libgamin was last released in 2007 and is dead
[upstream](https://gitlab.gnome.org/Archive/gamin). Distributions may
still ship it (although Fedora no longer does), but we want people to
use inotify on Linux since it’s actively supported.
BSDs use kqueue. Windows uses win32filemonitor.
FAM might still be used on some commercial Unix distributions, but there
are no contributors from those distributions, and certainly no CI for
them to prevent regressions.

Reworked to no longer use test fixtures, as it’s simple enough to build
the response header in each test.
The tests are built on Unix only, as they test the parsing code in
`g_resolver_records_from_res_query()`, which is Unix-specific. The
Windows DNS APIs provide much more structured results which don’t need
parsing.
The SONAME of libutil varies between architectures, so the logic to find
the SONAME of libutil was only correct for native builds (Linux on
Linux), not for cross-builds. The regular expression was also not
sufficiently broad to match the SONAME used on the alpha architecture,
which is apparently libutil.so.1.1.
Instead of screen-scraping the output of ldconfig and using that to
dlopen the library that contains openpty, it seems more reliable to
emit a link-time reference to openpty and let the linker do its job.
It's also less code.

This reverts commit 5aa03882ca.
It fails to compile on newer Meson versions with
`--fatal-meson-warnings` due to:
```
WARNING: Project targeting '>= 0.52.0' but tried to use feature introduced in '0.54.0': variables arg in declare_dependency.
gio/meson.build:833:0: ERROR: Fatal warnings enabled, aborting
```
That happens regardless of the fact that we’ve correctly limited the use
of the `variables` argument to only when building with Meson ≥ 0.56.
Unfortunately Meson can’t statically detect that the argument is
conditional.
Bumping GLib’s Meson dependency is too much work right now, so this MR
unfortunately has to be reverted.
This allows applications to get their value regardless whether glib is a

`mock-resolver.c` is a mock implementation of `GResolver` used in the
`network-address` tests. It returns resolver results, and implements
timeouts, as directed by the test calling it.
In particular, it allows the IPv4 and IPv6 resolver results to be
returned using independent delays. This allows code paths which deal
with IPv4 and IPv6 results being returned at different times to be
tested, as the ‘Happy Eyeballs’ spec mandates various hard-coded
timeouts for returning the best results it can in a reasonable
timeframe.
Previously, `mock-resolver.c` implemented the timeouts by handling
`lookup_by_name()` in a `GTask` worker thread, and calling `g_usleep()`
for the timeout. This seemed to cause occasional CI failures, such as
https://gitlab.gnome.org/GNOME/glib/-/jobs/1843454, where a resolver
error would be returned rather than the expected results:
```
ok 52 /network-address/happy-eyeballs/ipv4-error-ipv6-first
\# GLib-GIO-DEBUG: IPv4 DNS error: IPv4 Broken
(/var/tmp/gitlab_runner/builds/Ff4WDDRj/0/GNOME/glib/_build/gio/tests/network-address:18428): GLib-GIO-DEBUG: 09:03:08.587: IPv4 DNS error: IPv4 Broken

stderr:
**
GLib-GIO:ERROR:../gio/tests/network-address.c:586:got_addr: assertion failed (error == NULL): IPv4 Broken (g-io-error-quark, 24)
```
While I’ve been unable to reproduce these failures locally, I suspect
they might be down to thread spawning occasionally taking long enough on
a CI runner to change the ordering of the timeouts, such that the ‘Happy
Eyeballs’ algorithm returns a different set of results from what the
test expects.
So, this commit rewrites part of `mock-resolver.c` to implement timeouts
in the main thread, rather than in a worker thread. That should
eliminate the delays in spawning threads, and should mean that the
timeout sources in `mock-resolver.c` are attached to the same
`GMainContext` as those from the ‘Happy Eyeballs’ algorithm which are
monitoring them, so a total order over the timeouts can be guaranteed.
Of course, I might be completely wrong since this is just a guess and I
can’t properly test it since I can’t reproduce the failure. Worth a try.

Test failures were previously ignored on macOS because there are 12
tests which consistently fail (and have not yet been fixed, because
there are no regularly active macOS maintainers for GLib; you could help
here!).
However, this means that new test failures can’t be spotted.
So, explicitly mark those 12 tests as `should_fail` on macOS, and then

As they use `g_test_dbus_*()`, they depend on dbus-daemon, so move them
to the part of the Meson file which lists those tests.
This disables them running on platforms which don’t have `dbus-daemon`
available. Arguably, this should be done by returning an error from
`g_test_dbus_up()` and then calling `g_test_skip()`, so the test is
correctly recorded as having been skipped. But that’s a fix for another

The retry loop for acquiring the lock for the authentication cookie file
currently tries to acquire the lock for 0.5s, then gives up, assumes the
lock file is stale, and deletes it.
That’s great if the lock file *is* stale because it’s been left there by
a crashed process.
It’s not so great if the lock file just happens to have been there every
time this process checked, because the cookie file is highly contested
while (for example) running lots of parallel unit tests.
Check for that situation by comparing the mtime of the lock file and
continuing to retry if it’s changed.
