Deduplication Disassociates ActiveRecord Filename from Underlying Storage

[DBugger32]

Was hoping this was fixed with 3.0.1, but it still occurs. When updating an uploader with the same file, the underlying stored filename is deduplicated, but the active_record filename stays the same. This is the minimal example....

 mount_uploader :signed_electronic_document, OldReleaseUploader, mount_on: :signed_electronic_document_filename

doc =  File.open(File.expand_path('../../fixtures/files/Example Annotated Document.pdf', __FILE__))
r = Release.create!
r.signed_electronic_document = doc
r.save!

puts "After Initial Save -----------"
puts "url     : #{r.signed_electronic_document.url}"
puts "ar name : #{r.signed_electronic_document_filename}"
puts "store_dir files"
puts Dir["/home/app/myapp/private/#{r.signed_electronic_document.store_dir}/*.pdf"]
puts ""
#update with same document
r.assign_attributes(verified: true, signed_electronic_document: doc)
r.save!
puts "After Second Save -----------"
puts "url     : #{r.signed_electronic_document.url}"
puts "ar name : #{r.signed_electronic_document_filename}"
puts "store_dir files"
puts Dir["/home/app/myapp/private/#{r.signed_electronic_document.store_dir}/*.pdf"]

This is the output...

After Initial Save -----------
url     : /uploads/release/signed_document/980191116/Example_Annotated_Document.pdf
ar name : Example_Annotated_Document.pdf
store_dir files
/home/app/myapp/private/uploads/release/signed_document/980191116/Example_Annotated_Document.pdf

After Second Save -----------
url     : /uploads/release/signed_document/980191116/Example_Annotated_Document(2).pdf
ar name : Example_Annotated_Document.pdf
store_dir files
/home/app/myapp/private/uploads/release/signed_document/980191116/Example_Annotated_Document(2).pdf

And sure enough, if you try to load the object and read the file

r.reload
r.signed_electronic_document.read

you receive...

Errno::ENOENT: No such file or directory @ rb_sysopen - /home/app/myapp/private/uploads/release/signed_document/980191116/Example_Annotated_Document.pdf

Expect that the active_record filename and underlying storage should remain synched

PS. A config setting to toggle off/on carrierwave's deduplication efforts would be useful

Sorry I overlooked this. This was already reported as a PR by #2677, and #2679 is my proposal to fix.

Fixed in 3.0.2.
