# Apply any pending SQL migrations before Apache starts to serve traffic, so
# the request path can simply CHECK the schema state and refuse to serve when
# something is unexpectedly out of date — no half-applied DDL hazard.
#
# Failure here aborts the container start (we exit non-zero) so the operator
# notices in `docker logs`. Apache otherwise picks up the trailing args
# verbatim (CMD `apache2-foreground`).

# past `gc_maxlifetime`. This backgrounded loop deletes session files
# older than $SESSION_GC_MAX_AGE_MINUTES every $SESSION_GC_INTERVAL_SECONDS.
# It is a child of this script's PID 1, so a `docker stop` propagates and
# tears it down cleanly along with Apache. No new package dependency — only
# coreutils' `find`, already present in the php:8.3-apache base image.
