Ok. :-)

Continuing with the ZODB.POSException.Conflit...

Now I know the problem with Zeo on NT is with the ClientStorage and not with the ServerStorage. You ask why? Because Ive tested different setup to come to this conclusion.

ZSS - Zeo Storage Server ZCS - Zeo Client Storage

1- First setup:

Machine 1: Running ZSS on NT Machine 2: Runninc ZCS on NT Machine 3: Running ZCS on NT

Conclusion: with this setup clients ARE NOT able to view/write changes to objects changed by other clients.

2- Second Setup:

Machine 1: Running ZSS on Linux Machine 2: Runninc ZCS on NT Machine 3: Running ZCS on NT

Conclusion: with this setup clients ARE NOT able to view/write changes to objects changed by other clients.

3- third Setup:

Machine 1: Running ZSS on NT Machine 2: Runninc ZCS on Linux Machine 3: Running ZCS on Linux

Conclusion: with this setup clients ARE able to view/write changes to objects changed by other clients.

4- Fourth Setup:

Machine 1: Running ZSS on NT Machine 2: Runninc ZCS on Linux Machine 3: Running ZCS on Linux Machine 4: Running ZCS on NT Machine 5: Running ZCS on NT

Conclusion: with this setup ALL LINUX clients ARE able to view/write changes to objects changed by other clients. All NT clients ARE NOT able to view/write objects changed by other clients.

NT clients can view/write objects that have never been changed. But cant viewchanges/change objects changed by other clients. However linux clients can viewchanges/change objects changed by other NT and Linux clients.

So my conclusion is that there is a problem with Zeo Clients on NT. And I guess is related with the invalidator, the NT clients cant see changes others do to objects, or something is just a guess. I'm using cPickle.pyd which is cPickle.so on Linux. Maybe there is a diference with this shared object from Linux to Nt.

I'm using the win32 version of Zope2.2.0b1, and ZEO-0.2.

Ok, ./dig_resume

Hi,

I can see now that the problem is not per Data.fs but per object. The problem isnt that 2nd Client to run cant write do Data.fs, I found that its a per object conflict and not Data.fs, both clients can write to the ZSS but once client B writes to object X, Client A will never see the changes neither change the object X, but is capable of changing other objects.

Objects changed buy Client B become "locked" for client A and viceversa.

Anyone testing ZEO? Best Regards, Júlio Dinis Silva ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
