Bumps google.golang.org/grpc from 1.70.0 to 1.79.3.

Release notes

Sourced from google.golang.org/grpc's releases.

Release 1.79.3

Security

  • server: fix an authorization bypass where malformed :path headers (missing the leading slash) could bypass path-based restricted "deny" rules in interceptors like grpc/authz. Any request with a non-canonical path is now immediately rejected with an Unimplemented error. (#8981)

Release 1.79.2

Bug Fixes

  • stats: Prevent redundant error logging in health/ORCA producers by skipping stats/tracing processing when no stats handler is configured. (grpc/grpc-go#8874)

Release 1.79.1

Bug Fixes

Release 1.79.0

API Changes

  • mem: Add experimental API SetDefaultBufferPool to change the default buffer pool. (#8806)
  • experimental/stats: Update MetricsRecorder to require embedding the new UnimplementedMetricsRecorder (a no-op struct) in all implementations for forward compatibility. (#8780)

Behavior Changes

  • balancer/weightedtarget: Remove handling of Addresses and only handle Endpoints in resolver updates. (#8841)

New Features

  • experimental/stats: Add support for asynchronous gauge metrics through the new AsyncMetricReporter and RegisterAsyncReporter APIs. (#8780)
  • 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)

Bug Fixes

  • credentials/tls: Fix a bug where the port was not stripped from the authority override before validation. (#8726)
  • 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)
  • transport: Fix an issue where the HTTP/2 server could skip header size checks when terminating a stream early. (#8769)
  • server: Propagate status detail headers, if available, when terminating a stream during request header processing. (#8754)

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)

Summary by cubic

Upgrade google.golang.org/grpc to 1.79.3 to pick up a security fix and recent bug fixes. Also updates the toolchain to Go 1.24.0 and refreshes related deps.

  • Dependencies

    • Bumped google.golang.org/grpc from 1.70.0 to 1.79.3 (includes strict path validation to prevent bypass of path-based deny rules).
    • Set go to 1.24.0.
    • Upgraded key transitive deps: google.golang.org/protobuf to 1.36.10, golang.org/x/{crypto,net,sync,sys,term,text}, gonum.org/v1/gonum to 0.16.0.
    • Promoted github.com/spf13/viper to a direct dependency.
  • Migration

    • Requires Go 1.24.0 to build.
    • If you run a gRPC server with path-based auth checks, note that non-canonical paths are now rejected; update tests/configs if they relied on old behavior.

Written for commit d70c85d. Summary will update on new commits.
