Allow checkout-index to use the parallel checkout framework, honoring the checkout.workers configuration. There are two code paths in checkout-index which call `checkout_entry()`, and thus, can make use of parallel checkout: `checkout_file()`, which is used to write paths explicitly given at the command line; and `checkout_all()`, which is used to write all paths in the index, when the `--all` option is given. In both operation modes, checkout-index doesn't abort immediately on a `checkout_entry()` failure. Instead, it tries to check out all remaining paths before exiting with a non-zero exit code. To keep this behavior when parallel checkout is being used, we must allow `run_parallel_checkout()` to try writing the queued entries before we exit, even if we already got an error code from a previous `checkout_entry()` call. However, `checkout_all()` doesn't return on errors, it calls `exit()` with code 128. We could make it call `run_parallel_checkout()` before exiting, but it makes the code easier to follow if we unify the exit path for both checkout-index modes at `cmd_checkout_index()`, and let this function take care of the interactions with the parallel checkout API. So let's do that. With this change, we also have to consider whether we want to keep using 128 as the error code for `git checkout-index --all`, while we use 1 for `git checkout-index <path>` (even when the actual error is the same). Since there is not much value in having code 128 only for `--all`, and there is no mention about it in the docs (so it's unlikely that changing it will break any existing script), let's make both modes exit with code 1 on `checkout_entry()` errors.

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
