[jira] [Commented] (PROTON-116) Proton sends explicit disposition
for pre-settled messages
[ https://issues.apache.org/jira/browse/PROTON-116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13490737#comment-13490737 ]
Rafael H. Schloming commented on PROTON-116:
--------------------------------------------
It's not illegal to send the spurious disposition, however you're correct that it's not needed.

> Key: PROTON-116
> URL: https://issues.apache.org/jira/browse/PROTON-116
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.2
> Reporter: Ted Ross
> Priority: Minor
>
> When proton sends pre-settled messages (the settled flag is set in the transfer), it follows up with an explicit disposition frame for the message.
> I believe this disposition update is spurious and unneeded, though I haven't found a definitive statement one way or the other in the protocol specification.
