Cannot directly close dsch storage files

[JonasHoelscher]

If a dsch storage is created the file will be created and blocked as long as the storage object exists. This is a problem when, for example, creating integration tests: When using dsch to create temporary files in a test environment, the temporary files cannot be removed afterwards.

Quick fix

storage = dsch.create(file, schema)
storage.save()
storage._storage.close()

This closes the file using the internal h5py object. Therefore the user needs to be aware of the open file handlers which he didn't even open.

Have you tried deleting the storage object (i.e. del storage)? We do not have explicit object teardown, I think, but as long as you don't keep child object references, that should close the file.
