Work around a bug in Meson versions < 0.50.0 where
`--wrap-mode=nodownload` would disable the use of fallback subprojects,
even if they’d already been downloaded, with the message:
```
Cross dependency libpcre found: NO (tried pkgconfig and cmake)
Cross dependency libpcre found: NO (tried pkgconfig)
Not looking for a fallback subproject for the dependency libpcre because:
Use of fallbackdependencies is disabled.
meson.build:1998:2: ERROR: Dependency "libpcre" not found, tried pkgconfig
```
This workaround can be dropped in the near future when we bump our Meson
dependency to something less ancient. We have a self-imposed requirement
to be buildable using what’s packaged in Debian Stable, which is
currently Meson 0.49.2 — but the new Debian Stable release is coming
soon, with an updated Meson.
Using `--force-fallback-for=libpcre` would have been a more constrained
workaround, but unfortunately that argument didn’t exist in Meson 0.49.

This should maintain equivalent functionality, apart from that now you
have to pass `--force-fallback-for libpcre` to `meson configure` in
order to use the subproject; rather than specifying
`-Dinternal_pcre=true` to use the internal copy.
This also fixes#642, as the wrapdb copy of libpcre is version 8.37.

Rather than specifying the default branch explicitly, allow the origin
to choose it. Specify the `--single-branch` option explicitly to make it
clear the CI only needs one branch; this is however already implied by
the `--depth` option so is not strictly necessary.
This will help avoid breakage if gobject-introspection changes its

Run `systemd-machine-id-setup` when creating the image, so that

So the tests can access `/var/lib/dbus/machine-id`. This is not a
behaviour change relative to older behaviour on CI.
In future, it might make more sense to revert this commit and change the
CI scripts so they symlink
`/home/user/glib-installed/var/lib/dbus/machine-id` to the system
machine ID; or ensure that `/etc/machine-id` exists on all the CI
machines. That’s too complicated to do right now though.

It doesn’t seem to be possible to use `only:changes` from a branch
pipeline extending `.only-default` and have it correctly trigger when
`*.sh` or `*.py` files are modified.
We possibly need to convert all our pipelines to be merge-request-only,
but that’s an avenue I’ve been down before and I couldn’t get it to
work. Using
[`workflow:rules`](https://docs.gitlab.com/ee/ci/yaml/README.html#workflowrules)
might fix that, but I don’t have time to rework the entire CI to use
that now.
So in the meantime, move the SH and Py checks into the existing
style-check job so we’re not always spinning up two additional container
instances on every merge request.

gitlab will drop cmd.exe support with GitLab 13 so I took the opportunity to
add new runners with Windows 2016 and powershell as default.
These runners are tagged with win32-ps instead of win32. The old runners
will be switched off in the coming weeks.
The main difference is that all commands and env expansions use powershell
and Windows 2016 instead of 2012r2.
In cases where performance are critical it can be useful to disable
checks and asserts. GStreamer has those options too, using the same name
and setting them yielding means we can set those options on the main
project (e.g. gst-build) and glib will inherit the same value when built
as subproject.
This will help to debug CI issues that are related to us running in
a container that might have unusual capabilities, mount points,
filesystems etc., such as (probably) #2027, #2028, #2029.

This is required to be able to build the doc. The debian docker is still
pinned to 0.49.2 which ensure we can build with both versions of meson.
Meson 0.52.0 warns about adding -Wall flag manually, we can remove that
because warning_level=1 (the default) option already implies it.
This has the side effect of always rebuilding the doc at each build when
gtk_doc option is enabled (not by default). Most importantly, this will
enable doc check on our CI.
Using the same approach as we have for code style checks (the
`style-check-diff` CI job), check the diff for any banned keywords like
‘TODO’, and also check the commit messages.
The keyword ‘TODO’ is often used by developers to indicate a part of a
commit which needs further work, and hence which shouldn’t yet be merged.

Since we added `only: [merge_requests]` for the `style-check-diff` job,
that started running detached pipelines only for merge requests and only
containing that job, and not running the other jobs for merge requests
(only for branches).
That wasn’t the intention.
Follow the guide on
https://docs.gitlab.com/ee/ci/merge_request_pipelines/index.html#excluding-certain-jobs
to ensure that all jobs (including `style-check-diff`) are run for merge
requests.
This means we can no longer unconditionally use
`${CI_MERGE_REQUEST_TARGET_BRANCH_{NAME,SHA}}`, since they are only
defined for jobs which are running against a merge request rather than a
branch. Instead, use some `git rev-list` magic from
https://stackoverflow.com/a/4991675/2931197 to find the newest common
ancestor commit between the detached head that CI is running on, and the
known or likely target branch. Do the style check against the diff
between the newest common ancestor commit and the detached head.
(Note that `${CI_MERGE_REQUEST_TARGET_BRANCH_SHA}` was never actually
defined for any of our pipelines, since it’s only available for CI
pipelines running on merged branches, which is a GitLab Premium
feature. Oops, my bad.)
In order to find the newest common ancestor commit, we need to pull the
upstream remote, since the CI pipeline might be running on a fork of the
main repository where various branches (particularly `master`) are out
of date.

