Research direction
Start with rules/A15-4-4/MissingNoExcept.ql and the A15-4-4 example in the issue, then inspect how the generated MissingNoExcept.bqrs result treats string.append. Done means the rule no longer suggests noexcept for functions whose calls may implicitly throw std::bad_alloc, while preserving the existing behavior for genuinely non-throwing functions.
Written by the indexing model from the issue text.
Description
Affected rules
- A15-4-4
Description
A15-4-4/MissingNoExcept.ql flags functions which are not noexcept when no exception is explicitly thrown by them (or the functions they call). Unfortunately, this doesn't take into a account the fact that std::bad_alloc can be implicitly thrown by functions which allocate.
Example
void AppendTo(std::string& string) {
// rules/A15-4-4/MissingNoExcept.bqrs:
// Function AppendTo could be declared noexcept(true).
static_cast<void>(string.append("foo"));
