Tatsuhiro Tsujikawa 4bcc14fc67 Reschedule stream when only weight is changed
Previously, we only updated stream's weight field when only weight was
changed by PRIORITY frame.  If stream is queued, it would be better to
actually reschedule it based on new weight.  This could be especially
useful if weight is increased.

Tatsuhiro Tsujikawa 72f815d535 Update descendant_last_cycle on nghttp2_stream_next_outbound_item
Previously, we updated descendant_last_cycle in
nghttp2_stream_reschedule, which is called after non-zero DATA frame.
But this was not optimal since we still had old descendant_last_cycle,
and new stream was scheduled based on it.  Now descendant_last_cycle
is updated in nghttp2_stream_next_outbound_item, which is called when
stream with highest priority is selected from queue.  And new stream
is scheduled based on it.  This commit also removes 0-reset of
descendant_last_cycle and cycle in nghttp2_stream_reschedule.  This
could help making them lower, so that they are not overflow.  But
there is a pattern that it doesn't work, and we are not sure they are
really useful at this moment.

We should only keep incoming closed streams because we only keep at
most max concurrent streams, which only applied to incoming streams.

Tatsuhiro Tsujikawa 2288ee8060 Create stream object for pushed resource during nghttp2_submit_push_promise()
Previously, stream object for pushed resource was not created during
nghttp2_submit_push_promise().  It was created just before
nghttp2_before_frame_send_callback was called for that PUSH_PROMISE
frame.  This means that application could not call
nghttp2_submit_response for the pushed resource before
nghttp2_before_frame_send_callback was called.  This could be solved
by callback chaining, but for web server with back pressure from
backend stream, it is a bit unnecessarily hard to use.

This commit changes nghttp2_submit_push_promise() behaviour so that
stream object is created during that call.  It makes application call
nghttp2_submit_response right after successful
nghttp2_submit_push_promise call.

Tatsuhiro Tsujikawa f23e34fa3c Handle response in nghttp2_on_begin_frame_callback
Previously, nghttp2_session_end_request_headers_received assumes
stream is still writable (in other words, local endpoint has not sent
END_STREAM).  But this assumption is false, because application can
send response in nghttp2_on_begin_frame_callback.  Probably, this
assumption was made before the callback was introduced.  This commit
addresses this issue.  Since all
nghttp2_session_end_*_headers_received functions are identical, we
refactored them into one function.

Tatsuhiro Tsujikawa faad041868 Use seq to break a tie for stream weight
Because of the nature of heap based priority queue, and our compare
function, streams with the same weight and same parent are handled in
the reverse order they pushed to the queue.  To allow stream pushed
earlier to be served first, secondary key "seq" is introduced to break
a tie.  "seq" is monotonically increased integer per parent stream,
and it is assigned to stream when it is pused to the queue, and gets
incremented.

Tatsuhiro Tsujikawa aa317c89ea Add API to change stream priority without sending PRIORITY frame
The added API is nghttp2_session_change_stream_priority().  This
provides the same functionality to re-prioritize stream when PRIORITY
frame.  is received, but we do it without PRIORITY frame.  This could
be useful for server to change pushed stream's priority silently.

Tatsuhiro Tsujikawa 4db3828fa6 Reset last_writelen to 0 when stream is removed from tree
When stream is removed from tree, stream is either closed, or its
remote flow control window is depleted.  In the latter case, we
schedule this stream as fast as possible if its remote window gets
positive, since it did not sent anything in its turn.  To achieve
this, reset last_writelen to 0 when stream is removed from tree.

Tatsuhiro Tsujikawa b95a3c4b28 Consider to use CANCEL error code when closing streams with GOAWAY
For clients, CANCEL is more appropriate for both incoming/outgoing

stream.

Tatsuhiro Tsujikawa 269a100081 Add nghttp2_session_upgrade2(), deprecate nghttp2_session_upgrade()
To validate actual response body length against the value declared in
content-length response header field, we first check request method.
If request method is HEAD, respose body must be 0 regardless of the
value in content-length.  nghttp2_session_upgrade() has no parameter
to indicate the request method is HEAD, so we failed to validate
response body if HEAD is used with HTTP Upgrade.  New
nghttp2_session_upgrade2() accepts new parameter to indicate that
request method is HEAD or not to fix this issue.  Although, this issue
affects client side only, we deprecate nghttp2_session_upgrade() in
favor of nghttp2_session_upgrade2() for both client and server side.
2015-11-07 16:13:06 +09:00
Tatsuhiro Tsujikawa 5e7e479c6c Workaround HTTP upgrade with HEAD request
By default, we check the length of response body matches
content-length.  For HEAD request, this is not necessarily true, so we
sniff request method, and if it is HEAD, make sure that response body
length is 0.  But this does not work for HTTP Upgrade, since
nghttp2_session_upgrade() has no parameter to tell the request method
was HEAD.  This commit disables this response body length validation
for the stream upgraded by HTTP Upgrade.  We will add new version of
nghttp2_session_upgrade with the parameter to pass the request method
information so that we can handle this situation properly.

