[yast-devel] libzypp-4.6.1: Allow prioritizing repos.

JFYI: libzypp-4.6.1 now supports repo priorities. /etc/zypp/repos.d ----------------- Allow prioritizing repos (yum-priorities) by adding a line priority=N to the .repo file. Where N is an integer number from 1 (highest prio) to 99 (least and default). libzypp-4.6.1 ------------- The priority is stored in class zypp::RepoInfo: namespace zypp { class RepoInfo { /** * Repository priority for solver. * Some number between 1 (highest priority) and 99 (defaultPriority). */ unsigned priority() const; /** * Set repository priority for solver. * A newval_r of 0 sets the default priority. */ RepoInfo & setPriority( unsigned newval_r ); That's how you would e.g. change the priority of a repository in the pool: Repository myfave( sat::Pool::instance().reposFind( "myfave" ) ); if ( myfave ) { myfave.setInfo( myfave.info().setPriority( 2 ) ); } -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres YaST Development ma@novell.com 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: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

That's great, but ... ehm... what does it mean? I mean does it influence the solver or downloading a package in commit? Example situation: repository X with priority 99 containing package foo-1.0 repository Y with priority 90 containing package foo-0.9 repository Z with priority 95 containing package foo-1.0 User selects foo for installation. Which package will be installed? And what users expect to happen when they change priority of a repository? -- Best Regards Ladislav Slezák Yast Developer ------------------------------------------------------------------------ SUSE LINUX, s.r.o. e-mail: lslezak@suse.cz Lihovarská 1060/12 tel: +420 284 028 960 190 00 Prague 9 fax: +420 284 028 951 Czech Republic http://www.suse.cz/ -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

It influences the solver. The solver will prefer packages from repos with higher priority (which unfortunately is a lower number in yum-speak). Michael <mls> should be able to provide the exact details. AFAIK higher repo priority is prefered over version and arch.
AFAIK packages will be considered in this order a) package foo-0.9 (priority 90) b) package foo-1.0 (priority 95) c) package foo-1.0 (priority 99) but architecture/vendor of any installed foo may have an influence.
And what users expect to happen when they change priority of a repository? I don't think the solver is influenced yet.
No it works, and if something is wrong with it, it's missconfigured or a solver bug :) -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres YaST Development ma@novell.com 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: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

Wow! amazing, I thought the connection with solver's code is there, and what I told to Klaus is not true :-) Duncan -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

Just to make the picture complete (or raise the confusion ?), it should be mentioned that we intend to make all 'solver decisions' configurable through a policy plugin. Details have yet to be fleshed out ...
