Motivation:
Need to upgrade HTTP/2 implementation to latest draft.
Modifications:
Various changes to support draft 13.
Result:
Support for HTTP/2 draft 13.
Motivation:
Draft 12 has just arrived and has quite a few changes. Need to update in
order to keep current with the spec.
Modifications:
This is a rewrite of the original (draft 10) code. There are only 2
handlers now: preface and connection. The connection handler is now
callback based rather than frame based (there are no frame classes
anymore). AbstractHttp2ConnectionHandler is the base class for any
HTTP/2 handlers. All of the stream priority logic now resides in the
outbound flow controller, and its interface exposes methods for
adding/updating priority for streams.
Upgraded to hpack 0.7.0, which is used by draft12. Also removed
draft10 code and moved draft12 code to the ../http2 package
(no draft subpackage).
Result:
Addition of a HTTP/2 draft 12 support.
Motivation:
The use of the guava library library is fairly superficial and can
easily be removed to reduce the overall dependency list of the module.
Cleaning up the HTTP2 code to use common Netty utilities, etc.
Modifications:
- Various changes to remove use of guava preconditions and collections.
- Changed default charset to use CharsetUtil.UTF_8.
- Changed StreamState to use ArrayDeque instead of LinkedList.
- Changed precondition checks to throw NPE
- Changed implementation of Http2Headers to more closely mirror the SPDY
implementation.
Result:
The behavior of the HTTP2 module will remain unchanged.
Motivation:
Needed a rough performance comparison between SPDY and HTTP 2.0 framing.
Expected performance gains were seen in HTTP 2.0 due to header
compression.
Modifications:
Added a new codec-http2 module containing all of the new source and unit
tests. Updated the top-level pom.xml to add this as a child module.
Result:
Netty will have basic support for HTTP2.
