The spdylay_data contains full of implementation details and is not
used in public API. It should be hidden.
The spdylay_frame union now only contains the control frame.
We say the header block is invalid if at least one of the following
condition is true:
There are duplicate header names; or the header names are not
encoded in US-ASCII character set and not lower cased; or the
header name is zero-length string; or the header value contains
multiple in-sequence NUL bytes.
spdylay_frame_unpack_nv() returns SPDYLAY_ERR_INVALID_HEADER_BLOCK
if the unpacking suceeded but it found the header block is invalid.
This means that caller treats it as success, but do additional
processing for invalid header block if it wants.
The functions calling spdylay_frame_unpack_nv() also return
SPDYLAY_ERR_INVALID_HEADER_BLOCK.
Now remote and local settings are stored separately.
The initial window size is included in SETTINGS frame, all active stream's
window sizes are now updated.
Removed the initial_window_size member from spdylay_stream because
it is the same as remote_settings's initial window size.
This callback function is invoked after the control frame
is not sent because of the error. The error is indicated by
the error argument, which is one of the values defined in spdylay_error.
This function invoked when request from remote peer is
received. In other words, frame with FIN flag set is received. In
HTTP, this means HTTP request, including request body, is fully
received.
If max concurrent streams limit is reached, SYN_STREAM frames are not sent
and backed off. If other type of frame is waiting in the tx queue, it is
sent first. We introduced another priority queue for this purpose.
In this change we did not add code to send RST_STREAM when SYN_STREAM is
received but max concurrent stream is reached.
We use just single buffer to store name/value headers fields, instead of
allocating memory for each name/value strings.
It is now more than 2 times faster than old one.
Specified stream_user_data_arg can be retrieved by
spdylay_session_get_stream_user_data() function. The application code can use
this function insde spdylay_on_ctrl_send_callback() and identify stream ID
for the request associated by the stream_user_data.
The sample usage is in examples/spdycat.cc.
