Subject: [OASIS Issue Tracker] (MQTT-290) Session Expiry Will message.
[ https://issues.oasis-open.org/browse/MQTT-290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=63614#comment-63614 ] Jonathan Levell commented on MQTT-290: -------------------------------------- Discuss in the Sept2016 TC face to face seems to be moving towards consensus around having a timer on a will message, and the will message is sent at the minimum(will timeout, session timeout). Consensus wasn't complete but largely agreed. Allowing a special return code that keeps will message allows the will message to be used to mark session expiry. > Session Expiry Will message. > ---------------------------- > > Key: MQTT-290 > URL: https://issues.oasis-open.org/browse/MQTT-290 > Project: OASIS Message Queuing Telemetry Transport (MQTT) TC > Issue Type: Improvement > Components: futures > Affects Versions: 5 > Reporter: Andrew Banks > Assignee: Andrew Banks > > The Will message is created on CONNECT and is published by the Server > if the network connection is lost without a DISCONNECT packet being > processed. > Jira 249 introduces the idea of a Session expiry interval, such that a > session can be deleted by the client and server some time after > an Network disconnection. > This Jira discusses whether another Will message should flow when > the client's Session is deleted. Possible approaches include: > 1) Allowing a second Session Expiry will message to flow in the CONNECT packet, > in addition to the current Network Disconnection will message, > and publishing this when the session either expires or is deleted by an administrator. > 2)Signaling via a flag in the CONNECT packet that the Will message > should be published when the session expires or is deleted, > instead of when the network is disconnected. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
