I noticed that Session has no method len. Wouldn't it be useful to add
one, like this:
--- orm/session.py 2007-07-06 14:38:22.000000000 +0200
+++ orm/session.py.orig 2007-07-06 14:43:48.000000000 +0200
@@ -642,6 +642,9 @@
def __iter__(self):
return iter(list(self.uow.new) +
self.uow.identity_map.values())
+ def __len__(self):
+ return len(self.uow.new) + len(self.uow.identity_map)
+
def _get(self, key):
return self.identity_map[key]
Then, one could flush() and clear() it if it grows too large.
(Generally, I think any class with __iter__ should have __len__ too.)
Best regards
