Subject: What's cooking in git.git (Jun 2022, #05; Thu, 16)

From: Junio C Hamano <[email-masked]>
Date: Thu, 16 Jun 2022 17:15:29 -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.

The first -rc for this cycle is expected to be tagged tomorrow.

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/

Release tarballs are available at:

* jc/revert-show-parent-info (2022-05-31) 2 commits
  (merged to 'next' on 2022-06-07 at e405211ff4)

  (merged to 'next' on 2022-05-30 at b5da52dc14)
 + revert: optionally refer to commit in the "reference" format

 "git revert" learns "--reference" option to use more human-readable
 reference to the commit it reverts in the message template it
 prepares for the user.

 Various error messages that talk about the removal of
 "--preserve-merges" in "rebase" have been strengthened, and "rebase
 --abort" learned to get out of a state that was left by an earlier
 use of the option.

 - fetch,fetch-pack: clarify connectivity check error

 We may find an object missing after a "git fetch" stores the
 objects it obtained from the other side, but it is not necessarily
 because the remote failed to send necessary objects.  Reword the
 messages in an attempt to help users explore other possibilities
 when they hit this error.

* cb/path-owner-check-with-sudo-plus (2022-05-12) 1 commit
 - git-compat-util: allow root to access both SUDO_UID and root owned

 "sudo git foo" used to consider a repository owned by the original
 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).

* ar/send-email-confirm-by-default (2022-04-22) 1 commit
 - 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?
