Tatsuhiro Tsujikawa 2af57c3cfc nghttpx: Add --single-worker option
Previously, nghttpx will use only one single thread inside the worker
process if --workers=1 (this is default).  If --workers=N, N > 1, we
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.

Tatsuhiro Tsujikawa 450ffaa6f0 nghttpx: Add configrevision API endpoint
This commit adds configuration revision, which is considered opaque
string, and changes after reloading configuration with SIGHUP.  This
revision is returned as a response to configrevision API endpoint.
This allows external application to know whether nghttpx has finished
reloading new configuration or not.  Note that this revision does not
change on backendconfig API calls.

Tatsuhiro Tsujikawa a7c780a732 nghttpx: Redirect to HTTPS URI with redirect-if-not-tls param
This commit removes frontend-tls parameter, and adds
redirect-if-not-tls parameter parameter to --backend option.  nghttpx
now responds to the request with 308 status code to redirect the
request to https URI if frontend connection is not TLS encrypted, and
redirect-if-no-tls parameter is used in --backend option.  The port
number in Location header field is 443 by default (thus omitted), but
it can be configurable using --redirect-https-port option.

unlock all the features nghttpx offers.  OpenSSL's TLSv1.3 support is
still WIP at the time of writing.

Tatsuhiro Tsujikawa b36e53cccd nghttpx: Specify TLS protocol by version range
This commit deprecates --tls-proto-list option, and adds 2 new
options: --tls-min-proto-version and --tls-max-proto-version to
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 001d45efad Merge branch 'nghttpx-graceful-sigusr2' 2017-02-12 23:52:03 +09:00
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".

Amir Pakdel 1c31213aef More graceful stop of nghttp2::asio_http2::server::http2
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.

Tatsuhiro Tsujikawa 68a724cf7b nghttpx: Select certificate by client's supported signature algo
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.

Plain write(2) is OK, but SSL_write requires same arguments on retry.
It would be better to avoid calling them again.

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 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

case in 30 seconds in this commit.  Later commit makes this
configurable.

DNS resolution is done asynchronously using c-ares library.

and --backend-http2-connection-window-size option to replace existing
*-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.

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.

* We should introduce global configuration object which is not

  argv, and last worker PID.
* We should close the listener file descriptor when some operation was
  failed after that.
