Currently, collection cleanup code is only run when an added event
is received from the server. Where that fails is in scenarios where
a server-side collection turns empty while an affected users is
disconnected - and then reconnects. There's no removed (or updated)
event so no cleanup code is run and you have stale data.
This commit guarantees a stale data check is run whenever a subscription
is established again. The `added` check was also maintained, although
I'm not too sure anymore it's is still needed. That may need to be
revisited.
Move all Etherpad's access control from Meteor to a separated [Node application](https://github.com/bigbluebutton/bbb-pads).
This new app uses [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
to create groups and manage session tokens for users to access them. Each group
represents one distinct pad at the html5 client.
- Removed locked users' access to pads: replaced readOnly pad's access with a new pad's content sharing routine
- Pad's access is now controlled by [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
- Closed captions edited content now reflects at it's live feedback
- Improved closed caption's dictation mode live feedback
- Moved all Etherpad's API control from Meteor to a separated [app](https://github.com/bigbluebutton/bbb-pads)
- Included access control both in akka-apps and bbb-pads
