Sometimes randa and randb end up having the same state, causing them to
return the same stream of 'random numbers'. This is a problem for the
testcase that is looping to find unequal menus.
If we find ourselves in this state, throw one of the random generators
away and recreate it so we have a better chance of getting some unequal
menus.
Give it the same treatment as the exporter for GActionGroup just got.
There is a wart here: the exporter attempt to re-enter GDBusConnection
when it is freed in order to cancel outstanding name watches.
GDBusConnection holds its own lock while calling the destroy notify, so
the attempt at reentrancy results in a deadlock.
We have a workaround to deal with that for now...
Allow the menu to be changed after registration. This is quite useful
for setting up the menus from the ::startup handler instead of having to
do it before registration because it lets you skip the work if you're
not the primary instance.
The error handling on register() was just totally out of hand before.
Clean that mess up.
Take out the menu export for now as well. It will be added back again
later.
Rename g_application_set_menu to g_application_set_app_menu and make a
couple of fixups. Clarify the documentation about exactly what this
menu is meant to be.
Add g_application_set_menubar and document that as well.
This is an interface to represent GSimpleActionGroup-like objects (ie:
those GActionGroups that operate by containing a number of named GAction
instances).
Create a 'mirror' model of the proxy for the testcase. In addition to
testing that the proxy model emits the proper signals this also keeps
the proxy alive (by holding references to it from the mirror).
The previous code would create the submenu proxies and destroy them
right away (from the recursive step in the equality comparison
functions). This means that the subscription would go out over D-Bus
and the proxy would be destroyed before it returned. Keeping the model
alive allows it to be actually updated.
Only resolve the link at the point that we pull it through the API
rather than at the point that we first are told about it. This reduces
the lifespan of subscriptions and, more importantly, avoids a tricky
reference cycle issue.
Each test needs to remove the sources that it attaches
to the default main context, or else things will work
fine in isolation, but go bad in a full test run.
The code assumes in various places that ':' does not occur
in attribute names. We are a little more strict than that,
and only allow lowercase ASCII, digits and '-'.
