`listsinceblock` did not behave correctly when handed a block that was
|
|
no longer in the main chain:
|
|
|
|
ab0
|
|
/ \
|
|
aa1 [tx0] bb1
|
|

|
|
aa2 bb2
|
|
| |
|
|
aa3 bb3
|
|
|
|
|
bb4
|
|
|
|
Consider a client that has only seen block `aa3` above. It asks the node
|
|
to `listsinceblock aa3`. But at some point prior the main chain switched
|
|
to the bb chain.
|
|
|
|
Previously: listsinceblock would find height=4 for block aa3 and compare
|
|
this to height=5 for the tip of the chain (bb4). It would then return
|
|
results restricted to bb3-bb4.
|
|
|
|
Now: listsinceblock finds the fork at ab0 and returns results in the
|
|
range bb1-bb4.
|
|
|
|
This test only checks that [tx0] is present.

Problematic case:
|
|
|
|
1. User 1 receives BTC in tx1 from utxo1 in block aa1.
|
|
2. User 2 receives BTC in tx2 from utxo1 (same) in block bb1
|
|
3. User 1 sees 2 confirmations at block aa3.
|
|
4. Reorg into bb chain.
|
|
5. User 1 asks `listsinceblock aa3` and does not see that tx1 is now
|
|
invalidated.
|
|
|
|
Currently the solution to this is to detect that a reorg'd block is
|
|
asked for in listsinceblock, and to iterate back over existing blocks up
|
|
until the fork point, and to include all transactions that relate to the
|
|
node wallet.
