------------------------------------------
Fix Version/s: (was: 3.1.1-incubating)
3.2.0-incubating
> GroupSideEffectStep doesn't use provided maps
> ---------------------------------------------
>
> Key: TINKERPOP-1057
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1057
> Project: TinkerPop
> Issue Type: Bug
> Components: process
> Affects Versions: 3.0.2-incubating
> Reporter: Daniel Kuppitz
> Assignee: Marko A. Rodriguez
> Fix For: 3.2.0-incubating
>
>
> {{GroupSideEffectStep}} doesn't seem to use maps that are provided via
> {{withSideEffect()}}.
> Here's what we expect (note that this is {{groupCount}}, which works fine):
> {noformat}
> gremlin> g = TinkerFactory.createModern().traversal()
> ==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
> gremlin> m = ["marko":1L]; g.withSideEffect("m",
> m).V().groupCount("m").by("name").iterate(); m
> ==>marko=2
> ==>vadas=1
> ==>lop=1
> ==>josh=1
> ==>ripple=1
> ==>peter=1
> {noformat}
> Now the same using {{group}}:
> {noformat}
> gremlin> m = ["marko":1]; g.withSideEffect("m",
> m).V().group("m").by("name").by(constant(1).sum()).iterate(); m
> ==>marko=1
> {noformat}
> This is the first issue; {{group()}} doesn't update the map entries at all.
> However, if we use {{cap()}}, we can see a different behavior:
> {noformat}
> gremlin> m = ["marko":1]; g.withSideEffect("m",
> m).V().group("m").by("name").by(constant(1).sum()).cap("m").next()
> ==>marko=1
> ==>ripple=1
> ==>peter=1
> ==>vadas=1
> ==>josh=1
> ==>lop=1
> gremlin> m
> ==>marko=1
> ==>ripple=1
> ==>peter=1
> ==>vadas=1
> ==>josh=1
> ==>lop=1
> {noformat}
> This would be the correct result with no provided initial {{m}}, but since we
> initialized {{marko}} with {{1}}, the result should contain {{marko=2}}, as
> shown in the {{groupCount()}} example above.
