v1.72.0

Compare Source

API Changes

• util: Remove deprecated method GracefulSwitchLb.switchTo() (f207be3). It is rarely used outside of gRPC itself. The configuration is passed as lb policy configuration instead
• xds: Add support for custom per-target credentials on the transport (#​11951) (1958e42)
• xds: Explicitly set request hash key for the ring hash LB policy (892144d)

Bug Fixes

• core: Apply ManagedChannelImpl's updateBalancingState() immediately (ca4819a)
• xds: Fix cluster selection races when updating config selector (d82613a)
• otel: Fix span names as per the A72 gRFC changes (#​11974) (94f8e93)
• xds: ClusterResolverLoadBalancer handle update for both resolved addresses and errors via ResolutionResult (#​11997) (8681786)

Improvements

• netty: Avoid allocating an exception on transport shutdown. This reduces allocation rate for connection-heavy workloads/load testing (a57c14a)
• servlet: Set an explicit description for CANCELLED status (#​11927) (fca1d3c)
• xds: gRFC A74 xDS Config Tears implementation in the XdsNameResolver (e80c197). While there is more remaining, users may already see reduced latency when resources are replaced. For example, if changing a route from one backend service to another, RPCs may see less latency during the transition
• core: Log any exception during channel panic because of exception (3961a92). This prevents the exception from propagating up the stack on an arbitrary thread. Such exceptions are rarely interesting. Instead, the exception that caused the channel panic is the important one, and RPCs will still fail with its details
• util: Graceful switch to new LB when leaving CONNECTING (2e260a4). Previously when using xDS and the configuration changes the LB policy, the old LB policy is used until the new one is READY. Now the old LB policy is used until the new policy becomes READY, TRANSIENT_FAILURE, or IDLE
• core: Use java.time.Time.getNano directly in InstantTimeProvider. Previously reflection was used which would confuse R8 full mode (#​11977) (7507a9e)
• core: Avoid cancellation exceptions when notifying watchers that already have their connections cancelled (#​11934) (350f90e)
• rls: allow maxAge in RLS config to exceed 5 minutes if staleAge is set. Previously, the limit was 5 minutes, which isn't enough for some gRPC clients (#​11931) (c340f4a)
• xds: avoid unnecessary dns lookup for CIDR addresses (#​11932) (602aece)
• netty: Swap to UniformStreamByteDistributor (#​11954) (2f52a00). gRPC will no longer observe the HTTP/2 priorities, which were not used directly by gRPC and deprecated in RFC 9113
• core: Avoid Set.removeAll() when passing a possibly-large List (#​11994) (666136b)
• stub: trailersFromThrowable() metadata should be copied (#​11979) (a6e1c1f)

New Features

• xds: xDS-based HTTP CONNECT configuration (#​11861) (1219706)
• netty: Per-rpc authority verification against peer cert subject names. Overriding transport authority at rpc time is only allowed when using TlsChannelCredentials. The per-rpc authority verification feature is guarded by the environment variable GRPC_ENABLE_PER_RPC_AUTHORITY_CHECK in this release. When this is false or not set, the rpc will not fail when the authority verification fails but a warning will be logged. In a subsequent release the usage of this environment variable will be removed and RPCs will start failing if the authority doesn't match the peer certificate names. The environment variable is temporary; if you are depending on the existing insecure behavior, please file an issue (#​11724) (cdab410)

v1.71.0

API Changes

• xds: Enable Xds Client Fallback by default. This allows having a backup xDS server as described in gRFC A71-xds-fallback.md (#​11817) (176f3ee)
• protobuf: Experimental API marshallerWithRecursionLimit in ProtoUtils is now stabilized (#​11884) (90b1c4f)

Bug Fixes

• xds: Cluster weights should be uint32 (199a7ea). They were previously processed as int32, although the sum of weights was checked to be positive. So this would have caused a very large weight to never be selected and to reduce the chances of immediately-following clusters to be selected. There have been no reports of control planes using such large weights
• xds: Fix an unlikely infinite loop triggered by route update (199a7ea). Triggering required the old cluster to no longer be used, an RPC processing when the update arrived, and for a RPC to not match any route in the new config. There have been no reports of this actually happening
• core: Release data frame if it is received before the headers (dc316f7)

Improvements

• Replace jsr305's CheckReturnValue with Error Prone's (#​11811) (7b5d069)
• core: optimize number of buffer allocations for message sizes larger than 1 MB (#​11879) (5a7f350)
• core: Update the retry backoff range from [0, 1] to [0.8, 1.2] as per the A6 redefinition (#​11858) (44e92e2)
• core: include last pick status in status message when wait-for-ready RPC’s deadline expires (#​11851) (7585b16). This makes it much easier to debug connectivity issues when using wait-for-ready RPCs
• xds: Include max concurrent request limit in the error status for concurrent connections limit exceeded (#​11845) (0f5503e)
• netty, servlet: Remove 4096 min write buffer size because MessageFramer.flush() is being called between every message, so messages are never combined and the larger allocation just wastes memory. (4a10a38, 7153ff8)
• core: When ClientStreamObserver closes the response observer log the error message if this operation fails (#​11880) (302342c)
• bom: use gradle java-platform to build pom instead of custom xml generation (#​11875) (3142928)
• xds: Reuse filter interceptors on client-side across RPCs (c506190, b3db8c2). This was an internal refactor that should have no user-visible change
• alts: Enhance AltsContextUtil to allow getting the AltsContext on client-side (b1bc0a9)
• xds: Envoy proto sync to 2024-11-11 (#​11816) (b44ebce)

Documentation

• examples: Update HelloWorldServer to use Executor (#​11850) (16edf7a)
• examples: Add README for all examples lacking it (#​11676) (9e86299)

Dependencies

• Version upgrades (#​11874) (fc8571a)
• Upgrade netty-tcnative to 2.0.70 (122b683)
