Tatsuhiro Tsujikawa e7fc2951b8 nghttp2_hd: Define dedicated struct for HPACK deflater and inflater 2014-01-26 17:53:04 +09:00
Tatsuhiro Tsujikawa 8317559090 nghttp2_hd: Implement stream header inflater
This stream inflater can inflate incoming header block in streaming
fashion. Currently, we buffer up single name/value pair, but we chose
far more smaller buffer size than HTTP/2 frame size.

Tatsuhiro Tsujikawa 0e4b3d435e Emit header name/value pair using callback functions
Now, in nghttp2_on_frame_recv_callback, nva and nvlen in
HEADERS and PUSH_PROMISE frames are always NULL and 0 respectively.
The header name/value pairs are emitted successive
nghttp2_on_header_callback functions. The end of header fields are
signaled with nghttp2_on_end_headers_callback function.

Since NGHTTP2_ERR_PAUSE for nghttp2_on_frame_recv_callback is
introduced to handle header block, it is now deprecated.
Instead, nghttp2_on_header_callback can be paused using
NGHTTP2_ERR_PAUSE.

Tatsuhiro Tsujikawa 94ec4dbe42 nghttpd_hd: Update static table and use 1-based index
The specification now says that index to the header table entry is
1-based. Since 0-based index is very handy to access arrays, we
internally uses 0-based index. We just convert it to 1-based when
we emit to the block and convert 1-based to 0-based on decoding.

Tatsuhiro Tsujikawa 40347487c9 Don't sort headers in library code
Remove sorting headers from library code. The application must sort
them if necessary. nghttpx and nghttpd do the sorting of the headers
in stable way if names are equal.

Tatsuhiro Tsujikawa 9e50ae46d9 nghttp_hd: Use NGHTTP2_HD_SIDE_{REQUEST,RESPONSE} instead of {CLIENT,SERVER}
This change conveys better notion about compression context.

Tatsuhiro Tsujikawa 50cdcca911 Implement static Huffman for header compression
The current implementation uses Huffman code tables described
in http://tools.ietf.org/html/draft-rpeon-httpbis-header-compression-03

Tatsuhiro Tsujikawa 94263216fb Add nghttp2_submit_request2
This function is similar to nghttp2_submit_request and the
difference is it takes an array of nghttp2_nv as name/value pairs.
It is useful if name/value pairs is not NULL-terminated in the
application code.

Tatsuhiro Tsujikawa 4dcf9ad4f2 Make hd encoder ordering aware and one-pass
The encoder algorithm is simplified and it now preserves ordering
of the headers. It also becomes one-pass encoder.
