Still relevant as of 8.3.0~rc3-1+ubuntu22.04.1+deb.sury.org+1 on 2023-10-07..

@Reedy: Is this a blocker for T339350, or why was this ticket filed here? Wondering about the bigger picture that I lack (plus no project team tag/workboard).

Yeah, no idea why I didn't add it as a subtask when it replaced T344555: php8.3-mbstring not packaged yet (after that was fixed).

But in many ways this is also a "a list of reasons most MW installs probably won't work on PHP 8.3" (at least on Debian etc).

PHP 8.3.0 was released yesterday; November 23, 2023.

Still waiting on these packages, hopefully should appear "soon" now things are fully stable...

We probably don't really care much about the tideways package; xdebug is probably a bit more important (for developer stuff), but doesn't so much block the CI images.

I'm certainly able to move my MW dev env over to PHP 8.3 now, and it seemingly works (not tested in anger), as the majority of the packages needed are there.

https://github.com/oerdnj/deb.sury.org/issues/2034#issuecomment-1826113266 suggests the remaining (for us, in this case, xdebug especially) should appear over the weekend...

Onto some testing!

php8.3-memcached appears to not exist yet?

Pretty sure I installed it, because my dev wiki won’t work without it..

Maybe it’s done for Ubuntu, but not Debian yet?

Will check when I get home…

That seems to be everything bar tideways now, at least on Ubuntu; with T348379: Migrate use of php-tideways_xhprof to php-xhprof we probably don't really care about tideways either
