Release Notes

grpc/grpc-go (google.golang.org/grpc)

v1.76.0: Release 1.76.0

Compare Source

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)

New Features

• credentials: Add credentials/jwt package providing file-based JWT PerRPCCredentials (A97). (#​8431)
  • Special Thanks: @​dimpavloff

Performance Improvements

• client: Improve HTTP/2 header size estimate to reduce re-allocations. (#​8547)
• encoding/proto: Avoid redundant message size calculation when marshaling. (#​8569)
  • Special Thanks: @​rs-unity

v1.75.1: Release 1.75.1

Compare Source

Bug Fixes

• transport: Fix a data race while copying headers for stats handlers in the std lib http2 server transport. (#​8519)
• xdsclient:
  • Fix a data race caused while reporting load to LRS. (#​8483)
  • Fix regression preventing empty node IDs when creating an LRS client. (#​8483)
• server: Fix a regression preventing streams from being cancelled or timed out when blocked on flow control. (#​8528)

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)

v1.74.3: Release 1.74.3

Compare Source

Bug Fixes

• xds: Fix a regression preventing empty node IDs in the bootstrap configuration. (#​8476 , #​8483)
• xdsclient: Fix a data race caused while reporting load to LRS. (#​8483)
• server: Fix a regression preventing streams from being cancelled or timed out when blocked on flow control. (#​8528)

v1.74.2: Release 1.74.2

Compare Source

New Features

• grpc: introduce new DialOptions and ServerOptions (WithStaticStreamWindowSize, WithStaticConnWindowSize, StaticStreamWindowSize, StaticConnWindowSize) that force fixed window sizes for all HTTP/2 connections. By default, gRPC uses dynamic sizing of these windows based upon a BDP estimation algorithm. The existing options (WithInitialWindowSize, etc) also disable BDP estimation, but this behavior will be changed in a following release. (#​8283)

API Changes

• balancer: add ExitIdle method to Balancer interface. Earlier, implementing this method was optional. (#​8367)

Behavior Changes

• xds: Remove the GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST environment variable that allows disabling the least request balancer with xDS. Least request was made available by default with xDS in v1.72.0. (#​8248)
  • Special Thanks: @​atollena
• server: allow 0s grpc-timeout header values, which older gRPC-Java versions could send. This restores the behavior of grpc-go before v1.73.0. (#​8439)

Bug Fixes

• googledirectpath: avoid logging the error message Attempt to set a bootstrap configuration... when creating multiple directpath channels. (#​8419)

Performance Improvements

• transport: reduce heap allocations by pooling objects and avoiding method-to-closure conversions. (#​8361)
• transport: reduce heap allocations by re-using mem.Reader objects. (#​8360)

Documentation

• examples: add examples to demonstrate enabling experimental metrics using the OpenTelemetry plugin. (#​8388)
  • Special Thanks: @​vinothkumarr227

v1.74.1: Release 1.74.1

Compare Source

Version 1.74.1 retracts release v1.74.0 and itself. Release 1.74.0 was accidentally tagged on the wrong commit and should not be used. Version 1.73.0 should be used until 1.74.2 is released.

Compare Source

New Features

• balancer/ringhash: move LB policy from xds/internal to exported path to facilitate use without xds (#​8249)
• xds: enable least request LB policy by default. It can be disabled by setting GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST=false in your environment. (#​8253)
• grpc: add a CallAuthority Call Option that can be used to overwrite the http :authority header on per-RPC basis. (#​8068)
• stats/opentelemetry: add trace event for name resolution delay. (#​8074)
• health: added List method to gRPC Health service. (#​8155)
  • Special Thanks: @​marcoshuck
• ringhash: implement features from gRFC A76. (#​8159)
• xds: add functionality to support SPIFFE Bundle Maps as roots of trust in XDS which can be enabled by setting GRPC_EXPERIMENTAL_XDS_MTLS_SPIFFE=true. (#​8167, #​8180, #​8229, #​8343)

Bug Fixes

• xds: locality ID metric label is changed to make it consistent with gRFC A78. (#​8256)
• client: fail RPCs on the client when using extremely short contexts that expire before the grpc-timeout header is created. (#​8312)
• server: non-positive grpc-timeout header values are now rejected. This is consistent with the gRPC protocol spec. (#​8290)
  • Special Thanks: @​evanj
• xds: fix reported error string when LRS load reporting interval is invalid. (#​8224)
  • Special Thanks: @​alingse

Performance Improvements

• server: improve performance of RPC handling by avoid a status proto copy (#​8282)
  • Special Thanks: @​evanj

Documentation

Compare Source

Dependencies

• Minimum supported Go version is now 1.23 (#​8108)

API Changes

• resolver: add experimental AddressMapV2 with generics to ultimately replace AddressMap. Deprecate AddressMap for deletion (#​8187)

New Features

• xds: add grpc.xds_client.server_failure counter metric on xDS client to record connectivity errors (#​8203)
• balancer/rls: allow maxAge to exceed 5 minutes if staleAge is set in the LB policy configuration (#​8137)
• ringhash: implement gRFC A76 improvements. (#​8159)
• pickfirst: The new pick first LB policy is made the default. The new LB policy implements the Happy Eyeballs algorithm. To disable the new policy set the environment variable GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST to false (case insensitive).

Hi @red-hat-konflux[bot]. Thanks for your PR.

I'm waiting for a openshift 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.
