Issue #7839 has been reported by tenderlovemaking (Aaron Patterson). ---------------------------------------- Feature #7839: Symbol.freeze_symbols https://bugs.ruby-lang.org/issues/7839 Author: tenderlovemaking (Aaron Patterson) Status: Open Priority: Normal Assignee: Category: Target version: Hi, On team Rails, we're having troubles with Symbol creation DoS attacks. From our perspective, there should be a point in the application where symbols should stabilize, meaning we don't expect the number of symbols to increase while the process is running. I'd like to be able to call a method like `Symbol.freeze_symbols` which would essentially freeze the symbol hash, such that if any new symbols are created, an exception would be thrown. I can work on a patch for this, but I wanted to throw the idea out there. -- http://bugs.ruby-lang.org/
