[Zope3-checkins] CVS: Zope3/src/zodb/btrees - BTreeTemplate.c:1.11

[Tim Peters]

Update of /cvs-repository/Zope3/src/zodb/btrees
In directory cvs.zope.org:/tmp/cvs-serv1336/src/zodb/btrees

Modified Files:
	BTreeTemplate.c 
Log Message:
BTree_newBucket():  This leaked a reference to the bucket-construction
function (like OOBucket).  The patch fixes 1 leaking reference per
iteration of a test program I have, leaving about 108 leaking refs per
iteration.  So far, I haven't even been able to figure out what kinds
of objects are the leak beneficiaries, except to note that they're
probably static type objects (like OOBucket) since in a Python debug-build
the leaks do reflect in sys.gettotalrefcount() but not in the sum of
sys.getrefcount(x) across all x in sys.getobjects(0) (and, AFAIK, only
static type objects don't show up in the sys.getobjects(0) list).
