ASF GitHub Bot commented on TINKERPOP-1862: ------------------------------------------- Github user PBGraff commented on the issue: https://github.com/apache/tinkerpop/pull/801 Done > TinkerGraph VertexProgram message passing doesn't work properly when using > Direction.BOTH > ----------------------------------------------------------------------------------------- > > Key: TINKERPOP-1862 > URL: https://issues.apache.org/jira/browse/TINKERPOP-1862 > Project: TinkerPop > Issue Type: Bug > Components: process, tinkergraph > Affects Versions: 3.2.7 > Reporter: Philip Graff > Priority: Major > > I think the messages are being sent properly in TinkerMessenger, but when I > call messenger.receiveMessages(), the vertex is getting messages from the > outVertex of their edges regardless of the edge direction. This is due to > line 71 of TinkerMessenger (linked below) which calls > Edge.vertices(direction).next(), thus getting the first result out of the > Vertex iterator. For IN or OUT, this isn't a problem. But for BOTH, following > line 124 of TinkerEdge (linked below), the outVertex is always returned > first. TinkerMessenger needs to be modified to return the correct vertex (I > think it's the one that != this.vertex). > https://github.com/apache/tinkerpop/blob/master/tinkergraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/tinkergraph/process/computer/TinkerMessenger.java#L71 > https://github.com/apache/tinkerpop/blob/master/tinkergraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/tinkergraph/structure/TinkerEdge.java#L124 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
