BTree keeps some deleted objects referenced

I suspect a bug in the logic to remove objects from the BTrees.

Can you recreate this with a simpler test case? (I understsnd probably not given the time that's passes.)

[Adam Groszer (agroszer)]

ummmm, I'll try to add some tests

[Adam Groszer (agroszer)]

Was not that hard:

svn://svn.zope.org/repos/main/ZODB/branches/adamg-btree-keeps-reference

r103237

Seems like this happens when the object is in the key of the BTree.

Ah. That makes sense. I hate messing with the BTree C code this late
in the release cycle, but I'll see how hard this would be to fix.

Well, it was hard, but it's done.

Thanks for coming up with a test case.

With *much* resulting pain. But yeah, it's fixed. The fix is even
fixed and released.

Yup, but the fix was in the 'zodb' project (this one wasn't ever really
a Zope3 bug).

Marking anything "Fix Released" on the 'Zope3' projxect is actually a
bit suspect, unless the fix was actually part of one of the monolithic
tarballs.
