  To: git

Here are the topics that have been cooking.  Commits prefixed with '-' are
only in 'seen' (formerly 'pu'---proposed updates) while commits prefixed
with '+' are in 'next'.  The ones marked with '.' do not appear in any of
the integration branches, but I am still holding onto 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/

  (merged to 'next' on 2021-03-30 at 701f5c0696)
 + csum-file: make hashwrite() more readable

 The hashwrite() API uses a buffering mechanism to avoid calling
 write(2) too frequently. This logic has been refactored to be
 easier to understand.

  (merged to 'next' on 2021-04-01 at 2e3c705a73)
 + sequencer: fix edit handling for cherry-pick and revert messages

 "git cherry-pick/revert" with or without "--[no-]edit" did not spawn
 the editor as expected (e.g. "revert --no-edit" after a conflict
 still asked to edit the message), which has been corrected.

  (merged to 'next' on 2021-03-31 at e0c4369f65)

 "git clone --reject-shallow" option fails the clone as soon as we
 notice that we are cloning from a shallow repository.

  (merged to 'next' on 2021-03-31 at 12bb775d9a)

  (merged to 'next' on 2021-04-01 at c8f43b1c8d)

 "git daemon" has been tightened against systems that take backslash
 as directory separator.


* tb/reverse-midx (2021-04-01) 17 commits
  (merged to 'next' on 2021-04-01 at 17c9542606)

 An on-disk reverse-index to map the in-pack location of an object
 back to its object name across multiple packfiles is introduced.


* zh/commit-trailer (2021-03-23) 1 commit
  (merged to 'next' on 2021-03-31 at f17d196ee1)
 + commit: add --trailer option
 (this branch is used by zh/trailer-cmd.)

 "git commit" learned "--trailer <key>[=<value>]" option; together
 with the interpret-trailers command, this will make it easier to
 support custom trailers.

 ... we would be much better off to say something like "somebody
 expected X to be a commit, but now somebody else expects it to be a
 blob", which is all that we can reliably say.

 Usage message fix for a test helper.

 Will merge to 'master'.


* jz/apply-run-3way-first (2021-04-06) 1 commit
 - git-apply: try threeway first when "--3way" is used
 (this branch is used by jz/apply-3way-cached.)

 "git apply --3way" has always been "to fall back to 3-way merge
 only when straight application fails". Swap the order of falling
 back so that 3-way is always attempted first (only when the option
 is given, of course) and then straight patch application is used as
 a fallback when it fails.

 Will merge to 'next'.


* ds/maintenance-prefetch-fix (2021-04-06) 5 commits
 - maintenance: allow custom refspecs during prefetch
 - test-tool: test refspec input/output
 - refspec: output a refspec item
 - test-lib: use exact match for test_subcommand
 - maintenance: simplify prefetch logic

 The prefetch task in "git maintenance" assumed that "git fetch"
 from any remote would fetch all its local branches, which would
 fetch too much if the user is interested in only a subset of
 branches there.

 - git-apply: allow simultaneous --cached and --3way options

 "git apply" now takes "--3way" and "--cached" at the same time, and
 work and record results only in the index.

 the trailer.<token>.cmd configuration variable, to replace it.

I split this up and will have a re-submission of it soon.

Let's discard it for now, I was looking it at today hoping to re-roll it
and saw that it some of the test-lib.sh changes would be a hassle for
me/you to manage with other things I have in-flight.

So I'll either submit it after that, or another version which doesn't
textually/semantically conflict like that, but in any case let's drop
this version.

I think so, it's trivial :)

FWIW to your suggestion of completion instead checking *_HEAD: As part
of another (abandoned for now) topic of mine I tried to exhaustively
enumerate all the magic all-caps refs just the test suite generates in
.git/FILE, and it's quite a big list.

So I found listing a new known one less scary.

Also, even though the bash completion is pretty bad about it now, I
thinkw we should aim more for it not needing to hit disk for completing
a thing like "git show REBASE_HE<TAB>" (which it'll needlessly do now).

Thanks. FWIW I kept hacking on send-email a bit, and have some local
patches that bring the runtime of t9001-send-email.sh from 30 seconds to
13, and a typical invocation time for git-send-email from ~250ms on my
box to ~40-60ms).

FWIW it seems it's now past that per
https://lore.kernel.org/git/xmqqblaoqtjf.fsf@gitster.g/ and this note
was added before that update to the thread.

I know you know that, just noting that for the benefit of others who are
following along.

I'd like that, some of the ORT code is over my head currently, but
having it tested by default would be very beneficial to smoke out any
bugs sooner than later.

I have an update in the pipeline that will address stale files on
Windows, and I can explode the series further. However, it is
fundamentally blocked on someone willing to spend some time reviewing
the series; this seems to be out of my control.
