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.
