The setup code used to die when core.bare and core.worktree are set
inconsistently, even for commands that do not need working tree.
* jk/die-on-bogus-worktree-late:
setup_git_directory: delay core.bare/core.worktree errors
|

If both core.bare and core.worktree are set, we complain
about the bogus config and die. Dying is good, because it
avoids commands running and doing damage in a potentially
incorrect setup. But dying _there_ is bad, because it means
that commands which do not even care about the work tree
cannot run. This can make repairing the situation harder:
[setup]
$ git config core.bare true
$ git config core.worktree /some/path
[OK, expected.]
$ git status
fatal: core.bare and core.worktree do not make sense
[Hrm...]
$ git config --unset core.worktree
fatal: core.bare and core.worktree do not make sense
[Nope...]
$ git config --edit
fatal: core.bare and core.worktree do not make sense
[Gaaah.]
$ git help config
fatal: core.bare and core.worktree do not make sense
Instead, let's issue a warning about the bogus config when
we notice it (i.e., for all commands), but only die when the
command tries to use the work tree (by calling setup_work_tree).
So we now get:
$ git status
warning: core.bare and core.worktree do not make sense
fatal: unable to set up work tree using invalid config
$ git config --unset core.worktree
warning: core.bare and core.worktree do not make sense
We have to update t1510 to accomodate this; it uses
symbolic-ref to check whether the configuration works or
not, but of course that command does not use the working
tree. Instead, we switch it to use `git status`, as it
requires a work-tree, does not need any special setup, and
is read-only (so a failure will not adversely affect further
tests).
In addition, we add a new test that checks the desired
behavior (i.e., that running "git config" with the bogus
config does in fact work).

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.

Ordinarily, we would say "VAR=VAL command" to execute a tested
command with environment variable(s) set only for that command.
This however does not work if 'command' is a shell function (most
notably 'test_must_fail'); the result of the assignment is retained
and affects later commands.
To avoid this, we used to assign and export environment variables
and run such a test in a subshell, like so:
(
VAR=VAL && export VAR &&
test_must_fail git command to be tested
)
But with "env" utility, we should be able to say:
test_must_fail env VAR=VAL git command to be tested
which is much shorter and easier to read.

If an explicit GIT_DIR is given without a working tree, we
implicitly assume that the current working directory should
be used as the working tree. E.g.,:
GIT_DIR=/some/repo.git git status
would compare against the cwd.
Unfortunately, we fool this rule for sub-invocations of git
by setting GIT_DIR internally ourselves. For example:
git init foo
cd foo/.git
git status ;# fails, as we expect
git config alias.st status
git status ;# does not fail, but should
What happens is that we run setup_git_directory when doing
alias lookup (since we need to see the config), set GIT_DIR
as a result, and then leave GIT_WORK_TREE blank (because we
do not have one). Then when we actually run the status
command, we do setup_git_directory again, which sees our
explicit GIT_DIR and uses the cwd as an implicit worktree.
It's tempting to argue that we should be suppressing that
second invocation of setup_git_directory, as it could use
the values we already found in memory. However, the problem
still exists for sub-processes (e.g., if "git status" were
an external command).
You can see another example with the "--bare" option, which
sets GIT_DIR explicitly. For example:
git init foo
cd foo/.git
git status ;# fails
git --bare status ;# does NOT fail
We need some way of telling sub-processes "even though
GIT_DIR is set, do not use cwd as an implicit working tree".
We could do it by putting a special token into
GIT_WORK_TREE, but the obvious choice (an empty string) has
some portability problems.
Instead, we add a new boolean variable, GIT_IMPLICIT_WORK_TREE,
which suppresses the use of cwd as a working tree when
GIT_DIR is set. We trigger the new variable when we know we
are in a bare setting.
The variable is left intentionally undocumented, as this is
an internal detail (for now, anyway). If somebody comes up
with a good alternate use for it, and once we are confident
we have shaken any bugs out of it, we can consider promoting
it further.

Breaks in a test assertion's && chain can potentially hide failures from
earlier commands in the chain by adding " &&" at the end of line to the
commands that need them.

The original intention of --work-tree was to allow people to work in a
subdirectory of their working tree that does not have an embedded .git
directory. Because their working tree, which their $cwd was in, did not
have an embedded .git, they needed to use $GIT_DIR to specify where it is,
and because this meant there was no way to discover where the root level
of the working tree was, so we needed to add $GIT_WORK_TREE to tell git
where it was.
However, this facility has long been (mis)used by people's scripts to
start git from a working tree _with_ an embedded .git directory, let git
find .git directory, and then pretend as if an unrelated directory were
the associated working tree of the .git directory found by the discovery
process. It happens to work in simple cases, and is not worth causing
"regression" to these scripts.

New test helpers:
- setup_repo, to initialize a repository or gitfile pointing to a
repository, with core.bare and core.worktree set as specified;
- try_case, to run setup from a given directory and validate the
result, with GIT_DIR and GIT_WORK_TREE set as specified;
- try_repo, to initialize a repository and call "try_case" from the
toplevel and a subdirectory;
- run_wt_tests, to run a battery of tests that check for sane
behavior when GIT_WORK_TREE is set to various positions relative to
the .git dir and cwd.
Use these helpers to make the test shorter, less repetitive, and (one
hopes) easier to understand and modify.

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
hunk of the diff.

On some shells (like /usr/xpg4/bin/sh on Solaris), unset will exit
non-zero when passed the name of a variable that has not been set. Use
sane_unset instead so that the return value of unset can be ignored while
the && linkage of the test script can be preserved.

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.

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.
