We are preparing to migrate production MediaWiki from PHP 8.1 to 8.3 (T360995). The CLI images used by mediawiki-dumps-legacy will migrate as part of this effort.
The purpose of this task is to audit the configuration of mediawiki-dumps-legacy etc. for potential incompatibilities with 8.3 and resolve them.
Timeline: We're currently targeting the start of Q2 to begin migrating production traffic-serving workloads. Ideally, any preparation work required for dumps would complete on a similar time frame, to unblock initial testing of dumps on 8.3 in parallel with that.
As of this writing, the only known incompatibilities are explicit references to /usr/bin/php8.1 in configuration files bundled with chart carried over from puppet. Those should be straightforward to switch to /usr/bin/php.
