Remove various redundant or obsolete code from the test_create_repo()
function, and split up its use in test-lib.sh from what tests need
from it.
This leave us with a pass-through wrapper for "git init" in
test-lib-functions.sh, in test-lib.sh we have the same, except for
needing to redirect stdout/stderr, and emitting an error ourselves if
it fails. We don't need to error() ourselves when test_create_repo()
is invoked, as the invocation will be a part of a test's "&&"-chain.
Everything below this paragraph is a detailed summary of the history
of test_create_repo() explaining why it's safe to remove the various
things it was doing:
1. "mkdir -p" isn't needed because "git init" itself will create
leading directories if needed.
2. Since we're now a simple wrapper for "git init" we don't need to
check that we have only one argument. If someone wants to run
"test_create_repo --bare x" that's OK.
3. We won't ever hit that "Cannot setup test environment"
error.
Checking the test environment sanity when doing "git init" dates
back to eea420693b (t0000: catch trivial pilot errors.,
2005-12-10) and 2ccd2027b0 (trivial: check, if t/trash directory
was successfully created, 2006-01-05).
We can also see it in another form a bit later in my own
0d314ce834 (test-lib: use subshell instead of cd $new && .. && cd
$old, 2010-08-30).
But since 2006f0adae (t/test-lib: make sure Git has already been
built, 2012-09-17) we already check if we have a built git
earlier.
The one thing this was testing after that 2012 change was that
we'd just built "git", but not "git-init", but since
3af4c7156c (tests: respect GIT_TEST_INSTALLED when initializing
repositories, 2018-11-12) we invoke "git", not "git-init".
So all of that's been checked already, and we don't need to
re-check it here.
4. We don't need to move .git/hooks out of the way.
That dates back to c09a69a83e (Disable hooks during tests.,
2005-10-16), since then hooks became disabled by default in
f98f8cbac0 (Ship sample hooks with .sample suffix, 2008-06-24).
So the hooks were already disabled by default, but as can be seen
from "mkdir .git/hooks" changes various tests needed to re-setup
that directory. Now they no longer do.
This makes us implicitly depend on the default hooks being
disabled, which is a good thing. If and when we'd have any
on-by-default hooks (I see no reason we ever would) we'd want to
see the subtle and not so subtle ways that would break the test
suite.
5. We don't need to "cd" to the "$repo" directory at all anymore.
In the code being removed here we both "cd"'d to the repository
before calling "init", and did so in a subshell.
It's not important to do either, so both of those can be
removed. We cd'd because this code grew from test-lib.sh code
where we'd have done so already, see eedf8f97e5 (Abstract
test_create_repo out for use in tests., 2006-02-17), and later
"cd"'d inside a subshell since 0d314ce834 to avoid having to keep
track of an "old pwd" variable to cd back after the setup.
Being in the repository directory made moving the hooks around
easier (we wouldn't have to fully qualify the path). Since we're
not moving the hooks per #4 above we don't need to "cd" for that
reason either.
6. We can drop the --template argument and instead rely on the
GIT_TEMPLATE_DIR set to the same path earlier in test-lib.sh. See
8683a45d66 (Introduce GIT_TEMPLATE_DIR, 2006-12-19)
7. We only needed that ">&3 2>&4" redirection when invoked from
test-lib.sh.
We could still invoke test_create_repo() there, but as the
invocation is now trivial and we don't have a good reason to use
test_create_repo() elsewhere let's call "git init" there
ourselves.
8. We didn't need to resolve "git" as
"${GIT_TEST_INSTALLED:-$GIT_EXEC_PATH}/git$X" in test_create_repo(),
even for the use of test-lib.sh
PATH is already set up in test-lib.sh to start with
GIT_TEST_INSTALLED and/or GIT_EXEC_PATH before
test_create_repo() (now "git init") is called.. So we can simply
run "git" and rely on the PATH lookup choosing the right
executable.
