[4/4] t0000: consistently use single quotes for outer tests

Commit Message

Jeff King Jan. 28, 2021, 6:32 a.m. UTC

When we use the sub-test helpers, we end up defining one shell snippet
inside another shell snippet. So if we use single-quotes for the outer
snippet, we have to use double-quotes within the inner snippet (it's
included as here-doc within the outer snippet, but using a single quote
would end the outer snippet early). Or vice versa we can use double
quotes for the outer snippet, but then single quotes in the inner.

We have some of each in the script, and neither is wrong. But it would
be nice to be consistent unless there is a good reason not to. Using
single quotes for the outer script is preferable, because it requires
less metacharacter quoting overall. For example, in:

  test_expect_success 'outer' '
	run_sub_test_lib_test ...  <<-\EOF
		echo $foo &&
		test_expect_success "inner" "
			echo \$bar
		"
	EOF
  '

we need only quote inside "inner", but not inside "outer" or the
here-doc. Whereas if we flip them, we have to quote in both places:

  test_expect_success 'outer' "
	run_sub_test_lib_test ...  <<-\EOF
		echo \$foo &&
		test_expect_success 'inner' '
			echo \$bar
		'
	EOF
  "

The exception is when we need a literal single-quote in an expected
output here-doc. There we can either use outer double-quotes, or just
use ${SQ} within the doc. I chose the latter for consistency (within
this test, but also with other test scripts that face the same problem).

There is one other interesting case, which is some tests that do:

  test_expect_success ... "
	do_something --run='"'!3'"'
  "

This is rather confusing to read, but is correct. The outer script sees
'!3' in single-quotes, as does the eval'd snippet. This is perhaps being
overly cautious. In many interactive shells, an exclamation triggers
history expansion even inside double quotes, but that is not generally
true in non-interactive shells.

There's some conflicting information here. Commit 784ce03d55 (t4216:
avoid unnecessary subshell in test_bloom_filters_not_used, 2020-05-19)
reports it as a problem with OpenBSD 6.7's /bin/sh. However, we have
many instances in this script of prereqs like !LAZY_TRUE, which haven't
been a problem. I left them un-escaped here to test out this theory.
It's much nicer if we can not worry about this as a portability issue,
so it's worth knowing.
