// -*- mode: cpp; mode: fold -*- // Description /*{{{*/ /* ###################################################################### SourceList - Manage a list of sources The Source List class provides access to a list of sources. It can read them from a file and generate a list of all the distinct sources. All sources have a type associated with them that defines the layout of the archive. The exact format of the file is documented in files.sgml. The types are mapped through a list of type definitions which handle the actual construction of the back end type. After loading a source list all you have is a list of package index files that have the ability to be Acquired. ##################################################################### */ /*}}}*/ #ifndef PKGLIB_SOURCELIST_H #define PKGLIB_SOURCELIST_H #include <apt-pkg/macros.h> #include <apt-pkg/pkgcache.h> #include <time.h> #include <map> #include <string> #include <vector> #ifndef APT_8_CLEANER_HEADERS #include <apt-pkg/tagfile.h> #endif #ifndef APT_8_CLEANER_HEADERS #include <apt-pkg/metaindex.h> using std::string; using std::vector; #endif class FileFd; class pkgTagSection; class pkgAcquire; class pkgIndexFile; class metaIndex; class CommandLine; class pkgSourceList { void * const d; std::vector<pkgIndexFile*> VolatileFiles; public: // List of supported source list types class Type { public: // Global list of Items supported static Type **GlobalList; static unsigned long GlobalListLen; static Type *GetType(const char *Type) APT_PURE; char const * const Name; char const * const Label; bool FixupURI(std::string &URI) const; virtual bool ParseStanza(std::vector<metaIndex *> &List, pkgTagSection &Tags, unsigned int const stanza_n, FileFd &Fd); virtual bool ParseLine(std::vector<metaIndex *> &List, const char *Buffer, unsigned int const CurLine,std::string const &File) const; virtual bool CreateItem(std::vector<metaIndex *> &List,std::string const &URI, std::string const &Dist,std::string const &Section, std::map<std::string, std::string> const &Options) const = 0; Type(char const * const Name, char const * const Label); virtual ~Type(); }; typedef std::vector<metaIndex *>::const_iterator const_iterator; protected: std::vector<metaIndex *> SrcList; private: APT_HIDDEN bool ParseFileDeb822(std::string const &File); APT_HIDDEN bool ParseFileOldStyle(std::string const &File); public: bool ReadMainList(); bool Read(std::string const &File); // CNC:2003-03-03 void Reset(); bool ReadAppend(std::string const &File); bool ReadSourceDir(std::string const &Dir); // List accessors inline const_iterator begin() const {return SrcList.begin();}; inline const_iterator end() const {return SrcList.end();}; inline unsigned int size() const {return SrcList.size();}; inline bool empty() const {return SrcList.empty();}; bool FindIndex(pkgCache::PkgFileIterator File, pkgIndexFile *&Found) const; bool GetIndexes(pkgAcquire *Owner, bool GetAll=false) const; // query last-modified time time_t GetLastModifiedTime(); /** \brief add file for parsing, but not to the cache * * pkgIndexFiles origining from pkgSourcesList are included in * srcpkgcache, the status files added via #AddStatusFiles are * included in pkgcache, but these files here are not included in * any cache to have the possibility of having a file included just * for a single run like a local .deb/.dsc file. * * The volatile files do not count as "normal" sourceslist entries, * can't be iterated over with #begin and #end and can't be * downloaded, but they can be found via #FindIndex. * * @param File is an index file; pointer-ownership is transferred */ void AddVolatileFile(pkgIndexFile * const File); bool AddVolatileFile(std::string const &File); bool AddVolatileFile(std::string const &File, std::vector<std::string> * const VolatileCmdL); void AddVolatileFiles(CommandLine &CmdL, std::vector<std::string> * const VolatileCmdL); /** @return list of files registered with #AddVolatileFile */ std::vector<pkgIndexFile*> GetVolatileFiles() const; pkgSourceList(); virtual ~pkgSourceList(); }; #endif
