Would be super cool if we already have a PHP 8.4 image with WordPress to test the compatibility of plugins & themes.

Maybe @LaurentGoderre or @tianon can take a look at the PR?

[tianon]

This is a great idea! Unfortunately, it looks like we get hung up on Imagick/imagick#689 (and thus need Imagick/imagick#690). 😞

pecl imagick is basically unmaintained.

@thueske This adds necessary patches to this PR to make the build work with php 8.4: twiesing#1

[tianon]

Has there been any work in WordPress upstream to evaluate this dependency (and alternatives)?

[sebcode]

@tianon I’m not aware of any alternatives being actively considered. Imagemagick is the best option for processing images with PHP. GD is a works too but produces lower-quality images. Main issue is the lack of proper maintainer support of the pecl wrapper library. I think for now, the best approach is patching the library, which is also what Ondřej (maintainer of the widely-used PHP packages for Debian and Ubuntu) does.

Any updates based on this #932 (comment)? Would be great to have PHP 8.4 :)

[twiesing]

WordPress 6.7 adds PHP 8.4 beta support. The latest commit from imagick is Mar 18, 2023. I think the patch here from @sebcode is the best solution.

Some update on the ImageMagick side:

Imagick/imagick#690 (comment)

[tianon]

I've just force pushed this with a rebase+squash and an update to use the freshly-released https://pecl.php.net/package/imagick/3.8.0RC2 for PHP 8.4 (leaving other versions as-is on 3.7.0+patch given it's a pre-release).

Thank you! There aren't any multi-arch builds yet, is this a normal behavior?

Yeah, different architectures build at different speeds, and they are added to the image index as they are finished. We also merged a php security update at the same time, so the queues were (and are) still full for some architectures (https://doi-janky.infosiftr.net/). It looks like quite a few have finished building the wordpress:*php8.4* images and they are available on Docker Hub.
