Mediatex 0.9: motd

5.3.6 motd

The Motd process display the list of supports the MEDIATEX system wants to check or extract for, and the archives that needs to be put on external supports to be safe.

Process conceptual model:

Motd use 3 options defined into the /etc/mediatex/mdtx.conf (see mdtx.conf) file:

checkTTL: The time interval we have to re-check supports before MEDIATEX considers them obsolete (In this case, scores are impacted now ; but you ever can provide the support after and recover your previous scores).
fileTTL: Twice the time interval MEDIATEX will automatically re-check support’s files.
motdPolicy: Set to “All” if all images must be retrieve localy. Default is ’Most’ to only retrieve localy images having a bad score.

Events in

$ mediatex motd

- supports needed to extract local or remote remands,
- cache content to put on external supports.

Mediatex's message of the day
*****************************
Please provide theses local supports:
- AAA: periodic check, coll1
- ZZZ: coll1, coll2
Please burn theses files:
- Collection coll1:
 - /var/cache/mediatex/mdtx1/cache/mdtx1-coll1/aaa (-1.00)
 - /var//cache/mediatex/mdtx1/cache/mdtx1-coll1/zzz (-1.00)
Please remove theses local supports:
- /HERE/misc/logo.png: not used
- SUPP11_logo.png: coll1

Notice:

First stanza ask PUBLISHER to provide ($ mediatex check supp supp on file) supports either because it wasn’t checked for too long time or because it is needed in order to extract some content for a collection.
Second stanza ask PUBLISHER to fix some cache content into a new support ($ mediatex add supp supp on path or $ mediatex add file path followed by $ mediatex add supp supp to (all|coll coll)).
Third stanza notify PUBLISHER that some supports may be removed because either it is no more used by any collection or because another safe support already include it.
