Tags2sdists creates python sdists from tags into a structure that can serve as
a company-internal pypi (python package index).
Setup
Installing tags2sdists itself is as simple as pip install tags2sdists or
easy_install tags2sdists or including it in your buildout in the regular
manner.
Next you need the CHECKOUTDIR and SDISTDIR directories.
CHECKOUTDIR: you need a directory with checkouts. So doing it by hand is
fine. But when you use svn, a directory with svn:externals is probably
handiest. For everything else (and also for svn), checkoutmanager is the thing I’d use. Make a
config file (checkoutmanager.cfg) looking like this:
[internalprojects]
vcs = git
basedir = /srv/packages/var/checkouts/
checkouts =
git@github.com:lizardsystem/nensskel.git
git@github.com:lizardsystem/lizard-ui.git
git@github.com:lizardsystem/tags2sdists.git
And set up a cron job that runs checkoutmanager --configfile=YOURCONFIGFILE, it’ll update the checkouts in the base dir you
configured. (In that same cronjob, fire up tags2sdists afterwards).
SDISTDIR: just a directory somewhere will do. You’ll get a pypi-like
directory structure in there.
A structure like generated with tags2sdists is a perfect index for
easy_install and buildout if you let apache host it. Only problem: you can
only have one index (note: pip apparently supports multiple indexes). You can
solve this problem by having apache redirect you to pypi when something is not
found.
Here’s an example apache config snippet:
# Allow indexing
Options +Indexes
IndexOptions FancyIndexing VersionSort
# Start of rewriterules to use our own var/private/* packages
# when available and to redirect to pypi if not.
RewriteEngine On
# Use our robots.txt:
RewriteRule ^/robots.txt - [L]
# Use our apache's icons:
RewriteRule ^/icons/.* - [L]
# We want OUR index. Specified in a weird way as apache
# searches in a weird way for index.htm index.html index.php etc.
RewriteRule ^/index\..* - [L]
# Use our var/private/PROJECTNAME if available,
# redirect to pypi otherwise:
RewriteCond /path/on/server/var/private/$1 !-f
RewriteCond /path/on/server/var/private/$1 !-d
RewriteRule ^/([^/]+)/?$ http://pypi.python.org/pypi/$1/ [P,L]
# Use our var/private/PROJECTNAME/project-0.1.tar.gz if available,
# redirect to pypi otherwise:
RewriteCond /path/on/server/var/private/$1 !-d
RewriteRule ^/([^/]+)/([^/]+)$ http://pypi.python.org/pypi/$1/$2 [P,L]
Using the apache-served index
You can use such a custom apache-served index in two ways. Easy_install has a
-i option for passing along an index:
$> easy_install -i http://packages.my.server/ zest.releaser
In buildout, you can set it like this:
[buildout]
index = http://packages.my.server/
parts =
...
