Robbie Gemmell updated DISPATCH-1488:
-------------------------------------
Description:
The 1.9.0 release and current master for 1.10.0 both truncate the 'declared'
transaction delivery state when routing a transaction coordinator link to a
broker peer, omitting the contained txn-id and breaking all ability to link
route transactional work through the router.
Some output while trying this to debug an unrelated issue is detailed below.
First, a message transfer arrives at the router with body requesting a
transaction declare. The router sends the link-routed transfer onward to the
broker:
{noformat}
[0x2251560]:1 <- @transfer(20) [handle=0, delivery-id=0, delivery-tag=b"\x00",
message-format=0, settled=false] (7) "\x00Sw\x00S1E"
[0x21ddf40]:0 -> @transfer(20) [handle=1, delivery-id=0, delivery-tag=b"\x00",
message-format=0] (7) "\x00Sw\x00S1E"
{noformat}
(Not shown, after the above in the case being debugged, there was a
non-transactional transfer on a second session across the same client->router
connection, then forwarded on the same router->broker connection).
The broker peer establishes a transaction and responds with disposition to
indicate it is declared, and providing the mandatory txn-id. The router relays
this disposition, but critically drops the txn-id from the delivery state:
{noformat}
[0x21ddf40]:0 <- @disposition(21) [role=true, first=0, last=0, settled=true,
state=@declared(51) [txn-id=b"4a12a39a-09fe-11ea-91ae-000c29e9f622"]]
[0x2251560]:1 -> @disposition(21) [role=true, first=0, settled=true,
state=@declared(51) null]
{noformat}
The recipient client then barfs at this point since txn-id is mandatory for the
declared state.
Using 1.8.0, the declared state transited the router fine:
{noformat}
[0x1f49530]:0 <- @disposition(21) [role=true, first=0, last=0, settled=true,
state=@declared(51) [txn-id=b"78dabc4f-0a00-11ea-bb46-000c29e9f622"]]
[0x1fc2b20]:2 -> @disposition(21) [role=true, first=0, settled=true,
state=@declared(51) [txn-id=b"78dabc4f-0a00-11ea-bb46-000c29e9f622"]]
