Subject: What's cooking in git.git (Mar 2023, #03; Mon, 13)

From: Junio C Hamano <[email-masked]>
Date: Mon, 13 Mar 2023 11:28:40 -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.

Git 2.40 (final) has been tagged and pushed out and we have about
two dozens of topics in 'next'.  Let's spend this week to look for
regression reports and fix them, and to decide which ones to eject
out of 'next' as necessary.  I'll start moving stalled topics into
to-be-discarded bin and discard 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/
	https://github.com/gitster/git-htmldocs.git/

* ab/fix-strategy-opts-parsing (2023-03-08) 1 commit
  (merged to 'next' on 2023-03-08 at bd9eff2779)
 + sequencer.c: fix overflow & segfault in parse_strategy_opts()

 The code to parse "git rebase -X<opt>" was not prepared to see an
 unparsable option string, which has been corrected.

 Will cook in 'next'.

* fc/advice-diverged-history (2023-03-08) 1 commit
  (merged to 'next' on 2023-03-08 at 30e7016218)
 + advice: add diverging advice for novices

 After "git pull" that is configured with pull.rebase=false
 merge.ff=only fails due to our end having our own development, give
 advice messages to get out of the "Not possible to fast-forward"
 state.

* jk/add-p-unmerged-fix (2023-03-09) 1 commit
  (merged to 'next' on 2023-03-09 at a46443480c)
 + add-patch: handle "* Unmerged path" lines

 "git add -p" while the index is unmerged sometimes failed to parse
 the diff output it internally produces and died, which has been
 corrected.

* jk/format-patch-ignore-noprefix (2023-03-09) 5 commits
  (merged to 'next' on 2023-03-12 at 621d71c151)
 + format-patch: add format.noprefix option
 + format-patch: do not respect diff.noprefix
 + diff: add --default-prefix option
 + t4013: add tests for diff prefix options
 + diff: factor out src/dst prefix setup

 "git format-patch" honors the src/dst prefixes set to nonstandard
 values with configuration variables like "diff.noprefix", causing
 receiving end of the patch that expects the standard -p1 format to
 break.  Teach "format-patch" to ignore end-user configuration and
 always use the standard prefixes.

 This is a backward compatibility breaking change.

 "git receive-pack" that responds to "git push" requests failed to
 clean a stale lockfile when killed in the middle, which has been
 corrected.

 + parse-options: consistently allocate memory in fix_filename()
 + bundle: don't blindly apply prefix_filename() to "-"

 "git bundle" learned that "-" is a common way to say that the input
 comes from the standard input and/or the output goes to the
 standard output.  It used to work only for output and only from the
 root level of the working tree.

 + restore: fault --staged --worktree with merge opts

 "git restore" supports options like "--ours" that are only
 meaningful during a conflicted merge, but these options are only
 meaningful when updating the working tree files.  These options are
 marked to be incompatible when both "--staged" and "--worktree" are
 in effect.

 + fetch: support hideRefs to speed up connectivity checks

 A new "fetch.hideRefs" option can be used to exclude specified refs
 from "rev-list --objects --stdin --not --all" traversal for
 checking object connectivity, most useful when there are many
 unrelated histories in a single repository.

 + receive-pack: fix funny ref error messsage

 "git push" has been taught to allow deletion of refs with one-level
 names to help repairing a repository who acquired such a ref by
 mistake.  In general, we don't encourage use of such a ref, and
 creation or update to such a ref is rejected as before.

 . test: make SYMLINKS prerequisite more robust

 For some reason, "ln -s x y && test -h y" started passing on
 Windows, even though we do not have working readlink(3) there.
 Tighten the check to enable SYMLINKS prerequisite in our tests.

 It turns out that this was caused by using a faulty build of the
 Windows dev environment, which was fixed.
