Hi,
I'm trying to control an external process I'm running and quit it in
case it got
stuck.
To do that I have to check that the external exe keeps writing on
stdout, if it doesn't update it for a while I'll quit it.
I came up with the following code (using threads) but the sleep in the
main thread blocks everything. (The same code works under Mac OSX)
Is there something I'm doing wrong?
Or a better way to achieve what I need?
Thanks a lot in advance
n = 0
t1 = Thread.new
{
begin
IO.popen("executable.exe") do |pipe|
pipe.each("\r") do |line|
puts line
n += 1
end
end
end
}
k = 0
while t1.alive?
sleep(10) # DOESN'T SEEM TO WORK ON WINDOWS
if k == n
puts "DEAD"
t1.raise("close")
end
k = n
end

pipe=IO.popen("executable.exe")
io=select([io],nil,nil,10) #10 - timeout
if io==nil
puts "DEAD"
t1.raise("close")
end
.
