From 803ea2a87f81252b2c0d541b8502ed206ce57c84 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Fri, 12 Feb 2010 00:04:31 +0100 Subject: Add yet another pseudo package which isn't as pseudo as the others: Arch all packages are now represented by arch depending packages which all depend on a package with the same name and the special arch "all". This packages has NO dependencies, but beside this the same information. It is the only package which has a size, the arch depending ones all have a zero size. While the arch depending pseudo packages are used for dependency resolution the arch "all" package is used for downloading and ordering of the package. --- apt-pkg/algorithms.cc | 52 ++++++++++++++++++++++++++++++++++++++++---- apt-pkg/cacheiterators.h | 1 + apt-pkg/deb/deblistparser.cc | 22 +++++++++++++++++-- apt-pkg/depcache.cc | 4 ++++ apt-pkg/depcache.h | 1 + apt-pkg/orderlist.cc | 4 ++++ apt-pkg/packagemanager.cc | 23 +++++++++++++++----- apt-pkg/pkgcache.cc | 12 ++++++++++ apt-pkg/pkgcache.h | 2 +- apt-pkg/pkgcachegen.cc | 20 +++++++++++++---- cmdline/apt-cache.cc | 2 ++ cmdline/apt-get.cc | 14 +++++++++--- 12 files changed, 137 insertions(+), 20 deletions(-) diff --git a/apt-pkg/algorithms.cc b/apt-pkg/algorithms.cc index 34da745de..c905cffa9 100644 --- a/apt-pkg/algorithms.cc +++ b/apt-pkg/algorithms.cc @@ -83,13 +83,28 @@ void pkgSimulate::Describe(PkgIterator Pkg,ostream &out,bool Current,bool Candid bool pkgSimulate::Install(PkgIterator iPkg,string /*File*/) { // Adapt the iterator - PkgIterator Pkg = Sim.FindPkg(iPkg.Name()); + PkgIterator Pkg = Sim.FindPkg(iPkg.Name(), iPkg.Arch()); Flags[Pkg->ID] = 1; cout << "Inst "; Describe(Pkg,cout,true,true); Sim.MarkInstall(Pkg,false); - + + if (strcmp(Pkg.Arch(),"all") == 0) + { + pkgCache::GrpIterator G = Pkg.Group(); + pkgCache::GrpIterator iG = iPkg.Group(); + for (pkgCache::PkgIterator P = G.FindPkg("any"); P.end() != true; P = G.NextPkg(P)) + { + if (strcmp(P.Arch(), "all") == 0) + continue; + if (iG.FindPkg(P.Arch())->CurrentVer == 0) + continue; + Flags[P->ID] = 1; + Sim.MarkInstall(P, false); + } + } + // Look for broken conflicts+predepends. for (PkgIterator I = Sim.PkgBegin(); I.end() == false; I++) { @@ -131,9 +146,22 @@ bool pkgSimulate::Install(PkgIterator iPkg,string /*File*/) bool pkgSimulate::Configure(PkgIterator iPkg) { // Adapt the iterator - PkgIterator Pkg = Sim.FindPkg(iPkg.Name()); + PkgIterator Pkg = Sim.FindPkg(iPkg.Name(), iPkg.Arch()); Flags[Pkg->ID] = 2; + + if (strcmp(Pkg.Arch(),"all") == 0) + { + pkgCache::GrpIterator G = Pkg.Group(); + for (pkgCache::PkgIterator P = G.FindPkg("any"); P.end() != true; P = G.NextPkg(P)) + { + if (strcmp(P.Arch(), "all") == 0) + continue; + if (Flags[P->ID] == 1) + Flags[P->ID] = 2; + } + } + // Sim.MarkInstall(Pkg,false); if (Sim[Pkg].InstBroken() == true) { @@ -181,10 +209,26 @@ bool pkgSimulate::Configure(PkgIterator iPkg) bool pkgSimulate::Remove(PkgIterator iPkg,bool Purge) { // Adapt the iterator - PkgIterator Pkg = Sim.FindPkg(iPkg.Name()); + PkgIterator Pkg = Sim.FindPkg(iPkg.Name(), iPkg.Arch()); Flags[Pkg->ID] = 3; Sim.MarkDelete(Pkg); + + if (strcmp(Pkg.Arch(),"all") == 0) + { + pkgCache::GrpIterator G = Pkg.Group(); + pkgCache::GrpIterator iG = iPkg.Group(); + for (pkgCache::PkgIterator P = G.FindPkg("any"); P.end() != true; P = G.NextPkg(P)) + { + if (strcmp(P.Arch(), "all") == 0) + continue; + if (iG.FindPkg(P.Arch())->CurrentVer == 0) + continue; + Flags[P->ID] = 3; + Sim.MarkDelete(P); + } + } + if (Purge == true) cout << "Purg "; else diff --git a/apt-pkg/cacheiterators.h b/apt-pkg/cacheiterators.h index e8cf28496..43cbe1377 100644 --- a/apt-pkg/cacheiterators.h +++ b/apt-pkg/cacheiterators.h @@ -200,6 +200,7 @@ class pkgCache::VerIterator : public Iterator { string RelStr(); bool Automatic() const; + bool Pseudo() const; VerFileIterator NewestFile() const; inline VerIterator(pkgCache &Owner,Version *Trg = 0) : Iterator(Owner, Trg) { diff --git a/apt-pkg/deb/deblistparser.cc b/apt-pkg/deb/deblistparser.cc index 3726a6a04..b3d95164a 100644 --- a/apt-pkg/deb/deblistparser.cc +++ b/apt-pkg/deb/deblistparser.cc @@ -148,6 +148,24 @@ bool debListParser::NewVersion(pkgCache::VerIterator Ver) Ver->Priority = pkgCache::State::Extra; } + if (Ver->MultiArch == pkgCache::Version::All) + { + /* We maintain a "pseudo" arch=all package for architecture all versions + on which these versions can depend on.
