Subject: What's cooking in git.git (May 2024, #12; Tue, 28)

From: Junio C Hamano <[email-masked]>
Date: Tue, 28 May 2024 15:45:05 -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).

We unfortunately had serious regressions in 2.45.1 (and below, down
to 2.39 maintenance track are affected), and we are trying to assess
the extent of damage and which changes that went into the release to
revert.  We know about "git lfs" and "git annex" getting affected.
We have bunch of reverts planned to fix these regressions that are
already in 'next'.  Please test it if you think you're affected, so
that we can have 2.45.2 and friends to fix these regressions early
next month.

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/

 - upload-pack: allow configuring a missing-action

 Allow a server S that is a lazy clone of another repository X to
 respond to a request by C that is a lazy clone of S in a way that
 it omits objects it itself does not have (and has to be lazily
 fetched from X).

 I would say this is a terribly irresponsive design, especially
 there is no negociation for S to learn if the objects it is going
 to omit is obtainable by C from elsewhere.

 + push: don't fetch commit object when checking existence

 When "git push" notices that the commit at the tip of the ref on
 the other side it is about to overwrite does not exist locally, it
 used to first try fetching it if the local repository is a partial

  (merged to 'next' on 2024-05-22 at ae8e378430)
 + refs/reftable: allow configuring geometric factor
 + reftable: make the compaction factor configurable
 + refs/reftable: allow disabling writing the object index
 + refs/reftable: allow configuring restart interval
 + reftable: use `uint16_t` to track restart interval
 + refs/reftable: allow configuring block size
 + reftable/dump: support dumping a table's block structure
 + reftable/writer: improve error when passed an invalid block size
 + reftable/writer: drop static variable used to initialize strbuf
 + reftable: pass opts as constant pointer
 + reftable: consistently refer to `reftable_write_options` as `opts`

 The knobs to tweak how reftable files are written have been made
 available as configuration variables.

 Will merge to 'master'.

  (merged to 'next' on 2024-05-08 at 9f8e894685)
 + repository: stop setting SHA1 as the default object hash
 + oss-fuzz/commit-graph: set up hash algorithm
 + builtin/shortlog: don't set up revisions without repo
 + builtin/diff: explicitly set hash algo when there is no repo
 + builtin/bundle: abort "verify" early when there is no repository
 + builtin/blame: don't access potentially unitialized `the_hash_algo`
 + builtin/rev-parse: allow shortening to more than 40 hex characters
 + remote-curl: fix parsing of detached SHA256 heads
 + attr: fix BUG() when parsing attrs outside of repo
 + attr: don't recompute default attribute source
 + parse-options-cb: only abbreviate hashes when hash algo is known
 + path: move `validate_headref()` to its only user
 + path: harden validation of HEAD with non-standard hashes
 + Merge branch 'ps/the-index-is-no-more' into ps/undecided-is-not-necessarily-sha1
 + Merge branch 'jc/no-default-attr-tree-in-bare' into ps/undecided-is-not-necessarily-sha1
 (this branch is used by jc/undecided-is-not-necessarily-sha1-fix.)

 Before discovering the repository details, We used to assume SHA-1
 as the "default" hash function, which has been corrected. Hopefully
 this will smoke out codepaths that rely on such an unwarranted
 assumptions.

 Will cook in 'next', as it has known breakage.

* pw/rebase-i-error-message (2024-04-08) 2 commits
 - rebase -i: improve error message when picking merge
 - rebase -i: pass struct replay_opts to parse_insn_line()

 When the user adds to "git rebase -i" instruction to "pick" a merge
 commit, the error experience is not pleasant.  Such an error is now
 caught earlier in the process that parses the todo list.

 Expecting a reroll.

* ew/khash-to-khashl (2024-03-28) 3 commits
 - khashl: fix ensemble lookups on empty table
 - treewide: switch to khashl for memory savings
 - list-objects-filter: use kh_size API

 The hashtable library "khash.h" has been replaced with "khashl.h"
 that has better memory usage characteristics.

 Needs review.

* ds/doc-config-reflow (2024-03-14) 1 commit
 - config.txt: perform some minor reformatting

 Reflow a paragraph in the documentation source without any effect
 to the formatted text.

 Will discard.

* ie/config-includeif-hostname (2024-03-19) 2 commits
 - config: learn the "hostname:" includeIf condition
 - t: add a test helper for getting hostname

 The conditional inclusion mechanism for configuration files learned
 to switch on the hostname.

 Expecting a reroll.

* cw/git-std-lib (2024-02-28) 4 commits
 . SQUASH??? get rid of apparent debugging crufts
 . test-stdlib: show that git-std-lib is independent
 . git-std-lib: introduce Git Standard Library
 . pager: include stdint.h because uintmax_t is used

 Split libgit.a out to a separate git-std-lib tor easier reuse.

 Expecting a reroll.

* bk/complete-dirname-for-am-and-format-patch (2024-01-12) 1 commit
 - completion: dir-type optargs for am, format-patch

 Command line completion support (in contrib/) has been
 updated for a few commands to complete directory names where a
 directory name is expected.

 Expecting a reroll.

* bk/complete-send-email (2024-01-12) 1 commit
 - completion: don't complete revs when --no-format-patch

 Command line completion support (in contrib/) has been taught to
 avoid offering revision names as candidates to "git send-email" when
 the command is used to send pre-generated files.

 Expecting a reroll.

 bump the format version to 2.
