Managing multiple Plone buildouts

I recently had situation in work where I needed to update several of our Plone sites with few addon products. So far we haven't thought how we'll manage our sites update story as we've basically just recently entered to the amazing world of buildouts and several Plone-sites instead of one huge plone-site with zeo. Gotta say I had few ideas popping in my head when I was manually running buildout scripts for each of our sites and stopping and restarting them after buildout was completed. My first though was to just simply write some script which does the job and then I was already imaging some web based service so we could manage our sites buildouts ttw. Well.. that might be a bit overkill.. at least for the starters, so I went back to roots and wrote a small python application which does the job. Basically it just takes the list of buildouts and runs buildout-script with -Nv parameters and restarts the site. Source code is below and in the github . #!/usr/bin/python2.5 from ...

Ubuntu, Plone and problems with openldap and python-ldap

For some reason I've always had problems with python-ldap and openldap with Plone when I'm using Ubuntu. I've always managed to solve the problem by somehow building openldap from sources and been happy ever since. Now with fresh Ubuntu install I bumbed once again to the same problem and decided to write a reminder how I get things working again. This time I used Panyasan's buildout example with one extra environment line. Without that line openldap won't compile on ubuntu. Instead of compiling succesfully it throws me an error "ubuntu getpeereid.c:52: error: storage size of ‘peercred’ isn’t known" Here are the important parts: [buildout] parts = zope2 productdistros instance zopepy openldap python-ldap ...

Plone migration experiences

1. Migrating is fun fun fun! Let's face it - migrating Plone site from old version to new one can be either painful or very painful experience. If you need to do it for one site only, you don't even get the reward of the fact that second time will be so much easier. Third time you'll start wondering what was the hard part in it. This post is intended to be description how we did plone migration from older version to new one with big, live and heavy traffic site . We're still middle of migrating rest of our sites and therefore I'm going to upgrade this description when I'm having more time. Also note that this is written with one go from memory and as doing the migration is quite complex thing to do including many tasks there might be some errors. I hope this gives some ideas to others struggling with the same topic and also raises some discussion why this is so complex to do when it shouldn't. I'm also happy to get comments how we could have done this be...

Plone and multi-site management

CMS Wire recently posted a light weight comparsion of open source CMS and their multi-site management capabilities. According to article none of the three popular CMS ( Plone , Drupal and Joomla ) include multi-site management in their core CMS. Article was more about third party addons and what they have to offer for multi-site management needs. Six Feet Up companys Lineage -product shines on this comparsion with it's easy to use separation of certain folder inside Plone site as independet site with certain users, workflows, theme and navigation. Although Lineage is already released it still has some dependencies which are not met with Plone 3.2.1 (but should be in Plone 3.3), so installation needs some additional lines to buildout. You can find more information from Plone Software Center . In the Plone-sites we're developing and maintaining, we've traditionally wanted to keep sites theme pretty much the same within all different departments and faculties. With Lineage...

About this blog and the writer

I should knock down the barriers and finally put some content to this blog. I intend to make this as my technology biased blog partly as a reminder for myself about things and problems I've encountered and hopefully also solved. About me... I'm Finnish information technology science student currently writing my masters thesis about web site usability. To be exact I'm doing research about usability of Ajax based web applications. My intention is to get some data if much hyped myth that Ajax applications have better usability have actually some ground in it. My research application is Plone web CMS (Content Management System) which is probably best open source web CMS currently available. Reasons for me picking this certain web application is my backgrounds as a Plone developer in University of Jyväskylä . I've been working with Plone since Autumn 2006 and in that time I've managed to do quite a few things with Plone from translating ready products to developing new...
