Superseeded by #1342. We choose to go a simpler route and always deepcopy the data. Thanks a lot for both finding the issue and taking the time to make the PR :D |

As reported in #1297, the use of shallow copies in
PicklePersistenceleads to data not being persisted. Same holds forDictPersistenceA fix would be the use ofcopy.deepcopy, which however may become time consuming for large data sets.I therefore implemented an additional argument
on_updateforPickle/DictPersistencethat let's you choose wether to check for updates before dumping or not.If
on_update = False, checking is obmitted and one can skip time consuming deepcopies (i.e. just pass the actual data). Ifon_update = True, deepcopies are used.
