# --- Cleanup -----------------------------------------------------------------
|
|
|
|
#
|
|
# We have various levels of cleanup:
|
|
#
|
|
# - clean: remove left-over temporary files
|
|
# - rebuild: remove everything that can be rebuilt from cached data
|
|
# - update: remove the short-lived inventory and pricing cache too
|
|
# - again: remove also the long-lived equivalences cache
|
|
#
|
|
# "clean" does not disturb use of the database. The run-time cost of recovering
|
|
# from "rebuild" is small. What takes a lot of time is "update". The additional
|
|
# cost of "spotless" is small again.
|
|
