Feature changed by: JP Rosevear (jpr@novell.com) Feature #302119, revision 25 Title: Load package selector and libzypp only when needed openSUSE-10.3: Rejected by reject date: 2007-08-01 16:40:54 reject reason: Postponing. Priority Requester: Desirable Projectmanager: Important openSUSE-11.0: Rejected by reject date: 2008-04-28 13:42:30 reject reason: Did not make it, postponing. Priority Requester: Desirable Projectmanager: Important openSUSE-11.1: Candidate Priority Requester: Desirable Projectmanager: Important Requested by: Stefan Hundhammer Partner organization: openSUSE.org Description: The YaST2 UI should load the code for the package selector and libzypp only when needed. Not all applications / YaST2 modules need package selection code, yet for all of them the respective code from the YaST2 UI and libzypp is loaded. Discussion: #1: Stefan Hundhammer (2007-04-13 18:13:44) In the YaST2 Qt the package management related code is now moved to a separate plugin that is loaded upon demand only if the calling YCP application actually requests a PackageSelector widget. This reduces the memory footprint from 20 MB VmRSS minimum (HelloWorld. ycp) to 18 MB minimum (PackageSelector-empty.ycp). #3: Katarina Machalkova (2007-04-16 14:41: 35) Stano, do we want this for curses UI as well? If yes, than it's not 'done' ... #4: Stanislav Visnovsky (2007-04-16 14:47:02) (reply to #3) Agreed. Reopening for ncurses and possibly gtk+. #5: Jiri Srain (2007-06-13 13:54:26) JP, both Qt and NCurses are done, but GTK is still missing. #6: Stefan Hundhammer (2007-06-13 15:08:58) Looks like yast2-pkg-bindings are also loaded unconditionally. It shouldn't be too hard to do that with "lazy initialization" like UI built-ins: Postpone loading the Y2Component until it's really needed. #7: Stanislav Visnovsky (2007-06-19 15:01:54) (reply to #6) Jiri, if Pkg bindings problem is not addressed, it does not make sense to fix Gtk UI. #8: Jiri Srain (2007-07-18 13:59:50) (reply to #7) Sorry for missing this. Martin, please, solve this for the Pkg bindings. #10: Stanislav Visnovsky (2007-11-08 11:38:22) (reply to #9) Please, follow up on this. #11: Martin Vidner (2008-04-10 15:23:51) yast2-perl-bindings-2.16.6 no longer links to libzypp, which means libzypp will not be loaded at the very start of yast (perl still will be loaded, but that is relatively cheap). That helps in some cases, but mostly it only delays loading of libzypp, which occurs as soon as Pkg (or Package) is imported. Now I need to make Pkg lazy. #12: Martin Vidner (2008-04-21 15:32:09) I have it almost working, but got stopped by bug 381917 (https://bugzilla.novell.com/show_bug.cgi?id=381917) : problems with destructors of static objects + #13: JP Rosevear (2008-07-21 13:59:18) (reply to #12) + Martin, what's the status here? Will we need to do anything explicit in + packagekit to get this functionality? -- openSUSE Feature: https://features.opensuse.org/?rm=feature_show&id=302119
