Release Notes

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

v1.84.0: Release 1.84.0

Compare Source

Behavior Changes

  • stats/otel: The grpc.lb.pick_first.* metrics have been removed and replaced with grpc.subchannel.* metrics. See gRFC A94 for more details. (#​9215)

New Features

  • xds: Add support for contains_match in route header matchers. (#​9223)

Bug Fixes

  • client: Fix a bug where a ClientConn could get permanently stuck in IDLE when an RPC was canceled during stream creation. Previously, such cancellations triggered stream cleanup twice, corrupting the channel's idleness state and causing subsequent RPCs to fail with deadline exceeded errors. (#​9191)
  • client: Fix a bug where non-gRPC HTTP responses ending with an empty DATA frame failed the RPC with status code Internal instead of preserving the HTTP-mapped status code and response body. (#​9217)
  • credentials: Validate metadata returned by per-RPC credentials, failing the RPC with status code Internal if invalid keys or values are found. Previously, invalid metadata from credentials was sent to the server in outgoing HTTP/2 requests. (#​9202)
  • credentials/sts: Prevent potential token leakage by disallowing HTTP redirects during STS token exchange. Previously, 3xx redirects were followed automatically, replaying the request body containing authentication tokens to the redirect destination. (#​9299)
  • randomsubsetting: Ignore endpoints that contain no addresses. Previously, this could cause the policy to panic while computing hashes. (#​9259)
  • stats/otel: Ensure method names are populated in trace spans when metrics are disabled. Previously, running with tracing enabled and metrics disabled resulted in server trace spans lacking the RPC method name (recording only "Recv."). (#​9262)
  • transport: Return io.ErrUnexpectedEOF when EOF is encountered after partial header or message body reads. Previously, partial reads could return a plain io.EOF, failing to distinguish truncated data from a clean end of stream. (#​9204)
  • transport: Validate metadata supplied by balancers (in PickResult.Metadata) and resolver addresses, failing the RPC with status code Internal if invalid keys or values are found. Previously, invalid metadata from these sources was sent to the server in outgoing HTTP/2 requests. (#​9203)
  • xds: Fix a rare corner case that could prevent a cluster from being removed when it is no longer in use. (#​9140)
  • xds: Fix panic during route matching for routes containing header matchers with empty exact_match strings. (#​9223)
  • xds: Reject routes containing header matchers with empty prefix_match or suffix_match strings. Previously, this caused a panic during route matching. (#​9223)
  • xds: Fix EDS drop policies being applied at a much lower rate than configured due to an integer overflow. (#​9257)
  • xds: Reject EDS resources containing drop policies with unsupported denominators. Previously, such resources caused the client to panic when calculating drop rates. (#​9218)
  • xds/rbac: Reject RBAC configurations containing nested Principal or Permission rules with :scheme or grpc- prefixed header matchers. Previously, such configurations could cause DENY policies to fail open. (#​9258)
  • xds/rbac: Rewrite host header matchers to :authority in nested Principal and Permission rules. Previously, this rewrite only applied to top-level rules, causing nested host matchers to never match incoming requests and DENY policies to fail open. (#​9258)
  • xds/rbac: Reject CidrRanges with an unset prefix length. Previously, an omitted prefix_len field caused a panic during RBAC configuration parsing. (#​9250)

Performance Improvements

  • transport: Avoid a heap allocation when flushing shared write buffers. (#​9233)
  • credentials/alts: Support dynamic frame size negotiation and add the GRPC_GO_EXPERIMENTAL_ALTS_MAX_FRAME_SIZE environment variable (default 4KiB, max 512KiB) to configure the maximum ALTS record frame size. (#​9268)

v1.83.2: Release 1.83.2

Compare Source

Security

  • server: Reject requests missing both :authority and Host headers with HTTP 400 and status Internal. (#​9365)

v1.83.1: Release 1.83.1

Compare Source

Security

  • xds/rbac: Fix a bug where nested Principal or Permission rules with :scheme or grpc- prefixed header matchers were not rejected, which could cause DENY rules to fail open. (#​9258)
  • xds/rbac: Fix a bug where the host header matcher was not being replaced with :authority in nested Principal or Permission rules. (#​9258)
  • xds/rbac: Fix a bug where a header matcher whose name was not lowercase, such as X-Role, matched no header, which could cause DENY rules to fail open. (#​9332)
  • xds/rbac: Fix a bug where a :scheme or grpc- prefixed header matcher was accepted when its name was not lowercase. (#​9332)
  • xds/rbac: Fix a bug where a Host header matcher was not replaced with :authority. (#​9332)

