git not allowing 744 as permissions for a file

git not allowing 744 as permissions for a file

[Auriane Reverdell]

Hi,

git doesn't allow to add the execution permission on a file only for
the user. A chmod 744 on a file will transform into 755 when added to
git. This can potentially lead to security problems on certain
systems. Is there a way to fix that? I'll be happy to do so if
somebody shows me where to do it.

Auriane R.

No, there isn't.  Git tracks only whether the executable bit is set.
All file modes are either 644 or 755.

If you need the permissions or ownership on the file to be different,
you can do that by using a script to copy the files into another
location with the proper permissions or ownership instead of using the
copies in the repository.  For example, I do this with my dotfiles such
that the files have the correct permissions.
