Always present is the information + contained in the status file which might be considered a separate package + file. + + Please understand, this is designed as a Cache file it is not meant to be + used on any system other than the one it was created for. It is not meant to + be authoritative either, i.e. if a system crash or software failure occurs it + must be perfectly acceptable for the cache file to be in an inconsistent + state. Furthermore at any time the cache file may be erased without losing + any information. + + Also the structures and storage layout is optimized for use by the APT + and may not be suitable for all purposes. However it should be possible + to extend it with associate cache files that contain other information. + + To keep memory use down the cache file only contains often used fields and + fields that are inexpensive to store, the Package file has a full list of + fields. Also the client may assume that all items are perfectly valid and + need not perform checks against their correctness. Removal of information + from the cache is possible, but blanks will be left in the file, and + unused strings will also be present. The recommended implementation is to + simply rebuild the cache each time any of the data files change. It is + possible to add a new package file to the cache without any negative side + effects. + + Note on Pointer access Clients should always use the CacheIterators classes for access to the - cache. They provide a simple STL-like method for traversing the links - of the datastructure. - - See pkgcachegen.h for information about generating cache structures. - - ##################################################################### */ + cache and the data in it. They also provide a simple STL-like method for + traversing the links of the datastructure. + + Every item in every structure is stored as the index to that structure. + What this means is that once the files is mmaped every data access has to + go through a fix up stage to get a real memory pointer. This is done + by taking the index, multiplying it by the type size and then adding + it to the start address of the memory block. This sounds complex, but + in C it is a single array dereference. Because all items are aligned to + their size and indexes are stored as multiples of the size of the structure + the format is immediately portable to all possible architectures - BUT the + generated files are -NOT-. + + This scheme allows code like this to be written: + + void *Map = mmap(...); + Package *PkgList = (Package *)Map; + Header *Head = (Header *)Map; + char *Strings = (char *)Map; + cout << (Strings + PkgList[Head->HashTable[0]]->Name) << endl; + + Notice the lack of casting or multiplication. The net result is to return + the name of the first package in the first hash bucket, without error + checks. + + The generator uses allocation pools to group similarly sized structures in + large blocks to eliminate any alignment overhead. The generator also + assures that no structures overlap and all indexes are unique. Although + at first glance it may seem like there is the potential for two structures + to exist at the same point the generator never allows this to happen. + (See the discussion of free space pools) + + See \ref pkgcachegen.h for more information about generating cache structures. */ /*}}}*/ #ifndef PKGLIB_PKGCACHE_H #define PKGLIB_PKGCACHE_H +#include +#include #include #include -#include +#ifndef APT_8_CLEANER_HEADERS using std::string; - +#endif + class pkgVersioningSystem; class pkgCache /*{{{*/ { @@ -66,12 +124,20 @@ class pkgCache /*{{{*/ { enum DepType {Depends=1,PreDepends=2,Suggests=3,Recommends=4, Conflicts=5,Replaces=6,Obsoletes=7,DpkgBreaks=8,Enhances=9}; + /** \brief available compare operators + + The lower 4 bits are used to indicate what operator is being specified and + the upper 4 bits are flags.
