dependabot · 2025-12-26T04:05:02Z

Bumps google.golang.org/grpc from 1.76.0 to 1.78.0.

Release notes

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

Release 1.78.0

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

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

Hi @dependabot[bot]. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@rikatz It looks like this PR only attempts to bump the dep inside the ./conformance directory, but ../hack/verify-codegen.sh percolates this change upwards to go.mod and go.sum as an indirect dep, possibly some additional updates needed to the Dependabot config or verify scripts...

Probably better to fix the generation code instead of just pushing up ad-hoc fixes.
