Pull request overview
This PR hardens scripts/top-complexity by avoiding shell-invoked pipelines/backticks and instead using list-form open(..., "-|", ...) to run git ls-files and pmccabe more safely.
Changes:
- Replace
open(F, "git ls-files ... |")with list-formopen(my $git, "-|", "git", "ls-files", ...). - Replace backticks execution of
pmccabewith list-formopen(my $pmc, "-|", $pmccabe, @files). - Explicitly close the new pipe filehandles.
