So I would really like to accomplish the following:
run a program normally and keep track of all the imports that were
actually done.
I studied the PEP 302, but I'm still a bit confused about how to do it.
I thought that instead of implementing everything I could just record
the request
and then delegate to the "imp" module, so I did this:
class MyLoader(object):
"""
Loader object
"""
def __init__(self):
self.loaded = set()
def find_module(self, module_name, package=None):
print("requesting %s" % module_name)
self.loaded.add(module_name)
return self
def load_module(self, fullname):
#XXX: the find_module is actually doing nothing, since
# everything is delegated to the "imp" module
fp, pathname, stuff = imp.find_module(fullname)
imp.load_module(fullname, fp, pathname, stuff)
myl = MyLoader()
sys.meta_path.append(myl)
try:
import random
import os
print(random.random())
Which doesn't work, and very strangely it doesn't even look deterministic!
Sometimes it stops at first import sometimes it's able to do a few of them.
How can that be?
And how could I do solve my problem?
