Tatsuhiro Tsujikawa 6307f96fb3 nghttpx: Enable host-path backend routing in HTTP/2 backend
To achieve host-path backend routing, we changed behaviour of
--backend-http2-connections-per-worker.  It now sets the number of
HTTP/2 physical connections per pattern group if pattern is used in -b
option.

Fixes GH-292

Tatsuhiro Tsujikawa fa7069a273 nghttpx: Don't rewrite path if http2 proxy or client proxy is enabled
There are many requests which changes its meaning when we rewrite
path.  This is due to bad percent-encoding in URI; reserved characters
are just used without percent encoding.  It seems this is common in ad
services, but I suspect more to come.  For reverse proxying situation,
sane service most likely encodes URI properly, so probably this is not
an issue.

Tatsuhiro Tsujikawa 19e47a1922 nghttpx: Normalize path when setting it to Downstream 2015-07-11 16:12:35 +09:00
Tatsuhiro Tsujikawa 3119fc259c Select backend based on request host and path by extending -b option
-b option syntax is now <HOST>,<PORT>[;<PATTERN>[:...]].  The optional
<PATTERN>s specify the request host and path it is used for.  The
<PATTERN> can contain path, host + path or host.  The matching rule is
closely designed to ServeMux in Go programming language.

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.

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.

Tatsuhiro Tsujikawa dce20c3e6a nghttpx: Check HTTP/2 downstream connection after certain idle time
Previously when requests are issued to HTTP/2 downstream connection,
but it turns out that connection is down, handlers of those requests
are deleted.  In some situations, we only know connection is down when
we write something to network, so we'd like to handle this kind of
situation in more robust manner.  In this change, certain seconds
passed after last network activity, we first issue PING frame to
downstream connection before issuing new HTTP request.  If writing
PING frame is failed, it means connection was lost.  In this case,
instead of deleting handler, pending requests are migrated to new
HTTP2/ downstream connection, so that it can continue without
affecting upstream connection.

Tatsuhiro Tsujikawa 9614611969 nghttpx: Limit # of downstream connections per host when h2 proxy is used
This commit limits the number of concurrent HTTP/1 downstream
connections to same host.  By defualt, it is limited to 8 connections.
--backend-connections-per-frontend option was replaced with
--backend-http1-connections-per-host, which changes the maximum number
of connections per host.  This limitation only kicks in when h2 proxy
is used (-s option).

Tatsuhiro Tsujikawa 154876a17b nghttpx: Apply TLS record length limit to DATA frame payload
This is not obvious but it makes intermediaries flush and forward DATA
frame boundary without excessive buffering.  Since we have different
TCP connections frontend and backend, this may not work.  This is
still experimental.

HTTP/2 and SPDY upstream connections.

Tatsuhiro Tsujikawa b305495a75 nghttpx: Reset both timeouts when either read or write succeeds
Previously read and write timeouts work independently.  When we are
writing response to the client, read timeout still ticks (e.g., HTTP/2
or tunneled HTTPS connection).  So read timeout may occur during long
download.  This commit fixes this issue.  This commit only fixes the
upstream part.  We need similar fix for the downstream.

Tatsuhiro Tsujikawa 0209b7c083 nghttpx: Fix location rewrite is failed because request headers are empty
Previously we empties request headers after they are sent to
downstream in order to free memory.  But it turns out that we use
request headers when rewriting location header response field.  Also
user reported that request headers are useful to add new features.
This commits defers the deletion of request headers to the point when
response headers are deleted (which is after response headers are sent
to upstream client).

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 d5dcbf6f3b nghttpx: Fix possible flow control issue
Previously we only update consumed flow control window when number of

nghttp2 library the consumed bytes even if number of bytes read > 0.
This change also uses newly added spdylay_session_consume() API, so we
require spdylay >= 1.3.0.
