# Test printing roots that refer to NULL pointers. # Since mozilla.prettyprinters.Pointer declines to create pretty-printers # for null pointers, GDB built-in printing code ends up handling them. But # as of 2012-11, GDB suppresses printing pointers in replacement values: # see: http://sourceware.org/ml/gdb/2012-11/msg00055.html # # Thus, if the pretty-printer for JS::Rooted simply returns the referent as # a replacement value (which seems reasonable enough, if you want the # pretty-printer to be completely transparent), and the referent is a null # pointer, it prints as nothing at all. # # This test ensures that the JS::Rooted pretty-printer doesn't make that # mistake. # flake8: noqa: F821 gdb.execute("set print address on") run_fragment("Root.null") assert_pretty("null", "0x0")
