We may end up in timeout errors, because we are waiting for files that

To avoid this, let's rely on writing the files on `$G_TEST_TMPDIR` env

G_TEST_OPTION_ISOLATE_DIRS test option.

And in such case we are incidentally hitting a leak now.

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.

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 is a fallback timeout to abort the test if the expected number of

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

multiplier when running 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.

The SONAME of libutil varies between architectures, so the logic to find

which is apparently libutil.so.1.1.

`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

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.

The test results weren’t being freed.
This makes the `network-address` test clean under memcheck for me.

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
make other test failures cause failure of the CI run.
We can track the process of fixing those 12 tests on #1392 and #1251.

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
time.

Having compared the debug output, it doesn’t show anything unusual
happening that can’t already be seen from other output, for this test.
This is a partial revert of 8fd71dccc5. The debugging output it added to
other tests may still be useful.

As with the previous commit, this isn’t needed for GLib’s tests to work
correctly, but is probably needed in other projects which might be
tempted to copy and paste the Meson tooling from GLib.

This isn’t needed to make the tests any better (it doesn’t really affect
them), but is probably needed for anyone who copies this Meson code in
order to add `glib-compile-resources` support to their project. It’s
pretty unlikely that someone would want to compile *and export* a
resource from a shared library.

Credentials are often used to check peer processes details.
With AF_UNIX sockets on Windows, SIO_AF_UNIX_GETPEERPID can
be used to retrive the peer PID.
We will probably introduce more advanced mechanisms later on, though,
but I am not a Windows API expert.

Glib cannot be built statically on Windows because glib, gobject and gio
modules need to perform specific initialization when DLL are loaded and
cleanup when unloaded. Those initializations and cleanups are performed
using the DllMain function which is not called with static builds.
Issue is known for a while and solutions were already proposed but never
merged (see: https://gitlab.gnome.org/GNOME/glib/-/issues/692). Last
patch is from version 2.36.x and since then the
"constructor/destructor" mechanism has been implemented and used in
other part of the system.
This patch takes back the old idea and updates it to the last version of
glib to allow static compilation on Windows.
WARNING: because DllMain doesn't exist anymore in static compilation
mode, there is no easy way of knowing when a Windows thread finishes.
This patch implements a workaround for glib threads created by calling
g_thread_new(), so all glib threads created through glib API will behave
exactly the same way in static and dynamic compilation modes.
Unfortunately, Windows threads created by using CreateThread() or
_beginthread/ex() will not work with glib TLS functions. If users need
absolutely to use a thread NOT created with glib API under Windows and
in static compilation mode, they should not use glib functions within
their thread or they may encounter memory leaks when the thread finishes.
This should not be an issue as users should use exclusively the glib API
to manipulate threads in order to be cross-platform compatible and this
would be very unlikely and cumbersome that they may mix up Windows native
threads API with glib one.
Closes#692
