[issue45223] test_spawn_doesnt_hang (test.test_pty.PtyTest) fails when stdin isn't readable

[Alexander Kanavin]

New submission from Alexander Kanavin :

I am observing the following under yocto's test harness:
==
ERROR: test_spawn_doesnt_hang (test.test_pty.PtyTest)
--
Traceback (most recent call last):
  File "/usr/lib/python3.10/test/test_pty.py", line 316, in 
test_spawn_doesnt_hang
pty.spawn([sys.executable, '-c', 'print("hi there")'])
  File "/usr/lib/python3.10/pty.py", line 181, in spawn
_copy(master_fd, master_read, stdin_read)
  File "/usr/lib/python3.10/pty.py", line 157, in _copy
data = stdin_read(STDIN_FILENO)
  File "/usr/lib/python3.10/pty.py", line 132, in _read
return os.read(fd, 1024)
OSError: [Errno 5] Input/output error


The same tests runs fine in a regular console.
