What am I missing?
_file=file
class file(_file): ...
def flush(self, wait=0):
super().flush(self)
if wait < 0.25:
return
if wait < 0.5 and os.fdatasync:
os.fdatasync(self.fileno())
return
os.fsync(self.fileno())
if wait < 0.75:
return
if os.ffullsync:
os.ffullsync(self.fileno())
(To be honest, I'm not even seeing why it couldn't be done in
Objects/fileobject.c, though I realize extension modules would need to
go through the python interface to take advantage of it.)
