Here's an example I'm using to test:

#!/usr/bin/env python3

from pwn import *

def check_connection(p):
    print('p.proc.stdin.closed:', p.proc.stdin.closed)
    print('p.proc.stdout.closed:', p.proc.stdout.closed)
    print("p.connected('send'):", p.connected('send'))
    print("p.connected('recv')", p.connected('recv'))
    print("p.can_recv()", p.can_recv())
    print('')

p = process('/bin/ls')

check_connection(p)

p.interactive()

check_connection(p)

try:
    p.send(b'A')
except:
    pass

check_connection(p)

Output:

$ ./test-interactive.py

BrokenPipeError: [Errno 32] Broken pipe

So the EOFError happened in the middle of interactive() on the recv side, so I can't check for this before calling it. Essentially, I'd like interactive() to end if the recv end disconnects, without waiting for the send end to disconnect.

How to exit `interactive()` when EOF received? #2106
