Signal-triggered process reloader

Project description

Pyexec allows to setup signal handler, which will reload current process. This functionality might be used to restart application, e.g. when the code’s been changed, by sending an appropriate signal to the python process.

Exemplary usage:

import os
import pyexec
import signal
import sys

def handler():
    sys.stderr.write('Reloading process!\n')
    return sys.argv + ['reloaded']

sys.stderr.write('[%d]: argv: %r\n' % (os.getpid(), sys.argv))
pyexec.install(signal.SIGUSR1, handler)
signal.pause()

The output from the python process after sending the USR1 signal twice:

$ python example.py
[20785]: argv: ['example.py']
Reloading process!
[20785]: argv: ['example.py', 'reloaded']
Reloading process!
[20785]: argv: ['example.py', 'reloaded', 'reloaded']
