Example: class Notifier attr_writer :value end Notifier#value= could be implemented in terms of Notifier#setValue so observers of Notifier receive notification when the value is changed. -- Ticket URL: <http://www.macruby.org/trac/ticket/252> MacRuby <http://macruby.org/>

#430: MacRuby does not reap processes started with popen ---------------------------------+------------------------------------------ Reporter: neeracher@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ in macirb, run the following line: (0..100).each {IO.popen("echo yo") do |f| end} in a separate shell, run "ps -eaf". It will show 100 zombie processes. A source code comparison suggests that MacRuby, as opposed to ruby 1.9, does not call waitpid when popen descriptors are closed. -- Ticket URL: <http://www.macruby.org/trac/ticket/430> MacRuby <http://macruby.org/>

[MacRuby] #629: Bindings not working for subclass

#629: Bindings not working for subclass ---------------------------------+------------------------------------------ Reporter: dylan@… | Owner: lsansonetti@… Type: defect | Status: new Priority: critical | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ Binding to a property that is overridden by a subclass causes a 'valueForUndefinedKey:]: this class is not key value coding-compliant for the key' error. Expected behavior: binding should call the method on the subclass. I've attached a project that throws this error on launch. The AppDelegate contains Person and Teacher instances. The nib file has a label bound to each. Removing the binding to teacher.name or changing the binding to a property that is not overridden makes the bug go away. I was using an early nightly for beta 0.6. I've also tested with the latest nightly: macruby_nightly-2010-03-06-1240.pkg -- Ticket URL: <http://www.macruby.org/trac/ticket/629> MacRuby <http://macruby.org/>

[MacRuby] #507: valueForKey(key) no longer working with NSManagedObject subclasses.

#507: valueForKey(key) no longer working with NSManagedObject subclasses. -----------------------------------+---------------------------------------- Reporter: johnmacshea@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: valueForKey, KVC, Core Data -----------------------------------+---------------------------------------- In MacRuby 0.4 - any method in an NSManagedObject subclass (or in any other class) could be bound (eg via a controller) to a (view) nscontroller/field. Now - in 0.5 beta 1 and 2 (unless a variable of the same name is a property in the Entity that the NSManagedObject represents) valueForUndefinedKey(key) is called in the subclass, if that method exists, or an error occurs (if valueForUndefinedKey(key) does not exist) - eg: [<Student 0x200391280> valueForUndefinedKey:]: the entity Student is not key value coding-compliant for the key "age". This does not occur in a non NSManagedObject subclass - when view objects are bound to other classes' methods(attributes) - it all works fine. The different version of NSManagedObject valueForKey could be the culprit vis a vis valueForKey in NSObject, but in any case - as mentioned - it worked fine in 0.4. Example project attached. -- Ticket URL: <http://www.macruby.org/trac/ticket/507> MacRuby <http://macruby.org/>
