There’s a kernel bug on the CI machines which is causing this test to
fail all the time and it’s getting my goat.
The test can be re-enabled later (by reverting this commit) when the
kernel on the CI VM host is fixed. I don’t know when that’s going to
happen.

Otherwise if, for whatever reason, the `app` loses its D-Bus name,
`g_application_quit()` is called from `name_was_lost()` before it’s
called from `quit_already()`, and then `quit_already()` does an invalid
read on `app`.
If the name was not meant to be lost at this point in the test, the
subsequent `g_assert_false (name_lost)` will catch that, so this change
shouldn’t cause the test to pass unnecessarily.

In all these cases we don't really care about running the test file,
while building and basic execution it is relevant.
Also they don't support TAP at all.
Meson supports tap protocol results parsing, allowing us to track better
the tests that are running (and the ones that are actually skipped) without
manually parsing the test output.
However this also implies that using the verbose mode for a test doesn't
show its output by default (unless there are failures).
We cannot use `gvisibility_h` for different visibility header files; you
never know when you're going to refer to the variable again, and
projects might end up needing to retrieve the variable contents—like,
for instance, gobject-introspection using glib as a subproject.
I noticed this when running the test on an Arm Morello system where varargs
have bounds. g_variant_new() was trying to read an integer using va_arg(),
but since there was no argument it resulted in a bounds errors there.
On most other architectures this will just read whatever value is contained
in the next argument register and is not something that ASan can detect, so
it never resulted in test failures.
When a cancellable is cancelled when we call g_cancellable_connect we
used to immediately call the provided callback, while this is fine we
actually had race in case the cancellable was about to be reset or in
the middle of a cancellation.
In fact it could happen that when we released the mutex, another thread
could reset the cancellable just before the callback is actually called
and so leading to call it with g_cancellable_cancelled() == FALSE.
So to handle this, make disconnect and reset function to wait for
connection emission to finish, not to break their assumptions.
This can be tested using some "brute-force" tests where multiple threads
are racing to connect and disconnect while others are cancelling and
resetting a cancellable, ensuring that all works as we expect.
This solves problems with validating untrusted inputs from D-Bus, where
invalid numbers of added and removed menu entries, and positions, could
be specified.
Original patch from
https://bugzilla.gnome.org/show_bug.cgi?id=728733#c7, tweaked by Philip
Withnall to add a few code comments and make
`G_MENU_EXPORTER_MAX_SECTION_SIZE` public so callers can check their
inputs against it if they want. Also tweaked to use `g_warning()` instead
of the nonexistent `g_dbus_warning()`.
Fixes: #861
If it takes one more `GMainContext` cycle than expected for the
`activate` signals to be handled, the `GApplication` under test can be
released too early, and the test will fail due to not seeing a high
enough value of `n_activations`.
Hopefully avoid that by moving the release to a low priority idle
callback.
This fix is only hopeful because I’ve only been able to reproduce the
failure on FreeBSD CI and not locally.

The timeout is just to stop the test hanging forever, so there’s no need
for it to be so short. It’s caused at least one spurious CI failure:

GDesktopAppInfo never failed in the most simple of the cases: when a
desktop file or a command line app info was pointing to an invalid
executable (for the context).
The reason for this is that we're launching all the programs using
gio-launch-desktop which will always exist in a sane GLib installation,
and thus our call to execvp won't ever fail on failure.
This was partially mitigated by not allowing to create a desktop app
icon using a non-existent executable (even if not fully correctly) but
still did not work in case a custom PATH was provided in the launch
context.
To avoid this, use g_find_program_for_path() to find early if a program
that we're about to launch is available, and if it's not the case return
the same error that g_spawn_async_with_fds() would throw in such cases.
While this is slowing a bit our preparation phase, would avoid to leave
to the exec function the job to find where our program is.
Add tests simulating this behavior.
We used to launch applications with terminals using the normal program
finder logic that did not consider the context path nor the desktop file
working dir. Switch to g_find_program_for_path() to find terminals so we
can ensure that both conditions are true.
Update tests to consider this case too.
The platform data comes from the parent process, which should normally
be considered trusted (if we don’t trust it, it can do all sorts of
other things to mess this process up, such as setting
`LD_LIBRARY_PATH`).
However, it can also come from any process which calls `CommandLine`
over D-Bus, so always has to be able to handle untrusted input. In
particular, `v`-typed `GVariant`s must always have their dynamic type
validated before having values of a static type retrieved from them.

These actions are activated as a result of receiving the `ActionInvoked`
signal from `org.freedesktop.Notifications`. As that’s received from
another process over D-Bus, it’s feasible that it could be malformed.
Without validating the action and its parameter, assertions will be hit
within the `GAction` code.
While we should be able to trust whatever process owns
`org.freedesktop.Notifications`, it’s possible that’s not the case, so
best validate what we receive.

As with the previous commit, the arguments to `ActivateAction` have to
be validated before being passed to `g_action_group_activate_action()`.
As they come over D-Bus, they are coming from an untrusted source.

The action name, parameter and new state are all controlled by an
external process, so can’t be trusted. Ensure they are validated before
being passed to functions which assert that they are correctly typed and
extant.

Some applications (eg., gnome-photos) really want a large thumbnail,
if one can be created. Simply falling back to a smaller one (probably
created by an old nautilus), without giving the application a chance
to create a bigger thumbnail, is undesirable because they will appear
fuzzy.
Therefore, at separate attribute sets for all the thumbnail sizes
that are supported in the spec: normal/large/x-large/xx-large.
The old attribute will now return by default the biggest available, as
it used to be, but also including the x-large and xx-large cases.

Do not search in path for snapctl to avoid it to be potentially
overridden by changing the PATH env variable.
Still allow testing by using an ifdef to check if we're building for the
test files or not.
Test all the snap cases and the unknown sandbox one.
We need to use different test processes as we initialize the portal
type early enough that it can't be changed later.
