Jonathan Tan 301f1e3ac1 promisor-remote: die upon failing fetch In a partial clone, an attempt to read a missing object results in an attempt to fetch that single object. In order to avoid multiple sequential fetches, which would occur when multiple objects are missing (which is the typical case), some commands have been taught to prefetch in a batch: such a command would, in a partial clone, notice that several objects that it will eventually need are missing, and call promisor_remote_get_direct() with all such objects at once. When this batch prefetch fails, these commands fall back to the sequential fetches. But at $DAYJOB we have noticed that this results in a bad user experience: a command would take unexpectedly long to finish (and possibly use up a lot of bandwidth) if the batch prefetch would fail for some intermittent reason, but all subsequent fetches would work. It would be a better user experience for such a command would just fail. Therefore, make it a fatal error if the prefetch fails and at least one object being fetched is known to be a promisor object. (The latter criterion is to make sure that we are not misleading the user that such an object would be present from the promisor remote. For example, a missing object may be a result of repository corruption and not because it is expectedly missing due to the repository being a partial clone.)

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 and Documentation/CodingGuidelines).

Those wishing to help with error message, usage and informational message string translations (localization l10) should see po/README.md (a po file is a Portable Object file that holds the translations).

To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). 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
