Hello If git commit executes .git/hooks/post-commit it will pass GIT_DIR env variable to the script. However, if hooksPath is set in $HOME/.gitconfig, git commit executes hooksPath/post-commit without passing GIT_DIR env variable to the script.
Expected behavior: GIT_DIR is passed to hooksPath/post-commit
Actual behavior: GIT_DIR isn't passed to hooksPath/post-commit
Please run the attached shell script in an empty directory to
reproduce this issue. The script is using strace to determine whether
GIT_DIR is passed to the hook script. The script will run "git gui":
the user is expected to simply commit changes from the gui and then
close the gui for the script to finish. The script is exploiting the
fact that (currently) command-line "git commit" and graphical "git
gui" commit are invoking different commit hooks.
Script output:
- !!! missing GIT_DIR in git-commit.strace
- execve(".git/hooks/post-commit", [... "GIT_DIR=.git" ...
$ cat ~/.gitconfig
[core]
hooksPath = /home/atom/dev/git-hooks
git version 2.21.0
Sincerely
Jan
