Debugging manhole for python applications
Manhole is in-process service that will accept unix domain socket connections and present the stacktraces for all threads and an interactive prompt. It can either work as a python daemon thread waiting for connections at all times or a signal handler (stopping your application and waiting for a connection).
Access to the socket is restricted to the application's effective user id or root.
This is just like Twisted's manhole. It's simpler (no dependencies), it only runs on Unix domain sockets (in contrast to Twisted's manhole which can run on telnet or ssh) and it integrates well with various types of applications.
Features:
* Uses unix domain sockets, only root or same effective user can connect. * Can run the connection in a thread or in a signal handler. * Compatible with apps that fork, reinstalls the Manhole thread after fork. * Compatible with gevent and eventlet with some limitations * The thread is compatible with apps that use signalfd
