miniplumber: domain socket errors? #905

Open jasoncontrib opened 7 years ago

jasoncontrib commented 7 years ago

Intermittent errors occur when using pipes via the domain socket; some invocations of the pipe command over the domain socket, e.g. echo "hello" | minimega -pipe foo cause errors such as the following:

2017/04/12 17:50:57 ERROR command_socket.go:76: write unix /tmp/minimega/minimega->@: use of closed network connection
2017/04/12 17:50:58 ERROR command_socket.go:169: read unix /tmp/minimega/minimega->@: read: connection reset by peer
2017/04/12 17:50:58 ERROR command_socket.go:76: write unix /tmp/minimega/minimega->@: use of closed network connection

This does not occur when not using the domain socket, e.g. when executing pipe foo "hello" in the main minimega CLI, or when using the domain socket with a non-miniplumber command, e.g. minimega -e vm info

This is a known race in miniclient. Do you have any data loss? The -e interface will show this too, though evidently less often, if you spam it.
