21 | This module implements an xmlrpc server for BitBake. | ||
22 | |||
23 | Use this by deriving a class from BitBakeXMLRPCServer and then adding | ||
24 | methods which you want to "export" via XMLRPC. If the methods have the | ||
25 | prefix xmlrpc_, then registering those function will happen automatically, | ||
26 | if not, you need to call register_function. | ||
27 | |||
28 | Use register_idle_function() to add a function which the xmlrpc server | ||
29 | calls from within server_forever when no requests are pending. Make sure | ||
30 | that those functions are non-blocking or else you will introduce latency | ||
31 | in the server's main loop. | ||
