  17 # Test parallel automake execution.
  18
  19 # There are several hypotheses to be tested:  Independently of the number
  20 # of threads used by automake,
  21 # 0) the generated Makefile.in files must be identical without --add-missing,
  22 # 1) the Makefile.in that distributes auxiliary files must be generated
  23 #    after all other ones, so all installed aux files are caught,
  24 # 2) normal automake output should have identical content and be ordered
  25 #    in the same way, when --add-missing is not passed, or when
  26 #    --add-missing is passed but there are no concurrent file requirements
  27 #    (i.e., two Makefile.am files call for the same needed aux file)
  28 # 3) normal automake output should be identical and ordered in the same way
  29 #    with --add-missing, even with concurrent file requirements, and the
  30 #    installation of aux files should be race-free,
  31 # 4) warning and normal error output should be identical, in that duplicate
  32 #    warnings should be omitted in the same way as without threads,
  33 # 5) fatal error and debug messages could be identical.  This is not
  34 #    intended, though.
  35 #
  36 # This test checks (0), (1), and (2).  See sister tests for further coverage.
