caches: call 'repo.updatecache()' in 'repo.destroyed()' Regenerating the cache after a 'strip' or a 'rollback' is useful. So we call the generic cache warming function as other caches than just branchmap will be updated there in the future. To do so, we have to make 'repo.updatecache()' able to take no arguments. In such cases, we reload all caches.
