Memory leak about kaminari HOT 7 CLOSED

Hi,

Thank you for your report.
I think I should fix that but I could not reproduce the leak.
I tested on MacOS 10.6, Ruby 1.8.7 & 1.9.2, Rails 3.0.4 and edge, Mongrel 1.2.0.pre2, Kaminari 0.9.9.

Can you please show me more info?
Does it happen on vanilla Rails app + Kaminari?

Investigating further I found that what's happening is that all ActiveRecord::Base objects are kept in memory following each request. I have the same problem with this gem: https://github.com/soveran/ohm (though it doesn't happen unless I do something with an Ohm::Model, and then the AR objects start leaking).
I'm on the same setup as you so I guess this has something to do with my app, weird.

I confirm this issue as well using Rails 3.0.1 + Thin 1.2.7 + Kaminari 0.10.1. Removing Kaminari from my Gemfile eliminates the rapid memory consumption.

Thank you guys for reporting this issue.
Yes, this was really a weird problem, but finally fixed by just one single line of code! amatsuda@cb65a17

The root cause of this problem was that Kaminari had eliminated AR::Base.descendants, and thus Rails failed to reload the models.
I just released a gem including this commit, so could you please try out the version 0.10.4 gem?

Thanks!

Yep, v0.10.4 fixed this issue for me. Thanks!

Fixed for me as well! Thanks for creating this gem.