Tatsuhiro Tsujikawa 58d636abdb Revert 918f8cca36
For first scheduling, we might ignore weight.  This is OK since weight
is just a distribution of resource, rather than strict priority
ordering.

is not sent.

Tatsuhiro Tsujikawa 928a81885c Limit the number of incoming reserved (remote) streams
RFC 7540 does not enforce any limit on the number of incoming reserved
streams (in RFC 7540 terms, streams in reserved (remote) state).  This
only affects client side, since only server can push streams.
Malicious server can push arbitrary number of streams, and make
client's memory exhausted.  The new option,
nghttp2_set_max_reserved_remote_streams, can set the maximum number of
such incoming streams to avoid possible memory exhaustion.  If this
option is set, and pushed streams are automatically closed on
reception, without calling user provided callback, if they exceed the
given limit.  The default value is 200.  If session is configured as
server side, this option has no effect.  Server can control the number
of streams to push.

Tatsuhiro Tsujikawa 5b59e46e2b Rewrite priority handling
We now use priority queue per stream, which contains the stream which
has ready to send a frame, or one of its descendants have a frame to
send.  We maintain invariant that if a stream is queued, then its
ancestors are also queued (except for root).  When we re-schedule
stream after transmission, we re-schedule all ancestors, so that
streams on the other path can get a chance to send.  This is basically
the same mechanism h2o project uses, but there are differences in the
details.

Previously, the number of stream in one dependency tree (not including

recursive calls to traverse trees.  Now we replaced recursive calls
with loop, we can remove this limitation.  Also now all streams are
descendant of root stream, rather than linked list of individual
subtree root.

RFC 7541 requires that dynamic table size update must occur at the

table size update appears other than the beginning of the first header
block, it is treated as error.  If SETTINGS ACK is received, and next
HEADERS header block does not have dynamic table size update, it is
treated as error.

Tatsuhiro Tsujikawa a7031da364 Fix bug that idle self-depending PRIORITY is not handled gracefully
Previously, we did not handle PRIORITY frame which depends on itself
and for idle stream.  As a result, nghttp2_session_mem_recv (or
nghttp2_session_recv) returne NGHTTP2_ERR_NOMEM.  The error code was
still misleading.  It was not out of memory, and we failed to insert
hash map because of duplicated key, which was treated as out of
memory.  This commit fixes this issue, by explicitly checking
dependency for incoming PRIORITY for all cases.

While this commit optimizes dependency routine to Firefox style tree,
the other use cases (e.g., linear chain) are also improved
dramatically as well.

Tatsuhiro Tsujikawa b5717cd288 Fix bug that data are not consumed for connection in race condition
When we know that stream is closed at time we read DATA frame header,
we use NGHTTP2_IB_IGN_DATA, and consume data for connection if
nghttp2_option_set_no_auto_window_update() is used.  However, if
stream is closed while we are in NGHTTP2_IB_READ_DATA, those bytes are
not consumed for connection, nor notified to application via callback,
so it eventually fills up connection window and connection will
freeze.  This commit fixes this issue by consuming these data for
connection when stream is closed or does not exist.

.dll), and not part of public API.  It could be removed in the future
release.

Tatsuhiro Tsujikawa 53bfc70c9e Include inttypes.h (or cintypes for C++) instead of stdint.h
From autoconf manual, section 5.6.1 Portability of Headers, says:

"""
The C99 standard says that inttypes.h includes stdint.h, so there's no
need to include stdint.h separately in a standard environment. Some
implementations have inttypes.h but not stdint.h (e.g., Solaris 7),
but we don't know of any implementation that has stdint.h but not
inttypes.h.

Tatsuhiro Tsujikawa f2cf2b625c Replace priority queue with linear queue where possible
After reviewing codebase, only queue for DATA frames requires
priorities.  Other frames can be replaced multiple linear queues.
Replacing priority queue with linear queue allows us to simplify
codebase a bit; for example, now nghttp2_session.next_seq is gone.

Tatsuhiro Tsujikawa 514558afc0 Allow NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE from nghttp2_on_begin_headers_callback
Since application most likely allocates the stream object in
nghttp2_on_begin_headers_callback, it is desirable to handle its
failure as stream error.  But previously it only signals success or
fatal error.  Submitting RST_STREAM does not prevent
nghttp2_on_header_callback from being invoked.  This commit improves
this situation by allowing NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE from
nghttp2_on_begin_headers_callback.  If that value is returned, library
submits RST_STREAM with error code INTERNAL_ERROR, and
nghttp2_on_header_callback and nghttp2_on_frame_recv_callback for that
frame are not invoked.  Note that for PUSH_PROMISE frame, the stream
to be reset is promised stream.
