Ronald Oussoren added the comment: Interestingly enough it seems to hang while handling an import error, when I break executation and look at the stack trace I see (amongst others):
#5 0x00000001000b11f1 in import_all_from [inlined] () at /Users/ronald/Projects/python/rw/default/Python/ceval.c:4614 4614 PyErr_SetString(PyExc_ImportError, (gdb) l 4609 PyErr_Clear(); 4610 dict = _PyObject_GetAttrId(v, &PyId___dict__); 4611 if (dict == NULL) { 4612 if (!PyErr_ExceptionMatches(PyExc_AttributeError)) 4613 return -1; 4614 PyErr_SetString(PyExc_ImportError, 4615 "from-import-* object has no __dict__ and no __all__"); 4616 return -1; 4617 } 4618 all = PyMapping_Keys(dict); (gdb) This is with an optimized build, the debugger isn't as useful as I'd like and some information seem suspect (such as a frame object with an obviously invalid value for f_code. This is probably a red herring, I haven't been able to reproduce this particular problem with a debug build. In the production build I got a (non-functional) popup for entering some information, in the debug build I don't even get that and the proces hangs in CFRunLoopRunSpecific (called by Tk). And that's due to a call to "tkwait window ..." (aka the "wait_window" method from tkinter.Misc). Debugging is slightly annoying because 'pyo' from the gdb macros works, but the printing a python stack trace does not. The call is eventually traceable to calling simpledialog.askinteger in EditorWindow.tabify_region_event (through _asktabwidth) and is likely a bug where TkCocoa doesn't like callbacks into Tk from an event handler (IIRC we've had those before) A quick hack to test this theorie is to redefine tabify_region_event: def tabify_region_event(self, event): self.after(200, lambda: self._tabify_region_event(event)) def _tabify_region_event(self, event): # original method This doesn't actually help, IDLE still hangs and my theory is likely wrong. The easiest workaround is likely to give up for now and disable the ^5 and ^6 shortcuts (as well as ^3 and ^4 as those don't crash but don't do anything either, while the menu entries do work). Annoyingly other commands in the format menu work just fine (CTRL-T, CMD-], CMD-[) (all of this with the tip of the default branch and a freshly installed copy of ActiveTcl 8.5 on OSX 10.8) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16023> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
