> Documenting the behavior does not automatically excuse the behavior. It's a standard, and I'm citing the standard. The non-reentrant behavior doesn't need to be "excused", it is correct! If a microcontroller used a different bit than you expected it to for something, would the documentation need to be "excused" for "disagreeing" with you? That's how absurd what you're saying here sounds. > What people are arguing is that the specification should be improved That would be more reasonable, but that's not the argument. They're saying the standard is wrong. Standards can't be wrong, they're tautological. All that can be wrong is the programmer's understanding of them.

If your point is "the standard is correct as judged by the standard" your point is accurate and meaningless.

  Worse than that, it means that standards shouldn't be changed (e.g. to improve them): because the changed standard would be different from the standard and that would make it wrong by, well, being different from the standard! I've actually heard a similar argument about moral systems, about why the debater should not change his moral beliefs: it would be morally wrong for him to do that, you see, because then he'd then consider some things he currently considers morally right to be morally wrong and vice versa. Probably completely coincidentally, that debater was not a very nice person to talk to.

    > it means that standards shouldn't be changed (e.g. to improve them) I think it's more nuanced than that. It means standards shouldn't be changed in a way that breaks backward compatibility. That seems like an important feature of any standard. Nobody is saying standards shouldn't be improved.

I personally do not possess enough of mental flexibility to believe simultaneously both that "the standard is not wrong, it can not possibly be wrong" and that "the standard should be improved". And how do you improve standards anyway, without breaking compatibility? Making a previously thread-safe function non-thread-safe is an incompatible change: the clients relied on the thread-safety but new implementations won't provide it. Making a previously non-thread-safe function thread-safe is an incompatible change: the clients would rely on the thread-safety but old implementations don't provide it. And adding a new function to the standard is an undue burden on the implementers, and for almost no value since no client uses that function yet, and they won't for years because they want to keep backward compatibility with existing implementations.

I'm not the one saying that a standard cannot possibly be wrong. However, it is entirely coherent to say that a standard is not wrong and yet there is still room for it to be improved. "Not ideal" isn't the same as "wrong". > And how do you improve standards anyway, without breaking compatibility? Lots of ways, depending on what you think should be improved. In this case, you can improve it by adding a new set of functions that behave as you wish rather than altering the old functions in an incompatible way. If it's not possible to improve a standard without maintaining backward compatibility, then the solution is to introduce a new standard entirely. One of the main points of even having a standard is that you can rely on it, and things you make that adhere to it will continue to work into the future.
