Release Notes

grpc/grpc-java (io.grpc:grpc-context)

v1.68.2

Compare Source

Bug Fixes

• api: When forwarding from Listener onAddresses to Listener2 continue to use onResult (https://github.com/grpc/grpc-java/pull/11688). This fixes a 1.68.1 "IllegalStateException: Not called from the SynchronizationContext" regression (#​11662) that could be seen in certain custom NameResolvers
• okhttp: If the frame handler thread is null do not schedule it on the executor (https://github.com/grpc/grpc-java/pull/11716). This fixes a 1.68.1 NullPointerException regression when a custom transportExecutor was provided to the channel and it did not have enough threads to run new tasks

Improvements

• examples: Use xds-enabled server and xds credentials in example-gcp-csm-observability (https://github.com/grpc/grpc-java/pull/11707)

gRPC Java 1.68.1 Release Notes

v1.68.0 was a mistake. This is the first release of version 1.68.x

Bug Fixes

• xds: Fix NullPointerException introduced in "Fix load reporting when pick first is used for locality-routing" (#​11553). This was in 1.67.1 but not 1.68.0

Behavior Changes

• core: JSON parsing rejects duplicate keys in objects (#​11575) (4be69e3). This is the existing behavior in C core. Duplicate keys in objects are dangerous as which value takes effect is undefined. Previously, the last value was used
• okhttp: Detect transport executors with no remaining threads (#​11503) (3a6be9c). The transport uses two threads, but one is on-demand. If the executor provided to builder.transportExecutor() runs out of threads (e.g., it is a fixed-size thread pool), all transports can be wedged, unable to run on-demand tasks, until keepalive kills one of them. Two threads are now used when handshaking a new transport, and the transport will time out after 1 second with “Timed out waiting for second handshake thread” if two threads are unavailable
• gcp-csm-o11y: Get mesh_id value from CSM_MESH_ID environment variable, instead of getting it from bootstrap file (84d30af)

Improvements

• New grpc-context-override-opentelemetry artifact (#​11523) (782a44a) (#​11599) (e59ae5f). This is a io.grpc.Context storage override to store its state in io.opentelemetry.context.Context. Libraries should not add a dependency on this artifact, as applications can only have one storage override in their classpath
• New grpc-s2a artifact. It is a transport that offloads the handshake similar to ALTS, but for TLS. It provides io.grpc.s2a.S2AChannelCredentials
• api: Enhance name resolver `ResolutionResult` to hold addresses or error so the single listener API onResult2 is used to convey both success and error cases for name resolution (#​11330) (1ded8af)
• core: Handle NameResolver/LoadBalancer exceptions when panicking (b692b9d). This expands the class of bugs that will fail RPCs with the panic error, versus some undefined behavior
• core: Use the default service config in case of initial name resolver address resolution error (#​11577) (fa26a8b)
• core: StreamTracer.inboundMessageRead() now reports uncompressed message size when the message does not need compression (#​11598) (2aae68e). Previously it always reported -1 (unknown)
• netty: Avoid TCP_USER_TIMEOUT warning when explicitly specifying a non-epoll channel type to use (#​11564) (62f4098)
• okhttp: Don't warn about missing Conscrypt (6f35422). This is especially helpful when using TLS but not running on Android
• android: For UdsChannelBuilder, use fake IP instead of localhost (a908b5e). This avoids an unnecessary DNS lookup
• xds: Add xDS node ID in select control plane errors to enable cross-referencing with control plane logs when debugging (f3cf7c3)
• xds: Enhanced how ADS stream terminations are handled, specifically addressing cases where a response has or hasn't been received (#​2e9c3e19f)
• binder: Update status code documentation for Android 11's package visibility rules. (#​11551) (99be6e9)
• binder: Update binderDied() error description to spell out the possibilities for those unfamiliar with Android internals. (#​11628) (46c1b38)
• example-gauth: Use application default creds instead of file argument (#​11595) (94a0a0d)
• opentelemetry: Experimental OpenTelemetry tracing is available. Set the GRPC_EXPERIMENTAL_ENABLE_OTEL_TRACING environment variable to true to enable tracing support in GrpcOpenTelemetry (#​11409, #​11477)(043ba55, 421e237)

Dependencies

• Updated protobuf-java to 3.25.5. This helps avoid CVE-2024-7254 (2ff837a)

v1.68.0: MISTAKE

Compare Source

This was supposed to be v1.67.0, but there was a mistake during the release process. This has everything in v1.67.1, except for:

• xds: Fix NullPointerException introduced in "Fix load reporting when pick first is used for locality-routing" (https://github.com/grpc/grpc-java/pull/11553)

v1.67.1

gRPC Java 1.67.1 Release Notes

There was no 1.67.0 release. There was a problem making the release and it went to Maven Central as 1.68.0 instead. This is a version-corrected release.

Improvements

• Petiole load balancing policies (e.g., round_robin, weighted_round_robin, ring_hash, least_request) had internal refactorings. This should not have changed their behavior
• api: Introduce onResult2 in NameResolver Listener2 that returns Status (90d0fab)
• core: touch() buffer when detach()ing (e821d5e). This makes it clearer whether a leak is a gRPC leak or an application leak when the Detachable API is being used
• example: delete duplicate and unused code in KeepAliveClient.java (6a9bc3b)
• example: Added Dualstack example (#​11451) (72a977b)
• stub: Add newAttachMetadataServerInterceptor() MetadataUtil (#​11458) (6dbd1b9)
• xds: Separate xds clients for each channel target, each with its own connection to an xds server. (#​11484) (d034a56)
• xds: Envoy proto sync to 2024-07-06 (#​11401) (96a788a)
• xds: cncf/xds proto sync to 2024-07-24 (#​11417) (0017c98)
• xds: Import RLQS protos (#​11418) (c29763d)
• xds: ClusterManagerLB must update child configuration (10d6002). Previously, RLS configuration would not have been updated

Bug Fixes

• core: Revert "Enable new PickFirst LB (#​11348)" (#​11425) (cc1cbe9)
• rls: Fix log statements incorrectly referring to "LRS" (#​11497) (c63e354)
• util: Stop using SocketAddress.toString() for checking address equality (f866c80). This change applies to all petiole load balancing policies. For regular usages that use dns name resolution, this is unlikely to matter as the default dns name resolver returns consistent addresses. But this might improve LB behavior for some custom load balancers
• xds: Fix load reporting when pick first is used for locality-routing. (#​11495) (1dae144)
• xds: Fix NullPointerException introduced in "Fix load reporting when pick first is used for locality-routing" (#​11553). This change is not present in 1.68.0
• xds: XdsClient should unsubscribe on last resource (#​11264) (448ec4f)

Dependencies

• Upgrade Netty to 4.1.110 and tcnative to 2.0.65 (#​11444) (70ae832)
• examples: Upgrade Maven plugin versions (75012a5)
• Remove direct dependency on j2objc (ff8e413)
