Unfortunately, the HDF5 filter system provides no way to discover the actual types of the parameters to a filter. It only sees a sequence of unsigned integers. The actual types...

Unfortunately, many of our early tests in nc_test, nc_test4, and ncdump especially use files supposedly created in tests presumed to have run previously. Doing parallel make tests has completely screwed...

I think we can kill the interference cases. The real problem is that some tests depend on the output of other tests as their input.

Ugh. This is being set at posixio.c:740. But I have no insight into the posixio code; it is hopelessly complicated (Thanks Glenn :-))

As a workaround, try changing ```` "s3://mybucket/zarr_key/#mode=zarr,s3" to "https://s3.amazon.com/mybucket/zarr_key/#mode=zarr,s3" ````

We would like to support local servers, but have no way to test it. Try this experiment. Execute this command and post the output. > ncdump -h '[log][show=fetch]https://localhost:9444/data/SWOT_L2_LR_PreCalSSH_Expert_002_086_20230814T031152_20230814T040129_PIA1_01.nczarr#mode=nczarr,s3'

Also, the issue may be that the aws-sdk-cpp library does not support non-amazon servers. Starting with netcdf-c-4.9.3, we have an alternate library that may work (or can be made to...

Part of the problem is that the URL you using is being treated as if it is a DAP2 URL. Try changing the "#mode=s3" at the end to "mode=zarr,s3" and...

When I put "https://s3.datalake.cnes.fr/" into my browser, it says the site does not exist.

See the following functions: 1. libdispatch/ds3util.c#NC_s3sdkinitialize() 2. libdispatch/ds3util.c#NC_aws_load_credentialss() 3. libdispatch/ds3util.c#NC_getactives3profile() 4. libdispatch/ds3util.c#NC_authgets3profile() If memory serves, (1) is called at initialization to load various environment variables, some of which affect the...
