Motivation:
Make it more clear what the output of HttpObjectAggregator is and that it need to come after the encoder in the pipeline.
Modifications:
Change javadocs to make things more clear.
Result:
Better docs
Motivation:
Fix leaks reported during running SpdyFrameDecoderTest
Modifications:
Make sure the produced buffers of SpdyFrameDecoder and SpdyFrameDecoderTest are released
Result:
No more leak reports during run the tests.
Motivation:
Fix leaks reported during running SpdyFrameDecoderTest
Modifications:
Make sure the produced buffer of SpdyFrameDecoder is released
Result:
No more leak reports during run the tests.
Motivation:
Fix leaks reported during SPDY test.
Modifications:
Use ReferenceCountUtil.releaseLater(...) to make sure everything is released once the tests are done.
Result:
No more leak reports during run the tests.
Motivation:
Currently, the SPDY frame encoding and decoding code is based upon
the ChannelHandler abstraction. This requires maintaining multiple
versions for 3.x and 4.x (and possibly 5.x moving forward).
Modifications:
The SPDY frame encoding and decoding code is separated from the
ChannelHandler and SpdyFrame abstractions. Also test coverage is
improved.
Result:
SpdyFrameCodec now implements the ChannelHandler abstraction and is
responsible for creating and handling SpdyFrame objects.

Motivation:
Currently the CORS support only handles a single origin, or a wildcard
origin. This task should enhance Netty's CORS support to allow multiple
origins to be specified. Just being allowed to specify one origin is
particulary limiting when a site support both http and https for
example.
Modifications:
- Updated CorsConfig and its Builder to accept multiple origins.
Result:
Users are now able to configure multiple origins for CORS.

Motivation:
Previously, we used URLDecoder.decode(...) to decode url-encoded data. This generates a lot of garbage and takes a considerable amount of time.
Modifications:
Replace URLDecoder.decode(...) with QueryStringDecoder.decodeComponent(...)
Result:
Less garbage to GC and faster decode processing.
Motivation:
When running the build with Java 8 the following error occurred:
java: reference to preflightResponseHeader is ambiguous
both method
<T>preflightResponseHeader(java.lang.CharSequence,java.lang.Iterable<T>)
in io.netty.handler.codec.http.cors.CorsConfig.Builder and method
<T>preflightResponseHeader(java.lang.String,java.util.concurrent.Callable<T>)
in io.netty.handler.codec.http.cors.CorsConfig.Builder match
The offending class was CorsConfigTest and its shouldThrowIfValueIsNull
which contained the following line:
withOrigin("*").preflightResponseHeader("HeaderName", null).build();
Modifications:
Updated the offending method with to supply a type, and object array, to
avoid the error.
Result:
After this I was able to build with Java 7 and Java 8
Motivation:
An intermediary like a load balancer might require that a Cross Origin
Resource Sharing (CORS) preflight request have certain headers set.
As a concrete example the Elastic Load Balancer (ELB) requires the
'Date' and 'Content-Length' header to be set or it will fail with a 502
error code.
This works is an enhancement of https://github.com/netty/netty/pull/2290
Modifications:
CorsConfig has been extended to make additional HTTP response headers
configurable for preflight responses. Since some headers, like the
'Date' header need to be generated each time, m0wfo suggested using a
Callable.
Result:
By default, the 'Date' and 'Content-Lenght' headers will be sent in a
preflight response. This can be overriden and users can specify
any headers that might be required by different intermediaries.
Motivation:
If the last item analyzed in a previous received HttpChunk/HttpContent was a part of an attribute's name, the read index was not set to the new right place and therefore raizing an exception in some case (since the "new" name analyzed is empty, which is not allowed so the exception).
What appears there is that the read index should be reset to the last valid position encountered whatever the case. Currently it was set when only when there is an attribute not already finished (name is ok, but content is possibly not).
Therefore the issue is that elements could be rescanned multiple times (including completed elements) and moreover some bad decoding can occur such as when in a middle of an attribute's name.
Modifications:
To fix this issue, since "firstpos" contains the last "valid" read index of the decoding (when finding a '&', '=', 'CR/LF'), we should add the setting of the read index for the following cases:
'lastchunk' encountered, therefore finishing the current buffer
any other cases than current attribute is not finished (name not found yet in particular)
So adding for this 2 cases:
undecodedChunk.readerIndex(firstpos);
Result:
Now the decoding is done once, content is added from chunk/content to chunk/content, name is decoded correctly even if in the middle of 2 chunks/contents.
A Junit test code was added: testChunkCorrect that should not raized any exception.
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.
