// -*- mode: cpp; mode: fold -*- // Description /*{{{*/ /* ###################################################################### Package Manager - Abstacts the package manager Three steps are - Aquiration of archives (stores the list of final file names) - Sorting of operations - Invocation of package manager This is the final stage when the package cache entities get converted into file names and the state stored in a DepCache is transformed into a series of operations. In the final scheme of things this may serve as a director class to access the actual install methods based on the file type being installed. ##################################################################### */ /*}}}*/ #ifndef PKGLIB_PACKAGEMANAGER_H #define PKGLIB_PACKAGEMANAGER_H #include <apt-pkg/edsp.h> #include <apt-pkg/init.h> #include <apt-pkg/macros.h> #include <apt-pkg/pkgcache.h> #include <set> #include <string> #ifndef APT_10_CLEANER_HEADERS #include <apt-pkg/install-progress.h> #include <iostream> #endif #ifndef APT_8_CLEANER_HEADERS #include <apt-pkg/depcache.h> using std::string; #endif class pkgAcquire; class pkgDepCache; class pkgSourceList; class pkgOrderList; class pkgRecords; class OpProgress; class pkgPackageManager; namespace APT { namespace Progress { class PackageManager; } } class pkgPackageManager : protected pkgCache::Namespace { public: enum OrderResult {Completed,Failed,Incomplete}; static bool SigINTStop; protected: std::string *FileNames; pkgDepCache &Cache; pkgOrderList *List; bool Debug; bool NoImmConfigure; bool ImmConfigureAll; /** \brief saves packages dpkg let disappear This way APT can retreat from trying to configure these packages later on and a front-end can choose to display a notice to inform the user about these disappears. */ std::set<std::string> disappearedPkgs; void ImmediateAdd(PkgIterator P, bool UseInstallVer, unsigned const int &Depth = 0); virtual OrderResult OrderInstall(); bool CheckRConflicts(PkgIterator Pkg,DepIterator Dep,const char *Ver); bool CheckRBreaks(PkgIterator const &Pkg,DepIterator Dep,const char * const Ver); bool CreateOrderList(); // Analysis helpers bool DepAlwaysTrue(DepIterator D) APT_PURE; // Install helpers bool ConfigureAll(); bool SmartConfigure(PkgIterator Pkg, int const Depth) APT_MUSTCHECK; //FIXME: merge on abi break bool SmartUnPack(PkgIterator Pkg) APT_MUSTCHECK; bool SmartUnPack(PkgIterator Pkg, bool const Immediate, int const Depth) APT_MUSTCHECK; bool SmartRemove(PkgIterator Pkg) APT_MUSTCHECK; bool EarlyRemove(PkgIterator Pkg, DepIterator const * const Dep) APT_MUSTCHECK; APT_DEPRECATED bool EarlyRemove(PkgIterator Pkg) APT_MUSTCHECK; // The Actual installation implementation virtual bool Install(PkgIterator /*Pkg*/,std::string /*File*/) {return false;}; virtual bool Configure(PkgIterator /*Pkg*/) {return false;}; virtual bool Remove(PkgIterator /*Pkg*/,bool /*Purge*/=false) {return false;}; virtual bool Go(APT::Progress::PackageManager * /*progress*/) {return true;}; APT_DEPRECATED_MSG("Use overload with explicit progress manager") virtual bool Go(int /*statusFd*/=-1) {return true;}; virtual void Reset() {}; // the result of the operation OrderResult Res; public: // Main action members bool GetArchives(pkgAcquire *Owner,pkgSourceList *Sources, pkgRecords *Recs); // Do the installation OrderResult DoInstall(APT::Progress::PackageManager *progress); // compat APT_DEPRECATED_MSG("Use APT::Progress::PackageManager subclass instead of fd") OrderResult DoInstall(int statusFd=-1); friend bool EIPP::OrderInstall(char const * const planner, pkgPackageManager * const PM, unsigned int const version, OpProgress * const Progress); friend bool EIPP::ReadResponse(int const input, pkgPackageManager * const PM, OpProgress * const Progress); // stuff that needs to be done before the fork() of a library that // uses apt OrderResult DoInstallPreFork() { Res = OrderInstall(); return Res; }; // stuff that needs to be done after the fork OrderResult DoInstallPostFork(APT::Progress::PackageManager *progress); // compat APT_DEPRECATED_MSG("Use APT::Progress::PackageManager subclass instead of fd") OrderResult DoInstallPostFork(int statusFd=-1); // ? bool FixMissing(); /** \brief returns all packages dpkg let disappear */ inline std::set<std::string> GetDisappearedPackages() { return disappearedPkgs; }; explicit pkgPackageManager(pkgDepCache *Cache); virtual ~pkgPackageManager(); private: void * const d; enum APT_HIDDEN SmartAction { UNPACK_IMMEDIATE, UNPACK, CONFIGURE }; APT_HIDDEN bool NonLoopingSmart(SmartAction const action, pkgCache::PkgIterator &Pkg, pkgCache::PkgIterator DepPkg, int const Depth, bool const PkgLoop, bool * const Bad, bool * const Changed) APT_MUSTCHECK; }; #endif
