We know the size won't be more than serializedHeaders.length, is
unlikely to be fewer, and very unlikely to be substantially fewer. This
prevents us from needing to resize the array in all cases.
Resolves#321
By default, ArrayDeque will be of size 16, which is an overkill for most
calls. "4" is not a magical number itself, but seems a better guess than
16 since we do have some knowledge of how much it will contain.
Resolves#320
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()).
Ideally OKHttp wouldn't do blocking I/O during start(), but it does and
fixing it is non-trivial. OkHttp can either throw an exception when it
encounters an error during start or it can shut itself down. Both
require changes in ChannelImpl, so we just choose to keep OkHttp's
current behavior and deal with it in ChannelImpl.
Operation is a term no longer used in gRPC. StatusException seems clear
and is concise. Moved out of Status class to remove stuttering.
The return types of as*Exception() is now explicitly the
Status.*Exception type.
If we notice something wrong with the headers, then we choose a nice
error message. But we are accidentally overwriting that message with
additional error details.
Set upper and lower bounds for Netty & OkHttp allocators based on transport limitations and benchmark results.
Fix OkHttp OutboundFlowController to chunk payloads larger than frameWriter.maxDataLength
Allow OkHttp to allocate buffers to FrameWriter larger than max DATA length
MessageFramer allows queing of data and explicit flushing. Sinks
generally can benefit from knowing when they are required to flush, so
we now tell them when MessageFramer received a flush so they only have
to flush when required.
ServerImpl.start() now throws IOException to make the error explicit.
This was previously being papered over by wrapping the exception in
RuntimeException.
call super.start(), and makes the subsequent use of other methods on the
call throw IllegalStateException.
Create ClientInterceptors.CheckedForwardingCall that handles exception
in start logic.
Create Forwarding[Server]Call[Listener] for generic decoration use
cases, with an abstract delegate() for flexibility.
Create SimpleForwarding[Server]Call[Listener] to replace now deprecated
forwarding classes.
1. Adds <property name="separateLineBetweenGroups" value="true"/> to CustomImportOrder to enfore blank line between imports groups.
2. Uses checkstyle 6.5, which fixed a bug of "CustomImportOrder checks import sorting according to ASCII order instead of case-insensitive alphabetical order".
Also add OkHttpReadableBuffer unit test, and increase the test string
length to expose the bug.
Also use array equality assertions in the base test, instead of
comparisons whose return value is discarded.
Fixes#231.
When the description is null, the exception message would be in the form
of "INTERNAL: null", which isn't very attractive, and makes it seem like
an error in itself. If the description is null, just use "INTERNAL".
The checkstyle.xml is a slightly modified version of the upstream Google
checkstyle configuration. All changes have comment describing them.
Lots of warnings were corrected. Examples is the only project that has
warnings still, as the necessary changes require some thought.
-Xlint:-options is not available on some earlier JDK 7s, but won't fail
if unsupported. It prevents the warning wanting bootclasspath specified
since target/source is 1.6.
This allows sooner delivery of errors. We never needed to stop delivery
for unexpected EOS, but instead the application would have been required
to request() another message before delivering. Stalling MessageDeframer
sooner removes the need for the application to request another message
before noticing that the buffers are empty.
The Http2ClientStream should not close the buffer in this case since
it's already been given to the deframer and potentially to the user.
Added cleanup code to MessageDeframer and AbstractClientStream to make
sure that we free the Buffer when appropriate.
Some early grpc users on Android are using a very old Guava. They are
working on upgrading, but it will take time. This alone is not enough
for "old guava" compilibility; expect more to come.
OkHttp no longer cancels all calls on shutdown, as we want to allow
graceful shutdown. Such cancelling behavior will likely be provided by
Channel in the future.
OkHttp should now have a thread-safe implementation of newStream.
Previously 'lock' was not held when checking goAway and the checking in
AbstractClientTransport was redundant.
Netty was thread-safe, but it was very hard to tell what guarantees were
necessary and what guarantees each piece was providing.
Previously streams were being partially orphaned if there was an
interruption during stream creation. To handle cancellation,
AbstractClientStream's cancel() had to be changed remove the
"optimization" otherwise, again, the stream would be orphaned.
This change loses asynchronous notification of channel state-change and
a way to wait until the channel is actually connected. Both of these are
expected to be added back as part of a health API. The important
distinction from Service is that ChannelImpl never permanently fails and
can revert from being started to connecting again.

Summary of changes:
1) Merged the interfaces MessageDeframer2.Sink and DeframerListener into
MessageDeframer2.Listener. This simplifies the interface of
MessageDeframer2 quite a bit.
2) Added a deliveryPaused() handler to MessageDeframer2.Listener, which
is called by the deframer when there is not enough data to read/deliver
the next message.
3) Modified AbstractStream and AbstractClientStream to manage the timing
of when the closed() event is delivered to the listener. The
transportReportStatus ultimately controls this by creating a task to
close the listener. It either runs this task immediately or when the
next deliveryPaused() event occurs.

The client now checks certificates and performs hostname verification.
Tests check certificates, so the server uses a cert that the client
trusts.
Only the client portion of SslContextFactory was previously used.
Applications that want to ignore certificates (i.e., for testing) can
use io.netty.handler.ssl.util.InsecureTrustManagerFactory instead.
The MOE configuration was already failing to work, and so required the
simple mapping for examples in addition to what was needed for the new
certs.

Headers and trailers are only received on client-side, so we need a
client-specific listener. Close() also has slightly different semantics
between server-side and client-side.
Most of the changes are simple name changes, but AbstractServerStream does update to the new close() semantics.
-------------
Created by MOE: http://code.google.com/p/moe-java

We purposefully avoid going through the (de)framer, since close()
behavior is specific to whether on client or server.
AbstractClientStream and AbstractServerStream handle mapping the events
to appropriate semantics, but require stashing status/trailer for later
use.
It was very interesting getting to a point where we could support the old
and new protocol; that is probably the most detailed-oriented portion of
the CL. There are some interface hacks going on, but those will
naturally be removed when we trash the gRPC v1 framer.
