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.

The private global variable nghttp2_enable_strict_preface is also
marked as NGHTTP2_EXTERN, but it is test purpose only (test with
.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 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.

Tatsuhiro Tsujikawa 93afbc7d2f Rewrite static header table handling
We rewrite static header table handling in nghttp2_hd.c.  We expand
nghttp2_token to include all static header table entries, and fully
use them in header compression and decompression.  The lookup function
is now located in nghttp2_hd.c.  We add new nghttp2_hd_inflate_hd2()
function to export token value for header name, then we pass it to
nghttp2_http_on_header function, so that we don't have to look up
token there.  We carefully set enum value of token to static table
index, so looking up static table is now O(1), assuming we have token.

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

Tatsuhiro Tsujikawa d0c27d5229 Send 24 bytes client magic byte string by library
Previously nghttp2_session_send() and nghttp2_session_mem_send() did
not send 24 bytes client magic byte string (MAGIC).  We made
nghttp2_session_recv() and nghttp2_session_mem_recv() process MAGIC by
default, so it is natural to make library send MAGIC as well.  This
commit makes nghttp2_session_send() and nghttp2_session_mem_send()
send MAGIC.  This commit also replace "connection preface" with
"client magic", since we call MAGIC as "connection preface" but it is
just a part of connection preface.  NGHTTP2_CLIENT_CONNECTION_PREFACE
macro was replaced with NGHTTP2_CLIENT_MAGIC.  The already deprecated
NGHTTP2_CLIENT_CONNECTION_HEADER macro was removed permanently.
nghttp2_option_set_no_recv_client_preface() was renamed as
nghttp2_option_set_no_recv_client_magic().  NGHTTP2_ERR_BAD_PREFACE
was renamed as NGHTTP2_ERR_BAD_CLIENT_MAGIC.

nghttp2_option_set_no_recv_client_preface().

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 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 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.

Tatsuhiro Tsujikawa eec8870ac1 Fix bug that client may send PROTOCOL_ERROR upon canceled push stream
Previously we treat stream in NGHTTP2_STREAM_RESERVED state specially,
that is we don't increment or decrement streams counts if stream is in
that state.  Because of this, we don't change the stream state to
NGHTTP2_STREAM_CLOSING if stream is in NGHTTP2_STREAM_RESERVED.  But
it turns out that it causes a problem.  If client canceled pushed
stream before push response HEADERS, stream is still in
NGHTTP2_STREAM_RESERVED state.  If push response HEADERS arrived in
this state, library happily accepts it and passed to application.

With this commit, this bug was corrected.  We now change stream state
to NGHTTP2_STREAM_CLOSING even if it was in NGHTTP2_STREAM_RESERVED
state.  We now use NGHTTP2_STREAM_FLAG_PUSH to determine whether we
have to increase/decrase stream count.

Tatsuhiro Tsujikawa b685747643 Add nghttp2_submit_shutdown_notice() to start graceful shutdown
nghttp2_submit_shutdown_notice() is used to notify the client that
graceful shutdown is started.  We expect that after this call, the
server application should send another GOAWAY using
nghttp2_submit_goaway() with appropriate last_stream_id.  In this
commit, we also added nghttp2_session_get_last_proc_stream_id(), which
can be used as last_stream_id parameter.

This commit implements graceful shutdown in nghttpx.  The integration
test for graceful shutdown is also added.

So it is better to call just item rather than data_item.  This applies
to all related functions.

Tatsuhiro Tsujikawa 8bac2087cf nghttp2_session_mem_send: Handle stream closure early
Previously session_after_frame_sent is called after we detected all
data is sent.  In nghttp2_session_mem_send, we only detect it in the
next call of the function.  It means that if a frame data bearing
END_STREAM is on flight to the peer as a result of
nghttp2_session_mem_send, peer may get that data and knows the stream
closure and issues new stream.  We may receive this new stream before
the next nghttp2_session_mem_send call, which means that we may
incorrectly assumes that peer violates maximum concurrent stream
limit.  To fix this issue, we separate session_after_frame_sent into 2
functions: session_after_frame_sent1 and session_after_frame_sent2.
session_after_frame_sent1 handles on_frame_send_callback and stream
closure and we call this early in nghttp2_session_mem_send.  This
makes number of streams are synchronized correctly with peer.

Tatsuhiro Tsujikawa 280c9dfcf3 Keep idle streams in separate list
Previously we handle idle streams as closed streams.  We only keeps
sum of closed streams and active streams under max concurrent streams
limit, idle streams gets deleted earlier than client expects.

In this change, idle streams are kept in separate list and not handled
as closed streams.  To mitigate possible attack vector to make
unlimited idle streams, we cap the number of idle streams in a half of
max concurrent streams.  This is arbitrary choice.  It may be adjusted
in the future when we have interop experience.

We make following HEADERS under priority control:

Currently, HEADERS submitted by nghttp2_submit_headers is not attached
to stream.  This is because it may be used as non-final response
header and application may submit final response using
nghttp2_submit_response without checking non-final response header
transmission.

Allowing PRIORITY frame at anytime so that PRIORITY frame to idle

open stream with new NGHTTP2_STREAM_IDLE state, which is linked in
session->closed_stream_head and is treated as if it is closed stream.
One difference is that if the stream is opened, we remove it from
linked list and change the state to the appropriate one.  To O(1)
removal from linked list, we change session->closed_stream_head to
doubly linked list.

Tatsuhiro Tsujikawa be0f6dcaaf Clear 2 types of stream deferred flag indenpendently
Previously when nghttp2_stream_resume_deferred_data() is called,
deferred flags in stream->flags are all cleared.  This is not ideal
because if application returned NGHTTP2_ERR_DEFERRED, and also that
stream is deferred by flow control, then all flags are cleared and
read callback will be invoked again.  This commit fixes this issue.
This changes error condition of nghttp2_session_resume_data().
Previously we return error if stream was deferred by flow control.
Now we don't return error in this case.  We just clear
NGHTTP2_FLAG_DEFERRED_USER and if still
NGHTTP2_FLAG_DEFERRED_FLOW_CONTROL is set, just return 0.
2014-09-26 21:32:17 +09:00
Tatsuhiro Tsujikawa a11fbf6e2f Optimize connection level remote flow control
Previously when connection level remote flow control window gets 0, we
mark the stream having DATA frame with
NGHTTP2_STREAM_FLAG_DEFERRED_FLOW_CONTROL.  When connection level
WINDOW_UPDATE is received, we checks all existing streams, including
closed ones, and call nghttp2_stream_resume_deferred_data().  The
profiler shows this is expensive.

Now we prepare dedicated priority queue for DATA frames.  And we don't
mark stream with NGHTTP2_STREAM_FLAG_DEFERRED_FLOW_CONTROL when DATA
cannot be sent solely due to connection level flow control.  Instead,
we just queue DATA item to queue.  We won't pop DATA item from queue
when connection level remote window size is 0.  This way, we avoid the
expensive operation for all streams when WINDOW_UPDATE is arrived.

Previously we missed the case where stream->data_item is not deleted

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 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.

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.

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 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.

Reworked no automatic WINDOW_UPDATE feature.  We added new API
nghttp2_session_consume() which tells the library how many bytes are
consumed by the application.  Instead of submitting WINDOW_UPDATE by
the application, the library is now responsible to submit
WINDOW_UPDATE based on consumed bytes.  This is more reliable method,
since it enables us to properly send WINDOW_UPDATE for stream and
connection individually.  The previous implementation of nghttpx had
broken connection window management.
