Re: Proc call is blocking call of finalizer

[Stefan_Salewski]

Well, here is a self contained example:
    
    
    type
      O1 = ref object of RootObj
        i: int
      
      O2 = ref object of O1
        j: int
    
    proc finalizeGObject*[T](o: T) =
      echo "finalizeGObject"
    
    #proc xadd(self: O1; widget: O2) =
    #  discard
    
    proc xadd(self: O1; widget: O1) =
      discard
    
    proc main() =
      var
        o1: O1
        o2: O2
      new(o1, finalizeGObject)
      new(o2, finalizeGObject)
      o1.xadd(o2)
      o2 = nil
      GC_fullCollect()
    
    main()
    

For this I get no output, so finalizer is not called.

But with this
    
    
    proc xadd(self: O1; widget: O2) =
      discard
    
    #proc xadd(self: O1; widget: O1) =
    #  discard
    

we get
    
    
    $ ./t1
    finalizeGObject
