Tatsuhiro Tsujikawa e5abc475f1 Don't send more than NGHTTP2_MAX_HEADERSLEN bytes header block 2014-07-02 22:45:38 +09:00
Tatsuhiro Tsujikawa 593485c652 Put a limit for total contiguous headers length currently receiving 2014-07-02 22:25:32 +09:00
Tatsuhiro Tsujikawa 6da044cbb5 Send WINDOW_UPDATE for ignored DATA bytes when manual flow control is enabled
Since we do not call on_data_chunk_recv_callback for ignored DATA
chunk, if nghttp2_option_set_no_auto_connection_window_update is used,
application may not have a chance to send connection WINDOW_UPDATE.
To fix this, we accumulate those received bytes, and if it exceeds
certain number, we automatically send connection-level WINDOW_UPDATE.

Tatsuhiro Tsujikawa d318e6a62e Support one header field size (name + value) up to 64KiB by default
This commits changes the upper bound of one header field size (the sum
of the length of name and value) to 64KiB by default.  We may add an
option to change this upper bound in the future.

Tatsuhiro Tsujikawa dacc9b2f1c Separate extension frames from core frames
ALTSVC and BLOCKED frames are now extension frames.  To add new
extension frame without modifying nghttp2_frame union, which causes so
name bump, we separated extension frames from core frames.
nghttp2_frame includes generic nghttp2_extension.  The payload member
of nghttp2_extension will point to the structure of extension frame
payload.  The frame types of extension frames are defined in
nghttp2_ext_frame_type.

Tatsuhiro Tsujikawa 1ac028e166 Take into account that pending_local_max_concurrent_stream could be too large
pending_local_max_concurrent_stream is, once local settings applied,
becomes NGHTTP2_INITIAL_MAX_CONCURRENT_STREAMS, which is very large
number.  When adjusting number of streams, we have to take min of
local effective SETTINGS_MAX_CONCURRENT_STREAMS and pending one.

Hide NGHTTP2_MAX_HEADER_TABLE_SIZE from public API.  Now it is defined
as ((1u << 31) - 1) in nghttp2_frame.h, which is sufficiently big
enough.

Tatsuhiro Tsujikawa 3e3d51842b Interleave stream DATA more naturally
We simulate resource sharing by decreasing weight.  The thing is if
weight is wrapped, that item continues to send DATA until its weight
gets lowered under the other items.  This commits fix this issue.

Tatsuhiro Tsujikawa d2890dfb91 Remove adjust_priority_callback
Since we have stream ID immediately available from nghttp2_submit_*,
we don't need adjust_priority_callback.

Tatsuhiro Tsujikawa e8de437d5c Return new stream ID from nghttp2_submit_{request, headers, push_promise}
Previously stream ID was assigned just before HEADERS or PUSH_PROMISE
was serialized and nghttp2_submit_{request, headers, push_promise} did
not return stream ID.  The application has to check assigned stream ID
using before_frame_send_callback.  Now it is apparent that priority is
meant to DATA transfer only.  Also application can reorder the
requests if it wants. Therefore we can assign stream ID in
nghttp2_submit_* functions and return stream ID from them.  With this
change, now application does not have to check stream ID using
before_frame_send_callback and its code will be simplified.

Tatsuhiro Tsujikawa f207089604 Update doc 2014-05-06 18:34:48 +09:00
Tatsuhiro Tsujikawa 9125499dd0 src: Implement per-frame DATA compression
Currently, nghttpd server only compresses files whose extensions are
one of .html, .js, .css and .txt.  nghttp advertises its support of
per-frame compression in SETTINGS frame.  To implement this feature,
we added 2 public API: nghttp2_session_get_remote_settings() and
nghttp2_gzip_inflate_finished().

Tatsuhiro Tsujikawa 6d5f402380 Add nghttp2_adjust_priority_callback
Callback function invoked to adjust priority value for request
HEADERS.

Since the application doesn’t know stream ID when it submits
requests, it may not be able to add correct priority value to HEADERS
frame and forced to use follwing PRIORITY frame. The purpose of this
callback is give the chance to the application to adjust priority
value with the latest information it has just before transmission so
that correct priority is included in HEADERS frame and it doesn’t
have to send additional PRIORITY frame.

Tatsuhiro Tsujikawa 052be3296c Implement compressed DATA
The library interface supports compressed DATA.  The library does not
deflate nor inflate data payload.  When sending data, an application
has to compress data and set NGHTTP2_DATA_FLAG_COMPRESSED to
data_flags parameter in nghttp2_data_source_read_callback.  On
receiving, flags parameter in nghttp2_on_data_chunk_recv_callback
includes NGHTTP2_FLAG_COMPRESSED.  An application should check the
flags and inflate data as necessary.  Since compression context is per
frame, when DATA is seen in nghttp2_on_frame_recv_callback, an
application should reset compression context.
