Hi,
We used libzypp-binding in MeeGo image creator, once one package is marked as installed by item.status().setToBeInstalled (zypp.ResStatus.USER), it can't be re-marked as uninstalled by item.status().setToBeUninstalled(zypp.ResStatus.USER), this is necessary if we don't want to install a package in a pattern, anybody knows there is a know way to do this? Thanks in advance.
setToBeInstalled: request to install a not yet installed package setToBeUninstalled: request to delete an already installed package To simply keep the package as it currently is (installed or not) you have basically 2 options: - setTransact(false, zypp.ResStatus.USER) - resetTransact(zypp.ResStatus.USER) Both will reset the status so there is no solver request created for this item. There is a slight - but sometimes important - difference in both calls: - setTransact(..) flags the status a 'set by USER'. The solver will NOT re-select this package in case it is just recommended by some other package to be installed. Only if the package is required, the solver will re-select it to prevent a dependency error. (If you want to prevent this from being selected even if it was required, you need to lock the item.) - resetTransact(..) clears all flags The solver is free to re-select this package even if it is just recommended by some other package. -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres ZYPP Development ma@suse.de SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) Maxfeldstrasse 5, D-90409 Nuernberg, Germany, ++49 (0)911 - 740 53-0 +------------------------------------------------------------------+ -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org
