Rack::Test::UploadedFile / fixture_file_upload outputing file list

[Crystark]

Hi,

Since my recent bundle update, i'm getting strange outputs each time I execute:

fixture_file_upload(creative.resource_file_name, creative.resource_content_type)

Just in case, I've tried replacing it by:

Rack::Test::UploadedFile.new(ActionController::TestCase.fixture_path + medium.creative.resource_file_name, medium.creative.resource_content_type)

But it's the same.

I'm seeing this in my tests (called with rake test) but also when I rake db:reset as i'm using some fixtures for developpment.

I just fixed my version of rails to Rails 4.0.0.rc1 but I started having this problem while i was still using the rails master (edge) version.

Here's the output i'm getting, it's repeated 4 times for each fixture_file_upload call:

Obviously something runs "lsof". I fail to see how this is Rack related?

[Crystark]

I'm sorry. I'm still only begining with rails so as this output was generated by a Rack subclass, i just guessed it was something in rack doing this.
