PIP Proxy (pipproxy) is a WSGI Server that acts as a front end for PIP that caches PyPI index and tarballs.

This is not just a simple PyPI index cache. It caches the result of all versions that pip finds, including those hosted outside of PyPI.

pip 1.0 or higher is required.

Check using:

pip --version

Upgrade using:

pip install --upgrade pip

To run the wsgi server, run:

mkdir /tmp/pip_proxy_cache
PIPP_CACHE_DIR=/tmp/pip_proxy_cache python pipproxy/server.py 8008

To use it for all your pip installs:

export PIP_INDEX_URL=http://localhost:8008/simple
pip install foobar-package

Just use the pipproxy.wsgi module. For example, to use it with gunicorn:

PIPP_CACHE_DIR=/tmp/pip_proxy_cache \
  gunicorn -b 127.0.0.1:8008 --timeout=600 pipproxy.wsgi

• optimize caching of package index: do not refresh at /simple/<package_name>/ but only do so at /simple/<package_name>/<version> if version is not found
• potential race condition of two clients requesting the same package or distribution file that is not cached
• for distribution files that are not yet cached, stream them to client while it is being downloaded
