[Zope-CMF] HCFileStorage

[Glenn Pierce]

Hi 

Can anyone help me in setting up HCFileStorage

I have placed HCFileStorage in the ZODB directory with FileStorage

I have also created a custom_zodb.py with the following contents in my
INSTANCE_HOME


import Globals
import ZODB.HCFileStorage
                                                                                                                    
classes = ('WebPage',)
historyCategories = (('Content with History', classes, 10),)
storage = ZODB.HCFileStorage.HCFileStorage(Globals.BobobaseName,
historyCategories)
                                                                                                                 
DB = ZODB.DB(storage)

(WebPage is basically a Document with OFS.History)

After starting zope for the first time every thing appears to work
however when packing zope's db
I get permission errors of

Traceback (innermost last):
  File /usr/lib/zope/lib/python/ZODB/DB.py, line 499, in pack
  File /usr/lib/zope/lib/python/ZODB/HCFileStorage.py, line 534, in pack
    (Object: /var/lib/zope/instance/default/var/Data.fs)

_oriPack
    (Object: /var/lib/zope/instance/default/var/Data.fs)
IOError: [Errno 13] Permission denied:
'/var/lib/zope/instance/default/var/Data.fs'


Afer changing permissions on the Dat.fs which I know is no solution
(Just wanted to see if it would solve things)

I get
2003-07-28T15:27:18 ERROR(200) ZODB Couldn't load state for
'\x00\x00\x00\x00\x00\x00\x003'
Traceback (innermost last):

    (Object: /var/lib/zope/instance/default/var/Data.fs)
ValueError: I/O operation on closed file


I have no doubt that I am using HCFileStorage incorrectly as I can find
no examples.

Any help greatly appreciated.

Thank you
