receive.denyCurrentBranch: respect all worktrees The receive.denyCurrentBranch config option controls what happens if you push to a branch that is checked out into a non-bare repository. By default, it rejects it. It can be disabled via `ignore` or `warn`. Another yet trickier option is `updateInstead`. However, this setting was forgotten when the git worktree command was introduced: only the main worktree's current branch is respected. With this change, all worktrees are respected. That change also leads to revealing another bug, i.e. `receive.denyCurrentBranch = true` was ignored when pushing into a non-bare repository's unborn current branch using ref namespaces. As `is_ref_checked_out()` returns 0 which means `receive-pack` does not get into conditional statement to switch `deny_current_branch` accordingly (ignore, warn, refuse, unconfigured, updateInstead). receive.denyCurrentBranch uses the function `refs_resolve_ref_unsafe()` (called via `resolve_refdup()`) to resolve the symbolic ref HEAD, but that function fails when HEAD does not point at a valid commit. As we replace the call to `refs_resolve_ref_unsafe()` with `find_shared_symref()`, which has no problem finding the worktree for a given branch even if it is unborn yet, this bug is fixed at the same time: receive.denyCurrentBranch now also handles worktrees with unborn branches as intended even while using ref namespaces.

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):
