[Zope-dev] Data.fs ZEO

2001-07-03 Thread Priya Ramkumar

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

[Zope-dev] Data.fs lost?? ideas?

2001-06-29 Thread Chris Keyes

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??

Cheers Chris Keyes
 Andy Dawkins

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

.except during an 'Undo', when one byte is rewritten in the middle
of the file.

  My Questions are: is there a way to delete the last transaction from
  Data.fs,
There is a product "tranalyze" (or "tranalyzer", "tranalyse", "tranalyser")
that allows you to analyse and fix your Data.fs.

Zope 2.2 contains an "ZODB.fsrecover" which is able to fix a
corrupted "Data.fs".
  and can i backup the Data.fs when Zope is running. 
Yes. Just copy it.

One answer: use tranalyzer to find the offset of the start of the
last transaction and truncate the file there.

 Data.fs, and can i backup the Data.fs when Zope is running. Is the

Yes.

 backup of Data.fs inconsitent when i make the backup at the same time a
 user writes to it?

No.  If the last transaction in Data.fs s incomplete, Zope will ignore it on
startup.

Re: [Zope-dev] Data.fs corruption (reproducable)

2000-05-29 Thread Dr. Peer Griebel

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.
