unicorn 4.8.0 - big internal changes, but compatible
This release contains fairly major internal workings of master-to-worker notifications. The master process no longer sends signals to workers for most tasks. This works around some compatibility issues with some versions of the "pg" gem (and potentially any other code which may not handle EINTR properly). One extra benefit is it also helps stray workers notice a rare, unexpected master death more easily. Workers continue to (and will always) accept existing signals for compatibility with tools/scripts which may signal workers. PID file are always written early (even on upgrade) again to avoid breaking strange monitoring setups which use PID files. Keep in mind we have always discouraged monitoring based on PID files as they are fragile. We now avoid bubbling IOError to the Rack app on premature client disconnects when streaming the input body. This is usually not a problem with nginx, but may be on some LAN setups without nginx). Thanks to Sam Saffron, Jimmy Soho, Rodrigo Rosenfeld Rosas, Michael Fischer, and Andrew Hobson for their help with this release. Note: the unicorn mailing list will be moved/changed soon due to the RubyForge shutdown. unicorn will always rely only on Free Software. There will never be any sign-up requirements nor terms-of-service to agree to when communicating with us.
