Ooh, good catch. This change fixes issues with ‘tests/git.scm’, is thatcorrect?
The ‘GIT_’ environment variables are honored by Git itself, not bylibgit2/Guile-Git, right?
Can we avoid setting HOME and XDG_CONFIG_HOME?
Perhaps these variables should all be set in ‘test-env’ along with theirfriends, for consistency?
Last, if we end up keeping ‘tests/fake-home’, make sure to also add itto ‘EXTRA_DIST’ in ‘Makefile.am’.
Could you send an updated patch?
Thanks for addressing it, and sorry for the loooong delay!
Ludo’.

Create a fake home in tests with a gitconfig so that the user configurationdoes not get picked up.I investigated how to solve this best, but git only respects HOME for thecommands we are using.Also note that this does not affect libraries, only the git cli, as librariesdo not use the environment variables.

As discussed on IRC yesterday (?), we can arrange to move thesevariables directly in (guix tests git), which is the only place where‘git’ is invoked. That way, it can’t possibly interfere with other usesof HOME, etc.
WDYT of something like the patch below?
Thanks,Ludo’.
