Stephen Mallette updated TINKERPOP-2499:
----------------------------------------
Summary: PathRetractionStrategy returns inconsistent results when match()
is not detected as the final step (was: PathRetractionStrategy returns
inconsistent results when identity() follows match())

> Key: TINKERPOP-2499
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2499
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.4.9
> Reporter: Stephen Mallette
> Priority: Major
>
> This issue comes from TINKERPOP-2481 where it was originally noted that
> perhaps {{IdentityRemovalStrategy}} had something to do with the following:
> {code}
> gremlin> g.V().match(__.as("a").out("knows").as("b")).identity()
> ==>[]
> ==>[]
> gremlin>
> g.withStrategies(IdentityRemovalStrategy.instance()).V().match(__.as("a").out("knows").as("b")).identity()
> ==>[a:v[1],b:v[2]]
> ==>[a:v[1],b:v[4]]
> gremlin>
> g.withoutStrategies(PathRetractionStrategy).V().match(__.as("a").out("knows").as("b")).identity()
> ==>[a:v[1],b:v[2]]
> ==>[a:v[1],b:v[4]]
> {code}
> but it is not a good idea to fix the behavior of one strategy by way of
> another so {{PathRetractionStrategy}} needs to get a bit smarter.
