[MacRuby] #795: GCD inconsistently copies local variables inside blocks

#795: GCD inconsistently copies local variables inside blocks ----------------------------------------+----------------------------------- Reporter: ernest.prabhakar@… | Owner: lsansonetti@… Type: defect | Status: new Priority: critical | Milestone: Component: MacRuby | Keywords: ----------------------------------------+----------------------------------- The expectation is that Ruby blocks will have their local variables copied before being passed to GCD, to avoid errors from accessing them after they are destroyed. However, that does not seem to always happen. For example: $ macruby -e 'i=0; Dispatch::Queue.new("i").sync {i = 42}; puts i' returns '0' as expected. However, this does not: $ macirb irb(main):001:0> i=0; Dispatch::Queue.new("i").sync {i = 42}; puts i 42 => nil It appears to be copied properly in the block_spec.rb test: it "should create const copies of dynamic (local) variables" do i = 42 @q.sync {i = 1} i.should == 42 end But not in the README.rdoc for the dispatch module (aka dispatch_methods.rb sample): n = 0 job = Dispatch::Job.new { n = 21 } job.join puts "n (after): #{n} => 0?!?" # [returns 21, not 0] Any suggestions? -- Ticket URL: <http://www.macruby.org/trac/ticket/795> MacRuby <http://macruby.org/>

NSKVONotifying_ proxy class
by Dave Baldwin 29 Jul '10

29 Jul '10

I am trying to find the class name of a KVO compliant class I have created (called test below). I am assuming that MacRuby inserts a proxy class in front of my class to implement the KVO protocol. How do I get the name of my original class? puts test.class gives some class reference address like #<Class:0x200570360> - not particularly useful. puts NSStringFromClass(test.class) gives NSKVONotifying_test I could just strip NSKVONotifying_ from this string but this assumes this prefix will never change. Is there a better method I can use to gain access to the original object or its class? Thanks, Dave.
