Soham Sinha 3c43e00d8a Timing (#1)
* Adding timing-sensitive load test option in h2load.

* more checks added for parameters

* A worker thread can control its clients' warmup and main duration.

* Changed warmup to an enum variable.

* removed unnecessary call to ev_timer_stop

* assertion is done before starting main measurement phase

* phase variable is implemented only inside the Worker class

* enum to enum class

* else indentation corrected

* check added for timing-based test when duration CB is called explicitly

* New argument is introduced for timing-based benchmarking.

* styling corrections

* duration watcher initialization is pushed back into warmup timeout

* Warmup and Duration timer is moved to Worker instead of clients. Now both timers and phase belongs to the Workers.

* some client functions are modified to return if it's not main_duration phase. client is not destructed but sessions are terminated

* outputs are adjusted for thread.

* Needed to check if a session exist before terminating

* formatting

* more formatting

* formatting

Tatsuhiro Tsujikawa be164fc8f9 nghttpx: Set default minimum TLS version to TLSv1.2
Previously, the default minimum TLS version was TLSv1.1, but the
default cipher list didn't include any compatible ciphers with it.
This made handshake fail if TLSv1.1 was negotiated because there was
no shared ciphers.  To make the default settings consistent, the
default minimum TLS version is now TLSv1.2.

Tatsuhiro Tsujikawa 1428a5e3ae nghttpx: Verify OCSP response
At least we should make sure that the OCSP response is targeted to the
expected certificate.  This is important because we pass the file path
to the external script, and if the file is replaced because of
renewal, and nghttpx has not reloaded its configuration, the
certificate nghttpx has loaded and the one included in the file
differ.  Verifying the OCSP response detects this, and avoids to send
wrong OCSP response.

path without last "*" as prefix, and are strictly longer than wildcard
path without last "*" are matched.

Tatsuhiro Tsujikawa cc9190ab37 nghttpx: Add options for X-Forwarded-Proto header field
This commit adds 2 new options to handle X-Forwarded-Proto header
field.  The --no-add-x-forwarded-proto option makes nghttpx not to
append X-Forwarded-Proto value.  The
--no-strip-incoming-x-forwarded-proto option prevents nghttpx from
stripping the header field from client.

Previously, nghttpx always strips incoming header field, and set its
own header field.  This commit preserves this behaviour, and adds
additional knobs.

Tatsuhiro Tsujikawa 8c0b2c684a nghttpx: Add options for X-Forwarded-Proto header field
This commit adds 2 new options to handle X-Forwarded-Proto header
field.  The --add-x-forwarded-proto option makes nghttpx append
X-Forwarded-Proto value.  The --strip-incoming-x-forwarded-proto
option makes nghttpx to strip the header field from client.

Previously, nghttpx always strips incoming header field, and set its
own header field.  This commit changes this behaviour.  Now nghttpx
does not strip, and append X-Forwarded-Proto header field by default.
The X-Forwarded-For, and Forwarded header fields are also handled in
the same way.  To recover the old behaviour, use
--add-x-forwarded-proto and --strip-incoming-x-forwarded-proto
options.

Previously, nghttpx will use only one single thread inside the worker

use additional threads for accepting connections, or API request
processing, etc.

With this commit, we use the same processing model for N > 1 even if N
== 1.  To restore the original single thread execution mode,
--single-worker option is added.  If threading is disabled
--single-worker is always true.

specify minimum and maximum protocol version respectively.  Versions
between the two are enabled.  The deprecated --tls-proto-list has
empty default value, and acts like enabling only specific protocol
versions in the range for now.

Tatsuhiro Tsujikawa 56c455bca4 nghttpx: Send SIGQUIT to the original master process
Previously, after sending SIGUSR2 to the original master process, and
the new master process gets ready, user has to send SIGQUIT to the
original master process to shut it down gracefully.  With this commit,
the new master process sends SIGQUIT to the original master process
when it is ready to serve requests, eliminating for user to send
SIGQUIT manually.

This works nicely with systemd, because now you can replace nghttpx
binary with new one by "systemctl kill -s USR2 --kill-who=main
nghttpx".

