bug when combined with etckeeper

I am running:

Linux  4.18.12-arch1-1-ARCH #1 SMP PREEMPT Thu Oct 4 01:01:27 UTC 2018 x86_64 GNU/Linux

git version 2.19.1

etckeeper Version: 1.18.8

I ran into a strange bug. In the following script the commit at the end will fail with: 

Note that there is no .gitignore file and no `.etckeeper` file in the repository, there is nothing in .git/exclude. There is no `core.excludesFile`, not locally, global, nor system. There are no userwide or systemwide ignore files. In fact there is not a single text file on my system which matches the regex '^\.etckeeper'. 

Also `git check-ignore .etckeeper` returns exit status 1. Thus I conclude that something isn't right. I don't know where the exclude rule comes from...

It works as expected if the `-a` option is not used on `git commit`.

I have not found any hints in the scripts from the etckeeper package that might explain this.

#------------------------------------------------ #! /usr/bin/bash

rm -rf gitignorebug

mkdir gitignorebug

cd gitignorebug

git init

git config --local user.name "git bug" git config --local user.email "git@bug.com"

touch file

git add file

git commit -am"add file" #---------------------------------------------------

Thank you for looking into it.

That's weird. Do you have any git-related environment variables set? Or anything in your config that might be pointing git to an alternate repository or working tree?

Try:

  env | grep GIT

and:

  git config --list --show-origin

/etc/.git/hooks/pre-commit is installed by etckeeper and runs etckeeper pre-commit, which deals with /etc/.etckeeper, including running "git add .etckeeper". Why that file would match a gitignore seems much less important than why git would run that hook in an entirely different git repository.

       core.hooksPath
           By default Git will look for your hooks in the $GIT_DIR/hooks
           directory. Set this to different path, e.g.  /etc/git/hooks, and Git
           will try to find your hooks in that directory, e.g.
           /etc/git/hooks/pre-receive instead of in $GIT_DIR/hooks/pre-receive.

Hmm, the example "/etc/git/hooks" there is very similar to the "/etc/.git/hooks" used by etckeeper. So my guess is you have core.hooksPath set globally.

Ok,

my bad. I had a global pre-commit hook which had a lingering etckeeper command for another repository.

Not quite sure why it only runs when commit has the '-a' option...

Thanks for pointing to the hooks possibility.
