Release Notes

grpc/grpc-go (google.golang.org/grpc)

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)

This pull request performs a comprehensive update of various dependencies across the Go, .NET, and Java components of the project. The updates primarily focus on bringing the Google Cloud Spanner client libraries, gRPC, and related infrastructure components to their latest stable versions, ensuring the project benefits from the most recent bug fixes, performance optimizations, and newly introduced functionalities from these upstream projects.

Highlights

  • Go Dependencies Updated: Multiple Go dependencies, including google.golang.org/grpc (to v1.77.0), OpenTelemetry components, and xDS related packages, have been updated to their latest versions, bringing various bug fixes, performance improvements, and new features.
  • .NET Spanner Client Libraries Updated: The .NET Google Cloud Spanner client libraries, specifically Google.Cloud.Spanner.Admin.Database.V1, Google.Cloud.Spanner.Data, and Google.Cloud.Spanner.V1, have been updated from 5.6.0 to 5.7.0.
  • Java Spanner BOM Updated: The com.google.cloud:google-cloud-spanner-bom for Java has been updated from 6.102.1 to 6.103.0, which includes new features like xDS client metrics and exposing AutoscalingConfig in InstancePartition, along with several bug fixes and internal dependency updates.
  • gRPC-Go v1.77.0 Enhancements: The grpc-go update includes API changes (replacing the Reader interface), behavior changes (removing old pick_first LB policy support), fixes for race conditions and read deadlines, performance improvements through reduced heap allocations, and new features such as outlier detection metrics and JWT Call Credentials support.

Code Review

This pull request updates several dependencies across Go, .NET, and Java projects. The most significant change is the upgrade of google.golang.org/grpc to v1.77.0, which removes support for an old, experimental load balancing policy configuration. I've added comments to the go.mod files to highlight this potential breaking change. The other dependency updates appear to be minor and non-breaking. Please review the comments and ensure the gRPC update does not adversely affect your services.

The update to google.golang.org/grpc to version v1.77.0 includes a behavior change that removes support for the old pick_first load balancing policy. This was previously configurable via the GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST=false environment variable. The new pick_first policy has been the default since v1.71.0. Please verify that the project is not relying on the old pick_first policy by setting this environment variable, as it will no longer have any effect.
