Hi there,
I'm not sure if I'm doing something wrong, but I have a strange behavior of h5repack.
I am creating a HDF5 file with a simple dataset and attach a dimension scale dataset to the first dimension of that dataset. Because my Data can be interpreted in different ways, I need to attach some custom attributes to the scale dataset, for example "UNITS" or "SUB_CLASS".
So far so good, writing that file works as expected, HDFView shows the contents correctly, reading the file back works fine.
When I run h5repack with that file however, I get the following output:
HDF5-DIAG: Error detected in HDF5 (1.8.15-patch1) thread 0:
#000: C:\autotest\HDF518ReleaseRWDITAR\src\H5A.c line 259 in H5Acreate2(): unable to create attribute
major: Attribute
minor: Unable to initialize object
#001: C:\autotest\HDF518ReleaseRWDITAR\src\H5Aint.c line 167 in H5A_create(): attribute already exists
major: Attribute
minor: Object already exists
h5repack: <myfile.h5>: Could not copy data to: myfile-repacked.h5
When I debug into the h5repack tool, I localized the point at which some error occurs.
It is, when h5repack tries to create one of my custom attributes of the dimension scale dataset (h5repack_refs.c, line 599, attr_out = H5Acreate2(...)) ==> attr_out = -1, called from do_copy_refobjs()
Has anybody some idea, what could go wrong ?
If it helps I could post the dumps of the original and the repacked files...
Best regards,
Detlef
