  18 # Description: In tar 1.26 listed-incremental with -C and absolute path
  19 # would malfunction under certain conditions due to buggy filename
  20 # normalization.
  21 #
  22 # The value returned by normalize_filename() is used to populate the "caname"
  23 # field in both the "directory" structure in incremen.c and the "name"
  24 # structure in names.c, and in both cases that field is then used in the
  25 # "hash" and "compare" functions for the related hash tables.  Thus, the
  26 # fact that the returned value doesn't reflect the operation of previous
  27 # "-C" options means that it's possible for two different directories to
  28 # be given the same "caname" value in the hashed structure and thus end up
  29 # being confused with each other.
  30 #
  31 # The bug is triggered when dumping both relative paths after -C and
  32 # absolute paths that match the process' current working directory.
