"EXP" stood for experimental and all documentation that referenced it made it clear it was experimental. It's been some years since we started logging a message when it was used to say it will be deleted. There's no time like the present to delete it.
panic() calls a good amount of code, so it could get another exception.
The SynchronizationContext is running on an arbitrary thread and we
don't want to propagate this secondary exception up its stack (to be
handled by its UncaughtExceptionHandler); it we wanted that we'd
propagate the original exception.
This second exception will only be seen in the logs; the first exception
was logged and will be used to fail RPCs.

ffcc360ba adjusted updateBalancingState() to require being run within
the sync context. However, it still queued the work into the sync
context, which was unnecessary. This re-entering the sync context
unnecessarily delays the new state from being used.
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.
