#408: leaked Tempfile don't get cleaned up [...] Changes (by lsansonetti@?):

I implemented ObjectSpace finalizers as part of r2918 and now your snippet behaves like the old Ruby.

This does indeed fix the main problem—the program running out of file descriptors. Thanks!

The behavior still differs significantly from Ruby 1.8 behavior (though it may match 1.9 this regard): When running the program I included in the bug to completion, the ruby 1.8 version will clean up all temp files, while the MacRuby version will leave behind dozens of temp files (everything created after the last gc run). Presumably, one could force this cleanup by running gc at the end of the program, but I'm not sure this would be a popular thing to do in the runtime, and if it matters to a client, this can be done in client code.

I think this is a different bug, it looks like we don't force the call of all finalizers before dying. $ ./miniruby -e "o=Object.new; ObjectSpace.define_finalizer(o, proc{p 42}); p :dying" :dying $ ruby19 -e "o=Object.new; ObjectSpace.define_finalizer(o, proc{p 42}); p :dying" :dying 42 I remember we trigger a full - synchronous collection before exiting but apparently it doesn't help. Could you file a new ticket on Trac for this? Thanks, Laurent
