No, they don't. Patches accepted <0.5 wink>. There are many ways to get in trouble with BTrees (mixing key types is just one), and the ZODB Programming Guide has pages of discussion of potential pitfalls (including mixing key types) already: http://www.zope.org/Wikis/ZODB/FrontPage/guide/node6.html (and a copy of that in PDF format is shipped in every ZODB release). I don't think mixing key types is, e.g., more important than the other ways to create an insane BTree, and I don't think pages of discussion fit sanely in interface docstrings either. This is something that belongs in documentation. Since it already is covered in the only "official" ZODB docs, I'm not inclined to do more than that. _______________________________________________ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
