2f171d0ed4 tests: Fix remaining race in gdbus-connection filter test
Commit 721e385 left one remaining race in the filter test, with a
comment associated with it. Unfortunately, the (seemingly unrelated)
changes in #1841 to `GCancellable` seem to have made this remaining race
a lot more likely to fail on FreeBSD than before.

What’s likely to have happened (although I was unable to reproduce the
failure, due to not having a FreeBSD system; I was only able to
reproduce the problem as a 3/1000 failure on Linux, which is still worth
fixing) is that the atomic write of the `FilterData.serial` to be
expected by the filter function sometimes happened after the filter
function had executed, so the expected message was dropped and didn’t
result in an update to the `FilterData` state.

Rework the test so that instead of setting some expectations (on
`FilterData`) in one thread and then checking them in another thread,
the worker thread just unconditionally returns messages from the filter
function to the main thread, and then the main thread checks whether the
expected one has been filtered.

With this change applied, the `gdbus-connection` test passes 5000 times
in a row for me, on Linux; and doesn’t seem to fail any more on the
FreeBSD CI machines over a few runs. (Previously it failed on 4/5 runs.)

721e385593 tests: Use atomics for shared data in gdbus-connection test
D-Bus filter functions run in a worker thread. The `gdbus-connection`
test was sharing a `FilterData` struct between the main thread and the
filter function, which was occasionally (on the order of 0.01% of test
runs) causing spurious test failures due to racing on reads/writes of
`num_handled`.

7e8d4145af gdbus: fix deadlock on message cancel/timeout
The gdbus GTask port introduced a deadlock because some code had been
using g_simple_async_result_complete_in_idle() to ensure that the
callback didn't run until after a mutex was unlocked, but in the gtask
version, the callback was being run immediately. Fix it to drop the
mutex before calling g_task_return*(). Also, tweak
tests/gdbus-connection to test this.

f7abd3ce13 Add g_spawn_check_exit_status()
Many (if not "almost all") programs that spawn other programs via
g_spawn_sync() or the like simply want to check whether or not the
child exited successfully, but doing so requires use of
platform-specific functionality and there's actually a fair amount of
boilerplate involved.

This new API will help drain a *lot* of mostly duplicated code in
GNOME, from gnome-session to gdm.  And we can see that some bits even
inside GLib were doing it wrong; for example checking the exit status
on Unix, but ignoring it on Windows.

f07201c314 GDBusConnection: Fix race in /gdbus/connection/life-cycle
GDBusConnection sets the closed flag in the worker thread, then adds an
idle callback (which refs the Connection) to signal this in the main
thread. The tests session_bus_down doesn't spin the mainloop, so the
"closed" signal will always fire if iterating the mainloop later (and
drops the ref when doing so). But _is_closed can return TRUE even before
signalling this, in which case the "closed" signal isn't fired and the
ref isn't dropped, causing the test to fail.

Instead simply always wait for the closed signal, which is a good thing
to check anyway and ensures the ref is closed.

f0b04acfd3 GDBusConnection: Avoid callbacks on finalized connection
Turns out that GDBusWorker will issue callbacks (in its own thread)
even after g_dbus_worker_stop() has been called. This would rarely
happen (and unreffing a connection is even rarer) so only saw this bug
occasionally when running the gdbus-connection test case in a loop.

Fix up this issue by maintaining a set of GDBusConnection objects that
are currently "alive" and do nothing in the callbacks if the passed
user_data pointer is not in this set.

Also attempted to fix up a race condition with
_g_object_wait_for_single_ref_do() and its use of GObject toggle
references - for now, just resort to busy waiting, thereby
sidestepping the toggle reference mess altogether.

8a3a4596e2 Bug 626748 – Use async methods for writing and handle EAGAIN
If sending a lot of data and/or the other peer is not reading it, then
socket buffers can overflow. This is communicated from the kernel by
returning EAGAIN. In GIO, it is modelled by g_output_stream_write()
and g_socket_send_message() returning G_IO_ERROR_WOULD_BLOCK.

It is also problematic that that we're using synchronous IO in the
shared GDBus IO thread. It means that one GDBusConnection can lock up
others.

It turns out that by porting from g_output_stream_write() to
g_output_stream_write_async() we fix the EAGAIN issue. For GSocket, we
still need to handle things manually (by creating a GSource) as
g_socket_send_message() is used.

We check the new behavior in Michael's producer/consumer test case (at
/gdbus/overflow in gdbus-peer.c) added in the last commit.

Also add a test case that sends and receives a 20 MiB message.

Also add a new `transport' G_DBUS_DEBUG option so it is easy to
inspect partial writes:

 $ G_DBUS_DEBUG=transport ./gdbus-connection -p /gdbus/connection/large_message

d2d97a214d Bug 625584 – Crashes application on unref with signal subscription
Don't do too much work in the finalizer - in particular, there's no
need to send RemoveMatch() messages to the bus daemon since we're
going to sever the connection and the bus will garbage collect
anyway. In this case it crashed the process.

Also add a test case that checks that the appropriate GDestroyNotify
callbacks are called when unreffing a connection with either 1)
exported objects; 2) signal subscriptions or 3) filter functions
.. yes, ideally apps would unregister such callbacks before giving up
their ref but that's not how things work :-)

0b2b4deac5 GDBus: Add GDBusSendMessageFlags
This is currently unused but might be useful in the future. For
example, it might be nice with a way to bypass the current queue of
outgoing messages - having a flag enumeration allows us to add a
G_DBUS_SEND_MESSAGE_FLAGS_BYPASS_QUEUE etc. etc.

This commit breaks ABI and API. Users of the (rarely used) API to send
messages will have to port to this new API.

4a1c5a1b98 GDBus: Add GDBusSignalFlags and use it in g_dbus_connection_signal_subscribe()
This is currently unused but will probably be useful in the
future. For example, we could have a _ARG0_IS_PATH to specify that
arg0 should be used for arg0path.

This commit breaks API and ABI. Users of
g_dbus_connection_signal_subscribe() will need to port to this new
version.

914b046226 GDBusConnection: Fix up g_dbus_connection_close()
... so it is async, cancelable and returns an error. Also provide a
synchronous version.

This is an API/ABI break but it is expected that only very few
applications use this API.
