The latest ipython branch doesn't work in Chrome

[certik]

It works great in Firefox. I don't have time currently to debug this, but in Chrome, it doesn't show any cells if I create a new notebook. My ipython master is a3c02d8.

What version of Chrome and Tornado are you using? Unfortunately, a few days ago in their dev channel, chrome changed their websocket protocol identifier and broke with released tornado. Major PITA for us...

[minrk]

Yes, and tornado master has been updated to work.

We really need to draw a message on the error (426) that unsupported websockets causes.

[fperez]

Marking for 0.12 so at least we provide a meaningful error instead of the blank stare of death :)

[certik]

I use the latest tornado, and Chrome 15.0.874.102. Definitely, some useful error message is necessary.

BTW, this is the tornado commit that fixed the problem for them. I talked to Brian also about this, and I think the most sensible solution for our users is to apply that commit as a tornado monkeypatch for now. I'm going to submit a PR with the monkeypatch just now so that our regular users don't have to fight too much with this for now.

[fperez]

PR opened at #948 to take care of the tornado part. We'll close this once we also have a proper error message.

closed by merge of #948

I confirmed that this fixes it for me. I am closing the issue.

[fperez]

Nobody actually read my note above, did you ? :)

I deliberately did not close this issue until we also had a proper error message for the lack of websocket connections, though in all fairness that's a slightly different problem. I was just trying to keep things simple by having only open open issue around the whole problem.

Opened #952 then...

I was thinking about this, but then concluded that this issue really is fixed, and the warning is a different issue (but I should have opened the new issue for it), and then hit "comment & close", and then I noticed, that Min has already closed it in the meantime.

Thanks for fixing it so fast! Everything works excellent for me again.
