#796: Dispatch::Queue.main created with a different Queue class?!? ----------------------------------------+----------------------------------- Reporter: ernest.prabhakar@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: ----------------------------------------+----------------------------------- The "Dispatch::Queue.main" fails the equality check in gcd.c, even though it appears identical. $ macruby -r dispatch -e 'Dispatch::Job.new {sleep 1}.join(Dispatch::Queue.main) {puts "!"}' /Library/Frameworks/MacRuby.framework/Versions/0.7/usr/lib/ruby/1.9.2/dispatch/job.rb:28:in `join:': expected class of [0x2000c1160] to be Dispatch::Queue [0x20004c8a0], but got Dispatch::Queue [0x2000c1120] (ArgumentError) from /Users/Shared/MacRuby-trunk/-e:1:in `<main>' That is, the reported name is the same, but the pointer differs. Ruby itself seems to think the classes are the same: $ macruby -r dispatch -e "p Dispatch::Queue.main.class == Dispatch::Queue.concurrent.class" true Concurrent queues work fine: $ macruby -r dispatch -e 'Dispatch::Job.new {sleep 1}.join(Dispatch::Queue.concurrent) {puts "!"}' as do private queues: $ macruby -r dispatch -e 'Dispatch::Job.new {sleep 1}.join(Dispatch::Queue.new("1")) {puts "!"}' I don't know if the problems is the class-equality check, or how the main queue gets a class assigned. -- Ticket URL: <http://www.macruby.org/trac/ticket/796> MacRuby <http://macruby.org/>
