Gremlin Python 3.4.13 - Exception Ignored Message When Existing A Python Main
What Happens
This happens in Gremlin Python 3.4.13
1. Open
client.close() # Let the underlying cleanup for a bit. for in range(5): sleep(0.25) ` Seems to avoid the error.
self.connection = DriverRemoteConnection(url, 'g')
2. Run some Gremlin Queries
2. Close self.connection.close()
4. Exit the Main immediately after the close().
This is what I see thrown on the console.
After Exception ignored in: <function _ProactorBasePipeTransport.del at 0x000001CB0D9232E0>
Traceback (most recent call last):

raise RuntimeError('Event loop is closed')
RuntimeError: Event loop is closed
**What I Was Expecting**
Because I closed it, I would expect no above error should be raised.
May be I am doing this wrong, or there may need to be additional config or set up that I am missing.
** Workaround **
client.close() # Let the underlying cleanup for a bit. for in range(5): sleep(0.25) ` Seems to avoid the error.

i guess we don't block well on
Client.close() - that method does seem to be meant to be synchronous, yet the eventloop is still taking time to shutdown in the background. i think you should create a JIRA for this one so we can investigate further.Yes, I am quite happy to help there in terms of filing tickets and testing if the fix has been made. Let me code up a very short (i.e., just open and close) code to demo this and add that to the ticket.
I will also create a repro for the timestamp case while I am at it.
Could you give me the JIRA endpoint that I should hit?
https://issues.apache.org/jira/projects/TINKERPOP/issues/TINKERPOP-2957?filter=allopenissues
you'll need to request an account, if you don't have one
Checking...
@yangxia_ can push it through for you quickly once you make the request ☝️
Filling the form now.
Ok filled.
We use JIRA ourselves. I am an admin for ours.
Oh if you have an JIRA account you should be able to open ticket in TinkerPop already
Let's see.
Not ASF side, sorry about the confusion. We have our own private JIRA.
Ahh I see
Ours is passwordless.
Ok yea, just waiting for the self-serve request email then. It might be a few minutes
@manabubeach I still don't see any new requests. It might be a delay in the system. I'll monitor the emails, but if you don't get one created by the end of day I'd suggest submitting the request form again https://selfserve.apache.org/jira-account.html
@manabubeach did you ever get a chance to create that JIRA?
Been distracted and not yet, I will try to get to that tomorrow. Just bought another supply of "round-to-it" so will be tomorrow! 😉
