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)
  • Special Thanks: @​davinci26
• xds: Fix possible panic when certain invalid resources are encountered. (#​8412)
  • Special Thanks: @​wooffie
• 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)
