| 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. | ||
