Tatsuhiro Tsujikawa cf1cfca51f shrpx: Fix not send RST_STREAM when downstream gets valid EOF 2013-03-01 00:05:57 +09:00
Tatsuhiro Tsujikawa da36fc3953 shrpx: Fix WINDOW_UPDATE may block until SpdyUpstream::send()
spdy_data_read_callback in SpdyDownstreamConnection calls
SpdyUpstream::resume_read() which submits WINDOW_UPDATE, but after
that they are not call SpdyUpstream::send(). This means that if no
pending outgoing data in upstream, then WINDOW_UPDATE is blocked until
SpdyUpstream::send() from somewhere. This change adds
SpdyUpstream::send() to resume_read() so that WINDOW_UPDATE is not
blocked.

Tatsuhiro Tsujikawa 7b3f57cef8 shrpx: Fix blocking upstream RST_STREAM and propagate REFUSED_STREAM
This change fixes upstream RST_STREAM is blocked until
SpdyUpstream::send() is called. Now downstream REFUSED_STREAM is
propagated to upstream client so that client can reset request.  The
RST_STREAM error code when downstream went wrong is changed from
CANCEL to INTERNAL_ERROR.

Tatsuhiro Tsujikawa b43b31c362 shrpx: Remove x-forwarded-spdy header field 2013-02-09 17:21:46 +09:00
Tatsuhiro Tsujikawa 9ba19df813 shrpx: Add --spdy-bridge option
With --spdy-bridge option, it listens SPDY/HTTPS connections from
front end and forwards them to the backend in SPDY. The usage will be
written later. This change fixes the crash when more than 2
outstanding SpdyDownstreamConnection objects are added to SpdySession
and establishing connection to SPDY backend is failed.

Tatsuhiro Tsujikawa 29bec93eb9 shrpx: Don't run expensive INFO log code
INFO log and its surrounding code are now guarded by
LOG_ENABLED(SEVERITY) macro so that they don't run if log level
threshold is higher. This increases performance because log formatting
is somewhat expensive.

Tatsuhiro Tsujikawa c48fb56d3f shrpx: Add content-length header field to SPDY upstream error page
create_error_html() is rewritten without std::stringstream.

Tatsuhiro Tsujikawa c45fa16f94 shrpx: Add --no-via option
If --no-via option is given, shrpx does not append to Via header
field. If Via header field is received, it is left unaltered.

Tatsuhiro Tsujikawa bbf6c18575 shrpx: Log format change
Added macros which log messages from the following components are
prefixed with their component name + object pointer address:

ListenHandler: LISTEN
ThreadEventReceiver: THREAD_RECV
Upstream: UPSTREAM
Downstream: DOWNSTREAM
DownstreamConnection: DCONN
SpdySession: DSPDY

Tatsuhiro Tsujikawa 8a5db1751e shrpx: Check the length of output buffer in write callback
Possibly because of deferred callback, we may get this callback when
the output buffer is not empty.

Tatsuhiro Tsujikawa fa552c6788 shrpx: Share SPDY session among multiple frontend connections per thread
In client mode, now SPDY connection to the backend server is
established per thread.  The frontend connections which belong to the
same thread share the SPDY connection.

Tatsuhiro Tsujikawa 026f4ca3a2 Add --client-mode option
With --client-mode option, shrpx now accepts unencrypted HTTP
connections and communicates with backend server in SPDY.  In short,
this is the "reversed" operation mode against normal mode.  This may
be useful for testing purpose because it can sit between HTTP client
and shrpx "normal" mode.

Tatsuhiro Tsujikawa 7f481e42b0 shrpx: Add more spdylay callback
The on_ctrl_not_send_callback, on_ctrl_recv_parse_error_callback and
on_unknown_ctrl_recv_callback were added. The latter 2 callbacks are
purely debugging purpose.  In on_ctrl_not_send_callback, If sending
SYN_REPLY failed, issue RST_STREAM to avoid a stream hanging around.

Tatsuhiro Tsujikawa b0fcd68783 Move spdycat, spdyd and shrpx from examples to src
To distinguish the to-be-installed programs and non-installable
example source code, the former programs, spdycat, spdydyd and shrpx,
were moved to src directory. spdynative was removed from Makefile
because it does not appeal to any users much.
