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) |
