What's cooking in git.git (Dec 2025, #08)

[Junio C Hamano <gitster@pobox.com>]

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).

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/

* yc/histogram-hunk-shift-fix (2025-12-06) 1 commit
 - xdiff: re-diff shifted change groups when using histogram algorithm

 The final clean-up phase of the diff output could turn the result of
 histogram diff algorithm suboptimal, which has been corrected.

* jk/parse-int (2025-11-30) 5 commits
 - fsck: use parse_unsigned_from_buf() for parsing timestamp
 - cache-tree: use parse_int_from_buf()
 - parse: add functions for parsing from non-string buffers
 - parse: prefer bool to int for boolean returns
 - Merge branch 'jk/asan-bonanza' into jk/parse-int

 Introduce a more robust way to parse a decimal integer stored in a
 piece of memory that is not necessarily terminated with NUL (which
 Asan strict-string-check complains even when use of strtol() is
 safe due to varified existence of whitespace after the digits).

 Expecting a reroll.

 Prepare test suite for Git for Windows that supports symbolic
 links.

 "git replay" is taught to drop commits that become empty (not the
 ones that are empty in the original).

 On hold, until the base topic gains consensus and stabilizes.

 - cleanup_path: force forward slashes on Windows

 "git config --list --global", unlike "git config --list", did not
 consult both of the two possible per-user sources of the
 configuration files, i.e. $HOME/.gitconfig and the XDG one, which
 has been corrected.

 "git add ':(exclude)foo.o'" is clearly a request not to add 'foo.o',
 but the command complained about listing an ignored path foo.o on
 the command line, which has been corrected.
