Clément de Groc commented on TINKERPOP-3040:
--------------------------------------------
I'm not too familiar with this part of the codebase and would appreciate any
insights (cc [~kenhuuu], [~ryn1]).
AFAIU, remote scripts are evaluated twice since TinkerPop 3.7.1:
# First locally
[here|https://github.com/apache/tinkerpop/blob/3.7-dev/gremlin-console/src/main/groovy/org/apache/tinkerpop/gremlin/console/GremlinGroovysh.groovy#L118]
- to handle multiline scripts IIUC
(https://issues.apache.org/jira/browse/TINKERPOP-2999,
[https://github.com/apache/tinkerpop/pull/2297]).
# Then remotely
[here|https://github.com/apache/tinkerpop/blob/3.7-dev/gremlin-console/src/main/groovy/org/apache/tinkerpop/gremlin/console/GremlinGroovysh.groovy#L147],
if the local execution succeeded or raised a {{MissingPropertyException}}
(https://issues.apache.org/jira/browse/TINKERPOP-3013,
[https://github.com/apache/tinkerpop/pull/2341]).
In the two errors shared above, I think the script will throw a
{{RuntimeException}} locally, causing remote execution to be skipped.
Is there a way to avoid the local evaluation while preserving multiline scripts?
