Java 9 introduces overridden methods with covariant return types for the following methods in java.nio.ByteBuffer:
- position(int newPosition)
- limit(int newLimit)
- flip()
- clear()
- mark()
- reset()
- rewind()
In Java 9 they all now return ByteBuffer, whereas the methods they override return Buffer, resulting in exceptions like this when executing on Java 8 and lower:
java.lang.NoSuchMethodError: java.nio.ByteBuffer.limit(I)Ljava/nio/ByteBuffer
This is because the generated byte code includes the static return type of the method, which is not found on Java 8 and lower because the overloaded methods with covariant return types don't exist (the issue appears even with source and target 8 or lower in compilation parameters).
The solution is to cast ByteBuffer instances to Buffer before calling the method.
This provides a substantial ~3x performance increase to Netty async
streaming with small messages. It also increases OkHttp performance for
the same benchmark 40% and decreases unary latency by 3µs for Netty and
10µs for OkHttp.
We avoid calling listener after closure because the Executor used for
RPC callbacks may no longer be available. This issue was already
present in the ApplicationThreadDeframer, but full-stream compression is
not really deployed so was unnoticed.
DirectExecutor saw a 5-6µs latency increase via MigratingDeframer.
DirectExecutor usages should see no benefit from MigratingDeframer, so
disable it in that case.
- Use gradle configuration `api` for dependencies that are part of grpc public api signatures.
- Replace deprecated gradle configurations `compile`, `testCompile`, `runtime` and `testRuntime`.
- With minimal change in dependencies: If we need dep X and Y to compile our code, and if X transitively depends on Y, then our build would still pass even if we only include X as `compile`/`implementation` dependency for our project. Ideally we should include both X and Y explicitly as `implementation` dependency for our project, but in this PR we don't add the missing Y if it is previously missing.
This change adds two booleans to the ChannelBuilders to
allow transports to use get and put. These are currently defaulted to
on, but unset on the method descriptors. This change is 1/2 that will
allow the safe / idempotent bits to be set on generated proto code.
Part 2/2 will actually enable it.
The use case for this is for interceptors that implement caching logic.
They need to be able to access the safe/idempotent bits on the MD in
order to decide to how to handle the request, even if gRPC doesn't use
GET / PUT HTTP methods.
* cronet: update README for using published grpc-cronet with play service Cronet implementation.
* doc: Added cronet/README.md version update to RELEASING.md.
* Added publish configurations in build file.
* Changed cronet dependency to cronet-api for implementation, only use full cronet implementation provider for testing.
* Set minSdkVersion to 16 as cronet dependency requires that.
* Added errorprone plugin.
* Use reflection to load and invoke setTrafficStats* and addRequestAnnotation methods for ExperimentalBidirectionalStream.Builder.
* Load reflection method lazily and cache for later usages.
The former is deprecated and replaced by the latter in Mockito 2.
However, there is a functional difference: ArgumentMatchers will reject
`null` and check the type if the matcher specified a type (e.g.
`any(Class)` or `anyInt()`). `any()` will remain to accept anything.
