Olivier, a few remarks: 1) some other robust platforms (example Java servers) use to have a global budget for session memory. Once you reach that limit (no matter how you fill it), you get an ou of memory Exception. I think this is much more flexible and explicit. It's alright OpenERP to say it's better than that the Java platform, but in that case it just at least do an equivalent job or better. Not just implement it's own hacky memory limit and session garbage... Isn't there some robust standardized equivalent of Session management in Python? 2) at least an Exception should be raised when you reach the limit. Imagine you reach it while processing accounting data, currently you could miss half the records silently... Failing is OK, memory is limited anyway, but you should be warned. 3) if there is such a hard limit, at least it should go in the global configuration so it's explicit it's a parameter you can tweak to adapt your need, just like you could give more memory to some application for instance.
Thanks for re-opening that bug. For the record, here is the cross link to my original report where a large picking couldn't be processed: https://bugs.launchpad.net/openobject-addons/+bug/709559 I'll make my best to look at the perf aspect of it on my side.

I want to do a "pre" import of many csv lines into the osv.osv_memory object before validating in the wizard and do the actual import in an osv.osv object. i made a simple scenario to check if it was a bug : from osv import fields,osv class test_school(osv.osv_memory): def _do_import(self, cr, uid, ids, context={}): myself=self.browse(cr, uid, ids, context)[0] for i in range(0,myself.size): self.pool.get("test.person").create(cr, uid, { "name":"Doe", "age":i, "school_id":myself.id }) return True _name = "test.school" _columns = { "name":fields.char("name",size=20), "size":fields.integer("size"), "students":fields.one2many("test.person","school_id","students"), } test_school() class test_person(osv.osv_memory): _name = "test.person" _columns = { "name":fields.char("name",size=20), "age":fields.integer("age"), "school_id":fields.many2one("test.school","school",ondelete="cascade"), } test_person() This is a silly example but you can make tests with size over 211 : the number of lines will remains 211 (sometimes 201...) and only the last added lines will remain in the table... _______________________________________________ Mailing list: https://launchpad.net/~c2c-oerpscenario Post to : [email protected] Unsubscribe : https://launchpad.net/~c2c-oerpscenario More help : https://help.launchpad.net/ListHelp
