   8 # Test the deterministic behavior of the src.ctf.fs component versus the
   9 # ordering of the given input paths.
  10 #
  11 # In presence of multiple copies of the same packet, we want it to pick the
  12 # copy of the packet to read in a deterministic fashion.
  13 #
  14 # This test is written assuming the specific implementation of the src.ctf.fs
  15 # component class, which sorts its input paths lexicographically.
  16 #
  17 # There are three traces (a-corrupted, b-not-corrupted and c-corrupted) with the
  18 # same UUID and the same packet, except that this packet is corrupted in
  19 # a-corrupted and c-corrupted. In these cases, there is an event with an
  20 # invalid id.  When reading these corrupted packets, we expect babeltrace to
  21 # emit an error.
  22 #
  23 # When reading a-corrupted and b-not-corrupted together, the copy of the packet
  24 # from a-corrupted is read, and babeltrace exits with an error.
  25 #
  26 # When reading b-not-corrupted and c-corrupted together, the copy of the packet
  27 # from b-not-corrupted is read, and babeltrace executes successfully.
