S3 bug demo

A demo of the bug described in this blog post.

To reproduce:

  1. Make a new virtualenv and activate it
  2. pip install -r requirements.txt
  3. Start a moto server in the background: moto_server s3bucket_path &. Moto is a library that implements a fake s3 for use in testing.
  4. Run python create_test_object.py. This will write a gigabyte of random data to a test key in the moto s3 (in memory, so make sure you have a least a GB of memory available)
  5. Run python app.py & to start the flask server in the background.
  6. curl http://127.0.0.1:5001/test > /dev/null to retrieve the GB of random test data and send it to /dev/null. Everything will be fine
  7. curl http://127.0.0.1:5001/test | head -c 10 and watch the memory usage of the server balloon to roughly a gigabyte just after the command returns.
You can’t perform that action at this time.
