write_entry: untangle symlink and regular-file cases The write_entry() function switches on the mode of the entry we're going to write out. The cases for S_IFLNK and S_IFREG are lumped together. In earlier versions of the code, this made some sense. They have a shared preamble (which reads the blob content), a short type-specific body, and a shared conclusion (which writes out the file contents; always for S_IFREG and only sometimes for S_IFLNK). But over time this has grown to make less sense. The preamble now has conditional bits for each type, and the S_IFREG body has grown a lot more complicated. It's hard to follow the logic of which code is running for which mode. Let's give each mode its own case arm. We will still share the conclusion code, which means we now jump to it with a goto. Ideally we'd pull that shared code into its own function, but it touches so much internal state in the write_entry() function that the end result is actually harder to follow than the goto. While we're here, we'll touch up a few bits of whitespace to make the beginning and endings of the cases easier to read.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
