When running the nonce-tcp and tcp-anonymous tests in one run
of gdbus-peer, or running one of them twice via command-line options
"-p /gdbus/tcp-anonymous -p /gdbus/tcp-anonymous", the one run second
would sometimes fail to connect with ECONNRESET.
Adding more debug messages revealed that in the successful case,
g_main_loop_run() was executed in the server thread first:
# tcp-anonymous: server thread: listening on tcp:host=localhost,port=53517
# tcp-anonymous: server thread: starting server...
# tcp-anonymous: server thread: creating main loop...
# tcp-anonymous: server thread: running main loop...
# tcp-anonymous: main thread: trying tcp:host=localhost,port=53517...
# tcp-anonymous: main thread: waiting for server thread...
but in the failing case, the main thread attempted to connect
before the call to g_main_loop_run() in the server thread:
# tcp-anonymous: server thread: listening on tcp:host=localhost,port=40659
# tcp-anonymous: server thread: starting server...
# tcp-anonymous: server thread: creating main loop...
# tcp-anonymous: main thread: trying tcp:host=localhost,port=40659...
# tcp-anonymous: server thread: running main loop...
(The log message "creating main loop" was immediately before
create_service_loop(), and "running main loop" was immediately
before g_main_loop_run().)
To ensure that the GDBusServer has a chance to start accepting
connections before the main thread tries to connect to it, do not
tell the main thread about the service_loop immediately, but instead
defer it to an idle.

This test originally did not connect to the bus, which meant it was
omitted from commits like 415a8d81 that made sure none of GLib tests
rely on the presence of an existing session bus. (In particular,
Debian autobuilders don't have a session bus.)
When test_double_array() was added, environments like the Debian
autobuilders didn't catch the fact that this test relied on having a
session bus, because it is often skipped in minimal environments
due to its libdbus-1 dependency.
We don't actually need to connect to a dbus-daemon here: it's enough
to convert the message from GVariant to D-Bus serialization, and
back into an in-memory representation through libdbus. That's what
check_serialization() does, and I've verified that when I re-introduce

The gdbus GTask port introduced a deadlock because some code had been
using g_simple_async_result_complete_in_idle() to ensure that the

GTask used a 10-thread thread pool for g_task_run_in_thread() /
g_task_run_in_thread_sync(), but this ran into problems when task
threads blocked waiting for another g_task_run_in_thread_sync()
operation to complete. Previously there was a workaround for this, by
bumping up the thread limit when that case was detected, but deadlocks
could still happen if there were non-GTask threads involved. (Eg, task
A sends a message to thread X and waits for a response, but thread X
needs to complete task B in a thread before returning the response to
task A.)
So, allow GTask's thread pool to be expanded dynamically, by watching
it from the glib worker thread, and growing it (at an
exponentially-decreasing rate) if too much time passes without any
tasks completing. This should solve the deadlocking problems without
causing sudden breakage in apps that assume they can queue huge
numbers of tasks at once without consequences.

For all of the effort spent ensuring that this algorithm would be
correctly threadsafe, I messed up the order of operations within a
single thread when porting to the new approach.
Fix that up.
Also: fix some overzealous asserting in the testcases. Since shutdown
is now lazy, we can never surely say !is_running at any particular point
in time.
This can be used to query whether the task has completed, in the sense
that it has had a result set on it, and has already – or will soon –
invoke its callback function.
Notifications for this property are emitted immediately after the task’s
main callback, in the same main context as that callback. This allows
for multiple bits of code to listen for completion of the GTask, which
opens the door for blocking on cancellation of the GTask and improved
handling of ‘pending’ behaviour.

There was a theoretical deadlock between the worker trying to emit a
signal at the same time as we were waiting for it to shutdown the
notification (while holding the lock).
The deadlock was particularly annoying because we didn't really need to
wait for the shutdown and because it wasn't possible to signals to
arrive while waiting for a start. Attempting to deal with start and
stop in an asymmetric way could have lead to other weird situations,
however.
Drop the lock while waiting for the worker thread to start. This means
that we face the possibility of multiple waiters on the cond at the same
time, so we need to make more of a state machine.

