From af68c874a6803b4e90b616077a602c0593719a1d Mon Sep 17 00:00:00 2001 From: Jeremy Hylton Date: Sat, 10 Dec 2005 18:50:16 +0000 Subject: Add const to several API functions that take char *. In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *. --- Modules/_bisectmodule.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) (limited to 'Modules/_bisectmodule.c') diff --git a/Modules/_bisectmodule.c b/Modules/_bisectmodule.c index 0d29462f6b..e40297d4c3 100644 --- a/Modules/_bisectmodule.c +++ b/Modules/_bisectmodule.c @@ -40,7 +40,7 @@ bisect_right(PyObject *self, PyObject *args, PyObject *kw) int lo = 0; int hi = -1; int index; - static char *keywords[] = {"a", "x", "lo", "hi", NULL}; + static const char *keywords[] = {"a", "x", "lo", "hi", NULL}; if (!PyArg_ParseTupleAndKeywords(args, kw, "OO|ii:bisect_right", keywords, &list, &item, &lo, &hi)) @@ -70,7 +70,7 @@ insort_right(PyObject *self, PyObject *args, PyObject *kw) int lo = 0; int hi = -1; int index; - static char *keywords[] = {"a", "x", "lo", "hi", NULL}; + static const char *keywords[] = {"a", "x", "lo", "hi", NULL}; if (!PyArg_ParseTupleAndKeywords(args, kw, "OO|ii:insort_right", keywords, &list, &item, &lo, &hi)) @@ -137,7 +137,7 @@ bisect_left(PyObject *self, PyObject *args, PyObject *kw) int lo = 0; int hi = -1; int index; - static char *keywords[] = {"a", "x", "lo", "hi", NULL}; + static const char *keywords[] = {"a", "x", "lo", "hi", NULL}; if (!PyArg_ParseTupleAndKeywords(args, kw, "OO|ii:bisect_left", keywords, &list, &item, &lo, &hi)) @@ -167,7 +167,7 @@ insort_left(PyObject *self, PyObject *args, PyObject *kw) int lo = 0; int hi = -1; int index; - static char *keywords[] = {"a", "x", "lo", "hi", NULL}; + static const char *keywords[] = {"a", "x", "lo", "hi", NULL}; if (!PyArg_ParseTupleAndKeywords(args, kw, "OO|ii:insort_left", keywords, &list, &item, &lo, &hi)) @@ -233,4 +233,3 @@ init_bisect(void) m = Py_InitModule3("_bisect", bisect_methods, module_doc); } - -- cgit v1.2.1
