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)
- Special Thanks: @nvxbug

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)
- Special Thanks: @utkuozdemir
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)
- Special Thanks: @chengxilo
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)
- Special Thanks: @buger
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)
- Special Thanks: @nvxbug
randomsubsetting: Ignore endpoints that contain no addresses. Previously, this could cause the policy to panic while computing hashes. (#9259)
- Special Thanks: @fallintoplace
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)
- Special Thanks: @buger
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)
- Special Thanks: @buger
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)
- Special Thanks: @nvxbug
xds: Reject routes containing header matchers with empty prefix_match or suffix_match strings. Previously, this caused a panic during route matching. (#9223)
- Special Thanks: @nvxbug
xds: Fix EDS drop policies being applied at a much lower rate than configured due to an integer overflow. (#9257)
- Special Thanks: @nvxbug
xds: Reject EDS resources containing drop policies with unsupported denominators. Previously, such resources caused the client to panic when calculating drop rates. (#9218)
- Special Thanks: @nvxbug
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)
- Special Thanks: @nvxbug
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)
- Special Thanks: @nvxbug
xds/rbac: Reject CidrRanges with an unset prefix length. Previously, an omitted prefix_len field caused a panic during RBAC configuration parsing. (#9250)
- Special Thanks: @nvxbug

Performance Improvements

transport: Avoid a heap allocation when flushing shared write buffers. (#9233)
- Special Thanks: @zaidoon1
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)

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

- Special Thanks: @dfinkel

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)
- Special Thanks: @evilgensec
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)

`v1.80.0`: Release 1.80.0

Compare Source

Behavior Changes

balancer: log a warning if a balancer is registered with uppercase letters, as balancer names should be lowercase. In a future release, balancer names will be treated as case-insensitive; see #5288 for details. (#8837)
xds: update resource error handling and re-resolution logic (#8907)
- Re-resolve all LOGICAL_DNS clusters simultaneously when re-resolution is requested.
- Fail all in-flight RPCs immediately upon receipt of listener or route resource errors, instead of allowing them to complete.

Bug Fixes

xds: support the LB policy configured in LOGICAL_DNS cluster resources instead of defaulting to pick_first. (#8733)
credentials/tls: perform per-RPC authority validation against the leaf certificate instead of the entire peer certificate chain. (#8831)
xds: enabling A76 ring hash endpoint keys no longer causes EDS resources with invalid proxy metadata to be NACKed when HTTP CONNECT (gRFC A86) is disabled. (#8875)
xds: validate that the sum of endpoint weights in a locality does not exceed the maximum uint32 value. (#8899)

Performance Improvements

credentials/alts: pool write buffers to reduce memory allocations and usage. (#8919)
grpc: enable the use of pooled write buffers for buffering HTTP/2 frame writes by default. This reduces memory usage when connections are idle. Use the WithSharedWriteBuffer dial option or the SharedWriteBuffer server option to disable this feature. (#8957)
xds/priority: stop caching child LB policies removed from the configuration. This will help reduce memory and cpu usage when localities are constantly switching between priorities. (#8997)

- Special Thanks: @iblancasa

Bug Fixes

xds: Fix a bug in StringMatcher where regexes would match incorrectly when ignore_case is set to true. (#8723)
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).

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

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)

API Changes

balancer: Custom LB policies that record metrics must use the new MetricsRecorder method on Balancer.ClientConn instead of the removed Balancer.BuildOptions.MetricsRecorder field to obtain a metrics recorder. (#8027)
balancer: balancer.ClientConn implementations must now embed a delegate implementation. This allows grpc-go to add new methods to the interface and remain backward compatible. (#8026)

Behavior Changes

client: reject service configs containing an invalid retryPolicy in accordance with gRFCs A21 and A6. (#7905)
- Note that this is a potential breaking change for some users using an invalid configuration, but continuing to allow this behavior would violate our cross-language compatibility requirements.

New Features

xdsclient: fallback to a secondary management server (if specified in the bootstrap configuration) when the primary is down is enabled by default. Can be disabled by setting the environment variable GRPC_EXPERIMENTAL_XDS_FALLBACK to false. (#7949)
experimental/credentials: experimental transport credentials are added which don't enforce ALPN. (#7980)
- These credentials will be removed in an upcoming grpc-go release. Users must not rely on these credentials directly. Instead, they should either vendor a specific version of gRPC or copy the relevant credentials into their own codebase if absolutely necessary.

