Re: [ws-tx] Issue 092 - WS-BA: specify 'presume compensate' assumption

[Mark Little <mark.little@jboss.com>]

To add further confusion to this ... in the minutes of the f2f is appears as though no decision was taken on presumed-nothing versus presumed-abort/compensate, but that:

ACTION: Ram : To submit text on presumed-nothing or presumed-compensate.

did that happen?

Presume compensate assumption has some inherent problems as described below:

App1 sends a DO message to App2. Coordinator (App1 site) decides to forget (presume compensate since no vote has been recorded). The participant (App2 site) times out and takes the presume-compensate route. But it hits a snag, and sends Fail. Coordinator receives Fail, but does not remember the activity anymore; so it does not propagate the Fail to its superior. This is a problem.

Summary: I suggest that we retain the existing presume nothing assumption as represented by the current state table transitions. Further, I suggest reversing the resolution to issue 71 so that we revert to the text: "All state transitions are reliably recorded, including application state and coordination metadata".

Proposed Resolution:

After line 73 insert:

 *   In the absence of outcome information for a transaction the transaction is presumed to have compensated.

State Table change:

The state table (line 520) ParticipantCompletion/Coordinator View/Inbound Events/:

{Completed, Ended} cell should be: (Send Compensate, Ended)

 The state table (line 530) CoordinatorCompletion/Coordinator View/Inbound Events/:

{Completed, Ended} cell should be: (Send Compensate, Ended)
