Connections not being released with ActiveRecord 5

[tommyschaefer]

Hi there!

I've run into the same problem as bmizerany#10 using ActiveRecord 5.

I think this is coming from line 33 of lib/sinatra/activerecord:

if ActiveRecord::ConnectionAdapters.const_defined?(:ConnectionManagement)
  app.use ActiveRecord::ConnectionAdapters::ConnectionManagement
end

As far as I can tell, AR 5 doesn't have ActiveRecord::ConnectionAdapters::ConnectionManagement, but I wasn't able to find / see if there's a replacement.

Thank you so much for the time and help!!

If there isn't a replacement, I'm wondering if it would make sense to fall back on the original implementation proposed in that PR? Something like:

if ActiveRecord::ConnectionAdapters.const_defined?(:ConnectionManagement)
  app.use ActiveRecord::ConnectionAdapters::ConnectionManagement
else
  app.after { ActiveRecord::Base.clear_active_connections! }
end
