From 5bf15716398fdb767ca6249a0155219b88d7ae60 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Sat, 19 Dec 2009 16:25:56 +0100 Subject: Implement the first step toward Multi-Arch by setting up a Group infrastructor for packages. APT is now aware of the fact that a package A in architecture X can't satisfy a dependency on package A in architecture Y - to handle these packages are now identified by name and architecture, so different architectures of the same package are handled internally as completly different packages. This is great for pinning, dependency checking and in many other situations, but sometimes we need to know which archs are available for a given package: Here Groups come to our rescue! --- apt-pkg/pkgcachegen.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'apt-pkg/pkgcachegen.h') diff --git a/apt-pkg/pkgcachegen.h b/apt-pkg/pkgcachegen.h index 108b34207..4a2419b24 100644 --- a/apt-pkg/pkgcachegen.h +++ b/apt-pkg/pkgcachegen.h @@ -51,7 +51,8 @@ class pkgCacheGenerator /*{{{*/ // Flag file dependencies bool FoundFileDeps; - bool NewPackage(pkgCache::PkgIterator &Pkg,const string &PkgName); + bool NewGroup(pkgCache::GrpIterator &Grp,const string &Name); + bool NewPackage(pkgCache::PkgIterator &Pkg,const string &Name, const string &Arch); bool NewFileVer(pkgCache::VerIterator &Ver,ListParser &List); bool NewFileDesc(pkgCache::DescIterator &Desc,ListParser &List); unsigned long NewVersion(pkgCache::VerIterator &Ver,const string &VerStr,unsigned long Next); @@ -96,7 +97,7 @@ class pkgCacheGenerator::ListParser inline unsigned long WriteUniqString(const char *S,unsigned int Size) {return Owner->WriteUniqString(S,Size);}; inline unsigned long WriteString(const string &S) {return Owner->Map.WriteString(S);}; inline unsigned long WriteString(const char *S,unsigned int Size) {return Owner->Map.WriteString(S,Size);}; - bool NewDepends(pkgCache::VerIterator Ver,const string &Package, + bool NewDepends(pkgCache::VerIterator Ver,const string &Package, const string &Arch, const string &Version,unsigned int Op, unsigned int Type); bool NewProvides(pkgCache::VerIterator Ver,const string &Package, @@ -106,6 +107,7 @@ class pkgCacheGenerator::ListParser // These all operate against the current section virtual string Package() = 0; + virtual string Architecture() = 0; virtual string Version() = 0; virtual bool NewVersion(pkgCache::VerIterator Ver) = 0; virtual string Description() = 0; -- cgit v1.2.3-70-g09d2 From 25396fb06350344996a20d05423562f08a4165db Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Sun, 27 Dec 2009 19:39:47 +0100 Subject: Split ListParser::NewDepends into two methods to use these new method for creating the dependencies needed for our groups: For now for all groups only one package can be installed at the same time which conflicts with each other packages in the group.
