Tatsuhiro Tsujikawa e85418f045 Fix local window size adjustments
Now shrinking local window size properly limits the amount of
WINDOW_UPDATE value so that shrinked window is honored.

Tatsuhiro Tsujikawa 252c77f775 Return NGHTTP2_ERR_INVALID_STREAM_STATE for DATA, WINDOW_UPDATE to reserved
Use NGHTTP2_ERR_INVALID_STREAM_STATE when trying to send DATA or
WINDOW_UPDATE to reserved stream.
Also a bit refactored nghttp2_session_predicate_window_update_send
and nghttp2_session_predicate_data_send

Tatsuhiro Tsujikawa 21d76dcc75 Add nghttp2_session_continue API function
The NGHTTP2_ERR_PAUSE library error code is introduced to pause
the execution of nghttp2_session_mem_recv() when that error code
is returned from nghttp2_on_frame_recv_callback or
nghttp2_on_data_chunk_recv_callback. If this happens, the parameters
available for both callbacks are retained until the application
calls nghttp2_session_continue(). The application must retain
input bytes which was used to produce the frame.
After successful call of nghttp2_session_continue, the application
can continue to call nghttp2_session_mem_recv() to process
additional data.

Tatsuhiro Tsujikawa 99ba622fed Add NGHTTP2_OPT_PEER_MAX_CONCURRENT_STREAMS option
And utilize it in nghttp to limit initial max concurrent streams.
2013-09-14 19:41:49 +09:00
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.

Daniel Stenberg 96446ff295 libnghttp2.pc: use full name, fix Libs.private
Since the name of the file is 'libnghttp2*' I think we should use the
full name within it as well (for the Name: field), as it gets confusing
otherwise for users and for pkg-config.

Also, 'Requires.private' breaks pkg-config's ability to extract -I etc
from the Cflags below it. I believe it should be 'Libs.private' and the
right side should then list the libs with -l.

With these changes, I've successfully written a configure script to
find and use libnghttp2.

Tatsuhiro Tsujikawa a7bd4f33a3 Call on_stream_close_callback for stream in NGHTTP2_STREAM_INITIAL state
We call on_stream_close_callback even if stream->state is
NGHTTP2_STREAM_INITIAL. This will happen while sending request
HEADERS, a local endpoint receives RST_STREAM for that
stream. It may be PROTOCOL_ERROR, but without notifying stream
closure will hang the stream in a local endpoint.

Tatsuhiro Tsujikawa 19377fb3cd Allow disabling auto WINDOW_UPDATE for connection and stream individually
Now NGHTTP2_OPT_NO_AUTO_WINDOW_UPDATE is split into 2 options:
NGHTTP2_OPT_NO_AUTO_STREAM_WINDOW_UPDATE and
NGHTTP2_OPT_NO_AUTO_CONNECTION_WINDOW_UPDATE.
This is preparation for the upcoming removal of END_FLOW_CONTROL
flag. For nghttpx, instead of using END_FLOW_CONTROL to disable
connection-level flow control, increase window size by large
enough value, which is friendly way to current chromium
implementation.
