Linus Groh	f27bc56e5e	LibJS: Capture promise capability in new_promise_capability() executor ... This is how the spec suggests implementing this; we need to be slightly more verbose as our PromiseCapability implementation cannot hold arbitrary JS values. Unfortunately it makes the error message slightly more ambiguous as we no longer expose the non-function value to the outer scope (we could!), but at least we don't UAF the stack allocated values anymore :^)	2022-10-02 23:02:27 +01:00
Linus Groh	fc9d587e39	LibJS: Make PromiseCapability GC-allocated ... A struct with three raw pointers to other GC'd types is a pretty big liability, let's just turn this into a Cell itself. This comes with the additional benefit of being able to capture it in a lambda effortlessly, without having to create handles for individual members.	2022-10-02 23:02:27 +01:00
Linus Groh	c2326ec95a	LibJS: Move PromiseCapability into its own cpp/h file ... This is not strictly connected to PromiseReaction in any way. Preparation before doing some actual work on it :^)	2022-10-02 23:02:27 +01:00
