What's cooking in git.git (Jun 2022, #03; Fri, 10)

[Junio C Hamano <gitster@pobox.com>]

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.

This cycle will complete at around the end of June
(https://tinyurl.com/gitCal); -rc0 and -rc1 are scheduled to happen
next week.

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-vcs/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/

 - branch: check for bisects and rebases
 - branch: add branch_checked_out() helper

 Introduce a helper to see if a branch is already being worked on
 (hence should not be newly checked out in a working tree), which
 performs much better than the existing find_shared_symref() to
 replace many uses of the latter.

 We may find an object missing after a "git fetch" stores the

 because the remote failed to send necessary objects.  Reword the

 user a safe one to access; it now also considers a repository owned
 by root a safe one, too (after all, if an attacker can craft a
 malicious repository owned by root, the box is 0wned already).

 directly connected to the standard output of "git" that spawns the
 hook, which was noticed post release.  This is getting corrected.

 - send-email: always confirm by default

 "git send-email" is changed so that by default it asks for
 confirmation before sending each message out.

 Will discard.

 I wanted to like this, and had it in the version of Git I use
 myself for daily work, but the prompting turned out to be somewhat
 distracting.

 Thoughts?

* ds/rebase-update-refs (2022-06-07) 7 commits
 . rebase: add rebase.updateRefs config option
 . sequencer: implement 'update-refs' command
 . rebase: add --update-refs option
 . sequencer: add update-refs command
 . sequencer: define array with enum values
 . branch: add branch_checked_out() helper
 . log-tree: create for_each_decoration()

 "git rebase" learns "--update-refs" to update the refs that point
 at commits being rewritten so that they point at the corresponding
 commits in the rewritten history.

 Retracted for possible future redesign.
