# Falcon + zipfile streaming content using os.pipe() to minimize RAM usage to a
# pipes worth of data.
#
# This test program generated a nearly 500 MB zip file with various compression
# arguments supported by the python3 standard library.
#
# Usage for debug webserver:
# $ ./app.py

# Run this tool and feed it stuff.
# $ python3 udp-test.py
#
# Emulate a remote client sending data:
# $ cat /dev/urandom | nc -u 127.0.0.1 7502
#
# Cancel netcat and try again, second attempt will fail because the source port
# likely changed (not guaranteed, but statistically likely)

# Proof of Concept
#
# Compose a docker image of an upstream images so that binaries packages in one
# image can be incorporated into another.
#
# TODO This copies, would be nice if there was a way to attach an image to a
#      container like `docker run --volumes-from` does for containers.

# These FROMs used as a way to distribute files via an image
