<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The version_str should probably be a static to the AsteriskVersion class:
1. Once it is set within a process, we wouldn't expect the Asterisk version to change
2. Every subsequent creation of an AsteriskVersion object could check to see if the version number was assigned - if so, it wouldn't need to spawn a process
Otherwise, the asterisk wrapper class will be spawning a lot of children processes to wait on.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think it is going to be more complicated adding the version string to a static variable right now, since we have object compare functions. Or maybe my brains is not working today.
Either way, do you have an example of how you would like to see it?
FWIW: We do a good job of passing the ast_version object round within runtests.py</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Static in python would be a variable declared outside of the __init__ method but within the class. Initially, set it to blank.
version_str = ""
def __init__(self, [other params]):
if (AsteriskVersion.version_str != "")
""" do a popen, set it, etc.
else:
""" Do your version comparisons """
version_str would no longer be a member variable, but rather static to the class, i.e., don't refer to it as "self.version_str". This would let external entities not have to pass around the object once they've calculated the version once, and you'd only have to calculate the version once within a process.</pre>
