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
This commit puts an additional underscore before the external symbol
`_g_binary_test1_resource_data` when using gcc for Windows, to match
the compiler's expectation.

This tests for #2503. It's fragile, but there is no non-fragile way to
test this. If the test breaks in the future, it will pass without
successfully testing the bug, not fail spuriously, so I think this is
OK.
We should run test_pass_fd twice, once using gspawn's fork/exec codepath
and once attempting to use its posix_spawn() codepath. There's no
guarantee we'll actually get the posix_spawn() codepath, but it works
for now on Linux.
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
posix_spawn() codepath.
Specs say that on Unix id should be desktop file id from the xdg menu
specification, however, currently code just uses basename of .desktop file.
Fix that by finding the .desktop file in all the desktop_file_dirs and use
basename only as a fallback.
See https://specifications.freedesktop.org/menu-spec/latest/go01.html#term-desktop-file-id
and https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s02.html#desktop-file-id
"To determine the ID of a desktop file, make its full path relative to the
$XDG_DATA_DIRS component in which the desktop file is installed, remove the
"applications/" prefix, and turn '/' into '-'."
Also, add unit test that verifies Desktop Id is being correctly set

meson in git master now warns about a missing `check:` kwarg, and may
eventually change the default from false to true.
Take the opportunity to require `objcopy --help` to succeed -- it is
unlikely to fail, but if it does something insane happened.
The code in `g_dbus_message_new_from_blob()` has now been fixed to
correctly error out on all truncated messages, so there’s no need for an
arbitrary programmer error if the input is too short to contain a valid
D-Bus message header.

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.

I could not reproduce the failure remotely with a few hundred
invocations of the test, so it might only present itself on BSD, which
presumably has different socket timing behaviour from Linux.

This was previously done (by commit 63038d1e4c) in one of the cases
where `kill_test_service()` was called — but not the other.
This meant that one instance of `gdbus-testserver` could still be
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).

These are known leaks, as they were being done in tests which were
checking precondition failures.
However, since we know what happens when the failures occur, we can
still free the input data reliably, so do that.
This improves the valgrind output for `actions` to show zero definite
leaks.

The `actions` test previously waited an arbitrary 100ms for various
D-Bus messages to be sent/received, before checking the results of those
messages.
Normally, this would work, but on heavily loaded CI systems, it would
sometimes fail. For example,
https://gitlab.gnome.org/GNOME/glib/-/jobs/1611701.
Fix that by waiting for the condition being checked to evaluate to true,
rather than waiting an arbitrary period of time. On faster machines,
this will speed the tests up too.
Assume that the global default `GMainContext` is in use, so a
`GMainContext*` pointer doesn’t have to be passed around.

D-Bus has an upper limit on number of Match rules and it's rather easy to hit
with a big number of proxies with signal subscriptions. This happens with
NetworkManager with hundreds of devices or connection settings. By passing
G_DBUS_SIGNAL_FLAGS_NO_MATCH_RULE to g_dbus_connection_signal_subscribe(), the
user can call AddMatch with a less granular match instead of a match per every
proxy.
Tests subsequently added by Philip Withnall.

Previously, the delay-apply status of the parent `GSettings` object
would be partially inherited: `settings->priv->backend` in the child
`GSettings` object would point to a `GDelayedSettingsBackend`, but
`settings->priv->delayed` would be `NULL`.
The expectation from https://bugzilla.gnome.org/show_bug.cgi?id=720891
was that `get_child()` would fully inherit delay-apply status.
So, ensure that `settings->priv->delayed` is correctly set to point to
the delayed backend when constructing any `GSettings`. Update the tests
to work again (presumably the inverted test was an oversight in the
original changes).

We were lucky that this worked in some cases (the test is racy), but we
