urpm::main_loop(3) Mageia Package Management urpm::main_loop(3)NAMEurpm::main_loop - The install/remove main loop for urpm based programs
(urpmi, gurpmi, rpmdrake, drakx)
SYNOPSISDESCRIPTION
run($urpm, $state, $something_was_to_be_done, $ask_unselect,
$callbacks)
Run the main urpm loop:
· mount removable media if needed
· split the work in smaller transactions
· for each transaction:
· prepare the transaction
· download packages needed for this small transaction
· verify packages
· split package that should be installed instead of upgraded,
· install source package only (whatever the user is root or
not, but use rpm for that)
· install/remove other packages
· migrate the chrooted rpmdb if needed
· display the final success/error message(s)
Warning: locking is left to callers...
