Subject: What's cooking in git.git (Mar 2025, #07; Wed, 26)

From: Junio C Hamano <[email-masked]>
Date: Wed, 26 Mar 2025 05:46:00 -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 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).

I am still officially on vacation, but 2.50 cycle has been started
and the first batch of topics are now in 'master'.

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/

 - builtin/gc: split out function to expire reflog entries
 - builtin/reflog: make functions regarding `reflog_expire_options` public
 - builtin/reflog: stop storing per-reflog expiry dates globally

 "git maintenance" learns a new task to expire reflog entries.

 Needs (real) review.

 Certain "cruft" objects would have never been refreshed when there
 are multiple cruft packs in the repository, which has been
 corrected.

 . install meson for Documentation job
