Release Notes

grpc/grpc-java

v1.29.0

Compare Source

Behavioral Changes

• core, grpclb: change policy selection strategy for Grpclb policy (move logic of querying SRV into Grpclb's own resolver) (#​6723). System property io.grpc.internal.DnsNameResolverProvider.enable_grpclb is eliminated, grpc-grpclb dependency implicitly enables querying SRV records since v1.24.2

New Features

• core: ServerInterceptors.useInputStreamMessages() now preserves the KnownLength interface when wrapping InputStream (#​6852). This should prevent certain optimizations from being disabled when using useInputStreamMessages
• core: ServerInterceptors.useInputStreamMessages() and useMarshalledMessages() now preserve the SchemaDescriptor, so the methods are now compatible with the reflection service (#​6851)

Bug Fixes

• core: Fix IllegalStateException if remote-specified decompressor is unknown (#​6864)
• core: keep round_robin lb subchannel in TRANSIENT_FAILURE until becoming READY (#​6657). This avoids RPC being indefinitely queued when subchannels are bouncing back and forth between CONNECTING and TRANSIENT_FAILURE
• netty: fixed a bug when grpc-netty and grpc-netty-shaded were both used, which could result in "ClassCastException: io.netty.util.AsciiString cannot be cast to io.grpc.netty.shaded.io.netty.util.AsciiString" (#​6765)
• netty: Prevent thread interruption during server start from ing socket (#​6867)
• okhttp: fix incorrect connection-level flow control handling at beginning of connection (#​6742). This only impacted users of OkHttpChannelBuilder.flowControlWindow(), who seem to be few since this bug was not reported sooner
• core: A Java 9+ ABI compatibility issue with java.nio.ByteBuffer is fixed (#​6839). This only impacted users manually compiling grpc-java with JDK 9+ and then using it as a library for applications that run with JDK 8- (e.g., on Android). This does not impact the pre-built JARs on Maven Central
• core: fixed a bug in health check config propagation. (#​6804)
• benchmarks: some netty benchmarks failed to start and are now fixed (#​6877). This was a regression introduced in v1.23.0

Documentation

• Add Javadoc for grpc-services and grpc-grpclb to the grpc-all project. This increases the number of classes shown at https://grpc.io/grpc-java/javadoc/
• examples: Add a JWT authentication example (#​5915)

Dependencies

• Bump guava to 28.2-android (#​6772)
• Bump netty to 4.1.48.Final, bump tcnative to 2.0.30.Final (#​6845)
• Bump truth version to 1.0.1 (#​6754)

Compiling

• android: add grpc-android into main build (#​6793). Compiling with -PskipAndroid=false (default) includes building grpc-android module, which requires Android SDK
