v1.79.0: Release 1.79.0

Compare Source

API Changes

• mem: Add experimental API SetDefaultBufferPool to change the default buffer pool. (#​8806)

New Features

• pickfirst: Add support for weighted random shuffling of endpoints, as described in gRFC A113.
  • This is enabled by default, and can be turned off using the environment variable GRPC_EXPERIMENTAL_PF_WEIGHTED_SHUFFLING. (#​8864)
• xds: Implement :authority rewriting, as specified in gRFC A81. (#​8779)
• balancer/randomsubsetting: Implement the random_subsetting LB policy, as specified in gRFC A68. (#​8650)
  • Special Thanks: @​marek-szews
• server: Include status detail headers, if available, when terminating a stream during request header processing. (#​8754)
  • Special Thanks: @​joybestourous

Bug Fixes

• credentials/tls: Fix a bug where the port was not stripped from the authority override before validation. (#​8726)
  • Special Thanks: @​Atul1710
• xds/priority: Fix a bug causing delayed failover to lower-priority clusters when a higher-priority cluster is stuck in CONNECTING state. (#​8813)
• health: Fix a bug where health checks failed for clients using legacy compression options (WithDecompressor or RPCDecompressor). (#​8765)
  • Special Thanks: @​sanki92
• transport: Fix an issue where the HTTP/2 server could skip header size checks when terminating a stream early. (#​8769)
  • Special Thanks: @​joybestourous

Performance Improvements

• credentials/alts: Optimize read buffer alignment to reduce copies. (#​8791)
• mem: Optimize pooling and creation of buffer objects. (#​8784)
• transport: Reduce slice re-allocations by reserving slice capacity. (#​8797)

v1.78.0: Release 1.78.0

Compare Source

Behavior Changes

• client: Reject target URLs containing unbracketed colons in the hostname in Go version 1.26+. (#​8716)
  • Special Thanks: @​neild

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)
  • Special Thanks: @​twz123

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)
  • Special Thanks: @​iblancasa
• 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)
  • Special Thanks: @​cjc25
