Motivation:
We often receive a bug report or a pull request which do not give us
enough information. If CONTRIBUTING.md exists in the repository, Github
will display some notice in the beginning of the issue submission form,
which might increase the overall quality of the bug reports and pull
requests.
Modification:
Write CONTRIBUTING.md
Result:
Potentially higher-quality bug reports and pull requests
This changeset removes the separate message headers and merges the
field directly into the messages. This greatly simplifies the
object hierachy and also saves header allocations in the pipeline.
Merged WebSocketClient and WebSocketSslClient
Add private constructors to fix checkstyle errors.
More checkstyle madness.
made WebSocketClientRunner final
Previously ConcurrentHashMapV8 evaulated ((x | 1) == 0), an expression
that always returned false. This commit brings Netty closer to the
Java 8 implementation.
Motivation:
When an HttpResponseDecoder decodes an invalid chunk, a LastHttpContent instance is produced and the decoder enters the 'BAD_MESSAGE' state, which is not supposed to produce a message any further. However, because HttpObjectDecoder.invalidChunk() did not clear this.message out to null, decodeLast() will produce another LastHttpContent message on a certain situation.
Modification:
Do not forget to null out HttpObjectDecoder.message in invalidChunk(), and add a test case for it.
Result:
No more consecutive LastHttpContent messages produced by HttpObjectDecoder.
This changeset is related to #2182, which exposes the failure in
the http codec, but the memcache codec works very similar. In addition,
better failure handling in the decoder has been added.
This also does factor out some logic of ChannelOutboundBuffer. Mainly we not need nioBuffers() for many
transports and also not need to copy from heap to direct buffer. So this functionality was moved to
NioSocketChannelOutboundBuffer. Also introduce a EpollChannelOutboundBuffer which makes use of
memory addresses for all the writes to reduce GC pressure
Motivation:
ChunkedWriteHandler can sometimes fail to write the last chunk of a ChunkedInput due to an I/O error. Subsequently, the ChunkedInput's associated promise is marked as failure and the connection is closed. When the connection is closed, ChunkedWriteHandler attempts to clean up its message queue and to mark their promises as success or failure. However, because the promise of the ChunkedInput, which was consumed completely yet failed to be written, is already marked as failure, the attempt to mark it as success fails, leading a WARN level log.
Modification:
Use trySuccess() instead of setSuccess() so that the attempt to mark a ChunkedInput as success does not raise an exception even if the promise is already done.
Result:
Fixes#2249
Motivation:
Currently, it is impossible to give a user the full control over what to do in response to the request with 'Expect: 100-continue' header. Currently, a user have to do one of the following:
- Accept the request and respond with 100 Continue, or
- Send the reject response and close the connection.
.. which means it is impossible to send the reject response and keep the connection alive so that the client sends additional requests.
Modification:
Added a public method called 'reset()' to HttpObjectDecoder so that a user can reset the state of the decoder easily. Once called, the decoder will assume the next input will be the beginning of a new request.
HttpObjectAggregator now calls `reset()`right after calling 'handleOversizedMessage()' so that the decoder can continue to decode the subsequent request even after the request with 'Expect: 100-continue' header is rejected.
Added relevant unit tests / Minor clean-up
Result:
This commit completes the fix of #2211
Exposing the constant as a public static final field is usually not a
good idea because it gives less flexibility to us when we happen to
change our internal implementation.
