In the test suite for one of my packages, I've used something like gen.gi_frame.f_code.co_name to help make human-readable assertions about when certain generators are run deep inside the application. This was possible because Python 2.4 guaranteed that gi_frame was always a frame instance, even after the generator exhausted itself. In Python 2.5, however, gi_frame is None when the generator has run till exhaustion, meaning that I can't always get to f_code.co_name. I'd like to add a gi_code attribute to generators that would allow users to access the code object behind the generator, even when gi_frame is None. This attribute would be read-only and would follow this rule: >>> def f(): ... yield 5 ... >>> g = f() >>> g.gi_code is f.func_code True >>> The attached patch (against r45570) implements the proposed attribute (in Include/genobject.h and Objects/genobject.c) and adds test cases to Lib/test/test_generators.py for this attribute. |

Logged In: YES user_id=1344176 In addition to updating the main patch to r46040, I've included a diff against Misc/NEWS to make mention of the gi_code attribute. Any thoughts on getting this into 2.5a3? |

Guido, do you have an opinion? Seems like a nonproblematic and probably useful change for 2.6. |

I noticed some whitespace issues in the patch, but apart from that I have no objection. (Not any particular enthusiasm, I have to admit -- I don't quite get the use case, but as Georg remarks, it seems harmless.) |

Reformatted the patch to use tabs and committed as r60324. |
