Subject: What's cooking in git.git (Mar 2022, #02; Mon, 7)

From: Junio C Hamano <[email-masked]>
Date: Mon, 07 Mar 2022 17:51:19 -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',
which means nothing more than that I have found them of interest for
some reason (like "it may have hard-to-resolve conflicts with
another topic already in flight" or "this may turn out to be
useful").  Do not read too much into a topic being in (or not in)
'seen'.  The ones marked with '.' do not appear in any of the
integration branches, but I am still holding onto them.

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/

 exit with 126 or 127 error codes, even on revisions that are marked
 as good.  Try to recognize this situation and stop iteration early.

 . http-backend: give a hint that web browser access is not supported

 When the http-backend program, which is the server-side component
 for the smart HTTP transport, sends a "404 Not found" error, we
 deliberately did not say anything to the requesting client.  We now
 send a message back to the browser to tell the user that they do
 not want to visit the URL via their browser, instead of a totally
 blank page.

 - worktree: add -z option for list subcommand

 "git worktree list --porcelain" did not c-quote pathnames and lock
 reasons with unsafe bytes correctly, which is worked around by
 introducing NUL terminated output format with "-z".

 as $A's upstream only when $A and $B shares the same name, and "git
 -c push.default=simple" on branch $A would push to update the
 branch $A at the remote $B came from.

 When "git fetch --recurse-submodules" grabbed submodule commits
 that would be needed to recursively check out newly fetched commits
 in the superproject, it only paid attention to submodules that are
 in the current checkout of the superproject.  We now do so for all
 submodules that have been run "git submodule init" on.
