`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
\# GLib-GIO-DEBUG: IPv4 DNS error: IPv4 Broken
(/var/tmp/gitlab_runner/builds/Ff4WDDRj/0/GNOME/glib/_build/gio/tests/network-address:18428): GLib-GIO-DEBUG: 09:03:08.587: IPv4 DNS error: IPv4 Broken
Bail out! GLib-GIO:ERROR:../gio/tests/network-address.c:586:got_addr: assertion failed (error == NULL): IPv4 Broken (g-io-error-quark, 24)
stderr:
**
GLib-GIO:ERROR:../gio/tests/network-address.c:586:got_addr: assertion failed (error == NULL): IPv4 Broken (g-io-error-quark, 24)
```
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
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.