Performance

  • transport: Restrict memory overhead of buffering small data frames. (#​9331)

v1.83.0: Release 1.83.0

Compare Source

Security

  • server: Stop reading from connections when flooded by HTTP/2 frames to mitigate resource exhaustion. The default value for this limit is 100 frames, excluding DATA and HEADERS, and may be changed by setting environment variable GRPC_GO_EXPERIMENTAL_CONTROL_BUFFER_THROTTLE_LIMIT.
  • xds/rbac: Support Metadata and RequestedServerName permissions matcher fields. If present in a DENY rule, previously these would be ignored and fail-open.
  • xds/rbac: Fix panic when parsing unsupported fields in NotRule/NotId permissions.
  • xds/rbac: Support the deprecated source_ip principal identifier by treating it as equivalent to direct_remote_ip.
  • xds: Fix panic when parsing route header matchers configured with empty exact_match, prefix_match, or suffix_match strings. (#​9223)

New Features

  • xds/googlec2p: Enable DirectPath over Interconnect support for on-premises clients via the force-xds target URI query parameter. (#​9133)
  • xds: Enable xDS configuration to control which fields get propagated from ORCA backend metric reports to LRS load reports. (#​9145)
  • authz: Add OnPolicyUpdate callback to FileWatcherOptions to notify when an authz policy is loaded or updated. (#​9142)
  • xds: Add support for the GCP Authentication HTTP Filter, which automatically fetches and attaches GCP Service Account Identity JWT tokens to outgoing RPCs.
    • This feature can be enabled by setting environment variable GRPC_EXPERIMENTAL_XDS_GCP_AUTHENTICATION_FILTER=true. (#​9119)
  • xds: Add support for xDS-based HTTP CONNECT proxies.
    • This feature can be enabled by setting environment variable GRPC_EXPERIMENTAL_XDS_HTTP_CONNECT=true. (#​9151)
  • xds: Add support for contains_match in route header matchers. (#​9223)

Bug Fixes

  • credentials/alts: Fix panic when processing malformed frames by validating that the message frame length exceeds the message type field size. (#​9197)
  • grpc: Fix compilation on Plan 9 targets (GOOS=plan9), broken since v1.81.0. (#​9255)

v1.82.2: Release 1.82.2

v1.82.0: Release 1.82.0

Compare Source

Behavior Changes

  • server: Remove support for GRPC_GO_EXPERIMENTAL_DISABLE_STRICT_PATH_CHECKING environment varibale. Strict incoming RPC path validation (which has been the default since v1.79.3) can no longer be disabled. (#​9112)
  • transport: Add environment variable to change the default max header list size from 16MB to 8KB. This may be enabled by setting GRPC_GO_EXPERIMENTAL_ENABLE_8KB_DEFAULT_HEADER_LIST_SIZE=true. This will be enabled by default in a subsequent release. (#​9019)
  • balancer: Load Balancing policy registry is now case-sensitive. Set GRPC_GO_EXPERIMENTAL_CASE_SENSITIVE_BALANCER_REGISTRIES=false (and file an issue) to revert to case-insensitive behavior. (#​9017)

New Features

  • experimental/stats: Expose a new API, NewContextWithLabelCallback, to register a callback that is invoked when telemetry labels are added. (#​8877)
  • client: Return a portion of the response body in the error message, when the client receives an unexpected non-gRPC HTTP response, to make debugging easier. (#​8929)
  • server: Add environment variable GRPC_GO_SERVER_GOROUTINE_LABELS that controls setting runtime/pprof.Labels on goroutines spawned by the server. Set GRPC_GO_SERVER_GOROUTINE_LABELS=grpc.method=true to add the grpc.method label on goroutines spawned to handle incoming requests. (#​9082)

