When no path is provided for the schema, we have call
g_settings_new() instead of g_settings_new_with_path()
passing a NULL path.
This was crashing the tool on start since an assertion was
recently added to g_settings_new_with_path() to refuse NULL.
This allows the caller to specify the reply type that they are expecting
for this call. If the reply comes back with the wrong type, GDBus will
generate an appropriate error internally.
- add a GVariantType * argument to g_dbus_connection_call() and
_call_sync().
- move the internal API for computing message types from introspection
data to be based on GVariantType instead of strings. Update users
of this code.
- have GDBusProxy pass this calculated GVariantType into
g_dbus_connection_call(). Remove the checks done in GDBusProxy.
- Update other users of the code (test cases, gdbus-tool, GSettings
tool, etc). In some cases, remove redundant checks; in some other
cases, we are fixing bugs because no checking was done where it
should have been.
Closes bug #619391.
There is currently no way (near as I can tell) to ensure that a message
has been sent when using GDBus. If we exit() before we are sure, then
it is very possible that the message isn't sent at all. This behaviour
was observed when using the GSettings commandline tool with dconf.
A quick and dirty workaround for now.
