Traceback of hanged process

[Hynek Hanke]

Hello,

please, how do I create a pythonic traceback from a python process that
hangs and is not running in an interpreter that I executed manually
or it is but doesn't react on CTRL-C etc? I'm trying to debug a server
implemented in Python, so I need some analog of 'gdb attach' for C.

Unfortunatelly, googling and reading documentation revealed nothing, so
please excuse if this question is dumb.

Thank you,
Hynek Hanke

On Windows, Pythonwin has an option "Break into running code".
Try starting the script with python -i, and send it a signal..

In python2.5, you can run a background thread that listens on a port or
unix socket, and prints a formatted version of sys._current_fr ames() to
stderr.

You can also use the signal module to similar effect. Works well in
Twisted, at least:
