On OSX both backends are built. Generally we want to use the cocoa
backend by default and in case it is not supported, i.e because
the application is not using a bundle then we should fallback
to the gtk one.
ostream_flush_cb() was calling flush_data_list_complete() with a single
element list with an item that had already been freed. This was observed
on OpenBSD where memory is overwritten with 0xdf during free():
error=0x0) at ../glib-2.58.3/gio/gdbusprivate.c:1156
1156 g_mutex_lock (&f->mutex);
(gdb) p /x *f
$74 = {mutex = {p = 0xdfdfdfdfdfdfdfdf, i = {0xdfdfdfdf, 0xdfdfdfdf}},
cond = { p = 0xdfdfdfdfdfdfdfdf, i = {0xdfdfdfdf, 0xdfdfdfdf}},
number_to_wait_for = 0xdfdfdfdfdfdfdfdf, error = 0x0}
This happened because the thread freeing the element didn't properly wait
for the asynchronous flush operation to finish.
Gnome's developer docs say: "g_cond_wait() must always be used in a loop"
https://developer.gnome.org/glib/stable/glib-Threads.html#g-cond-wait
It returns a string in the libc locale, which is not necessarily UTF-8.
Convert that to UTF-8 before returning it to the caller.

More mounts can have same mount path, but only the last one is
accessible. Thus we should always return the last matching mount from
g_unix_mount_at() and g_unix_mount_for(). This should also solve
problems with g_file_trash() on automounted filesystems, which are
caused by the recently added mount checks.

instead of using a generic G_IO_ERROR_FAILED error code.
This is in line with what W32 part of the code is doing with WSAENOTSOCK.
This fix will break two tests in libsoup, which were written following
the implementation and thus expect G_IO_ERROR_FAILED when attempting to
do stuff with no-longer-valid socket descriptors.
This reverts commit 80fcb1bc26.
G_DISABLE_DEPRECATED should never be used by anybody, least of all by
GLib. We have deprecation annotations for the compiler, these days, and
they are much better suited than a macro that makes symbols appear and
disappear. The fact that gtk-doc doesn't understand the deprecation
annotations is a limitation of gtk-doc, and it's gtk-doc that ought to be
fixed.
Commit 80fcb1bc broke GStreamer, which disables old API that was
deprecated before the introduction of the deprecation annotations, but
still uses newly deprecated one, and relies on the deprecation
annotations to do their thing. It also broke libsoup, as it uses
GValueArray in its own API.
Just skip the test if the unix transport isn’t supported. This means we
get better compilation coverage, and more explicit TAP output saying
that the test is being skipped on unsupported platforms.

As pointed out by gtk-doc, these are all symbols which have been marked
as deprecated, but which aren’t protected by a deprecation guard. We
can’t use G_DEPRECATED_IN_* for them, as they are all non-function
symbols. Instead, wrap them in #ifndef G_DISABLE_DEPRECATED.
In some cases, we also need to wrap one or two functions which use the
deprecated types in G_DISABLE_DEPRECATED too.

If using the --interface-info-{body,header} options to gdbus-codegen,
and the first interface to be outputted has no methods, but does have
properties or signals, an uninitialised variable would be used for the
property/signal ‘since’ values.
In other situations, the ‘since’ value for a prior method would have
been incorrectly used for the properties/signals.

The test performs implicit autolaunching of a bus
and checks if it is connectible.
In build the test is moved from "only non-windows with have_dbus_daemon"
to "anywhere".
This is intentional: actually it doesn't execute any external
binaries on unix (so doesn't require dbus_daemon)
and now has win32 implementation.
The test has some problems that are not problems of test itself,
but are reasoned by current win32 implementation:
- since the implementation uses global win32 kernel objects
with fixed names not depending on g_get_user_runtime_dir or other context
if preexisting bus running by some other libgio-using application
the test would silently pass.
- since the implementation uses problematic time-based synchronization,
that has a race condition between opening and reading mmaped address,
the test may randomly fail (I'd not seen this in practice).
- since the implementation autolaunched process works for 3 seconds
after last client disconnects, the executed subprocess runs for 3 seconds
after test exit, maybe locking the libgio-2.0-0.dll file for that time.
This is a bit of breaking change:
After this commit the apps relying of win32 dbus autolaunching,
need to install gdbus.exe alongside with libgio-2.0-0.dll.
A new command for gdbus tool is used for running server:
gdbus.exe _win32_run_session_bus
To implement it gdbus.exe uses the same exported function
g_win32_run_session_bus that earlier was used by rundll.
So (private) ABI was not changed.
It runs the bus syncronously, exiting after inactivity timeout -
all exactly like it was runed earlier with the help of rundll32.
While private exported function may have _some_
version compatibility issues between gdbus.exe and libgio-2.0-0.dll
compiling dbus server registration logic directly into gdbus.exe
can lead to _more hidden and more complex_ compatibility issues
since the names and behaviour of syncronization objects
used to publish server address would be required compatible between
gdbus.exe and libgio-2.0-0.dll.
So using "private" exported function to call
looks like more safe behaviour.
gdbus.exe binary was selected for this task since
it has corresponding name and at least for msys2 is shippied
in same package with libgio-2.0-0.dll
turn_off_the_starting_cursor function is also kept as is,
however it is not obvious if it is still needed
(by now I failed reproducing original issue).
Explicit g_warnings added to help with possible
problematic cases for absent or incompatible gdbus.exe
Mainloop is created after successful daemon creation
Before this change the function leaked mainloop on daemon creation fail
nm_conn_to_g_conn already handles UNKNOWN like NONE (returning
G_NETWORK_CONNECTIVITY_LOCAL in both cases). So in sync_properties
we should also set new_connectivity to G_NETWORK_CONNECTIVITY_LOCAL
for both NM_CONNECTIVITY_UNKNOWN and NM_CONNECTIVITY_NONE.
This has the added benefit that when NetworkManager returns the network
connectivity is UNKNOWN, we set network_available to FALSE as it should
be. Previously, there were cases in a laptop with no network access,
that g_network_monitor_get_network_available returned true, which was
wrong and is also fixed with this commit.

