We do -+1 on serialization and deserialization since the field is 1
byte.  This change also parameterized range so that we can change it

Tatsuhiro Tsujikawa 3395f7158f Strict handling of max concurrent streams
Exceeding ACKed max concurrent streams results in connection error.
This change fixes the bug that num_{incoming,outgoing}_streams
is decremented wrongly if a stream is in reserved state and
RST_STREAM is send and its state is changed to NGHTTP2_STREAM_CLOSING.
This change also fixes the bug that transmission of push response
HEADERS does not increase num_outgoing_streams.

serialized data to trasmit and its length to the caller.

Tatsuhiro Tsujikawa 1e95c8b313 Allow always max 1024 padding for HEADERS
We need paddings regardless of payload and frame boundary to mitigate
certain attacks.

Since we handles CONTINUATION internally, we don't show FLAG_PAD_HIGH
and PAD_LOW flags of HEADERS in nghttp/nghttpd. We just show the
total paddings in HEADERS + CONTINUATION.

Tatsuhiro Tsujikawa 78d202ac30 Callback based padding from application
Now previous padding options are removed and instead we added
select_padding_callback to select padding length for each frame
by application. If this callback is not implemented by application,
no padding is added.

This change also fixes the broken session_detect_idle_stream()
if stream_id is our side.

Tatsuhiro Tsujikawa ab684a9f30 Remove nghttp2_on_request_recv_callback
It is easy enough to check the end of incoming data by evaluating

2014-01-29 21:56:01 +09:00
Tatsuhiro Tsujikawa bbdc015e84 Call on_frame_recv_callback for DATA even if stream has been closed
This makes the callback semantics consistent with the other
frames like HEADERS/PUSH_PROMISE.
2014-01-29 21:34:48 +09:00
Tatsuhiro Tsujikawa e186e01933 Replace on_end_headers_callback with on_begin_headers_callback
Previously, there is inconsistency when on_frame_recv_callback
is called between HEADERS/PUSH_PROMISE and the other frames.
For former case, it is called before header block, in latter
case, it is called after whole frame is received. To make it
consistent, we call on_frame_recv_callback for HEADERS/PUSH_PROMISE
after its frame is fully received. Since on_frame_recv_callback
can signal the end of header block, we replaced on_end_headers_callback
with on_begin_headers_callback, which is called when the reception
of the header block is started.

nghttp2_data is added to nghttp2_frame union. When DATA is
received, nghttp2_on_frame_recv_callback is called. When DATA is
sent, nghttp2_on_frame_send_callback is called.

Tatsuhiro Tsujikawa dba2406aba nghttp2_sesson_mem_recv: Process incoming data in streaming fashion
Now incoming data is processed in very small buffer (up to 8 bytes)
using state machine. GOAWAY debug data can get to 16K - 1, and we
don't have callback for it. Since we don't want to buffer that
amount of data just for debugging, we currently discard it.
This change also makes parse_error callback not function.
It probably be removed from API.

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 41104f7b63 Abandon DATA frame priority adjustment (again)
We tried several times about this subject, but for the current
HTTP/2.0 priority scheme, we think it is best to serve the highest
priroty streams first (interleaving streams if there are several
higest ones). There are an issue when aggregating several frontend
connections to one connection in backend, but it is HTTP/2.0
spec issue, rather than implementation.

Tatsuhiro Tsujikawa 364501a2cd Get rid of magic value NGHTTP2_PRI_DECAY
For now we just double the priority value on each DATA frame

Tatsuhiro Tsujikawa 5044b59453 Handle error from nghttp2_session_push_back_deferred_data 2013-11-12 10:44:04 +09:00
Tatsuhiro Tsujikawa 2ae788eddd Replace nghttp2_set_option with nghttp2_session_{client,server}_new2
nghttp2_session_client_new2 and nghttp2_session_server_new2 take
additional parameters which specifies session options.
nghttp2_set_option is somewhat crumsy because of type checking.
Now we use nghttp2_opt_set, which specifies individual options with
types. We changed the value of nghttp2_opt, so this change will
require re-compile.

Tatsuhiro Tsujikawa 4bc44b0c0b Implement SETTINGS_ENABLE_PUSH
It is not clear that SETTINGS_ENABLE_PUSH = 0 disallows HEADERS
to the reserved streams. For now, we just check the reception
and transmission of PUSH_PROMISE against SETTINGS_ENABLE_PUSH.

Tatsuhiro Tsujikawa dfa1194804 Add new API to return effective recv data/win size for connection
Using this feature, connection level flow control is now enabled
in nghttpx.

Tatsuhiro Tsujikawa a4cf37306a Enfoce flow control error strictly
Now we have SETTINGS synchronization, flow control error can be
detected strictly. If DATA frame is received with length > 0 and
current received window size is equal to or larger than local
window size (latter happens when we shirnk window size), it is
subject to FLOW_CONTROL_ERROR,

Tatsuhiro Tsujikawa 896db5b24f API change: Add flags parameter to all submit_* functions
The nghttp2_submit_{request,response} family do not get this change.

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 0efa6e657f Fix outbound flow control count
We wrongly added the whole payload length even if we sent part of it.

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.

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 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.
