[Zope] Re: Problems using fsrecover.py from 2.5.1 with 2.4.3?

[Julián Muñoz]

Jean,

I am intested, because I was just planning to use fsrecover.py taking
it from 2.5.1 and putting it into 2.4.3 (the same as you). I have copied
fsrecover.py (2.5.1) to fsrecover2.py in 2.4.3.

Well, it seems to work, and a "top programmer" (in zope-dev mail-list)
told me that it should work.

So, do you think the problems comes from an incompatilibility of
fsrecover.py with Zope 2.4.3, or is because your database was really
damaged and fsrecover has done the "well" the work  ??


Thanks !!

Julián

Hi all I'm attempting to diagnose a Data.fs that might be wonky. I'm
sending a record of my attempt to the list in the hope that
other people are better at interpreting the results than I am. It was
written by this Zope:  $ cat ./lib/python/version.txt
 Zope 2.4.3 (binary release, python 2.1, linux2-x86) The fsrecover.py I'm
using comes from:  Zope 2.5.1b1 (source release, python 2.1, linux2) I get

After:  103887195 May  1 14:39 Data.fs.fsrecover I can start a Zope on the
"recovered" Data.fs without problems,
and access it through a browser. It works fine, until I try
to access certain ZClasses stored on Racks (eg. 'License'
instances raise KeyErrors, 'Customer' instances are fine). Then
I get KeyErrors, with this in the log: ------
