Synchronization modifies "bobobase_modification_time" on the target. A safe method to check whether you have a current state is to register the "bobobase_modification_time" (on source and target) that resulted from the synchronization. A resynchronization is necessary when the "bobobase_modification_time" moved away from the registered "sync_bobobase_time"s. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

These are limitations of comparing objects that have only a bobobase_modification_time timestamp. See ZSyncer/README.txt, in the "Usage" section. Solving this problem is hard. See ZSyncer/TODO.txt. > We are using Zope 2.8.0 on the clients (Windows) > and Zope 2.8.4 on the server (Linux), could this be the problem? I have no experience running clients and server on different platforms, but I doubt that is the issue. Do the system clocks on client and server agree? It's best if they are as close as you can make them. You might also try adjusting the "fudge_secs" value in ZSyncer/Config.py. Read the comment describing its purpose. -- Paul Winkler http://www.slinkp.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] ANN: ZSyncer 0.7.1-beta1 released
Hi, we just installed Zsyncer 0.7.1-beta1 on a couple of our servers and have run into some problems with page template synchronization. Some items that have different time stamps on the server and on the development machines show on th sync screen as synchronized even when they are different. Then if we do a 'get' from the client, it fetches the file but the objects now appear as unsynchronized! We are using Zope 2.8.0 on the clients (Windows) and Zope 2.8.4 on the server (Linux), could this be the problem? Thanks a lot.
