Currently this improves 2 flows
1. Known length message which length is greater than 1Mb. Previously the
first buffer was 1Mb, and then many buffers of 4096 bytes (from
CodedOutputStream), now subsequent buffers are also up to 1Mb
2. In case of compression, the first write is always 10 bytes buffer
(gzip header), but worth allocating more space
* core: updates the backoff range being used from [0, 1] to [0.8, 1.2] as per the A6 redefinition
* adds a flag for experimental jitter
* xds: Allow FaultFilter's interceptor to be reused
This is the only usage of PickSubchannelArgs when creating a filter's
ClientInterceptor, and a follow-up commit will remove the argument and
actually reuse the interceptors. Other filter's interceptors can
already be reused.
There doesn't seem to be any significant loss of legibility by making
FaultFilter a more ordinary interceptor, but the change does cause the
ForwardingClientCall to be present when faultDelay is configured,
independent of whether the fault delay ends up being triggered.
Reusing interceptors will move more state management out of the RPC path
which will be more relevant with RLQS.

Setting the authority is only useful when creating a real stream, as
there will be a following pick otherwise. In addition, DelayedStream
will buffer each call to setAuthority() in a list and we don't want that
memory usage. Note that no LBs are using this feature yet, so users
would not have been exposed to the memory use.
We also needed to setAuthority() when the LB selected a subchannel on
the first pick attempt.
* Have acceptResolvedAddresses() do a seek when in CONNECTING state and cleanup removed subchannels when a seek was successful.
Move cleanup of removed subchannels into a method so it can be called from 2 places in acceptResolvedAddresses.
Since the seek could mean we never looked at the first address, if we go off the end of the index and haven't looked at the all of the addresses then instead of scheduleBackoff() we reset the index and request a connection.
* Move creating the retry timer in handleRpcStreamClosed to as late as possible and call `close` so that the `call` is cancelled.
Also add some debug logging.
In e08b9db20 we added `@DoNotCall` annotations to some call sites, but
Bazel used an older version of ErrorProne that complained at times it
shouldn't. The minimum version of Bazel we test/support is now Bazel 6,
well past Bazel 3.4+.
grpc-binder's upcoming AndroidIntentNameResolver needs to know the target Android user so it can resolve target URIs in the correct place. Unfortunately, Android's built in intent:// URI scheme has no way to specify a user and in fact the android.os.UserHandle object can't reasonably be encoded as a String at all.
We solve this problem by extending NameResolver.Args with the same type-safe and domain-specific Key<T> pattern used by CallOptions, Context and CreateSubchannelArgs. New "custom" arguments could apply to all NameResolvers of a certain URI scheme, to all NameResolvers producing a particular type of java.net.SocketAddress, or even to a specific NameResolver subclass.
In 61f19d707a I swapped the signatures to use the version catalog. But I
failed to preserve the `@signature` extension and it all seemed to
work... But in fact all the animalsniffer tasks were completing as
SKIPPED as they lacked signatures. The build.gradle changes in this
commit are to fix that while still using version catalog.
But while it was broken violations crept in. Most violations weren't
too important and we're not surprised went unnoticed. For example, Netty
with TLS has long required the Java 8 API
`setEndpointIdentificationAlgorithm()`, so using `Optional` in the same
code path didn't harm anything in particular. I still swapped it to
Guava's `Optional` to avoid overuse of `@IgnoreJRERequirement`.
One important violation has not been fixed and instead I've disabled the
android signature in api/build.gradle for the moment. The violation is
in StatusException using the `fillInStackTrace` overload of Exception.
This problem [had been noticed][PR11066], but we couldn't figure out
what was going on. AnimalSniffer is now noticing this and agreeing with
the internal linter. There is still a question of why our interop tests
failed to notice this, but given they are no longer running on pre-API
level 24, that may forever be a mystery.
[PR11066]: https://github.com/grpc/grpc-java/pull/11066
ObjectPool is our standard solution for dealing with the
sometimes-shutdown resources. This was implemented by a contributor not
familiar with regular tools.
There are wider changes that can be made here, but I chose to just do a
smaller change because this class is used by GrpclbNameResolver.
When java.time.Instant is available use the timestamp from this class in nano precision rather than using System.currentTimeInMillis and converting it to nanos.
Fixes#5494.
If a panic is followed a panic, we'd ignore the second. But if an
exception happens while entering panic mode we may fail to update the
picker with the first error. This is "fine" from a correctness
standpoint; all bets are off when panicking and we've already logged the
first error. But failing RPCs can often be more easily seen than just
the log.
Noticed because of http://yaqs/8493785598685872128
Combined success / error status passed via ResolutionResult to the NameResolver.Listener2 interface's onResult2 method - Addresses in the success case or address resolution error in the failure case now get set in ResolutionResult::addressesOrError by the internal name resolvers.
* Change PickFirstLeafLoadBalancer to only have 1 subchannel at a time if environment variable GRPC_SERIALIZE_RETRIES == true.
Cache serializingRetries value so that it doesn't have to look up the flag every time.
Clear the correct task when READY in processSubchannelState and move the logic to cancelScheduledTasks
Cleanup based on PR review
remove unneeded checks for shutdown.
* Fix previously broken tests
* Shutdown previous subchannel when run off end of index.
* Provide option to disable subchannel retries to let PFLeafLB take control of retries.
* InternalSubchannel internally goes to IDLE when sees TF when reconnect is disabled.
Remove an extra index.increment in LeafLB
* use an attribute from resolved addresses IS_PETIOLE_POLICY to control whether or not health checking is supported so that top level versions can't do any health checking, while those under petiole policies can.
Fixes#11413
Detachable lets a buffer outlive its original lifetime. The new lifetime
is application-controlled. If the application fails to read/close the
stream, then the leak detector wouldn't make clear what code was
responsible for the buffer's lifetime. With this touch, we'll be able to
see detach() was called and thus know the application needs debugging.
Realized when looking at b/364531464, although I think the issue is
unrelated.
It doesn't do anything.
Call scheduleNextConnection() unconditionally since it is responsible
for checking if `enableHappyEyeballs == true`. It's also surprising to
check in the CONNECTING case but not the IDLE case.
It is trivial to avoid the exception from
addressIndex.getCurrentAddress(). The log message was inaccurate, as the
subchannel might have been TRANSIENT_FAILURE. The only important part of
the condition was whether the subchannel was the current subchannel.
It will never throw, because it would only throw if helper is null, but
helper is checkNotNull()ed in the constructor. It could have checked for
a null return value instead; since it hasn't been, it is clear we don't
need this check.
Bazel had the dependency added because of #5046, where Guava was
depending on it as compile-only and Bazel build have "unknown enum
constant" warnings. Guava now has a compile dependency on j2objc, so
this workaround is no longer needed. There are currently no version skew
issues in Gradle, which was the only usage.
