h5file.visititems(...) raises exception

[fmfreeze]

Thank you Exteris for your great module wrapper.
What seems not to work is the h5file.visititems function.

Here is some minimal example code to reproduce this issue:
(it should print all given attributes of an h5 element,
replace "path_to_file" to any hdf5 file)

import h5pickle

def print_node_attributes(name, node):
        for k in node.attrs.keys():
            print(k)
                
with h5pickle.File(path_to_file, "r", skip_cache=False) as h5f:
    h5f.visititems(print_node_attributes)

I get this error:
RuntimeError: Object visitation failed (invalid object ID)

Do you have an idea on how to deal with that?
Thank you!

Hi, I think this is because we do not wrap the visititems function in this module.
Doing that would probably enable this usecase. I might take a look in a few weeks, or I'd be happy to accept a pull request.

Hi @fmfreeze,

I tried to look into your issue, but I cannot reproduce it with my (extremely simple) test HDF5 file.
Could you send me a sample file for which the above program fails?
