.

code coverage may be interesting to some people as an informational
update, but it's really fragile and sometimes obscure, and overall we
would really like to NOT have most PRs reporting a red X in the CI
overview, when all project/unittests succeeded but codecov decides that
by some inscrutbale metric, coverage by % has dropped.
Elegant refactorings are penalized, because removing lines of code or
rewriting them to be more compact, means the overall percentage of
covered code is "less", even though no uncovered code got added.
Even worse, the coverage reports often erroneously complain that a PR
has "added lines #L<num> - L<num> were not covered by tests" even though
github helpfully points out they are "Unchanged files with check
annotations". Or more generally, codecov claims that coverage has
dropped in code which the PR can't touch.
The whole thing is just too much of a source of trouble. So, configure
codecov to consider all PRs as successful no matter what. It is still
welcome to leave informational comments, though.
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.
