What's cooking in git.git (May 2022, #03; Tue, 10)

What's cooking in git.git (May 2022, #03; Tue, 10)

[Junio C Hamano]

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 2.36 release turned out to be a release with unusually high
number of regressions.  Git 2.36.1 has been tagged to deliver fixes
to a handful of them.

There unfortunately are a few more whose fixes have not been
adequately reviewed or agreed upon.

 - hooks no longer is connected directly to the standard output.
   cf. <CA+dzEBn108QoMA28f0nC8K21XT+Afua0V2Qv8XkR8rAeqUCCZw@mail.gmail.com>

 - "sudo make install" does not work out-of-the-box.
   cf. <4ef9287b-6260-9538-7c89-cffb611520ee@maurel.de>

These fixed soon, a new maintenance release needs to follow.

This cycle will conclude in early July (https://tinyurl.com/gitCal);
we are in week #3 of the cycle.

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:

 In Git 2.36 we revamped the way how hooks are invoked.  One change
 that is end-user visible is that the output of a hook is no longer
 directly connected to the standard output of "git" that spawns the
 hook, which was noticed post release.  This is getting corrected.

Thanks for picking it up! Unless others, e.g. Philippe, feel strongly
about the title, I'm not planning to retitle it.

I don't feel strongly about the title, so I also don't mind if you
choose to retitle it to whatever you wish.
