Subject: [OASIS Issue Tracker] (MQTT-474) If the packet has a zero length Topic Name field ...which Reason Code is appropriate?
[ https://issues.oasis-open.org/browse/MQTT-474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=66657#comment-66657 ] Ken Borgendale commented on MQTT-474: ------------------------------------- The original discussion of 0x94 (Topic Alias invalid) is that it is outside of the valid range (>Maximum Topic Alias) and it is so documented. I do not see any requirement for this change. > If the packet has a zero length Topic Name field ...which Reason Code is appropriate? > ------------------------------------------------------------------------------------- > > Key: MQTT-474 > URL: https://issues.oasis-open.org/browse/MQTT-474 > Project: OASIS Message Queuing Telemetry Transport (MQTT) TC > Issue Type: Bug > Components: core > Affects Versions: 5, wd14 > Reporter: Konstantin Dotchkoff > Priority: Minor > Fix For: 5, wd14 > > > This issue was originally reported in MQTT-417. > Line 2037-2039 > "3) If the receiver does not already have a mapping for this Topic Alias > a) If the packet has a zero length Topic Name field it is a Protocol Error and the receiver uses DISCONNECT with Reason Code of 0x82 (Protocol Error) as described in section 4.13." > Why not use Return Code of 0x94 Topic Alias invalid? -- This message was sent by Atlassian JIRA (v6.2.2#6258)
