devpi-server: reliable fast pypi.python.org caching server
consistent robust pypi-cache
You can point pip or easy_install to the root/pypi/+simple/ index, serving as a self-updating transparent cache for pypi-hosted and external packages. Cache-invalidation uses the latest and greatest PyPI protocols. The cache index continues to serve when offline and will resume cache-updates once network is available.
Each user can have multiple indexes and upload packages and docs via standard setup.py invocations. Users, indexes (and soon projects and releases) are manipulaed through a RESTful HTTP API.
Each index can be configured to merge in other indexes so that it serves both its uploads and all releases from other index(es). For example, an index using root/pypi as a parent is a good place to test out a release candidate before you push it to PyPI.
good defaults and easy deployment
Get started easily and create a permanent devpi-server deployment including pre-configured templates for nginx and cron.
