Stephen Mallette reassigned TINKERPOP-2491: ------------------------------------------- Assignee: (was: Stephen Mallette) > Improve consistency of the output of range() oriented steps > ----------------------------------------------------------- > > Key: TINKERPOP-2491 > URL: https://issues.apache.org/jira/browse/TINKERPOP-2491 > Project: TinkerPop > Issue Type: Improvement > Components: process > Affects Versions: 3.4.9 > Reporter: Stephen Mallette > Priority: Major > Labels: breaking > > As pointed out here: > https://groups.google.com/g/gremlin-users/c/OvxKvvM8rXs/m/slnv6cWpBQAJ > there is an automatic {{List}} unfold with {{limit(local, 1)}} as in: > {code} > g.inject([1, 2, 3], [4]).limit(local, 3).toList() // [[1, 2, 3], [4]] > g.inject([1, 2, 3], [4]).limit(local, 2).toList() // [[1, 2], [4]] > g.inject([1, 2, 3], [4]).limit(local, 1).toList() // [1, 4] ??? - Expected > [[1], [4]] > g.inject([1, 2, 3], [4]).limit(local, 0).toList() // [[], []] oh come on > {code} > In addition, `range()` and `tail()` are similarly affected: > {code} > gremlin> g.inject([1, 2, 3], [4]).tail(local, 1).toList() > ==>3 > ==>4 > gremlin> g.inject([1, 2, 3], [4]).range(local, 0, 1).toList() > ==>1 > ==>4 > {code} > Changing this is a fairly imposing breaking change in behavior. We could > mitigate that with a strategy to support the old functionality if folks want > to have that: > {code} > g.withStrategy(OldWayStrategy).inject([1, 2, 3], [4]).limit(local, 1) > {code} > would transform to: > {code} > g.inject([1, 2, 3], [4]).limit(local, 1).unfold() > {code} -- This message was sent by Atlassian Jira (v8.20.1#820001)
