[Ron Wills] > Ok, I'll simplify. > ... Ron, can you supply a self-contained test program, demonstrating the problem, that other people can run? There are many errors in the "well, it's kind of _like_ this" snippets you're giving us, to the point that I can't guess what may be important.
For example, > del __len__(self): You didn't run the code you pasted there, since "del" should be "def". Then > db = DB(filestore) > conn = DB.open(db) couldn't have worked either; you probably intended conn = db.open() instead. The next line can't work either: > conn.root['SomeClass'] = OORTable(SomeClass) conn.root() was intended. Fix that, and it still blows up, because your OORTable.__init__ referenced a variable that doesn't exist. That's not the last of the problems, and, in the end, as Victor noted the code didn't commit the transaction, so there was no reason to _expect_ the changes to persist. When I repaired that too, I ended up with a pair of programs that didn't show any problem -- each time I run them, my print len(ootable) prints 0 to the console. > ... > Why this is happening or to give consistent testing for the failure > is beyond me, and unfortunately I cannot freely share the code as > this is a contracted commercial product :(. I appreciate that, and don't really want all your code anyway ;-) What I want is a minimal, self-contained failing example we can actually run as-is. You also said: > all other methods of the class are for our query engine and importing > routines from a third party sql db. This is not the source of the > problem and can be removed. and that's what would help: remove _everything_ that's irrelevant to the problem, and share what's left (I assume here that the proprietary part of your code is in the query engine, and you say that's not relevant to the problem, so it should be able to create a failing example that doesn't use that part). _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
