Tatsuhiro Tsujikawa c7b0e04498 Add nghttp2_option_set_max_send_header_block_length API function
This function sets the maximum length of header block (a set of header
fields per HEADERS frame) to send.  The length of given set of header
fields is calculated using nghttp2_hd_deflate_bound().  Previously,
this is hard-coded, and is 64KiB.

Tatsuhiro Tsujikawa 2a96d433ec Add nghttp2_hd_inflate_hd2() and deprecate nghttp2_hd_inflate_hd()
The difference between them are former has const qualifier to the |in|
parameter, which is desirable since it is effectively read-only.

Tatsuhiro Tsujikawa 3d948fd3d7 Zero fill in nghttp2_session_mem_send 2016-04-23 00:32:23 +09:00
Mike Conlen e04e24c1c2 in nghttp2_session_send() data is declared uninitialized and used
after a call to nghttp2_session_mem_send_internal() which should
set it, however in nghttp2_session_mem_send_internal() it is
possible to return before setting the pointer.

This change initializes the variable to NULL where delcared and
sets the variable in nghttp2_session_mem_send_internal() to
NULL before possibly returning rather than after.

both options are not necessary but are both ideal practice

Tatsuhiro Tsujikawa e453759637 Add nghttp2_option_set_no_auto_ping_ack() option
This option prevents the nghttp2 library from sending PING frame with
ACK flag set in the reply to incoming PING frame.  To allow the
application to send PING with ACK flag set, nghttp2_submit_ping() now
recognizes NGHTTP2_FLAG_PING in its flags parameter.

Tatsuhiro Tsujikawa 4a78f59e7b Rename nghttp2_session.sent_stream_id as last_sent_stream_id
This is more accurate, and there is symmetric relation between
last_sent_stream_id and last_recv_stream_id, which is bettern fit in
my sense.

Tatsuhiro Tsujikawa 4ceb9fd767 Cancel stream if flow control window gets overflow
Previously, we did terminate session, but it did not actually cancel
streams.  Now we just cancel streams in this case.

Tatsuhiro Tsujikawa 9cea986819 Strict outgoing idle stream detection
Previously, we use session->next_stream_id to detect that given stream
ID was idle or not.  But this was suboptimal, since it was updated
when stream ID was assigned, and it did not necessarily mean that it
actually has been sent to the peer.  Now we introduced
session->sent_stream_id, which only updated when HEADERS/PUSH_PROMISE
has sent.  Using sent_stream_id instead of next_stream_id tightens
idle stream detection, and misbehaved peer which sends frame with
stream ID that has not been generated.

This commit also overhauls test code which involves opening streams.
Now we have some wrapper functions for nghttp2_session_open_stream()
which also take care of updating next_stream_id and
last_recv_stream_id.  They are crucial for some tests.

Tatsuhiro Tsujikawa 894c1bd02e Create idle stream on client side
With the presence of idle stream related API (e.g.,
nghttp2_create_idle_stream()), it is more predictable for client to
create idle streams with its dependency to another idle stream.
Previously, we didn't create complete parent idle stream in this case.
Now we create idle streams as we do on server side.

Tatsuhiro Tsujikawa ca4a40b8e0 Don't schedule response HEADERS with priority tree
Previously we scheduled the transmission of response HEADERS using
priority tree in the belief that it allows more better utilization of
bandwidth for prioritized streams.  But to reduce the overhead of
reconstruction of priority queue when connection level flow control
window is depleted, we just don't check priority tree in this case.
This means that response HEADERS frames are not sent even though they
are not flow controlled.  This could waste bandwidth.  To improve this
situation, we stop scheduling response HEADERS with priority tree for
now.  Now they are just sent in the order they submitted.  The
response body DATA continued to be scheduled with priority tree as
before.

Tatsuhiro Tsujikawa 010726a875 Simplify error handling in nghttp2_session_on_headers_received
return session_inflate_handle_invalid_stream(...) case is for streams
for INITIAL state, but this is rare case.  In general, we'd like to
reduce RST_STREAM transmission, and it is suffice to ignore this frame
for now.
