Agreed.

Maybe, we have a memory corruption.

Could be memory perhaps, but this is python2.3.3.

The problem I'm having is that these are all stock Zope products from a 
Zope2.7.0rc2 release. The traceback is coming from the Zope core.

Traceback (innermost last):
...
  Module Shared.DC.Scripts.Bindings, line 320, in
__render_with_namespace__
  Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec
  Module App.special_dtml, line 175, in _exec
  Module DocumentTemplate.DT_Util, line 201, in eval
   - __traceback_info__: RESPONSE
  Module string, line 0, in ?
AttributeError: 'NoneType' object has no attribute 'setHeader'
This also seems different from what Christian is reporting;

So, I'm still baffled by this.

Many thanks to all those providing more data points. I *think* this is 
a 'Zope' thing and not a 'Tone' thing, but I've been wrong in that area 
before ;)

cheers

 Looks like RESPONSE is None.

 I do not see how this can happen...


Exactly! - this is why I said I'd never seen this before.

It's a 2.6.1 Data.fs that's been dropped into a stock 2.7.0rc2 release 
and I get this error.

Whether or not RESPONSE is None should not be dependent on
the Data.fs (RESPONSE is recreated for each request and
is independent of persistent objects).

I have no idea why this is happening, so I was hoping that it was an 
artifact of the 2.7.0rc2 release itself.

 Probably, I would start debugging.


Quite likely, but I have *no* idea where to start with this. All the 
modules mentioned in the trackback are Zope supplied ones, not third 
party ones, so I'd assumed it might be the core software.

REQUEST.RESPONSE is set up in
ZServer.HTTPServer.zhttp_handler.continue_request.
It should be impossible that is is None.

[Zope-dev] Zope2.7.0rc2 AttributeError: 'NoneType' object has no attribute 'setHeader'

2004-02-05 Thread Tony McDonald
Hi all,
We're in the process of migrating our sites to 2.7, so to get the guys 
up to speed we picked a site at random today. Did the 
/usr/local/zope/bin/mkzopeinstance.py jig (works very well), copied the 
Data.fs, some external methods, a Zwiki product and were good to go. 
This is from a Zope-2.6.1 site.

We found out that LocalFS needed updating, so found a 2.7 compatible 
version and installed that.
http://www.my-zope.org/Members/kedai/LocalFS-1-1-0.tgz/file_view

Now we have a very peculiar error, that I'm not posting to the Zope 
list as it's the RC2 version of Zope2.7 that we're using.

We have an index_html (initially DTML document, then tried method) that 
can be created (located at /prototype/myporfolio/index_html), have it's 
security settings changed quite happily. Then when the object is called 
we get the error in the subject line. The system specs are;

 Zope Version (2.7.0rc2, python 2.3.3, sunos5)
 Python Version 2.3.3 (#3, Jan 23 2004, 13:36:43) [GCC 2.95.3 20010315 
(release)]
 System Platform sunos5
 SOFTWARE_HOME /usr/local/zope/lib/python
 ZOPE_HOME /usr/local/zope

and the traceback is;

Traceback (innermost last):
  Module ZPublisher.Publish, line 100, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 40, in call_object
  Module Shared.DC.Scripts.Bindings, line 306, in __call__
  Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec
  Module App.special_dtml, line 175, in _exec

  Module DocumentTemplate.DT_Util, line 201, in eval
   - __traceback_info__: RESPONSE
  Module string, line 0, in ?
AttributeError: 'NoneType' object has no attribute 'setHeader'

I have never seen anything like this from Zope before (been using it 
since 1.0.3 so I've seen it do quite a bit! :).

I've looked through the zope-dev archives and can't find anything 
related (unless it's got something to do with manage_page_charset not 
being callable? The only thing I could find on the collector was issue 
381, http://collector.zope.org/Zope/381 'HEAD request method broken' - 
but that doesn't seem relevant in this condition.

*Any* thoughts would be gratefully received. To recap, we took a pretty 
plain 2.6.1 site, loaded it into 2.7.0rc2 and get the traceback 
above...

cheers
tone.
