Description

If a cyclic dependency is introduced between a namespace and itself, it results in a StackOverflow when calculating transitive-dependencies.

(transitive-dependencies (-> (graph)
                             (depend 'two 'two))
                         'two)
; => StackOverflow

I believe clojure.tools.namespace.dependency/transitive should maintain a set of seen namespaces and check if we have already seen the namespace at each step.

Already fixed in 0.2.4-SNAPSHOT by forbidding cyclic dependencies: https://github.com/clojure/tools.namespace/commit/85e73af04fdb497db1600ef3bf21aef5ed676619
