The g_object_bind_property_with_closures() function should set a
marshaller if the two GClosures don't have one already. This simplifies
the caller code and avoids duplication.
We need to add a new marshaller to the gmarshal.list matching the
signature of the GBindingTransformFunc function.
Spell out "RECEIVED SIGNAL" instead of "SIGNAL" to emphasize this is
about receiving a signal, not emitting one (which is "SIGNAL
EMISSION"). Also make the "arrows" point in the "right" direction
("<<<<" vs ">>>>") - like this:
========================================================================
GDBus-debug:Signal:
<<<< RECEIVED SIGNAL org.freedesktop.DBus.NameOwnerChanged
on object /org/freedesktop/DBus
sent by name org.freedesktop.DBus
and

Commit 5e6f762d61 (introducing UTF-8
validity checks for GVariant instances containing strsings) actually
uncovered a bug in glib-compile-schemas - a GString was passed when a
C string was expected.

As discussed with Ryan on IRC.
This check is crucial because it guarantees that
g_variant_get_string() will _always_ return valid UTF-8. Except in
cases where the programmer used unsafe API such as
g_variant_new_from_data() and setting @trusted to TRUE.
In fact, this check revealed a flaw in my polkit gdbus port
(lt-polkitd:11632): GLib-CRITICAL **: g_variant_new_string: assertion
`g_utf8_validate (string, len, NULL)' failed
and with this I could easily find the problem by using gdb(1) and
G_DBUS=fatal-warnings.
Without this check we'd pass the non-UTF8 string all the way to the
message bus and the bus would then disconnect us. So instead I was
seeing
g_dbus_connection_real_closed: Remote peer vanished with error:
Underlying GIOStream returned 0 bytes on an async read
(g-io-error-quark, 0). Exiting.
and then SIGTERM as raised by g_dbus_connection_real_closed() and my
polkitd process would exit. This behavior is much harder to debug than
failing early (as this patch implements).

This should make things easier to debug:
g_dbus_connection_real_closed: Remote peer vanished with error:
Underlying GIOStream returned 0 bytes on an async read
(g-io-error-quark, 0). Exiting.

the FdSource was calling g_cancellable_disconnect while holding the
main context lock, which is bad news if the ::cancelled handler is
trying to get that lock to wake up the mainloop...
Bug 586432
Since GSettings got the same functionality and flag in commit ca3b7b75b
GBinding should also have the ability to automatically invert a boolean
value without requiring a custom transformation function.
Since using the function pointer version muddles the memory management
requirements of language bindings, we should implement a GClosure-based
variant on top of g_object_bind_property_full().

When binding a boolean setting to a boolean property, invert the values.
This avoids the requirement for writing a pair of mapping functions for
this extremely common case.
Add a test.
