Subject: What's cooking in git.git (Feb 2022, #06; Wed, 23)

From: Junio C Hamano <[email-masked]>
Date: Wed, 23 Feb 2022 19:40:23 -0800

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.

Many topics have no summary written yet for them in this issue.

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):

  (merged to 'next' on 2022-02-14 at 6c8fd1f37f)
 + log: add a --no-graph option
 + log: fix memory leak if --graph is passed multiple times

 "git log --graph --graph" used to leak a graph structure, and there
 was no way to countermand "--graph" that appear earlier on the
 command line.  A "--no-graph" option has been added and resource
 leakage has been plugged.

  (merged to 'next' on 2022-02-10 at 213f44aec8)
 + receive-pack: purge temporary data if no command is ready to run

 "receive-pack" checks if it will do any ref updates (various
 conditions could reject a push) before received objects are taken
 out of the temporary directory used for quarantine purposes, so
 that a push that is known-to-fail will not leave crufts that a
 future "gc" needs to clean up.

 "worktree" itself wasn't, which has been corrected.

 + t0012: verify that built-ins handle `-h` even without gitdir

 "git cmd -h" outside a repository should error out cleanly for many
 commands, but instead it hit a BUG(), which has been corrected.

* ps/avoid-unnecessary-hook-invocation-with-packed-refs (2022-01-17) 6 commits
  (merged to 'next' on 2022-02-10 at 4866a64508)
 + refs: skip hooks when deleting uncovered packed refs
 + refs: do not execute reference-transaction hook on packing refs
 + refs: demonstrate excessive execution of the reference-transaction hook
 + refs: allow skipping the reference-transaction hook
 + refs: allow passing flags when beginning transactions
 + refs: extract packed_refs_delete_refs() to allow control of transaction

 Because a deletion of ref would need to remove it from both the
 loose ref store and the packed ref store, a delete-ref operation
 that logically removes one ref may end up invoking ref-transaction
 hook twice, which has been corrected.

 involved in the change.

 . http-backend: give a hint that web browser access is not supported

 When the http-backend program, which is the server-side component
 for the smart HTTP transport, sends a "404 Not found" error, we
 deliberately did not say anything to the requesting client.  We now
 send a message back to the browser to tell the user that they do
 not want to visit the URL via their browser, instead of a totally
 blank page.

 - receive-pack: check if client is alive before completing the push

 "git push" may be killed by the user when the server side has
 finished receiving all data and is about to commit the result.
 Give the latter a better chance to notice such situation and abort
 processing the ref updates.

 Needs more work?

* js/apply-partial-clone-filters-recursively (2022-02-09) 1 commit
  (merged to 'next' on 2022-02-16 at 4b3852bd52)
 + clone, submodule: pass partial clone filters to submodules

 "git clone --filter=... --recurse-submodules" only makes the
 top-level a partial clone, while submodules are fully cloned.  This
 behaviour is changed to pass the same filter down to the submodules.

* rs/bisect-executable-not-found (2022-01-19) 4 commits
 - bisect--helper: double-check run command on exit code 126 and 127
 - bisect: document run behavior with exit codes 126 and 127
 - bisect--helper: release strbuf and strvec on run error
 - bisect--helper: report actual bisect_state() argument on error

 A not-so-common mistake is to write a script to feed "git bisect
 run" without making it executable, in which case all tests will
 exit with 126 or 127 error codes, even on revisions that are marked
 as good.  Try to recoginse this situation and stop iteration early.

 - Provide config option to expect files outside sparse patterns
  (merged to 'next' on 2022-02-15 at 960873fdad)
 + Accelerate clear_skip_worktree_from_present_files() by caching
 + Update documentation related to sparsity and the skip-worktree bit
 + repo_read_index: clear SKIP_WORKTREE bit from files present in worktree
 + unpack-trees: fix accidental loss of user changes
 + t1011: add testcase demonstrating accidental loss of user modifications
 + Merge branch 'vd/sparse-clean-etc' into en/present-despite-skipped

 In sparse-checkouts, files mis-marked as missing from the working tree
 could lead to later problems.  Such files were hard to discover, and
 harder to correct.  Automatically detecting and correcting the marking
 of such files has been added to avoid these problems.

 On hold.

 "git add -i" was rewritten in C some time ago and has been in
 testing; the reimplementation is now exposed to general public by
 default.

 On hold.
