@Fisiu is it possible to update git to v2.40.1?
And probably we can add git subtree as requested in #5726?

[Fisiu]

git bumped to 2.40.1, subtree included. Not sure if there is macro for make however @$(RUN) make works fine.

@hgy59, thanks for suggestions - all applied.

@Fisiu I have two more suggestions

---

There are some non-stripped binaries in the libexec/git-core/ folder. By adding the following lines to cross/git/PLIST, we can strip those and reduce the package size a little bit:

bin:libexec/git-core/git
bin:libexec/git-core/git-daemon
bin:libexec/git-core/git-http-backend
bin:libexec/git-core/git-http-fetch
bin:libexec/git-core/git-http-push
bin:libexec/git-core/git-imap-send
bin:libexec/git-core/git-remote-http
bin:libexec/git-core/git-sh-i18n--envsubst
bin:libexec/git-core/git-shell
bin:libexec/git-core/scalar

Another suggestion is to use hardlinks and remove the NO_INSTALL_HARDLINKS=1 option from the INSTALL_MAKE_OPTIONS. (i.e. to remove the declaration of INSTALL_MAKE_OPTIONS in cross/git/Makefile at all, as the remaining value is the default).
And to remove the patch 001-git-less-hardlinks.patch.
With hardlinks some binary files are installed as links and this shrinks the package size by about 15%.
I have tested git with hardlinks on DSM 6 and 7 and cannot find any issues. But I have no clue why the option to disable hardlinks was added to the early git package (at least since version 1.8.1.5 on 11.03.2013).
This suggestion is not fully approved (and I will have to test it with DSM 5.2 too).
What do you think about this?

@hgy59
Changes applied. Indeed, spk file size has been reduced by few MB. I did some initial testing on DSM 7.1 and spk with hardlinks seems to be working as intended.

@Fisiu is there any benefit of including gitweb in the package?

We intentionally removed this in #5035. It was required by our git-server package that is not maintained for a long time.
As we have a gitea package and Synology provides a git-server package, there is no reason to keep this piece of code in the package.

I copied one line to much from generated PLIST. Should be good now.
