Summary: Ref T12464. This is a very old method which can return an existing file instead of creating a new one, if there's some existing file with the same content. In the best case this is a bad idea. This being somewhat reasonable predates policies, temporary files, etc. Modern methods like `newFromFileData()` do this right: they share underlying data in storage, but not the actual `File` records. Specifically, this is the case where we get into trouble: - I upload a private file with content "X". - You somehow generate a file with the same content by, say, viewing a raw diff in Differential. - If the diff had the same content, you get my file, but you don't have permission to see it or whatever so everything breaks and is terrible. Just get rid of this. Test Plan: - Generated an SSH key. - Viewed a raw diff in Differential. - (Did not test Phragment.)
