There was no point to using subchannels as keys to
subchannelToReportListenerMap, as the listener is per-child. That meant
the keys would be guaranteed to be known ahead-of-time and the
unsynchronized getOrCreateOrcaListener() during picking was unnecessary.
The picker still stores ChildLbStates to make sure that updating weights
uses the correct children, but the picker itself no longer references
ChildLbStates except in the constructor. That means weight calculation
is moved into the LB policy, as child.getWeight() is unsynchronized, and
the picker no longer needs a reference to helper.
A package-private class isn't visible and `@Internal` is stronger than
experimental. The only way users should use WRR is via the
weight_round_robin string, and that's already not suffixed with
_experimental.

Some addresses are equal even though their toString is different
(InetSocketAddress ignores the hostname when it has an address). And
some addresses are not equal even though their toString might be the
same (AnonymousInProcessSocketAddress doesn't override toString()).
InetSocketAddress/InetAddress do not cache the toString() result. Thus,
even in the worst case that uses a HashSet, this should use less memory
than the earlier approach, as no strings are formatted. It probably also
significantly improves performance in the reasonably common case when an
Endpoint is created just for looking up a key, because the string
creation in the constructor isn't then amorized.
updateChildrenWithResolvedAddresses(), for example, creates n^2 Endpoint
objects for lookups.
It came up in #11073, and I saw it could use a little updating. Notably,
I'm linking to a guide to what Git commit messages should look like. I
also tried to make the language less heavy-handed and demanding.
This reverts commit 9ba2f9dec5.
It causes a channel panic due to unimplemented onResult2().

They share very little code, and we really don't want RoundRobinLb to be
public and non-final. Originally, WRR was expected to share much more
code with RR, and even delegated to RR at times. The delegation was
removed in 111ff60e. After dca89b25, most of the sharing has been moved
out into general-purpose tools that can be used by any LB policy.
FixedResultPicker now has equals to makes it as a EmptyPicker
replacement. RoundRobinLb still uses EmptyPicker because fixing its
tests is a larger change. OutlierDetectionLbTest was changed because
FixedResultPicker is used by PickFirstLeafLb, and now RoundRobinLb can
squelch some of its updates for ready pickers.
`cncf/xds`: Sync protos to the latest imported version
cncf/xds@024c85f (commit 2024-07-23, cl/655545156).
Should be a noop, just a routine xDS proto update to make upcoming
RLQS-related imports simpler, see related #11401.
Note that CEL is only added as a bazel dependency as now it's required
to build cncf/xds. Actual third-party source import will be done in
the follow up PR, where RLQS dependencies are added to the import
scripts.
Otherwise, the server will continue sending updates and if we
re-subscribe to the last resource, the server won't re-send it. Also
completely remove the per-type state, as it could only add confusion.
`envoyproxy/envoy`: Sync protos to the latest imported version
ab911ac2ff
(commit 2024-07-06, cl/651956889).
Should be a noop, just a routine xDS proto update to make upcoming
RLQS-related imports simpler.
Introducing NameResolver listener method "Status Listener2::onResult2(ResolutionResult)" that returns Status of the acceptance of the name resolution by the load balancer, and the Name Resolver will call this method for both success and error cases.
From gRFC A58:
> When less than two subchannels have load info, all subchannels will
> get the same weight and the policy will behave the same as round_robin
We don't include protobuf in IO_GRPC_GRPC_JAVA_ARTIFACTS, so there might
not actually be an alias available for it to @com_google_protobuf. While
we could add it, it is easier to use the @com_google_protobuf references
directly.
This was preventing `bazel query 'deps(//...)' from succeeding, because
it couldn't find javalite.
Since Bazel 6 [1], Bazel has used com_google_protobuf for javalite. We
only used the other repo because Bazel expected it, which was because
Protobuf split out javalite to a separate branch for a while. Since
everything is now reunified, we can use a singular protobuf repo.

V1 version of the proto reflection service, as the v1.alpha service has been deprecated.
* Create V1 alpha service wrapping underlying V1 service, by modifying the ServerServiceDefinition.
* Create ProtoReflectionService for the v1alpha proto by producing a ServerServiceDefinition constructed from that of the v1 service but with the service and method names and proto descriptors modified.
Issue #6724.
Java 8 isn't installed, and was needed by the old Android SDK. With the
current SDK, it can work on Java 11 but it needs some dependencies
installed.
Python 2.7 isn't available any more, but instead of porting to Python 3,
it was just replaced with a curl command.
The GSON upgrade slightly changed an error string, so the test was
updated to be less of a change detector.
Some OpenTelemetry dependencies are alpha versions, so needed an
adjustment in build.gradle to accept the versions. Similarly, Undertow
includes Final in its version numbers which needs to be accepted.
