`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. |
