[jira] [Commented] (TINKERPOP-2797) graph_traversal V() throws on IDs larger than 2^31

["Yang Xia (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP-2797?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17602040#comment-17602040 ] 

Yang Xia commented on TINKERPOP-2797:
-------------------------------------

Hi [~pkemkes] , thank you for raising the issue. This new error is due to the change in the default serialization format for python in 3.6.1 from GraphSON to GraphBinary, which is more strict in the number typing.

To bypass the error you could either change the serializer back to GraphSON when you create the drc:
g = traversal().withRemote(connection, message_serializer=gremlin_python.driver.serializer.GraphSONMessageSerializer())
(additional details see [https://tinkerpop.apache.org/docs/3.6.1/reference/#gremlin-python-configuration)]

Or you could use the `long()` helper converter from `statics.py`, to convert large numerical requests:
print(f"2147483647: \{g.V(gremlin_python.statics.long(2147483647)).hasNext()}")

> Hi,
> we've noticed that graph_traversal.py's V() does not take IDs larger or equal to 2^31 from version 3.6.1 on. It still worked on version 3.6.0.
> The following code replicates the issue:
> {code:java}
> g = traversal().withRemote(connection)
> print(f"2147483647: {g.V(2147483647).hasNext()}")
> print(f"2147483648: {g.V(2147483648).hasNext()}") {code}
> On version 3.6.0 it produces the following output:
> {code:java}
> 2147483647: False
> 2147483648: True{code}
> Note: The first ID does not exist in our graph, the latter does.
> On version 3.6.1, it crashes and the following output is created:
> {code:java}
> 2147483647: False
> Traceback (most recent call last):
