CSV text reader does not handle duplicate header names

    XMLWordPrintableJSON

    Details

      Description

      Consider the following CSV file:

      h,h,h
      a,b,c
      d,e,f
      

      Parse this with the CSV storage plugins to parse headers. The result:

      2 row(s):
      h
      c
      f
      

      Expected a runtime error for the duplicate column names, or automatic "uniqification" of the names. Certainly did not expect the first two columns to be dropped.