Explicit io_service::stop() will prevent running streams from
finishing their task. That means if there are already reposnes
that we have called end(std::string) on them and they have not
finished sending back their data, they will be closed with a
NGHTTP2_INTERNAL_ERROR
Instead, we can stop accepting connections and destroy all
io_service::work objects to signals end of work.

nghttpx supports multiple certificates using --subcert option.
Previously, SNI hostname is used to select certificate.  With this
commit, signature algorithm presented by client is also taken into
consideration.  nghttpx now accepts certificates which share the same
hostname (CN, SAN), but have different signature algorithm (e.g.,
ECDSA+SHA256, RSA+SHA256).

Currently, this feature requires OpenSSL >= 1.0.2.  BoringSSL, and
LibreSSL do not work since they lack required APIs.

Tatsuhiro Tsujikawa 3d20c2dce6 nghttpx: Feed read event rather than calling on_read
on_read may fail, but we failed to check its return value most of the
places.  This is because failure means deletion of ClientHandler, but
because of architecture, we cannot delete it.  Feeding read event is
better since we can move call on_read from libev callback.  We can
delete ClientHandler form there.

Tatsuhiro Tsujikawa a0ce5ea9ab nghttpx: Keep reading after backend write failed
Because of bidirectional nature of TCP, we may fail write(2), but have
still pending read in TCP buffer, which may contain response body.  To
forward them, we should keep reading until get EOF from backend.

To avoid stalling HTTP/1 upload when request buffer is full, and we
have received complete response from backend, drop connection in that
case.

Tatsuhiro Tsujikawa 049e064e28 nghttpx: New error log format
To debug multi threaded configuration easier, we added current PID and
thread ID to error log.  Previously, we didn't add date and time if
log level is NOTICE.  In this change, we always write date and time
regardless of log level.

Tatsuhiro Tsujikawa fd403a85c8 nghttpx: Just return DNS_STATUS_ERROR
At the moment, we use both resolvers, and if either one is not
DNS_STATUS_IDLE, the other one is also not DNS_STATUS_IDLE.  This may
change if we are going to configure DNS so that either A or AAAA
lookup is done.  In that case, it is better to just return
DNS_STATUS_ERROR in the diff.  This is because the calling side does
not expect DNS_STATUS_IDLE in that case.

Tatsuhiro Tsujikawa 38b5cad4e3 nghttpx: Lookup backend host name dynamically
We have added "dns" parameter to backend option.  If specified, name
lookup is done dynamically.  If not, name lookup is done at start up,
or configuration reloading.  nghttpx caches DNS result including error
case in 30 seconds in this commit.  Later commit makes this
configurable.

DNS resolution is done asynchronously using c-ares library.

Normally, we don't have wait for child process to exit, since init can

not be available, and defunct processes can be piled up.  This commit
ensures that OCSP and neverbleed processes are waited for before
worker process exits.

*-bits options.  The old options are not flexible because they only
specify number of bits.  Now we can specify integer value, with
possible g, m, and k unit.  The old options are still available for
backend compatibility, but are deprecated.

std::make_shared in Xcode 7, 7.1, and 7.2 does not perform
value-initialization, and causes undefined behaviour if struct does
not have user defined default constructor.  This workaround explicitly
defines user defined default constructor, and initializes values.

Tatsuhiro Tsujikawa 5f65460944 nghttpx: Don't change pushed stream's priority
There is a discussion in httpbis mailing list which argues that
dependency tree is for client, and changing it in server side is not
what client expects.
https://lists.w3.org/Archives/Public/ietf-http-wg/2016JulSep/0416.html

Currently, we make pushed stream depend on the parent stream of
associated stream (that is main HTML in most of the cases), so that
associated stream and pushed stream become siblings.  In this case, we
also observed that these resources complete each other to get its
parent weight.  This means that the delivery of associated stream is
delayed by pushed streams.

So at this moment, it is not a good idea to change pushed stream
priority in a way we do currently.

Tatsuhiro Tsujikawa 22570b7260 nghttpx: Close fd when error occurred in reload operation
This commit also fixes the bug that old configuration is still used
for worker process.  The another bug fix is that inherited, but not
used fd is not closed in worker process.  That makes reloading next
configuration fail if it contains the address which are leaked into
worker process.

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.

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.
