test_datalad_credential_helper - AttributeError: 'NoneType' object has no attribute 'credential' #7347

@adswa summarized observing it on #7340 (comment)

I have ran into it on a fresh (woohoo -- a new laptop) box in a sample run of pytest -n10 -v datalad (done in 2 minutes)

WTF on that box (shows that I do not even have git user configured)

It is highly recommended to configure Git before using DataLad. Set both 'user.name' and 'user.email' configuration variables.

so it is some interaction with other tests. Unfortunately I have not got the ultimate minimal but here is one which does trigger it:

bpoldrack · 2023-03-27T07:45:39Z

Thx, @yarikoptic - reproduced. Looking into it. I suspect the lazy loading of providers gets in the way here. In any case, the delivered providers are not up-to-date.

bpoldrack · 2023-03-27T10:50:40Z

Ok, so that is the problem indeed. Providers.from_config_files call get_dataset_root(""), which will always deliver the same "dataset root" (whatever that's supposed to mean in this context). And if it didn't change and the function isn't caled with reload, then it just delivers whatever providers it found before. Hence, the new provider config in the test isn't loaded.
While I don't understand what get_dataset_root("") is supposed to do under what circumstances, the only recent change I can see, is the type annotation to get_dataset_root. So, I am at the usual stage of "How did this ever work?"/"Why is it starting to fail only now?".

I suspect, that get_dataset_root("") was assumed to deliver the dataset root based on CWD, as in Path("") == Path("."). But something about that doesn't actually work.

bpoldrack · 2023-03-27T11:40:51Z

I think, I got the problem. Not sure, why it only shows now, but since there's no recent change in the code involved, I suppose it's a change in tests.
The caching of Providers.from_config_files() doesn't actually work. That means, it will deliver the previous result, whenever PWD is in a dataset's root and was in a (sic!) dataset's root before. So, triggering is a matter of order in the tests. The test would pass if it's the first time in the python process, that provider configs are read while in a dataset root dir. The keyword here is: "a". The cache would not realize that PWD is in a different dataset's root now than it was before.

Providers.from_config_files() stores the result of `get_dataset_root("")` and delivers the previous resut, if not called with `reload` and the dataset root is the same. However, what effectively is stored when CWD is a dataset's root is the empty string - so, effectively `.`. But this would be the same for any dataset root we are in, therefore this lazy loading would not recognize, that the dataset changed. This lead to side-effects of the order of test execution, when a test provided new config files. Those files would be ignored, when providers were read from within a different dataset before. Hence, use the absolute path to store and compare. Closes datalad#7347
