Problems in the caffeinecirculationsystem

This post belongs also to the "lessons learned" category. With Plone 3, ZEO and supervisor combination you've probably configured your supervisor to start plone instances by running $BUILDOUT/parts/client1/bin/runzope. Problem is that with Plone 4 your $BUILDOUT/parts/client folder doesn't contain anything else than etc folder. You know starting instances by targeting supervisor to use $BUILDOUT/bin/client1 fg doesn't work like you'd expect (supervisor would control the client1 script - not the actual plone process). My colleague Jussi Talaskivi figured that using 'console' argument instead of 'fg' for bin/client1 script should do the trick. With 'console' argument stopping, starting and restarting Plone 4 instances with supervisor works like a charm. Below is full example of working supervisor configuration. [buildout] parts = supervisor [supervisor] recipe = collective.recipe.supervisor port = 8200 user = xxxx password =

This is reminder for myself and hopefully for other people too so that they don't have to waste several hours of valuable time looking for this simple piece of information. If you have experience setting up Plone 3 with ZEO and tempstorage (so that your sessions won't disappear in the middle of hardcore content managing) you might have trouble setting up same kind of setup while using Plone 4. Thanks to David Glick who enlightened   me that plone.recipe.zeoserver doesn't include whole Zope 2 in it's Python environment anymore. In this specific scenario this means that even though you have tempstorage in your eggs folder it isn't included in pythonpath when zeoserver part is being processed and this leads to below error message: Error: could not load package tempstorage: No module named tempstorage Package name: 'tempstorage' File name: 'component.xml' Package path: None For help, use bin/zeo-server -h Solution to this is to add this simp
