Sourced from io.grpc:grpc-okhttp's releases.

v1.74.0

Behavior Changes

• compiler: Default to @generated=omit (f8700a13a). This omits javax.annotation.Generated from the generated code and makes the org.apache.tomcat:annotations-api compile-only dependency unnecessary (README and examples changes forthcoming; we delayed those changes until the release landed). You can use the option @generated=javax for the previous behavior, but please also file an issue so we can develop alternatives
• compiler: generate blocking v2 unary calls that throw StatusException (#12126) (a16d65591). Previously, the new blocking stub API was identical to the older blocking stub for unary RPCs and used the unchecked StatusRuntimeException. However, feedback demonstrated it was confusing to mix that with the checked StatusException in BlockingClientCall. Now the new blocking stub uses StatusException throughout. grpc-java continues to support the old generated code, but the version of protoc-gen-grpc-java will dictate which API you see. If you support multiple generated code versions, you can use the older blocking v1 stub for unary RPCs

Bug Fixes

• netty: Fix a race that caused RPCs to hang on start when a GOAWAY was received while the RPCs’ headers were being written to the OS (b04c673fd, 15c757398). This was a very old race, not a recent regression. All streams should now properly fail instead of hanging, although in some cases they may be transparently retried
• util: OutlierDetection should use nanoTime, not currentTimeMillis (#12110) (1c4309899). Previously, changes in the wall time would impact its accounting
• xds: Don't allow hostnames in address field in EDS (#12123) (482dc5c1c). Only IP addresses were handled properly, and only IP addresses should be handled per gRFC A27
• xds: In resource handling, call onError() for RDS and EDS NACKs (#12122) (efe9ccc22). Previously the resource was NACKed, but gRPC would continue waiting for the resource until a timeout was reached and claim the control plane didn’t send the resource. Now it will fail quickly with an informative error
• xds: Implement equals in RingHashConfig (a5eaa66cc). Previously all configuration refreshes were considered a new config, which had the potential for causing unexpected inefficiency problems. This was noticed by new code for gRFC A74 xDS Config Tears that is not yet enabled, so there are no known problems that this caused
• LBs should avoid calling LBs after lb.shutdown() (1df2a3305). This fixed pick_first and ring_hash behavior that could cause rare and “random” races in parent load balancers like a NullPointerException in ClusterImplLoadBalancer.createSubchannel(), which had a ring_hash child. This is most likely to help xDS, as it heavily uses hierarchical LB policies

Improvements

• util: Deliver addresses in a random order to shuffle connection creation ordering (f07eb47ca). Previously, connections were created in-order (but non-blocking), so in a fast network the first address could be more likely to connect first given a "microsecond" headstart. That first connection then receives all the buffered RPCs, which could cause temporary, but repeated, load imbalances of the same backend when all clients receive the same list of addresses in the same order. This has been seen in practice, but it is unclear how often it happens. Shuffling has the potential to improve load distribution of new clients when using round_robin, weighted_round_robin, and least_request, which connect simultaneously to multiple addresses
• core: Use lazy message formatting in checkState (#12144) (26bd0eee4). This avoids the potential of unnecessarily formatting an exception as a string when a subchannel fails to connect
• bazel: Migrate java_grpc_library to use DefaultInfo (#12148) (6f69363d9). This adds compatibility for --incompatible_disable_target_default_provider_fields
• binder: Rationalize @​ThreadSafe-ty inside BinderTransport (#12130) (c20642874)
• binder: Cancel checkAuthorization() request if still pending upon termination (#12167) (30d40a617)

Dependencies

• compiler: Upgrade Protobuf C++ to 22.5 (#11961) (46485c8b6). This is used by the pre-built protoc-gen-grpc-java plugin on Maven Central. This should have no visible benefit, but gets us closer to upgrading to Protobuf 27 which added edition 2023 support
• release: Migrate artifacts publishing changed from legacy OSSRH to Central Portal (#12156) (f99b2aaef). We aren’t aware of any visible changes to the results on Maven Central

V1.73.0

API Changes

xds: Enable least request by default (#12062) core: Delete the long-deprecated GRPC_PROXY_EXP env variable (#11988) (908f9f19c). This was experimental and has been warning when used since v1.8.0. Use the Java-standard -Dhttps.proxyHost and -Dhttps.proxyPort instead api: Remove deprecated SubchannelPicker.requestConnection() (f79ab2f16). This API was replaced by LoadBalancer.requestConnection() in v1.22.0

Bug Fixes

config: prevents global stats config freeze in ConfiguratorRegistry.getConfigurators() (#11991) (d4c46a7f1) xds: XdsDepManager should ignore updates after shutdown (25199e9df). This fixes a source of java.lang.NullPointerException: Cannot invoke "io.grpc.xds.XdsDependencyManager$RdsUpdateSupplier.getRdsUpdate()" because "routeSource" is null regression introduced in v1.72.0

Improvements

xds: listener type validation (#11933) (c8d1e6e39) xds: add the missing xds.authority metric defined in gRFC A78 (#12018) (6cd007d0d)

New Features

xds: float LRU cache across interceptors (#11992) (7a08fdb7f) xds: propagate audience from cluster resource in gcp auth filter. This completes the gRFC A83, implementation of GCP Authentication Filter. (#11972) (84c7713b2) opentelemetry: Implement grpc.lb.backend_service optional label (961945379). This completes the gRFC A89 implementation, which is enabled when requesting the new label
