"Is Rust a great fit for this project?" I get this question quite frequently so I think it's time to write down my thoughts if it can avoid you some painful and costly mistakes. Short answer: no. Coming from someone who wrote a successful book about Rust (Black Hat Rust)
They removed a flag that didn’t do anything any more. It also didn’t hurt anybody, but since they removed it, my JavaScript project doesn’t build on Python 3.11 and needs Python 3.10. I can’t upgrade the version of node-gyp, because it’s a transitive dependency of another package I can’t upgrade.
So first of all, I had to upgrade something from Python 2.something to 3.something. I forget the specifics of what went wrong, but modern versions of pip just do not handle Python2 gracefully, at least when working with virtual environments. I tried to freeze to get a list of current dependencies, but pip freeze in a virtualenv just ended up writing out the system’s packages, not those in the virtual environment. I get it, Python2 isn’t officially supported any more, but at the same time, why is a language version not supported? Why is it not handled gracefully? This doesn’t happen in other programming languages.
Anyway, as for bumping up through Python 3 versions. I used a framework to do most of the heavy lifting in my project, but I think Python 3.8 or 3.9 introduced some syntax changes which made it not compatible any more. Changing how string literals are handled, and adding/removing arguments to functions. So I had to bump to a new version of the framework. Of course, because this was a webdev project, updating the framework also meant changing my project itself because of the “move quickly and break things” mindset that they have. So yeah, bumping up through versions of my framework until I got to one which was officially supported with the current python version.
I also used a python program to automatically run some scripts on boot. Turns out a while ago they decided that they wanted to redesign how they did everything, so you have to know to use the 1.x branch (which is still being updated) rather than the 2.x branch.
It honestly feels like everyone has a mindset that anything you write in Python and Node will be perpetually updated, and that long term maintenance isn’t a thing that happens. That you should always be using the latest version of anything.
And yes, I know I could probably work around all of this using Anaconda or docker or some other rube goldberg machine of programs. But I can’t be bothered dealing with that nonsense. I just want to keep something I wrote many years ago running.
If I start a new webdev project, I’m just going to use some Rust framework for the backend, and plain JS for the frontend.
I work on a team that has some old projects in python that we’re gradually deprecating. A major one is stuck on 3.7 because 3.8 added automatic async mocking (which is great!), but this broke the existing third-party async mocking framework and it’s never been updated to be compatible with newer Python versions. So we’d have to invest time in porting all the tests from the 3rd-party framework to the standard library, but it’s not worth it because we’re hoping to deprecate the whole project soon anyway.
Those doesn’t break backwards compatibility though. Naturally you can’t use match with a python 3.7 interpreter, but what scripts written for python 3.7 wouldn’t work with a 3.11 interpreter?
I haven’t encountered that issue before, so I’m curious what those problems OP have encountered looks like.
That honestly makes me curious, what issues have you encountered when upgrading your python(3) version?

That’s interesting, thanks for the reply

Some wheel didn’t install for me, so I downgraded 1 minor version and then it installed. Some cuda wheel I think.

I think they introduce new keywords every now and then. Match and async I think?
Edit: I was wrong, this is done in a backwards compatible manner

Huh, ok. I thought something like
match = 0in an old script might break a more recent version.But you may very well be correct.
matchisn’t a protected keyword likeifis.match = 0 match match: case 0: print(0) case _: print(1)Is legal and will give print out 0.
Well, today I learned. Thanks for pointing it out.
