stephen mallette commented on TINKERPOP-1684: --------------------------------------------- This issue could have some relation to TINKERPOP-1693 as the use of {{tree()}} with {{by()}} seems to open up the chance for bad stuff to happen. > Improper results with union() in a by() > --------------------------------------- > > Key: TINKERPOP-1684 > URL: https://issues.apache.org/jira/browse/TINKERPOP-1684 > Project: TinkerPop > Issue Type: Bug > Components: process > Affects Versions: 3.2.4 > Reporter: stephen mallette > > There are some odd results when using a {{union()}} inside a {{by()}}. These > problems were initially found in {{tree().by()}} as follows: > {code} > gremlin> g.V(1).repeat(out()).emit().tree().next() > ==>v[1]={v[2]={}, v[3]={}, v[4]={v[3]={}, v[5]={}}} > gremlin> g.V(1).repeat(out()).emit().tree().by('name').next() > ==>marko={vadas={}, josh={ripple={}, lop={}}, lop={}} > gremlin> > g.V(1).repeat(out()).emit().tree().by(union(__(),repeat(out()).emit().count()).fold()).next() > ==>[0, v[1], 5]={[0, v[4], 2]={[0, v[5]]={}}} > ==>[v[1], 5]={[0, v[2]]={}, [0, v[3]]={}, [0, v[4], 2]={[0, v[3]]={}}} > {code} > For some reason the final traversal returns two entries to tree where there > are extra "0" values in the lists that we can't seem to account for. So, i > suppose this is either a bug or we need some explanation for why the extra > zeroes are there. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
