Happy Holidays from the App Engine team - 1.4.0 SDK released

Re:Happy Holidays from the App Engine team - 1.4.0 SDK released by wkornewald on Thursday December 02, 2010 @03:45PM (#1963584)

This release solves almost all problems we had with App Engine. Users now don't have to wait for an instance to start, so the site will always be fast. Also, DeadlineExceededError now can't lead to mysteriously broken instances, anymore (thanks Guido!). And with the Channel API we can build real-time collaborative apps.

Now we only need SSL support and here we come, blasting everyone away who wastes time on maintaining his own servers. :P Well, at least until the next feature is needed, but not available, so let's hope this won't be the case. ;)

Note that the increase in the deadline to 10 minutes only affects background tasks (ie, the Task Queue and Cron jobs). It's important, but won't fix those DeadlineExceededError on a user-facing page errors on it's own.

What the parent is referring to is that when a Python process gets the DeadlineExceededError, it will now be recycled. Previously it would be re-used, and this would break things if the error happened in the middle of a module import (because the module would not be re-imported). Django was especially vulnerable to this.

Thanks - I wasn't aware of this (I do mostly Java stuff).

I'd imagine that the "warmup request" thing is especially useful for avoiding this.

Indeed. Pre-warmup request, GAE would start sending requests to instances that were started but weren't fully loaded.
