Are we sure this is safe?

According to the documentation (emphasis mine):

The msg is typically NULL-terminated string of length len.

@mscdex Currently, this is always true, yes, and I think changing this would have to be considered a breaking change on the nghttp2 side

Non-blocking naive questions: Can we/should we add a test? A lint rule? An assertion or other check/confirmation of NULL-termination?

Can we/should we add a test?

I would not add a test for specific debugging statements.

A lint rule?

That would be great, but it might be quite a bit of effort.

An assertion or other check/confirmation of NULL-termination?

I don’t see any issue with adding DCHECK_LE(strlen(message), len);.
