Failing at Failing: How and Why We've Been Moving Away From Exception Handling

所属分会场：Keynote

Exception handling became a mainstream concept when it was introduced into C++. With checked exceptions, Java pushed the experiment even further. But how well has exception handling really solved the problem it was intended for? No other language since Java has adopted checked exceptions, and some new languages like Go have avoided exceptions altogether, while languages like Erlang take a completely different approach to failure. In this presentation, I'll look at the history of error reporting, early attempts at error handling and recovery, the problems introduced by exception handling, the illusion that we can recover from errors, and how new and existing languages are decoupling themselves from exceptions and moving towards simply reporting errors.
