How we rolled out one of the largest Python 3 migrations ever. “If you’re using Dropbox today, the application is powered by a Dropbox-customized variant of Python 3.5” # 25th September 2018, 11:02 pm
Wagtail 2.0. The leading Django content management system just released it’s 2.0 version—now Django 2.0 and Python 3 only, and with a new rich text editor based on Draft.js. I really like Wagtail—it’s full-feature,d mature, well-documented and philosophically aligned with how I think a CMS should work. I also like this line about the new Python 3 requirement: “Call us reckless neophiles, but we think that, nine years in, Python 3 is looking pretty solid.” # 1st March 2018, 4:06 pm
Moving a large and old codebase to Python3 (via) Really interesting case study full of good ideas. The codebase in this case was 240,000 lines of Python and Django written over the course of 15 years. The team used Python-Modernize to aid their transition to a six-compatible codebase first. # 20th February 2018, 2:39 pm
Python & Async Simplified. Andrew Godwin: “Python’s async framework is actually relatively simple when you treat it at face value, but a lot of tutorials and documentation discuss it in minute implementation detail, so I wanted to make a higher-level overview that deliberately ignores some of the small facts and focuses on the practicalities of writing projects that mix both kinds of code.” This is really useful: clearly explains the two separate worlds of Python (sync and async functions) and describes Andrew’s clever sync_to_async and async_to_sync decorators as well. # 20th February 2018, 12:30 am
asgiref: AsyncToSync and SyncToAsync (via) Andrew’s classes in asgiref that can turn a synchronous callable into an awaitable (that runs in a thread pool) or an awaitable callable into a synchronous callable, using Python 3 futures and asyncio. # 2nd February 2018, 7:06 pm
Channels 2.0. Andrew just shipped Channels 2.0—a major rewrite and redesign of the Channels project he started back in 2014. Channels brings async to Django, providing a logical, standardized way of supporting things like WebSockets and asynchronous execution on top of a Django application. Previously it required you to run a separate Twisted server and redis/RabbitMQ queue, but thanks to Python 3 async everything can now be deployed as a single process. And the new ASGI spec means its turtles all the way down! Everything from URL routing to view functions to middleware can be composed together using the same ASGI interface. # 2nd February 2018, 6:19 pm
