(set_attr): Ditto. * python/py-prettyprint.c (print_string_repr): use PyBytes methods instead of PyString methods if Python 3. (print_children): Skip push_dummy_python_frame call if Python 3. * python/py-symtab.c: Use PyVarObject_HEAD_INIT in initialization of type objects. (salpy_dealloc): Use Py_TYPE to call tp_free. * python/py-type.c: Use PyVarObject_HEAD_INIT in initialization of type objects. (field_dealloc): Use Py_TYPE to call tp_free. (typy_dealloc): Ditto. (type_object_as_number): Adjust struct initializations for differences in layout for Python 2 vs. Python 3. * python/py-utils.c (python_string_to_unicode): Omit non-Unicode string case for Python 3. (unicode_to_encoded_python_string): Shorten code (no functional change). (python_string_to_target_python_string): Comment that in Python 3 returned value is a Python "bytes" type. (gdbpy_is_string): Omit non-Unicode string check in Python 3. (gdb_py_object_from_longest): Omit non-long integer case in Python 3. (gdb_py_object_from_ulongest): Ditto. * python/py-value.c: Use PyVarObject_HEAD_INIT in initialization of type objects. (valpy_dealloc): Use Py_TYPE to call tp_free. (valpy_int): Omit function if Python 3. (convert_value_from_python): Use "%S" format (Python object as a string) if Python 3. (value_object_as_number): Adjust struct initializations for differences in layout for Python 2 vs. Python 3. * python/python-config.py: Adjust syntax for Python 3 compatibility. Include "sys.abiflags" string as part of python library name, if that attribute exists (Python 3). * python/python-internal.h (IS_PY3): Define if Python 3. (Py_TPFLAGS_HAVE_ITER, Py_TPFLAGS_CHECKTYPES): Define with placeholder value if Python 3. (PyInt_Check, PyInt_FromLong, PyInt_AsLong, PyString_FromString, PyString_Decode, PyString_FromFormat, PyString_Check): Define as analogous Python 3 API function if Python 3. (PyVarObject_HEAD_INIT): Define if not already defined. (Py_TYPE): Ditto. * python/python.c (eval_python_command): Omit Py_FlushLine call if Python 3. Check return values of all Python API calls for error. Supply dummy "python" and "python-interactive" commands if Python initialization failed. (_initialize_python): Convert argc to wchar_t** if Python 3. Add module initialization for Python 3. (finish_python_initialization): Pass wchar_t * argument to PySys_SetPath if Python 3. * python/lib/gdb/__init__.py: Define "reload" if Python 3. (_GdbFile): New class for common output file behavior. (GdbOutFile): Subclass from _GdbFile. (GdbOutputErrorFile): Ditto. (auto_load_packages): Adjust syntax for Python 3 compatibility. * python/lib/gdb/printing.py: Define basestr and int if Python 3. * python/lib/gdb/prompt.py: Use sorted() function rather than sort() method. * python/lib/gdb/command/explore.py: Define raw_input if Python 3. Adjust syntax for Python 3 compatibility. * python/lib/gdb/command/pretty_printers.py: Use sorted() function rather than sort() method. Adjust syntax for Python 3 compatibility. * python/lib/gdb/command/type_printers.py: Ditto. * doc/gdb.texinfo (Inferior.read_memory): Mention that the return value is a memoryview object if Python 3. --- gdb/python/py-value.c | 35 +++++++++++++++++++++++++++++++---- 1 file changed, 31 insertions(+), 4 deletions(-) (limited to 'gdb/python/py-value.c') diff --git a/gdb/python/py-value.c b/gdb/python/py-value.c index 6f67bdb..fd9d673 100644 --- a/gdb/python/py-value.c +++ b/gdb/python/py-value.c @@ -106,7 +106,7 @@ valpy_dealloc (PyObject *obj) Py_XDECREF (self->dynamic_type); - self->ob_type->tp_free (self); + Py_TYPE (self)->tp_free (self); } /* Helper to push a Value object on the global list. */ @@ -1140,6 +1140,7 @@ is_intlike (struct type *type, int ptr_ok) || (ptr_ok && TYPE_CODE (type) == TYPE_CODE_PTR)); } +#ifndef IS_PY3K /* Implements conversion to int. */ static PyObject * valpy_int (PyObject *self) @@ -1161,6 +1162,7 @@ valpy_int (PyObject *self) return gdb_py_object_from_longest (l); } +#endif /* Implements conversion to long. */ static PyObject * @@ -1335,9 +1337,14 @@ convert_value_from_python (PyObject *obj) value = value_copy (((value_object *) result)->value); } else +#ifdef IS_PY3K + PyErr_Format (PyExc_TypeError, + _("Could not convert Python object: %S."), obj); +#else PyErr_Format (PyExc_TypeError, _("Could not convert Python object: %s."), PyString_AsString (PyObject_Str (obj))); +#endif } if (except.reason < 0) { @@ -1439,7 +1446,9 @@ static PyNumberMethods value_object_as_number = { valpy_add, valpy_subtract, valpy_multiply, +#ifndef IS_PY3K valpy_divide, +#endif valpy_remainder, NULL, /* nb_divmod */ valpy_power, /* nb_power */ @@ -1453,12 +1462,31 @@ static PyNumberMethods value_object_as_number = { valpy_and, /* nb_and */ valpy_xor, /* nb_xor */ valpy_or, /* nb_or */ +#ifdef IS_PY3K + valpy_long, /* nb_int */ + NULL, /* reserved */ +#else NULL, /* nb_coerce */ valpy_int, /* nb_int */ valpy_long, /* nb_long */ +#endif valpy_float, /* nb_float */ +#ifndef IS_PY3K NULL, /* nb_oct */ - NULL /* nb_hex */ + NULL, /* nb_hex */ +#endif + NULL, /* nb_inplace_add */ + NULL, /* nb_inplace_subtract */ + NULL, /* nb_inplace_multiply */ + NULL, /* nb_inplace_remainder */ + NULL, /* nb_inplace_power */ + NULL, /* nb_inplace_lshift */ + NULL, /* nb_inplace_rshift */ + NULL, /* nb_inplace_and */ + NULL, /* nb_inplace_xor */ + NULL, /* nb_inplace_or */ + NULL, /* nb_floor_divide */ + valpy_divide /* nb_true_divide */ }; static PyMappingMethods value_object_as_mapping = { @@ -1468,8 +1496,7 @@ static PyMappingMethods value_object_as_mapping = { }; PyTypeObject value_object_type = { - PyObject_HEAD_INIT (NULL) - 0, /*ob_size*/ + PyVarObject_HEAD_INIT (NULL, 0) "gdb.Value", /*tp_name*/ sizeof (value_object), /*tp_basicsize*/ 0, /*tp_itemsize*/ -- cgit v1.1
