Robbie Gemmell created PROTON-940:
-------------------------------------
Summary: provide the session initial incoming window via Begin
rather than sending a separate Flow
Key: PROTON-940
URL: https://issues.apache.org/jira/browse/PROTON-940
Project: Qpid Proton
Issue Type: Bug
Components: proton-j
Affects Versions: 0.9.1, 0.9, 0.8
Reporter: Robbie Gemmell
Assignee: Robbie Gemmell
Fix For: 0.10
When a session is created, a Begin frame is sent. One of the fields on the
frame is the initial incoming window. Instead of populating the field, Proton-J
currently sets it to 0 but then immediately discovers the window is 0 and sends
a seperate Flow frame (in the same transport output sas the Begin frame)
changing the window to the actual calculated value.
This result is equivalent in the end and allowed by the protocol, but is not
particularly obvious behaviour and is different than proton-c. The initial
incoming window value should be conveyed in the Begin frame instead, removing
need for the immediate Flow.
