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.) �����c�����������������C���s���|�j����}t|��j|d<�|S�)aL��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__�copy�typer���)�self�state��r ����9/usr/lib/python3.9/site-packages/cloudinit/persistence.py�__getstate__���s���� z!CloudInitPickleMixin.__getstate__N)r����returnc�����������������C���s&���|��dd�}|�j�|��|��|��dS�)aE��Restore 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). See https://docs.python.org/3/library/pickle.html#object.__setstate__ for further background. r���r���N)�popr����update� _unpickle)r���r����versionr ���r ���r ����__setstate__'���s���� z!CloudInitPickleMixin.__setstate__)�ci_pkl_versionr���c�����������������C���s���dS�)a>��Perform any deserialization fixes required. 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.
