Unable to pickle classes used in the InteractiveConsole. The code attached works in python 2.5 and fails on python 3.1.2. |

Yes, the problem is observed in py3k. Pickle module when used via Interactive console is trying to import the class as __console__.ClassName and it is failing to see the __console__ module. _pickle.PicklingError: Can't pickle <class '__console__.Example'>: import of module '__console__' failed |

One easy fix for this would be to make InteractiveConsole use the string "__main__" instead of "__console__". But other than that, I don't think we can fix this within pickle. |

Bug stills on branch http://svn.python.org/projects/python/branches/py3k branch http://svn.python.org/projects/python/branches/release27-maint is OK doing some gdb on 3.2, I have discovered that the problem occurs when trying to dump global Example from module __console__ on py3k/Modules/_pickle.c:save_global:2536 Python 2.7 never calls save_global (why?) in annex: an update test |

Well, this is a pickle problem or a Interactive console problem? on python 2.7 does not save a type "type" (like Example class is) 2: type->tp_name = 0x58a87c "instance" 2: type->tp_name = 0x590391 "dict" 2: type->tp_name = 0x5943b6 "str" 2: type->tp_name = 0x5943b6 "str" on python 3.2 does and when saving a type, it tries to save a global. |
