#269: Calling a method on a pointer passed to a KVC validation method fails --------------------------------+------------------------------------------- Reporter: mikael@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: kvc pointer crash --------------------------------+------------------------------------------- If I define a -validate<Key>:error: method in the class used as an NSArrayController's class, any method call on any parameter causes a crash. == Steps to reproduce: == Create a new MacRuby project. Place a table view and a button in the main window. Instantiate a new NSArrayController. Set the class of the array controller to SomeModel, with the key someKey. Bind the table view's single column's value to the array controller's arrangedObject.someKey key path, and check Validates Immediately. Set the button's target to be the array controller, action add:. Create a new Ruby file in the project. Here's the code: {{{ #encoding: utf-8 class SomeModel attr_accessor :someKey def validateSomeKey someKeyPointer, error: errorPointer NSLog "Validating someKey." someKeyPointer.nil? # This is where the program crashes. return true end end }}} Launch the application, add a new row, try to change its someKey. When you press enter, it crashes. Attached is the backtrace I get from GDB. -- Ticket URL: <http://www.macruby.org/trac/ticket/269> MacRuby <http://macruby.org/>

#499: Order declaring class hierarchy gets MacRuby confused about instance variables ------------------------------+--------------------------------------------- Reporter: paul@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: ------------------------------+--------------------------------------------- The following code appears to misbehave in MacRuby. It defines a class hierarchy Alpha > Beta > Gamma, with methods to set and get instance variables. {{{ class Alpha end class Beta < Alpha def setAnotherVar @another_var = "Assigned to another_var in Beta" end end class Alpha def setVar=(var) @var = var end def var @var end end class Gamma < Beta def setAnotherVar @another_var = "Assigned to another_var in Gamma" end end a = Gamma.new a.setVar = "Assigned to var" puts a.var a.setAnotherVar puts a.var }}} Ruby 1.8.7 prints: Assigned to var[[BR]] Assigned to var Whereas MacRuby prints: Assigned to var[[BR]] Assigned to another_var in Gamma Ruby 1.8.7 would appear to be the correct behaviour. MacRuby is getting confused about instance variables. Setting the "another_var" instance variable wrongly changes the "var" instance variable. Declaring the classes strictly in the order of the hierarchy (i.e Alpha then Beta then Gamma) fixes the problem, but in a large project where classes are autoloaded, that may not happen. This is a simplified extraction from a larger project. It was a very elusive bug. Well, is it a bug? -- Ticket URL: <http://www.macruby.org/trac/ticket/499> MacRuby <http://macruby.org/>
