From 9112f77703c39d46e2e0471c48c8a5e1f93f4abf Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Mon, 13 Jul 2015 03:36:59 +0200 Subject: show or-groups in not-installed recommends and suggests lists Further abstracting our new ShowList allows to use it for containers of strings as well giving us the option to implement an or-groups display for the recommends and suggests lists which is a nice trick given that it also helps with migrating the last remaining other cases of old ShowList. --- apt-private/private-install.cc | 135 ++++++++++++++++++++--------------------- 1 file changed, 67 insertions(+), 68 deletions(-) (limited to 'apt-private/private-install.cc') diff --git a/apt-private/private-install.cc b/apt-private/private-install.cc index cdca45755..0b5e33ae5 100644 --- a/apt-private/private-install.cc +++ b/apt-private/private-install.cc @@ -330,19 +330,17 @@ bool InstallPackages(CacheFile &Cache,bool ShwKept,bool Ask, bool Safety) } std::set const disappearedPkgs = PM->GetDisappearedPackages(); - if (disappearedPkgs.empty() == true) - return true; - - std::string disappear; - for (std::set::const_iterator d = disappearedPkgs.begin(); - d != disappearedPkgs.end(); ++d) - disappear.append(*d).append(" "); - - ShowList(c1out, P_("The following package disappeared from your system as\n" - "all files have been overwritten by other packages:", - "The following packages disappeared from your system as\n" - "all files have been overwritten by other packages:", disappearedPkgs.size()), disappear, ""); - c0out << _("Note: This is done automatically and on purpose by dpkg.") << std::endl; + if (disappearedPkgs.empty() == false) + { + ShowList(c1out, P_("The following package disappeared from your system as\n" + "all files have been overwritten by other packages:", + "The following packages disappeared from your system as\n" + "all files have been overwritten by other packages:", disappearedPkgs.size()), disappearedPkgs, + [](std::string const &Pkg) { return Pkg.empty() == false; }, + [](std::string const &Pkg) { return Pkg; }, + [](std::string const &) { return std::string(); }); + c0out << _("Note: This is done automatically and on purpose by dpkg.") << std::endl; + } return true; } @@ -699,8 +697,7 @@ bool DoInstall(CommandLine &CmdL) /* Print out a list of suggested and recommended packages */ { - std::string SuggestsList, RecommendsList; - std::string SuggestsVersions, RecommendsVersions; + std::list Recommends, Suggests, SingleRecommends, SingleSuggests; for (auto const &Pkg: Universe) { /* Just look at the ones we want to install */ @@ -714,77 +711,79 @@ bool DoInstall(CommandLine &CmdL) pkgCache::DepIterator Start; pkgCache::DepIterator End; D.GlobOr(Start,End); // advances D + if (Start->Type != pkgCache::Dep::Recommends && Start->Type != pkgCache::Dep::Suggests) + continue; - // FIXME: we really should display a or-group as a or-group to the user - // the problem is that ShowList is incapable of doing this - std::string RecommendsOrList,RecommendsOrVersions; - std::string SuggestsOrList,SuggestsOrVersions; - bool foundInstalledInOrGroup = false; - for(;;) { - /* Skip if package is installed already, or is about to be */ - pkgCache::PkgIterator const TarPkg = Start.TargetPkg(); - if (TarPkg->SelectedState == pkgCache::State::Install || - TarPkg->SelectedState == pkgCache::State::Hold || - Cache[Start.TargetPkg()].Install()) - { - foundInstalledInOrGroup=true; - break; - } - - /* Skip if we already saw it */ - std::string target = Start.TargetPkg().FullName(true) + " "; - if (int(SuggestsList.find(target)) != -1 || int(RecommendsList.find(target)) != -1) + // Skip if we already saw this + std::string target; + for (pkgCache::DepIterator I = Start; I != D; ++I) { - foundInstalledInOrGroup=true; - break; + if (target.empty() == false) + target.append(" | "); + target.append(I.TargetPkg().FullName(true)); } + std::list &Type = Start->Type == pkgCache::Dep::Recommends ?
