PERTAIN_TOProblem

std::string_view becomes invalid after moving a std::string when the string uses SSO

PERTAIN_TOProblem

I have a class that holds a URL as a string, and then access to each of the parts of the URL is held as views into the original URL — my class move constructor. Outcome: calculating the views has a cost, but it's better to calculate it once than on each access.

PERTAIN_TOSolution

how to detect whether a given string is using SSO — take appropriate action in my class move constructor. Tension: view dataView to remain valid. Outcome: This fairly simple function works in practice.

PERTAIN_TORootCause

verify_token() splits the token. Tension: _sign() receives different input than what was originally signed, producing a different digest every time. Outcome: create_token() computes HMAC over raw JSON bytes.

PERTAIN_TOProblem

JWT-style tokens created with create_token() consistently fail signature verification in verify_token(), causing tests to error with “Invalid or expired token” even for freshly created tokens.
