　　章节摘录

　　插图：Its important to see Git as something more than a version control system: Git is acontent tracking system. This distinction, however subtle, guides much of the design ofGit and is perhaps the key reason Git can perform internal data manipulations withrelative ease. Yet this is also perhaps one of the most difficult concepts for new usersof Git to grasp, so some exposition is worthwhile.Gits content tracking is manifested in two critical ways that differ fundamentally fromalmost all other* revision control systems.First, Gits object store is based on the hashed computation of the contents of its objects,not on the file or directory names from the users original file layout. Thus, when Gitplaces a file into the object store, it does so based on the hash of the data and not onthe name of the file. In fact, Git does not track file or directory names, which are asso-ciated with files in secondary ways. Again, Git tracks content instead of files.If two separate files located in two different directories have exactly the same content,Git stores a sole copy of that content as a blob within the object store. Git computesthe hash code of each file according solely to its content, determines that the files havethe same SHA1 values and thus the same content, and places the blob object in theobject store indexed by that SHA1 value. Both files in the project, regardless of wherethey are located in the users directory structure, use that same object for content.If one of those files changes, Git computes a new SHA1 for it, determines that it is nowa different blob object, and adds the new blob to the object store. The original blobremains in the object store for the unchanged file to use.Second, Gits internal database efficiently stores every version of every file——not theirdifferences——as files go from one revision to the next. Because Git uses the hash of afiles complete content as the name for that file, it must operate on each complete copyof the file. It cannot base its work or its object store entries on only part of the filescontent, nor on the differences between two revisions of that file.
