Plone 4, ZEO and tempstorage

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 simple oneliner to your buildout.cfg zeoserver part:


[zeoserver]
...
eggs = tempstorage
...

    I thought this kind of trick was needed for Plone2.5 and earlier versions, but not for Plone3.

    Plone3 with plone.session doesn't use the Zope2-session-machinery and tempstorage? (except when your own code uses it explicitly)

    Almost no code in Plone 3 uses REQUEST.SESSION, and really no code in Plone 4 does.

    So you only need tempstorage if any custom code makes use of this.

    Hmm.. maybe my information about this specific topic is out of date (I wouldn't be surprised).

    I've thought that when you're using zeo with loadbalancing you'll need some way to keep logged in users session available regardless of which backend user ends up. I guess I'll try to dig some more information about this.

Usability and Plone

I've seen in here and there someone mentioning that usability of Plone is very good. Lot's of people - me included - like the fact that in Plone you don't have separate content management interface compared to some of Plones rivals. That counts for something when we're talking about good usability. Still that is only one quite small part of the whole picture. So what else is there? What do people like in Plone and where are the rough edges for end users? If general consensus is that Plone does have good usability, where is the actual proof of that? On plone.org I found one page in developer documentation mentioning following:  "Plone differentiates itself on usability. The intuitiveness of the user interface is what attracts people to Plone the most." I interpret this sentence meaning about the "one view for all" approach. What bugs me in this is that this whole sentence about good usability is about how the UI works compared to Plones competi...

Speed comparsions between Plone and Wordpress

Jon Stahl wrote recently a blogpost about Plone being three times faster than Dropal, Joomla and Wordpress . We had a small discussion about this in my workplace and as my colleague pointed out this wasn't a really that comprehensive test that you could state Plone being 3 times faster than it's competitors. This seemed a bit unfair test considering how fast this has been spread in tweet/blogosphere, so I decided to repeat the test with a bit more critical viewpoint. What's wrong in the original test? No one would consider opinion poll with 10 answers nowhere near trustworthy - it's all the same with requests. I didn't want to put up all the cms so I just set up second best (Wordpress 2.9.1) and compared that to my Plone development site (4.0a3). As a comparsion I did the first test with same ab command Jon used and my iMac gave following results: Wordpress: 7.13 requests / second Plone: 17.10 requests / second So far we have clear winner and Jons data hol...

Plone 4, ZEO and supervisor

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 = ...
