Rails 2.0.1 initializer weird infinite loop situation

Rails
1

Just switched an app over from 1.2 to 2.0.
In accordance with the new convention, I moved my custom configuration
information out of config/environment.rb and into config/initializers/
app_config.rb. I found that my actionmailer config block was causing
an infinite loop (encompassing more than just the block itself).
Nothing like this happened with 1.2.x. Here’s the code (nothing
special):

DOMAIN_NAME = ‘example.com’

Uses lib/smtp_tls.rb (Gmail SSL SMTP requires this)

Rails::Initializer.run do |config|
config.action_mailer.perform_deliveries = false # For now

config.action_mailer.perform_deliveries = true

config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_charset = :‘utf-8’
config.action_mailer.smtp_settings = {
:address => ‘smtp.gmail.com’,
:port => 587,
:domain => DOMAIN_NAME,
:authentication => :plain,
:user_name => ‘mailer@’ + DOMAIN_NAME,
:password => ‘secret’
}
end

…

As is, Rails won’t load and a never ending train of warnings about an
already initialized constant DOMAIN_NAME shows in the console
(evidence that the infinite loop encompasses more than the block). lib/
smtp_tls.rb is not the source of the problem and neither is the
declaration of the constant.

There are two ways to fix this as far as I know - comment out the
block and skip the configuration or put ‘break’ before ‘end’.

Any ideas on what’s behind this?

That’s causing the initializer to be run again from your initializer
file, which loads your initializer file, which runs the initializer
again …

Thanks Fred, that makes perfect sense. That being the case, how would
I inject this configuration information into the mix then?

I think that sort of stuff is fine to stay in environment.rb -
basically it’s not about
extracting stuff from the Rails::Initializer.run do |config| block but
about all the stuff at the bottom.

Will do. Thanks for the advice.
