A “Leaks” Tool Tutorial

"WSGI middleware which displays sparklines of Python object counts and allows you to introspect them, using the gc module under the hood"

Finding and fixing memory leaks can be a real challenge, but luckily Python has some pretty good tools for spotting these things. I have already written about this issue and this post will go into more details on how to spot and debug a memory leak in MySQLdb, which is the standard Python wrapper for MySQL.

Despite what a lot of people believe, it's easy to introduce memory and resources leaks in .NET applications. The Garbage Collector, or GC for close friends, is not a magician who would completely relieve you from taking care of your memory and resources consumption. I'll explain in this article why memory leaks exist in .NET and how to avoid them. Don't worry, I won't focus here on the inner workings of the garbage collector and other advanced characteristics of memory and resources management in .NET. It's important to understand leaks and how to avoid them, especially since they are not the kind of things that is easy to detect automatically. Unit tests won't help here. And when your application crashes in production, you'll be in a rush looking for solutions. So, relax and take the time to learn more about this subject before it's too late.
