Using 'test_must_be_empty' is preferable to '! test -s', because it
gives a helpful error message if the given file is unexpectedly not
empty, while the latter remains completely silent. Furthermore, it
also catches cases when the given file unexpectedly does not exist at
all.
This patch was basically created by:
sed -i -e 's/! test -s/test_must_be_empty/' t[0-9]*.sh
with the following notable exceptions:
- The '! test -s' check in '.gitmodules ignore=dirty suppresses
submodules with untracked content' in 't7508-status.sh' is left
as-is, because it's bogus and, therefore, it's subject of a
dedicated patch.
- The '! test -s' checks in 't9131-git-svn-empty-symlink.sh' and
't9135-git-svn-moved-branch-empty-file.sh' are immediately
preceeded by a 'test -f' to ensure that the files exist in the
first place. 'test_must_be_empty' ensures that as well, so those
'test -f' commands are removed as well.

Commit f57f37e2e1 (files-backend: remove the use of
git_path(), 2017-03-26) introduced a regression when a
relative $GIT_DIR is used in a working tree:
- when we initialize the ref backend, we make a copy of
get_git_dir(), which may be relative
- later, we may call setup_work_tree() and chdir to the
root of the working tree
- further calls to the ref code will use the stored git
directory, but relative paths will now point to the
wrong place
The new test in t1501 demonstrates one such instance (the
bug causes us to write the ref update to the nonsense
"relative/relative/.git").
Since setup_work_tree() now uses chdir_notify, we can just
ask it update our relative paths when necessary.

In 4ac9006f83 (real_path: have callers use real_pathdup and
strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path())
pattern to use real_pathdup() directly.
The problem with this change is that real_path() calls
strbuf_realpath() with die_on_error = 1 while real_pathdup() calls
it with die_on_error = 0. Meaning that in cases where real_path()
causes Git to die() with an error message, real_pathdup() is silent
and returns NULL instead.
The callers, however, are ill-prepared for that change, as they expect
the return value to be non-NULL (and otherwise the function died
with an appropriate error message).
Fix this by extending real_pathdup()'s signature to accept the
die_on_error flag and simply pass it through to strbuf_realpath(),
and then adjust all callers after a careful audit whether they would
handle NULLs well.

"Work tree" or "working tree" is the name of a checked out tree,
"worktree" the name of the command which manages several working trees.
The naming of tests mixes these two, currently:
$ls t/*worktree*
t/t1501-worktree.sh
t/t1509-root-worktree.sh
t/t2025-worktree-add.sh
t/t2026-worktree-prune.sh
t/t2027-worktree-list.sh
t/t2104-update-index-skip-worktree.sh
t/t3320-notes-merge-worktrees.sh
t/t7011-skip-worktree-reading.sh
t/t7012-skip-worktree-writing.sh
t/t7409-submodule-detached-worktree.sh
$grep -l "git worktree" t/*.sh

t/t2027-worktree-list.sh
t/t3320-notes-merge-worktrees.sh
t/t7410-submodule-checkout-to.sh
Rename t1501, t1509 and t7409 to make it clear on first glance that they
test work tree related behavior, rather than the worktree command.
t2104, t7011 and t7012 are about the "skip-worktree" flag so that their

The repo setup procedure is updated to detect $GIT_DIR/commondir and
set $GIT_COMMON_DIR properly.
The core.worktree is ignored when $GIT_COMMON_DIR is set. This is
because the config file is shared in multi-checkout setup, but
checkout directories _are_ different. Making core.worktree effective
in all checkouts mean it's back to a single checkout.

On Windows, bash stores absolute path names in shell variables in POSIX
format that begins with a slash, rather than in drive-letter format; such
a value is converted to the latter format when it is passed to a non-MSYS
program such as git.
When an expected test value is constructed, it must contain the value that
will be produced by git, which will be in the drive-letter format. But
TRASH_DIRECTORY is in POSIX format. Fix this by using $(pwd), which
produces drive-letter format since 4114156a (Tests on Windows: $(pwd) must
return Windows-style paths).
The change in t1510 is a straight seach-and-replace, except for the first

When setup_work_tree() is called, it moves cwd to $GIT_WORK_TREE and
makes internal copy of $GIT_WORK_TREE absolute. The environt variable,
if set by user, remains unchanged. If the variable is relative, it is
no longer correct because its base dir has changed.
Instead of making $GIT_WORK_TREE absolute too, we just say "." and let
subsequent git processes handle it.

Tweak the style of these tests to make them easier to read.
- Replace test_rev_parse() which produced multiple mini-tests with a
simple function that can be used with the test body.
- Combine multiple mini-tests into larger chunks that are easier
to read.
- Do not hard-code object IDs. We may use a different hash some day.
- Use test_cmp in preference to the test builtin. The former
produces useful output when tests are run with the "-v" option.
- Guard all test code with test_expect_success. This makes it much
easier to visually scan through the test and find code of interest.
- Use subshells to make the current directory easier to track.
Outside of any subshell, the current directory is always
$TEST_DIRECTORY now.
Also add a new test demonstrating a possible bug noticed in the
process of cleaning up: “git rev-parse --show-prefix” leaves out
the trailing newline after an empty prefix when cwd is at the
toplevel of the work tree.

The function takes two paths, an early part of abs is supposed to match
base; otherwise abs is not a path under base and the function returns the
full path of abs. The caller can easily confuse the implementation by
giving duplicated and needless slashes in these path arguments.

A follow-up fix (squashed) is by Hannes.

If a command is run with an absolute path as a pathspec inside a bare
repository, e.g. "rev-list HEAD -- /home", the code tried to run strlen()
on NULL, which is the result of get_git_work_tree(), and segfaulted. It
should just fail instead.
Currently the function returns NULL even inside .git/ in a repository
with a work tree, but that is a separate issue.

Commit 72183cb2 (Fix gitdir detection when in subdir of
gitdir, 2009-01-16) added a test to 't1501-worktree' to check the
behaviour of 'git rev-parse --git-dir' in a special case. However,
t1501 is about testing separate work tree setups, and not about basic
'rev-parse' functionality, which is tested in t1500-rev-parse.
Therefore, this patch moves that test to t1500.

If the current working directory is a subdirectory of the gitdir (e.g.
<repo>/.git/refs/), then setup_git_directory_gently() will climb its
parent directories until it finds itself in a gitdir. However, no
matter how many parent directories it climbs, it sets
'GIT_DIR_ENVIRONMENT' to ".", which is obviously wrong.
This behaviour affected at least 'git rev-parse --git-dir' and hence
caused some errors in bash completion (e.g. customized command prompt
when on a detached head and completion of refs).
To fix this, we set the absolute path of the found gitdir instead.

There is one exception for "-e" here, which is in t7701 used

This fixes "git diff", "git diff-files" and "git diff-index" to work
correctly under worktree setup. Because diff* family works in many modes
and not all of them require worktree, Junio made a nice summary
(with a little modification from me):
* diff-files is about comparing with work tree, so it obviously needs a
work tree;
* diff-index also does, except "diff-index --cached" or "diff --cached TREE"
* no-index is about random files outside git context, so it obviously
doesn't need any work tree;
* comparing two (or more) trees doesn't;
* comparing two blobs doesn't;
* comparing a blob with a random file doesn't;

There are a few programs, such as config and diff, which allow running
without a git repository. Therefore, they have to call
setup_git_directory_gently().
However, when GIT_DIR and GIT_WORK_TREE were set, and the current

setup_git_directory_gently() would return a bogus NULL prefix.

The old version of work-tree support was an unholy mess, barely readable,
and not to the point.
For example, why do you have to provide a worktree, when it is not used?
As in "git status". Now it works.
Another riddle was: if you can have work trees inside the git dir, why
are some programs complaining that they need a work tree?
IOW it is allowed to call
$ git --git-dir=../ --work-tree=. bla
when you really want to. In this case, you are both in the git directory
and in the working tree. So, programs have to actually test for the right
thing, namely if they are inside a working tree, and not if they are
inside a git directory.
Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was
specified, unless there is a repository in the current working directory.
It does now.
The logic to determine if a repository is bare, or has a work tree
(tertium non datur), is this:
--work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true,
which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR
ends in /.git, which overrides the directory in which .git/ was found.
In related news, a long standing bug was fixed: when in .git/bla/x.git/,
which is a bare repository, git formerly assumed ../.. to be the
appropriate git dir. This problem was reported by Shawn Pearce to have
caused much pain, where a colleague mistakenly ran "git init" in "/" a
long time ago, and bare repositories just would not work.
