test_description='Tests of cwd/prefix/worktree/gitdir setup in all cases'
. ./test-lib.sh
#
# A few rules for repo setup:
#
# 1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
# GIT_DIR.
#
# 2. .git file is relative to parent directory. .git file is basically
# symlink in disguise. The directory where .git file points to will
# become new git_dir.
#
# 3. core.worktree is relative to git_dir.
#
# 4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
# equivalent to GIT_WORK_TREE.
#
# 5. GIT_WORK_TREE/core.worktree is only effective if GIT_DIR is set
# Uneffective worktree settings should be warned.
#
# 6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
#
# 7. Effective core.worktree conflicts with core.bare
#
# 8. If GIT_DIR is set but neither worktree nor bare setting is given,
# original cwd becomes worktree.
#
# 9. If .git discovery is done inside a repo, the repo becomes a bare
# repo. .git discovery is performed if GIT_DIR is not set.
#
# 10. If no worktree is available, cwd remains unchanged, prefix is
# NULL.
#
# 11. When user's cwd is outside worktree, cwd remains unchanged,
# prefix is NULL.
