This repository contains some files which have the same name on a case-insensitive filesystem (the default in Windows and OS X), which makes it impossible to check out cleanly.
SAME and same have identical content. DIFFERENT and different do not.
Git's response can be a little confusing. Cloning this repo on OS X checks out the following:
$ ls
README.md different same
Git thinks that DIFFERENT has changed, but doesn't notice that SAME doesn't
exist anymore:
$ git diff --stat
DIFFERENT | 2 +-
1 file changed, 1 insertion(+), 1 deletion(-)
And each time you try a git reset, Git toggles between deciding whether DIFFERENT
or different has problems:
$ git reset --hard -q && git diff --stat
different | 2 +-
1 file changed, 1 insertion(+), 1 deletion(-)
$ git reset --hard -q && git diff --stat
DIFFERENT | 2 +-
1 file changed, 1 insertion(+), 1 deletion(-)
This might seem like a weird edge case, but it has caught me out before. Don't
clone your Linux repositories onto a Mac and expect them to work when the
folder is synced to a Linux Vagrant. Or, if you do, make sure your Linux
repositories don't do insane things like contain both HTML.pm and html.pm,
or you will get different errors depending on how many Git commands you run
between tests.
