            Bug ID: 31248
           Summary: debuginfod_find_* may return fd with file-offset at
                    end
           Product: elfutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: debuginfod

  Target Milestone: ---

During the srcfiles test case diagnosis, studying the reason for occasional
0-length files, found something funky about the debuginfod_find_FOO api.

It appears possible for first-time-downloaded files to result in FDs that w=
ere
freshly written into by curl, with the file offset positioned right at the =
end.
 We should lseek(2) to the front.  Clients would expect to be able to read =
it,
as opposed to an insta-EOF.
