Subject: What's cooking in git.git (Nov 2021, #07; Mon, 29)

From: Junio C Hamano <[email-masked]>
Date: Mon, 29 Nov 2021 18:16:54 -0800

As promised, most of the topics that have been cooking in 'next'
since the previous release cycle have been merged to 'master' to
start a new cycle, with a small exception.  The tip of 'next' has
been rewound and there is 0 topics on it right now.

The exception is 'ns/tmp-objdir' and a few topics that depend on it,
which are kicked out of 'next' to give the base topic a chance to
lose the two "fixup!" band-aid.  Careful re-reading of the topic by
somebody with a fresh set of eyes (meaning, everybody, as this has
been dormant for almost a month) is very much appreciated to move
things forward.  Also ns/remerge-diff that is Neeraj's rebase of the
remerge-diff topic needs Elijah's Ack at least.

Many of the new patches in 'seen' since the last cycle ended are
truly 'just seen' and not 'read' at all, as you can see from the
lack of any topic description to speak of in the following list.
Help is appreciated here, too.  Before whipping them into some
presentable shape, I wouldn't be able to take any more new topics.

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.

A few topics for regression fixes have been merged to 'next' and
will be merged to 'master' shortly.  There are many topics listed as
"New" that are in 'seen', but I haven't read many of them (and I
shouldn't have anyway, before dealing with regression fixes) and
haven't gave any summary comments in this report, either, yet.

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/

With all the integration branches and topics broken out:

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):

* jc/fix-ref-sorting-parse (2021-10-20) 2 commits
  (merged to 'next' on 2021-10-29 at e3ec6e8e77)
 + for-each-ref: delay parsing of --sort=<atom> options
 + Merge branch 'ab/ref-filter-leakfix' into jc/fix-ref-sorting-parse

 Things like "git -c branch.sort=bogus branch new HEAD", i.e. the

 sort key information, no longer errors out by seeing a bogus sort
 key.

 The compatibility implementation for unsetenv(3) were written to
 mimic ancient, non-POSIX, variant seen in an old glibc; it has been
 changed to return an integer to match the more modern era.

 - run-command: unify signal and regular logic for wait_or_whine()

 The function to cull a child process and determine the exit status
 had two separate code paths for normal callers and callers in a
 signal handler, and the latter did not yield correct value when the
 child has caught a signal.  The handling of the exit status has
 been unified for these two code paths.  An existing test with
 flakiness has also been corrected.

 "git submodule deinit" for a submodule whose .git metadata
 directory is embedded in its working tree refused to work, until
 the submodule gets converted to use the "absorbed" form where the
 metadata directory is stored in superproject, and a gitfile at the
 top-level of the working tree of the submodule points at it.  The
 command is taught to convert such submodules to the absorbed form

 - branch: protect branches checked out in all worktrees

 - fetch: protect branches checked out in all worktrees
 - worktree: simplify find_shared_symref() memory ownership model
 - branch: lowercase error messages
 - receive-pack: lowercase error messages

 "git fetch" without the "--update-head-ok" option ought to protect
 a checked out branch from getting updated, to prevent the working
 tree that checks it out to go out of sync.  The code was written
 before the use of "git worktree" got widespread, and only checked
 the branch that was checked out in the current worktree, which has
 been updated.
