-----------------------------------------
Resolution: Fixed
> RepeatUnrollStrategy does not semi-compile inlined repeat traversal
> -------------------------------------------------------------------
>
> Key: TINKERPOP-1472
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1472
> Project: TinkerPop
> Issue Type: Bug
> Components: process
> Affects Versions: 3.2.2
> Reporter: Marko A. Rodriguez
> Assignee: Marko A. Rodriguez
> Fix For: 3.2.3
>
>
> There is a bug in {{RepeatUnrollStrategy}}. Assume the following traversal:
> {code}
> g.V().repeat(outE().inV()).times(2)
> {code}
> This is currently compiled to:
> {code}
> g.V().outE().inV().outE().inV()
> {code}
> It should be compiled to:
> {code}
> g.V().out().out()
> {code}
> What is the problem? {{RepeatUnrollStrategy}} is the first strategy that
> takes a child traversal and injects it into the parent traversal. By doing
> that, any strategies up to that point have not been kicked off and thus, the
> injected traversal sequence isn't privy to all the strategies prior to
> {{RepeatUnrollStrategy}} (e.g. {{IncidentToAdjacentTraversal}}).
> In TINKERPOP-1456 branch, there is the fix as {{InlineFilterStrategy}} was
> created and the bug showed itself there. Thus, when TINKERPOP-1456 is merged
> to master/, close this ticket as "fixed."
