[issue16778] Logger.findCaller needs to be smarter

[Glynn Clements]

Glynn Clements added the comment:

Subclassing findCaller() is likely to be a bit hairy for the average user, as it deals with some fairly arcane aspects of Python internals.

As for mechanism, maybe allow functions/methods to be registered with the logging module, which would store a referenceto the function's func_code member. findCaller() would check the frame's f_code member against the set of registered functions, and continue up the stack until it found an unregistered function.
