The maintenance page is deliberately rendered through the club's own
skin so it can show the club's logo -- but MaintenanceMiddleware closed
every path on a club subdomain unconditionally, including /media/. The
logo's <img> then pointed at a URL that itself returned the maintenance
page (503, text/html) instead of the image, so it rendered as broken.
/media/ moves into ALWAYS_OPEN, checked before the club-vs-platform
branch, so it now stays reachable on every host during a lock-down --
matching what OPEN_PREFIXES already granted the base domain, just never
extended to a club subdomain.
Closes every club subdomain with a 503 in that club's own colours, stands the
scheduled jobs down, and keeps open exactly what is needed to end it again.
The exemptions ARE the feature:
- /accounts/ stays open on the base domain. Close it too and you cannot sign in to
turn maintenance off -- a lock-down with no key, fixable only from a shell.
- /healthz answers on every host. Close it and the load balancer decides the node
is dead, stops routing to it, and takes the control panel down with everything
else.
- migrate and collectstatic are NOT blocked. Maintenance is usually declared in
order to run them; a blanket guard on BaseCommand would mean turning the mode off
to do the work you turned it on for. Only the domain jobs (archive_overdue_clubs,
extend_event_series, import_members_csv) refuse, and they exit non-zero so cron
mails you -- a scheduled job that silently skips itself is how a month of billing
goes missing.
The state is cached with a 10-second TTL, not for ever. Write-through makes the
flip instant for the shared Redis of a real deployment, and the TTL is the belt to
that braces: on a per-process cache -- a dev box with no Redis, or a misconfigured
deploy -- a lock-down that reached only one gunicorn worker would be worse than
useless. Live-verified: a club subdomain, its login page and the base domain all
503 while the control panel and the sign-in screens stay up.
Also adds the two deployment pieces asked for: compose.behind-proxy.yaml for a
dev/test box that already runs Caddy on :80 (app on the loopback, host Caddy proxies
to it -- and the host's Caddy still needs the DNS plugin, because the wildcard is
still a wildcard), and deploy/backup.sh + restore-check.sh with a cron schedule. The
backup writes to a .part file and only lands it once gzip -t says it is readable: a
truncated dump that looks like a backup is the failure you find on the day you need
it. The weekly restore rehearsal is the only line in that cron that proves the rest
work.
