You know that feeling when you're working on a complex threading application and something just doesn't feel quite right? Well, the Python core team has been listening, and today's biggest story is all about making threading more reliable and predictable.
Let's jump right into the star of the show - a pull request by encukou that tackles a really interesting threading challenge. This change improves how PyErr_CheckSignals handles exceptions that are scheduled by PyThreadState_SetAsyncExc. Now, I know that sounds pretty technical, but here's the beautiful part - this…
But that's not all we're celebrating today. Thomas Kowalski brought us a seemingly small change that's actually quite brilliant - adding the `--no-install-recommends` flag to apt installations in the build process. And get this - it cuts build time from 51 seconds down to 25 seconds! That's more than a 50%…
We also saw some great community contributions rolling in. Stan Ulbrych added a workflow to verify the bundled libexpat library, which…
