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.
JDK-8210522 changes the behaviour of Java reflection to filter out
security-sensitive fields in the java.lang.reflect.Field. This
prohibits Field.class.getDeclaredFields("modifiers") call we rely on
in this test. Until we have a good solution for setting a custom
storage for testing purposes, we'll have to skip this test
for JDK >= 11. Ref https://bugs.openjdk.org/browse/JDK-8210522
Add android:exported="true" tag to activities/services/receivers that specify an intent filter.
Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported` when the corresponding component has an intent filter defined. Future versions of the manifest merger, as well as the Android platform and the Playstore enforce this.
rls: Update implementation to match spec.
* Cleanup cache if exceeds max size when add an entry. Make cache entry size calculations more accurate
* Trigger pending RPC processing if unexpired backoff entries were removed from the cache by triggering helper to call it's parent updateBalancingState with the same state and picker
* Introduce minimum time before eviction (5 seconds)
* Change default accept ratio for AdaptiveThrottler from 1.2 -> 2.0
* Configuration validation
* When checking key names for duplicates also look at headers
* Check extra keys for duplicates

The log id is an incrementing value starting from 0. That means the same
binary on two different machines will have the same hashes for each
consecutive Channel. That was not at all the intension of CHANNEL_ID.
From gRFC A42:
> This can be used in similar situations to where Envoy uses
> connection_properties to hash on the source IP address.
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
rls: Avoid library returning the status codes which the status spec document says that the library will never return when talking to RLS server. Instead, always return UNAVAILABLE on errors.
* Provide context around error message from RLS server
No logic changes, just cleans up warnings to make spotting real problems easier.
Remove "public" declarations on interfaces
Remove duplicate semicolons (Java lines ending in ";;")
Remove unneeded import
Change non-javadoc comment to not start with "/**"
Remove unneeded explicit type declarations from generics
Fix broken javadoc links
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
This fixes builds including dependencies from Maven that use
io.grpc:grpc-services or io.grpc:grpc-xds. It resolves this error:
```
no such target '@io_grpc_grpc_java//services:services': target 'services' not declared in package 'services' defined by services/BUILD.bazel and referenced by '@maven//:io_grpc_grpc_services'
```
Fixes#9419
- Reduce nesting level by using `continue`
- Rearrange the order when it's possible to bail out early
- Add comments explaining what case it is, and the logic behind it
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.
rls: Change AdaptiveThrottler to use Ticker instead of TimeProvider
* Use a slot being null to mark invalid rather than relying on the slot's endNanos value.
Fixes#9048
* rls: Support multiple returned targets from RLS Server
Pick the first target that is not in TRANSIENT_FAILURE state. If none, use the first target.
Also initialize all targets returned from RLS so DataCache will contain a list of child policy wrappers.
Fixes#9236
