Your Python process knows what it's got imported by looking as
sys.modules. Could your trigger prod it with some signal to tell it to
dump filenames to some well-known location? It could then check that
list for updated files.
Something like:
"""
import os
import signal
import sys
import time
def dump_modules(signum, frame):
filenames = [m.__file__ for m in sys.modules.itervalues() if
hasattr(m, '__file__')]
with open('module_filenames.txt', 'w') as f:
for filename in filenames:
filename = os.path.abspath(filename)
f.write(filename + '\n')
signal.signal(signal.SIGUSR1, dump_modules)
while True:
time.sleep(1)
"""
Yours,
Alex
