H5Aopen_by_name bug

Hdf-forum archives
1

I'm having a problem using H5Aopen_by_name with a group name. I'm using
HDF5 1.8.16.

Doesn't work:
    auto aid = H5::H5Aopen_by_name(file_id, "g1", "a1", H5::H5P_DEFAULT,
H5::H5P_DEFAULT);
    int v = 6;
    auto r = H5::H5Awrite(aid, type_id, &v); // returns -1

Works:
    auto group_id = H5::H5Gopen(file_id, "g1", H5::H5P_DEFAULT);
    auto aid = H5::H5Aopen_by_name(group_id, ".", "a1", H5::H5P_DEFAULT,
H5::H5P_DEFAULT);
    int v = 6;
    auto r = H5::H5Awrite(aid, type_id, &v); // returns 0

Hi David,

I was able to reproduce this and entered bug HDFFV-9680 for this issue.
H5Aread worked but H5Awrite failed. Both work if using H5Aopen_by_name(id, “.”, ….).

Thanks!

Thanks. Is there a way I can follow this in your bug tracker (I can't find
it) so I can patch my lib when a solution is found?

Unfortunately, our bug tracker is not open at this point. We are working on changing this after we move HDF5 to Git and to the new versions of Atlassian tools (in progress). I will update FORUM when HDF5 JIRA project becomes public.

Once again, thank you for your patience.
