The tp_new signature declared no minimum and no positional-only parameters, so _tuplegetter(0) and _tuplegetter() built a descriptor from defaults, and index and doc were accepted as keywords. CPython requires exactly two positional arguments and rejects keywords. Signed-off-by: Jeongseop Lim <[email protected]>
Both functions were added to the math module in Python 3.11 and were missing, so math.cbrt and math.exp2 raised AttributeError. cbrt uses Math.cbrt; exp2 uses Math.pow(2.0, x) and raises OverflowError on an infinite result from a finite argument, as exp does. Enable CPython's testCbrt and testExp2, which now pass. Signed-off-by: Jeongseop Lim <[email protected]>
The constructor took only cls, so _thread.RLock(0) and threading.RLock(0) raised TypeError. CPython 3.12 and 3.13 accept and ignore any arguments, and threading.RLock passes them on after a DeprecationWarning that announces the removal for 3.15. Signed-off-by: Jeongseop Lim <[email protected]>
The types were registered under the names Reader and Writer, so type(csv.reader([])) printed as <class '_csv.Reader'>. In CPython the types are named reader and writer and are exposed in _csv under the aliases Reader and Writer. Rename them, keep the module name, and add the aliases.
