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.

Merge branch 'ps/upload-pack-buffer-more-writes'

2026-03-24T19:31:34Z

Reduce system overhead "git upload-pack" spends on relaying "git pack-objects" output to the "git fetch" running on the other end of the connection. * ps/upload-pack-buffer-more-writes: builtin/pack-objects: reduce lock contention when writing packfile data csum-file: drop `hashfd_throughput()` csum-file: introduce `hashfd_ext()` sideband: use writev(3p) to send pktlines wrapper: introduce writev(3p) wrappers compat/posix: introduce writev(3p) wrapper upload-pack: reduce lock contention when writing packfile data upload-pack: prefer flushing data over sending keepalive upload-pack: adapt keepalives based on buffering upload-pack: fix debug statement when flushing packfile data

builds: move build scripts into "tools/"

2026-03-19T13:40:09Z

We have a bunch of scripts used by our different build systems that are all located in the top-level directory. Now that we have introduced the new "tools/" directory though we have a better home for them. Move the scripts into the "tools/" directory.

contrib: move "coccinelle/" directory into "tools/"

2026-03-19T13:40:08Z

The Coccinelle tool is an ingrained part of our build infrastructure. It is executed by our CI to detect antipatterns and is used to detect misuses of certain interfaces. It's presence in "contrib/" is thus rather misleading. Promote the configuration into the new "tools/" directory. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

Introduce new "tools/" directory

2026-03-19T13:40:08Z

According to its readme, the "contrib/" directory's main intent is to collect stuff that is not an official part of Git, either because it is too specialized or because it is still considered experimental. The reality tells a bit of a different story though: while it _does_ contain such things, it also contains other things: - Our credential helpers, which are being distributed by many packagers nowadays and which can be considered "stable". - A bunch of tooling that relates to our build and test infrastructure. Especially the second category is somewhat of a sore spot. You really wouldn't expect build-related tooling to be considered an optional part of Git. Quite the opposite. Create a new top-level "tools/" directory to fix this discrepancy. This directory will contain all kind of tools that are related to our build infrastructure and that Git developers are likely to use day to day. For now, this directory doesn't contain anything yet except for a readme and a Meson skeleton. This will change in subsequent commits. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

compat/posix: introduce writev(3p) wrapper

2026-03-13T15:54:14Z

In a subsequent commit we're going to add the first caller to writev(3p). Introduce a compatibility wrapper for this syscall that we can use on systems that don't have this syscall. The syscall exists on modern Unixes like Linux and macOS, and seemingly even for NonStop according to [1]. It doesn't seem to exist on Windows though.
