I have the following Differential
This check checks function Cognitive Complexity metric, and flags
the functions with Cognitive Complexity exceeding the configured limit.
The default limit is `25`, same as in 'upstream'.
The metric is implemented as per [[ https://www.sonarsource.com/docs/
CognitiveComplexity.pdf | COGNITIVE COMPLEXITY by SonarSource ]] specification
version 1.2 (19 April 2017), with two notable exceptions:
* `preprocessor conditionals` (`#ifdef`, `#if`, `#elif`, `#else`, `#endif`)
are not accounted for.
Could be done. Currently, upstream does not account for them either.
* `each method in a recursion cycle` is not accounted for.
It can't be fully implemented, because cross-translational-unit analysis
would be needed, which is not possible in clang-tidy.
Thus, at least right now, i completely avoided implementing it.
As you can see, the implementation is based on a specification.
That Differential was created on 17 Aug, so ~50 days ago. In all this time,
there has been basically no feedback. Mid-September, thanks to Aaron Ballman,
the first review was done by Jonas Toth. Thanks to both of them!
After that, the code owner, Alexander Kornienko, has left a short message
questioning the legal status of that code
In my reply https://reviews.llvm.org/D36836#877642 i have shared the email
exchange which i believe supports my view that it is okay to have this in
LLVM. Since then, there has been no feedback.
Questions that i'd love to get addressed by this mail
* Am i doing something wrong?
* Am i, as not a lawyer, wrong in my view about the code status?
* Can somebody please review that code?
