This class implements ``__getstate__`` and ``__setstate__`` to provide lightweight versioning of the pickles that are generated for classes which use it. Versioning is done at the class level. The current version of a class's pickle should be set in the class variable ``_ci_pkl_version``, as an int. If not overridden, it will default to 0. On unpickle, the object's state will be restored and then ``self._unpickle`` is called with the version of the stored pickle as the only argument: this is where classes should implement any deserialization fixes they require. (If the stored pickle has no version, 0 is passed.) cjURR5n[U5RUS'U$)a$Persist instance state, adding a pickle version attribute. This adds a ``_ci_pkl_version`` attribute to ``self.__dict__`` and returns that for serialisation. The attribute is stripped out in ``__setstate__`` on unpickle. The value of ``_ci_pkl_version`` is ``type(self)._ci_pkl_version``. _ci_pkl_version)__dict__copytyper)selfstates 7/usr/lib/python3/dist-packages/cloudinit/persistence.py __getstate__!CloudInitPickleMixin.__getstate__s0 ""$#':#=#=  r returnNcURSS5nURRU5 URU5 g)aRestore instance state and handle missing attributes on upgrade. This will be called when an instance of this class is unpickled; the previous instance's ``__dict__`` is passed as ``state``. This method removes the pickle version from the stored state, restores the remaining state into the current instance, and then calls ``self._unpickle`` with the version (or 0, if no version is found in the stored state).

By default, this does nothing. Classes using this mixin should override this method if they have fixes they need to apply. ``ci_pkl_version`` will be the version stored in the pickle for this object, or 0 if no version is present.
