Tatsuhiro Tsujikawa 2a96d433ec Add nghttp2_hd_inflate_hd2() and deprecate nghttp2_hd_inflate_hd()
The difference between them are former has const qualifier to the |in|
parameter, which is desirable since it is effectively read-only.

Tatsuhiro Tsujikawa 3d948fd3d7 Zero fill in nghttp2_session_mem_send 2016-04-23 00:32:23 +09:00
Mike Conlen e04e24c1c2 in nghttp2_session_send() data is declared uninitialized and used
after a call to nghttp2_session_mem_send_internal() which should
set it, however in nghttp2_session_mem_send_internal() it is
possible to return before setting the pointer.

This change initializes the variable to NULL where delcared and
sets the variable in nghttp2_session_mem_send_internal() to
NULL before possibly returning rather than after.

both options are not necessary but are both ideal practice

Peter Wu 7f8110601e cmake: fix compatibility with cmake before 3.3
The COMPILE_LANGUAGE generator expression is only supported since CMake
3.3. Moreover, it does not work with all generators (works with Makefile
and Ninja, but not with Visual Studio).

target_compile_options would only work if a target does not mix C and
C++ sources, since the flags are intended to be set for a specific
language, use set_source_files_properties instead. This approach is also
less repetitive.

Drop the idea of using lists and COMPILE_OPTIONS,
set_source_files_properties only understands COMPILE_FLAGS (a single
string, not a list).

Peter Wu 77e8190b6c cmake: fix symbol visibility issues

Peter Wu 8c46d9181f cmake: process tests directory
Split the nghttp2 library into objects and a shared library from those
objects. This is needed because of symbol visibility. An advantage over
the autotools build is that there are no worries about static versus
static library builds.

Test:

    cmake $srcdir
    make nghttpx-unittest main failmalloc
    make test

Tatsuhiro Tsujikawa bb6f842b37 Check request/response submission error based side of session
Disallow request from server, and response from client respectively.
When the violation is detected, return NGHTTP2_ERR_PROTO from
nghttp2_submit_request, nghttp2_submit_response,
nghttp2_submit_headers.

We also did some refactoring, and now self-dependency detection is
placed where it is only required.

Tatsuhiro Tsujikawa 9cea986819 Strict outgoing idle stream detection
Previously, we use session->next_stream_id to detect that given stream
ID was idle or not.  But this was suboptimal, since it was updated
when stream ID was assigned, and it did not necessarily mean that it
actually has been sent to the peer.  Now we introduced
session->sent_stream_id, which only updated when HEADERS/PUSH_PROMISE
has sent.  Using sent_stream_id instead of next_stream_id tightens
idle stream detection, and misbehaved peer which sends frame with
stream ID that has not been generated.

This commit also overhauls test code which involves opening streams.
Now we have some wrapper functions for nghttp2_session_open_stream()
which also take care of updating next_stream_id and
last_recv_stream_id.  They are crucial for some tests.

Tatsuhiro Tsujikawa 8716dd05d4 Return error from nghttp2_submit_{headers,request} when self dependency is made
Return NGHTTP2_ERR_INVALID_ARGUMENT from nghttp2_submit_headers() if
given stream ID and pri_spec->stream_id are the same (thus trying to
depend on itself).

Also return NGHTTP2_ERR_INVALID_ARGUMENT from nghttp2_submit_request()
and nghttp2_submit_headers() with stream_id == 1, when new stream ID
equals to pri_spec->stream_id.

Previously, these cases are not checked, and just sent to peer.

Tatsuhiro Tsujikawa 894c1bd02e Create idle stream on client side
With the presence of idle stream related API (e.g.,
nghttp2_create_idle_stream()), it is more predictable for client to
create idle streams with its dependency to another idle stream.
Previously, we didn't create complete parent idle stream in this case.
Now we create idle streams as we do on server side.

Tatsuhiro Tsujikawa ca4a40b8e0 Don't schedule response HEADERS with priority tree
Previously we scheduled the transmission of response HEADERS using
priority tree in the belief that it allows more better utilization of
bandwidth for prioritized streams.  But to reduce the overhead of
reconstruction of priority queue when connection level flow control
window is depleted, we just don't check priority tree in this case.
This means that response HEADERS frames are not sent even though they
are not flow controlled.  This could waste bandwidth.  To improve this
situation, we stop scheduling response HEADERS with priority tree for
now.  Now they are just sent in the order they submitted.  The
response body DATA continued to be scheduled with priority tree as
before.

Tatsuhiro Tsujikawa 4bcc14fc67 Reschedule stream when only weight is changed
Previously, we only updated stream's weight field when only weight was

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.

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 b53b1381b7 Fix bug that nghttp2_session_find_stream(session, 0) returned NULL
Previously, nghttp2_session_find_stream(session, 0) returned NULL
despite the fact that documentation said that it should return root
stream.  Now it is corrected, and it returns root stream as
documented.

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.

later.  Possibly feature bloat.

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.

there is zero chance to make a request.

This commit also set error_code passed to
nghttp2_on_stream_close_callback to NGHTTP2_REFUSED_STREAM if request
is not sent.

This is useful if application writes to fixed sized buffers, and there
is no room to write more data.
