[Zope-dev] Data.fs & ZEO
Hi I have installed Zope version 2.3.3 & ZEO1.0. I would like to copy the Data.fs from my previous zope installation which is 2.2.4 to the new one. I copied the Data.fs, Data.fs.lock, Data.fs.tmp & Data.fs.old from the old Zope to the "var" directory in the "Instance_home" directory. I start Zope from the "Instance_home" by invoking "zctl.py". After I copied the Data.fs files to the new Zope, I get the following error. File /export/usr/local/Zope3/Zope_software_home/lib/python/ZEO/ClientCache.py, l ine 325, in update File /export/usr/local/Zope3/Zope_software_home/lib/python/ZEO/ClientCache.py, l ine 401, in _store TypeError: __add__ nor __radd__ defined for these operands -- 2001-07-04T04:01:45 INFO(0) ZEO Server Close 136753056 -- 2001-07-04T04:01:45 PROBLEM(100) zdaemon zdaemon: Wed Jul 4 06:01:45 2001: The ki d, 75464, died on me.

[Zope-dev] Data.fs lost?? ideas?
In an attempt to upgrade the Zope from 2.3.1b1 to 2.3.2 we encountered a problem. All the data in out Data.fs file was lost so it had to be restored from a backup. Any ideas as to what the problem may have been??? Procedure Stopped the Zope instance Changed the Zope instance home and port Restarted Came back to prompt quickly Logs were empty when checked Enabled Debug Restarted Logs show Data.fs is locked Made sure Zope was stopped Killed the process that had the file locked (kill -9) Restart Realised file was 1.6meg not 700 Ideas guys??

An incomplete transaction at the end of Data.fs gets ignored and is subsequently overwritten by the next new transaction.

No. If the last transaction in Data.fs s incomplete, Zope will ignore it on startup. --RDM ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] Data.fs
Hi, I'am using Zope 2.1.6 and my Data.fs is going corrupted and i don't have found a way for backup this file. My Questions are: is there a way to delete the last transaction from Data.fs, and can i backup the Data.fs when Zope is running. Is the backup of Data.fs inconsitent when i make the backup at the same time a user writes to it? I want to a backup Data.fs twice a day. so i want to have 14 data.fs files every week. On this way i can find out when the error occurs and i can restore an older version of Data.fs. as ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] Data.fs corruption (reproducable)
FYI: I managed to solve the problem. I simply took the third parameter out of the parameter list and initialized the variable inside the function: def FormatPreis( v, n=2, thou=regex.compile( "\([0-9]\)\([0-9][0-9][0-9]\([,.]\|$\)\)").search) becomes def FormatPreis( v, n=2 ) The new code is a little bit less efficient. But this doesn't hurt us.
