Git does not record such an identifier, and this is claimed as an advantage.
 and recording this as a simple rename would freeze an inaccurate description of what happened in the (immutable) history.
This has some significant consequences:* It is slightly more expensive to examine the change history of a single file than the whole project.
 To obtain a history of changes affecting a given file, Git must walk the global history and then determine whether each change modified that file.
This method of examining history does, however, let Git produce with equal efficiency a single history showing the changes to an arbitrary set of files.
For example, a subdirectory of the source tree plus an associated global header file is a very common case.* Renames are handled implicitly rather than explicitly.
That's why we provide our guides, videos, and cheat sheets (about version control with Git and lots of other topics) for free.
Every Git working directory is a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server.
You can also overwrite this information just for a certain repository in that project's "Settings" view: exactly we change the information of past commits, there's one thing to always keep in mind: if we do this, we are effectively rewriting commit history.
Like , Bazaar and Monotone, Git gives each developer a local copy of the entire development history, and changes are copied from one such repository to another.
These changes are imported as additional development branches, and can be merged in the same way as a locally developed branch.* Repositories can be published via HTTP, FTP, ssh, , or a Git protocol.
As part of its toolkit design, Git has a well-defined model of an incomplete merge, and it has multiple algorithms for completing it, culminating in telling the user that it is unable to complete the merge automatically and manual editing is required.* Garbage accumulates unless collected.
Aborting operations or backing out changes will leave useless dangling objects in the database.
