`A12-1-1`: Does not apply transitively

[nbusser-sr]

Affected rules

• A12-1-1: cpp/autosar/explicit-constructor-base-class-initialization

Rule A12-1-1 (required, implementation, automated)
Constructors shall explicitly initialize all virtual base classes, all direct
non-virtual base classes and all non-static data members.

Description

⚠️ I'm not 100% sure if the rule actually allows transitive calls to constructors ⚠️

Let an inherited class having two constructor a and b.
a calls the base class constructor while b calls a.
A12-1-1 gets reported on b because it does not call base class constructor directly (but it calls it transitively through a)

Example

class BaseClass {
    public:
    BaseClass() noexcept = default;
};

class Class final : public BaseClass {
    public:
    Class(void) noexcept : BaseClass() {};
    Class(bool) noexcept : Class() {}; // Triggers `A12-1-1`
};

This is not covered explicitly by the rule one way or another, but seems a reasonable extension to permit.
