Fred van Dijk: Products.CacheSetup 1.2.1 not compatible with Plone 3.3.5

If you are working on a Plone 3 site and are configuring cache setting using Products.Cachesetup, be warned that the latest release might give you some grey hairs.

After installing CacheSetup 1.2.1 on a production Plone and going to the Control Panel I ran into a traceback when visiting the rules page: a str object does not have a text attirbute. Quick solution:

• Uninstall CacheSetup
• Remove portal_cache_settings from your Plone directory if it’s still there
• Make sure your site is using a CacheSetup trunk version after @146125 or a version hight than 1.2.1 if it’s out.
• Reinstall Cachesetup

The problem: CacheSetup has both old python install code in Extensions/install.py and GS cachesettings.xml profiles to create the portal_cache_settings folder with 2 predefined caching policies. The vary_expression field  somehow get’s set to the default string value set in the Archetypes schema instead of an Expression. Check Stefan Holek’s fix he made on trunk on October 13th. I ran into the issue on the 15th andI checked for new releases but didn’t dive into svn trunk. So lesson learned: check SVN trunk of a package first if you run into any problems with it.

What baffled me and my colleague Maurit is why this is showing up now, both Plone 3 and CacheSetup are in maintenance mode, nothing big has changed in Plone 3 for the last 10 months. Our best guess is that most installed Plone 3 sites already have an older portal_cache_settings folder which is untouched upon upgrading or activating and everybody is playing with Plone 4.

Note: CacheSetup is not to be used with Plone 4, there’s  plone.app.caching and friends for that.
