[Zope3-checkins] CVS: Zope3/src/zodb/storage/tests - undo.py:1.14

[Jeremy Hylton]

Update of /cvs-repository/Zope3/src/zodb/storage/tests
In directory cvs.zope.org:/tmp/cvs-serv16613/src/zodb/storage/tests

Modified Files:
	undo.py 
Log Message:
Remove _p_serial from the PyPersist_HEAD.

Persistent objects still have an _p_serial attribute, but it is stored
in the instance dict for most objects.  If a specific class doesn't
have an instance dict, it must arrange to store _p_serial somewhere
else.  The BTrees store it in their object structs.

The change reduces the __basicsize__ of all persistent objects by 4
bytes, which saves 8 bytes in practice because of obmalloc rounding.

One consequence of this change is that objects don't have an _p_serial
== None at creation time.  Two tests depended on that.