Short names were used in win32 implementation to allow launching
on installations where full path to libgio-2.0-0.dll contain spaces.
However, short names are optional on windows: so if they were disabled
that method fails - see issue linked above.
Since rundll32 doesn't support neither spaces, nor quotes in cmdline
this patch changes rundll32 argument to just .\gio-dll-name.dll
and uses the entire path directory containing gio dll as rundll32
current directory.
Added comments informing about potential subtleties discovered during
writing test for gdbusaddress on win32.
There are not known to have real-world user-visible effect,
so by now I'm only adding comments without creating issues.
Commit f975858e86 removed the NULL check in g_cancellable_cancel() by

Implement the approach suggested in
https://gitlab.gnome.org/GNOME/glib/merge_requests/276
1. Try to open O_RDWR. On success, pass that fd
2. If EACCESS => fail the trash op, we "need" read-write to successfully trash it
3. If EISDIR => re-open the fd with O_PATH, and pass that (which will fail on snap,
but verify the dir for flatpaks)
Don’t pollute the build directory with files generated by running the
test.
Note that there are still other tests in the gsettings.c test suite
which use the build directory, but fixing them is a bit more involved
than I have time for right now. This is a step in the right direction.

Synchronize access to cancelled flag of cancellable, which was
previously access without synchronization in g_cancellable_is_cancelled.
Use atomic operations instead of existing global mutex, to avoid
serializing calls to g_cancellable_is_cancelled across all threads.
Ensure that source is attached to the context before it migth be used
from another thread, since otherwise operation on source are
unsynchronized and not thread-safe.
In particular there was a data race between g_source_attach and
g_source_set_ready_time (used from g_file_monitor_source_handle_event).

It’s occasionally possible for the cancellation of the service to happen
before connection_cb() gets scheduled in the other thread. The
locking/unlocking order of mutex_712570 requires:
• test_threaded_712570(): lock mutex
• test_threaded_712570(): start wait loop
• connection_cb(): lock mutex
• test_threaded_socket_service_finalize(): unlock mutex
• test_threaded_712570(): end wait loop
• test_threaded_712570(): unlock mutex
Fix that by quitting the main loop once connection_cb() has been called
(i.e. once the server thread has received the incoming connection
request), rather than just after the client thread (main thread) has
sent a connection request.

On about 1 in 3 test runs, the socket-service would fail with the
ref_count assertion in connection_cb() failing (the ref_count would be 3
rather than the expected 2).
This was happening because the GTask from
g_socket_listener_accept_socket_async() now always takes at least one
main context iteration to return a result (whereas before
6f3d57d2ee it might have taken zero), but
the ref_count can drop below 3 before the process of returning a result
starts. During the process of returning a result, the ref_count
temporarily increases again, which is what was breaking the test.
Fix this by waiting for one more main context iteration. This is a bit
of a hack, but the real fix would be to expose the outstanding_accept
boolean from GSocketService as public API (which the test can
interrogate), and that seems too much like exposing internal state.

GIO modules built with MSVC do not begin with 'lib', but they can
begin with 'gio'. Without this, you can only load GIO modules built
with MSVC that are `name.dll`, not `gioname.dll`.
Compilers get confused when variables are initialized by a function by
taking them as reference in an out argument; this, coupled with the fact
that C does not initialize variables by default, most commonly results
in a "maybe uninitialized" compiler warning.
512e9b3b34 added a call to schedule_pending_close() in the read
callback after the reference to the worker is already gone. In case this was
the last reference to the worker this resulted in a use-after-free.
6f3d57d2ee made this more likely to happen because on connection close
the worker cancel action is now async while the reference to the worker
gets dropped right away.
Move the call to schedule_pending_close() before the unref.

getsockname() returns the address that the socket was bound to.
If it was bound to INADDR_ANY, getsockname() will stubbornly return INADDR_ANY
(and someport - that one is valid).
Subsequent connection attempts to INADDR_ANY:someport will fail with winsock.
Actually, it doesn't make even sense to connect to INADDR_ANY at all
(where is the socket connecting to? To a random interface of the host?),
so this is just a straight-up change, without platform-specific ifdefing.
Use loopback instead of INADDR_ANY. To ensure that binding and creation
of INADDR_ANY is still tested, use two addresses: bind to INADDR_ANY,
but connect to loopback, with the port number that we got from the bound
address.
Use a static GQueue to form the GList of mounts by appending (which
is fast, because GQueue tracks the tail pointer of its internal GList),
then return that GList. This way we don't need to form the list
by prepending, which would have made it necessary to reverse it before
returning.
If the list is not ordered correctly, local drives in GTK places sidebar
are shown in reverse order.
