InterpreterPoolExecutor doesn't respect "thread_name_prefix" #125920
Description
Activity
Confirmed on the main branch, but this isn't related to
InterpreterPoolExecutor.ipe_executor._thread_name_prefixdoes appear to be set to the correct value, and theThreadobject name is the right value when checking it directly withipe_executor._threads.The problem is that thread names aren't pushed down to subinterpreters, which very well might be a wontfix depending on the complexity of the change. Here's a reproducer for that:
import _interpreters import threading source = """ import threading print(threading.current_thread().name) # Dummy-1 """ def main(): interp = _interpreters.create() print(threading.current_thread().name) # Hello _interpreters.run_string(interp, source) threading.Thread(target=main, name="hello").start()
cc @ericsnowcurrently, it might be better to just note this when subinterpreters get documented better. (Though, if that's the case,
thread_name_prefixshould just get removed fromInterpreterPoolExecutor.)
Bug report
Bug description:
InterpreterPoolExecutor takes a thread_name_prefix parameter, but it doesn't propagate to the underlying subinterpreter.
