This takes some steps towards #525, but it won't be fixed until we
officially support OpenSSL. This is due to the fact that ALPN->NPN fallback
isn't supported with Jetty (since only one of the bootstrap plugins can be provided).
Reserve io.grpc for public API only, and all internal stuff in core to
io.grpc.internal, including the non-stable transport API.
Raise the netty/okhttp/inprocess subpackages one level up to io.grpc,
because they are public API and entry points for most users.
Details:
- Rename io.grpc.transport to io.grpc.internal;
- Move SharedResourceHolder and SerializingExecutor to io.grpc.internal
- Rename io.grpc.transport.{netty|okhttp|inprocess} to
io.grpc.{netty|okhttp|inprocess}
ChannelInactive should be called in all cases of channel going down, so
we only need to cancel ping there. Use goAwayStatus for the error, since
we will be putting the most effort into making that status useful.
When connectionError was set, goAwayStatus was also set, so we shouldn't
lose any errors.
NettyClientTransport doesn't really need a Throwable, it just needs a
Status. Passing a Status out of NettyClientHandler reduces the number of
places that need to do transport-specific translation of Throwables into
Status codes.
As described in SslHandler's documentation, handshakeFuture() and
SslHandshakeCompletionEvent are equivalent forms of learning of
handshake completion. Watching both causes double-logging and serves no
purpose.
Otherwise new writes will be written to the channel and will fail in
some unhelpful way.
Logging was removed as we really want to propagate the failure back to
the application via Calls, which is done by failing the
CreateStreamCommand message. Propagating back to the application via
call removes uncontrollable log spam and is necessary anyway to inform
the application what sort of failure occurred in order to appropriately
to react.
Note that even more importantly, this translates a RST_STREAM error code
to a gRPC status code. This is generally useful, but also necessary for
DEADLINE_EXCEEDED to be more reliable in 0eae0d9.
Fixes#687
Improved some consistency. writeHeaders was the only non-final
implementation method of ServerStream, even though it is really no
different than the others.
Resolves#511.
- In generated code, make CONFIG private and METHOD_* fields public.
METHOD_* fields are MethodDescriptors now, users of the CONFIG field
should switch to using the METHOD_* fields.
- Move MethodType into MethodDescriptor (#529).
- Unify the fully qualified method name. It is fully qualified service
name + slash + short method name. It doesn't have the leading slash.
- HandlerRegistry switches the key from short method name to fully
qualified method name.
- Pass CallOptions to Channel.newCall() and
ClientInterceptor.interceptCall().
- Remove timeout from AbstractStub.StubConfigBuilder and add deadline,
which is stored in a CallOptions inside the stub.
- Deadline is in nanoseconds in the clock defined by System.nanoTime().
It is converted to timeout before transmitting on the wire. Fail the
call with DEADLINE_EXCEEDED if it's already expired.
The mapping is poorly suited for gRPC. C and Go don't even do any
mapping. We can improve the mapping in the future, but it is very
important that users don't start depending on the current mapping.
This change is "inspired by" the original code, but is even more
conservative.
Fixes#477
GCM is very slow, and doesn't provide any benefit in unit tests. Even if
we were using tcnative and GCM is fast, using more available ciphers in
tests still makes sense. With this change building with Java 7 works
again, although that isn't the reason for the change.
On my machine with parallel building, it cuts full build time from
92 seconds to 39 seconds. For an incremental build after only changing
an interop test, the build time is cut from 73 seconds to 15 seconds.
When shutting down the Netty event loop, we have already guaranteed that
all users of it are no longer running. Doing a shutdownGracefully is
just delaying graceful JVM termination by two seconds. This is very
noticeable for short-lived processes, like our integration tests.
We would actually also prefer to shutdown quickly and get a
RejectedExecutionException for any newly queued tasks, because that
would be a legitimate bug.
shutdown() is deprecated, thus we do shutdownGracefully with a timeout
of 0.
isReady() can provide pushback while the call is in progress, but it
can also provide the pushback necessary when the client creates more
streams than permitted by MAX_CONCURRENT_STREAMS.
As part of this commit, OkHttp is now calling onReady() after call
creation (it previously never called onReady()).
