Graham Dumpleton commented on MODPYTHON-198:
--------------------------------------------
Dan provides confirmation that something like:
>>> def foo(a,b):
d = 5
def __auth__(req):
return True
e = d + 5
>>> fc = foo.func_code
>>> import new
>>> func_globals = globals()
>>> for i, var_name in enumerate(fc.co_varnames):
if var_name == '__auth__':
__auth__ = fc.co_consts[i-fc.co_argcount+1]
if hasattr(__auth__, 'co_name'):
__auth__ = new.function(__auth__, func_globals)
found_auth = 1
break
>>> __auth__
<function __auth__ at 0x01159830>
would appear to work.
In practice need to support old and new versions of Python, so will need to
check both co_names and co_varnames.
