DiskCache (via) Grant Jenks built DiskCache as an alternative caching backend for Django (also usable without Django), using a SQLite database on disk. The performance numbers are impressive—it even beats memcached in microbenchmarks, due to avoiding the need to access the network.
The source code (particularly in core.py) is a great case-study in SQLite performance optimization, after five years of iteration on making it all run as fast as possible. # 19th March 2024, 3:43 pm
djngo.com: Portable Django (via) “A 20mb executable zip file with Python 3.6 and Django 2.2. Works on Windows, Linux, MacOSX with x86_64 and aarch64 (yes, Apple M1 and Raspberry Pi).” The latest wizardry from the ecosystem surrounding the Cosmopolitan project, which provides a should-be-impossible mechanism for running the same executable on a bunch of different platforms. This utility by Ariel Núñez bundles Python and Django and SQLite, such that a Django application can become a portable executable ready to run on multiple platforms. It’s currently limited to Python 3.6 and Django 2.2 since those are the versions that run under Cosmopolitan, but I expect we’ll see more recent versions of those dependencies in the future. # 24th February 2023, 12:52 am
Weeknotes: DjangoCon, SQLite in Django, datasette-gunicorn
I spent most of this week at DjangoCon in San Diego—my first outside-of-the-Bay-Area conference since the before-times.
[... 1184 words]Bedrock: The SQLitening (via) Back in March 2018 www.mozilla.org switched over to running on Django using SQLite! They’re using the same pattern I’ve been exploring with Datasette: their SQLite database is treated as a read-only cache by their frontend servers, and a new SQLite database is built by a separate process and fetched onto the frontend machines every five minutes by a scheduled task. They have a healthcheck page which shows the latest version of the database and when it was fetched, and even lets you download the 25MB SQLite database directly (I’ve been exploring it using Datasette). # 7th October 2020, 11:47 pm
Logging to SQLite using ASGI middleware
I had some fun playing around with ASGI middleware and logging during our flight back to England for the holidays.
[... 2535 words]Django Unit Tests and Transactions. If you’re using a transactional database engine (MySQL with InnoDB, Postgres or SQLite) you can speed things up by running each of your unit tests inside a transaction and rolling back in tearDown(). # 7th July 2008, 2:14 pm
Exciting developments with Django
The amount of activity surrounding the Django web framework since its not-quite release a few weeks ago is amazing. Adrian, Jacob and Wilson have been working over-time, with 395 check-ins to source control since the 13th of July. They’ve added WSGI support, a development web server, unit-tests, a ton of documentation, SQLite support, database introspection and dozens of other feature tweaks and bug fixes. Check out the project Timeline for an idea of just how frenetic things have been.
