rector.php gets the PHP sets up to 8.5. Mostly constructor promotion with readonly properties, typed class constants, ??=, arrow functions, str_contains/str_starts_with, catch without unused variables, array_any and #[\Override] on overridden properties; array_key_exists() keys are cast to string (null keys are deprecated in PHP 8.5). Long promoted constructor signatures are wrapped one parameter per line. Checked locally: a crawl of ~1,900 frontend URLs over all sites and the backchannel APIs (/api/hotel, /api/product, content feed manifest and records of every type) render the same as before.

/**
|
|
* Points image URLs in frontend pages at the CDN (formerly EXT:replacer).
|
|
*
|
|
* Only images go to the CDN. The theme's own css/js/fonts are served by the production
|
|
* host: they are already minified by Webpack, gzipped by mod_deflate and content-hashed
|
|
* for a year of immutable browser caching, and keeping them on the page's own origin
|
|
* means they arrive over the connection the browser has already opened rather than
|
|
* costing a second DNS lookup and TLS handshake on the critical path.
|
|
*
|
|
* It also keeps them clear of the pull zone's habit of occasionally wedging a single
|
|
* cache key (10.0s -> 504 errorcode 106 until that key is purged, while the origin
|
|
* serves the same bytes in under 100ms). For an image that degrades one element; for
|
|
* js/main.<hash>.js it would take every visitor's JavaScript down.
|
|
*
|
|
* typo3temp is scoped to generated images on purpose - assets/compressed holds other
|
|
* extensions' concatenated css/js, which belongs on the origin for the same reason.
|
|
* The quote character is captured rather than matched literally, so url() values
|
|
* written with single quotes are rewritten too.
|
|
*
|
|
* Registered after the page resolver, so the /api/* responses of ep_products never pass here.
