Before kore needed to be built with NOTLS=1 to be able to do non TLS
connections. This has been like this for years.
It is time to allow non TLS listeners without having to rebuild Kore.
This commit changes your configuration format and will break existing
applications their config.
Configurations now get listener {} contexts:
listen default {
bind 127.0.0.1 8888
}
The above will create a listener on 127.0.0.1, port 8888 that will serve
TLS (still the default).
If you want to turn off TLS on that listener, specify "tls no" in that
context.
Domains now need to be attached to a listener:
Eg:
domain * {
attach default
}
For the Python API this kills kore.bind(), and kore.bind_unix(). They are
replaced with:
kore.listen("name", ip=None, port=None, path=None, tls=True).
Change the callback prototypes to:
void callback(struct kore_msg *msg, const void *data);
This allows the callbacks to receive the full kore_msg data structure
as sent over the wire (including length and id). Useful for future
additions to the kore_msg structure (such as worker origin).
Several other improvements:
* Accesslog now uses the msg framework as well.
* Websocket WEBSOCKET_BROADCAST_GLOBAL now works.
Small websocket improvement in this commit:
* Build the frame to be sent only once when broadcasting
instead of per connection we are broadcasting towards.
Add configuration setting tls_version to specify if you
either want TLSv1.2 or TLSv1.0 or both.
The configuration options ssl_cipher and ssl_dhparam
have changed name to tls_cipher and tls_dhparam. There is
no fallback so you might have to update your configs.
Introduces a few new api functions:
- kore_websocket_handshake(struct http_request *):
Performs the handshake on an HTTP request (coming from page handler)
- kore_websocket_send(struct connection *, u_int8_t, void *, size_t):
Sends data to a websocket connection.
- kore_websocket_broadcast(struct connection *, u_int8_t, void *, size_t, int):
Broadcast the given websocket op and data to all connected
websocket clients on the worker. Note that as of right now
the WEBSOCKET_BROADCAST_GLOBAL scope option does not work
yet and messages broadcasted will be restricted to workers
only.
- kore_worker_websocket_broadcast(struct connection *, void *, void *):
Backend function used by kore_websocket_broadcast().
Could prove useful for developers to have access to.
A simple example is given under examples/websocket.
Known issues:
Kore does not support PING or CONT frames just yet.
