When decoding such selection via H5Sdecode(), + the number of elements in the decoded dataspace is not the same as + what is encoded. This problem exists for H5S_SEL_HYPER and + H5S_SEL_POINTS encoding. - (HDFFV-9947, VC, 2017/11/28) + The cause of the problem is because the library uses 32 bits to + encode counts and block offsets for the selection. + The solution is to use the original 32 bit encodings if possible, + but use a different way to encode selection > 32 bits when needed. + See details in the RFC: H5Sencode/H5Secode Format Change. + + (VC - 2017/11/28, HDFFV-9947) - filter plugin handling in H5PL.c and H5Z.c |
