This introduces an AbstractStream2 that is intended to replace the
current AbstractStream. Only server-side is implemented in this commit
which is why AbstractStream remains. This is mostly a reorganization of
AbstractStream and children, but minor internal behavioral changes were
required which makes it appear more like a reimplementation.
A strong focus was on splitting state that is maintained on the
application's thread (with Stream) and state that is maintained by the
transport (and used for StreamListener). By splitting the state it makes
it much easier to verify thread-safety and to reason about interactions.
I consider this a stepping stone for making even more changes to
simplify the Stream implementations and do not think some of the changes
are yet at their logical conclusion. Some of the changes may also
immediately be replaced with something better. The focus was to improve
readability and comprehesibility to more easily make more interesting
changes.
The only thing really removed is some state checking during sending
which is already occurring in ServerCallImpl.
This change updates the behavior of the core compression semantics. Previously,
if the codec was "identity", nothing was set on the wire. This is allowed by
the spec, but doesn't match what wrapped languages do.
Additionally, the interop tests will now attempt to honor the requested
compression.
OkHttpClientTransport has a fix for shutdown during start which
prevented transportTerminated from being called. It also no longer fails
pending streams during shutdown. Lifecycle management in general was
revamped to be hopefully simpler and more precise. In the process GOAWAY
handling (both sending and receiving) was improved.
With some of the changes, the log spam generated was immense and
unhelpful (since many exceptions are part of normal operation on
shutdown). This change reduces the amount of log spam to nothing.
This improves our documentation for the gradle protobuf plugin, as its
version is dependent on the gradle version.
Gradle now has the --tests flag, performance improvements, and support
for OpenPGP subkeys.
Without the warm up I saw large deltas, like 2,262,968ns and
1,712,558ns, on my machine. With the single-line warm up the deltas
decreased dramitically, like 385ns and 536ns. Since our times are so
much better now, decreasing the required delta to 10ms seems reasonable.
This would seem to support the theory that the flakiness was caused by
the class loader, which may even be doing I/O.

Commit 9597382 introduced InternalHandlerRegistry as the main registry,
which uses a flat map from fullMethodNames to handlers, thus addressed
the original intention of this comment.
See #933
- Create InternalHandlerRegistry, an immutable look-up table. Handlers
passed to ServerBuilder.addService() go to this registry. This covers
the most common use cases. By keeping the registry internal we could
freely change the registry's interface to accommodate optimizations,
e.g., for hpack.
- The internal registry uses a flat fullMethodName -> handler look-up
table instead of a hierarchical one used before. It faster because it
saves one look-up and a substring.
- Introduces the fallback registry, settable by
ServerBuilder.fallbackHandlerRegistry(), for advanced users who want a
dynamic registry. Moved the current MutableHandlerRegistryImpl to
io.grpc.util.MutableHandlerRegistry as a stock implementation of the
fallback registry. The io.grpc.MutableHandlerRegistry interface is now
removed.
It is trivial to call withCancellation() after the fork().
CancellableContexts are required to be cancelled eventually, so
returning Context instead is easier when cancellation is not necessary.
Fixes#1626
They are mostly noise at the moment. The 'changes' status could be
useful, but is a bit too noisy given flakiness in our coverage.
Threshold of 1% suppresses the noise for project-wide coverage.
grpc-all contains a copy of all the classes and sources of "important"
artifacts. The copy causes problems when grpc-all is mixed with the
individual artifacts like grpc-netty or grpc-core, since they will
collide on the classpath. Avoiding the copy fixes the problem.

This reverts commit 8825f355df.
The commit changed the package name of services that were used across
languages. That broke their functionality pretty severely. The changes
require more coordination with others.
