`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

```
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.

If `GDebugControllerDBus` remains as the only, or default,

`GDebugControllerDBus` requires a `GDBusConnection` at construction

Either we use a default D-Bus connection (but which one? and how would

singleton handling of the `GDebugController` to the user.

On Windows, dbus is launched by spawning the gdbus.exe executable on
demand from the gio module. When linked dynamically, the executable
path is guessed relatively to the gio DLL path. But when linked
statically, the only reference path available is the current
executable path. In this case, gdbus.exe is not necessarily in the same
folder as the current executable.
This patch solves the issue using the same algorithm as the one used
with process spawning in glib core source code two commits above.
This is intended to provide a uniform interface for controlling whether
the debug output from an application (or service) is emitted, typically
to journald, but actually to wherever the application chooses to output
it.
The main implementation of `GDebugController` is `GDebugControllerDBus`,
which is intended to be used on Linux. Other implementations may be
added in future for other platforms, or larger applications may want to
provide their own implementation which integrates with their ecosystem.
The `GDebugControllerDBus` implementation exposes a D-Bus interface at
`/org/gtk/Debugging` with a method to enable or disable debug
output at runtime.
This could be used by external harnesses, such as GNOME Builder or
systemd, to give a uniform way to get debug output from an application.

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.

The gdbus-codegen tool generates documentation from the XML introspection
description of a D-Bus interface. Currently, only DocBook is supported at
the moment, but not every modern documentation generator can handle that
format. The reStructuredText format is a bit more well-supported,
especially in documentation generators for non-C languages.
Unlike DocBook, we get to make our own structure and conventions for how
we structure the documentation when using reStructuredText.
When parsing a comment we're adding <para> elements ourselves, but the
DocBook generator already wraps any block of text that does not start
with a <para> element with one.

While it’s not a supported public part of the API, exporting this

For good measure, run it a third time with no flags at all.
This causes the test to fail if I separately break the fd remapping
implementation. Without this, we fail to test fd remapping on the

Previously, truncated D-Bus messages could cause out-of-bounds reads.
This is a security issue, but one which is only exploitable when

messages). Almost all D-Bus traffic is with a session or system bus,
where the dbus-daemon or dbus-broker is trusted, and is known to have

Since
https://gitlab.gnome.org/GNOME/glib-networking/-/merge_requests/173,
there is now a really surprising implication to using a non-default
GTlsDatabase: your database could do nothing at all other than wrap the
default database, which you would expect to result in no behavior
changes, but in fact it causes fewer security checks to be performed
during certificate verification. This is because certificate
verification moved from GTlsDatabase to GTlsConnection, allowing for
more security checks to be performed. But if using a non-default
GTlsDatabase, we have to fall back to letting GTlsDatabase to the
verification, as before.
This is the best we can do. It's not a regression for applications,
because it means applications get the previous pre-2.72 behavior. But it
does mean that new security checks added in 2.72 are not applied, which
is unfortunate, so we should warn developers about this.
This feature has been reverted for now because I messed up the
implementation and it was doing sync I/O during async API calls. Oops!
Since it's not present in 2.70 nor in 2.72, let's remove the reference
to the exact GLib version that this behavior was introduced in. I'd like
to get it working properly for 2.74, but it's not ready yet and just
changing the version to 2.74 feels optimistic.
Rather than waiting for a fixed period of time, poll in a loop until the
condition the test is expecting is true.
A better solution would be to use a `GSource` and wait until that’s
dispatched. But doing so might affect the behaviour of the
`GInputStream` under test, so busy-wait instead.

around when (as it happens, due to the order of the tests) the
`/gdbus/proxy/no-match-rule` test was run. It would start a second
instance of `gdbus-testserver`, which would exit early due to the test
name still being owned on the bus. The first (killed) instance of
`gdbus-testserver` would then exit, leaving no test servers running, and
hence the new test would fail.
This was being seen as frequent CI failures, particularly on FreeBSD
(must have slightly different timing for process signalling and
termination from Linux).

Once upon a time, we tried to return all possible certificate errors,
but it never actually worked reliably and nowadays we have given up.
This needs to be documented because a reasonable developer would not
expect it.
Because mistakes could be security-critical, I decided to copy the same
warning in several different places rather than relying only on
cross-referencese.