Bug Fixes

  • xds/server: Fix a memory leak of HTTP filter instances occurring when route configurations are updated in-place during a Route Discovery Service (RDS) update. (#​9138)
  • grpc: In the deprecated gzip Compressor (used via the deprecated WithCompressor dial option), enforce the MaxRecvMsgSize limit on the decompressed message buffer, preventing excessive memory allocation from highly compressed payloads. (#​9114)
  • stats/opentelemetry: Record retry attempts, grpc.previous-rpc-attempts, at the call level and not the attempt level. (#​8923)
  • encoding: Ensure Close() is always called on readers returned from Compressor.Decompress if possible. (#​9135)
  • channelz: Fix the LastMessageSentTimestamp and LastMessageReceivedTimestamp fields in SocketMetrics to ensure they contain correct timestamp values. (#​9109)

v1.81.1: Release 1.81.1

Compare Source

Security

  • xds/rbac: Fix a potential authorization bypass caused by incorrectly falling through URI/DNS SANs to Subject Distinguished Name (DN) when matching the authenticated principal name. With this fix, only the first non-empty identity source will be used, as per gRFC A41. (#​9111)

v1.81.0: Release 1.81.0

Compare Source

Behavior Changes

  • balancer/rls: Switch gauge metrics to asynchronous emission (once per collection cycle) to reduce telemetry noise and align with other gRPC language implementations. (#​8808)

Dependencies

  • Minimum supported Go version is now 1.25. (#​8969)

Bug Fixes

  • xds: Use the leaf cluster's security config for the TLS handshake instead of the aggregate cluster's config. (#​8956)
  • transport: Send a RST_STREAM when receiving an END_STREAM when the stream is not already half-closed. (#​8832)
  • xds: Fix ADS resource name validation to prevent a panic. (#​8970)

New Features

  • grpc/stats: Add support for custom labels in per-call metrics (gRFC A108). (#​9008)
  • xds: Add support for Server Name Indication (SNI) and SAN validation (gRFC A101). Disabled by default. To enable, set GRPC_EXPERIMENTAL_XDS_SNI=true environment variable. (#​9016)
  • xds: Add support to control which fields get propagated from ORCA backend metric reports to LRS load reports (gRFC A85). Disabled by default. To enable, set GRPC_EXPERIMENTAL_XDS_ORCA_LRS_PROPAGATION=true. (#​9005)
  • xds: Add metrics to track xDS client connectivity and cached resource state (gRFC A78). (#​8807)
  • stats/otel: Enhance grpc.subchannel.disconnections metric by adding disconnection reason to the grpc.disconnect_error label (gRFC A94). This provides granular insights into why subchannels are closing. (#​8973)
  • mem: Add mem.Buffer.Slice() API to slice the buffer like a slice. (#​8977)

Performance Improvements

  • alts: Pool read buffers to lower memory utilization when sockets are unreadable. (#​8964)
  • transport: Pool HTTP/2 framer read buffers to reduce idle memory consumption. Currently limited to Linux for ALTS and non-encrypted transports (TCP, Unix). To disable, set GRPC_GO_EXPERIMENTAL_HTTP_FRAMER_READ_BUFFER_POOLING=false and report any issues. (#​9032)

v1.80.0

Compare Source

v1.79.3: Release 1.79.3

Compare Source

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)

v1.79.2: Release 1.79.2

Compare Source

Bug Fixes

  • 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)
  • server: Include status detail headers, if available, when terminating a stream during request header processing. (#​8754)

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)

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)
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)
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)
  • 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)

v1.77.0: Release 1.77.0

Compare Source

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)
  • 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)
  • 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

New Features

  • outlierdetection: Add metrics specified in gRFC A91. (#​8644)
  • stats/opentelemetry: Add support for optional label grpc.lb.backend_service in per-call metrics (#​8637)

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

v1.76.0: Release 1.76.0

Compare Source

Dependencies

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)
  • 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)

Performance Improvements

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