fetch-pack: write fetched refs to .promisor The specification of promisor packfiles (in partial-clone.txt) states that the .promisor files that accompany packfiles do not matter (just like .keep files), so whenever a packfile is fetched from the promisor remote, Git has been writing empty .promisor files. But these files could contain more useful information. So instead of writing empty files, write the refs fetched to these files. This makes it easier to debug issues with partial clones, as we can identify what refs (and their associated hashes) were fetched at the time the packfile was downloaded, and if necessary, compare those hashes against what the promisor remote reports now. This is implemented by teaching fetch-pack to write its own non-empty .promisor file whenever it knows the name of the pack's lockfile. This covers the case wherein the user runs "git fetch" with an internal protocol or HTTP protocol v2 (fetch_refs_via_pack() in transport.c sets lock_pack) and with HTTP protocol v0/v1 (fetch_git() in remote-curl.c passes "--lock-pack" to "fetch-pack").

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://public-inbox.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):
