[DataOffer] Avoid calls on null DataSource (!85) · Merge requests · Plasma / KWayland Server

David Edmundson requested to merge work/data_source into master Sep 18, 2020

A DataOffer can slightly outlive a DataSource; a client will still be told it's deleted but could call a method in a race.

DataOfferInterface correctly checks for source being still valid, but nothing updates it when it gets deleted.

BUG: 396308
