Codeintel on KomodoIDE11 fails when using python3 `async with`
Short Summary
When using async with on python3 code, CodeIntel fails
Steps to Reproduce
#!/usr/bin/env python
"""Generic utils for scriptworker.
Attributes:
log (logging.Logger): the log object for the module
"""
import logging
log = logging.getLogger(__name__)
async def download_file(context, url, abs_filename, session=None, chunk_size=128):
"""Download a file, async.
Args:
context (scriptworker.context.Context): the scriptworker context.
url (str): the url to download
abs_filename (str): the path to download to
session (aiohttp.ClientSession, optional): the session to use. If
None, use context.session. Defaults to None.
chunk_size (int, optional): the chunk size to read from the response
at a time. Default is 128.
"""
session = session or context.session
log.info("Downloading %s", url)
async with session.get(url) as resp:
if resp.status != 200:
raise Exception("{} status {} is not 200!".format(url, resp.status))
with open(abs_filename, 'wb') as fd:
while True:
chunk = await resp.content.read(chunk_size)
if not chunk:
break
fd.write(chunk)
log.info("Done")
Expected results
CodeIntel to show me symbols
Actual results
No Symbols found.
Platform Information
Komodo Edit or IDE? IDE Komodo Version? 11.0.2 Operating System (and version)? Ubuntu 16.04.3 LTS
Additional Information
No relevant errors in any logs (with default log verbosity, if I can provide actual debug spewing logs I'm happy to)
Note to self: remove the async and await keywords, and codeintel works properly. It appears the parsers do not account for those keywords yet.
@mitchell-as locally using async def ... and await foo() in local files seems to get python3 (new codeintel not legacy) to work fine in getting symbols, minimally reducing to async with where if I removed async it worked fine.
Related but possibly an issue in itself, I am running Python 3.7 on the affected machine and in this file ..\dbgp\python3lib\dbgp\client.py
the dbgp server/client blows up when it hits functions like def cmdloop(self, async=0) @ l2523 with a syntax error. I went in and changed all of the identifiers async to _async and didn't have any problems. I believe dbgp's protocol has commands with the word async so a find&replace would break the code if changed blindly.
@cgchoffman I think this might be the same as https://github.com/Komodo/KomodoEdit/issues/3592
Hi! Still having the same issue running Komodo IDE, version 12.0.1, build 91869, platform linux-x86_64, built on Mon Feb 10 19:37:24 2020 on Ubuntu 20.04 and Python 3.8.2 The code snippet from https://docs.aiohttp.org/en/stable/client_reference.html can be used for reproducing inappropriate behaviour:
import aiohttp
import asyncio
async def fetch(client):
async with client.get('http://python.org') as resp:
assert resp.status == 200
return await resp.text()
async def main():
async with aiohttp.ClientSession() as client:
html = await fetch(client)
print(html)
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
