select_pane not working correctly with multiple sessions about libtmux HOT 2 OPEN

Hi!

Can you restate some of the above? It isn't clear to me.

On a side note: PRs, especially ones with good tests, are also welcome

Hey tony. Sure.

As an example, I have the following

session = None
sessions = self._server.attached_sessions
if len(sessions) > 1:
    log.info('There are more than 1 sessions active. Unable to detect active one.')
elif len(sessions) == 1:
    session = sessions[0]
else:
    log.info('No active sessions found.')

session.attached_window.select_pane(3)

I use only one client attached to one session, which I make sure is true.

The session is always correct (the one I am active in).
However, running select_pane(3) on the attached window always switches the pane in one specific session (even when I am active in another and the session variable is correct.

The select_pane method ultimately calls the window function self.cmd here: https://github.com/tmux-python/libtmux/blob/master/src/libtmux/window.py#L163

self.cmd("select-pane", "-t%s" % target_pane)

(select-pane -t3)

This ends up in the server function self.server.cmd here: https://github.com/tmux-python/libtmux/blob/master/src/libtmux/window.py#L141

self.server.cmd(cmd, *args, **kwargs)

(select-pane -t3)

Which then ends up here: https://github.com/tmux-python/libtmux/blob/master/src/libtmux/server.py#L177

tmux_cmd(*cmd_args, **kwargs)

which will probably end up in calling tmux select-pane -t3.

=> This does not switch the pane in the active session window, but in another one.

I just tested a bit. When I run the shell command tmux select-pane -t3 in any session it correctly switches the pane.

Could it be that, because the python program (doing the switching) is running in another session, it always switches panes in that session?
^ I just tested above theory: and yes, that is the case.

=> I think it would be wise to always pass the session_id and window_id with the -t argument!?
