Terry J. Reedy added the comment:
I am presuming 2.7 has same problem since it has same code.
The patch appears to give PyShell.close a return value it did not have before.
Perhaps remove the return?
I am slightly puzzled: self.pollinterval is 50 (millisecs). If reducing the
wait from 100 to 1 makes the problem constant, why does reducing it to 0 make
it go away? What have I misunderstood?
Trying to test on Windows in a 3.3 build, I get the following with or without
the patch:
>>> exit()
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
exit()
File "D:\Python\dev\py33\lib\site.py", line 380, in __call__
raise SystemExit(code)
SystemExit: None
--------------------------------
def __call__(self, code=None):
# Shells like IDLE catch the SystemExit, but listen when
# stdin wrapper is closed.
try:
fd = -1
if hasattr(sys.stdin, "fileno"):
fd = sys.stdin.fileno()
if fd != 0:
# Don't close stdin if it wraps fd 0
sys.stdin.close()
except:
pass
raise SystemExit(code)
>>>
---------------------------
<bare excepts are evil>
----------------------------
>>> import sys
>>> hasattr(sys.stdin, "fileno")
True
>>> sys.stdin.fileno
<built-in method fileno of PseudoInputFile object at 0x02893C08>
>>> sys.stdin.fileno()
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
sys.stdin.fileno()
io.UnsupportedOperation: fileno
The problem is that PseudoInputFile subclasses PseudoFile which now subclasses
TestIOBase without overriding .fileno(), which raises the above. This is from
#9290.
Bottom line: I believe quit() and exit() are broken in the current 2.7, 3.2,
and 3.3 rc's. I will report a possible quick fix on pydev.
