I've got a question for you on the removal of the LISTEN / NOTIFY stuff in the Postgresql adapter: it looks to me as though your code was not doing the async check-for-notifies as shown in the 'notify.py' in the psycopg2 examples: http://www.initd.org/tracker/psycopg/browser/psycopg2/trunk/examples/notify.py So, any notifies you got were only capture on the basis of "syncrhonous" activity (a cursor doing some other work). Could that explain the unreliability which caused you to remove it? The symptom would be like the time that the ZEO async stuff got dropped in Zope3 during the Twisted integration[1]: a "busy" client would stay up to date, but an idle one would serve stale objects from cache. > BTW, thanks again to Jarn for making this possible. Yay, Jarn.
