In18c9cb7524(builtin/clone: create the refdb with the correct object format, 2023-12-12), we have changed git-clone(1) so that it delays creation of the refdb until after it has learned about the remote's object format. This change was required for the reftable backend, which encodes the object format into the tables. So if we pre-initialized the refdb with the default object format, but the remote uses a different object format than that, then the resulting tables would have encoded the wrong object format. This change unfortunately breaks remote helpers which try to access the repository that is about to be created. Because the refdb has not yet been initialized at the point where we spawn the remote helper, we also don't yet have "HEAD" or "refs/". Consequently, any Git commands ran by the remote helper which try to access the repository would fail because it cannot be discovered. This is essentially a chicken-and-egg problem: we cannot initialize the refdb because we don't know about the object format. But we cannot learn about the object format because the remote helper may be unable to access the partially-initialized repository. Ideally, we would address this issue via capabilities. But the remote helper protocol is not structured in a way that guarantees that the capability announcement happens before the remote helper tries to access the repository. Instead, fix this issue by partially initializing the refdb up to the point where it becomes discoverable by Git commands. ----- Cherry-picked the commit199f44cb2eto provide the backport-PR requested by @dscho in #4843 ...

Git for Windows
This is Git for Windows, the Windows port of Git.
The Git for Windows project is run using a governance model. If you encounter problems, you can report them as GitHub issues, discuss them on Git for Windows' Google Group, and contribute bug fixes.
To build Git for Windows, please either install Git for Windows'
SDK, start its git-bash.exe, cd
to your Git worktree and run make, or open the Git worktree as a folder in
Visual Studio.
To verify that your build works, use one of the following methods:
-
If you want to test the built executables within Git for Windows' SDK, prepend
<worktree>/bin-wrappersto thePATH. -
Alternatively, run
make installin the Git worktree. -
If you need to test this in a full installer, run
sdk build git-and-installer. -
You can also "install" Git into an existing portable Git via
make install DESTDIR=<dir>where<dir>refers to the top-level directory of the portable Git. In this instance, you will want to prepend that portable Git's/cmddirectory to thePATH, or test by running that portable Git'sgit-bash.exeorgit-cmd.exe. -
If you built using a recent Visual Studio, you can use the menu item
Build>Install git(you will want to click onProject>CMake Settings for Gitfirst, then click onEdit JSONand then pointinstallRootto themingw64directory of an already-unpacked portable Git).As in the previous bullet point, you will then prepend
/cmdto thePATHor run using the portable Git'sgit-bash.exeorgit-cmd.exe. -
If you want to run the built executables in-place, but in a CMD instead of inside a Bash, you can run a snippet like this in the
git-bash.exewindow where Git was built (ensure that theEOFline has no leading spaces), and then paste into the CMD window what was put in the clipboard:clip.exe <<EOF set GIT_EXEC_PATH=$(cygpath -aw .) set PATH=$(cygpath -awp ".:contrib/scalar:/mingw64/bin:/usr/bin:$PATH") set GIT_TEMPLATE_DIR=$(cygpath -aw templates/blt) set GITPERLLIB=$(cygpath -aw perl/build/lib) EOF -
If you want to run the built executables in-place, but outside of Git for Windows' SDK, and without an option to set/override any environment variables (e.g. in Visual Studio's debugger), you can call the Git executable by its absolute path and use the
--exec-pathoption, like so:C:\git-sdk-64\usr\src\git\git.exe --exec-path=C:\git-sdk-64\usr\src\git helpNote: for this to work, you have to hard-link (or copy) the
.dllfiles from the/mingw64/bindirectory to the Git worktree, or add the/mingw64/bindirectory to thePATHsomehow or other.
To make sure that you are testing the correct binary, call ./git.exe version
in the Git worktree, and then call git version in a directory/window where
you want to test Git, and verify that they refer to the same version (you may
even want to pass the command-line option --build-options to look at the
exact commit from which the Git version was built).
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 core 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 to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites. The core git mailing list is plain text (no HTML!).
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