Bug Fixes

xds: fix a possible deadlock that happens when both the client application and the xDS management server (responsible for configuring the client) are using the xds:/// scheme in their target URIs. (#8011)

See [gRFC A94](https://github.com/grpc/proposal/blob/master/A94-subchannel-otel-metrics.md) for more details. ([#9215](https://github.com/grpc/grpc-go/issues/9215)) ### New Features - xds: Add support for `contains_match` in route header matchers. ([#9223](https://github.com/grpc/grpc-go/issues/9223)) - Special Thanks: [@nvxbug](https://github.com/nvxbug) ### 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](https://github.com/grpc/grpc-go/issues/9191)) - Special Thanks: [@utkuozdemir](https://github.com/utkuozdemir) - 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](https://github.com/grpc/grpc-go/issues/9217)) - Special Thanks: [@chengxilo](https://github.com/chengxilo) - 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.

Previously, 3xx redirects were followed automatically, replaying the request body containing authentication tokens to the redirect destination. ([#9299](https://github.com/grpc/grpc-go/issues/9299)) - Special Thanks: [@nvxbug](https://github.com/nvxbug) - randomsubsetting: Ignore endpoints that contain no addresses. Previously, this could cause the policy to panic while computing hashes. ([#9259](https://github.com/grpc/grpc-go/issues/9259)) - Special Thanks: [@fallintoplace](https://github.com/fallintoplace) - 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](https://github.com/grpc/grpc-go/issues/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](https://github.com/grpc/grpc-go/issues/9204)) - Special Thanks: [@buger](https://github.com/buger) - 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, such resources caused the client to panic when calculating drop rates. ([#9218](https://github.com/grpc/grpc-go/issues/9218)) - Special Thanks: [@nvxbug](https://github.com/nvxbug) - 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](https://github.com/grpc/grpc-go/issues/9258)) - Special Thanks: [@nvxbug](https://github.com/nvxbug) - 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](https://github.com/grpc/grpc-go/issues/9258)) - Special Thanks: [@nvxbug](https://github.com/nvxbug) - xds/rbac: Reject `CidrRanges` with an unset prefix length.

([#8807](https://github.com/grpc/grpc-go/issues/8807)) - stats/otel: Enhance `grpc.subchannel.disconnections` metric by adding disconnection reason to the `grpc.disconnect_error` label ([gRFC A94](https://github.com/grpc/proposal/blob/master/A94-subchannel-otel-metrics.md)). This provides granular insights into why subchannels are closing. ([#8973](https://github.com/grpc/grpc-go/issues/8973)) - mem: Add `mem.Buffer.Slice()` API to slice the buffer like a slice. ([#8977](https://github.com/grpc/grpc-go/issues/8977)) - Special Thanks: [@ash2k](https://github.com/ash2k) ### Performance Improvements - alts: Pool read buffers to lower memory utilization when sockets are unreadable. ([#8964](https://github.com/grpc/grpc-go/issues/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.

In a future release, balancer names will be treated as case-insensitive; see [#5288](https://github.com/grpc/grpc-go/issues/5288) for details. ([#8837](https://github.com/grpc/grpc-go/issues/8837)) - xds: update resource error handling and re-resolution logic ([#8907](https://github.com/grpc/grpc-go/issues/8907)) - Re-resolve all `LOGICAL_DNS` clusters simultaneously when re-resolution is requested. - Fail all in-flight RPCs immediately upon receipt of listener or route resource errors, instead of allowing them to complete. ### Bug Fixes - xds: support the LB policy configured in `LOGICAL_DNS` cluster resources instead of defaulting to `pick_first`. ([#8733](https://github.com/grpc/grpc-go/issues/8733)) - credentials/tls: perform per-RPC authority validation against the leaf certificate instead of the entire peer certificate chain. ([#8831](https://github.com/grpc/grpc-go/issues/8831)) - xds: enabling A76 ring hash endpoint keys no longer causes EDS resources with invalid proxy metadata to be NACKed when HTTP CONNECT (gRFC A86) is disabled. ([#8875](https://github.com/grpc/grpc-go/issues/8875)) - xds: validate that the sum of endpoint weights in a locality does not exceed the maximum `uint32` value.

