Jeff King ef4fe5617e connect.c: fix leak in parse_one_symref_info() If we successfully parse a symref value like "HEAD:refs/heads/master", we add the result to a string list. But because the string list is marked STRING_LIST_INIT_DUP, the string list code will make a copy of the string and add the copy. This patch fixes it by adding the entry with string_list_append_nodup(), which lets the string list take ownership of our newly allocated string. There are two alternatives that seem like they would work, but aren't the right solution. The first is to initialize the list with the "NODUP" initializer. That would avoid the copy, but then the string list would not realize that it owns the strings. When we eventually call string_list_clear(), it would not free the strings, causing a leak. The second option would be to use the normal string_list_append(), but free the local copy in our function. We can't do this because the local copy actually contains _two_ strings; the symref name and its target. We point to the target pointer via the "util" field, and its memory must last as long as the string list does. You may also wonder whether it's safe to ever free the local copy, since the target points into it. The answer is yes, because we duplicate it in annotaate_refs_with_symref_info before clearing the string list.

Git - fast, scalable, distributed revision control system

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):

random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
"global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
