[Zope-dev] More Transience weirdness in 2.7.1b1

[Steve Jibson]

It seems that there may still be some strangeness with Transience. 
We're running Zope-2.7.1b1 (Python 2.3.3, Fedora Core 1) and after using 
the system for a day or two, it got the following error on a page that 
accesses the SESSION:

  Traceback (innermost last):
    Module ZPublisher.Publish, line 101, in publish
    Module ZPublisher.mapply, line 88, in mapply
    Module ZPublisher.Publish, line 39, in call_object
    Module OFS.DTMLDocument, line 128, in __call__
     - <DTMLDocument instance at 9e684350>
     -URL: http://george/login/root/ChooseAccount/chooseAccount/manage_main
     - Physical Path: /login/root/ChooseAccount/chooseAccount
    Module DocumentTemplate.DT_String, line 474, in __call__
    Module DocumentTemplate.DT_With, line 76, in render
    Module DocumentTemplate.DT_In, line 703, in renderwob
    Module DocumentTemplate.DT_Let, line 76, in render
    Module DocumentTemplate.DT_Util, line 198, in eval
     - __traceback_info__: value
    Module <string>, line 1, in <expression>
  NameError: name 'SESSION' is not defined
It doesn't appear to be a problem accessing a variable in the SESSION, 
but finding "SESSION" itself.

So, I hook-up to the ZMI and click on *temp_folder*, then click on      
*session_data (Session Data Container)* and I get the following error:
  Traceback (innermost last):
    Module ZPublisher.Publish, line 101, in publish
    Module ZPublisher.mapply, line 88, in mapply
    Module ZPublisher.Publish, line 39, in call_object
    Module App.special_dtml, line 62, in __call__
    Module DocumentTemplate.DT_String, line 474, in __call__
    Module Products.Transience.Transience, line 709, in nudge
    Module Products.Transience.Transience, line 555, in _gc
  RuntimeError: the bucket being iterated changed size
The same thing happened yesterday and re-starting Zope seemed to get 
things working again.  After the problem yesterday, I changed my temp 
database to use filestorage to see if that would help.  No luck, the 
problem showed up again today.

I have not restarted Zope again today, so my system is still in the 
"screwed-up" state.  Chris, if you'd like, I can probably get you access 
to the system if there is anything to be learned from it in its current 
state.

Thanks,
Steve
