[Zope3-dev] Re: Releasing Zope 3.4

[Martin Aspeli]

FWIW, and in case it's helpful to someone, below is a (bash) script I 
use to release the eggs I manage for Plone. Nothing magical at all, but 
it's worked well for me.

It's semi-automatic, meaning that it asks you to review each step before 
an svn commit.

I use 'ploneout', a zc.buildout of Plone 3, which puts all eggs in a 
src/ sub-directory. I run this script from that directory, using

$ ./release-egg.sh plone.portlets 1.0b1 1.0b2

That means, release plone.portlets (which is the egg name, and also the 
directory name where the source egg is found) version 1.0b1, uploading 
it to the cheeseshop with an egg and a source tarball, from a tag with 
the name /tags/1.0b1. After completion, trunk is set to version 1.0b2, 
for continued development.

It's worked pretty well for two Plone pre-releases. With this script, it 
takes me 15-20 minutes to release 12 or so eggs. If I removed some of 
the safeguards, which ask to review svn diffs before commits, it'd 
probably cut the time in half.

Usual caveats apply, of course. :)
