Bug 526010 - Very long check when deleting thousands of sub-packages When deleting a package with a few thousand sub-packages, a check during removal takes up to several minutes. This cannot be cancelled by canceling the delete operation. This check is done in DeleteModifications.postProcess. The method iterates over all packages that are to be removed. For each of those packages, the method will retrieve all sub-packages. For each of those sub-packages, it checks whether that sub-package is to be removed. This last check is on an array container. In total, this results in cubic complexity. With this change the algorithm which checks whether it can remove a package completely has linear complexity, instead of quadratic. The total complexity for deleting the packages is therefore quadratic, instead of cubic. The check for a few thousand sub-packages then takes a few seconds instead of minutes.
