Tatsuhiro Tsujikawa 494775a25d nghttpx: Rename SignalServer with WorkerProcess 2016-07-31 16:16:23 +09:00
Tatsuhiro Tsujikawa 1214f9e23b nghttpx: Reload configuration with SIGHUP
This commit implements configuration reloading with SIGHUP.
There are rough edges left:

* Rename SignalServer with more meaningful name, say, WorkerProcess.
* We should introduce global configuration object which is not
  affected by configuration reloading.  It should hold cmdcfgs, argc,
  argv, and last worker PID.
* We should close the listener file descriptor when some operation was
  failed after that.

Tatsuhiro Tsujikawa 3c1c2c4aad nghttp: Allow multiple -p option
The N-th -p options sets N-th URI's weight.  If the number of -p is
less than the number of URIs, the last -p value is repeated.  If no -p
is set, use default weight, 16.

Tatsuhiro Tsujikawa 33153010c5 nghttpx: Retry memcached connection
Previously, we didn't retry request on connection failure.  Sometimes
we hit the edge case where connection is about to lost just when we
write request.  To avoid this situation, we now retry request to
failed attempt.  We also add ConnectBlocker to MemcachedConnection not
to attempt to connect to memcached if connection could not be made
previously.

Tatsuhiro Tsujikawa 2a4733857f nghttpx: Reduce TTFB with large number of incoming connections
To reduce TTFB with large number of incoming connections, we now
intentionally accept one connection at a time, so that it does not
delay the TTFB of the existing connection.  This is significant
especially for TLS connections.

Tatsuhiro Tsujikawa cbced219ec nghttpx: Rewrite read timer handling
For HTTP/2, read timer starts when there is no downstream, and timer
stops when there is at least one downstream.  For HTTP/1, read timer
starts when request handling finished, and timer stops when request
handling starts.

h2load has supported uploading a file quite a while, but it turns out
that it worked with HTTP/2 and SPDY only.  HTTP/1 with upload did not
work.  This commit fixes this bug, and implement HTTP/1 upload.  Due
to architectural limitation of h2load, when -d option is used, the
number of in-flight pipe-lined requests is set to 1.
