From a32df9b6f4e997cb1565f90eaa721266790590ff Mon Sep 17 00:00:00 2001 From: David Gibson Date: Mon, 12 Sep 2022 20:56:16 +1000 Subject: test: Allow a tmux pane to watch commands executed in contexts We're moving to a new way of the tests dispatching commands to running in contexts (host, guest, namespace, etc.). As we make this transition, though, we still want the user to be able to watch the commands running in a context, as they previously could from the commands issued in the pane. Add a helper to set up a pane to watch a context's log to allow this. In some cases we currently issue commands from several different logical contexts in the same pane, so allow a pane to watch several contexts at once. Also use tail's --retry option to allow starting the watch before we've initialized the context which will be useful in some cases.
