Besides API changes, this implementation is also up-to-date with the
latest design:
1. Delegate to round-robin and pick-first policies if requested by
the naming system.
2. OOB channels to LoadBalancer always use the LB authority provided by
the naming system.
3. Never send application RPCs to balancer addresses, even if the
address returns UNIMPLEMENTED error.

Instead of `List<List<ResolvedServerInfo>>`, `onUpdate` now takes
`List<ResolvedServerInfoGroup>` as an argument and every `ResolvedServerInfoGroup`
object can have `Attributes` attached to it which means that we can provide
attributes on each level:
* root level via `onUpdate` argument (applies to all servers)
* group level via property of `ResolvedServerInfoGroup` (applies to all servers
in the group)
* host level via property of `ResolvedServerInfo` (applies to a single server)
partially resolving #1469
The added option for java_plugin `enable_deprecated` is `true` by default in `java_plugin.cpp`, so the generated code for `TestService.java` (`compiler/build.gradle` not setting this option) has all deprecated interfaces and static bindService method.
`./build.gradle` and `examples/build.gradle` set this option explicitly to `false`, so all the other generated classes do not have deprecated code.
Will set `enable_deprecated` to `false` by default in future PR when we are ready.
first step to address issue #1469:
- leave and deprecate interfaces in codegen
- introduce `ServiceImplBase`,
- `AbstractService` is deprecated and extends `ServiceImplBase`
- static `bindService()` is deprecated
This allows us to play with zero-copy and proto3 support for lite.
Unfortunately, it introduced some warnings, so deprecated warnings are
now ignored for benchmarks and interop-testing.
This reverts commit 3df1446deb.
The commit was adding to the difficulty of integration for testing. By
itself it isn't bad, so this is a temporary revert until the many other
commits are absorbed and then it will be reapplied.
This does have a manual edit for ClientCallsTest.
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.
Although the changes were determined automatically, they were manually
applied to the codebase.
ClientCalls actually has a bug fix, since the suggestion to add
interrupt() made it obvious that interrupted() was inappropriate.
This reduces the number of classes defined, which reduces memory usage.
It also reduces the number of methods defined, which is important
because of the dex limit.
This should have virtually zero performance degradation because the
contiguous switch uses tableswitch bytecode.
This reverts commit eca1f7c1d6.
We want to preserve the status message identical to what the server
sent. We'll need a better way to communicate debugging details.
- Set knownAcceptEncodingRegistry in SingleTransportChannel
- Change the package name of load_balancer.proto to be consistent with
what is used internally.
