Description
Bug report
traceback.walk_stack(None) omits the calling frame, making it equivalent totraceback.walk_stack(inspect.currentframe().f_back). Given the documentation just says "If f is None, the current stack is used.", I would have expectedtraceback.walk_stack(None) to be equivalent totraceback.walk_stack(inspect.currentframe()).
Example code
The following code
importtracebackimportinspectdefabc():print(list(traceback.walk_stack(None)))print(list(traceback.walk_stack(inspect.currentframe())))print(list(traceback.walk_stack(inspect.currentframe().f_back)))abc()
has as output
[(<frame at 0x7f66ac559a40, file '/home/vincenttc/data/temp/test/test.py', line 10, code <module>>, 10)][(<frame at 0x7f66ac55fa60, file '/home/vincenttc/data/temp/test/test.py', line 7, code abc>, 7), (<frame at 0x7f66ac559a40, file '/home/vincenttc/data/temp/test/test.py', line 10, code <module>>, 10)][(<frame at 0x7f66ac559a40, file '/home/vincenttc/data/temp/test/test.py', line 10, code <module>>, 10)]Note that the frame forabc is missing in the first and last line.
