rsync: filter() method + delete=True leads to unexpected results

I'm using an RSync subclass that implements filter() to ignore some parts of a large tree, specifically things where the remote side has a local version like a virtualenv that should not be touched at all, however, it currently always deletes the remote version ...

I'd be happy to improve the code but need to know whether in general filter()=False + delete=True would expect a filtered item to be removed or left alone on the remote side ... my personal favorite would be to have it ignore the deletions on the remote side and eventually adding a delete_filtered option. This would be in sync with the way regular rsync works.

Non vengono indicati file o test. Inizia individuando la gestione di RSync filter() e delete=True, quindi esamina i test di sincronizzazione esistenti e il comportamento documentato di rsync standard. Il lavoro è completato quando il trattamento previsto degli elementi remoti filtrati è stato deciso e coperto da test di regressione.
