Overview
Refactors internal APIv4 code to more reliably handle pre-save processing.
Technical Details
The
PreSaveSubscriber
was added in the early days of APIv4 to tweak inputs before saving a record, but it was unreliable because:Create
andUpdate
but notSave
actionsMeanwhile, a new pattern of overriding the create/save/update actions and sharing a trait has become more common and while a bit more cumbersome to implement, it does not have the above limitations.
This removes all inheritors of
PreSaveSubscriber
but keeps it around with a deprecation warning in case any extension in the Universe happens to rely on it.
