Honestly, I do not really care (yet); what you are talkng about is merely an addition to Documentation/SubmittingPatches, which is trivial. The content of the hook is much more important. If it has too many false positives, it is not worth even encouraging its use to less experienced ones, as they will have hard time to figure out which errors matter and which erros can be ignored. It will make contributing to the project harder, not easier. As I do not think (1) we would be able to do a good job reducing false positives without writing a full POSIX shell parser, and (2) we would want to be in the business of writing POSIX shell parser [*1*], I am somewhat skeptical. And if we cannot come up with a reliable hook in the first place, there isn't much point in discussing a policy to encourage such a hook, is it? [Footnote] *1* Is there a free one that is portable, perhaps written in either Perl or Python, to which we can easily plug our own logic? In order to catch basic errors, I think it is sufficient to tokenize the script into independent series of simple commands, even ignoring variable substitutions and evals, and just have a bunch of "we do not allow option X to command Y" rules (e.g. "no -i to sed", "the first argument must be 'git' for "test_must_fail"). -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
