To Reproduce
Try typing a small program. Probably triggerable by any use of macOS and AREPL when typing a variable name that does not exist yet.

Almenon · 2021-04-14T05:36:18Z

I'm not able to reproduce on 3.9 w/ windows. Maybe it's a mac-specific bug?

Can you try running the following in the terminal using python 3.9 please and let me know the output?

from sys import version
print(version)
import asyncio
asyncio.set_event_loop(asyncio.new_event_loop())

Related error: eventlet/eventlet#670

I wonder if this is a internal python bug 🤔

jbarlow83 · 2021-04-14T07:29:46Z

Works fine:

In [1]: from sys import version
   ...: print(version)
   ...: import asyncio
   ...: asyncio.set_event_loop(asyncio.new_event_loop())
3.9.2 (default, Mar 26 2021, 22:33:29)
[Clang 11.0.0 (clang-1100.0.33.17)]

Almenon · 2021-04-14T14:46:50Z

What about

from sys import version
print(version)
import asyncio
asyncio.set_event_loop(asyncio.new_event_loop())
asyncio.set_event_loop(asyncio.new_event_loop())

?

jbarlow83 · 2021-04-14T21:23:21Z

No issue/same output.

Almenon · 2021-04-17T21:48:09Z

I tried to reproduce this on mac el capitan and was unable too. Unfortunately I don't have a mojave-compatible computer so I'm not able to try it there.

How did you run python in the terminal? Can you prefix that command with which so I can see where the executable is please? I'm wondering if the python you're using on the terminal is the same brew python you're using in arepl.

Almenon · 2021-04-17T21:48:50Z

Oh also if you use a earlier version of python does it work with AREPL?

BrandonNav · 2021-04-29T00:49:07Z

What about

from sys import version
print(version)
import asyncio
asyncio.set_event_loop(asyncio.new_event_loop())
asyncio.set_event_loop(asyncio.new_event_loop())

?

I managed to get this working by changing https://github.com/Almenon/AREPL-backend/blob/master/python/arepl_python_evaluator.py#L234

from asyncio.set_event_loop(asyncio.new_event_loop())

to asyncio.set_event_loop(asyncio.get_event_loop())

My environment:
MacOS 11.2.3 (Big Sur)
Python 3.9.3

Almenon · 2021-05-03T01:14:25Z

Really? Very interesting... I'll look into this, thanks!

While I was investigating I also ran into another error: Almenon/AREPL-backend#167

Looks like I have some work to do :|

p-clements · 2021-06-20T12:34:48Z

I've experienced the same bug whilst running a simple script using homebrew Python 3.9.5
However, running the same script on homebrew 3.8.10 works just fine.

Running your script above works fine on both 3.9.5 and 3.8.10

Mac OS 10.15.7 (Catalina)
VSCode 1.57.1

I'm able to reproduce this reliably using just an import statement.
Reverting to Python 3.7.11 makes it work again, as does using Brandon's asyncio.set_event_loop(asyncio.get_event_loop()) fix on 3.9.6.

Environment

OS X 10.13.6
AREPL 2.0.2
VSCodium Version: 1.57.1
Commit: 507ce72a4466fbb27b715c3722558bb15afa9f48
Date: 2021-06-18T00:16:36.917Z (2 wks ago)
Electron: 12.0.7
Chrome: 89.0.4389.128
Node.js: 14.16.0
V8: 8.9.255.25-electron.0
OS: Darwin x64 17.7.0

Steps to reproduce

Create a python file
Open the AREPL pane
Type import requests
Press the Enter key or spacebar
Open and close the ARPL pane
Add a new line: print('hello')
Press the Enter key or spacebar

arepl_keyerror.mp4

If AREPL is restarted, it throws an error when new code is entered (but not when newlines are added). In my case, the KeyError usually mentions key 5, 8, or 11.

Almenon · 2022-05-31T00:11:47Z

Finally got access to a Mac. I can reproduce the bug on 3.9, but the bug does not occur on 3.10. I suggest either using the fix workaround above, downgrading to 3.7, or upgrading to 3.10.

The other interesting thing is that for me this only occurs in the third arepl run.
