As mentioned offline:
update_filteris a bit unsatisfactory to me. E.g. it leads to irritation with users (see #1595) and makes typing hard (see #1920)What this PR does is:
BaseFilter.__call__an abstract method and implement two subclasses:MessageFilterandUpdateFilter, each of which will take care of passing the right object tofilter()update_filter, make the filters inherit from those.BaseFiltertoMessage/UpdateFilterin order to make typing even more clear. This makes it breaking, butBaseFiltertoMessageHandleris not too bad. Leavingupdate_filter = Truewon't even hurt …Offline I also mentioned dropping
data_filter, but that was nonsense, as we need that for the short circuit logic of the filtersCloses #1595 and #1596
