* bpo-35883: Py_DecodeLocale() escapes invalid Unicode characters (GH-24843) ↵Miss Islington (bot)2021-03-291-4/+5
| | | | | | | | | | | | | | | | | (GH-24906) Python no longer fails at startup with a fatal error if a command line argument contains an invalid Unicode character. The Py_DecodeLocale() function now escapes byte sequences which would be decoded as Unicode characters outside the [U+0000; U+10ffff] range. Use MAX_UNICODE constant in unicodeobject.c.

* [3.8] bpo-41909: Enable previously disabled recursion checks. (GH-22536) ↵Serhiy Storchaka2020-10-042-4/+0
| | | | | | | | | | | | | | | (GH-22551) Enable recursion checks which were disabled when get __bases__ of non-type objects in issubclass() and isinstance() and when intern strings. It fixes a stack overflow when getting __bases__ leads to infinite recursion. Originally recursion checks was disabled for PyDict_GetItem() which silences all errors including the one raised in case of detected recursion and can return incorrect result. But now the code uses PyDict_GetItemWithError() and PyDict_SetDefault() instead. (cherry picked from commit 9ece9cd65cdeb0a1f6e60475bbd0219161c348ac)

| | | | | | | | | | | | | | | | | | gcc -Wcast-qual turns up a number of instances of casting away constness of pointers. Some of these can be safely modified, by either: Adding the const to the type cast, as in: - return _PyUnicode_FromUCS1((unsigned char*)s, size); + return _PyUnicode_FromUCS1((const unsigned char*)s, size); or, Removing the cast entirely, because it's not necessary (but probably was at one time), as in: - PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno); + PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno); These changes will not change code, but they will make it much easier to check for errors in consts (cherry picked from commit e6be9b59a911626d6597fe148c32f0342bd2bd24) Co-authored-by: Andy Lester <andy@petdance.com>

| | | | | | | | | | | | | | | | The implementation of weakref.proxy's methods call back into the Python API using a borrowed references of the weakly referenced object (acquired via PyWeakref_GET_OBJECT). This API call may delete the last reference to the object (either directly or via GC), leaving a dangling pointer, which can be subsequently dereferenced. To fix this, claim a temporary ownership of the referenced object when calling the appropriate method. Some functions because at the moment they do not need to access the borrowed referent, but to protect against future changes to these functions, ownership need to be fixed in all potentially affected methods..
