Nagy Gabor 882bff36ac Remove find_replacements() ... "Foo replaces bar" simply means that "foo is a new version of bar". So this patch refactors the code to use this "rule". _alpm_sync_sysupgrade now does the following for each local package [bar] (pseudo-code): for db in syncdbs { if(db contains bar) {check if db/bar is an upgrade; break;} replacers = find(bar replacers in db); if(replacers!=NULL) {ask_user; break;} } Note: 1. Replacers are grouped per repo. If more than one package replace bar in a repo, all of them are considered ("package set of bar replacers"). 2. If repo1/foo1 and repo2/foo2 both replaces bar, only repo1/foo1 is considered (if repo1 stands before repo2 in pacman.conf). FS#11737 is fixed. 3. It can happen that pacman doesn't consider any replacer, if it found a literal "earlier", so sync132.py modified accordingly (btw, that situation should not appear irl). The new sysupgrade code doesn't use sync_newversion(), so I removed the "local is newer than repo" message, which was annoying with -Qu and SyncFirst.
