Proposing as an SRU (help me if I'm doing it wrong): ===== When ===== Has an obviously safe patch.
===== Impact ===== I don't know which program available directly within Ubuntu is written in Ruby-GTK+, but those which do and which are using the Ruby Thread class are broken, and of course developing such a program is broken too. The fix is available in ruby-gnome2 since version 0.19.2 and was introduced through SVN revisions 3692[1] and 3694[2]. Both are within the attachment "ruby-gnome2-gtk-thread-patch.debdiff" in comment #1. [1] http://ruby-gnome2.svn.sourceforge.net/viewvc/ruby-gnome2?view=rev&revision=3692 [2] http://ruby-gnome2.svn.sourceforge.net/viewvc/ruby-gnome2?view=rev&revision=3694 ===== Reproduce the bug ===== Here is another example for reproducing this bug: require "gtk2" include Gtk, GLib # Create widgets window = Window.new vbox = VBox.new(false, 2) button = Button.new("Run Thread") progress = ProgressBar.new # Pack widgets window.add(vbox) vbox.add(button) vbox.add(progress) # Set default window size window.default_width = 120 window.default_height = 50 window.show_all # Connect signals button.signal_connect("clicked") do Thread.new do puts "Thread started!" progress.pulse end end window.signal_connect("destroy") { main_quit } # Show all and run main # start the GTK+ main loop The test program shows a window with a button and a progress bar. Clicking the button will execute a Ruby Thread object, and the GUI visual elements/the GTK+ main loop will remain freezed. The example in the bug description is supposed to print dots, and instead it doesn't. -- Multithreaded Gtk applications using Ruby bindings freeze https://bugs.launchpad.net/bugs/514899 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
