I was doing some external method work on our production server (silly boy) and something went very wrong. Every time I start zope it will crash. This is both as an NT service and using ZHTTPServer. ZHTTPServer gives a stack dump that mentions initializing products and factories and stuff (unfortunatly my office has a power outage currently so I can't the dump or the data.bbb until 5 hours or so). Using the bbb.py it reports no corruptions so I can only presume the database contains some configurations that screws up zope. To make matters worse our expensive backup solution doesn't seem to have backed up data.bbb. What I need to know are a) What the likely causes of a something like I'm describing? I realize I havn't given much to go on, but ANY information you can give me at this point would very very appreciated. b) What tools do I need to modify the data.bbb. I can convert it xml ok but it seems there's no way to convert it back. Is there any tool where I can just roll back the last few transactions? (This may not work actually as it was probably the external method that did the damage). In case its relevent I guess I should include some detail of the external method I was working on. It was a method to determine if a user had permission to view an object. It looked at a users roles and the roles for the view permission. It would recurse with the parent if the object aquired roles. Thanks in advance for any ideas anyone has. Dylan. djay@lucent.com
