Test suite failure on HDMF 3.14.4

[CodyCBakerPhD]

Found this in the NWB Inspector

We use the following sequence in the actions: https://github.com/NeurodataWithoutBorders/nwbinspector/blob/a7e7172d1e1cabcba703c0c1ada343ab0864f79a/.github/workflows/dandi-dev.yml#L26-L35, usually minus line 34

But without line 34 (forcible pin to previous HDMF version) this results in an error in dandi/tests/test_organize.py:test_ambiguous: https://github.com/NeurodataWithoutBorders/nwbinspector/actions/runs/10712486753/job/29702975698

Unsure what the true source of the problem is though, and if its a problem to be concerned about in general, just wanted to let y'all know

so you are saying that with the new 3.14.4 something what worked before starts to fail? sounds like a possible regression in HDMF ... and indeed our CI is full of red Test fails since awhile, but largely masked by facts that I was aware of some other services running Red and thus ignoring... ok, time to look into it! That test started to fail in 08 on 22nd and on dev-deps which install development versions of hdmf and pynwb (and keyring and nwbinspector) at https://github.com/dandi/dandi-cli/blob/master/.github/workflows/test.yml#L71

so indeed hdmf release of changes from around aug 22 seems to blame ;)

so it is likely of those 3 changes

since not clear what it is -- now will look into actual test fail and see if can point more specifically the effect

it is about

2024-09-05 14:44:24,500 [ WARNING] Completely empty record for /home/yoh/.tmp/pytest-of-yoh/pytest-786/test_ambiguous0/simple2.nwb

and related to creation of that file, not loading etc... And since it complained only about that one, and not the other one -- it is about us "copying" an nwb via NWBHDF5IO in https://github.com/dandi/dandi-cli/blob/HEAD/dandi/pynwb_utils.py#L494 .

    with pynwb.NWBHDF5IO(src, "r") as ior, pynwb.NWBHDF5IO(dest, "w") as iow:
        data = ior.read()
        data.generate_new_id()
        iow.export(ior, nwbfile=data)

as a result of that commit, we are getting a new file...

and it as 12 more of lines in the diff between diffs of h5dump between original and "copied":

is quite a unique "thing" to be used at all present only in the "copy" of the file. ...

and damn -- we are managing to hide away such an error message/exception from the user even at debug level somehow, but there is a problem with HDMF being unable to load such a file

I will for now declare this version of hdmf buggy for dandi-cli and file and issue with HDMF.
