-----------------------------------

             Summary: Unused hashmap::existsValue functions have incomplete code paths
                 Key: MESOS-3329
                 URL: https://issues.apache.org/jira/browse/MESOS-3329
             Project: Mesos
          Issue Type: Bug
          Components: stout
            Reporter: Jan Schlicht
            Priority: Trivial


`stout/hashmap.hpp` defines functions `hashmap::existsValue`. These return true if a certain value exists in the hashmap instance. The control flow of these functions doesn't cover the case that the value is not found, which should result in false. Right now the result in this case is undefined.
As the `existsValue` functions are never called this doesn't result in a compile error atm.
Possible solutions:
1) Add `return false`
2) Remove function
