Behavior Changes
  • client: Reject target URLs containing unbracketed colons in the hostname in Go version 1.26+. (#​8716)
New Features
  • stats/otel: Add backend service label to wrr metrics as part of A89. (#​8737)
  • stats/otel: Add subchannel metrics (without the disconnection reason) to eventually replace the pickfirst metrics. (#​8738)
  • client: Wait for all pending goroutines to complete when closing a graceful switch balancer. (#​8746)
Bug Fixes
  • transport/client : Return status code Unknown on malformed grpc-status. (#​8735)
  • client: Add experimental.AcceptCompressors so callers can restrict the grpc-accept-encoding header advertised for a call. (#​8718)
  • xds: Fix a bug in StringMatcher where regexes would match incorrectly when ignore_case is set to true. (#​8723)
  • xds/resolver:
    • Drop previous route resources and report an error when no matching virtual host is found.
    • Only log LDS/RDS configuration errors following a successful update and retain the last valid resource to prevent transient failures. (#​8711)
  • client:
    • Change connectivity state to CONNECTING when creating the name resolver (as part of exiting IDLE).
    • Change connectivity state to TRANSIENT_FAILURE if name resolver creation fails (as part of exiting IDLE).
    • Change connectivity state to IDLE after idle timeout expires even when current state is TRANSIENT_FAILURE.
    • Fix a bug that resulted in OnFinish call option not being invoked for RPCs where stream creation failed. (#​8710)
  • xdsclient: Fix a race in the xdsClient that could lead to resource-not-found errors. (#​8627)
Performance Improvements
  • mem: Round up to nearest 4KiB for pool allocations larger than 1MiB. (#​8705)

v1.77.0: Release 1.77.0

Compare Source

API Changes

  • mem: Replace the Reader interface with a struct for better performance and maintainability. (#​8669)

Behavior Changes

  • balancer/pickfirst: Remove support for the old pick_first LB policy via the environment variable GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST=false. The new pick_first has been the default since v1.71.0. (#​8672)

Bug Fixes

  • xdsclient: Fix a race condition in the ADS stream implementation that could result in resource-not-found errors, causing the gRPC client channel to move to TransientFailure. (#​8605)
  • client: Ignore HTTP status header for gRPC streams. (#​8548)
  • client: Set a read deadline when closing a transport to prevent it from blocking indefinitely on a broken connection. (#​8534)
  • client: Fix a bug where default port 443 was not automatically added to addresses without a specified port when sent to a proxy.
    • Setting environment variable GRPC_EXPERIMENTAL_ENABLE_DEFAULT_PORT_FOR_PROXY_TARGET=false disables this change; please file a bug if any problems are encountered as we will remove this option soon. (#​8613)
  • balancer/pickfirst: Fix a bug where duplicate addresses were not being ignored as intended. (#​8611)
  • server: Fix a bug that caused overcounting of channelz metrics for successful and failed streams. (#​8573)
  • balancer/pickfirst: When configured, shuffle addresses in resolver updates that lack endpoints. Since gRPC automatically adds endpoints to resolver updates, this bug only affects custom LB policies that delegate to pick_first but don't set endpoints. (#​8610)
  • mem: Clear large buffers before re-using. (#​8670)

Performance Improvements

New Features

  • outlierdetection: Add metrics specified in gRFC A91. (#​8644)
  • stats/opentelemetry: Add support for optional label grpc.lb.backend_service in per-call metrics (#​8637)
  • xds: Add support for JWT Call Credentials as specified in gRFC A97. Set environment variable GRPC_EXPERIMENTAL_XDS_BOOTSTRAP_CALL_CREDS=true to enable this feature. (#​8536)
  • experimental/stats: Add support for up/down counters. (#​8581)
