Bug report
In #127524, @mpage suggested adding an assert to check that the list object is locked when calling ensure_shared_on_resize. This uncovers a few more locking issues.
Additionally, we may return out of the critical section without unlocking here:
|
Py_BEGIN_CRITICAL_SECTION(a); |
|
Py_ssize_t n = PyList_GET_SIZE(a); |
|
PyObject *copy = list_slice_lock_held(a, 0, n); |
|
if (copy == NULL) { |
|
return -1; |
|
} |
|
ret = list_ass_slice_lock_held(a, ilow, ihigh, copy); |
|
Py_DECREF(copy); |
|
Py_END_CRITICAL_SECTION(); |
