Subject: What's cooking in git.git (Apr 2024, #02; Wed, 3)

From: Junio C Hamano <[email-masked]>
Date: Wed, 03 Apr 2024 16:12:41 -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/

* bl/cherry-pick-empty (2024-03-25) 7 commits
  (merged to 'next' on 2024-03-28 at 22e8e4a68e)
 + cherry-pick: add `--empty` for more robust redundant commit handling
 + cherry-pick: enforce `--keep-redundant-commits` incompatibility
 + sequencer: do not require `allow_empty` for redundant commit options
 + sequencer: handle unborn branch with `--allow-empty`
 + rebase: update `--empty=ask` to `--empty=stop`
 + docs: clean up `--empty` formatting in git-rebase(1) and git-am(1)
 + docs: address inaccurate `--empty` default with `--exec`

 Allow git-cherry-pick(1) to automatically drop redundant commits via
 a new `--empty` option, similar to the `--empty` options for
 git-rebase(1) and git-am(1). Includes a soft deprecation of
 `--keep-redundant-commits` as well as some related docs changes and
 sequencer code cleanup.

  (merged to 'next' on 2024-03-28 at e2749914ab)
 + pretty: find pretty formats case-insensitively
 + pretty: update tests to use `test_config`

 The "--pretty=<shortHand>" option of the commands in the "git log"
 family, defined as "[pretty] shortHand = <expansion>" should have
 been looked up case insensitively, but was not, which has been
 corrected.

 A unit test for reftable code tried to enumerate all files in a

 the files it wanted to leave there, but was fooled by .nfs* cruft

* js/build-fuzz-more-often (2024-03-05) 3 commits
 - SQUASH???
 - fuzz: link fuzz programs with `make all` on Linux
 - ci: also define CXX environment variable

 In addition to building the objects needed, try to link the objects
 that are used in fuzzer tests, to make sure at least they build
 without bitrot, in Linux CI runs.

 Stalled.
