570416 - Create a static analysis script for detecting classes which should participate in cycle collection

Status: RESOLVED DUPLICATE of bug 423032

(Developer Infrastructure :: Source Code Analysis, defect)

Description

[(no longer active)]

Let's say we have class A which participates in cycle collection.

Scenario A:

Given:

class B {
  A * ptr;
  // ....
};

class C {
  nsCOMPtr<A> ptr;
  // ...
};

class D {
  nsRefPtr<A> ptr;
  // ...
};

class E {
  nsCOMArray<A> arr;
  // ...
};

Classes B, C, D, and E also need to take part in cycle collection.

Scenario B:

Given:

class F : public A {
  // a strong pointer to any object
};

Class F also needs to take part in cycle collection.

These cases should be possible to detect using a static analysis script.

Hmm, looks like it, yes.
