[Zope-dev] plone.org - chrism_installer_branch
Hi. just wanted to drop you guys a line and say that chrism_installer_branch will save the world. But I have some questions: Chris said its based on HEAD. Whats the difference between HEAD and Zope-2_6-branch? I probably shouldnt be running HEAD in production? I am having severe leakage here are some refoucnts: DateTime - 62263 IOBucket - 32641 PloneFolder - 22766 User - 22196 PersistentMapping - 12846 CMFDefault.Document.Document - 12820 I have have the python security machinery turned on. should I move to Zope2.6 branch instead of trying to fight? what would I look at next? ~runyaga ___ 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 )

While fixes will be applied to both 2.6 and the head, 2.6 is the point where stability will be focused on. What it looks like to me btw is that your Documents are holding on to the root of the ZODB perhaps -- do you do anything that would cause that to be stored? ___ 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] limit to number of operations in a transaction?
Christopher N.Deckard [EMAIL PROTECTED] writes: I have roughly 1,500 people in the database. I wrote a script to migrate the people. Basically it does getProperty for each property on each person folder, then creates the new person object which uses XML. Zope apparently cannot handle this number of operations in one transaction. Zope gets slower and slower and eventually becomes on responsive. It looks like the script has completed, but nothing is ever committed to the ZODB, and since Zope is unresponsive it must be restarted. This, as expected, kills that entire transaction which was never committed. Is it known that large numbers of operations, such as above, in a single transaction can cause problems? A transaction, of course, being a request, and an operation being something like manage_addProduct. In practice I've only seen problems when I'm dealing with lots of data and need to be thinking about this anyway :) I've solved the problem by using xmlrpc and for person in people calling my migrate_person script for only one person at a time. This is SO MUCH FASTER. I previously ran the script that migrates all of the people, and after 8 hours it still had not completed. As Jens replied, this is because the transactions are getting committed for each person, and you can do this without xmlrpc by committing in your script. The possible drawback of committing after each person is that you're committing a new version of the object being modified. Depending on how you're storing the stuff this can grow your ZODB - if every person is a node in a single ParsedXML document, you'd be storing 1500 versions, each one person bigger than the last. You can use transactions and subtransactions to juggle database size, memory usage, and temp file usage. -- Karl Anderson [EMAIL PROTECTED] http://www.monkey.org/~kra/ ___ 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 )

Alan, You mentioned that you thought the chrism-install-branch was slow... do you see the slowness and the leakage when using the tip of the 2.6 branch? - C alan runyan wrote: Hi. just wanted to drop you guys a line and say that chrism_installer_branch will save the world.

i dont believe so.. its plone.org thats doomed.
