This changes the behavior of the ChannelPipeline.remove(..) and ChannelPipeline.replace(..) methods in that way
that after invocation it is not possible anymore to access any data in the inbound or outbound buffer. This is
because it empty it now to prevent side-effects. If a user want to preserve the content and forward it to the
next handler in the pipeline it is adviced to use one of the new methods which where introduced.
- ChannelPipeline.removeAndForward(..)
- ChannelPipeline.replaceAndForward(..)
- Rename message types for clarity
- HttpMessage -> FullHttpMessage
- HttpHeader -> HttpMessage
- HttpRequest -> FullHttpRequest
- HttpResponse -> FulllHttpResponse
- HttpRequestHeader -> HttpRequest
- HttpResponseHeader -> HttpResponse
- HttpContent now extends ByteBufHolder; no more content() method
- Make HttpHeaders abstract, make its header access methods public, and
add DefaultHttpHeaders
- Header accessor methods in HttpMessage and LastHttpContent are
replaced with HttpMessage.headers() and
LastHttpContent.trailingHeaders(). Both methods return HttpHeaders.
- Remove setters wherever possible and remove 'get' prefix
- Instead of calling setContent(), a user can either specify the content
when constructing a message or write content into the buffer.
(e.g. m.content().writeBytes(...))
- Overall cleanup & fixes
This commit tries to simplify the handling of Http easier and more consistent. This has a effect of many channges. Including:
- HttpMessage was renamed to HttpHeader and the setContent and getContent methods were removed
- HttpChunk was renamed to HttpContent
- HttpChunkTrailer was renamed to LastHttpContent
- HttpCodecUtil was merged into HttpHeaders
Now a "complete" Http message (request or response) contains of the following parts:
- HttpHeader (HttpRequestHeader or HttpResponseHeader)
- 0 - n HttpContent objects which contains parts of the content of the message
- 1 LastHttpContent which marks the end of the message and contains the remaining data of the content
I also changed the sematic of HttpResponse and HttpRequest, these now represent a "complete" message which contains the HttpHeader and the HttpLastContent, and so can be used to eeasily send requests. The HttpMessageAggregator was renamed to HttpObjectAggregator and produce HttpResponse / HttpRequest message.
Channel handlers above the HttpEncoder may delay the repsonse being
written to the socket. We need to wait for the response to complete
before upgrading the pipeline.
- Replaced FrameDecoder and OneToOne(Encoder|Decoder) with:
- (Stream|Message)To(String|Message)(Encoder|Decoder)
- Moved the classes in 'codec.frame' up to 'codec'
- Fixed some bugs found while running unit tests
Split the project into the following modules:
* common
* buffer
* codec
* codec-http
* transport
* transport-*
* handler
* example
* testsuite (integration tests that involve 2+ modules)
* all (does nothing yet, but will make it generate netty.jar)
This commit also fixes the compilation errors with transport-sctp on
non-Linux systems. It will at least compile without complaints.
