Monitoring Function namespace

You can insert calls to the following helper function at your points of interest (such as when the server is about to perform an action as a response) to dump into a log file the entire stack trace along with values of all local variables in each frame:

import sys
import traceback

def dump_stack(file=sys.stdout):
            traceback.walk_stack(sys._getframe(1)), capture_locals=True
        ).format(), sep='\n', file=file

so that as an example:

def foo(b):
    c = b + 1

a = 1

would output something like:

  File "./", line 13, in foo
    b = 1
    c = 2

  File "./", line 16, in <module>
    __annotations__ = {}
    __builtins__ = <module 'builtins' (built-in)>
    __cached__ = None
    __doc__ = None
    __file__ = '/home/bgjPHS/./prog'
    __loader__ = <_frozen_importlib_external.SourcelessFileLoader object at 0x14ca185e5c10>
    __name__ = '__main__'
    __package__ = None
    __spec__ = None
    a = 1
    dump_stack = <function dump_stack at 0x14ca185b2040>
    foo = <function foo at 0x14ca183b7160>
    sys = <module 'sys' (built-in)>
    traceback = <module 'traceback' from '/usr/lib/python3.9/'>
