This builds out infrastructure to fetch updated PeekInfo structs from
RingRTC on a GroupCallUpdate. There are still a bunch of TODOs to
resolve once RingRTC adds PeekInfo.
Add nickname support. 1:1 threads are now named using the nickname of the contact if available. I expect there'll be design input about how to present this. For now I've gone with putting quotes around the nickname. Also, there's a lot of contact stuff so I'd appreciate checking that I did the correct thing here.
- Removes ContactsUpdater singleton. It wasn't really tracking much
state anyway
- Introduces ContactDiscoveryTask. This creates a
ContactDiscoveryOperation (modern or legacy) and updates the
SignalRecipients database on completion. Returns a promise.
- Begin migrating away from operation queues
PromiseKit is weird about priority propogation, so this shouldn't be
used yet. Since all then closures are asynced, priorities don't
propogate down to underlying queues. This means the a
ContactDiscoveryTask on the main queue will not boost the priority on
the ModernContactDiscoverOperation's owned operation queue
Creates a new root singleton: OWSMessagePipelineSupervisor
As of right now, this singleton has two responsibilities:
- Track all message processing pipeline stages that have registered
themselves
- Post processing suspension updates to interested stages
Four classes will now register themselves as pipeline stages:
- OWSMessageContentQueue
- YAPDBMessageDecryptQueue
- IncomingGroupsV2MessageQueue
- SSKMessageDecryptJobQueue
At initialization, OWSMessagePipelineSupervisor will take out a pipeline
suspension while it waits for a UUIDBackfillTask to complete. Other
interested objects are also able to suspend the message processing
pipeline by invoking suspendMessageProcessing(for:) on the supervisor
(though, currently this is not used by anything except tests)
This also adds some supporting improvements to UnfairLock. Now,
UnfairLock closures will return the value returned from its critical
section closure.
- Removed static UUIDBackfillTask initializer and removed the
registration from AppDelegate. Kicking off the task will be handled
with IOS-631.
- Moved the async perform work to its own function
- Some minor syntactic changes
- Updated database fetch to retrieve empty string UUIDs
- Handles non-e164 numbers fetched from database
- Leverages the MockSSKEnvironment to deal with the shared
SignalServiceAddressCache. Removes added test support.
- Add tests to exercise new functionality
