ActiveSupport 3.0.6: require 'active_support/core_ext' generates "circular require" warning

Rails
#1

Hello,

i noticed some strange warnings when doing

require ‘active_support/core_ext’

with activesupport 3.0.6.
If i do

gem ‘activesupport’, ‘=3.0.5’
require ‘active_support/core_ext’

then it works fine.
Is this a bug in rails 3.0.6?

More precisely, if i do

$ irb -w

require ‘active_support/core_ext’

i get a warning “warning: loading in progress, circular require
considered harmful” with a long page of explanations.
If i do

$ irb -w

gem ‘activesupport’, ‘=3.0.5’
require ‘active_support/core_ext’

then it is fine.

What is this warning about?

Thanks.

Alexey.

Alexey, I would recommend filing a ticket/issue against the gem on
github.com. However, if it’s
just a warning, I wouldn’t worry too much about it.

Good luck,

This warning is still generated in activesupport 3.0.7.

I submitted a bug report here:

Is this the right place?

Perfect.

A patch solving the issue increases the likelihood of being fixed by
some orders of magnitude :). I encourage you to try it, there’s a
guide that may help:
