According to the docs, I can use bazel to build examples, but
retry-example is not supported in bazel config. So If you'll try to
build this example with bazel, you'll get an error:
```
examples git:(master) ✗ bazel build :retrying-hello-world-server :retrying-hello-world-client

```
The gradle wrapper was removed from example-oauth because we don't want
to maintain the wrapper copy in each example (at least right now it
doesn't make sense for it to be the only other example to have the
gradle wrapper).
Or rather, server response is ambiguous and this usage is not generally
what we mean when we say it. The example shows how to get an error for
any failed RPC, not just those coming from a failing server.

gcr.io/distroless/java:8 is no longer being updated. Java 8 isn't a
distroless option any more. Java 11 and 17 are options, but only Java 17
with Debian 12. The main alternative is to stick with Java 8 and use
something like docker.io/library/eclipse-temurin:8-jre . But there
doesn't seem to be much need to use an old JDK for these containers.
jib needed updating to support the oci manifest format used in the
updated image.
All the changes outside libs.versions.toml and examples were
because of ErrorProne. It didn't actually find anything to fix; signal
vs noise has gotten pretty bad with the newer checks.
Status was changed for ErrorProne's SuperCallToObjectMethod. With the
old code it didn't notice the trivial implementation. The fail-for-test
code wasn't used, so it was easiest to just remove it.
Some of the libs had their versions inlined; now that we have
:checkForUpdates it isn't much of a risk for versions to diverge when
there's only a few artifacts sharing a version. If we need 4+ artifacts
to have the same version, then it makes sense to still use a shared
version.
Dependencies not upgraded: google-auth-libray, mockito, netty, cronet
Per https://developer.android.com/about/versions/14#beta-3, Android U has reached the platform stability milestone which means that all external APIs are finalized.
We can thus bump the compileSdkVersion to 34 (U) and begin using APIs added there. We leave targetSdkVersion unchanged for now to avoid the broader evaluation of whether deeper changes may be necessary as part of the upgrade; this simply allows compile-time access to newer APIs without changing runtime behavior.
See b/274061424
Instead of a boolean, we now return a Status object. Status.OK
represents accepted addresses and other non-acceptance. This allows the
LB to provide more information about why a set of addresses were not
acceptable.
The status will later be sent to the name resolver as well to allow it
to also better react to to bad addresses.
Most changes are migrating from conventions to the equivalent
extensions. JMH, AppEngine, and Jib plugins trigger future compatibility
warnings with `--warning-mode all`.
The movement of configurations was to allow sourceSets to create the
configurations and then we just configure them. When configurations were
before sourceSets, we'd implicitly create the configuration.
The examples were _not_ updated to the newer Gradle, although the
non-Android examples work with the newer Gradle. The Android examples
use an older Android Gradle Plugin which will need to be upgraded first.

This updates the version of boringssl and removes the dependency on APR.
netty-tcnative 2.0.56.Final uses APR 1.7.0, so is in scope for
CVE-2021-35940, CVE-2022-28331, and CVE-2022-24963. netty-tcnative is
not actually vulnerable. The binary does not include apr_socket_sendv(),
apr_encode_*(), apr_pencode_*(), apr_decode_*(), apr_pdecode_*(). The
binary does include apr_time_exp_*() but it is unused code.
Unfortunately --gc-sections wasn't used during compilation.
apr_time_now() is used, but that just calls gettimeofday() and is not
vulnerable.
There's no panic here, but this updates netty-tcnative just a few weeks
before we would have ordinarily done so. Bumping the version makes life
easier for everyone.
The point of the sorting is to reduce the chances of merge conflicts. I
greatly prefer verboseness over cleverness in examples, but the tasks
can only be sorted manually and there's so many of them.
It is counter-productive to do this for the examples that have their own
project folder, as there's so few tasks in that case that they don't
need to be ordered.
The version used by protoc-gen-grpc-java will be upgraded separately,
because of large C++ build changes necessary. But that won't impact
users at all. We are upgrading to protoc 22.3; only the grpc plugin is
not upgraded.
Bazel is upgraded for both Java and C++.
Provides a server with both a greet service and the health service.
Client has an example of using the health service directly through the unary call
<a href="https://github.com/grpc/grpc-java/blob/master/services/src/main/proto/grpc/health/v1/health.proto">check</a>
to get the current health. It also utilizes the health of the server's greet service
indirectly through the round robin load balancer, which uses the streaming rpc
<strong>watch</strong> (you can see how it is done in
{@link io.grpc.protobuf.services.HealthCheckingLoadBalancerFactory}).
