With CacheFu not installed or not enabled, no problem. Therefore I suspect this *might* be a problem with CacheFu.

Plone 3.0.5, CacheFu from SVN.
Steps to reproduce:
I can reproduce. I can't provide a recipe to reproduce.

I would be happy to help debug. Just give me a bit of guidance.

I can't reproduce this. Thank you, anonymous, for offering to help debug... but you will need to log in and post another response before we can start as I don't know how to contact you.

Added by David Byers on Apr 04, 2008 05:50 AM
I forgot to log in? Silly me.

I have debugged a little further. The problem appears only with some of my custom views that contain non-ascii characters. They work without CacheFu though. In PT_pt_render, there is a code path where CacheFu renders the page, and I assume that is done differently in CacheFu than in Zope/CMF. I haven't been able to figure out how to change my views to avoid the problem.

It's hard to say if this is a bug in CacheFu or a bug in my views, but if it is the latter, then CacheFu still behaves sufficiently differently from stock Plone that it exposes problems that would otherwise be hidden, and I don't think that's a particularly good thing.

David, can you try applying the fix in...

http://dev.plone.org/collective/changeset/63107

and let me know if it fixes this issue for you?

Added by Stefan H. Holek on May 09, 2008 04:14 PM
I can confirm this happening in Plone 3.0.6 + CacheSetup 1.2 with a ViewPageTemplateFile in UTF-8 format containing non-ascii characters. For me it happens in line 153 and the traceback is a lot shorter. :-)

We have found a similar problem after enabling CacheSetup on our Plone site at http://deerparkmonastery.org.

Our setup:
    * Plone 3.1.3
    * CMF 2.1.1
    * Zope (Zope 2.10.6-final, python 2.4.5, linux2)
    * Python 2.4.5 (#1, Jul 25 2008, 23:09:10) [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)]
    * PIL 1.1.6

As soon as we enable CacheSetup in the configuration page, we cannot access our site except through the ZMI, and the following error comes up:

Site Error

An error was encountered while publishing this resource.

UnicodeDecodeError
Sorry, a site error occurred.

I had the same problem with a copy sign in the footer. (version 1.2 of cachefu)

Can someone give some more info about this? If the patch linked above still valid?

This is a very bad bug for non english users! If we can help in debugging we are here!

Hi Luca,

the issue is still valid with the patch, linked above. This is the error message:

Hi again Luca,

I have a quick and dirty solution for this Problem. I just used the FasterStrionIO out of Products.CMFPlone.patches.unicodehacks instead of the standard StringIO. FasterStringIO catches the exception and decodes the string in utf-8.

But I'm really not happy with this solution. Because the "wrong" data will be appended by the TALInterpreter :-(

Please have a look at the appended patch file and let me know what you think about it.

Thanks so far, chris
Added by Christoph Glaubitz on Nov 13, 2008 04:07 PM
Ok. One step back. In my case there was an german special character (not html-decoded) in a template.
TALInterpreter just read in a string, and mixes it with the utf-8 StringIO in patch_cmf.py. Without a special char, no error occures. However, in fact it was a defect in a self made template.

So... There is no defect in CacheFu. The implementation without the patch (http://dev.plone.org/collective/changeset/63107) should mostly work. Even, if there is no template, containing a character what is over ascii. The change to utf-8 does not solve the issue, because TALInterpreter still just read strings.

In my opinion, it would be great to see FasterStringIO in patch_cmf.py, because it's not easy to associate the error message with this marginal failure in the template.

Thank you for replying!

In any case we fixed the problem replacing the non ascii char with the HTML entity.

In the past I got some problem with using tal:content with unicode strings. For what I remember using tal:content="string:unicodevalue" raise errors. But using tal:content="python:unuicodevalue" works!

My only problem is that often we (or power users customer) build template with italian (non ascii) characters and in those cases we can rely directly on CacheFU is there is the possibility that enable this brakes the site!
