The parse-options library learned to auto-correct misspelled subcommand names. * js/parseopt-subcommand-autocorrection: doc: document autocorrect API parseopt: add tests for subcommand autocorrection parseopt: enable subcommand autocorrection for git-remote and git-notes parseopt: autocorrect mistyped subcommands autocorrect: provide config resolution API autocorrect: rename AUTOCORRECT_SHOW to AUTOCORRECT_HINT autocorrect: use mode and delay instead of magic numbers help: move tty check for autocorrection to autocorrect.c help: make autocorrect handling reusable parseopt: extract subcommand handling from parse_options_step()

Merge branch 'bc/rust-by-default' into jch

2026-04-17T04:27:19Z

Rust support is enabled by default (but still allows opting out) in some future version of Git. * bc/rust-by-default: Enable Rust by default Linux: link against libdl ci: install cargo on Alpine docs: update version with default Rust support

Merge branch 'ar/parallel-hooks' into jch

* ar/parallel-hooks: t1800: test SIGPIPE with parallel hooks hook: allow hook.jobs=-1 to use all available CPU cores hook: add hook..enabled switch hook: move is_known_hook() to hook.c for wider use hook: warn when hook..jobs is set hook: add per-event jobs config hook: add -j/--jobs option to git hook run hook: mark non-parallelizable hooks hook: allow pre-push parallel execution hook: allow parallel hook execution hook: parse the hook.jobs config config: add a repo_config_get_uint() helper repository: fix repo_init() memleak due to missing _clear()

hook: move is_known_hook() to hook.c for wider use

2026-04-10T14:58:54Z

Move is_known_hook() from builtin/hook.c (static) into hook.c and export it via hook.h so it can be reused. Make it return bool and the iterator `h` for clarity (iterate hooks). Both meson.build and the Makefile are updated to reflect that the header is now used by libgit, not the builtin sources. The next commit will use this to reject hook friendly-names that collide with known event names. Co-authored-by: Patrick Steinhardt Signed-off-by: Adrian Ratiu Signed-off-by: Junio C Hamano

Enable Rust by default

2026-04-10T00:25:36Z

Our breaking changes document says that we'll enable Rust by default in Git 2.54. Adjust the Makefile to switch the option from WITH_RUST to NO_RUST to enable it by default and update the help text accordingly. Similarly, for Meson, enable the option by default and do not automatically disable it if Cargo is missing, since the goal is to help users find where they are likely to have problems in the future. Update our CI tests to swap out the single Linux job with Rust to a single job without, both for Makefile and Meson. Similarly, update the Windows Makefile job to not use Rust, while the Meson job (which does not build with ci/lib.sh) will default to having it enabled. Move the check for Cargo in the Meson build because it is no longer needed in the main script. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

Tweak the build infrastructure by moving tools around. * ps/build-tweaks: meson: precompile "git-compat-util.h" meson: compile compatibility sources separately git-compat-util.h: move warning infra to prepare for PCHs builds: move build scripts into "tools/" contrib: move "update-unicode.sh" script into "tools/" contrib: move "coverage-diff.sh" script into "tools/" contrib: move "coccinelle/" directory into "tools/" Introduce new "tools/" directory

hook: reject unknown hook names in git-hook(1)

2026-03-25T21:00:48Z

Teach "git hook run" and "git hook list" to reject hook event names that are not recognized by Git. This helps catch typos such as "prereceive" when "pre-receive" was intended, since in 99% of the cases users want known (already-existing) hook names. The list of known hooks is derived from the generated hook-list.h (built from Documentation/githooks.adoc). This is why the Makefile is updated, so builtin/hook.c depends on hook-list.h. In meson the header is already a dependency for all builtins, no change required. The "--allow-unknown-hook-name" flag can be used to bypass this check.
