Tatsuhiro Tsujikawa 9314e30987 Support transmission of CONTINUATION, change nghttp2_frame_hd
The maximum frame size including header block is still limited
to NGHTTP2_HD_MAX_BUFFER_LENGTH, which is 32KB.

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 073e6d3a01 nghttp2_hd: Remove unused variables 2014-01-17 09:36:38 +09:00
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 9eb031ce83 nghttp2_hd: Avoid nghttp2_hd_huff_decode_count
Huffman decoding is costly. It is faster to do geometric realloc
than calling nghttp2_hd_huff_decode_count to know the length in
advance.

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.

Instead of emitting common headers on decoder side, encoder
now keeps track of removed common headers and encode it
as necessary.
