[PATCH 00/42] repo setup test cases and fixes

[Nguyễn Thái Ngọc Duy]

I hope this is the last time setup_* functions need to be fixed. There
is still room for improvement though. Two comes to mind are:

 - warn users when GIT_WORK_TREE/core.worktree/core.bare is set but
   ignored
 - turn absolute path to relative where possible

This series includes setup coverage tests (180/376 fail). Then the fixes,
which bring down to zero failed test in the end. 02/42 describes the
rules. New rules are:

 - GIT_WORK_TREE is relative to user's cwd. This is how the code works
   until now (which also makes sense to me).

 - core.worktree won't override core.bare.

Documents may need updates. I'll do that later.


Nguyễn Thái Ngọc Duy (42):

Tests


  rev-parse: prints --git-dir relative to user's cwd

Indepdent fix, but is needed after setup_* rework because the new code
will set relative git_dir.


  Add git_config_early()
  Use git_config_early() instead of git_config() during repo setup

Cherry-picked from my old tp/setup series, needed to be able to check
core.{bare,worktree} early.


  Remove all logic from get_git_work_tree()

Break it some more.


  setup: clean up setup_bare_git_dir()
  setup: clean up setup_discovered_git_dir()
  setup: rework setup_explicit_git_dir()

setup_* rework.

  t1510: all failed tests are now fixed

All tests are passed.

+# 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,

[PATCH 35/42] rev-parse: prints --git-dir relative to user's cwd

[Nguyễn Thái Ngọc Duy]

git-rev-parse.txt does not say much about this. But I'm sure
git-sh-setup.sh wants "git rev-parse --git-dir" be relative to user's
cwd.

git_dir variable in environment.c on the other hand is relative to
git's cwd, not user's cwd. Convert the relative path (actualy by making it
absolute path) before printing out.

[PATCH 36/42] Add git_config_early()

[Nguyễn Thái Ngọc Duy]

This version of git_config() will be used during repository setup.
As a repository is being set up, $GIT_DIR is not nailed down yet,
git_pathdup() should not be used to get $GIT_DIR/config.

[PATCH 37/42] Use git_config_early() instead of git_config() during repo setup

[Nguyễn Thái Ngọc Duy]

When git_config() is called, either git_dir has already been set (by
$GIT_DIR env or set_git_dir()), or it will default git_dir to ".git".

git_config_early() gives setup functions more freedom because it does
not require git_dir. Give it a config path, it will happily examine
it.

[PATCH 41/42] setup: rework setup_explicit_git_dir()

[Nguyễn Thái Ngọc Duy]

This function is the most complex one among the three setup_*
functions because all GIT_DIR, GIT_WORK_TREE, core.worktree and
core.bare are involved.

Because core.worktree is only effective inside
setup_explicit_git_dir() and the extra code in setup_git_directory()
is to handle that. The extra code can now be retired.

Shouldn't the fixes come first (for bisectability?). It don't much
like the idea of the test suite being horribly broken for a whole
bunch of patches that someone might end up hitting while bisecting.

We don't usually use "I" in commit messages, was this meant for after
the triple dash, or does this commit message just need work?

Good point.  Ideally the tests would come first if the fixes are
contraversial, or be squashed with the fixes if neither is
contraversial, or after if the tests are contraversial but the fixes
are not.

For bisectability and clarity, the tests should use test_expect_failure
when they fail (like this patch series does) and change that to
test_expect_success in the patch that fixes them.

I don't know about this, do we really want to willingly break the test
suite (and fixing it later)? Perhaps we can review this as-is and then
squash the commits before they are merged to next so that there is no
breakage? We could even attach the original commits as notes :).

Squashing is no good in terms of readability when we look back in
history. Can git-bisect be taught that "there is breakage in this
segment of commits, consider the whole segment a single commit"?

I used "I" because I was not confident that this must be done this
way. Perhaps after we agree that all users of "git rev-parse
--git-dir" expect the same, commit message can be rewritten to reflect
that.

