From 7ccbca93a27e22f0b06316b0d9760fbf7b19cbda Mon Sep 17 00:00:00 2001 From: Armin Rigo Date: Wed, 4 Oct 2006 12:17:45 +0000 Subject: Forward-port of r52136,52138: a review of overflow-detecting code. * unified the way intobject, longobject and mystrtoul handle values around -sys.maxint-1. * in general, trying to entierely avoid overflows in any computation involving signed ints or longs is extremely involved. Fixed a few simple cases where a compiler might be too clever (but that's all guesswork). * more overflow checks against bad data in marshal.c. * 2.5 specific: fixed a number of places that were still confusing int and Py_ssize_t. Some of them could potentially have caused "real-world" breakage. * list.pop(x): fixing overflow issues on x was messy. I just reverted to PyArg_ParseTuple("n"), which does the right thing. (An obscure test was trying to give a Decimal to list.pop()... doesn't make sense any more IMHO) * trying to write a few tests... --- Python/errors.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'Python/errors.c') diff --git a/Python/errors.c b/Python/errors.c index 7b7105104a..66a734eb15 100644 --- a/Python/errors.c +++ b/Python/errors.c @@ -551,7 +551,8 @@ PyErr_NewException(char *name, PyObject *base, PyObject *dict) goto failure; } if (PyDict_GetItemString(dict, "__module__") == NULL) { - modulename = PyString_FromStringAndSize(name, (int)(dot-name)); + modulename = PyString_FromStringAndSize(name, + (Py_ssize_t)(dot-name)); if (modulename == NULL) goto failure; if (PyDict_SetItemString(dict, "__module__", modulename) != 0) -- cgit v1.2.1
