Yang Xia created TINKERPOP-2939:
-----------------------------------
Summary: The Merge onMatch map validation is during execution
instead of construction
Key: TINKERPOP-2939
URL: https://issues.apache.org/jira/browse/TINKERPOP-2939
Project: TinkerPop
Issue Type: Improvement
Components: process
Affects Versions: 3.6.3
Reporter: Yang Xia
A small thing I noticed related to TINKERPOP-2931.
With an empty graph, the traversal
{code:java}
g.mergeV([:]).option(onMatch, ['~label', 'vertex']) {code}
will create a new vertex, and since onMatch failed it doesn't apply anything
inside regardless if it's a valid map or not, and will return
{code:java}
v[0]{code}
This won't have any impact function-wise, since the onMatch map will be
validated when the vertex is found, but just wondering if we should validate
this on construction instead of execution?
A more visual example on 3.6.3-SNAPSHOT console.
{code:java}
gremlin> g.mergeV([:]).option(Merge.onMatch, ['~label':'vertex'])
==>v[0]
gremlin> g.mergeV([:]).option(Merge.onMatch, ['~label':'vertex'])
Property key can not be a hidden key: ~label
Type ':help' or ':h' for help.
Display stack trace? [yN]n
