Guava 20 introduced some overloading optimizations for Preconditions
that require using Guava 20+ at runtime. Unfortunately, Guava 20 removes
some things that is causing incompatibilities with other libraries, like
Cassandra. While the incompatibility did trigger some of those libraries
to improve compatibility for newer Guavas, we'd like to give the
community more time to work through it. See #2688
At this commit, we appear to be compatible with Guava 18+. It's not
clear if we want to actually "support" 18, but it did compile. Guava 17
doesn't have at least MoreObjects, directExecutor, and firstNotNull.
Guava 21 compiles without warnings, so it should be compatible with
Guava 22 when it is released.
One test method will fail with the upcoming Guava 22, but this won't
impact applications. I made MoreThrowables to avoid using any
known-deprecated Guava methods in our JARs, to reduce pain for those
stuck with old versions of gRPC in the future (July 2018).
In the stand-alone Android apps I removed unnecessary explicit deps
instead of syncing the version used.
I'm quite confused how we went this long using Jetty ALPN for the Netty
tests. Anyway, we strongly prefer tcnative, so we should be using it in
the tests.
ErrorProne provides static analysis for common issues, including
misused variables GuardedBy locks.
This increases build time by 60% for parallel builds and 30% for
non-parallel, so I've provided a way to disable the check. It is on by
default though and will be run in our CI environments.
Fixes NPE when keepalive is enabled.
* Move creation of keepAliveManager to the bottom of start()
* Enable keepAlive in NettyClientTransportTest
* Add test cases checking if keepalive is enabled/disabled, specifically.
Fixes#2726
Futures almost universally should be handled in some way when being
returned, either to receive the value or to cancel scheduled tasks to
prevent leaks.
Netty is a bit of a special case though, since it constantly returns
futures that you ignore (even adding a listener returns the "this"
future). So we want to suppress the warning for code using Netty instead
of trying to fix it. When we enable ErrorProne in the build, we should
start passing -Xep:FutureReturnValueIgnored:OFF in the compilerArgs.
The new plugin uses a newer version of animalsniffer, allows overriding
the animalsniffer version used, and has up-to-date handling. The
up-to-date handling cuts fully incremental parallel build times in half,
from 5.5s to 2.7s.
The previous plugin was supposed to be verifying tests. However, either
it wasn't verifying them or its verification was broken.
The LBv2 setter was added in #2658 as an abstract method, which breaks
anyone who implements ManagedChannelBuilder. Here we add a default
implementation that throws.
Commit 65e4d9f4 broke the jwt_token_creds. It is believed to be because
the JWT does not see the authority passed to overrideAuthority. So the
changes to interop-testing client are temporarily reverted here. Note
that this breaks GRPC_PROXY_EXP testing, so the incompatibility needs to
be resolved.
Solving #2682 will allow reverting this change.

This is needed because in interceptor tests, often the types cannot
be changed. The void methods stay for users who are writing tests
where they actually don't care about types. The noop methods
require types to be specified. This is for users who don't care
about the implementation. These represent different levels of
commitment.
This eases the transition of code Mocking MethodDescriptor, which
breaks in this release.
In some environments DNS is not available and is performed by the
CONNECT proxy. Nothing "special" should need to be done for these
environments, but the previous support took shortcuts which knowingly
would not support such environments.
This change should fix both OkHttp and Netty. Netty's
Bootstrap.connect() resolved the name immediately whereas using
ChannelPipeline.connect() waits until the address reaches the end of the
pipeline. Netty uses NetUtil.toSocketAddressString() to get the name of
the address, which uses InetSocketAddress.getHostString() when
available.
OkHttp is still using InetSocketAddress.getHostName() which may issue
reverse DNS lookups. However, if the reverse DNS lookup fails, it should
convert the IP to a textual string like getHostString(). So as long as
the reverse DNS maps to the same machine as the IP, there should only be
performance concerns, not correctness issues. Since the DnsNameResolver
is creating unresolved addresses, the reverse DNS lookups shouldn't
occur in the common case.
