Guobao Chen updated TINKERPOP-2540:
-----------------------------------
Description:
After installing latest (tinkerpop version 3.4.10), it's found that running a
specific gremlin script with 'count()' step gives unexpected result.
*Steps to reproduce*
1 Install tinkerpop 3.4.10, and connect to this server with gremlin console
client
2 create a modern graph with TinkerFactory
{code:java}
gremlin> graph = TinkerFactory.createModern()
==>tinkergraph[vertices:6 edges:6]
gremlin> g=graph.traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]{code}
3 run following script:
{code:java}
gremlin>
g.V().hasLabel('person').has('name','testuser1').or().has('name','testuser1').values('name','age').dedup().count()
{code}
Note that usser 'testuser1' doesn't exist in the created 'modern' graph.
*Expected result*
a numeric number showing the count (or 0 if there is no vertices from previous
steps before count() step)
*Actual result*
See a list of vertices:
{code:java}
gremlin>
g.V().hasLabel('person').has('name','testuser1').or().has('name','testuser1').values('name','age').dedup().count()
==>v[1]
==>v[2]
==>v[3]
==>v[4]
==>v[5]
==>v[6]{code}
