Subject: [OASIS Issue Tracker] (MQTT-381) 3.3.1.3 RETAIN - comments
Brian Raymor created MQTT-381: --------------------------------- Summary: 3.3.1.3 RETAIN - comments Key: MQTT-381 URL: https://issues.oasis-open.org/browse/MQTT-381 Project: OASIS Message Queuing Telemetry Transport (MQTT) TC Issue Type: Bug Components: edits Affects Versions: 5, wd10 Reporter: Brian Raymor Priority: Minor Fix For: 5, wd10 Rather than describing mechanisms (if this bit is set in this control packet), could we simplify these cases throughout the document? For example: 1632 If the Server included Retain Available in its CONNACK response to a Client with it’s value set to 0 and it 1633 receives a PUBLISH Packet with the RETAIN flag is set to 1 might be easier to read as: If the server does not support message retention (see Retain Available section) and receives a PUBLISH Packet with the Retain Flag set to 1, then ka-boom. 2.the last retained message [is] sent to the Client with its RETAIN flag set to 1. 1636 When a new non-shared subscription is established, the last retained message, if any, on each matching 1637 topic name are sent to the Client. These messages are sent with the RETAIN flag set to 1. 3. The Retain Handling Subscription Option controls which retained messages are sent. 1637 ... Which 1638 retained messages are sent is controlled by the Retain Handling Subscription Option. 4. , [the] Server MUST NOT 1644 • If Retain Handling is set to 2, The Server MUST NOT send retained messages at the time of the 1645 subscribe. 5. If the server receives a PUBLISH Packet with the RETAIN=1 and QoS=0, it SHOULD store the message as the new retained message for that topic. It MAY also choose to discard it ... 1647 If the Server receives a PUBLISH Packet with the RETAIN flag set to 1, and QoS 0 it SHOULD store the 1648 new QoS 0 message as the new retained message for that topic, but MAY choose to discard it at any 1649 time. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
