pwnlib.atexit — Replacement for atexit¶
Replacement for the Python standard library’s atexit.py.
This module also fixes a the issue that exceptions raised by an exit handler is printed twice when the standard atexit is used.
- pwnlib.atexit.register(func, *args, **kwargs)¶
Registers a function to be called on program termination. The function will be called with positional arguments args and keyword arguments kwargs, i.e. func(*args, **kwargs). The current context is recorded and will be the one used when the handler is run.
E.g. to suppress logging output from an exit-handler one could write:
with context.local(log_level = 'error'): atexit.register(handler)
An identifier is returned which can be used to unregister the exit-handler.
This function can be used as a decorator:
@atexit.register def handler(): ...
Notice however that this will bind handler to the identifier and not the actual exit-handler. The exit-handler can then be unregistered with:
This function is thread safe.
Remove the exit-handler identified by ident from the list of registered handlers. If ident isn’t registered this is a no-op.
