I've got two tasks, `do_A` and `do_B` (they are really IMAGE_CMDs if it's important). Now I want to introduce a third task, `do_check_A_and_B`, that will test that `do_A` and `do_B` have produced a correct result. If the test fails, I want to invalidate results of A and B, so that they re-run next time I run `bitbake some-image`. Is it possible? I've seen some "invalidate_task" functions in bb.siggen and in bb.runqueue, but I'm not sure about how to use them in a recipe/bbclass.
That would be a gross hack that goes against bitbake philosophy - which is that once a task completes successfully, you never need to re-run it again, unless the task content (or its dependencies) changes.
What are you doing in do_A and do_B, and why the outcome can vary without the tasks themselves changing? Are you fetching something from the network?
