Implements a fake load balancer with round robin like behavior in order
to test an outlier detection scenario where a subchannel goes from
having multiple associated addresses to one.
Stop further ejection if the ejection percentage is lesser than or equal
to the maximum ejection percentage. Previously this was only done when
the current ejection percentage was lesser than the maximum.
Instead of strictly enforcing the max ejection percentage setting,
allow one additional ejection past the maximum. This quarantees at least
one ejection and matches Envoy proxy behavior.
New outlier detection load balancer.
Tracks all RPC results to the addresses it is configured with and periodically attempts
to detect outlier. It wraps a child load balancer from which it hides any addresses that
are deemed outliers.
As specified in gRFC A50: gRPC xDS Outlier Detection Support:
https://github.com/grpc/proposal/blob/master/A50-xds-outlier-detection.md

It's been 17 months since the check was introduced, which is plenty for
the migration. Leaving ignoreRefreshNameResolutionCheck() in-place to
let users delete their call sites. We'll remove the method after a few
releases.
Fixes#9409
Introduces a new acceptResolvedAddresses() to the LoadBalancer.
This will now be the preferred way to handle addresses from the NameResolver. The existing handleResolvedAddresses() will eventually be deprecated.
The new method returns a boolean based on the LoadBalancers ability to use the provided addresses. If it does not accept them, false is returned. LoadBalancer implementations using the new method should no longer implement the canHandleEmptyAddressListFromNameResolution(), which will eventually be removed, along with handleResolvedAddresses().
Backward compatibility will be maintained so existing load balancers using handleResolvedAddresses() will continue to work.
Additionally the previously deprecated handleResolvedAddressGroups() method is removed.
%s is fairly safe (requires a Formattable to use Locale), so %d is the
main risk item. Places that really didn't need to use String.format()
were converted to plain string concatenation. Logging locations were
generally converted to using the log infrastructure's delayed
formatting, which is generally locale-sensitive but we're okay with
that. That wasn't done in okhttp, however, because Android frequently
doesn't use MessageFormat so we'd lose the parameters. Everywhere else
was explicitly defined to be Locale.US, to be consistent independent of
the default system locale.
Fix a bug where the server stream delivers halfClose() to the call during cancellation. It happens when call has a short deadline. Server sees `INTERNAL, desc: Half-closed without a request` due to the bug.
This can avoid creating an additional 736 tasks (previously 502 out of
1591 were not created). That's not all that important as the build time
is essentially the same, but this lets us see the poor behavior of the
protobuf plugin in our own project and increase our understanding of how
to avoid task creation when developing the plugin. Of the tasks still
being created, protobuf is the highest contributor with 165 tasks,
followed by maven-publish with 76 and appengine with 53. The remaining
59 are from our own build, but indirectly caused by maven-publish.
If the failure is before the NameResolver has returned the first time,
RPCs would be queued waiting for service config. We don't want to use
the ConfigSelector, as we are trying to circumvent the NameResolver and
LoadBalancer.
Fixes#9257
This moves our depedencies into a plain file that can be read and
updated by tooling. While the current tooling is not particularly better
than just using gradle-versions-plugin, it should put us on better
footing. gradle-versions-plugin is actually pretty nice, but will be
incompatible with Gradle 8, so we need to wait a bit to see what the
future holds.
Left libraries as an alias for libs to reduce the commit size and make
it easier to revert if we don't end up liking this approach.
We're using Gradle 7.3.3 where it was an incubating fetaure. But in
Gradle 7.4 is became stable.
These APIs were added to NettyServerBuilder for gRFC A8 and A9. They are
important enough that they shouldn't require using the perma-unstable
transport API to access. This change also allows using these methods
with grpc-netty-shaded.
Fixes#8991
* api: add support for SocketAddress types in ManagedChannelProvider
also add support for SocketAddress types in NameResolverProvider
Use scheme in target URI to select a NameRseolverProvider and get
that provider's supported SocketAddress types.
implement selection in ManagedChannelRegistry of appropriate
ManagedChannelProvider based on NameResolver's SocketAddress types
There was an attempt to use different epochs for the wall clock and the
monotonic clock. However, 123456789 is actually less than a second.
We want the gap between clocks to be at least a day. This issue was
discovered in #8968.
This separation found a bug in an RLS test where it was mixing epochs.
However, it was only a problem in the test. The code under test is
wrongly using wall clock for calculation durations, but that seems to be
a wide-spread problem and will need to be handled separately.
`setCall()` returns drainPendingCalls runnable only when there are calls to drain, otherwise return null. Preserved the behaviour of `start()` and `cancel()`, as they are protected by `delayOrExecute()`.
Update javadoc to mention this previously-unwritten rule.
Update earlyServerClose_serverFailure_withClientCancelOnListenerClosed to obey it.
Update BinderTransport to fail sooner if this rule is broken.
The test for 10,000 took 10s to run and would time out when using other
tools like TSAN. "10000" was just a "very large number less than
infinity" and 1000 serves the same purpose and should similarly never
trigger. Using 1000 has the test run in 1s and TSAN completes in 17s.
The limit was originally added in dc6eaccc.
Limit the total number of local-only transparent retries per RPC for the moment to mitigate any potential bug that would trigger infinite loop of transparent retries. If the limit is exceeded, fail the RPC.
In core, add a new enum element to `RpcProgress` for the case that the stream is closed even before anything leaves the client. `RetriableStream` will do unlimited transparent retry for this type of `RpcProgress` since they are local-only.
In netty, call `tranportReportStatus()` for pending streams on failure.
