As in, I use Rails to develop web applications. In the past months, I've had to painstakingly go back to every single app I've ever worked on, and manually update it in whatever minor way it needed updating. Now, I'm going to do that again.
If you consider that I'm going to continue to build Rails applications, the number of apps I will have to update every time a security vulnerability comes out will be larger and larger. For a framework that prides itself on sane defaults, it doesn't seem quite sane to have to worry about taking down, updating, and then relaunching every app you ever had when one of these vulnerabilities come out.
I don't mean updating a Rails 2.3 app to 3.2 automatically, just applying these security patches automatically, or prompting the user to do so. Our operating systems do it, our IDEs do it, our programs do it, why can't a framework? I'm not saying it would be easy, but I'm sick of having to be subscribed to these email groups just to start the manual process of fixing everything.
