Add a test for monitoring an existing local file, with the
WATCH_HARD_LINKS flag specified. This would previously cause a crash;
now it doesn’t.
This test contains a FIXME where I suspect we should be getting some
additional file change notifications from changes made through the hard
link; this requires further follow up and probably further fixes to our
inotify backend.

This gets the G_FILE_MONITOR_WATCH_HARD_LINKS flag to the state where it
doesn’t cause crashes, and essentially acts as a no-op. It will not yet
actually monitor for changes made via hard links.

The call to _start() fills in the dirname, basename, and filename
arguments according to the following rules:
dir watches: dirname filled
file watches: dirname and basename filled
hardlink: filename filled
This doesn't map to how the current inotify backend works very nicely,
so we need to adjust things a bit when creating our "sub" objects.

This test will only work on machines which have IPv6 enabled and have a
local IPv6 interface with ID 1. On machines which don’t (such as AWS
servers, which we run CI tests on), the GResolver tests will fail with
G_RESOLVER_ERROR_INVALID. We can’t differentiate this kind of failure
(where we’d want to skip the test) from an actual failure (where we’d
want to fail the test), so the only other option is to drop this
particular test vector. I don’t think it’s a significant loss.
This is the last fix needed to get our CI tests working reliably on
jenkins.gnome.org.

There are various reasons why setting up a server might fail; it
reliably fails on AWS with IPv6 addresses (are we binding to the right
address?). Since we’re trying to test GSocket as a client, skip tests
where that happens.

While 333 runs is very likely to reproduce the bug, Milan has previously
reproduced it with as few as 9 runs. Since this test will be run by the
CI machinery quite often, a lower number of runs each CI run will still
probably catch any regressions over time.
This reduces the total test runtime from 33s to 2s.

When using g_network_monitor_get_default() from another thread, it’s
possible for network-changed events to be processed after an instance of
GNetworkMonitor has been disposed, causing use-after-free problems.
Fix that by moving some of the initialisation into the GInitable.init()
chain, rather than in a main context idle callback.
This includes a unit test which probabilistically reproduces the bug
(but can’t do so deterministically due to it being a race condition).

When using g_settings_bind(), if a range binding triggers a range check
failure, g_settings_binding_property_changed() will return early, but it
won't cleanup properly causing some leaks. The binding will also still
be marked as 'running', which causes an assertion failure when trying to

There's a race condition somewhere in GTestDBus that can result in
the next test being started at a time when g_bus_get() would still
return the connection that is in the process of closing. This can
be reproduced reasonably reliably by running the gapplication test
10K times in a loop.
Instead of relying on waiting for the weak reference to be released,
we can force the issue by clearing it.

This adds a null notification backend implementation for win32, purely
to avoid crashes due to a missing backend when applications use
GNotification. This backend does nothing except print a warning when a
notification is supposed to be emitted.
In future, it can be expanded to use win32 API to present toaster
notifications appropriately.

If glib-networking is installed and built with libproxy support, this
test will use it. If a proxy is set in the environment, we might get
correctly told to go through it for certain accesses. However, this isn't
going to work, because the testsuite monkeys with the network monitor to
tell it that all addresses - including the proxy - aren't reachable.
We're trying to check if adding networks to a GNetworkMonitor works in
general. Proxies just get in the way here, so let's use the built in
dummy proxy resolver which just tells us that all URLs are directly
accessible.

If something is nullable, it's always helpful to identify what NULL
means. Also, this is not the parameter for the .activate() vfunc, as we

The `mount_monitor` variable is only set if the boolean
`with_mount_monitor` variable is set to TRUE, but the compiler does not
know that, so it'll warn when calling `g_clear_object()` even if the
clearing operation is gated with the same boolean.
Initializing with NULL does not cost us anything, and eliminates a
conditional branch.

GSocketListener can keep internal references to itself for pending
accept() calls, which mean that it can stay alive (and keep listening
on ports) even after a user drops their last reference to it. They need
to call g_socket_listener_close() explicitly to avoid that.

There's no need to unconditionally print an error message if xmllint or
json-glib-format are not found when running glib-compile-resources is
called; we only need to warn if they are not available when we need
them. To avoid spamming the build logs, we can also warn once.

The glib-compile-resources tool has hand-rolled "open a temporary file"

Similarly to how glib-compile-resources can call xmllint to eliminate
whitespace in XML files to reduce their size inside a GResource, we can
use json-glib-format to achieve the same result.
The mechanism for using json-glib-format is the same, with a separate
environment variable if we want to direct glib-compile-resources to a
version of json-glib-format that is not the one in the PATH.

Normally, the list of mounts is filtered to exclude mounts in
/run/media/$username where $username is not the current user. However,
root can access all the mounts under /run/media/, regardless of the
username — so there’s no point in filtering out those mounts.
In some cases, filtering them out is harmful. In the case of a system
service which uses GVolumeMonitor, for example, filtering them out means
the service cannot see automounted USB sticks belonging to user
sessions.

Tighten up the validation of application IDs so they are always exactly
D-Bus well-known names. This is a slight change to the accepted format,
but since anyone using the API with an application ID which was
previously valid, but which was not a valid D-Bus well-known name, would
have received an error from D-Bus when their application tried to
register on the bus, I think this break is acceptable.
It will affect any applications which have application IDs which are not
valid D-Bus well-known names, and which use the G_APPLICATION_NON_UNIQUE
flag. From a quick search in Debian Codesearch, no C applications use
that flag.
Update the documentation to use the rules from the D-Bus specification,
including the latest advice discouraging use of hyphens:
https://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-bus
Update the tests:
• Add the examples from the documentation to validate them.
• Especially the venerable 7-zip.org example.
• Move a couple of tests from expected-failure to expected-success:
they are valid D-Bus well-known names even if they’re a bit weird.

- Stop using a custom thread for listening to kqueue(2) events. Instead
call kevent(2) in non blocking mode in a monitor callback. Under the
hood poll(2) is used to figure out if new events are available.
- Do not use a socketpair with a custom protocol requiring 2 supplementary
context switches per event to commicate between multiple threads. Calling
kevent(2), in non blocking mode, to add/remove events is fine from any
context.
- Add kqueue(2) events without the EV_ONESHOT flag. This removes a race
where some notifications were lost because events had to be re-added for
every new notification.
- Get rid of the global hash table and its associated lock and races. Use
the 'cookie' argument of kevent(2) to pass the associated descriptor when
registering an event.
- Fix _kh_file_appeared_cb() by properly passing a monitor instead of a
source to g_file_monitor_emit_event().
- Properly refcount sources.
- Remove a lot of abstraction making it harder to fix the remaining issues.
