[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] Remove many unnecessary uses of keyword arguments, to reduce complexity.
# HG changeset patch
# User emellor@xxxxxxxxxxxxxxxxxxxxxx
# Node ID f72da879941828f54a5c592500b1c78938311979
# Parent e336e186e5f96a0e93f842ca3a2e39601c2a0193
Remove many unnecessary uses of keyword arguments, to reduce complexity.
Have the self parameter to all the methods be an XsHandle, not a PyObject, to
avoid casting.