([#8922](https://github.com/grpc/grpc-go/issues/8922)) ### Performance Improvements - credentials/alts: pool write buffers to reduce memory allocations and usage. ([#8919](https://github.com/grpc/grpc-go/issues/8919)) - grpc: enable the use of pooled write buffers for buffering HTTP/2 frame writes by default. This reduces memory usage when connections are idle. Use the [WithSharedWriteBuffer](https://pkg.go.dev/google.golang.org/grpc#WithSharedWriteBuffer) dial option or the [SharedWriteBuffer](https://pkg.go.dev/google.golang.org/grpc#SharedWriteBuffer) server option to disable this feature. ([#8957](https://github.com/grpc/grpc-go/issues/8957)) - xds/priority: stop caching child LB policies removed from the configuration. This will help reduce memory and cpu usage when localities are constantly switching between priorities. ([#8997](https://github.com/grpc/grpc-go/issues/8997)) - mem: add a faster tiered buffer pool; use the experimental [mem.NewBinaryTieredBufferPool](https://pkg.go.dev/google.golang.org/grpc/mem@master#NewBinaryTieredBufferPool) function to create such pools.

([#8605](https://github.com/grpc/grpc-go/issues/8605)) - client: Ignore HTTP status header for gRPC streams. ([#8548](https://github.com/grpc/grpc-go/issues/8548)) - client: Set a read deadline when closing a transport to prevent it from blocking indefinitely on a broken connection. ([#8534](https://github.com/grpc/grpc-go/issues/8534)) - Special Thanks: [@jgold2-stripe](https://github.com/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](https://github.com/grpc/grpc-go/issues/8613)) - balancer/pickfirst: Fix a bug where duplicate addresses were not being ignored as intended.

([#8573](https://github.com/grpc/grpc-go/issues/8573)) - Special Thanks: [@hugehoo](https://github.com/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](https://github.com/grpc/grpc-go/issues/8610)) - mem: Clear large buffers before re-using. ([#8670](https://github.com/grpc/grpc-go/issues/8670)) ### Performance Improvements - transport: Reduce heap allocations to reduce time spent in garbage collection.

Fallback support can no longer be disabled. ([#8482](https://github.com/grpc/grpc-go/issues/8482)) - stats: Introduce `DelayedPickComplete` event, a type alias of `PickerUpdated`. ([#8465](https://github.com/grpc/grpc-go/issues/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](https://github.com/grpc/grpc-go/issues/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](https://github.com/grpc/grpc-go/issues/8438)) - server: Return status code INTERNAL when a client sends more than one request in unary and server streaming RPC. ([#8385](https://github.com/grpc/grpc-go/issues/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](https://github.com/grpc/grpc-go/issues/8377)) ### Bug Fixes - xds: Fix regression preventing empty node IDs in xDS bootstrap configuration.

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](https://github.com/grpc/grpc-go/issues/8283)) ### API Changes - balancer: add `ExitIdle` method to `Balancer` interface. Earlier, implementing this method was optional. ([#8367](https://github.com/grpc/grpc-go/issues/8367)) ### Behavior Changes - xds: Remove the `GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST` environment variable that allows disabling the least request balancer with xDS.

([#8528](https://github.com/grpc/grpc-go/pull/8528)) ### [`v1.73.0`](https://github.com/grpc/grpc-go/releases/tag/v1.73.0): Release 1.73.0 [Compare Source](https://github.com/grpc/grpc-go/compare/v1.72.3...v1.73.0) ### New Features - balancer/ringhash: move LB policy from xds/internal to exported path to facilitate use without xds ([#8249](https://github.com/grpc/grpc-go/issues/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](https://github.com/grpc/grpc-go/issues/8253)) - grpc: add a `CallAuthority` Call Option that can be used to overwrite the http `:authority` header on per-RPC basis. ([#8068](https://github.com/grpc/grpc-go/issues/8068)) - stats/opentelemetry: add trace event for name resolution delay. ([#8074](https://github.com/grpc/grpc-go/issues/8074)) - health: added `List` method to gRPC Health service.

([#8256](https://github.com/grpc/grpc-go/issues/8256)) - client: fail RPCs on the client when using extremely short contexts that expire before the `grpc-timeout` header is created. ([#8312](https://github.com/grpc/grpc-go/issues/8312)) - server: non-positive `grpc-timeout` header values are now rejected. This is consistent with the [gRPC protocol spec](https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md#requests). ([#8290](https://github.com/grpc/grpc-go/issues/8290)) - Special Thanks: [@evanj](https://github.com/evanj) - xds: fix reported error string when LRS load reporting interval is invalid.

