From 9943e0ec38786125ce1bbaf82ba6c3cadb976ba6 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Mon, 30 Apr 2012 12:00:23 +0100 Subject: tracetool: avoid pkgutil.iter_modules() Python 2.7 function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The pkgutil.iter_modules() function provides a way to enumerate child modules. Unfortunately it's missing in Python <2.7 so we must implement similar behavior ourselves.
