[issue27910] Doc/library/traceback.rst — references to tuples should be replaced with new FrameSummary object
by Tomas Orsava 02 Aug '18

02 Aug '18

New submission from Tomas Orsava: In the documentation for the `traceback` module, the definitions of functions `extract_tb` [0], `format_list` [1] and classmethod `from_list` [2] mention the old style (4-)tuples that these functions used to return or accept. Since Python 3.5, however, they return or accept a FrameSummary object instead of the 4-tuple, or a StackSummary object instead of a list of 4-tuples. I'm including a patch that fixes these definitions to make them reflect the new reality.

[issue30984] traceback.print_exc return value documentation
by Jelle Zijlstra 02 Aug '18

02 Aug '18

New submission from Jelle Zijlstra: The documentation for traceback.format_tb says "Return a list of “pre-processed” stack trace entries extracted from the traceback object tb. It is useful for alternate formatting of stack traces. The optional limit argument has the same meaning as for print_tb(). A “pre-processed” stack trace entry is a 4-tuple (filename, line number, function name, text) representing the information that is usually printed for a stack trace." However, as of 3.5 it actually returns a StackSummary object, which is a subclass of list and contains FrameSummary objects. FrameSummary objects are not tuples. The documentation is accurate for 3.4 and earlier. I'm surprised this change was made because it seems like a compatibility break, but it's too late to do something about that now. The documentation should be changed to correct the return value and add a "versionchanged: 3.5" note. ---------- assignee: docs@python components: Documentation messages: 298807 nosy: Jelle Zijlstra, docs@python priority: normal severity: normal status: open title: traceback.print_exc return value documentation versions: Python 3.6, Python 3.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue30984> _______________________________________
