From https://github.com/moodleou/moodle-mod_oublog/issues/129

When running php admin/tool/phpunit/cli/init.php
I get the above error. The stack trace leads back to a oublog settings "hack" -

moodle-mod_oublog/settings.php

Line 17 in e4c2960
// Dodgy hack to setup the global blog instance (section not created yet on install).

This seems to be failing because of a recent update to Moodle: moodle/moodle@ea01fb2

Commenting out the oublog "hack" enabled installation to continue.

Moodle 4.1, PHP 8.0, MOODLE_311_STABLE branch of this plugin

This is due to cache_disabled not defining check_lock_state.
