New submission from Adam Bielański:
Issue: cgitb text formatter outputs all members of exception object, using
standard dir() to get their names.
My patch changes its behaviour to skip fields which are callable, since
printing them only clutters the output but is rarely helpful.
HTML formatter skips members starting with underscore (_), which is slightly
different behaviour and I can alter my patch to make both formatters behave in
the same way, should the need be. Both can skip members starting with
underscore, callables, or callables and values starting with underscore - any
option will be better than printing them all.
Current change alters output for exception value Exception("123412312") from:
<type 'exceptions.Exception'>: 123412312
__class__ = <type 'exceptions.Exception'>
__delattr__ = <method-wrapper '__delattr__' of exceptions.Exception object>
__dict__ = {}
__doc__ = 'Common base class for all non-exit exceptions.'
__format__ = <built-in method __format__ of exceptions.Exception object>
__getattribute__ = <method-wrapper '__getattribute__' of
exceptions.Exception object>
__getitem__ = <method-wrapper '__getitem__' of exceptions.Exception object>
__getslice__ = <method-wrapper '__getslice__' of exceptions.Exception
object>
__hash__ = <method-wrapper '__hash__' of exceptions.Exception object>
__init__ = <method-wrapper '__init__' of exceptions.Exception object>
__new__ = <built-in method __new__ of type object>
__reduce__ = <built-in method __reduce__ of exceptions.Exception object>
__reduce_ex__ = <built-in method __reduce_ex__ of exceptions.Exception
object>
__repr__ = <method-wrapper '__repr__' of exceptions.Exception object>
__setattr__ = <method-wrapper '__setattr__' of exceptions.Exception object>
__setstate__ = <built-in method __setstate__ of exceptions.Exception object>
__sizeof__ = <built-in method __sizeof__ of exceptions.Exception object>

args = ('123412312',)
