Hi Detlef,
This looks like a bug in h5repack. Can you give us your file?
Please send it to:

If it is too large to send I can give you instructions for uploading it, as
well.
Thanks!

Subject: [Hdf-forum] H5repack, dimension scales with custom attributes
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
