Draft: Depool hosts only when needed based on check() (!14) · Merge requests · repos / data_persistence / dbtools / Auto Schema · GitLab

How to register an account on GitLab. Due to spam, new accounts are locked until approved by an admin or the approver bot. Your GitLab account gets automatically approved within one hour if you are a member of Trusted Contributors in Gerrit, or a member of the Trusted-Contributors group in Phabricator and linked your Developer account ("LDAP") to your Phabricator account. If none of these apply, file an unlock request to expedite access. Only if you are WMF staff: Create your GitLab account, have "Wmf" group membership in IDM, link your Developer account ("LDAP") to your Phabricator account, and get automatically approved.

Support: mw:GitLab, how to host a project on GitLab, #wikimedia-gitlab on libera.chat, #GitLab on Phabricator.

The check() call needs to be moved into the _per_replica_gen generator in order to silence/depool/repool conditionally. Sets a flag into Host to yield the check() output as needed. Add unit and functional tests.