Fix two problems:
1) If g_socket_service_stop is called before the accept call is requeued,
then the reference count won't decrease and this code will hang forever:

g_main_context_iteration (NULL, TRUE);
2) Sometimes the testcase fails (maybe 1 in 200 times for me):
GLib-GIO:ERROR:socket-listener.c:73:connection_cb: assertion failed
(G_OBJECT (service)->ref_count == 2): (3 == 2)

The problem is that depending on ordering, cancellation of the async
listener can require further main context iterations before it releases
the reference on the socket service. Furthermore, in some cases, it
requires at least one iteration.

that too. But the existing name doesn't really make sense for sockets,

GResolver doesn't do full validation of its inputs, so in some of

Redo the code for type-based selection of applications (all,

At the same time, we expand the functionality to add support for the new

- moving ~/.local/share/applications/mimeapps.list to ~/.config/
- per-desktop default applications (via XDG_CURRENT_DESKTOP)
- sysadmin customisation of defaults (via /etc/xdg/mimeapps.list)
- deprecation of the old defaults.list, favouring the use of
/usr/share/applications/mimeapps.list (or gnome-mimeapps.list) to
accomplish the same
We modify the mimeapps testcase to check for mimeapps.list having been
created in XDG_CONFIG_HOME instead of XDG_DATA_HOME.
The modification is a net reduction of code (due to less duplication in
bookkeeping). It is also an increase in performance and reduction in
memory consumption (due to simplified data structures). Finally, it
removes the stat-based timestamp checking in favour of the
GFileMonitor-based approach that was already being used in the
implementation of DesktopFileDir (in order to know if we had to rescan
the desktop files themselves).

It is our intention that memory output streams should operate in two
distinct modes, depending on if a realloc function was provided or not.
In the case that we have a realloc function (resizable mode), we want
the stream to behave as if it were a file that started out empty. In
the case that we don't have a realloc function (fixed-sized mode), we
want the stream to behave as a block device would.
To this end, we introduce two changes in functionality:
- seeking to SEEK_END on a resizable stream will now seek to the end of
the valid data region, not to the end of the allocated memory (which
is really just an implementation detail)
- seeks past the end of the allocated memory size are now permitted,
but only on resizable streams. The next write will grow the buffer
(inserting zeros between).
Some tweaks to testcases were required in order not to break the build,
which indicates that this is an API break, but it seems unlikely that
anyone will be effected by these changes 'in the real world'.
Updates to documentation and further testcases are in following commits.
Based on a patch from Maciej Piechotka <uzytkownik2@gmail.com>.

Over many years of writing code interacting with subprocesses, a pattern
that comes up a lot is to run a child and get its output as UTF-8, to
put inside a JSON document or render in a GtkTextBuffer, etc.
It's very important to validate at the boundaries, and not say deep
inside Pango.
We could do this a bit more efficiently if done in a streaming fashion,
but realistically this should be OK for now.
We weren't closing the streams after we were done reading or writing,
which is kind of essential. The easy way to fix this is to just use
g_output_stream_splice() to a GMemoryOutputStream rather than
hand-rolling it. This results in a substantial reduction of code
complexity.
A second serious issue is that we were marking the task as complete when
the process exits, but that's racy - there could still be data to read
from stdout. Fix this by just refcounting outstanding operations.
This code, not surprisingly, looks a lot like the "multi" test.
Next, because processes output binary data, I'd be forced to annotate
the char*/length pairs as (array) (element-type uint8). But rather than
doing that, it's *far* simpler to just use GBytes.
We need a version of this that actually validates as UTF-8, that will be
in the next patch.
There are a number of nice things this class brings:
0) Has a race-free termination API on all platforms (on UNIX, calls to
kill() and waitpid() are coordinated as not to cause problems).
1) Operates in terms of G{Input,Output}Stream, not file descriptors
2) Standard GIO-style async API for wait() with cancellation
3) Makes some simple cases easy, like synchronously spawning a
process with an argument list
4) Makes hard cases possible, like asynchronously running a process
with stdout/stderr merged, output directly to a file path

Rather than having lots of obscure platform-based #ifdefs all over
gio, define some macros in gcredentialsprivate.h, and use those to
simplify the rest of the code.

Previously, no testcases tested the close flags of
g_output_stream_splice_async. This patch adds tests for that and
also tests various combinations of threaded and non-threaded
GInputStream async reads and GOutputStream async writes.

Make use of __wgetmainargs() on Windows so that we can get wide char
versions of the argv's that are passed in when this test program is being
invoked. This is necessary as one might enter non-ASCII, such as
CJK characters filenames and/or directories to run the test program
against, so that we can process the name(s) and pass the proper
UTF-8-encoded name(s) of the files/directories that is being tested.
