Roland Weber updated HTTPCORE-110:
----------------------------------

    Attachment: 2k7-08-23-parser-2.txt

Here's the next step. The header section parsing has been moved into a separate 
class, which is stateful. The class basically encapsulates the parsing logic 
found in nio.AbstractMessageParser. With respect to object creations, for 
blocking IO the change should be neutral for the message head and add one 
object per footer section being received.
The same interface and class can be used for NIO in AbstractMessageParser and 
ChunkedInput, where it would add one object creation per message and footer, 
respectively. The logic there is a bit intricate though, I would prefer not to 
change it myself.

If I hear no complains by tomorrow evening (CET), I will commit this patch and 
proceed with subsequent cleanup.

cheers,
  Roland

> The line-level parsing and formatting for HTTP messages is spread across 
> static helper methods in o.a.h.message. Refactor the code to allow for easy 
> replacement of these parser and formatter elements, which are used by both 
> core and NIO.
> Ideally, handling of header continuation lines, which is currently still 
> implemented in specific parsers for blocking and NIO, could be factored out 
> too. That would require a stateful parser.
