Use a new REF_STATES_INIT designated initializer instead of assigning to the "strdup_strings" member of the previously memzero()'d version of this struct. The pattern of assigning to "strdup_strings" dates back to 211c89682ee (Make git-remote a builtin, 2008-02-29) (when it was "strdup_paths"), i.e. long before we used anything like our current established *_INIT patterns consistently. Then in e61e0cc6b70 (builtin-remote: teach show to display remote HEAD, 2009-02-25) and e5dcbfd9ab7 (builtin-remote: new show output style for push refspecs, 2009-02-25) we added some more of these. As it turns out we only initialized this struct three times, all the other uses were of pointers to those initialized structs. So let's initialize it in those three places, skip the memset(), and pass those structs down appropriately. This would be a behavior change if we had codepaths that relied say on implicitly having had "new_refs" initialized to STRING_LIST_INIT_NODUP with the memset(), but only set the "strdup_strings" on some other struct, but then called string_list_append() on "new_refs". There isn't any such codepath, all of the late assignments to "strdup_strings" assigned to those structs that we'd use for those codepaths. So just initializing them all up-front makes for easier to understand code, i.e. in the pre-image it looked as though we had that tricky edge case, but we didn't.

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-<commandname>.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://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
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
