Upgrade our internally maintained php7.2 packages to 7.2.22.
I'm running into a build failure, which I initially assumed was caused by DNS resolution in pbuilder/boron, but it's ultimately caused by MariaDB; the build calls mysql_install_db from the MariaDB package, which is broken by https://jira.mariadb.org/browse/MDEV-18526
I'm trying a few workarounds
The only thing scap does on the deployment servers via php is mwscript rebuildLocalisationCache.php. The php changelog seems like there are a lot of bugfixes between 7.2.8 (current version) and 7.2.22 without much else, so it doesn't seem worrisome to me; however, I haven't been following php7 development very closely.
One easiest way to test would be to run something like: mwscript rebuildLocalisationCache.php --wiki=enwiki --outdir=/tmp/php7.2.22-l10nupdate and ensure it runs without error and generates cdb files.
