96ad6338 accidentally caused the javadoc and sources jars to no longer
be published for grpc-netty-shaded. It would appear to be due to the
jars being empty. This commit causes them to be published again.
- Use gradle configuration `api` for dependencies that are part of grpc public api signatures.
- Replace deprecated gradle configurations `compile`, `testCompile`, `runtime` and `testRuntime`.
- With minimal change in dependencies: If we need dep X and Y to compile our code, and if X transitively depends on Y, then our build would still pass even if we only include X as `compile`/`implementation` dependency for our project. Ideally we should include both X and Y explicitly as `implementation` dependency for our project, but in this PR we don't add the missing Y if it is previously missing.
maven_install is strongly superior to previous forms of grabbing dependencies
from Maven as it computes the appropriate versions to use from the full
transitive dependencies of all libraries used by an application. It also has
much less boilerplate and includes dependencies with generated targets.
In the future we will drop the jvm_maven_import_external usages and require
maven_install, at which point we can swap to using the `@maven' repository and
no longer depend on compat_repositories.
Fixes#5359
Examples and android projects were left unchanged. They can be changed
later.
No plugin versions were changed, to make this as non-functional of a
change as possible. Upgrading Gradle to 5.6 was necessary for
pluginManagement in settings.gradle.
Maven does not include transitive runtime dependencies in the
compile-time classpath (testing shows Gradle 4 does; docs say
Gradle 5 doesn't). So if a user references the shaded
NettyServerBuilder without also depending on grpc-core directly,
compilation will fail because AbstractServerImplBuilder couldn't
be found.
This isn't technically a problem, since we're not wanting to encourage
users to reference the shaded classes directly. But some users will
certainly reference the classes anyway and the error is pretty confusing
while also being trivially worked around. In other words: it justs
wastes people's time and benefits nobody.
Fixes#5881
Motivation:
To support TCP_USER_TIMEOUT(proposal). Nio doesn't support TCP_USER_TIMEOUT while Epoll and KQueue supports TCP_USER_TIME. Since most users/servers are using linux based system, adding Epoll is necessary. KQueue maybe supported later, but not in this PR.
To make it backward compatible for cases where channelType and eventLoop is mixed in with default and user provided object(s), we will fallback to Nio (NioSocketChannel, NioEventLoop). This ensures not breaking existing code (same as existing behavior). Users not specified both channelType and EventLoops will be affect by this Epoll change if netty-epoll is available.
In later version (possibly 1.22.0), the backward compatible behavior will be removed and it will start to throw exception since this is error prone.
There's no good way to provide users of ALTS a choice between grpc-netty
and grpc-netty-shaded. Since Netty is not exposed through the ALTS API
surface, we opt for the shaded version as it has fewer deployment
issues. However, this also means that we _can't_ expose any Netty API,
like EventLoopGroup.
This PR adds an automatic gradle format checker and reformats all the *.gradle files. After this, new changes to *.gradle files will fail to build if not in good format, just like checkStyle failure.
This fixes the gradle warning:
The SimpleWorkResult type has been deprecated and is scheduled to be
removed in Gradle 5.0. Please use WorkResults.didWork() instead.
