[New-bugs-announce] [issue22439] subprocess.PIPE.stdin.flush() causes to hang while subprocess.PIPE.stdin.close() not

[Sworddragon]

New submission from Sworddragon:

On sending something to stdin of a process that was called with subprocess (for example diff) I have figured out that all is working fine if stdin is closed but flushing stdin will cause a hang (the same as nothing would be done). In the attachments is a testcase that shows this problem. If executed the application will hang but if #pipe.stdin.close() will be uncommented (and optionally pipe.stdin.flush() commented out) all is working fine.
