parser_progress_callback() leaks the Python callback result.
File: tree_sitter/binding/parser.c
Function: parser_progress_callback
static bool parser_progress_callback(TSParseState *state) {
PyObject *result = PyObject_CallFunction((PyObject *)state->payload, "Ip",
state->current_byte_offset, state->has_error);
return PyObject_IsTrue(result);
}PyObject_CallFunction() returns a new reference. PyObject_IsTrue() only reads
the object; it does not steal or release it. The callback result should be
decref'd after the truth value is computed.
Suggested fix:
PyObject *result = PyObject_CallFunction(...);
if (result == NULL) {
return false;
}
int truth = PyObject_IsTrue(result);
Py_DECREF(result);
return truth > 0;
