details.\n\nFor taskflow exception, I\u0027d suggest the following error classification\n\n o storage related\n o flow invariants related\n o job related\n\nAlso, WrappedFailure stands aside (as it does in current patchset, completely agree with you here).\n\nHow it differs with current patchset?\n\nFist, imo there should not be \"generic\" exceptions, like invariant violations, or connection failures. If we failed to connect to job backend, that should JobException, if job was not found that should also be JobException. So, if we tried to e.g. claim a job but something happend we can catch the only exception, JobException. Same with storage: anything that happens wrongly with persistence backends should lead to StorageFailure, was it connection problems, version incompatibilities or whatever.\n\nI\u0027d also suggest to make InvariantViolation to be devoted exclusively to flow invariant failures, like duplicate atom names, missing dependencies, dependency cycles and so on. This way, NotFould becomes InvariantViolation -- something like runtime equivalent of MissingDependency. Also, EmptyFlow looks very much like InvariantViolation to me.\n\nBtw, I\u0027d like to amend to Changbin\u0027s comment on previous patchset: we now have JobException and FlowException, but StorageFailure. Can we have only one word for generic exception classes? In fact, I like Error most, because it\u0027s the shortest, but I\u0027ll be happy with any.","accounts_in_message":[],"_revision_number":7},{"id":"a1bfeede1d8c359381da6b9414b6a52bb2999c16","author":{"_account_id":7366,"name":"Ivan Melnikov","email":"imelnikov@griddynamics.com","username":"imelnikov"},"date":"2014-03-17 09:16:34.000000000","message":"Patch Set 7: I would prefer that you didn\u0027t merge this\n\nForgot to press radio button;)\n\nPlease see my previous comment for complete explanation on why this is -1.\n\nAlso, it worth noting that if you rebase this change on top of https://review.openstack.org/80925 you\u0027ll get nice inheritance diagram in sphinx docs which helps a lot in understanding the results of this change.","accounts_in_message":[],"_revision_number":7},{"id":"2bef835f2255c3e8cd78c5ce5a9ba5c85ebcc9f5","author":{"_account_id":1297,"name":"Joshua Harlow","email":"jxharlow@godaddy.com","username":"harlowja"},"date":"2014-03-17 19:11:25.000000000","message":"Patch Set 7:\n\nSo there would still then be a (Job)NotFound?
