Connection reset from API when using Python 3.8

Open mkroman opened this issue 5 years ago • 6 comments

After some testing and some discussion with @er013 it's apparent that there's some kind of silent incompatibility with Python 3.8.x that's not present in Python 3.7.6.

When lbrynet (0.58.1) is started using Python 3.8.1, requests to the API will be met with a connection reset:

@lyoshenka that PR does not solve this particular issue - the PR just makes the lbrynet daemon able to run, but there's still a silent problem with connection resets from the API when using Python 3.8 as described in this issue which I haven't tracked down.

@mkroman Thanks for letting me know. I've reopened the issue. If you do track down a solution, we would be grateful :-)

This error seems to be documented in the aiohttp project.

See https://github.com/aio-libs/aiohttp/issues/5818, https://github.com/aio-libs/aiohttp/issues/4724, https://github.com/aio-libs/aiohttp/issues/3507. In those cases they use Python 3.6 and 3.7, while the error in LBRY is only visible with Python 3.8+.

This issue should be solved with #3362.

The solution is just using a newer aiohttp. I tried aiohttp==3.6.2 because that is the version in the repositories in Ubuntu 20.04. To test I use Python 3.8 in Ubuntu, and Python 3.9 in Arch, and they both seem to work fine.

This issue has been solved. I installed it in a venv running Python version 3.9.9 and everything worked just fine. Out of interest I also (not at the same time) removed all of the required version numbers in setup.py, so it just installed the latest version of each dependency, and everything seemed to be fine. Perhaps you should also consider updating the version numbers?
