DjangoPyPI

DjangoPyPI is a Django application that provides a re-implementation of the Python Package Index.

Installation

Path

The first step is to get djangopypi into your Python path.

Buildout

Simply add djangopypi to your list of eggs and run buildout again it should downloaded and installed properly.

EasyInstall/Setuptools

If you have setuptools installed, you can use easy_install djangopypi

Manual

Download and unpack the source then run:

$ python setup.py install

Django Settings

Add djangopypi to your INSTALLED_APPS setting and run syncdb again to get the database tables [1].

Then add an include in your url config for djangopypi.urls:

urlpatterns = patterns("",
    ...
    url(r'', include("djangopypi.urls"))
)

This will make the repository interface be accessible at /pypi/.

Package upload directory

By default packages are uploaded to <MEDIA_ROOT>/dists so you need both to ensure that MEDIA_ROOT is assigned a value and that the <MEDIA_ROOT>/dists directory is created and writable by the web server.

You may change the directory to which packages are uploaded by setting DJANGOPYPI_RELEASE_UPLOAD_TO; this will be a sub-directory of MEDIA_ROOT.

Other settings

Look in the djangopypi source code for settings.py to see other settings you can override.

Data initialisation

Load the classifier database with the management command:

$ python manage.py loadclassifiers

Package download handler

Packages are downloaded from the following URL: <host>/simple/<package>/dists/<package>-<version>.tar.gz#<md5 hash>

You will need to configure either your development server to deliver the package from the upload directory, or your web server (e.g. NGINX or Apache).

To configure your Django development server ensure that urls.py looks something like following:

import os
from django.conf.urls import patterns, include, url
from django.conf import settings

# ... other code here including Django admin auto-discover ...

urlpatterns = patterns('',
    # ... url patterns...

    url(r'^simple/[\w\d_\.\-]+/dists/(?P<path>.*)$', 'django.views.static.serve',
            {'document_root': os.path.join(settings.MEDIA_ROOT,
                                           settings.DJANGOPYPI_RELEASE_UPLOAD_TO)}),
    url(r'', include("djangopypi.urls")),

    # .. url patterns...
)

This should only be used for the Django development server.

When using a web server, configure that to deliver packages from the upload dist directory directly from this URL. For example, you may have a clause in an NGINX configuration file something like the following:

server {
  ... configuration...

  location ~ ^/simple/[a-zA-Z0-9\,\-\.]+/dists/ {
      alias /path/to/upload/dists/;
  }

  ... configuration...
}

Uploading to your PyPI

Assuming you are running your Django site locally for now, add the following to your ~/.pypirc file:

[distutils]
index-servers =
    pypi
    local

[pypi]
username:user
password:secret

[local]
username:user
password:secret
repository:http://localhost:8000/pypi/

Uploading a package: Python >=2.6

To push the package to the local pypi:

$ python setup.py register -r local sdist upload -r local

Uploading a package: Python <2.6

If you don't have Python 2.6 please run the command below to install the backport of the extension for multiple repositories:

$ easy_install -U collective.dist

Instead of using register and dist command, you can use mregister and mupload which are a backport of python 2.6 register and upload commands that supports multiple servers.

To push the package to the local pypi:

$ python setup.py mregister -r local sdist mupload -r local

[1]	djangopypi is South enabled, if you are using South then you will need to run the South migrate command to get the tables.

Installing a package with pip

To install your package with pip:

$ pip install -i http://my.pypiserver.com/simple/ <PACKAGE>

If you want to fall back to PyPi or another repository in the event the package is not on your new server, or in particular if you are installing a number of packages, some on your private server and some on another, you can use pip in the following manner:

$ pip install -i http://localhost:8000/simple/ \
  --extra-index-url=http://pypi.python.org/simple/ \
  -r requirements.txt

(substitute your djangopypi server URL for the localhost one in this example)

The downside is that each install of a package hosted on the repository in --extra-index-url will start with a call to the first repository which will fail before pip falls back to the alternative.
