desktop-app-info test may fail when repeated with multiple concurrent
processes because the actions test relies on checking the existence of

meson test -C _build desktop-app-info -t 0.3 --repeat 80
We may end up in timeout errors, because we are waiting for files that
have been already deleted by other processes.
To avoid this, let's rely on writing the files on `$G_TEST_TMPDIR` env
variable, that is always set and unique, given that we're using the
G_TEST_OPTION_ISOLATE_DIRS test option.
We were testing the case in which we were opening an actual file, and so
potentially using a fd-list, however we were missing the case in which a file
was not existent.
And in such case we are incidentally hitting a leak now.
All of these warnings indicate programmer error, so critical is most

Exceptions: deprecation warnings are just warnings. Also, warnings that

Enumeration members should either have the name of the type as their
prefix, or they should all have the same prefix.
The "default flags" enumeration member for GApplicationFlags is
unfortunately named G_APPLICATION_FLAGS_NONE, while every other member
of the same type has a G_APPLICATION prefix. The result is that the nick
name of the enumeration member is "flags-none", and that language
bindings will have to use something like
Gio.ApplicationFlags.FLAGS_NONE.
To fix this API wart, we can deprecate the FLAGS_NONE member, and add a
new DEFAULT_FLAGS.
A shell one-liner was enough to set GIO_LAUNCHED_DESKTOP_FILE_PID,

Ideally we would call sd_journal_stream_fd() in a process that will
exec the real program, otherwise it will report the wrong process ID
in the Journal, but we can't easily do that in a forked child when
using posix_spawn() for subprocesses.

The dominant implementations of the well-known session and system
message buses are the reference implementation from the dbus project
(dbus-daemon) and the sd-bus-based reimplementation dbus-broker, both
of which have correct implementations for EXTERNAL authentication with
an unspecified authorization identity.
This makes it reasonably safe to assume that the well-known message
buses can cope with the unspecified authorization identity, even if we
cannot make the same assumption for custom servers such as the ones
used in ibus and gvfs (which might have been started with an older
GLib version before upgrading GLib in-place).

It doesn't make sense for a proxy resolver to return NULL without an
error on the first call. Whereas a DNS resolver would do this to
indicate that a query completed successfully but found no results, a
proxy resolver should return "direct://" instead. Therefore, if we are
going to return NULL, we ought to have an error as well. Let's make sure
this actually happens by adding some fallback errors just in case
GProxyResolver feeds us weird results.
Additionally, we should not return any errors except
G_IO_ERROR_CANCELLED after the very first iteration. This is an API
contract of GSocketAddressEnumerator. Let's add some checks to ensure
this.
Note that we have inadequate test coverage for GProxyAddressEnumerator.
It's tested here only via GSocketClient. We could do a bit better by
testing it directly as well. For example, I've added tests to see what
happens when GProxyResolver returns both a valid and an invalid URI, but
it's not so interesting here because GSocketClient always uses the valid
result and ignores the error from GProxyAddressEnumerator.
Fixes#2597
This has no practical impact, since it's only a test, and none of the
test code would have hit this bug, but the GTestProxyResolver's check to
see if the URI scheme is simple:// currently only compares the first
four bytes of the string, so it's actually only checking for the "simp"
and would match anything else after that, e.g. "simpleton://". This is
surely not intended.
This was causing intermittent failures on macOS, depending on whether
the tmpdir ended with a `/` or `/some-dir`. `g_strrstr()` is not the

```

Despite the name, we still used blocking calls to get the default app
for URI, now that we have an async implementation of the API to get the
default implementation for URI scheme, we can remove the blocking calls.
We did not check whether this function worked before, so add a simple
test case for it, providing some test functions to make it possible to
reply the same behavior
While it's possible to create a directory synchronously via
g_dir_make_tmp(), there's no such API that performs it asynchronously.
So implement it using GFile, using a thread to perform such task.
It seems this script has potentially never worked properly under Python
3. It’s supposed to list all the `_get_type()` functions it can find in
the GIO headers, but since the regex string passed to `re.search()` was
not a Python regex, nothing was matching.
Fix that, and do another few small cleanups to the script.
This makes the `defaultvalue` test not skip all the types.

This is a fallback timeout to abort the test if the expected number of
messages aren’t seen in time. However, when running the test under
valgrind it will take longer and sometimes spuriously trigger the
timeout.
There’s no point in having an abort timeout inside the test: the test
runner (Meson) already provides one for us, which we can adjust with a
multiplier when running under valgrind.
So removes the timeout from within the test. This should fix the
gnotification test under valgrind.

When checking that the connection has the expected number of refs, the
test would block on a `GMainContext` iteration for up to 3s before
waking up and failing (if the refcount was still not as expected).
This check was written in the expectation that changing the refcount of
the connection would only happen due to dispatching a source on
`GMainContext` — hence the `GMainContext` would wake up as the refcount
changed.
That’s probably not actually true though. It might be the case that the
connection’s refcount is changed on from the GDBus worker thread, which
would not cause any wakeups on the main thread’s `GMainContext`.
In this case, the `GMainContext` iteration in
`assert_connection_has_one_ref()` would block for the full 3s, and then
wake up and notice the refcount is correct (then the test would
proceed).
That’s fine, apart from the fact that `test_threaded_singleton()` does
this 1000 times. If the slow case is hit on a significant number of
those test runs, the test will take around 3000s to complete, which is
significantly more than meson’s test timeout of 360s. So the test fails
with something like:
```

```
From this log, it can be seen that the sleep is happening on a different
`GMainContext` every other time, so the test *is* making progress.
Assuming this is a correct diagnosis (it’s a lot of guessing), this
commit tries to fix the test by adding a wakeup timeout to the
`GMainContext` in `assert_connection_has_one_ref()`, which will wake it
up every 50ms to re-check the exit condition.
This polling approach has been taken because it doesn’t seem feasible to
make sure that every `g_object_ref()`/`g_object_unref()` call on a
`GDBusConnection` causes the main context to wake up.

There’s (deliberately) a bit of race in implementing/handling
`CloseBeforeReturning()` in `gdbus-method-invocation.c`. If the server
closes the D-Bus connection early, the client may exit with `SIGTERM` if
`GDBusConnection:exit-on-close` is set. We don’t want that, as the test
is trying to check that the default handling of a D-Bus method return
after a connection has closed works.

Windows DNS APIs provide much more structured results which don’t need

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.
