Updating BIDS validator and schema to contemporary upstream equivalent #1050

TheChymera · 2022-07-08T04:17:28Z

Brought our code back in sync with upstream BIDS, as we finally have upstream ome.zarr support and there is no longer any reason to maintain a fork of the specification.
This also fixes: #1037

Ideally this will be the last update of bundled code as we are working on importing the built-in Python validator as a library.
Should the need for specification forking arise in the future, this should best be handled via the parameterized schema directory.

~~Draft for now as there might be inconsistencies I haven't spotted.~~

Additionally, we might want to start using the reference bids-examples repository for validation (rather than our own fork).
To be able to perform all relevant tests, this would require having at least one broken dataset in the examples, so that we can verify errors as well: bids-standard/bids-examples#327

In any case, using vanilla upstream would add another ~10s to the BIDS validator tests; as our fork had stripped a lot of the datasets. While we will prospectively no longer run the validator tests themselves (these would be run by the bids-schemacode package), we still need BIDS example data to construct our derivative BIDS datasets for higher-level function testing...

Any ideas if we can somehow check out only some of the files to reduce download time? @yarikoptic

only started, need to switch, please attend to --report option meanwhile

-    "Only usable if `--report` is not already used.",
+    help="Whether to write a report under a unique path in the current directory. ",
 )


so we are breaking CLI ... why not just to keep --report to be an option to provide the path and if not specified, assume that no report writing was requested - print to the screen?
Note: I might not be even able to write to current directory (dataset might be owned by someone else).

functionality wasn't broken, help text was just incorrect.

You removed --report-flag and made --report from taking a string (path) into being is_flag -- so, it got broken that user no longer would be able to say --report myvalidation.log. And I think it is worth removing somewhat odd --report-flag so ok to break but we better "make it right" this time and avoid future breakage.
If you really want to be fancy and support also bool like behavior, I guess you would need to make it nargs='?' (if click supports it, @jwodder could help) and then if not report - assign that default path to the log, so user could do both --report and --report mylog.log.
Alternative -- not bother with "bool" like behavior in CLI, and just make it demand path string.

NB: please do not mark such comments Resolved - let original Author decide if they were resolved or not since it makes it harder for a reviewer to locate prior comments while re-reviewing and see if prior concerns were addressed.

--report handling still needs to be fixed and tested better

@yarikoptic

so, it got broken that user no longer would be able to say --report myvalidation.log

It didn't get broken, the feature was simply removed. I added it initially because I thought it would be helpful, and I decided that in fact it is not. The validation() function which I understand we want to merge BIDS into at some point does not have such a parameter, and since DANDI doesn't manage logging this way I see no reason to do it for this function specifically...

I suggest still using a variable for the log base directory, but set it to $TMPDIR (falling back to /tmp) by default.

This is for upstream usage, we wrap this command and pass the DANDI log directory via appdirs. /tmp/ is tricky as it's ephemeral on some systems, and users might not know how their system handles it. /var/tmp is the safer bet.

Compare:
https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch05s15.html
to
https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s18.html
Particularly:

Programs must not assume that any files or directories in /tmp are preserved between invocations of the program.

is pretty much a non-starter for logging which might need to be consulted over a longer period.

 def validate_bids(
    bids_paths,
-    schema_reference_root="{module_path}/support/bids/schemadata/",
+    schema_reference_root="/usr/share/bids-schema/",


Under what conditions is this default used, and why would we expect anything to be in this directory?

In the DANDI use case this is never used, but this is bundled code from upstream, which we will soon no longer track but import from a python dependency. Prospectively, the dependency would find the BIDS schema index in that directory, as that is where architecture-independent read-only user data belongs as per the FHS.
