|
|
// 1) UIManagerBinding strongly retains UIManager. The JS VM
|
|
// strongly retains UIManagerBinding (through the JSI).
|
|
// These functions are JSI functions and are only called via
|
|
// the JS VM; if the JS VM is torn down, those functions can't
|
|
// execute and these lambdas won't execute.
|
|
// 2) The UIManager is only deallocated when all references to it
|
|
// are deallocated, including the UIManagerBinding. That only
|
|
// happens when the JS VM is deallocated. So, the raw pointer
|
|
// is safe.
|
|
//
|
|
// Even if it's safe, why not just use shared_ptr anyway as
|
|
// extra insurance?
|
|
// 1) Using shared_ptr or weak_ptr when they're not needed is
|
|
// a pessimisation. It's more instructions executed without
|
|
// any additional value in this case.
|
|
// 2) How and when exactly these lambdas is deallocated is
|
|
// complex. Adding shared_ptr to them which causes the UIManager
|
|
// to potentially live longer is unnecessary, complicated cognitive
|
|
// overhead.
|
|
// 3) There is a strong suspicion that retaining UIManager from
|
|
// these C++ lambdas, which are retained by an object that is held onto
|
|
// by the JSI, caused some crashes upon deallocation of the
|
|
// Scheduler and JS VM. This could happen if, for instance, C++
|
|
// semantics cause these lambda to not be deallocated until
|
|
// a CPU tick (or more) after the JS VM is deallocated.
