Add fallback for missing H5Pget_dxpl_mpio #1121

Closed mkitti closed 9 months ago

mkitti commented 9 months ago

When trying to iterate through properties, one finds the xfer property of a HDF5.Dataset. This in turn discovers the property dxpl_mpio which may fail if H5Pget_dxpl_mpio does not exist.

The commit is a temporary fix, but may need be reworked perhaps at a higher level in properties.jl.

On second thought this is probably not a good idea. The error should be handled at the application level.
