Subject: What's cooking in git.git (Jun 2024, #04; Wed, 12)

From: Junio C Hamano <[email-masked]>
Date: Wed, 12 Jun 2024 17:30:04 -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 and may be annotated with an URL
to a message that raises issues but they are no means exhaustive.  A
topic without enough support may be discarded after a long period of
no activity (of course they can be resubmit when new interests
arise).

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-scm/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/

  (merged to 'next' on 2024-06-03 at 10b71e2a60)
 + t1517: more coverage for commands that work without repository
 (this branch is used by jk/imap-send-plug-all-msgs-leak.)

[Cooking]

* jk/am-retry (2024-06-06) 2 commits
  (merged to 'next' on 2024-06-10 at 4d62361bc7)
 + test-terminal: drop stdin handling
 + am: add explicit "--retry" option

 "git am" has a safety feature to prevent it from starting a new
 session when there already is a session going.  It reliably
 triggers when a mbox is given on the command line, but it has to
 rely on the tty-ness of the standard input.  Add an explicit way to
 opt out of this safety with a command line option.

 Will merge to 'master'.

 anywhere.

 into the base topic.

 - unbundle: support object verification for fetches

 Allow a server S that is a lazy clone of another repository X to
 respond to a request by C that is a lazy clone of S in a way that
 it omits objects it itself does not have (and has to be lazily
 fetched from X).

 I would say this is a terribly irresponsive design, especially
 there is no negociation for S to learn if the objects it is going
 to omit is obtainable by C from elsewhere.

* pw/rebase-i-error-message (2024-05-30) 2 commits
 - rebase -i: improve error message when picking merge
 - rebase -i: pass struct replay_opts to parse_insn_line()

 When the user adds to "git rebase -i" instruction to "pick" a merge
 commit, the error experience is not pleasant.  Such an error is now
 caught earlier in the process that parses the todo list.

 Expecting a reroll.

 The hashtable library "khash.h" has been replaced with "khashl.h"

 to switch on the hostname.

 Expecting a reroll.

 updated for a few commands to complete directory names where a
 directory name is expected.

 Command line completion support (in contrib/) has been taught to
 avoid offering revision names as candidates to "git send-email" when
 the command is used to send pre-generated files.

 Expecting a reroll.

* ps/ci-use-Og-in-some-jobs (2024-06-10) 2 commits
 . ci: compile "linux-gcc-default" job with -Og
 . Makefile: add ability to append to CFLAGS and LDFLAGS

 Compile with -Og, which is different from the usual -O2, in one CI
 job, to see if we can get more warning coverage.

 Discarded.
 False positives in "-Og -Wall -Werror" are too annoying.