([#8159](https://github.com/grpc/grpc-go/issues/8159)) - pickfirst: The new pick first LB policy is made the default. The new LB policy implements the [Happy Eyeballs algorithm](https://github.com/grpc/proposal/blob/master/A61-IPv4-IPv6-dualstack-backends.md#happy-eyeballs-in-the-pick_first-lb-policy). To disable the new policy set the environment variable `GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST` to `false` (case insensitive). ### Bug Fixes - xds: fix support for circuit breakers and load reporting in LOGICAL\_DNS clusters ([#8169](https://github.com/grpc/grpc-go/issues/8169), [#8170](https://github.com/grpc/grpc-go/issues/8170)) - xds/cds: improve RPC error messages when resources are not found ([#8122](https://github.com/grpc/grpc-go/issues/8122)) - balancer/priority: fix race that could leak balancers and goroutines during shutdown ([#8095](https://github.com/grpc/grpc-go/issues/8095)) - stats/opentelemetry: fix trace attributes message sequence numbers to start from 0 ([#8237](https://github.com/grpc/grpc-go/issues/8237)) - balancer/pickfirstleaf: fix panic if deprecated Address.Metadata field is set to a non-comparable value by ignoring the field ([#8227](https://github.com/grpc/grpc-go/issues/8227)) ### Behavior Changes - transport: make servers send an HTTP/2 RST\_STREAM frame to cancel a stream when the deadline expires ([#8071](https://github.com/grpc/grpc-go/issues/8071)) ### Documentation - stats: clarify the expected sequence of events on a stats handler ([#7885](https://github.com/grpc/grpc-go/issues/7885)) - Special Thanks: [@RyanBlaney](https://github.com/RyanBlaney) ### [`v1.71.3`](https://github.com/grpc/grpc-go/releases/tag/v1.71.3): Release 1.71.3 [Compare Source](https://github.com/grpc/grpc-go/compare/v1.71.2...v1.71.3) ### Bug Fixes - client: restore support for `NO_PROXY` environment variable when connecting to locally-resolved addresses (case 2 from [gRFC A1](https://github.com/grpc/proposal/blob/master/A1-http-connect-proxy-support.md)).

This could result in a panic with the built-in gzip compressor ([#8178](https://github.com/grpc/grpc-go/issues/8178)) - xds: restore the behavior of reading the bootstrap config before creating the first xDS client instead of at package init time ([#8164](https://github.com/grpc/grpc-go/issues/8164)) - stats/opentelemetry: use `TextMapPropagator` and `TracerProvider` from `TraceOptions` instead of OpenTelemetry globals ([#8166](https://github.com/grpc/grpc-go/issues/8166)) - client: fix races when an http proxy is configured that could lead to deadlocks or panics ([#8195](https://github.com/grpc/grpc-go/issues/8195)) - client: fix bug causing RPC failures with message "no children to pick from" when using a custom resolver that calls the deprecated `NewAddress` API ([#8149](https://github.com/grpc/grpc-go/issues/8149)) - wrr: fix slow processing of address updates that could result in problems including RPC failures for servers with a large number of backends ([#8179](https://github.com/grpc/grpc-go/issues/8179)) ### [`v1.71.0`](https://github.com/grpc/grpc-go/releases/tag/v1.71.0): Release 1.71.0 [Compare Source](https://github.com/grpc/grpc-go/compare/v1.70.0...v1.71.0) ### API Changes - balancer: Custom LB policies that record metrics must use the new `MetricsRecorder` method on `Balancer.ClientConn` instead of the removed `Balancer.BuildOptions.MetricsRecorder` field to obtain a metrics recorder. ([#8027](https://github.com/grpc/grpc-go/issues/8027)) - balancer: `balancer.ClientConn` implementations must now embed a delegate implementation. This allows grpc-go to add new methods to the interface and remain backward compatible. ([#8026](https://github.com/grpc/grpc-go/issues/8026)) - balancer/endpointsharding: The constructor accepts the child balancer's builder and a struct with optional configuration. ([#8052](https://github.com/grpc/grpc-go/issues/8052)) ### New Features - xds: Add support for dualstack via the [additional\_addresses](https://github.com/envoyproxy/envoy/blob/df394a41c8587d1da4e97e156554e93ceee3c720/api/envoy/config/endpoint/v3/endpoint_components.proto#L91-L96) field in the Endpoint resource.

([#8134](https://github.com/grpc/grpc-go/issues/8134)) - stats/opentelemetry: Add experimental support for OpenTelemetry tracing. ([#7852](https://github.com/grpc/grpc-go/issues/7852)) - xds/internal/xdsclient: Add counter metrics for valid and invalid resource updates. ([#8038](https://github.com/grpc/grpc-go/issues/8038)) - balancer/leastrequest, roundrobin: Add dualstack support. ([#7969](https://github.com/grpc/grpc-go/issues/7969), [#7966](https://github.com/grpc/grpc-go/issues/7966)) - balancer/endpointsharding: Balancers created with the new `DisableAutoReconnect` option will not attempt to call `ExitIdle` automatically on their children when the children report idle. ([#8052](https://github.com/grpc/grpc-go/issues/8052)) ### Bug Fixes - client: Fix support for proxies when using `grpc.NewClient` so the target is resolved by the proxy as expected. ([#7881](https://github.com/grpc/grpc-go/issues/7881)) - Added `WithLocalDNSResolution()` dial option to explicitly force target resolution on the client instead. ([#7881](https://github.com/grpc/grpc-go/issues/7881)) - weightedtarget: Return erroring picker when no targets are configured. ([#8070](https://github.com/grpc/grpc-go/issues/8070)) - xds: Fail RPCs with `UNAVAILABLE` when the EDS resource is missing or contains no endpoints ([#8070](https://github.com/grpc/grpc-go/issues/8070)) - xdsclient: Fix a bug where connectivity failures were reported to resource watchers before trying all listed servers. ([#8075](https://github.com/grpc/grpc-go/issues/8075)) - grpc: Fix the number of bytes reported in the error message when encoded messages are larger than 4GB. ([#8033](https://github.com/grpc/grpc-go/issues/8033)) - xds: Fixed a bug preventing tests from creating multiple servers or channels with different bootstrap configs. ([#8050](https://github.com/grpc/grpc-go/issues/8050)) - grpc: Fix message length checks when compression is enabled and `maxReceiveMessageSize` is `MaxInt` ([#7918](https://github.com/grpc/grpc-go/issues/7918)) - Special Thanks: [@vinothkumarr227](https://github.com/vinothkumarr227) ### Documentation - client: Improve documentation of `grpc.NewClient` and `ClientConn.CanonicalTarget` by providing examples. ([#8078](https://github.com/grpc/grpc-go/issues/8078)) - examples/features/dualstack: New example demonstrating usage of endpoints and dualstack functionality. ([#8098](https://github.com/grpc/grpc-go/issues/8098)) ### [`v1.70.0`](https://github.com/grpc/grpc-go/releases/tag/v1.70.0): Release 1.70.0 [Compare Source](https://github.com/grpc/grpc-go/compare/v1.69.4...v1.70.0) ### Behavior Changes - client: reject service configs containing an invalid retryPolicy in accordance with gRFCs [A21](https://github.com/grpc/proposal/blob/master/A21-service-config-error-handling.md) and [A6](https://github.com/grpc/proposal/blob/master/A6-client-retries.md). ([#7905](https://github.com/grpc/grpc-go/issues/7905)) - Note that this is a potential breaking change for some users using an invalid configuration, but continuing to allow this behavior would violate our cross-language compatibility requirements. ### New Features - xdsclient: fallback to a secondary management server (if specified in the bootstrap configuration) when the primary is down is enabled by default. Can be disabled by setting the environment variable `GRPC_EXPERIMENTAL_XDS_FALLBACK` to `false`. ([#7949](https://github.com/grpc/grpc-go/issues/7949)) - experimental/credentials: experimental transport credentials are added which don't enforce ALPN. ([#7980](https://github.com/grpc/grpc-go/issues/7980)) - These credentials will be removed in an upcoming grpc-go release. Users must not rely on these credentials directly. Instead, they should either vendor a specific version of gRPC or copy the relevant credentials into their own codebase if absolutely necessary. ### Bug Fixes - xds: fix a possible deadlock that happens when both the client application and the xDS management server (responsible for configuring the client) are using the xds\:/// scheme in their target URIs. ([#8011](https://github.com/grpc/grpc-go/issues/8011)) ### Performance - server: for unary requests, free raw request message data as soon as parsing is finished instead of waiting until the method handler returns. ([#7998](https://github.com/grpc/grpc-go/issues/7998)) - Special Thanks: [@lqs](https://github.com/lqs) ### Documentation - examples/features/gracefulstop: add example to demonstrate server graceful stop.
