Subject: What's cooking in git.git (Mar 2026, #06)

From: Junio C Hamano <[email-masked]>
Date: Mon, 16 Mar 2026 17:25:50 -0700

Here are the topics that have been cooking in my tree.  Commits
prefixed with '+' are in 'next' (being in 'next' is a sign that a
topic is stable enough to be used and is a candidate to be in a
future release).  Commits prefixed with '-' are only in 'seen', and
aren't considered "accepted" at all and may be annotated with a URL
to a message that raises issues but they are by no means exhaustive.
A topic without enough support may be discarded after a long period
of no activity (of course they can be resubmitted when new interests
arise).

Copies of the source code to Git live in many repositories, and the
following is a list of the ones I push into or their mirrors.  Some
repositories have only a subset of branches.

With maint, master, next, seen, todo:

	git://git.kernel.org/pub/scm/git/git.git/
	git://repo.or.cz/alt-git.git/
	https://kernel.googlesource.com/pub/scm/git/git/
	https://github.com/git/git/
	https://gitlab.com/git-scm/git/

With all the integration branches and topics broken out:

	https://github.com/gitster/git/

Even though the preformatted documentation in HTML and man format
are not sources, they are published in these repositories for
convenience (replace "htmldocs" with "manpages" for the manual
pages):

	git://git.kernel.org/pub/scm/git/git-htmldocs.git/
	https://github.com/gitster/git-htmldocs.git/

 While discovering a ".git" directory, the code treats any stat()
 failure as a sign that a filesystem entity .git does not exist
 there, and ignores ".git" that is not a "gitdir" file or a
 directory.  The code has been tightened to notice and report
 filesystem corruption better.

 "git checkout -m another-branch" was invented to deal with local
 changes to paths that are different between the current and the new
 branch, but it gave only one chance to resolve conflicts.  The command
 was taught to create a stash to save the local changes.
