The Actions CI workflows have recently been producing jobs that all fail early (or are cancelled early due to parallel such failures) on the same setup errors, as copied in summary below. This PR aims to test, and then merge, a fix for this, so we can move onto seeing a true pass or fail output.

Despite what the note on the penultimate quoted line says, I am fairly certain this is actually a pip-related issue stemming from older versions of pip being used because (I was unaware of this before, but after investigation here I now realise) we are pretty behind in terms of versions specified for the so-called 'reusable' workflows which we specify in order to do common Actions jobs tasks such as checking out a repository and setting up Python, etc. By updating to the latest versions of those, notably the latter, I think we will get a pip version which won't hit this error. Testing that theory now here via the set of job 'checks' that get run on this PR...

(Whether the version updates fix this issue at hand or not, it is worthwhile to do the update. I'll go in and update all of the other workflow files in a similar way shortly in a separate PR.)

By updating to the latest versions of those, notably the latter, I think we will get a pip version which won't hit this error. Testing that theory now here via the set of job 'checks' that get run on this PR...

OK the results are in and my theory was wrong 😔 . The version updates need doing anyway so will stay, but something else is needed to fix the underlying issue. I'll have a look tomorrow, probably first I'll try adding a command to upgrade pip at the appropriate place and see if that helps...

Thanks for investigating this, Sadie - it'll be great to get these working again.

Opening and closing to re-trigger the jobs...

And again, last time there was nothing that would cause any difference, just some informational print-outs, this time I am upgrading pip which might help (if it can be upgraded at all)...

Argh, I should have just listened to the note "This error originates from a subprocess, and is likely not a problem with pip." in the first place! The issue was that an old module, now moved elsewhere, was specified in the setup.py and causing the failure (I thought error: package directory 'cf/data/abstract' does not exist was a symptom and not referring to the root cause of the issue, given that editable installation has always been working fine for me locally, and I could see no reference to data.abstract in any __init__.py, but forgot to check the setup.py and it was indeed the problem 🤕 ).

Anyway, re-triggering to show that the setup stages don't trip on the same error now, and to see how far the jobs get now...

OK, progress. Now we are onto the issue:

Run cd /home/runner/work/cf-python/cf-python/main/cf/test
Traceback (most recent call last):
  File "/home/runner/work/cf-python/cf-python/main/cf/__init__.py", line 124, in <module>
    import cfunits
ModuleNotFoundError: No module named 'cfunits'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "test_Data.py", line 28, in <module>
    import cf
  File "/home/runner/work/cf-python/cf-python/main/cf/__init__.py", line 126, in <module>
    raise ImportError(_error0 + str(error1))
ImportError: cf v3.14.0b0 requires the modules numpy, netCDF4, cftime, cfunits, cfdm, psutil, dask, packaging. No module named 'cfunits'
Error: Process completed with exit code 1.

I will look into this, a further setup issue, shortly (a bit later). I won't merge this until we get the test suite running across all jobs.

Great: we are now at the stage where the jobs complete the setup successfully and run the test suite, though that appears to be failing with some test method failures I haven't seen locally.

@davidhassell I have noticed a funky HDF5-related output as follows, though weirdly it goes on to say the test passes ok despite the issues it complains about. Do we need to worry about this, do you think?

Could we replace this line with

        "cf.data.array.abstract",

just for backwards compatibility?

Yes, sure, at least I think so and will add it in to check it doesn't break the install.

I was going to ask, once I'd updated the other CI workflows, whether we need to extend the packages listing for any other data packages new or moved during the Dask migration, and whether we want to do that now or pre-release of 3.14. I guess we do since I see:

$ find . -type f -name '__init__.py'
./fragment/__init__.py
./fragment/abstract/__init__.py
./array/__init__.py
./array/abstract/__init__.py
./array/mixin/__init__.py
./__init__.py
./mixin/__init__.py

but I am not sure which of the corresponding packages we want, or indeed need, to list. Probably all of them need to be included?

@davidhassell what do you want me to do here, namely to edit as packages in the setup.py, or should we do it later / elsewhere (see my comment above)?

You're probably offline now, so I'll take your immediate suggestion and add "cf.data.array.abstract" for now so I can merge, but we will need to ensure we've covered everything in the packages sometime before we release...

Hi Sadie, the HDF errors seems to be related to the lossy compression filters introduced in netCDF-C 4.8.0 ('_QuantizeBitGroomNumberOfSignificantDigits'), and thereforre might be related to a neCDF-C/HDF5 version mismatch. I'm not sure which netCDF-C version is being used.

Some evidence of a workaround: https://stackoverflow.com/questions/72821108/hdf5-warnings-when-accessing-xarray-dataset
This may have been fixed in netCDF-C v4.9.1: Unidata/netcdf-c#2458

Thanks for pinpointing the HDF errors David and good spot on finding an issue in netcdf-c reporting a very similar STDERR. I lifted the output from the job log of the last running job which failed first, namely https://github.com/NCAS-CMS/cf-python/actions/runs/3690972465/jobs/6248536987, which states:

...
Run date: 2022-12-14 01:50:15.069650
Platform: Linux-5.15.0-1024-azure-x86_64-with-glibc2.35 
HDF5 library: 1.12.2 
netcdf library: 4.9.0
...

which matches the:

netCDF 4.9.X.

quoted in the netCDF-C Issue.

This may have been fixed in netCDF-C v4.9.1: Unidata/netcdf-c#2458

Great, I'll work out if we can upgrade to 4.9.1 somehow, though it is good to know generally it is unrelated to any of the cf-python code itself. I'll pop that in a separate issue though, since this PR concerns fixing the setup of the CI jobs and I don't want to muddy the waters.

I squashed a few commits so had to do a force-push just now, hence the many commits being reported at once.

I've updated all of the workflows to reference the latest 'reusable workflows' in 23bfcf9. Those workflows don't get run as jobs on this branch, though I am thinking that we can shortly start using the old standard full test-suite run since we are aspiring, and not far off, getting the full test suite to pass, as outlined in #428. Then I can just delete the dask-migration-testing.yml temporary workflow as it is no longer needed. But I'll wait until we get that (essentially test_Data) to pass, because we are seeing some issues due to undetected files (see #495).

I'll just add a final commit to convert the other workflows to do a no-dependency install of cf, which is more robust, then re-confirm the job results, then I can merge this as the underlying issue has been fixed.

Setup still completes successfully but we're now hitting an issue relating to #524, which I will investigate separately. But the issue behind the PR has been solved, namely to fix the setup issues, and I have updated the various Actions workflows in the process, by:

  • updating the setup.py for new modules;
  • using the latest versions for all referenced and utilised reusable workflows;
  • moving to use a no-dependency install of cf which is more robust.

Doing one final re-trigger check and we are ready to merge...
