Tatsuhiro Tsujikawa 727662257c Add missing NGHTTP2_ERR_BAD_PREFACE to nghttp2_strerror 2014-09-17 23:25:47 +09:00
Tatsuhiro Tsujikawa b2f88f8fe3 Fix memory leak around stream->data_item
Previously we missed the case where stream->data_item is not deleted
and it caused leak.  Now stream->data_item is properly deleted when
session is deleted.  We decided not to delete data_item in
nghttp2_stream_free() since we need nghttp2_session to decide whether
data_item should be deleted or not there.

Tatsuhiro Tsujikawa 901de5fbce Add nghttp2_option_set_recv_client_preface()
By default, nghttp2 library only handles HTTP/2 frames and does not
recognize first 24 bytes of client connection preface. This design
choice is done due to the fact that server may want to detect the
application protocol based on first few bytes on clear text
communication. But for simple servers which only speak HTTP/2, it is
easier for developers if nghttp2 library takes care of client
connection preface.

If this option is used with nonzero val, nghttp2 library checks first
24 bytes client connection preface. If it is not a valid one,
nghttp2_session_recv() and nghttp2_session_mem_recv() will return
error NGHTTP2_ERR_BAD_PREFACE, which is fatal error.

Tatsuhiro Tsujikawa b4bb6a6101 Add reserved bits to header and frames
Currently reserved bit is always set to 0.  The addition of reserved
bit is for future extension.

Tatsuhiro Tsujikawa 0b1ab90fb8 Move frame_type parameter in front of stream_id
This commit moves frame_type parameter of
nghttp2_data_soruce_read_length_callback in front of stream_id
parameter.  The motivation is that other callback is generally put
frame related parameters first.  To make it consistent, we move
frame_type, which is frame ralted parameter, to the left.

Tatsuhiro Tsujikawa 93b4d9efc3 Allow application to call nghttp2_submit_data() in on_frame_send_callback
Previously we always call on_frame_send_callback before calling
nghttp2_stream_detach_data() after sending DATA frame.  As a result,
even if DATA frame has END_STREAM, application cannot call
nghttp2_submit_data() in on_frame_send_callback because previous data
is still attached.  This commit makes a change so that
nghttp2_stream_detach_data() is called before on_frame_send_callback
so that application can issue nghttp2_submit_data() in the callback.

Tatsuhiro Tsujikawa 82bc7198e6 Change nghttp2_session_get_stream_remote_window_size behavior
Now it returns only stream's available remote window size, without
considering connection level window size.  For connection-level window
size, nghttp2_session_get_remote_window_size() is added by this
commit.  To get old behavior of
nghttp2_session_get_stream_remote_window_size() is use
min(nghttp2_session_get_stream_remote_window_size(),
nghttp2_session_get_remote_window_size()).  The reason of this change
is that it is desirable to know just stream level window size without
taking into connection level window size.  This is useful for
debugging purpose.

received.

Tatsuhiro Tsujikawa 53ee21caa9 Remove nghttp2_on_unknown_frame_recv_callback
It is not used by library for a while.  It could be used to pass
unsupported extension frames to application, but its interface
requires library to buffer entire frame, which we'd like to avoid.
For unsupported extension frames, we will add new callbacks which does
not require buffering if they are required.

Tatsuhiro Tsujikawa 31528b6267 Use uint32_t for HTTP/2 error_code
h2-14 now allows extensions to define new error codes.  To allow
application callback to access such error codes, we uses uint32_t as
error_code type for structs and function parameters.  Previously we
treated unknown error code as INTERNAL_ERROR, but this change removes
this and unknown error code is passed to application callback as is.

Tatsuhiro Tsujikawa ab5b81bee1 Hide nghttp2_session_callbacks details and provide setter like functions
To make it possible to add new callbacks without bumping so name, we
decided to hide details of nghttp2_session_callbacks.  We provide
setter like functions to set individual callback function.

Scott Mitchell 3cd08251ca Send window size API extension
Motivation:

The send window size is currently fixed by a macro at compile time.
In order for users of the library to impact the send window size they
would have to change a macro at compile time. The window size may be dynamic
depending on the environment and deployment scheme. The library users
currently have no way to change this parameter.

Modifications:

Add a new optional callback method which is called before data is sent to
obtain the desired send window size. The callback return value will be
subject to a range check for the current session, stream, and settings
limits defined by flow control.

Result:
Library users have control over their send sizes.

Tatsuhiro Tsujikawa 7bfa276e96 Fix bug that NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE causes session failure
Previously returning NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE from
on_header_callback moves input offset badly and it causes header
decompression error on the subsequent frames.  This commit fix this
bug.

Tatsuhiro Tsujikawa 00ead22395 Don't allow frame submission for pending new frame
This is partial revert of bbe4f5a3d1.
Only documentation is reverted.  Since we have 2 queues to handle
maximum concurrent streams, we are not ready to allow immediate frame
submission for pending new frames.

Tatsuhiro Tsujikawa bbe4f5a3d1 Allow frame submission immediately after nghttp2_submit_{request,headers,pp}
This commit makes handling of outgoing HEADERS and PUSH_PROMISE in the
same priority of other frames on the stream, so these frames are
processed in the order they are submitted.  This allows application to
submit frames to a stream returned by nghttp2_submit_{request,
headers, push_promise} immediately.  The only exception is
WINDOW_UPDATA frame, which requires nghttp2_stream object, which is
not created yet.
