Overview

---

TODO. This is an unfinished bug fix. This case was originally reported by Dan Aquino. If you throw a Ruby exception in a post_init handler, it gets rethrown as a confusing reactor exception. The problem is in eventmachine.rb, which calls post_init within the private initialize method of the EM::Connection class. This happens in both the EM::connect method and in the code that responds to connection-accepted events. What happens is that we instantiate the new connection object, which calls initialize, and then after initialize returns, we stick the new connection object into EM’s @conns hashtable. But the problem is that Connection::initialize calls #post_init before it returns, and this may be user-written code that may throw an uncaught Ruby exception. If that happens, the reactor will abort, and it will then try to run down open connections. Because @conns never got a chance to properly reflect the new connection (because initialize never returned), we throw a ConnectionNotBound error (eventmachine.rb line 1080). When the bug is fixed, activate this test case.
