AppVeyor failure

[ocefpaf]

Not sure why AppVeyor is failing with

[Running notebook]: C:\projects\notebooks-demos\notebooks\2016-11-15-glider_data_example.ipynb
[Failed]
An error occurred while executing the following cell:
------------------
import iris
iris.FUTURE.netcdf_promote = True
glider = iris.load(url)
print(glider)
------------------
OSError: NetCDF: Invalid argument

Linux and OS X can execute that notebook just fine 😒

@rsignell-usgs I cannot reproduce that with my old Windows XP VM. If you find some time can you test that notebook on your machine? Maybe that endpoint is blocking AppVeyor...

I'm getting that same error when I try to run that notebook on windows. When I try ncdump in my Anaconda prompt, I get:

(ioos3) C:\Users\rsignell\Documents\GitHub>ncdump -h "http://data.ioos.us/thredd
s/dodsC/deployments/rutgers/ru29-20150623T1046/ru29-20150623T1046.nc3.nc"

That explains why I can access on my old Windows XP VM. Thanks!

I will check what we can do about it but we probably have a bad mix of SSL version in conda-forge.

I try to open in netCDF-Java on windows, I get this:

That doesn't depend on any python!

That doesn't depend on any python!

I know, it is the openssl version used like I mentioned above. Ee can use a more permissive openssl version. I am investigating that... Although I am not sure it is recommended. The error is there for a reason.

Some internet security expert opinion would be nice 😄

I'm assuming this hasn't been sorted out yet but I thought I would just let you know that I just tried this myself on my windows machine. Got the same error. :(

[ocefpaf]

It is not something that we can fix. I am trying a few workarounds though, but they may not be recommended. Stay tuned...

This is fixed via a patch and the next netcdf lib will fix this for good.
