Hi, a while ago I realized that I liked the initial opening of network ports immediately on server start.
After working on a busy site with ZEO in the summer I wished that this feature would be configurable. There are different scenarios that ask for opening the network ports early or late: Situation 1: You are a developer and restart your server frequently. You want the ports to be open as soon as possible, even if the site takes a while to load, because your browser accepts a reload immediately. If you use tabbed browsing this also notifies you when the server is ready and you can read /. while waiting ... Situation 2: You are have a site with only a single application server (w/ or w/o ZEO) and have to restart your server. You want to minimize proxy errors (via Apache) and connection losses experienced by people visiting your site/using your application. So opening the ports early is good here. Situation 3: You are have a site that uses a ZEO cluster. You have to restart the application servers while people are using the site. As you have a load balancer, there are always some application servers around that can answer the queries. Now you want to open the network ports as late as possible. In the ideal case, when the complete server is ready. This avoids that people's connections go onto a still booting server and have to wait for several seconds which results in a even more loaded queue on the booting server ... Does this sound reasonable to make the behaviour of opening the ports configurable? Does anybody have an idea how hard this would be to do?
