Subject: What's cooking in git.git (May 2026, #05)

From: Junio C Hamano <[email-masked]>
Date: Wed, 20 May 2026 14:19:24 +0900

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 is a 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 a URL
to a message that raises issues but they are by no means exhaustive.
A topic without enough support may be discarded after a long period
of no activity (of course they can be resubmitted when new interests
arise).

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/
	https://github.com/gitster/git-htmldocs.git/

Release tarballs are available at:

[New Topics]

* jk/commit-graph-lazy-load-fallback (2026-05-18) 1 commit
 - commit: fall back to full read when maybe_tree is NULL

 The logic to lazy-load trees from the commit-graph has been made
 more robust by falling back to reading the commit object when
 the commit-graph is no longer available.

 Will merge to 'next'?

* jk/connect-service-enum (2026-05-18) 1 commit
 - connect: use "service" enum for "name" argument

 The "name" argument in git_connect() and related functions has been
 converted to a "service" enum to improve type safety and clarify its
 purpose.

 Will merge to 'next'.

* jk/sq-dequote-cleanup (2026-05-18) 3 commits
 - quote: simplify internals of dequoting
 - quote: drop sq_dequote_to_argv()
 - quote.h: bump strvec forward declaration to the top

 Code simplification.

 Will merge to 'next'.

* aj/stash-patch-optimize-temporary-index (2026-05-19) 1 commit
 - stash: reuse cached index entries in --patch temporary index

 "git stash -p" has been optimized by reusing cached index
 entries in its temporary index, avoiding unnecessary lstat()
 calls on unchanged files.
 source: <[email-masked]>

* tb/bitmap-build-performance (2026-05-19) 9 commits
 - pack-bitmap: build pseudo-merge bitmaps after regular bitmaps
 - pack-bitmap: remember pseudo-merge parents
 - pack-bitmap: sort bitmaps before XORing
 - pack-bitmap: cache object positions during fill
 - pack-bitmap: consolidate `find_object_pos()` success path
 - pack-bitmap: reuse stored selected bitmaps
 - pack-bitmap: check subtree bits before recursing
 - pack-bitmap: pass object position to `fill_bitmap_tree()`
 - Merge branch 'tb/pseudo-merge-bugfixes' into tb/bitmap-build-performance
 (this branch uses tb/pseudo-merge-bugfixes.)

 Reachability bitmap generation has been significantly optimized. By
 reordering tree traversal, caching object positions, and refining how
 pseudo-merge bitmaps are constructed, the performance of "git repack
 --write-midx-bitmaps" is improved, especially for large repositories
 and when using pseudo-merges.
