OT: It would save lots of time if we had 2 things for the CF app: 1. Emails that go to appropriate people when status changes. e.g. when someone sets "Waiting for Author" the author gets an email so they know the reviewer is expecting something. No knowing that wastes lots of days, so if we want to do this in less days that seems like a great place to start. 2. Something that automatically tests patches. If you submit a patch we run up a blank VM and run patch applies on all patches. As soon as we get a fail, an email goes to patch author. That way authors know as soon as a recent commit invalidates something. Those things have wasted time for me in the past, so they're opportunities to improve the process, not must haves. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
