[Layer dependencies] Emit QgsVectorLayer::dataChanged on commitChanges

Open Djedouas opened this issue 5 months ago • 5 comments

Description

Fixes #57784 where even if the layer is checked as a dependency layer, there is no reloading of data when the layer is saved.

With this change, the dataChanged signal is emitted on commitChanges, so that when a feature is externally modified on save (database trigger for example) we have index and cache reconstruction.

This change is kind of following this particular comment/discussion https://github.com/qgis/QGIS/pull/41463#issuecomment-777094703

See the tests explaining the multiple emissions of dataChanged.
