An egg index proxy

Project description

What is collective.eggproxy ?

collective.eggproxy is a smart mirror for PyPI.

It will collect packages on PyPI only when a program like easy_install or zc.buildout asks for it. In other words, unlike some mirrors that act like rsync and get the whole PyPI base (more than 5 gigas) collective.eggproxy will only get what you need.

At first run collective.eggproxy downloads pypi index and builds a page of links. When a software asks for a specific package, version, etc. collective.eggproxy downloads it if needed and store it locally.

How to use collective.eggproxy ?

After it has been installed, you can just launch it as a standalone server like this:

$ eggproxy_run

The proxy will then ben available on the localhost on the port 8888. All package will be downloaded by default into /var/www. If this directory does not exists (or if you are under windows), you will need to configure it, as explained in the next section.

From there you can use it in easy_install like this:

easy_install -i http://localhost:8888/ iw.fss

The iw.fss package will be downloaded, stored locally and provided to easy_insall.

In zc.buildout, just define the index value in the buildout section:


index = http://localhost:8888/

That’s it !

Advanced configuration

collective.eggproxy can use a configuration file:

Currently its location is fixed at /etc/eggproxy.conf and looks like this:

eggs_directory = /path/to/pypi
index =

# update information for files older than 24h
update_interval = 24

If /etc/eggproxy.conf is not found, it will look into your home folder, so you can alternatively put this configuration file in your home directory, which can be convenient under Windows.

Using the proxy behind Apache

You can also use collective.eggproxy with Apache. You will need for that mod_python 3.3 for apache. It will not work with previous versions.

Debian Etch users: Etch provides 3.2, so users of Etch must get the source package from “Lenny” (testing) and rebuild it with dpkg-buildpackage. Please have a look at the related section in this document to get some help.

An Apache setup for http://servername/pypi can be:

Alias /pypi "/path/to/pypi"
<Directory "/path/to/pypi">
    Order allow,deny
    Allow from all
    SetHandler mod_python
    PythonFixupHandler collective.eggproxy.apache_handler::fixup_handler
    PythonInterpreter main_interpreter
    PythonOption URLPrefix /pypi
    PythonPath "sys.path+['/path/to/collective.eggproxy']"

Apache must be able to write to “/path/to/pypi”! (usually Apache user is www-data). For updating proxied egg information you must add the script eggproxy_update into the crontab of this user.

mod_python update on Debian Etch

Quick build instructions from debian “lenny” sources:

$ sudo apt-get build-dep libapache2-mod-python
$ sudo apt-get install fakeroot

Visit and grab the files with these extensions:

  • .dsc

  • .orig.tar.gz

  • .diff.gz

$ wget
$ wget
$ wget
$ tar xpvzf libapache2-mod-python_3.3.1.orig.tar.gz
$ cd mod_python-3.3.1/
$ gzip -dc ../libapache2-mod-python_3.3.1-3.diff.gz |patch -p1
$ chmod +x debian/rules
$ dpkg-buildpackage -rfakeroot -b
$ cd ..

you should have the following files:

  • libapache2-mod-python_3.3.1-3_i386.deb

  • libapache2-mod-python-doc_3.3.1-3_all.deb

The last step is calling dpkg:

$ sudo dpkg -i libapache2-mod-python_3.3.1-3_i386.deb


0.2.0 (2008-09-22)

  • package index/download files: skip modules installed in local system (resulted in copying a directory instead of downloading a file)

  • fixed Update script crashing with invalid/obsolete package name

  • Overriden PackageIndex so that we get eggs distributions for all versions, all platforms

  • fixed malformed tag in generated indexes

0.1.0 (2008-06-06)
