Hi, recently Arch upgraded `file` to version 5.46. As it happens, I've been building diffoscope and found this issue. ``` @skip_unless_file_version_is_at_least("5.37") def test_difference(differences): expected_diff = get_data("quine_expected_diff") if file_version_is_ge("5.40"): expected_diff = expected_diff[:-1] expected_diff += ", compression method=deflate\n" > assert differences[0].unified_diff == expected_diff E AssertionError: assert '@@ -1 +1 @@\...hod=deflate\n' == '@@ -1 +1 @@\...hod=deflate\n' E E Skipping 100 identical leading characters in diff, use -v to show E - ive data, at least v2.0 to extract, compression method=deflate E + ive data, made by v2.0, extract using at least v2.0, last modified, last modified Sun, Mar 04 2010 00:24:16, uncompressed size 440, method=deflate tests/test_quines.py:63: AssertionError ``` ## Investigation Searching for this issue, I found #251. Indeed, running `file` separately shows the response: ``` $ file --version file-5.46 magic file from /usr/share/file/misc/magic seccomp support included $ file tests/data/quine.zip tests/data/quine.zip: Zip archive data, made by v2.0, extract using at least v2.0, last modified, last modified Sun, Mar 04 2010 00:24:16, uncompressed size 440, method=deflate ``` Running the build with `file 5.45` completes fine. ## Analysis The changed output of `file` is at fault. The fix probably requires another conditional [here](https://salsa.debian.org/reproducible-builds/diffoscope/-/blob/master/tests/test_quines.py?ref_type=heads#L57-63) to support the new message. ## Appendix [diffoscope-283-1-x86_64-check.log](/uploads/4357592df3f295d91131fa668f50eebd/diffoscope-283-1-x86_64-check.log)
