Re: django 1.1 performance versus django 1.2 performance

But what changed in 1.2 vs. 1.1 that caused cloning to become slower? Is it fixes for correctness that were missing? And if 1.3 is slower than 1.2, why the slow down there? If the slowness is for a good reason (correctness is about the only one I can think of that is really valid), then fine.

Re: Dynamically form modification - Is this possible?

There are two pieces to this. 1. The Django form. 2. Whatever comes back in your HTML form's POST. Your Django form will have zero or more fields in it. Your HTML form will POST back those fields (if any) and possibly new ones. Your Django form's __init__ will read the 'data' keyword

Interesting race condition in Django views with decorators (fix included)

So, here's an interesting race condition, which causes request bleeding to happen. If you use a decorator on a view method, where the decorator is a class, the class isn't created per request, it seems to stay the same throughout. So, if you define any logic within this class, which depends on
