Reloading never finishes in certain circumstances (logging a lot of data to terminal)

[ekeric13]

There is a bug in my code and my http server is logging my body to my terminal output. This endpoint contains form data so it is logging MBs worth of binary data.

But this problem is compounded by the fact that is that after i hit this endpoint, when I save any changes in the file, the server never finishes reloading. It will just hang for 5+ minutes before I give up waiting and manually kill the docker container and then rebuild it.

This is essentially the uvicorn setup I am using:
https://github.com/starlite-api/starlite-pg-redis-docker/blob/main/app/main.py#L67-L74

It seems underneath the hood uvicron uses this lib:
https://github.com/samuelcolvin/watchfiles

Please let me know if you think I need to make an issue in there.

Does the file reloading take into account the data written to one's terminal buffer?? I am really confused why I only see this behavior after testing out this one endpoint. I hit other endpoints and then I save the same exact file and it reloads just fine.

edit: Confirmed when I fixed the issue of logging to stdout the very large body the reloading worked again.

a minimal reproductible example would help, from the description you make I fail at seeing where it could hang

So I wasn't able to reproduce with a basic repo :(
https://github.com/ekeric13/starlite-pg-redis-docker/tree/issue-with-reloading

cp .env.example .env

docker-compose up

curl --request POST \
  --url http://0.0.0.0:9000/v1/authors \
  --header 'content-type: multipart/form-data' \
  --form data=@/Users/erickennedy/Documents/data.zip

I guess there is something more that my code is doing. The reloading is also much faster in this repo. Might try re-creating my docker image from scratch.

Okay I will try and reproduce in that repo but i think i found the key reason why i couldn't reproduce it: it is only happening when i am using vscode + debugpy to attach a remote debugger. When i run the code without a remote debugger it reloads fine.

has issues:

PYDEVD_DISABLE_FILE_VALIDATION=1 python -m debugpy --wait-for-client --listen 0.0.0.0:5679 -m uvicorn app.main:app --log-level $UVICORN_LOG_LEVEL --timeout-keep-alive $UVICORN_KEEPALIVE --host $UVICORN_HOST ${UVICORN_RELOAD:+--reload} --port $UVICORN_PORT

works fine

uvicorn app.main:app --log-level $UVICORN_LOG_LEVEL --timeout-keep-alive $UVICORN_KEEPALIVE --host $UVICORN_HOST ${UVICORN_RELOAD:+--reload} --port $UVICORN_PORT
