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)

v1.76.0: Release 1.76.0

Dependencies

Bug Fixes

  • client: Return status INTERNAL when a server sends zero response messages for a unary or client-streaming RPC. (#​8523)
  • client: Fail RPCs with status INTERNAL instead of UNKNOWN upon receiving http headers with status 1xx and END_STREAM flag set. (#​8518)
  • pick_first: Fix race condition that could cause pick_first to get stuck in IDLE state on backend address change. (#​8615)

New Features

  • credentials: Add credentials/jwt package providing file-based JWT PerRPCCredentials (A97). (#​8431)

Performance Improvements

  • client: Improve HTTP/2 header size estimate to reduce re-allocations. (#​8547)
  • encoding/proto: Avoid redundant message size calculation when marshaling. (#​8569)

v1.75.1: Release 1.75.1

Compare Source

Bug Fixes

  • transport: Fix a data race while copying headers for stats handlers in the std lib http2 server transport. (#​8519)
  • xdsclient:
    • Fix a data race caused while reporting load to LRS. (#​8483)
    • Fix regression preventing empty node IDs when creating an LRS client. (#​8483)
  • server: Fix a regression preventing streams from being cancelled or timed out when blocked on flow control. (#​8528)

v1.75.0: Release 1.75.0

Compare Source

Behavior Changes

  • xds: Remove support for GRPC_EXPERIMENTAL_XDS_FALLBACK environment variable. Fallback support can no longer be disabled. (#​8482)
  • stats: Introduce DelayedPickComplete event, a type alias of PickerUpdated. (#​8465)
    • This (combined) event will now be emitted only once per call, when a transport is successfully selected for the attempt.
    • OpenTelemetry metrics will no longer have multiple "Delayed LB pick complete" events in Go, matching other gRPC languages.
    • A future release will delete the PickerUpdated symbol.
  • credentials: Properly apply grpc.WithAuthority as the highest-priority option for setting authority, above the setting in the credentials themselves. (#​8488)
    • Now that this WithAuthority is available, the credentials should not be used to override the authority.
  • round_robin: Randomize the order in which addresses are connected to in order to spread out initial RPC load between clients. (#​8438)
  • server: Return status code INTERNAL when a client sends more than one request in unary and server streaming RPC. (#​8385)
    • This is a behavior change but also a bug fix to bring gRPC-Go in line with the gRPC spec.

New Features

  • dns: Add an environment variable (GRPC_ENABLE_TXT_SERVICE_CONFIG) to provide a way to disable TXT lookups in the DNS resolver (by setting it to false). By default, TXT lookups are enabled, as they were previously. (#​8377)

Bug Fixes

  • xds: Fix regression preventing empty node IDs in xDS bootstrap configuration. (#​8476)
  • xds: Fix possible panic when certain invalid resources are encountered. (#​8412)
  • xdsclient: Fix a rare panic caused by processing a response from a closed server. (#​8389)
  • stats: Fix metric unit formatting by enclosing non-standard units like call and endpoint in curly braces to comply with UCUM and gRPC OpenTelemetry guidelines. (#​8481)
  • xds: Fix possible panic when clusters are removed from the xds configuration. (#​8428)
  • xdsclient: Fix a race causing "resource doesn not exist" when rapidly subscribing and unsubscribing to the same resource. (#​8369)
  • client: When determining the authority, properly percent-encode (if needed, which is unlikely) when the target string omits the hostname and only specifies a port (grpc.NewClient(":<port-number-or-name>")). (#​8488)
