@Mikejmnez can you take a look please?

[Mikejmnez]

Sure will!

[maxrjones]

Does anyone have plans to address the Zarr-related failures due to store mode changes? We anticipate issues in VirtualiZarr due to this incompatibility. I can take a look if this isn't already being acted on.

[keewis]

doesn't look like it, so if you have the time / motivation feel free to send in a PR

I addressed the half of the failures that related to store modes in https://github.com/zarr-developers/zarr-python/pull/3156. I think @ianhi and @TomNicholas are working on the other dtype related failures in https://github.com/pydata/xarray/pull/10456.

[kmuehlbauer]

There are pydap issues again which I thought to have fixed with #10421. But there are different behaviour for numpy < 2.3.0, numpy = 2.3.0 and numpy >= 2.3.1 and I'm having a hard time to trace the underlying issue.

Also I do not really get to the bottom of this .astype(str) within the tests. Is this just for comparison or what do we expect back from pydap? If its just to check the strings for equality independent of their encoding, it would make sense then to just test for any |S-type and convert unconditionally (version-wise).

On zarr there is also https://github.com/pydata/xarray/pull/10457, but I think there might be some other permission-related changes to make yet - when I run the tests locally with that xarray PR and the latest zarr, I still get a lot of

Is this using a MemoryStore?

[TomNicholas]

Is this using a MemoryStore?

Probably yes, we have a lot of tests which use that.

[maxrjones]

Probably yes, we have a lot of tests which use that.

I'll take a look later today. I thought I had checked that all the tests passed, but must have missed some.

[TomNicholas]

Actually looking again I think the problem is that my new test in that PR uses WrapperStore?

[maxrjones]

ah yes, your store would need to implement with_read_only() which could call the wrapped store's with_read_only().

[TomNicholas]

ah yes, your store would need to implement with_read_only() which could call the wrapped store's with_read_only().

Except that doesn't work because the wrapped store is a MemoryStore. Let's continue this discussion on #10457.

I will spend some time working on this today (I've been working with huge backlog of stuff and I can finally take a look at it).

Also I do not really get to the bottom of this .astype(str) within the tests. Is this just for comparison or what do we expect back from pydap? If its just to check the strings for equality independent of their encoding, it would make sense then to just test for any |S-type and convert unconditionally (version-wise).

I also do not quite understand the .astype(str) purpose (old code inherited there). I think there has to be something on the pydap end of things that can fix these testing issues as opposed to working on the tests itself.
