Description

Not actually sure how we currently behave.

Do we see the data objects and inject files with incorrect layouts? Do we ignore the data objects entirely?

In general we should be iterating over all objects (no matter the namespace) and creating linkage with the proper pool_namespace set if the objects were not in the default namespace.

History

#1 Updated by Zheng Yan about 2 years ago

the backtrace objects are always in default namespace. I think data scan tool can't calculate correct size for files in non-default namespace
