No bug: [diffoscope] Output an empty diff if the files do not differ; r=glandium Currently, if the files match and you try to look at the diff, you get { "reason": "file-missing-on-worker", "message": "Artifact \"public/diff.html\" not found at \"/builds/worker/diff.html\"" } which makes it hard to tell if there was an error generating a diff, or if the files matched. This changes things to ask diffoscope to always output a diff, to remedy that confusion. Differential Revision:
