But merely binding to an unauthorized server to learn its UID can enable "keep-alive" and "background activity launch" abuse, even if security policy ultimately causes the grpc connection to fail. Pre-authorization mitigates this kind of abuse by resolving addresses and authorizing a candidate server Application's UID before binding to it. Pre-auth is especially important when the server's address is not fixed in advance but discovered by PackageManager lookup. ##### Bug Fixes - core: `grpc-timeout` should always be positive ([#​12201](https://redirect.github.com/grpc/grpc-java/issues/12201)) ([`6dfa03c`](https://redirect.github.com/grpc/grpc-java/commit/6dfa03c51)). There is a local race between when the deadline is checked before sending the RPC and when the timeout is calculated to put on-the-wire. The code replaced negative timeouts with 0 nanoseconds. gRPC’s PROTOCOL-HTTP2 spec states that timeouts should be positive, so now non-positive values are replaced with 1 nanosecond - core: Improved DEADLINE\_EXCEEDED message for delayed calls ([`6ff8eca`](https://redirect.github.com/grpc/grpc-java/commit/6ff8ecac0)). Delayed calls are the first calls on a Channel before name resolution has resolved addresses. Previously you could see confusing errors saying the deadline “will be exceeded in” X time. The message tense was simply wrong, and now will be correct: deadline “was exceeded after” X time. - xds: PriorityLB now only uses the failOverTimer to start additional priorities, not fail RPCs ([`c4256ad`](https://redirect.github.com/grpc/grpc-java/commit/c4256add4)). You should no longer see “Connection timeout for priority” errors. ##### Improvements - netty: Count sent RST\_STREAMs against `NettyServerBuilder.maxRstFramesPerWindow()` limit ([#​12288](https://redirect.github.com/grpc/grpc-java/issues/12288)). This extends the Rapid Reset tool to also cover MadeYouReset. the reset stream count will cause a 420 "Enhance your calm response" to be sent. This depends on Netty 4.1.124 for a bug fix to actually call the encoder by the frame writer. - xds: Convert CdsLb to `XdsDepManager` ([`297ab05`](https://redirect.github.com/grpc/grpc-java/commit/297ab05ef)). This is part of gRFC A74 to have atomic xDS config updates. This is an internal change, but does change the error description seen in certain cases, especially DEADLINE\_EXCEEDED on a brand-new channel. - census: APIs for stats and tracing ([#​12050](https://redirect.github.com/grpc/grpc-java/issues/12050)) ([`9193701`](https://redirect.github.com/grpc/grpc-java/commit/919370172)). Client channel and server builders with interceptors and factories respectively for stats and tracing. - stub: simplify `BlockingClientCall` infinite blocking ([#​12217](https://redirect.github.com/grpc/grpc-java/issues/12217)) ([`ba0a732`](https://redirect.github.com/grpc/grpc-java/commit/ba0a7329d)). Move deadline computation into overloads with finite timeouts. Blocking calls without timeouts now do not have to read the clock. - xds: Do RLS fallback policy eagar start ([#​12211](https://redirect.github.com/grpc/grpc-java/issues/12211)) ([`42e1829`](https://redirect.github.com/grpc/grpc-java/commit/42e1829b3)). In gRPC-Java, the xDS clusters were lazily subscribed, which meant the fallback target which is returned in the RLS config wasn’t subscribed until a RPC actually falls back to it. The delayed resource subscription process in gRPC Java made it more susceptible to the effects of the INITIAL\_RESOURCE\_FETCH\_TIMEOUT compared to other programming languages. It also had impact beyond the RLS cache expiration case, for example, when the first time the client initialized the channel, we couldn't fallback when the intended target times out, because of the lazy subscription. This change starts the fallback LB policy for the default target at the start of RLS policy instead of only when falling back to the default target, which fixes the above mentioned problems. - xds: Aggregate cluster fixes (A75) ([#​12186](https://redirect.github.com/grpc/grpc-java/issues/12186)) ([`7e982e4`](https://redirect.github.com/grpc/grpc-java/commit/7e982e48a)). The earlier implementation of aggregate clusters concatenated the priorities from the underlying clusters into a single list, so that it could use a single LB policy defined at the aggregate cluster layer to choose a priority from that combined list. However, it turns out that aggregate clusters don't actually define the LB policy in the aggregate cluster; instead, the aggregate cluster uses a special cluster-provided LB policy that first chooses the underlying cluster and then delegates to the LB policy of the underlying cluster. This change implements that. - api: set size correctly for sets and maps in handling `Metadata` values to be exchanged during a call ([#​12229](https://redirect.github.com/grpc/grpc-java/issues/12229)) ([`8021727`](https://redirect.github.com/grpc/grpc-java/commit/80217275d)) - xds: xdsClient cache transient error for new watchers ([#​12291](https://redirect.github.com/grpc/grpc-java/issues/12291)). When a resource update is NACKed, cache the error and update new watchers that get added with that error instead of making them hang. - xds: Avoid PriorityLb re-enabling timer on duplicate CONNECTING ([#​12289](https://redirect.github.com/grpc/grpc-java/issues/12289)). If a LB policy gives extraneous updates with state CONNECTING, then it was possible to re-create `failOverTimer` which would then wait the 10 seconds for the child to finish CONNECTING. We only want to give the child one opportunity after transitioning out of READY/IDLE. - xds: Use a different log name for `XdsClientImpl` and `ControlPlaneClient` ([#​12287](https://redirect.github.com/grpc/grpc-java/issues/12287)). `ControlPlaneClient` uses "xds-cp-client" now instead of "xds-client" while logging. ##### Dependencies Changes - Upgrade to Netty 4.1.124.Final ([#​12286](https://redirect.github.com/grpc/grpc-java/issues/12286)). This implicitly disables `NettyAdaptiveCumulator` ([#​11284](https://redirect.github.com/grpc/grpc-java/issues/11284)), which can have a performance impact. We delayed upgrading Netty to give time to rework the optimization, but we've gone too long already without upgrading which causes problems for vulnerability tracking. - bazel: Use `jar_jar` to avoid xds deps ([#​12243](https://redirect.github.com/grpc/grpc-java/issues/12243)) ([`8f09b96`](https://redirect.github.com/grpc/grpc-java/commit/8f09b9689)). The //xds and //xds:orca targets now use `jar_jar` to shade the protobuf generated code. This allows them to use their own private copy of the protos and drop direct Bazel dependencies on cel-spec, grpc, rules\_go, com\_github\_cncf\_xds, envoy\_api, com\_envoyproxy\_protoc\_gen\_validate, and opencensus\_proto. This mirrors the shading of protobuf messages done for grpc-xds provided on Maven Central and should simplify dependency management ##### Documentation - Clarify requirements for creating a cross-user Channel. ([#​12181](https://redirect.github.com/grpc/grpc-java/issues/12181)). The `@SystemApi` runtime visibility requirement isn't really new. It has always been implicit in the required INTERACT\_ACROSS\_USERS permission, which can only be held by system apps in production. Now deprecated `BinderChannelBuilder#bindAsUser` has always required SDK\_INT >= 30. This change just copies that requirement forward to its replacement APIs in `AndroidComponentAddress` and the TARGET\_ANDROID\_USER `NameResolver.Args`. - api: Add more Javadoc for `NameResolver.Listener2` interface ([#​12220](https://redirect.github.com/grpc/grpc-java/issues/12220)) ([`d352540`](https://redirect.github.com/grpc/grpc-java/commit/d352540a0)) ##### Thanks to [@​benjaminp](https://redirect.github.com/benjaminp) [@​werkt](https://redirect.github.com/werkt) [@​kilink](https://redirect.github.com/kilink) [@​vimanikag](https://redirect.github.com/vimanikag) ### [`v1.74.0`](https://redirect.github.com/grpc/grpc-java/releases/tag/v1.74.0) ##### Behavior Changes - compiler: Default to `@generated=omit` ([`f8700a1`](https://redirect.github.com/grpc/grpc-java/commit/f8700a13a)). This omits `javax.annotation.Generated` from the generated code and makes the `org.apache.tomcat:annotations-api` compile-only dependency unnecessary (README and examples changes forthcoming; we delayed those changes until the release landed). You can use the option `@generated=javax` for the previous behavior, but please also file an issue so we can develop alternatives - compiler: generate blocking v2 unary calls that throw StatusException ([#​12126](https://redirect.github.com/grpc/grpc-java/issues/12126)) ([`a16d655`](https://redirect.github.com/grpc/grpc-java/commit/a16d65591)). Previously, the new blocking stub API was identical to the older blocking stub for unary RPCs and used the unchecked `StatusRuntimeException`. However, feedback demonstrated it was confusing to mix that with the checked `StatusException` in `BlockingClientCall`. Now the new blocking stub uses StatusException throughout. grpc-java continues to support the old generated code, but the version of protoc-gen-grpc-java will dictate which API you see. If you support multiple generated code versions, you can use the older blocking v1 stub for unary RPCs ##### Bug Fixes - netty: Fix a race that caused RPCs to hang on start when a GOAWAY was received while the RPCs’ headers were being written to the OS ([`b04c673`](https://redirect.github.com/grpc/grpc-java/commit/b04c673fd), [`15c7573`](https://redirect.github.com/grpc/grpc-java/commit/15c757398)). This was a very old race, not a recent regression. All streams should now properly fail instead of hanging, although in some cases they may be transparently retried - util: OutlierDetection should use nanoTime, not currentTimeMillis ([#​12110](https://redirect.github.com/grpc/grpc-java/issues/12110)) ([`1c43098`](https://redirect.github.com/grpc/grpc-java/commit/1c4309899)). Previously, changes in the wall time would impact its accounting - xds: Don't allow hostnames in address field in EDS ([#​12123](https://redirect.github.com/grpc/grpc-java/issues/12123)) ([`482dc5c`](https://redirect.github.com/grpc/grpc-java/commit/482dc5c1c)). Only IP addresses were handled properly, and only IP addresses should be handled per gRFC A27 - xds: In resource handling, call onError() for RDS and EDS NACKs ([#​12122](https://redirect.github.com/grpc/grpc-java/issues/12122)) ([`efe9ccc`](https://redirect.github.com/grpc/grpc-java/commit/efe9ccc22)). Previously the resource was NACKed, but gRPC would continue waiting for the resource until a timeout was reached and claim the control plane didn’t send the resource. Now it will fail quickly with an informative error - xds: Implement equals in RingHashConfig ([`a5eaa66`](https://redirect.github.com/grpc/grpc-java/commit/a5eaa66cc)). Previously all configuration refreshes were considered a new config, which had the potential for causing unexpected inefficiency problems. This was noticed by new code for gRFC A74 xDS Config Tears that is not yet enabled, so there are no known problems that this caused - LBs should avoid calling LBs after lb.shutdown() ([`1df2a33`](https://redirect.github.com/grpc/grpc-java/commit/1df2a3305)). This fixed pick\_first and ring\_hash behavior that could cause rare and “random” races in parent load balancers like a `NullPointerException` in `ClusterImplLoadBalancer.createSubchannel()`, which had a ring\_hash child. This is most likely to help xDS, as it heavily uses hierarchical LB policies ##### Improvements - util: Deliver addresses in a random order to shuffle connection creation ordering ([`f07eb47`](https://redirect.github.com/grpc/grpc-java/commit/f07eb47ca)). Previously, connections were created in-order (but non-blocking), so in a fast network the first address could be more likely to connect first given a "microsecond" headstart. That first connection then receives all the buffered RPCs, which could cause temporary, but repeated, load imbalances of the same backend when all clients receive the same list of addresses in the same order. This has been seen in practice, but it is unclear how often it happens. Shuffling has the potential to improve load distribution of new clients when using round\_robin, weighted\_round\_robin, and least\_request, which connect simultaneously to multiple addresses - core: Use lazy message formatting in checkState ([#​12144](https://redirect.github.com/grpc/grpc-java/issues/12144)) ([`26bd0ee`](https://redirect.github.com/grpc/grpc-java/commit/26bd0eee4)). This avoids the potential of unnecessarily formatting an exception as a string when a subchannel fails to connect - bazel: Migrate java\_grpc\_library to use DefaultInfo ([#​12148](https://redirect.github.com/grpc/grpc-java/issues/12148)) ([`6f69363`](https://redirect.github.com/grpc/grpc-java/commit/6f69363d9)). This adds compatibility for `--incompatible_disable_target_default_provider_fields` - binder: Rationalize [@​ThreadSafe-ty](https://redirect.github.com/ThreadSafe-ty) inside BinderTransport ([#​12130](https://redirect.github.com/grpc/grpc-java/issues/12130)) ([`c206428`](https://redirect.github.com/grpc/grpc-java/commit/c20642874)) - binder: Cancel checkAuthorization() request if still pending upon termination ([#​12167](https://redirect.github.com/grpc/grpc-java/issues/12167)) ([`30d40a6`](https://redirect.github.com/grpc/grpc-java/commit/30d40a617)) ##### Dependencies - compiler: Upgrade Protobuf C++ to 22.5 ([#​11961](https://redirect.github.com/grpc/grpc-java/issues/11961)) ([`46485c8`](https://redirect.github.com/grpc/grpc-java/commit/46485c8b6)). This is used by the pre-built protoc-gen-grpc-java plugin on Maven Central. This should have no visible benefit, but gets us closer to upgrading to Protobuf 27 which added edition 2023 support - release: Migrate artifacts publishing changed from legacy OSSRH to Central Portal ([#​12156](https://redirect.github.com/grpc/grpc-java/issues/12156)) ([`f99b2aa`](https://redirect.github.com/grpc/grpc-java/commit/f99b2aaef)). We aren’t aware of any visible changes to the results on Maven Central ### [`v1.73.0`](https://redirect.github.com/grpc/grpc-java/releases/tag/v1.73.0) ##### API Changes xds: Enable least request by default ([#​12062](https://redirect.github.com/grpc/grpc-java/issues/12062)) core: Delete the long-deprecated GRPC\_PROXY\_EXP env variable ([#​11988](https://redirect.github.com/grpc/grpc-java/issues/11988)) ([`908f9f1`](https://redirect.github.com/grpc/grpc-java/commit/908f9f19c)). This was experimental and has been warning when used since v1.8.0. Use the Java-standard -Dhttps.proxyHost and -Dhttps.proxyPort instead api: Remove deprecated SubchannelPicker.requestConnection() ([`f79ab2f`](https://redirect.github.com/grpc/grpc-java/commit/f79ab2f16)). This API was replaced by LoadBalancer.requestConnection() in v1.22.0 ##### Bug Fixes config: prevents global stats config freeze in ConfiguratorRegistry.getConfigurators() ([#​11991](https://redirect.github.com/grpc/grpc-java/issues/11991)) ([`d4c46a7`](https://redirect.github.com/grpc/grpc-java/commit/d4c46a7f1)) xds: XdsDepManager should ignore updates after shutdown ([`25199e9`](https://redirect.github.com/grpc/grpc-java/commit/25199e9df)). This fixes a source of java.lang.NullPointerException: Cannot invoke "io.grpc.xds.XdsDependencyManager$RdsUpdateSupplier.getRdsUpdate()" because "routeSource" is null regression introduced in v1.72.0 ##### Improvements xds: listener type validation ([#​11933](https://redirect.github.com/grpc/grpc-java/issues/11933)) ([`c8d1e6e`](https://redirect.github.com/grpc/grpc-java/commit/c8d1e6e39)) xds: add the missing xds.authority metric defined in [gRFC A78](https://redirect.github.com/grpc/proposal/blob/master/A78-grpc-metrics-wrr-pf-xds.md#xdsclient) ([#​12018](https://redirect.github.com/grpc/grpc-java/issues/12018)) ([`6cd007d`](https://redirect.github.com/grpc/grpc-java/commit/6cd007d0d)) ##### New Features xds: float LRU cache across interceptors ([#​11992](https://redirect.github.com/grpc/grpc-java/issues/11992)) ([`7a08fdb`](https://redirect.github.com/grpc/grpc-java/commit/7a08fdb7f)) xds: propagate audience from cluster resource in gcp auth filter. This completes the gRFC A83, implementation of GCP Authentication Filter. ([#​11972](https://redirect.github.com/grpc/grpc-java/issues/11972)) ([`84c7713`](https://redirect.github.com/grpc/grpc-java/commit/84c7713b2)) opentelemetry: Implement grpc.lb.backend\_service optional label ([`9619453`](https://redirect.github.com/grpc/grpc-java/commit/961945379)). This completes the [gRFC A89](https://redirect.github.com/grpc/proposal/blob/master/A89-backend-service-metric-label.md) implementation, which is enabled when requesting the new label ##### Documentation api: Remove mention of "epoch" from Ticker.nanoTime() javadocs ([`84bd014`](https://redirect.github.com/grpc/grpc-java/commit/84bd01454)) ### [`v1.72.0`](https://redirect.github.com/grpc/grpc-java/releases/tag/v1.72.0) ##### API Changes - util: Remove deprecated method GracefulSwitchLb.switchTo() ([`f207be3`](https://redirect.github.com/grpc/grpc-java/commit/f207be39a)). It is rarely used outside of gRPC itself. The configuration is passed as lb policy configuration instead - xds: Add support for custom per-target credentials on the transport ([#​11951](https://redirect.github.com/grpc/grpc-java/issues/11951)) ([`1958e42`](https://redirect.github.com/grpc/grpc-java/commit/1958e4237)) - xds: Explicitly set request hash key for the ring hash LB policy ([`892144d`](https://redirect.github.com/grpc/grpc-java/commit/892144dca)) ##### Bug Fixes - core: Apply ManagedChannelImpl's updateBalancingState() immediately ([`ca4819a`](https://redirect.github.com/grpc/grpc-java/commit/ca4819ac6)) - xds: Fix cluster selection races when updating config selector ([`d82613a`](https://redirect.github.com/grpc/grpc-java/commit/d82613a74)) - otel: Fix span names as per the A72 gRFC changes ([#​11974](https://redirect.github.com/grpc/grpc-java/issues/11974)) ([`94f8e93`](https://redirect.github.com/grpc/grpc-java/commit/94f8e9369)) - xds: ClusterResolverLoadBalancer handle update for both resolved addresses and errors via ResolutionResult ([#​11997](https://redirect.github.com/grpc/grpc-java/issues/11997)) ([`8681786`](https://redirect.github.com/grpc/grpc-java/commit/868178651)) ##### Improvements - netty: Avoid allocating an exception on transport shutdown. This reduces allocation rate for connection-heavy workloads/load testing ([`a57c14a`](https://redirect.github.com/grpc/grpc-java/commit/a57c14a51)) - servlet: Set an explicit description for CANCELLED status ([#​11927](https://redirect.github.com/grpc/grpc-java/issues/11927)) ([`fca1d3c`](https://redirect.github.com/grpc/grpc-java/commit/fca1d3cf4)) - xds: [gRFC A74 xDS Config Tears](https://redirect.github.com/grpc/proposal/blob/master/A74-xds-config-tears.md) implementation in the XdsNameResolver ([`e80c197`](https://redirect.github.com/grpc/grpc-java/commit/e80c19745)). While there is more remaining, users may already see reduced latency when resources are replaced. For example, if changing a route from one backend service to another, RPCs may see less latency during the transition - core: Log any exception during channel panic because of exception ([`3961a92`](https://redirect.github.com/grpc/grpc-java/commit/3961a923a)). This prevents the exception from propagating up the stack on an arbitrary thread. Such exceptions are rarely interesting. Instead, the exception that caused the channel panic is the important one, and RPCs will still fail with its details - util: Graceful switch to new LB when leaving CONNECTING ([`2e260a4`](https://redirect.github.com/grpc/grpc-java/commit/2e260a4bb)). Previously when using xDS and the configuration changes the LB policy, the old LB policy is used until the new one is READY. Now the old LB policy is used until the new policy becomes READY, TRANSIENT\_FAILURE, or IDLE - core: Use java.time.Time.getNano directly in InstantTimeProvider. Previously reflection was used which would confuse R8 full mode ([#​11977](https://redirect.github.com/grpc/grpc-java/issues/11977)) ([`7507a9e`](https://redirect.github.com/grpc/grpc-java/commit/7507a9ec0)) - core: Avoid cancellation exceptions when notifying watchers that already have their connections cancelled ([#​11934](https://redirect.github.com/grpc/grpc-java/issues/11934)) ([`350f90e`](https://redirect.github.com/grpc/grpc-java/commit/350f90e1a)) - rls: allow maxAge in RLS config to exceed 5 minutes if staleAge is set. Previously, the limit was 5 minutes, which isn't enough for some gRPC clients ([#​11931](https://redirect.github.com/grpc/grpc-java/issues/11931)) ([`c340f4a`](https://redirect.github.com/grpc/grpc-java/commit/c340f4a2f)) - xds: avoid unnecessary dns lookup for CIDR addresses ([#​11932](https://redirect.github.com/grpc/grpc-java/issues/11932)) ([`602aece`](https://redirect.github.com/grpc/grpc-java/commit/602aece08)) - netty: Swap to UniformStreamByteDistributor ([#​11954](https://redirect.github.com/grpc/grpc-java/issues/11954)) ([`2f52a00`](https://redirect.github.com/grpc/grpc-java/commit/2f52a0036)). gRPC will no longer observe the HTTP/2 priorities, which were not used directly by gRPC and deprecated in RFC 9113 - core: Avoid Set.removeAll() when passing a possibly-large List ([#​11994](https://redirect.github.com/grpc/grpc-java/issues/11994)) ([`666136b`](https://redirect.github.com/grpc/grpc-java/commit/666136b4b)) - stub: trailersFromThrowable() metadata should be copied ([#​11979](https://redirect.github.com/grpc/grpc-java/issues/11979)) ([`a6e1c1f`](https://redirect.github.com/grpc/grpc-java/commit/a6e1c1f09)) ##### New Features - xds: xDS-based HTTP CONNECT configuration ([#​11861](https://redirect.github.com/grpc/grpc-java/issues/11861)) ([`1219706`](https://redirect.github.com/grpc/grpc-java/commit/12197065f)) - netty: Per-rpc authority verification against peer cert subject names. Overriding transport authority at rpc time is only allowed when using TlsChannelCredentials. The per-rpc authority verification feature is guarded by the environment variable GRPC\_ENABLE\_PER\_RPC\_AUTHORITY\_CHECK in this release. When this is false or not set, the rpc will not fail when the authority verification fails but a warning will be logged. In a subsequent release the usage of this environment variable will be removed and RPCs will start failing if the authority doesn't match the peer certificate names. The environment variable is temporary; if you are depending on the existing insecure behavior, please file an issue ([#​11724](https://redirect.github.com/grpc/grpc-java/issues/11724)) ([`cdab410`](https://redirect.github.com/grpc/grpc-java/commit/cdab410b8)) ##### Thanks to [@​panchenko](https://redirect.github.com/panchenko) [@​emmanuel-ferdman](https://redirect.github.com/emmanuel-ferdman) [@​JoeCqupt](https://redirect.github.com/JoeCqupt) ### [`v1.71.0`](https://redirect.github.com/grpc/grpc-java/releases/tag/v1.71.0) ##### API Changes - xds: Enable Xds Client Fallback by default. This allows having a backup xDS server as described in gRFC [A71-xds-fallback.md](https://redirect.github.com/grpc/proposal/blob/master/A71-xds-fallback.md) ([#​11817](https://redirect.github.com/grpc/grpc-java/issues/11817)) ([`176f3ee`](https://redirect.github.com/grpc/grpc-java/commit/176f3eed1)) - protobuf: Experimental API marshallerWithRecursionLimit in `ProtoUtils` is now stabilized ([#​11884](https://redirect.github.com/grpc/grpc-java/issues/11884)) ([`90b1c4f`](https://redirect.github.com/grpc/grpc-java/commit/90b1c4fe9)) ##### Bug Fixes - xds: Cluster weights should be uint32 ([`199a7ea`](https://redirect.github.com/grpc/grpc-java/commit/199a7ea3e)). They were previously processed as int32, although the sum of weights was checked to be positive. So this would have caused a very large weight to never be selected and to reduce the chances of immediately-following clusters to be selected. There have been no reports of control planes using such large weights - xds: Fix an unlikely infinite loop triggered by route update ([`199a7ea`](https://redirect.github.com/grpc/grpc-java/commit/199a7ea3e)). Triggering required the old cluster to no longer be used, an RPC processing when the update arrived, and for a RPC to not match any route in the new config. There have been no reports of this actually happening - core: Release data frame if it is received before the headers ([`dc316f7`](https://redirect.github.com/grpc/grpc-java/commit/dc316f7fd)) ##### Improvements - Replace jsr305's `CheckReturnValue` with Error Prone's ([#​11811](https://redirect.github.com/grpc/grpc-java/issues/11811)) ([`7b5d069`](https://redirect.github.com/grpc/grpc-java/commit/7b5d0692c)) - core: optimize number of buffer allocations for message sizes larger than 1 MB ([#​11879](https://redirect.github.com/grpc/grpc-java/issues/11879)) ([`5a7f350`](https://redirect.github.com/grpc/grpc-java/commit/5a7f35053)) - core: Update the retry backoff range from \[0, 1] to \[0.8, 1.2] as per the A6 redefinition ([#​11858](https://redirect.github.com/grpc/grpc-java/issues/11858)) ([`44e92e2`](https://redirect.github.com/grpc/grpc-java/commit/44e92e2c2)) - core: include last pick status in status message when wait-for-ready RPC’s deadline expires ([#​11851](https://redirect.github.com/grpc/grpc-java/issues/11851)) ([`7585b16`](https://redirect.github.com/grpc/grpc-java/commit/7585b1607)).

Violations would only have triggered on API level 23 and earlier, and the violations fixed here were highly unlikely to be triggered - api: Fix Android API level 23 and earlier compatibility for StatusRuntimeException without stacktrace ([#​11072](https://redirect.github.com/grpc/grpc-java/issues/11072)) ([`ebe2b48`](https://redirect.github.com/grpc/grpc-java/commit/ebe2b4867)). This fixes a regression introduced in 1.64.0. The regression should have caused failures on API level 23 and earlier when a StatusRuntimeException or StatusException was created. However, for unknown reasons tests on old devices didn’t notice issues - okhttp: Improve certificate handling by rejecting non-ASCII subject alternative names and hostnames as seen in CVE-2021-0341 ([#​11749](https://redirect.github.com/grpc/grpc-java/issues/11749)) ([`a0982ca`](https://redirect.github.com/grpc/grpc-java/commit/a0982ca0a)). Hostnames are considered trusted and CAs are required to use punycode for non-ASCII hostnames, so this is expected to provide defense-in-depth. See also the [related GoSecure blog post](https://gosecure.ai/blog/2020/10/27/weakness-in-java-tls-host-verification/) and the [AOSP fix](https://android.googlesource.com/platform/external/okhttp/+/ddc934efe3ed06ce34f3724d41cfbdcd7e7358fc) - okhttp: Fix for ipv6 link local with scope ([#​11725](https://redirect.github.com/grpc/grpc-java/issues/11725)) ([`65b32e6`](https://redirect.github.com/grpc/grpc-java/commit/65b32e60e)) - xds: Preserve nonce when unsubscribing last watcher of a particular type so that new discovery requests of that type are handled correctly ([`1cf1927`](https://redirect.github.com/grpc/grpc-java/commit/1cf1927d1)). This (along with [`6c12c2b`](https://redirect.github.com/grpc/grpc-java/commit/6c12c2bd2)) fixes a nonce-handling regression introduced in 1.66.0 that could cause resources to appear to not exist until re-creating the ADS stream. Triggering the behavior required specific config changes. It is easiest to trigger when clusters use EDS and routes are changed from one cluster to another. The error “found 0 leaf (logical DNS or EDS) clusters for root cluster” might then be seen - xds: Remember nonces for unknown types ([`6c12c2b`](https://redirect.github.com/grpc/grpc-java/commit/6c12c2bd2)) - xds: Unexpected types in the bootstrap’s server\_features should be ignored ([`e8ff6da`](https://redirect.github.com/grpc/grpc-java/commit/e8ff6da2c)). They were previously required to be strings - xds: Remove xds authority label from metric registration ([#​11760](https://redirect.github.com/grpc/grpc-java/issues/11760)) ([`6516c73`](https://redirect.github.com/grpc/grpc-java/commit/6516c7387)). This fixes the error “Incorrect number of required labels provided. Expected: 4” introduced in 1.69.0 - xds: Fixed unsupported unsigned 32 bits issue for circuit breaker ([#​11735](https://redirect.github.com/grpc/grpc-java/issues/11735)) ([`f8f6139`](https://redirect.github.com/grpc/grpc-java/commit/f8f613984)). This fixes clients treating large max\_requests as “no requests” and failing all requests ##### **Improvements** - api: Introduce custom NameResolver.Args ([#​11669](https://redirect.github.com/grpc/grpc-java/issues/11669)) ([`0b2d440`](https://redirect.github.com/grpc/grpc-java/commit/0b2d44098)) - stub: Introduce new API: BlockingStubV2 which supports Bidi streaming, Client streaming, a cleaner Server streaming and Unary RPCs ([#​10318](https://redirect.github.com/grpc/grpc-java/issues/10318)) ([`ea8c31c`](https://redirect.github.com/grpc/grpc-java/commit/ea8c31c30)) - bazel: Remove workaround for DoNotCall fixed in Bazel 3.4 ([`805cad3`](https://redirect.github.com/grpc/grpc-java/commit/805cad378)) - binder: A standard API for pointing resolvers at a different Android User.

Not used actively, but this adds validation. The validation is unlikely to fail but may reject invalid resources. - xds: Use "#server" as dataplane target value for xDS enabled gRPC servers ([#​11715](https://redirect.github.com/grpc/grpc-java/issues/11715)) ([`ebb43a6`](https://redirect.github.com/grpc/grpc-java/commit/ebb43a69e)). This only impacts the `grpc.target` label in `grpc.xds_client.*` metrics. Previously the empty string was used - rls: Reduce RLS debug channel logging ([`7f9c1f3`](https://redirect.github.com/grpc/grpc-java/commit/7f9c1f39f)). This only matters when debug logging is enabled ##### **Documentation** - examples: Simplify graceful shutdown in Hostname example ([`f1109e4`](https://redirect.github.com/grpc/grpc-java/commit/f1109e421)) - examples: Remove references to maven-central.storage-download.googleapis.com ([`c96e926`](https://redirect.github.com/grpc/grpc-java/commit/c96e926e6)) - examples: Updated the attachHeaders to newAttachHeadersInterceptor in HeaderClientInterceptor ([#​11759](https://redirect.github.com/grpc/grpc-java/issues/11759)) ([`5e8abc6`](https://redirect.github.com/grpc/grpc-java/commit/5e8abc677)) ##### **Dependencies** - Bazel 8 is released, so replace Bazel 6 testing with Bazel 7 ([`8a5f777`](https://redirect.github.com/grpc/grpc-java/commit/8a5f7776d)) ##### **Thanks to** - [@​panchenko](https://redirect.github.com/panchenko) - [@​benjaminp](https://redirect.github.com/benjaminp) - [@​ZachChuba](https://redirect.github.com/ZachChuba) - [@​vinodhabib](https://redirect.github.com/vinodhabib) ### [`v1.69.1`](https://redirect.github.com/grpc/grpc-java/releases/tag/v1.69.1) ##### Bug Fixes - okhttp: Improve certificate handling by rejecting non-ASCII subject alternative names and hostnames as seen in CVE-2021-0341 ([#​11749](https://redirect.github.com/grpc/grpc-java/issues/11749)) ([`a0982ca`](https://redirect.github.com/grpc/grpc-java/commit/a0982ca0a)).

Previously, the last value was used - okhttp: Detect transport executors with no remaining threads ([#​11503](https://redirect.github.com/grpc/grpc-java/issues/11503)) ([`3a6be9c`](https://redirect.github.com/grpc/grpc-java/commit/3a6be9ca1)). The transport uses two threads, but one is on-demand. If the executor provided to `builder.transportExecutor()` runs out of threads (e.g., it is a fixed-size thread pool), *all* transports can be wedged, unable to run on-demand tasks, until keepalive kills one of them. Two threads are now used when handshaking a new transport, and the transport will time out after 1 second with “Timed out waiting for second handshake thread” if two threads are unavailable - gcp-csm-o11y: Get `mesh_id` value from `CSM_MESH_ID` environment variable, instead of getting it from bootstrap file ([`84d30af`](https://redirect.github.com/grpc/grpc-java/commit/84d30afad)) ##### Improvements - New grpc-context-override-opentelemetry artifact ([#​11523](https://redirect.github.com/grpc/grpc-java/issues/11523)) ([`782a44a`](https://redirect.github.com/grpc/grpc-java/commit/782a44ad6)) ([#​11599](https://redirect.github.com/grpc/grpc-java/issues/11599)) ([`e59ae5f`](https://redirect.github.com/grpc/grpc-java/commit/e59ae5fad)). This is a `io.grpc.Context` storage override to store its state in `io.opentelemetry.context.Context`. Libraries should not add a dependency on this artifact, as applications can only have one storage override in their classpath - New grpc-s2a artifact. It is a transport that offloads the handshake similar to ALTS, but for TLS. It provides `io.grpc.s2a.S2AChannelCredentials` - api: Enhance name resolver \`ResolutionResult\` to hold addresses or error so the single listener API *onResult2* is used to convey both success and error cases for name resolution ([#​11330](https://redirect.github.com/grpc/grpc-java/issues/11330)) ([`1ded8af`](https://redirect.github.com/grpc/grpc-java/commit/1ded8aff8)) - core: Handle NameResolver/LoadBalancer exceptions when panicking ([`b692b9d`](https://redirect.github.com/grpc/grpc-java/commit/b692b9d26)). This expands the class of bugs that will fail RPCs with the panic error, versus some undefined behavior - core: Use the default service config in case of initial name resolver address resolution error ([#​11577](https://redirect.github.com/grpc/grpc-java/issues/11577)) ([`fa26a8b`](https://redirect.github.com/grpc/grpc-java/commit/fa26a8bc5)) - core: `StreamTracer.inboundMessageRead()` now reports uncompressed message size when the message does not need compression ([#​11598](https://redirect.github.com/grpc/grpc-java/issues/11598)) ([`2aae68e`](https://redirect.github.com/grpc/grpc-java/commit/2aae68e11)). Previously it always reported `-1` (unknown) - netty: Avoid TCP\_USER\_TIMEOUT warning when explicitly specifying a non-epoll channel type to use ([#​11564](https://redirect.github.com/grpc/grpc-java/issues/11564)) ([`62f4098`](https://redirect.github.com/grpc/grpc-java/commit/62f409810)) - okhttp: Don't warn about missing Conscrypt ([`6f35422`](https://redirect.github.com/grpc/grpc-java/commit/6f3542297)). This is especially helpful when using TLS but not running on Android - android: For `UdsChannelBuilder`, use fake IP instead of localhost ([`a908b5e`](https://redirect.github.com/grpc/grpc-java/commit/a908b5e40)). This avoids an unnecessary DNS lookup - xds: Add xDS node ID in select control plane errors to enable cross-referencing with control plane logs when debugging ([`f3cf7c3`](https://redirect.github.com/grpc/grpc-java/commit/f3cf7c3c7)) - xds: Enhanced how ADS stream terminations are handled, specifically addressing cases where a response has or hasn't been received (#​2e9c3e19f) - binder: Update status code documentation for Android 11's package visibility rules. ([#​11551](https://redirect.github.com/grpc/grpc-java/issues/11551)) ([`99be6e9`](https://redirect.github.com/grpc/grpc-java/commit/99be6e985)) - binder: Update binderDied() error description to spell out the possibilities for those unfamiliar with Android internals. ([#​11628](https://redirect.github.com/grpc/grpc-java/issues/11628)) ([`46c1b38`](https://redirect.github.com/grpc/grpc-java/commit/46c1b387f)) - example-gauth: Use application default creds instead of file argument ([#​11595](https://redirect.github.com/grpc/grpc-java/issues/11595)) ([`94a0a0d`](https://redirect.github.com/grpc/grpc-java/commit/94a0a0d1c)) - opentelemetry: Experimental OpenTelemetry tracing is available. Set the `GRPC_EXPERIMENTAL_ENABLE_OTEL_TRACING` environment variable to `true` to enable tracing support in `GrpcOpenTelemetry` ([#​11409](https://redirect.github.com/grpc/grpc-java/issues/11409), [#​11477](https://redirect.github.com/grpc/grpc-java/issues/11477))([`043ba55`](https://redirect.github.com/grpc/grpc-java/commit/043ba55), [`421e237`](https://redirect.github.com/grpc/grpc-java/commit/421e237)) ##### Dependencies - Updated protobuf-java to 3.25.5. This helps avoid CVE-2024-7254 ([`2ff837a`](https://redirect.github.com/grpc/grpc-java/commit/2ff837ab6)) Thanks to:\ [@​Juneezee](https://redirect.github.com/Juneezee)\ [@​lgalfaso](https://redirect.github.com/lgalfaso)\ [@​bestbeforetoday](https://redirect.github.com/bestbeforetoday)\ [@​hlx502](https://redirect.github.com/hlx502)\ [@​JoeCqupt](https://redirect.github.com/JoeCqupt) ### [`v1.68.0`](https://redirect.github.com/grpc/grpc-java/releases/tag/v1.68.0): MISTAKE This was supposed to be v1.67.0, but there was a mistake during the release process. This has everything in v1.67.1, *except* for: - xds: Fix NullPointerException introduced in "Fix load reporting when pick first is used for locality-routing" ([#​11553](https://redirect.github.com/grpc/grpc-java/pull/11553)) ### [`v1.67.1`](https://redirect.github.com/grpc/grpc-java/releases/tag/v1.67.1) ##### gRPC Java 1.67.1 Release Notes There was no 1.67.0 release. There was a problem making the release and it went to Maven Central as 1.68.0 instead. This is a version-corrected release. ##### Improvements - Petiole load balancing policies (e.g., round\_robin, weighted\_round\_robin, ring\_hash, least\_request) had internal refactorings. This should not have changed their behavior - api: Introduce onResult2 in NameResolver Listener2 that returns Status ([`90d0fab`](https://redirect.github.com/grpc/grpc-java/commit/90d0fabb1)) - core: touch() buffer when detach()ing ([`e821d5e`](https://redirect.github.com/grpc/grpc-java/commit/e821d5e15)). This makes it clearer whether a leak is a gRPC leak or an application leak when the Detachable API is being used - example: delete duplicate and unused code in KeepAliveClient.java ([`6a9bc3b`](https://redirect.github.com/grpc/grpc-java/commit/6a9bc3ba1)) - example: Added Dualstack example ([#​11451](https://redirect.github.com/grpc/grpc-java/issues/11451)) ([`72a977b`](https://redirect.github.com/grpc/grpc-java/commit/72a977bf7)) - stub: Add newAttachMetadataServerInterceptor() MetadataUtil ([#​11458](https://redirect.github.com/grpc/grpc-java/issues/11458)) ([`6dbd1b9`](https://redirect.github.com/grpc/grpc-java/commit/6dbd1b9d5)) - xds: Separate xds clients for each channel target, each with its own connection to an xds server. ([#​11484](https://redirect.github.com/grpc/grpc-java/issues/11484)) ([`d034a56`](https://redirect.github.com/grpc/grpc-java/commit/d034a56cb)) - xds: Envoy proto sync to 2024-07-06 ( </details> --- ### Configuration 📅 **Schedule**: Branch creation - Every minute ( * * * * * ) (UTC), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
