Details:
Import/Export will (probably be implemented implemented in next CERN branch.
Basic plan:
---------------
Format:
xml files will be structured in a way they could contain as many items as
necessary, mentionning to which group they belong.
They won't contain item id. They wont contain user_id and group_id but user
unix names and group unix names. Id are site-specific, they should stay that
way.
The structure will have to include for each item every necessary info (CC and
whatever)
Import method:
Import will be done by adding xml files to load on a specific place in the
server.
This should be done occasionally, run by the site admin -- but it could be
automatized easily.
A backend script will parse (using perl XML modules) the file and will handle
by himself the insert. No mail notification will be sent, no action will be
done on the items, considering we are simply importing data of already
performed actions. Not acting on items.
Ideally, this should also support bugzilla xml export.
Export method:
Like for the digest, users, via the web interface, will be able to select a
list of items (list of items or list of criteria that will be used to define
the items). Once satisfied with their list, they will submit the list, this
will be stored in the database, and a cronjob will make the backend building
the xml file in a specific directory, available via apache.
The idea of letting the frontend doing would pose too many problems: it wont
scale if someone wants to work with more than 50 items, it will make the
server collapse if persons does plenty of time the same request at the same
time, it will make complicated to deal with server load (not making easy to
let that job being done by another machine).
Later, it will be possible to imagine allow people to ask for a specific xml
export to be done everyweek at a specific hour, or whatever.
