datasette 1.0a40

Release: datasette 1.0a40

Same security fix as 0.65.5, plus some neat new features and bug fixes:

  • Plugins can now launch and manage background tasks using the new datasette.add_background_task() method. Thanks, Alex Garcia.
  • I've migrated Datasette to httpx2 for features like the internal datasette.client.get() method.
  • A whole lot of bug fixes, many of them stemming from a recent effort to triage issues for a 1.0 stable release.

Quoting Mustafa Suleyman

We should not treat models as though they have feelings, preferences, rights, or any entitlement to our welfare. Consciousness is the foundation of our ethical, legal, and political systems. To invite another entity to share any flavor of these rights isn’t justified by the evidence and will make the AI containment and alignment challenge even harder.

Quoting Laurie Voss

The cost of writing code collapsed, and the cost of reviewing, fixing and operating it is following, and I'm assuming it gets there. What's left of making software is finding out what people actually want, defining it precisely, and making it pleasant to use. That cost is per piece of software and doesn't transfer, so as the amount of software goes to infinity, which it will because there's no ceiling on demand, that cost becomes the whole job.

commit-rewriter 0.1

Release: commit-rewriter 0.1

I built this little web app the other day to help edit the commit messages for the Datasette security releases. The initial commits were full of coding agent cruft and references to issue IDs from our private repository, so they weren't fit for publication.

If you want to edit the commit messages for a repository you can run it like this:

uvx commit-rewriter path/to/repo

Omit the path if you are already in the directory for that repo.

Screenshot of the commit-rewriter web interface. A heading reads commit-rewriter above the repository path and current branch and commit hash, with a short description of the tool. A toolbar shows a pending edits count with Discard drafts and Rewrite commit messages buttons, followed by a search box for message, author, or hash and an Edited only checkbox. A left sidebar titled Navigate commits lists recent commit messages with their short hashes. The main panel shows a card for each commit with its hash, author and timestamp, an editable text area containing the commit message, and a View full formatted diff toggle.

When you submit your edits the tool creates a timestamped branch of your current repo state - to allow you to revert if you need to - and then rewrites every commit from the first one you edited to the most recent.

shot-scraper 1.12

Release: shot-scraper 1.12

I've added WebP support to my shot-scraper screenshot automation tool. You can now take a WebP screenshot of a web page like this:

shot-scraper https://simonwillison.net -o screenshot.webp --quality 80

The --quality option sets the quality - without that option the WebP file will be lossless.

In my experience WebP screenshots are almost always significantly smaller in file size than their JPEG or PNG equivalents. See the PR for some examples.

I shipped this feature so I could use it to generate the screenshot for my new commit-rewriter tool.

Generating running routes with GPT-6 Astra and ChatGPT Work

Here's a neat thing I had ChatGPT Work with GPT-6 Astra (Max) do this morning:

I live at <my address>. Figure out 5K and 10K running routes from me that loop from my house. Use OSM data.

It worked for 27 minutes and produced exactly what I'd asked for, as both an embedded visualization and downloadable GPX file and GeoJSON files. Here's that 5K route:

Map screenshot showing a blue route line over a light grey street map. Text: El Granada harbor loop 5.1 km. N ↑ (top right). Street labels along the route: Carmel Avenue, Paloma Avenue, San Carlos Avenue, Avenue Granada, Capistrano Road, Francisco Street, Coastal Trail. The loop runs from the harbor at the bottom left, north along Avenue Granada and Paloma Avenue to a northern point near Carmel Avenue, then east along San Carlos Avenue and south down Francisco Street to the far right, before returning west along the Coastal Trail beside the coastline. Footer: Map data © OpenStreetMap contributors. Give feedback.

Quoting Paul Ford

For a while, I must admit, it looked as if software developer roles like mine were done for. How could we fight against tireless robots? But our industry is slowly realizing that making truly cutting-edge software still requires humans to think and work together, to maximize their skill sets and to practice their respective crafts. A.I. can write very good software, but it also makes it easy to do someone else’s job badly, which is part of why all those projects fail. Now that everyone can code, it’s become clearer why many shouldn’t.

Quoting Boris Cherny

Production code written by Claude should have a higher bar than if it was written by a human. At Anthropic, we have many guardrails in place to make sure this is happening: lots of lint rules, lots of tests, Claude-driven end to end tests, Claude-powered fuzzers running daily, automated code reviews and security reviews, automated code refactoring, and so on. Without these, you can end up with a mess that is hard to maintain down the line.

Soft-deprecating re.match()

Soft-deprecating re.match()

Python has a concept of soft deprecation, where APIs are marked as "should no longer be used to write new code" without any promise/threat to remove them in the future.

Python 3.15 release manager Hugo van Kemenade describes how in the upcoming 3.15 release soft deprecation has come for the venerable but deeply confusing re.match() function. It's now available with the much clearer alternative re.prefixmatch() name - reflecting how it anchors at the beginning of the string but not the end.

Most of the time you probably want re.search() (match this pattern anywhere in the string) or re.fullmatch() (match the entire string) instead.

Datasette 1.0a39 and 0.65.4 security releases

Datasette 1.0a39 and 0.65.4 security releases

Today we're releasing two new security patch versions of Datasette: 1.0a39 and 0.65.4 - one for the current alpha series and one for the stable 0.65.x family.

These are security fixes which you should apply if you are running a Datasette instance on the public web - in particular if that instance mixes both public and private tables.

Following issues reported by Sevban Dönmez, Alex Garcia and I ran an extensive audit of Datasette using Claude Fable 5.1, GPT-5.6, and GPT-6 Astra. We then spent almost a week collaborating on and reviewing the fixes.

They helped find some very subtle bugs. We'll be incorporating security audits by frontier models into all of our development work going forward.
