Re: Can you temporarily turn off STDERR?

Ruby

IO#reopen to take

class IO
begin
end
puts “normal stuff 2”
File.open(‘error_log_4’, ‘w’) do |log_file|
$stderr.reopen(‘error_log_5’, ‘w’) do
$stderr.puts “Stuff on error 5”
puts “normal stuff 5”
raise “This message courtesy of raise”
end
rescue => e
puts e
end

end

Awesome. Now, can we break this with threads? Aredridel?

Of course, I wonder if IO#reopen is thread safe anyway, regardless of
the block. I’ve never seriously tested it.

Well, it’s thread-safe, but it’s process-global. It’d get turned off for
the duration of the block, regardless of other threads.
