---------------------------------------------
Summary: Solve the child traversal clone problem.
Key: TINKERPOP-1186
URL: https://issues.apache.org/jira/browse/TINKERPOP-1186
Project: TinkerPop
Issue Type: Bug
Components: process
Affects Versions: 3.1.1-incubating
Reporter: Marko A. Rodriguez
Assume the following traversals.
{code}
root = [RepeatStep([VertexStep,PropertiesStep])]
child = [VertexStep,PropertiesStep]
{code}
where child is inside of root.
Right now if you {{child.clone()}}, root is not cloned and thus, if you have
multiple clone'd children, they all share the same root.
This is bad as this is not a legitimate clone. We have never run into any bugs
around this because all our code clones root traversals. However, when we
introduced {{XXXVertexProgramStep}}, where children are cloned to the
respective {{XXXVertexProgram}}, the problem emerged. We have a some
workarounds currently, but we should really solve the general problem of
ensuring the you get both an "up and down"-cascading clone.
