> Currently, if a task fails it is retried over and over again which basically is kind of an endless loop.
> However, if between two retries nothing has changed, it is most likely that a retry is failing again. We have some basic code for bundle handling, but this is a) tied to bundles, b) not reusable, and c) not working perfectly.
> Instead we should come up with a generic mechanism for retries - a task should signal that it want's to be retried. In addition we need a notification mechanism which notifies the installer to retry something, e.g. a service listening for bundle events would notify the installer each time a bundle event has occurred etc.
