From: Mathieu Desnoyers Date: Tue, 2 May 2017 14:37:28 +0000 (-0400) Subject: Fix: lttng-live: send HUP reply when per-PID streams are gone X-Git-Tag: v2.10.0-rc1~9 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=797bc362b6845f7e8f50922f53fc4683c573fc55;p=lttng-tools.git Fix: lttng-live: send HUP reply when per-PID streams are gone Currently, the "HUP" reply (hung up) is only sent when a session destroy is performed and all data has been sent. However, with per-pid buffers, application can come and go during the tracing session, so we need to send the HUP reply for each individual stream that is gone.
