This patch serie include changes to respond to Eric and Daniel's comments.
The event namespace part of the ID is only handled at the object event's
level, though we need to strip it out of virObjectEventStateEventID to get
the remote driver properly deregister.
Cédric Bosdonnat (7):
Added Network events API and virNetworkEventLifecycle.
test driver: implemented network events
Add network events unit tests
Add network events to the remote driver
Added network events to the bridged network driver
Fixed indentation in src/conf/*_event*
Added default case with error for object event dispatching

Oppps, missed changes to src/remote_protocol-structs which
causes 'make check' to fail - I've added the obvious bits.

Essentially - you need to check for NULL event.

Sure, but the weird thing it that it should also complain on the similar
functions for domain events, right above this one in the same file.

Revisiting this. The problem can only happen on OOM situations, so it's
not that likely to hit in real life; but we should indeed fix our code.
I think the easiest way is to fix remoteDomainEventQueue to gracefully
do nothing on a NULL event (events are best effort, and if OOM occurs,
skipping event delivery is an acceptable action, since we have no way of
reporting the error). I'll post a patch.

Actually, it turns out we are quite lucky - appending a NULL event to
the queue had no ill effects, because when checking for what callbacks
to dispatch, our first use of events was an early exit if
(!virObjectIsClass(event, cb->klass)). So the ATTRIBUTE_NONNULL could
actually be deleted - but that in turn implies we have a lot of code
that checks for non-null events before queueing them up which could also
be simplified. And even if we did that, queueing a NULL event is a
waste of resources compared to just avoiding them altogether.

New subject: [libvirt] [PATCH v4 7/7] Added default case with error for object event dispatching
Hitting this should be pretty rare, but at least developers will know
that they are providing a weird event ID. Otherwise for namespace that
are added in the normal way, gcc will raise a warning about unhandled
case in the switch.
