Despite the name, the call was still doing blocking operations when
looking for app handlers via GAppInfo. Now it's possible to use fully
async calls.
Together with previous commit, the API is now fully async.
Despite the name, we still used blocking calls to get the default app
for URI, now that we have an async implementation of the API to get the
default implementation for URI scheme, we can remove the blocking calls.
We did not check whether this function worked before, so add a simple
test case for it, providing some test functions to make it possible to
reply the same behavior
In some cases (such as in our CI tests) we may not have any dbus session
set after launching, but we always assumed so.
In case we have not a session bus set, we only have to return early.
In both callbacks of g_file_query_default_handler_async() we were
actually using I/O blocking APIs making it not fully async.
Now that such API is provided, we can use it.
While it's possible to create a directory synchronously via
g_dir_make_tmp(), there's no such API that performs it asynchronously.
So implement it using GFile, using a thread to perform such task.
Avoid re defining cases for GIoErrorEnum when we already handle them
through GFileError, so remove code duplication and just rely on
g_file_error_from_errno() to compute the file error and then use
g_io_error_from_file_error() to get the possible IOError.
In case it's something not handled as GFileError, we can use the same
logic as before.
This is now a safe change to do as we have covered all the supported
cases in tests.
The interface was ready for this API but it was not provided.
So implement this, using a thread that calls the sync API for now.
Add tests.

`GSocketClient` chains its internal `GCancellable` objects to ones
provided by the caller in two places using `g_cancellable_connect()`.
However, it never calls `g_cancellable_disconnect()`, instead relying
(incorrectly) on the `GCancellable` provided by the caller being
short-lived.
In the (valid) situation where a caller reuses one `GCancellable` for
multiple socket client calls, or for calls across multiple socket
clients, this will cause the internal `GCancellable` objects from those
`GSocketClient`s to accumulate, with one reference left each (which is
the reference from the `g_cancellable_connect()` closure).
These `GCancellable` instances aren’t technically leaked, as they will
all be freed when the caller’s `GCancellable` is disposed, but they are
no longer useful and there is no bound on the number of them which will
hang around.
For a program doing a lot of socket operations, this still-reachable
memory usage can become significant.
Fix the problem by adding paired `g_cancellable_disconnect()` calls.
It’s not possible to add a unit test as we can’t measure still-reachable
memory growth before the end of a unit test when everything has to be
freed.

g_object_new_with_custom_constructor needs to handle
freezing notifications in the same way as
g_object_new_internal.
Fixing a bug pointed out by Christian Hergert.
The corner-case we are handling here is that
we don't freeze the notify queue in g_object_init
(because there's no custom ->notify vfunc, but
then we gain a notify handler during instance
init, and instance init also triggers a
notification. Handle this by jit freezing
notification in g_object_notify_by_spec_internal.
Note that this is bad code - instance init really
shouldn't be doing things like this.
Testcase included.
Fixes: #2665
We need to match the conditions in g_object_init
for when we already have a freeze. Without that,
we underflow the freeze count and trigger a
warning.
Fixes: #2666
Beef up the singleton testcase to reproduce a
freeze count underflow when setting properties
at construction time, with a custom constructor.

These are deprecated, but it’s easy enough to test them anyway. This
bumps up code coverage a bit and hopefully ensures we don’t accidentally
regress on them in future.

At the moment these tests basically just ensure that the program’s
compiled properly and doesn’t crash on startup. They don’t check
functionality very deeply.
But they’re a start.

This has been documented in `man gobject-query` for a long time, but
seemingly never implemented.