The build artifacts from earlier jobs in the pipeline all use the
`_build` directory. When they are copied in to the scan-build job, they
are probably marked as read-only. This means that the `meson scan-build`

Use Meson’s support for running scan-build (Clang’s static analyser)
against the build, so that we get static analysis of each pipeline. Add
it in a new pipeline stage, after code coverage, so that we don’t waste
resources on it unless the unit tests pass — a static analysis build
takes perhaps 10× as long as a normal GCC build.
https://mesonbuild.com/howtox.html#use-clang-static-analyzer
Currently, the static analysis results are uploaded as artifacts, but
the job will always succeed (regardless of whether there are any bugs
found in the analysis).
Currently, a large number of reports are outputted by the analyser,
which need to be fixed before we can gate the pipeline on it.
Furthermore, in order to get scan-build to exit with a non-zero status
if any bugs are found, we need to depend on Meson ≥ 0.49.0, which
contains the fix https://github.com/mesonbuild/meson/issues/4334,
allowing us to add the following to .gitlab-ci.yml:
```
variables:
# Exit with a non-zero status if any bugs are found

GitLab can show the results of a CI pipeline if the pipeline generates a

This effectively renders those tests useless (since realistically nobody

Since we are unable to promote our FreeBSD runner to a shared runner,
we can only enable it in GNOME group. This should avoid problems when
submitting merge requests from forks.
While we can’t add markers to the macro implementations to cause lcov to
ignore them automatically, we can change our lcov configuration to
ignore all calls to them.
See https://github.com/linux-test-project/lcov/issues/44.
This causes all the un-takeable branches and un-reachable assertions to
be ignored by our code coverage, which bumps our statistics:
• Lines: 74.9% → 74.8%
• Functions: 82.3% → 82.3%
• Branches: 53.3% → 64.2%
The rationale is that nobody should be testing programmer error
handling, as g_return_*if_fail() are used to guard against — so it’s not
reasonable to count missed branches like that in code coverage
statistics.

Similar issue was fixed with commit f929d148, but it's happening again.
Define G_MESSAGES_DEBUG=all when running CI to ensure we won't regress
anymore.
See comment in !151. Using the "--initial" option of lcov we collect
the coverage of all compiled files and merge them later into the final
report. This way we can see which files are built but never executed
by the test suite.
Because the --initial switch also collects files in the ccache directory
we have to point it to the build directory instead, which in turn breaks
--no-external. Instead of using --no-external in the collection step,
filter out any files not in the source tree in the final coverage job
through a path filter.
This requires meson >= 0.47.0 otherwise building the doc fails:
https://github.com/mesonbuild/meson/issues/3379
While at it, no need to to pass --prefix --libdir to meson, other CIs
don't have them.
- Split the download part into a separate script to so docker keeps that
step in cache and avoid redownloading it.
- With API level >= 28 libiconv is not needed anymore because it's part
of Android's libc.
- Generate standalone toolchains to reduce the docker image size. It's
also easier because it doesn't need to pass sysroot args.
- Use clang compiler because gcc is deprecated in this Android NDK and
will be removed in the next release.
Job names in gitlab pipeline view gets truncated to "fedora-meson-..."
for all jobs which is not really useful. All our CIs are using Meson,
and the host distro is not relevant when doing cross builds.
We should be testing latest NDK release but keep using API level 21 to
ensure GLib does not start using newer APIs. We could also later add a
runner for latest API level 28 which includes iconv API in Android's
libc so we don't need GNU libiconv anymore.
The default `when: on_success` means no artifacts are exported when the
tests fail, which is precisely when we want to see the artifacts.
Always export them, and rely on GitLab to garbage collect them as
appropriate (typically after 30 days, I think).

This adds to the CI a cross build for Android NDK r16 API 21 (because

GNU iconv must be built manually into our docker image because Android
NDK doesn't seems to ship it. The latest NDK r17 API 28 has iconv.h but
iconv_open() symbol isn't found by the linker. Looks like broken NDK.
libffi also needs to be built manually because the meson subproject
doesn't support building for Android platform. It needs a recent RC
release because latest stable release is 4 years old and fails to
build.

GitLab can then use this to annotate each pipeline with its code
coverage statistics. It can only use one figure, so we choose lines
(rather than function or branch coverage) since it’s the most intuitive
figure.

Overall coverage rate:
lines......: 76.7% (108959 of 142122 lines)

We're mostly interested into building and testing everything that gets
pushed to the repository — including merge requests.
When pushing tags, though, we should assume we're spinning a release, so
let's run the dist target, and store the tarball, and the generated

The Dockerfile for the image used for the build is included in tree, and
