I've tried to put some diagnostics around this, to repeat the process
till it blows up but tell you about how far it got. This is on the basis
that it would allow us to compare the bugs across platforms better.
Threads in Ruby 1.8 are supposed to be in process. I've closed the
shoes app, had the cmd window associated with it disappear, and then
had a load of shoes windows pop up afterwards. Once a window
containing the number 499 popped up but there is no way I've seen
400 windows come and go.
Anyway, here is the code. Maybe someone else can make it behave.
#!shoes
#
#
require 'thread'
Shoes.app do
def new_app(count)
win = window do
stack do
owner.replace_label "Threads to start"
th = Thread.start do
count.times { para '', :stroke => black }
end
th.join
owner.replace_label "Threads done"
end
end
while not win.started()
owner.replace_label "win not started"
sleep 1
end
sleep 1
return win
end
Thread.abort_on_exception=true
@mutex = Mutex.new
@count = 0
@mutex.synchronize do
@label = para "#...@count}"
end
def replace_label str
@mutex.synchronize do
@label.replace "#{count} " + str
end
end
clipboard = @count
500.times do |i|
@count = i
replace_label ""
win = new_app(@count)
replace_label "got window"
sleep 5
win.close
end
end
