Subject: cli: mimic behavior of BT1 when trying to attach to live session
X-Git-Url: http://git.efficios.com/?p=deliverable%2Fbabeltrace.git;a=commitdiff_plain;h=136906ad574dff33d6266173e577e3f2a9518d1f

cli: mimic behavior of BT1 when trying to attach to live session

In Babeltrace 1, when trying to attach to a LTTng live session the
`babeltrace` command would exit with status 0 (SUCCESS) if it
successfully connected to the relay daemon _even if_ it did not find the
requested session.

To mimic the behavior of BT1, we set the `session-not-found-action`
parameter to "end". This makes the message iterator of an lttng-live
component return a END status if the requested session is not found
on the relay daemon and makes the cli return gracefully with SUCCESS.
