BagLinterTest fails under MacOs

[ThomasJejkal]

Given

• bagit-java 5.0.4
• MacOs High Sierra 10.13.2

When

• I build with tests under MacOs

Then

• BagLinterTest fails in line 43: assertEquals("Warnings missing: " + diff.toString() + "\n", expectedWarnings, warnings);

Obviously, removing BagitWarning.DIFFERENT_NORMALIZATION from the list of expected warnings is not longer necessary.

I also run MacOs High Sierra 10.13.2 and it does not fail for me. How is your hard drive formatted? Mine is APFS (Encrypted)

[ThomasJejkal]

Indeed, this is strange. I'm using APFS (Unencrypted), too. Currently, I'm encrypting my filesystem to see if this has any influence, but I don't think so. Maybe the German system language causes this issue?

I've played around a bit with ManifestChecker#checkNormalization and I found out, that during BagLintTest#testLintBag 'src/test/resources/linterTestBag/data/Núñez' is normalized to 'src/test/resources/linterTestBag/data/Nu´n~ez' unless I'm using Normalizer.Form.NFC

Edit:
Are you sure that your hard drive is APFS formatted and not HFS+, maybe your source code directory is on a separate disk? In this issue vgough/encfs#316 there is a comment on how to check for NFD or NFC from 5 May 2017 and in my case, the NFD normalized form applies.

Edit2:

Ok, it seems that the different behaviour is indeed caused by the German locale settings. Obviously, NFD as well as NFC normalization have to be supported somehow.

[johnscancella]

Do you still get this error if you change the Locale to english in the test?

[ThomasJejkal]

Changing the locale in the code doesn't change anything. Also changing the system language to English has no influence. According to this article it seems that this issue is related to APFS and indeed, the colleague running her iMac with an English Locale is still not using High Sierra and therefore also no APFS but HFS+. However, the fact that the tests are succeeding on your machine running APFS is now even more confusing.

What is the output from the diskutil? Mine is

For me this looks quite similar:

Yeah doing a diff, the only difference is the size and UUIDs. I am running on a old macbook air, so I have upgraded several times. Did you always have APFS, or like me did you upgrade?

[ThomasJejkal]

I'm not totally sure, but I think that I've upgraded it with macOS High Sierra.
