no logging in production mode?

verified.

I do seem to get logging for going to a page that doesn't exist. Try going to /pathThatDoesNotExist. I get

Rendered /Users/me/projects/ruby/rails3/actionpack/lib/action_dispatch/middleware/templates/rescues/routing_error.erb within /Users/me/projects/ruby/rails3/actionpack/lib/action_dispatch/middleware/templates/rescues/layout.erb (2.2ms)

I had the same issue. Turned out to be that Rails.logger.auto_flushing was set to 1000 by default in production mode, making it appear that it was nonfunctional:

$ script/console production
New RightAws::Ec2 using single-threaded mode
Loading production environment (Rails 3.0.pre)
irb(main):001:0> Rails.logger
=> #<ActiveSupport::BufferedLogger:0xb7807c00 @auto_flushing=1000, @buffer={}, @level=0, @log=#<File:.../log/production.log>, @guard=#<Mutex:0xb77ff294>>

This comes from railties/lib/rails/bootstrap.rb:70

logger.auto_flushing = false if Rails.env.production?

and activesupport/lib/active_support/buffered_logger.rb:94

def auto_flushing=(period)
  @auto_flushing =
  case period
  ...
  when false, nil, 0; MAX_BUFFER_SIZE

so then :

irb(main):004:0> Rails.logger.inspect
=> "#<ActiveSupport::BufferedLogger:0xb7807c00 @auto_flushing=1, @buffer={}, @level=0, @log=#<File:/home/deploy/wrangler/releases/20100124150359/log/production.log>, @guard=#<Mutex:0xb77ff294>>"
irb(main):006:0> Rails.logger.auto_flushing=false
=> false
irb(main):007:0> Rails.logger.inspect
=> "#<ActiveSupport::BufferedLogger:0xb7807c00 @auto_flushing=1000, @buffer={}, @level=0, @log=#<File:/home/deploy/wrangler/releases/20100124150359/log/production.log>, @guard=#<Mutex:0xb77ff294>>"

Is this the intent, to disable auto_flushing and force developers to manually flush the rails log in production mode? I would have expected auto_flushing=1.
