Re: [Zope-dev] ZEO on NT? update
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.

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, JĂșlio Dinis Silva ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

(snip) This is very helpful. Our *current* focus is on Unix. I've seen this problem on Windows, but haven't had time yet to look into it, and probably won't very soon. I certainly haven't done the sort of test you've done. I don't think that the problem it pickle-related, since pickles are platform independent. It appears to be some strangosity with the async/networking code. Let me know if you figure anything out. :) Jim -- Jim Fulton mailto:jim@digicool.com Python Powered!

ISTR the announcement or the ZEO page say to use zope-dev. Has that changed?
