From: Jérémie Galarneau Date: Mon, 10 Feb 2020 23:35:27 +0000 (-0500) Subject: sessiond: notification: introduce the notion of 'active' client X-Git-Tag: v2.13.0-rc1~503 X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=1b5edb83504a933f6f5a1b07d574f8c6cf2e0e4e;hp=1b5edb83504a933f6f5a1b07d574f8c6cf2e0e4e sessiond: notification: introduce the notion of 'active' client Since notification_clients are now accessed from multiple threads, it is possible for a thread to access a client while it is being "cleaned-up" following an error. The 'active' communication flag allows a check to be performed before any communication is attempted with a client. The communication is considered 'active' once the handshake has been performed. It is considered 'inactive' if a fatal protocol error occurs. Signed-off-by: Jérémie Galarneau Change-Id: If16f83ef12fe9a6ef597ae464867011811389177 ---
