Yeah, that makes sense (and is what I took away from the existing rule in CodingGuidelines, but I agree what is there is not very rigorous). > Optionally, > > - A C file must include only one of "git-compat-util.h", "cache.h" > or "builtin.h"; e.g. if you include "builtin.h", do not include > the other two, but it can consider what is availble in "cache.h" > available to it. > > Thoughts?

Not because I don't agree with it, but because I do not know that we want to get into the business of laying out every minute detail and implication. The CodingGuidelines document is meant to be guidelines, and I do not want to see arguments like "well, the guidelines do not explicitly _disallow_ this, so you must accept it or add something to the guideline". That is a waste of everybody's time. A general philosophy + good taste (from the submitter and the maintainer) should ideally be enough. And hopefully would stop a torrent of "but this file doesn't conform to the letter of CodingGuidelines!". Maybe it does not, but if there is no tangible benefit besides blindly following some rules, it is not worth the precious time of developers. Which isn't to say we shouldn't clarify the document when need be. But I think what I quoted at the top already is probably a good improvement over what is there. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
