I've just checked in a refactoring of the event loop to squid-3. This is mostly harmless. It will likely have one negative impact though: the selftest for EventLoop() will fail if the comms module being built is not updated to the new protocol because the comms code has a now-inappropriate assert in it.
The change to comm_select is that when there are: - no fds - squid is not shutting down comm_select should now return COMM_IDLE rather than fataling. I've updated comm_poll, but due to time constraints and our current only-build-one-loop approach I haven't updated epoll/select/kqueue. I hope to get some hack time next weekend, when I'll transition the event checking logic in the event loop to be comms-loop independent - I ran out of time on Sunday, and this is strictly weekend-stuff for me. When this transition is done, the improved event loop I sketched out a while back will be in place, allowing for relatively easy testing of event loop dependent code - such as the http pipeline, or icap etc etc. Hope this is of use, Cheers, Rob -- GPG key available at: <http://www.robertcollins.net/keys.txt>.
