Module `Property_status.Consolidation`

Consolidation of a property status according to the (consolidated) status of the hypotheses of the property.

type pending =
  Property.Set.t Emitter.Usable_emitter.Map.t Emitter.Usable_emitter.Map.t

who do the job and, for each of them, who find which issues.

type consolidated_status = private

| Never_tried
(*
Nobody tries to verify the property. The argument is for internal use only
*)
| Considered_valid
(*
Nobody succeeds to verify the property, but it is expected to be verified by another way (manual review, ...)
*)
| Valid of Emitter.Usable_emitter.Set.t
(*
The verification of this property is fully done. No work to do anymore for this property. The argument is the emitters who did the job.
*)
| Valid_under_hyp of pending
(*
The verification of this property is locally done, but it remains properties to verify in order to close the work.
*)
| Unknown of pending
(*
The verification of this property is not finished: the property itself remains to verify and it may also remain other pending properties. NB: the pendings contains the property itself.
*)
| Invalid of Emitter.Usable_emitter.Set.t
(*
The verification of this property is fully done. All its hypotheses have been verified, but it is false: that is a true bug.
*)
| Invalid_under_hyp of pending
(*
This property is locally false, but it remains properties to verify in order to be sure that is a bug.
*)
| Invalid_but_dead of pending
(*
This property is locally false, but there is other bugs in hypotheses
*)
| Valid_but_dead of pending
(*
This property is locally true, but there is bugs in hypotheses
*)
| Unknown_but_dead of pending
(*
This property is locally unknown, but there is other bugs in hypotheses
*)
| Inconsistent of string
(*
Inconsistency detected when computing the consolidated status. The string explains what is the issue for the end-user.
