Ya, it's clearly best for `current_thread()` to deliver consistent results.

Tim, any opinion on this one?  Do you agree it's an actual bug (if a bit 
obscure)?

[issue31516] current_thread() becomes "dummy" thread during shutdown

2017-09-19 Thread Antoine Pitrou 

Antoine Pitrou added the comment:

The main thread being marked "stopped" at shutdown might be an obscure feature 
(as hinted in the comments for threading._shutdown()).  However, 
current_thread() should definitely not return a separate DummyThread instance.

[issue31516] current_thread() becomes "dummy" thread during shutdown

2017-09-19 Thread Antoine Pitrou 

New submission from Antoine Pitrou:

Attaching reproducer.  During interpreter shutdown, threading.main_thread() 
gets marked "stopped" (while it's obviously still running), while 
threading.current_thread() returns a DummyThread instance with the same ident 
as the main thread.

$ ./python mainthread.py 
-- before shutdown --
GC in thread <_MainThread(MainThread, started 140359122872064)>
main thread is <_MainThread(MainThread, started 140359122872064)>
-- during shutdown --
GC in thread <_DummyThread(Dummy-1, started daemon 140359122872064)>
main thread is <_MainThread(MainThread, stopped 140359122872064)>
