Conditional versions checking everytime uploader called?

[adysson]

Hi,
after update of Carrierwave from 0.6.2 to 1.0.0, our app started to be painfully slow.
We use conditional versions in an uploader i.e. Object#logo. By method is_big_enough?, it checks source image resolution (using mini_magick gem) before versions :medium and :large are created - to prevent increasing of image resolution i.e. from 200x200px to 400x400px.
There are other versions without conditionals: :small and :semi_small
In Carrierwave v. 0.6.2, if I call object.logo.small.url, conditional method is_big_enough? is not called.
In Carrierwave v. 1.0.0, conditional method is_big_enough? seems to be called everytime.

In a big page with 100+ calls to various instances of the uploader, loading of page starts to be painfully slow, because is_big_enough? uses mini_magick which touches HDD/SDD.

Is this desired behavior because of some reason or it happens by mistake?
Thank you

Bumping, this needs input from the authors.

The change itself came from #1351, but makes some sense.
So what I recommend is to get dimensions of the file and store it in some model columns on processing, so the dimensions can be checked with little overhead later.
