Updates the Docker configuration to use the gunicorn server with gevent
workers by default. Adds `waitress` to the docker container, so that if
no server is specified, we will fall back to that rather than `wsgiref`.
Making this happen brought a few other issues to light, which are also
addressed here.
- Docker log output not immediately being flushed to stdout (#358):
resolved by setting the `PYTHONUNBUFFERED` env var to `t` in the
docker container
- When the WSGIRef server is selected, its access logs are written
directly to stderr, rather than going through the logging machinery:
resolved by adding a new `WsgiHandler` class and passing in to
bottle's `run()` method when running the wsgi server. This required a
new `ServerCheck` class to determine whether the wsgi server is
selected when the `auto` option is used
- When using `gunicorn` along with the watchdog cache, package uplaods
were not being picked up by the watcher. Updated the `add_package`
and `remove_package` methods on the `CachingFileBackend` to bust the
cache
This directory contains resources and tests for the docker image.
Note that for these tests to run, the pytest process must be able to run
docker. If you are on a system where that requires sudo, you will need to
run the tests with sudo.
Tests are here rather than in /tests because there's no reason to run these
tests as part of the usual tox process, which is run in CI against every
supported Python version. We only need to run the Docker tests once.
