-------------------------------------------
Summary: Consistent behavior of self-referencing edges
Key: TINKERPOP-1821
URL: https://issues.apache.org/jira/browse/TINKERPOP-1821
Project: TinkerPop
Issue Type: Bug
Components: process
Affects Versions: 3.2.6
Reporter: stephen mallette
Assignee: Marko A. Rodriguez
Given discussions here:
https://lists.apache.org/thread.html/adcfa13130026896da215be257fd26b309820c1cd5b5d359ed9cdfa2@%3Cdev.tinkerpop.apache.org%3E
we needed to include a test to ensure consistency of the traversal behavior
around self-referencing edges in relation to
{code}
g.V().bothE()
g.V().both()
{code}
The expected behavior is already present in TinkerGraph and that expected
behavior is as follows:
{code}
gremlin> g.addV().as("a").addE("self").to("a").iterate()
gremlin> g.V().bothE()
==>e[19][18-self->18]
==>e[19][18-self->18]
gremlin> g.V().both()
==>v[18]
==>v[18]
{code}
This may break a number of providers as we've not had a test for this behavior
until now - we should provide some upgrade documentation to call attention to
this issue.
