Hi, Is there a way to add deep recursion protection to the system? eg. RecursiveObject>>#recurse self recurse So calling `RecursiveObject new recurse` in Dolphin raises an exception right away... Throws the following error with this stack: ProcessorScheduler>>stackOverflow: [] in ProcessorScheduler>>vmi:list:no:with: BlockClosure>>ifCurtailed: ProcessorScheduler>>vmi:list:no:with: RecursiveObject>>recurse RecursiveObject>>recurse In Pharo it goes forever until it hits the memory limit (3.6GiB), at which point doing an Alt+. is useless and you have to kill the VM. The example is pretty simple, but when doing Seaside rendering, it is easy to miss some return, causing the receiver to render recursively, turning your image useless. e.g. MyComponent>>renderContentOn: html html render: self someSubComponent MyComponent>>someSubComponent "Here I forget returning the subcomponent" someSubComponent ifNil: [someSubcomponent := OtherComponent new]. When you render MyComponent... boom, because #MyComponent>>#renderContentOn: will be called recursively. Regards, Esteban A. Maringolo
