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

From: Junio C Hamano <[email-masked]>
Date: Tue, 20 Jan 2026 04:10:19 -0800

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 are 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 an URL
to a message that raises issues but they are no means exhaustive.  A
topic without enough support may be discarded after a long period of
no activity (of course they can be resubmit 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/

Release tarballs are available at:

 - Merge branch 'jk/asan-bonanza' into jk/parse-int

 Dscho observed that SVN tests are taking too much time in CI leak
 checking tasks, but most time is spent not in our code but in libsvn
 code (which happen to be written in Perl), whose leaks have little
 value to discover for us.  Skip SVN, P4, and CVS tests in the leak
