Open floor
- @spacedmonkey: Wondering if anyone would be interested in Convert heic to a web safe image form #53645? It’s the default format that iPhone cameras save to; wondering if we can make it web safe. A good first step might be to convert these files and then work out the kinks.
- @masteradhoc: We deal with this a lot. Lots of people connect their phones to Mac or Windows and drag and drop their pictures to a folder, then upload to WP.
- @johnbillion: The WP app on iPhone auto-converts HEIC to JPEG on the device before upload
- @spacedmonkey: If you send a HEIC via email or upload via a file input, iOS converts it to a web safe JPEG, but if you upload or drag in MacOS, it doesn’t convert
- @codekraft: Imagemagick can support it but it needs libheif
- @gilzow: The WebP conversion is specifically for performance; building something for one OS that’s not for optimization seems a bit too narrow and outside of the scope of this group
- @johnbillion: Seems like a good fit for a standalone feature plugin
- @shetheliving: Agreed, seems like this is out of scope for our group but could still be very useful
- @spacedmonkey: Would love to see Cache the results of the posts_request_ids query #22176 in core. Now that FSE uses a lot of
WP_Posts, lots moreWP_Queriesare run per page and they should be cached if possible. Needs a lot of unit tests and testing; created a core patch - @pbearne: See also Add filters to allow the shortcut return to wp_load_alloptions #56045 (@mukesh27 will take a look) and Introduce a general `pre_option` filter in `get_option()` #37930 (@spacedmonkey will take a look)
