What's cooking in git.git (Mar 2026, #11)

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/

- doc: note that -L supports patch formatting and pickaxe options
- t4211: add tests for -L with standard diff options
- line-log: route -L output through the standard diff pipeline
- line-log: fix crash when combined with pickaxe options

The way the "git log -L<range>:<file>" feature is bolted onto the log/diff machinery is being reworked a bit to make the feature compatible with more diff options, like -S/G.

Needs review.

* jc/neuter-sideband-fixup (2026-03-05) 6 commits
(merged to 'next' on 2026-03-13 at 5a4098b0cd)
+ sideband: drop 'default' configuration
+ sideband: offer to configure sanitizing on a per-URL basis
+ sideband: add options to allow more control sequences to be passed through
+ sideband: do allow ANSI color sequences by default
+ sideband: introduce an "escape hatch" to allow control characters
+ sideband: mask control characters
(this branch is used by jc/neuter-sideband-post-3.0.)

Try to resurrect and reboot a stalled "avoid sending risky escape sequences taken from sideband to the terminal" topic by Dscho. The plan is to keep it in 'next' long enough to see if anybody screams with the "everything dropped except for ANSI color escape sequences" default.

Will keep in 'next' a bit longer than usual.

The final step, split from earlier attempt by Dscho, to loosen the sideband restriction for now and tighten later at Git v3.0 boundary.

On hold, until jc/neuter-sideband-fixup cooks long enough in 'next'. (this branch uses jc/neuter-sideband-fixup.)

The mechanism to avoid recursive lazy-fetch from promisor remotes was not propagated properly to child "git fetch" processes, which has been corrected.

"git format-patch --cover-letter" learns to use a simpler format instead of the traditional shortlog format to list its commits with a new --cover-letter-format option and format.commitListFormat configuration variable.

Waiting for the follow-on topic.

Need to step back and rethink how exit code should look like. cf. <[email protected]>

I don't have anything else to add to this series, so I'm fine with it being merged down.

Hm, I think this status is probably stale, as I've sent out that response already and don't plan to change anything for now. So from my perspective the patch is ready for next, but please let me know in case you have different expectations.

I'll have a look at v3 of this series series today.

Likewise, will try to find the time to do this today.

Thanks!

Patrick

Indeed. I am not convinced by the argument "64-bit compilers would not care if 32-bit part of the live code that it will optimize away is not -Werror clean", but we can merge it as-is and then deal with any fallout later, as it should be trivial to switch to conditional compilation (the triviality is why I suggested making the change now in the first place anyway).

Thanks.

Thanks.

As Toon said that the silent failure in case of "topic" instead of "main..topic" will be addressed in a separate series, I am fine with merging as is.

It looks good to me, and I think the v6 properly addresses the latest few small issues that were found. Previously Phillip also seemed OK with merging except for the issues that are now fixed.

I'll have to go back to list to find the original discussion to refresh my memory to know what "main..topic" vs "topic" is about, though X-<.

Thanks.

Sorry for not being explicit enough. BTW I just left another comment
on this (see https://lore.kernel.org/git/CAP8UFD3P2Gs0J1FNyKW2URwSEW4ZaTrVO7cM1V8sG+zzXctbhg@mail.gmail.com/).
