24 # NB: dak check-overrides is not a good idea with New Incoming as it #
25 # doesn't take into account accepted.  You can minimize the impact   #
26 # of this by running it immediately after dak process-accepted but   #
27 # that's still racy because 'dak process-new' doesn't lock with 'dak #
28 # process-accepted'.  A better long term fix is the evil plan for    #
29 # accepted to be in the DB.                                          #

32 # dak check-overrides should now work fine being done during
33 # cron.daily, for example just before 'dak make-overrides' (after 'dak
34 # process-accepted' and 'dak make-suite-file-list'). At that point,
35 # queue/accepted should be empty and installed, so... dak
36 # check-overrides does now take into account suites sharing overrides
37
38 # TODO:
39 # * Only update out-of-sync overrides when corresponding versions are equal to
40 #   some degree
41 # * consistency checks like:
42 #   - section=debian-installer only for udeb and # dsc
43 #   - priority=source iff dsc
44 #   - (suite, package, 'dsc') is unique,
45 #   - just as (suite, package, (u)deb) (yes, across components!)
46 #   - sections match their component (each component has an own set of sections,
47 #     could probably be reduced...)
