The '!SANITIZE_LEAK' prerequisite added in 956d2e4639 (tests: add a
test mode for SANITIZE=leak, run it in CI, 2021-09-23) has been used
in various tests to skip individual tests in otherwise leak-free
tests.
Let's change the cases that have become leak-free since then to run
under SANITIZE=leak.

Change some of the patterns in the test suite where we were hiding the
exit code from "git" by invoking it in a sub-shell within a "test"
expression to use temporary files and test_cmp instead.
These are not all the occurrences of this anti-pattern, but these in
particular hid issues where LSAN was dying, and I'd thus marked these
tests as passing under the linux-leaks CI job in past commits with
"TEST_PASSES_SANITIZE_LEAK=true". Let's deal with that by either
removing that marking, or skipping specific tests under
!SANITIZE_LEAK.

TEST_PASSES_SANITIZE_LEAK=true as passing when git is compiled with
SANITIZE=leak.
They'll now be listed as running under the

Carefully excluding t1309, which sees independent development elsewhere
at the time of writing, we transition above-mentioned tests to the
default branch name `main`. This trick was performed via
$ (cd t &&
sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \
-e 's/Master/Main/g' -e 's/naster/nain/g' -- t[01]*.sh &&
git checkout HEAD -- t1309\*)
Note that t5533 contains a variation of the name `master` (`naster`)
that we rename here, too.
This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main`
for those tests.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \
t/t0027-auto-crlf.sh t/t0060-path-utils.sh \
t/t1011-read-tree-sparse-checkout.sh \

We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' t/t980[0167]*.sh t/t9811*.sh

This ancient test script does a lot of manual checking of
test conditions with "if" blocks. We can simplify this
by relying on helpers like test_must_fail.
Note that a failing "grep" call here won't produce any
verbose output, but that's OK. These days we rely on "-x" to
tell us about such commands. And in addition, these greps
are soon to be converted to test_i18ngrep (which is itself
soon learning to be more verbose).

d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like
$GIT_DIR, 2015-06-26) attempted to work around a glitch in alias
handling by overwriting GIT_WORK_TREE environment variable to
affect subprocesses when set_git_work_tree() gets called, which
resulted in a rather unpleasant regression to "clone" and "init".
Try to address the same issue by always restoring the environment
and respawning the real underlying command when handling alias.

git.c: make sure we do not leak GIT_* to alias scripts
setup.c: re-fix d95138e (setup: set env $GIT_WORK_TREE when ..
git.c: make it clear save_env() is for alias handling only
An earlier change in 2.5.x-era broke users' hooks and aliases by
exporting GIT_WORK_TREE to point at the root of the working tree,
interfering when they tried to use a different working tree without
setting GIT_WORK_TREE environment themselves.
* nd/stop-setenv-work-tree:
Revert "setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR"
Commit d95138e [1] attempted to fix a .git file problem by
setting GIT_WORK_TREE whenever GIT_DIR is set. It sounded harmless
because we handle GIT_DIR and GIT_WORK_TREE side by side for most
commands, with two exceptions: git-init and git-clone.
"git clone" is not happy with d95138e. This command ignores GIT_DIR
but respects GIT_WORK_TREE [2] [3] which means it used to run fine
from a hook, where GIT_DIR was set but GIT_WORK_TREE was not (*).
With d95138e, GIT_WORK_TREE is set all the time and git-clone
interprets that as "I give you order to put the worktree here",
usually against the user's intention.
The solution in d95138e is reverted earlier, and instead we reuse
the solution from c056261 [4]. It fixed another setup-messed-
up-by-alias by saving and restoring env and spawning a new process,
but for git-clone and git-init only.
Now we conclude that setup-messed-up-by-alias is always evil. So the
env restoration is done for _all_ commands, including external ones,
whenever aliases are involved. It fixes what d95138e tried to fix,
without upsetting git-clone-inside-hooks.
The test from d95138e remains to verify it's not broken by this. A new
test is added to make sure git-clone-inside-hooks remains happy.
(*) GIT_WORK_TREE was not set _most of the time_. In some cases
GIT_WORK_TREE is set and git-clone will behave differently. The
use of GIT_WORK_TREE to direct git-clone to put work tree
elsewhere looks like a mistake because it causes surprises this
way. But that's a separate story.

Strict mode is about not guessing where .git is. If the user points to a
.git file, we know exactly where the target .git dir will be. This makes
it possible to serve .git files as repository on the server side.
This may be needed even in local clone case because transport.c code
uses upload-pack for fetching remote refs. But right now the
clone/transport code goes with non-strict.

In the test case, we run setup_git_dir_gently() the first time to read
$GIT_DIR/config so that we can resolve aliases. We'll enter
setup_discovered_git_dir() and may or may not call set_git_dir() near
the end of the function, depending on whether the detected git dir is
".git" or not. This set_git_dir() will set env var $GIT_DIR.
For normal repo, git dir detected via setup_discovered_git_dir() will be
".git", and set_git_dir() is not called. If .git file is used however,
the git dir can't be ".git" and set_git_dir() is called and $GIT_DIR
set. This is the key of this problem.
If we expand an alias (or autocorrect command names), then
setup_git_dir_gently() is run the second time. If $GIT_DIR is not set in
the first run, we run the same setup_discovered_git_dir() as before.
Nothing to see. If it is, however, we'll enter setup_explicit_git_dir()
this time.
This is where the "fun" is. If $GIT_WORK_TREE is not set but
$GIT_DIR is, you are supposed to be at the root level of the
worktree. But if you are in a subdir "foo/bar" (real worktree's top
is "foo"), this rule bites you: your detected worktree is now
"foo/bar", even though the first run correctly detected worktree as
"foo". You get "internal error: work tree has already been set" as a
result.
Bottom line is, when $GIT_DIR is set, $GIT_WORK_TREE should be set too
unless there's no work tree. But setting $GIT_WORK_TREE inside
set_git_dir() may backfire. We don't know at that point if work tree is
already configured by the caller. So set it when work tree is
detected. It does not harm if $GIT_WORK_TREE is set while $GIT_DIR is
not.

We try to avoid using the "-q" or "-e" options, as they are
largely useless, as explained in aadbe44f.
There is one exception for "-e" here, which is in t7701 used
to produce an "or" of patterns. This can be rewritten as an
egrep pattern.
This patch also removes use of "grep -F" in favor of the
more widely available "fgrep".
