+/**\file pkgcache.h
+ \brief pkgCache - Structure definitions for the cache file
+
+ The goal of the cache file is two fold:
+ Firstly to speed loading and processing of the package file array and
+ secondly to reduce memory consumption of the package file array.
+
+ The implementation is aimed at an environment with many primary package
+ files, for instance someone that has a Package file for their CD-ROM, a
+ Package file for the latest version of the distribution on the CD-ROM and a
+ package file for the development version. 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 <b>Cache file</b> 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.
+
+ <b>Note on Pointer access</b>
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:
+ <example>
+ void *Map = mmap(...);
+ Package *PkgList = (Package *)Map;
+ Header *Head = (Header *)Map;
+ char *Strings = (char *)Map;
+ cout << (Strings + PkgList[Head->HashTable[0]]->Name) << endl;
+ </example>
+ 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. */
