Subject: [PATCH] Lib/pty.py: handle stdin I/O errors same way as master I/O
|
|
errors
|
|
|
|
reading stdin can throw the same I/O errors as reading from master fd does,
|
|
e.g. when running 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
|
|
|
|
So let's treat both channels the same.
