Hi Park,
I tried your latest patch and ran the sample code:
readPipe, writePipe = IO.pipe
t = Thread.new{
sleep 5
while true
sleep 0.1
puts "got #{readPipe.readline.length} bytes"
end
}
i = 1
while true
i += 1
sleep 1
puts "hello from main"
if i > 3
writePipe.puts "a"*2048
end
end
t.join
At the console I typed the word "world", let it run for a bit, then
hit
Ctrl-C. It mostly seems to work. Here was the difference between Ruby
with your patch and JRuby 1.1.1.
# Ruby 1.8.6-114 with patch
C:\Documents and Settings\djberge\workspace>ruby pipe_test.rb
hello from main
hello from main
hello from main
got 2049 bytes
hello from main
got 2049 bytes
hello from main

hello from main

pipe_test.rb:14:in `sleep'': Interrupt
from pipe_test.rb:14
C:\Documents and Settings\djberge\workspace>world
''world'' is not recognized as an internal or external command,
operable program or batch file.
# Jruby 1.1.1
C:\Documents and Settings\djberge\workspace>c:\jruby\bin\jruby pipe_test.rb
hello from main
hello from main
hello from main
hello from main
hello from main
got 2049 bytes
got 2049 bytes
got 2049 bytes
hello from main
got 2049 bytes
hello from main
got 2049 bytes
Terminate batch job (Y/N)? y
Is the difference anything we should worry about?

Dan

I''m just not sure what the proper behavior should be and I''m trying to work it out. I''ll see what I can come up with as far as a patch (assuming one is needed). I think our options are easier if we limit ourselves to Win2k or later (or even XP or later). This is still a HUGE improvement over the current MRI behavior. :) Regards, Dan

In my test with the cygwin ruby version, cygwin fails to emulate select system call in colsole input. it act just like my patch version. Emulating Linux select is my goal. But it is not easy for now.

But it is not easy for now.Maybe this is just a platform specific issue that we shouldn''t worry about. The behavior on my OS X box was a little different than JRuby even. I did read over this article: http://www.darkcoding.net/software/non-blocking-console-io-is-not-possib le/ Perhaps we could use SetConsoleMode? I haven''t played with it yet.
