[dependabot]

Bumps grpc-bom from 1.21.1 to 1.42.0.

Release notes

Sourced from grpc-bom's releases.

v1.41.0

API Changes

• stub: Mark Stub-based MetadataUtils methods deprecated (#8395). The interceptor-based versions have been stable for a long time and are preferred

Bug Fixes

• census: Fixed a data race in CensusStatsModule which in rare cases may cause NullPointerException (#8459)
• xds: Fixed a bug in SharedCallCounterMap which in rare cases may cause NullPointerException (#8397)
• core: ServerCall.isCancelled() and ServerCallStreamObserver.isCancelled() implementations no longer incorrectly return true at the end of every RPC (#8408)
• core: ManagedChannel no longer immediately exits idle mode after an enterIdle() call when it has any calls in progress
• netty-shaded: Modify the shading operation to transform native-image resources so they correctly reference shaded class names (#7540)
• netty-shaded: Rename native-image resources to avoid collisions with Netty’s copy, which were modified starting in 1.39.0
• rls: avoid NullPointerException in RLS in certain circumstances when calling channel.getState(true) or if a parent load balancer requests a connection (#8379)

New Features

• xds: xDS-based TLS security (gRFC 29) is now stable
• util: Added new classes AdvancedTlsX509TrustManager and AdvancedTlsX509KeyManager, which support reloading keys and trust roots as they change. They also can make custom verification easier by handling the hostname verification. (#8175)
• xds: Added XdsNameResolverProvider.createForTest() to allow using a different bootstrap configuration in tests (#8358)

Behavior Changes

• rls: migrated the deprecated server and path fields in RouteLookupRequest to using the new extra_keys field in RLS config

Improvements

• api: Document that NameResolvers shouldn’t block within their methods (#8398). The offload executor should be used for blocking operations
• stub: Document StreamObserver is an async API, and how it internally may buffer (#8449)

Dependencies

• Upgraded error_prone_annotations to 2.9.0
• cronet: Cronet upgraded to version 92.4515.131

v1.40.1

Bug Fixes

• xds: fixed channel panic with NullPointerException if a cluster is configured with RING_HASH LB policy.

v1.40.0

API Changes

• api: Removed deprecated method ClientStreamTracer.Factory.newClientStreamTracer(CallOptions callOptions, Metadata headers).
• api: Deprecated ClientStreamTracer.StreamInfo.getTransportAttrs() and ClientStreamTracer.StreamInfo.Builder.setTransportAttrs().
• api: Added new method ClientStreamTracer.streamCreated(Attributes transportAttrs, Metadata headers).
• core: Stabilized ManagedChannelBuilder.enableRetry() and ManagedChannelBuilder.disableRetry().

Bug Fixes

• core: Fix a flow control issue if retry is enabled (#8401).
• core: Fix a race between client call cancel() and start() if retry is enabled (#8386).
• xds: Fix the race condition in SslContextProviderSupplier's updateSslContext and close (#8294).
• xds: If “server_listener_resource_name_template” is not set or xds_v3 is not in use, log an error and fail XdsServer start() instead of NPE.
• netty: The Netty server produces plain-text error messages for non-gRPC clients. The error pages’ Content-Type incorrectly had encoding=utf-8. It now has charset=utf-8.

New Features

• compiler: Added GrpcGenerated annotation with CLASS retention to the top-level generated class. This can be used by annotation processors to detect or ignore the generated code.
