[tor/maint-0.4.3] conn: Remove assert on new listener connection when retrying
by nickm＠torproject.org 07 Oct '20

07 Oct '20

commit ea339227c27c03d7ced9e526d9e945708f432b22 Author: David Goulet <dgoulet(a)torproject.org> Date: Tue Sep 1 09:54:48 2020 -0400 conn: Remove assert on new listener connection when retrying Opening a new listener connection can fail in many ways like a bind() permission denied on a low port for instance. And thus, we should expect to handle an error when creating a new one instead of assert() on it. To hit the removed assert: ORPort 80 KeepBindCapabilities 0 Start tor. Then edit torrc: ORPort <some-IP>:80 HUP tor and the assert is hit.
