[PATCH 00/34] repo setup test cases

From: Nguyễn Thái Ngọc Duy <hidden>
Date: 2016-06-15 22:49:55

A complete series after the WIP [1]. The rules are bent a bit, see 2/34.

178/376 test cases fail, but mostly because GIT_DIR=.git-file is
not supported. I'll send a bandage series shortly that will bring the
number of failed test cases to 20.

 It's not perfect. "setup: " lines won't always appear. That can be
 done once setup code is cleaned up a bit.

+#    GIT_DIR.
+#
+# 2. .git file is relative to git_dir. .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,

[PATCH 2/7] unset: discard GIT_WORK_TREE if GIT_DIR is not set

From: Nguyễn Thái Ngọc Duy <hidden>
Date: 2016-06-15 22:49:55

GIT_WORK_TREE can only be used together with GIT_DIR. Unfortunately
get_git_work_tree() checks that env variable unconditionally. As a
work around, discard the variable.

Now that core.worktree can only be effective inside
setup_explicit_git_dir, move the code up from setup_git_directory().

This is not completely followed in my tests. If .git is a true
symlink, its link is relative to .git itself. When .git is a file, it
would be more difficult to calculate path relative to .git (you can't
chdir to a file). In my tests, the link is relative to .git's parent
directory, not .git.

I'm not sure I understand:

 git init repo
 cd repo
 mv .git .git.real
 ln -s .git.real .git

The path ".git.real" is relative to "repo/", not "repo/.git/", no?
 
In other words, I don't you think you have to worry --- the test

In my tests, the link is relative to .git's parent
directory, not .git.

seems right.

Ah, ok. I was confused after writing all those tests.
