   1 # Test framework from Git with modifications.
   2 #
   3 # Modifications Copyright (C) 2016,2017 Kyle J. McKay.  All rights reserved.
   4 # Modifications made:
   5 #
   6 #  * Many "GIT_..." variables removed -- some were kept as TESTLIB_..." instead
   7 #    (Except "GIT_PATH" is new and is the full path to a "git" executable)
   8 #
   9 #  * IMPORTANT: test-lib-main.sh SHOULD NOT EXECUTE ANY CODE!  A new
  10 #    function "test_lib_main_init" has been added that will be called
  11 #    and MUST contain any lines of code to be executed.  This will ALWAYS
  12 #    be the LAST function defined in this file for easy locatability.
  13 #
  14 #  * Added cmd_path, _?fatal, whats_the_dir, vcmp, getcmd, say_tap, say_color_tap,
  15 #    fail_, test_possibly_broken_ok_ and test_possibly_broken_failure_ functions
  16 #
  17 #  * Anything related to valgrind or perf has been stripped out
  18 #
  19 #  * Many other minor changes

1175 # to fail because file is supposed to be unreadable after a successful
1176 # chmod.  In an environment (i.e. combination of what filesystem is
1177 # being used and who is running the tests) that lacks SANITY, you may
1178 # be able to delete or create a file when the containing directory
