A convention in the Python layer is that raising a gdb.GdbError will not print the Python stack -- instead the exception is treated as any other gdb exception. PR python/18852 asks that this treatment be extended the the get_set_value method of gdb.Parameter. This makes sense, because it lets Python-created parameters act like gdb parameters. 2018-09-23 Tom Tromey <tom@tromey.com> PR python/18852: * python/py-param.c (get_set_value): Use gdbpy_handle_exception. gdb/doc/ChangeLog 2018-09-23 Tom Tromey <tom@tromey.com> PR python/18852: * python.texi (Parameters In Python): Document exception behavior of get_set_string. gdb/testsuite/ChangeLog 2018-09-23 Tom Tromey <tom@tromey.com> PR python/18852: * gdb.python/py-parameter.exp: Add test for parameter that throws on "set".
