Tatsuhiro Tsujikawa d56ecd7414 Add nghttp2_session_consume_{connection,stream} to consume bytes independently
The existing nghttp2_session_consume() affects both connection and
stream level flow control windows.  The new functions only affects
either connection or stream.  There is some interesting use cases.
For example, we may want to pause a stream by not sending
WINDOW_UPDATE, meanwhile we want to continue to process other streams.
In this case, we use nghttp2_session_consume_connection() to tell
library that only connection level window is recovered.  The relevant
discussion: https://code.google.com/p/chromium/issues/detail?id=473259

Tatsuhiro Tsujikawa cc03a12b75 Don't call nghttp2_send_data_callback if stream has already closed
This is more inline with other callback function invocations where if
stream was closed, they are not invoked.

Tatsuhiro Tsujikawa 9eff511c5e Add nghttp2_send_data_callback to send DATA payload without copying
To avoid buffer copy in nghttp2_data_source_read_callback, this commit
introduces NGHTTP2_DATA_FLAG_NO_COPY and nghttp2_send_data_callback.
By using NGHTTP2_DATA_FLAG_NO_COPY in
nghttp2_data_source_read_callback, application can avoid to copy
application data to given buffer.  Instead, application has to
implement nghttp2_send_data_callback to send complete DATA frame by
itself.  We see noticeable performance increase in nghttpd and
tiny-nghttpd using this new feature.  On the other hand, nghttpx does
not show such difference, probably because buffer copy is not
bottleneck.  Using nghttp2_send_data_callback adds complexity, so it
is recommended to measure the performance to see whether this extra
complexity worth it.

Tatsuhiro Tsujikawa 87029e05af doc: Split API reference into smaller fine grained files
Previously API reference is gigantic one rst file and it is a bit hard
to use, especially when browsing similar functions.  This commit
splits API reference into smaller fine grained files.  The macros,
enums, types are now in its own file.  Each API function has its own
file now.  API reference doc is now index to above documentation
files.  The apiref-header.rst is renamed as programmers-guide.rst and
becomes standalone document.

Tatsuhiro Tsujikawa dd9e829ee1 Document NGHTTP2_DATA_FLAG_NO_END_STREAM in nghttp2_data_source_read_callback 2015-03-07 17:59:58 +09:00
Tatsuhiro Tsujikawa 2f2a535113 Add a way to send trailer with nghttp2_submit_request/nghttp2_submit_response
nghttp2_submit_request and nghttp2_submit_response will set
NGHTTP2_FLAG_END_STREAM after all given data is sent (data could be
0).  This means we have no way to send trailers.  In this commit, we
added NGHTTP2_DATA_FLAG_NO_END_STREAM flag.  The application can set
this flag in *data_flags inside nghttp2_data_source_read_callback.  If
NGHTTP2_DATA_FLAG_EOF is set, library automatically set
NGHTTP2_FLAG_END_STREAM.  But if both NGHTTP2_DATA_FLAG_EOF and
NGHTTP2_DATA_FLAG_NO_END_STREAM are set, NGHTTP2_FLAG_END_STREAM will
not set by library.  Then application can use new
nghttp2_submit_trailer() to send trailers.  nghttp2_submit_trailer()
will set NGHTTP2_FLAG_END_STREAM and it is actually thing wrapper of
nghttp2_submit_headers().

Tatsuhiro Tsujikawa 505a300d93 Refuse PUSH_PROMISE while unacked local ENABLE_PUSH is 0
After we sent SETTINGS including ENABLE_PUSH = 0, peer may already
issue PUSH_PROMISE before receiving our SETTINGS and react it to
SETTINGS ACK.  Previously we accept this PUSH_PROMISE.  In this
commit, we check the pending ENABLE_PUSH value and if it means
disabling push, we refuse PUSH_PROMISE with RST_STREAM of error
REFUSED_STREAM.

Tatsuhiro Tsujikawa 814c7e68e0 Ignore regular headers if it includes illegal characters.
This commit only affects the library behaviour unless
nghttp2_option_set_no_http_messaging() is used.

We like strict validation against header field name and value against
RFC 7230, but we have already so much web sites and libraries in
public internet which do not obey these rules.  Simply just
terminating stream because of this may break web sites and it is too
disruptive.  So we decided that we should be conservative here so
those header fields containing illegal characters are just ignored.
But we are conservative only for regular headers.  We are strict for
pseudo headers since it is new to HTTP/2 and new implementations
should know the rules better.

Tatsuhiro Tsujikawa b157d4ebb2 Validate HTTP semantics by default
Previously we did not check HTTP semantics and it is left out for
application.  Although checking is relatively easy, but they are
scattered and error prone.  We have implemented these checks in our
applications and also feel they are tedious.  To make application
development a bit easier, this commit adds basic HTTP semantics
validation to library code.  We do following checks:

server:

* HEADERS is either request header or trailer header.  Other type of
header is disallowed.

client:

* HEADERS is either zero or more non-final response header or final
  response header or trailer header.  Other type of header is
  disallowed.

For both:

* Check mandatory pseudo header fields.
* Make sure that content-length matches the amount of DATA we
  received.

If validation fails, RST_STREAM of type PROTOCOL_ERROR is issued.

Tatsuhiro Tsujikawa 442572c1f4 Handle situation where request HEADERS in queue is reset by RST_STREAM
Previously we did not handle the situation where RST_STREAM is
submitted against a stream while requet HEADERS which opens that
stream is still in queue.  Due to max concurrent streams limit,
RST_STREAM is sent first, and then request HEADERS, which effectively
voids RST_STREAM.

In this commit, we checks RST_STREAM against currently pending request
HEADERS in queue and if stream ID matches, we mark that HEADERS as
canceled and RST_STREAM is not sent in this case.  The library will
call on_frame_not_sent_callback for the canceled HEADERS with error
code from RST_STREAM.

Tatsuhiro Tsujikawa 354de30874 Make default min frame payload size to 16K
Previously we use 16K - 9 bytes (frame header) as frame payload size
so that whole frame fits in 1 TLS record size (16K).  But it turns out
that in proxy use case, we will receive 16K payload from backend and
we have to split it into 2 odd looking frames (16K - 9 and 9), and
latter is highly inefficient.  To avoid this situation, we decided to
use min frame payload size to 16K.  Since we operates on TLS as stream
of data, we are not so much restricted in its record size.