Yes, $(git rev-parse --git-dir) should be relative to the caller's
working directory, or else git-sh-setup in the ! "$NONGIT_OK" case
will fail, as you noticed.

Maybe this can be clarified?

The current behavior is often to print an absolute path rather than
a ../../etc string, but callers must be ready to accept a relative
path, too.  The most common output is ".git" (from the toplevel of
an ordinary work tree).

 OK. Take 2. I think it is bisectable this time. This replaces
 35-42 (the fixing part, no need to resend 34 unchanged patches). More notes
 on each patch.

This version of git_config() will be used during repository setup.
As a repository is being set up, $GIT_DIR is not nailed down yet,

[PATCH 4/9] Use git_config_early() instead of git_config() during repo setup

[Nguyễn Thái Ngọc Duy]

When git_config() is called, either git_dir has already been set (by
$GIT_DIR env or set_git_dir()), or it will default git_dir to ".git".

git_config_early() gives setup functions more freedom because it does
not require git_dir. Give it a config path, it will happily examine
it.

[PATCH 5/9] setup: limit get_git_work_tree()'s to explicit setup case only

[Nguyễn Thái Ngọc Duy]

get_git_work_tree() takes input as core.worktree, core.bare,
GIT_WORK_TREE and decides correct worktree setting.

Unfortunately it does not do its job well. core.worktree and
GIT_WORK_TREE should only be taken into account, if GIT_DIR is set
(which is handled by setup_explicit_git_dir). For other setup cases,
only core.bare matters.

Add a temporary variable setup_explicit to adjust get_git_work_tree()
behavior as such. This variable will be gone once setup_* rework is
done.

Also remove is_bare_repository_cfg check in set_git_work_tree() to
ease the rework. We are going to check for core.bare and core.worktree
early before setting worktree. For example, if core.bare is true, no
need to set worktree.

 I isolate setup_bare_git_dir and setup_discovered_git_dir from
 get_git_work_tree() with this patch. setup_explicit_git_dir will
 remove "startup_info->setup_explicit = 1", which means
 get_git_work_tree() can no longer affect setup_* even if all the
 logic is there.

[PATCH 7/9] setup: clean up setup_discovered_git_dir()

[Nguyễn Thái Ngọc Duy]

If core.bare is true, discard the discovered worktree, move back to
original cwd.

This change may set GIT_DIR env var to ".git" via set_git_dir(). This
bothers alias handling because handle_alias() does

1. prefix = setup_git_directory_gently(..)
2. look up alias
3. chdir(prefix)

After step 1, GIT_DIR may be set to ".git" (relative to worktree), but
step 3 moves cwd back to original cwd. When the next
setup_git_directory_gently() is called by run_builtin(), it will
mistakenly find ".git" in original cwd.

As a workaround, teach set_git_dir() not to set to
".git". setup_git_env() will default to ".git" later on. Alias
handling code will need more work later.

Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>

 The alias breakage is new. It should be fixed by calling setup_git_*
 only once. No "chdir(prefix)" any more. And that fix will be needed
 before we can turn more git_dir to relative path.

 But for now the workaround is enough, I think.

[PATCH 8/9] setup: rework setup_explicit_git_dir()

[Nguyễn Thái Ngọc Duy]

This function is the most complex one among the three setup_*
functions because all GIT_DIR, GIT_WORK_TREE, core.worktree and
core.bare are involved.

Because core.worktree is only effective inside
setup_explicit_git_dir() and the extra code in setup_git_directory()
is to handle that. The extra code can now be retired.

Also note that setup_explicit assignment is removed, worktree setting
is no longer decided by get_git_work_tree(). get_git_work_tree() will
be simplified in the next commit.

[PATCH 9/9] Remove all logic from get_git_work_tree()

[Nguyễn Thái Ngọc Duy]

This logic is now only used by cmd_init_db(). setup_* functions do not
rely on it any more. Move all the logic to cmd_init_db() and turn
get_git_work_tree() into a simple function.
