[jira] [Commented] (TINKERPOP-1528) CountByIsRangeStrategy fails for a particular query

["Marko A. Rodriguez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP-1528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15848672#comment-15848672 ] 

Marko A. Rodriguez commented on TINKERPOP-1528:
-----------------------------------------------

I just verified that this problem still exists in the {{tp32/}} line.

{code}
gremlin> g.V().count().is(0)
gremlin> g.V().count().is(0).explain()
==>Traversal Explanation
=========================================================================================
Original Traversal                 [GraphStep(vertex,[]), CountGlobalStep, IsStep(eq(0))]

ConnectiveStrategy           [D]   [GraphStep(vertex,[]), CountGlobalStep, IsStep(eq(0))]
RangeByIsCountStrategy       [O]   [NotStep([GraphStep(vertex,[])])]
...

>    Affects Versions: 3.2.3

> In a fresh TinkerGraph:
> {noformat}
> gremlin> g.V().count()
> ==>0
> gremlin> g.V().count().is(0)
> gremlin>
> {noformat}
> Because of {{.is(0)}} the traversal is converted to something like {{g.not(V())}}. No issues with other values (!= 0).
> {noformat}
> gremlin> g.addV()
> ==>v[0]
> gremlin> g.V().count()
> ==>1
> gremlin> g.V().count().is(0)
> gremlin> g.V().count().is(1)
> ==>1
> gremlin> g.V().count().is(2)
> gremlin>
> {noformat}
