@pasenor I don't have a good way to check the ssh connection locally, I trust you've done the necessary testing. The code looks good. I merged some older PRs, so now the code has some conflicts with master. Can you please resolve them? |
|
Yes, I have tested the SSH connection. I wonder how to add it to the test suite. Looking at the paramiko documentation, they have a server implementation, maybe we can try to use it for testing the SSH-related stuff? (not in this PR, just thinking out loud) |

On rebase this should become a little different, like
if port or (host and host != 'localhost') or self.ssh_client:
socket = ''

Side note: the list_ssh_config feature is unreliable if the SSH config file uses certain features such as Match. Listing the hosts is not really in the scope of a tool such as mycli, and we ought to consider removing it.

We could still log these values, if we wanted to, right?

Description
We were spawning a separate SSH connection for the completer thread. It seems unnecessary since we can just open a second channel on the same connection.
