Hi, the most updated stuff is only available in the sources:
https://github.com/unbit/uwsgi/blob/master/plugins/python/uwsgi_pymodule.c#L3511

the functions should be easy to follow even for a non-C programmer.

Yes, the cache_server should be cache_name.

The inc/dec/mul/... functions are for "atomic" math operations (a lock
will allow inter-process safety)
