Root Cause

Hot reload watches a directory written to by the app itself (logs, sqlite, uploads), triggering an endless reload loop.

generic

中文

热重载监视的目录被应用自身写入（日志、sqlite、上传），触发无限重载循环。

Workarounds

  1. 93% success 
    uvicorn app.main:app --reload --reload-exclude '*.log' --reload-exclude 'data/*'
  2. 90% success 
    LOG_DIR = os.environ.get('LOG_DIR', '/var/log/myapp')

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Loop resumes once the app writes again.

  2. 85% fail

    Suppresses log output but watcher still fires.
