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. -- Duncan Booth duncan@dales.rmplc.co.uk int month(char *p){return(124864/((p[0]+p[1]-p[2]&0x1f)+1)%12)["\5\x8\3" "\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure? http://dales.rmplc.co.uk/Duncan
