Re: [Zope-dev] Zope2.7.0rc2 AttributeError: 'NoneType' object has no attribute 'setHeader' - SOLUTION
Hi all, You'll have seen my message earlier in the month about the above. Well, we figured it out. To cut a long story short, we had a role called 'SYS' in the folder. It was a real forehead slapping moment, with all the team looking around at each other with the unsaid thought of 'oops, that's *probably* not a good idea'. This was the same day that someone else in the team found out that using 'yield' as a variable is also not a good idea. So, we deleted the role, and Bob's your uncle. Lots of smiles all around. cheers for all the help, Tone. -- Dr Tony McDonald, Asst Director, FMSC. 0191 246 4543 Project Manager, FDTL-4 ePortfolios http://www.eportfolios.ac.uk/ ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

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).

"REQUEST.RESPONSE" is set up in
"ZServer.HTTPServer.zhttp_handler.continue_request".
It should be impossible that is is "None".
Maybe, we have a memory corruption.
I have seen objects magically becoming "None" in
Python versions with memory corruption problems (Python 2.1.1).

[Zope-dev] Zope2.7.0rc2 AttributeError: 'NoneType' object has no attribute 'setHeader'
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 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 , 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. -- Dr Tony McDonald, Asst Director, FMSC. 0191 245 4223 Project Manager, FDTL-4 ePortfolios http://www.eportfolios.ac.uk/ ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
