t/chainlint: add more chainlint.pl self-tests During the development of chainlint.pl, numerous new self-tests were created to verify correct functioning beyond the checks already represented by the existing self-tests. The new checks fall into several categories: * behavior of the lexical analyzer for complex cases, such as line splicing, token pasting, entering and exiting string contexts inside and outside of test script bodies; for instance: test_expect_success 'title' ' x=$(echo "something" \| sed -e '\''s/\\/\\\\/g'\'' -e '\''s/[[/.^$]/\\&/g'\'' ' behavior of the parser for all compound grammatical constructs, such as `if...fi`, `case...esac`, `while...done`, `{...}`, etc., and for other legal shell grammatical constructs not covered by existing chainlint.sed self-tests, as well as complex cases, such as: OUT=$( ((large_git 1>&3) \| :) 3>&1 ) && * detection of problems, such as &&-chain breakage, from top-level to any depth since the existing self-tests do not cover any top-level context and only cover subshells one level deep due to limitations of chainlint.sed * address blind spots in chainlint.sed (such as not detecting a broken &&-chain on a one-line for-loop in a subshell[1]) which chainlint.pl correctly detects * real-world cases which tripped up chainlint.pl during its development [1]: https://lore.kernel.org/git/dce35a47012fecc6edc11c68e91dbb485c5bc36f.1661663880.git.gitgitgadget@gmail.com/ Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> 2022-09-01 00:29:52 +00:00			`# LINT: SQ-string Perl code fragment within SQ-string`
