TorPlugin socket timeout
There is a socket timeout in the Tor plugin, after 30 seconds of inactivity, that prevents user from communicating more than once over the mobile network. Connection between the devices is not re-established.
Reproduce:
- Two devices with connected contacts, A and B
- Using only the mobile network, A chats with B and vice versa.
- Close Briar and "lock" both devices by pressing the power button (don't turn off).
- Unlock both devices after ~60 seconds (I think the timeout is set at 30 seconds) and try to chat with both A and B. Notice that no messages will be received by the other user and the "clock" symbol remains indefinitely in place.
You can re-establish connection by turning on WiFi on both devices or bluetooth and notice that then the messages are sent instantly.
Following is the error message that I got:
