From 23b093ee087e99049585487f59e262a0e0662b6e Mon Sep 17 00:00:00 2001 From: Brandon Casey Date: Wed, 9 Jun 2010 19:24:54 -0500 Subject: Remove python 2.5'isms The following python 2.5 features were worked around: * the sha module is used as a fallback when the hashlib module is not available * the 'any' built-in method was replaced with a 'for' loop * a conditional expression was replaced with an 'if' statement * the subprocess.check_call method was replaced by a call to subprocess.Popen followed by a call to subprocess.wait with a check of its return status These changes allow the python infrastructure to be used with python 2.4 which is distributed with RedHat's RHEL 5, for example. t5800 was updated to check for python >= 2.4 to reflect these changes.
