On: Tornado on Twisted

[frognibble]

It's not obvious to me that this is a win for Tornado users.

There's a cost to adding a dependency on Twisted. It's one more thing to download. There's more code to understand when something goes wrong. And so on.

What are the benefits to me as a web programmer? If I understand correctly, my application will work as it did before. If that's true, then Twisted did not add any win for me.

That's a very negative way to look at it.

The benefits you get are seamless integration with all the other twisted tools and a solid foundation under the relatively new Tornado stack.

And a bug in twisted will raise many more eyebrows than a bug in Tornado - hence they are more likely to be discovered by someone else before you.

No it is not, he stated that overall he removed 1200+ SLOC.

And added a 150,000-line dependency.

Which has better test coverage and more users than the Tornado stack. Honestly code quality would be the least of my concerns with twisted. If there's a python project where the critical parts can be labeled "mature" then twisted is it.

I criticize twisted for usability and documentation problems. But as the underpinning for something else (with hopefully better usability) it seems perfectly adequate.
