# schedule selected packages for a rebuild
#
# This uses the following schedule:
# - find scheduleworthy packages by pkgname/pkgbase (broken
#   dependencies, explicite regex) and their architecture
# - remove all ignored packages (seed-ignore, explicitely ignored,
#   blacklist)
# - run mysql_generate_package_metadata on each of them once (ignoring
#   the architecture for now)

# shellcheck source=../lib/load-configuration
. "${0%/*}/../lib/load-configuration"

# TODO: allow to reschedule filtered by architecture

# TODO: remove hard-coded package suffixes

# TODO: -a reschedules too many packages (for example, packages, that have just been rescheduled in a previous run)

# TODO: -a and -p leave the buildmaster in an unclean state
