What's cooking in git.git (Mar 2022, #06; Mon, 28)

What's cooking in git.git (Mar 2022, #06; Mon, 28)

[Junio C Hamano]

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.

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/

Release tarballs are available at:

* gc/recursive-fetch-with-unused-submodules (2022-03-16) 10 commits
  (merged to 'next' on 2022-03-17 at 2813b7b1c3)
 + submodule: fix latent check_has_commit() bug
 + fetch: fetch unpopulated, changed submodules
 + submodule: move logic into fetch_task_create()
 + submodule: extract get_fetch_task()
 + submodule: store new submodule commits oid_array in a struct
 + submodule: inline submodule_commits() into caller
 + submodule: make static functions read submodules from commits
 + t5526: create superproject commits with test helper
 + t5526: stop asserting on stderr literally
 + t5526: introduce test helper to assert on fetches

 When "git fetch --recurse-submodules" grabbed submodule commits
 that would be needed to recursively check out newly fetched commits
 in the superproject, it only paid attention to submodules that are
 in the current checkout of the superproject.  We now do so for all
 submodules that have been run "git submodule init" on.

 + core.fsync: documentation and user-friendly aggregate options
 + core.fsync: new option to harden the index
 + core.fsync: add configuration parsing
 + core.fsync: introduce granular fsync control infrastructure
 + core.fsyncmethod: add writeout-only mode
 + wrapper: make inclusion of Windows csprng header tightly scoped
 (this branch is used by ns/batch-fsync and ps/fsync-refs.)

 Replace core.fsyncObjectFiles with two new configuration variables,
 core.fsync and core.fsyncMethod.

* ps/fsync-refs (2022-03-15) 2 commits
  (merged to 'next' on 2022-03-17 at 9e007c1178)

 + Merge branch 'ns/core-fsyncmethod' into ps/fsync-refs
 (this branch uses ns/core-fsyncmethod.)

 Updates to refs traditionally weren't fsync'ed, but we can
 configure using core.fsync variable to do so.

I think we're good to go.  Part 2 now includes all of the

seen any further feedback.

I have no opinion on the topic itself (haven't looked in detail, and I
don't use vim), but FWIW I've gotthis patch to fix the 2x new warnings
on "make check-doc" it triggered:
https://lore.kernel.org/git/patch-1.1-4a5d219dfe7-20220327T131751Z-avarab@gmail.com/

It has a trivial conflict (to that same check!) with my 3e05ff3e147 (CI:
have "static-analysis" run "check-builtins", not "documentation",
2022-03-25) in seen, but perhaps worth picking up...

There's a fix for this series at:
https://lore.kernel.org/git/pull.1191.git.1648590113062.gitgitgadget@gmail.com/
<pull.1191.git.1648590113062.gitgitgadget@gmail.com>

The net effect of the bug being fixed is that anyone using the default
core.fsync config is syncing everything except loose objects.

Apologies for the bug. I noticed it when revising the perf tests and
debugging the number of fsyncs. I'm submitting a separate patch to
log fsync info through trace2.

Thanks,
Neeraj
