Hi,
I wonder, if I have this example program:
https://twistedmatrix.com/documents/current/web/howto/using-twistedweb.html#site-objects
how do I initialize an external resource (like a dictionary, which is
fetched from a database) with asynchronous twisted tools, but before
the HTTP server starts listening on its port?
The goal here is that the HTTP server shouldn't start until it can
fetch the desired data. Of course I can do this in a synchronous way,
but it feels so unnatural and bad practice to fetch the same stuff
synchronously on initialization and asynchronously when the
program/reactor is running (often with different libraries).
Thanks,
