commit 0e47639a44e1630250ea10643f5a440281edfdce
Author: Andy Grover <agrover@redhat.com>
Date: Wed Oct 17 12:55:25 2012 -0700
python-lvm: Implement proper refcounting for parent objects
Our object nesting:
lib -> VG -> LV -> lvseg
-> PV -> pvseg
Implement refcounting and checks to ensure parent objects are not
dealloced before their children. Also ensure calls to self or child's
methods are handled cleanly for objects that have been closed or removed.
Ensure all functions that are object methods have a first parameter named
'self', for consistency
Rename local vars that reference a Python object to '*obj', in order to
differentiate from liblvm handles
Fix a misspelled pv method name

commit 84a4d4b970bb9aaf540ad5fa82276b1caf5aa9bd
Author: Andy Grover <agrover@redhat.com>
Date: Mon Oct 15 13:26:01 2012 -0700
python-lvm: Remove liblvm object
Instead of requiring users to create a liblvm object, and then calling
methods on it, the module acquires a liblvm handle as part of
initialization. This makes it impossible to instantiate a liblvm object
with a different systemdir, but there is an alternate envvar method for
that obscure use case.
