Bumps google.golang.org/grpc from 1.75.1 to 1.77.0.

Release notes

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

Release 1.77.0

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)

Special Thanks: @jgold2-stripe

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)

Special Thanks: @hugehoo

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

transport: Reduce heap allocations to reduce time spent in garbage collection. (#8624, #8630, #8639, #8668)

transport: Avoid copies when reading and writing Data frames. (#8657, #8667)

mem: Avoid clearing newly allocated buffers. (#8670)

New Features

outlierdetection: Add metrics specified in gRFC A91. (#8644)

Special Thanks: @davinci26, @PardhuKonakanchi

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)

Special Thanks: @dimpavloff

experimental/stats: Add support for up/down counters. (#8581)

Release 1.76.0

Dependencies

Minimum supported Go version is now 1.24 (#8509)

Special Thanks: @kevinGC

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)

Special Thanks: @vinothkumarr227

pick_first: Fix race condition that could cause pick_first to get stuck in IDLE state on backend address change. (#8615)
