"controllee_map_.empty() && !options.include_uncontrolled" seems correct.

[kinuko, 2015/03/20 08:19:39]

Done.

This is how we need tests for every code...

[nhiroki, 2015/03/16 06:37:58]

We might need to check host->provider_type() and to exclude a host whose type is
SERVICE_WORKER_PROVIDER_FOR_CONTROLLER??

[kinuko, 2015/03/20 08:19:39]

That's a good point, hmm yes it looks like. I changed the method to get client
provider hosts and named it 'GetClientProviderHostIterator'.
