Is there an easy way for a python object to know when a web
request has completed?
For example, if I have an object that needs to do some setup and
tidy up around operations, I want to group operations together if
possible, but I don't want to delay the tidy up until the object is
thrown out of the cache.
I have tried using the mixin class Shared.DC.ZRDB.TM and defining
_abort, _finish, but without much success. The first time I call
_register the _finish method is called as I expected, but the
transaction forces a commit, which writes the object to the ZODB
with _registered set to 1 so that subsequent attempts to start a
transaction fail. Besides, this forces a transaction on the ZODB
which I would really rather avoid.
