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.
Otherwise in a weird scenario the idle timer could
be started with a more recent time then the time we
test against causing a connection to disconnect
before its idle timer was over.
- The net code no longer has a recv_queue, instead reuse same recv buffer.
- Introduce net_recv_reset() to reset the recv buffer when needed.
- Have the workers spread the load better between them by slightly
delaying their next accept lock and giving them an accept treshold
so they don't go ahead and keep accepting connections if they end
up winning the race constantly between the workers.
- The kore_worker_acceptlock_release() is no longer available.
- Prepopulate the HTTP server response header that is added to each
response in both normal HTTP and SPDY modes.
- The path and host members of http_request are now allocated on the heap.
These changes overall result better performance on a multicore machine,
especially the worker load changes shine through.
Allow Kore to use per domain CRLs when requiring client certificates.
The require_client_cert configuration option has been renamed to a more
sane client_certificates and can optionally take a second argument
which is the CRL in pem format.
You'll need a restart in case the CRLs get updated.
This commit renames certain POST centric variable and configuration
naming to the correct HTTP body stuff.
API changes include http_postbody_text() and http_postbody_bytes() to
have become http_body_text() and http_body_bytes().
The developer is still responsible for validating the method their
page handler is called with. Hopefully this becomes a configuration
option soon enough.
This function uses PQsendQueryParams() instead of the normal PQsendQuery()
allowing you to pass binary data in a cleaner fashion.
A basic call would look something like:
char *mydata = "Hello";
size_t mydata_len = strlen(mydata);
kore_pgsql_query_params(&pgsql, req,
"INSERT INTO foo VALUES($1::text)", KORE_PGSQL_FORMAT_TEXT, 1
mydata, mydata_len, KORE_PGSQL_FORMAT_TEXT);
kore_pgsql_query_params() is variadic, allowing you to pass any
count of parameters where each parameter has the following:
data pointer, data length, type of parameter.
I rather keep the old idioms instead of adding more complex things
on top of the async ones. Especially since the simple layer would
interfear with existing http state machines from your handler.
