Tackling Thread Safety in Python

Abstract

Thread safety is often overlooked when we start with Python for developing simple scripts. But the hidden monster will be unleashed when we try to run non-thread safe code in a multithreaded setup.

We will discuss the problems which can happen when seemingly good code is run in a multithreaded environment. We will walk over the concept of race coditions, how Python’s GIL currently affects multithreading and will cover steps to fix thread unsafe code using synchronization primitives.
