Kun Zhang 7a29f3993c Pass transports instead of futures of transports for new calls. ... This PR finishes the refactoring started by #1395. Resolves #1342. Major changes: - All interfaces that return `ListenableFuture<T>` now return `T` - Stop passing `null` for transports after shut down. Pass `FailingClientTransport` instead. This simplifies the interface semantics of interfaces that return a transport, as well as their callers because they no longer need to check for `null`. - Add two methods to `TransportManager`: - `createInterimTransport()` takes the place of `BlankFutureProvider` in `LoadBalancer` implementations. - `createFailingTransport()` takes the place of errors in the `Future` when `LoadBalancer` implementations propagate errors to the caller. - `createInterimTransport()` creates a `DelayedClientTransport` tracked by `ManagedChannelImpl`, which will not terminate until all `DelayedClientTransport`s, in addition to the `TransportSet`s, are terminated. - Removed the transport argument from the ready and shutdown callbacks, because if `LoadBalancer` was given a delayed transport earlier, it will get the real transport's shutdown event, thus won't be able to match the two through identity comparison, which beats the purpose of passing the transport.		2016-02-23 09:42:03 -08:00
