Work around hotshot IndexError: pop from empty list in python < 2.7 #371

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. run --with-profile using a version of Python < 2.7
2. wait until stats are processed

What is the expected output? What do you see instead?

It should process the stats but instead I get this Traceback:

Traceback (most recent call last):

IndexError: pop from empty list

Note that this is a Python bug that is **fixed** in Python 2.7, see 
http://bugs.python.org/issue1019882

The bug suggests working around the issue by calling .run() instead of .start() 
and .stop() so perhaps Nose can do that?  Not sure if that's feasible.

Please use labels and text to provide additional information.

In this case Nose was executed as manage.py test using DjangoNose
