5d536619ab [tests] Remove 'account' API from wallet functional tests (John Newbery) Pull request description: Next step in #12952. Removes all usage of the 'account' API from the wallet functional tests, except: - rpc_deprecated.py (which specifically tests the `-deprecatedrpc=accounts` command line argument is working properly). - `wallet_labels.py` (which tests that both the 'label' and 'account' APIs work in V0.17). 'account' API usage for both of those tests can be removed once V0.17 has been branched. Also excluded is: - `wallet_importprunedfunds.py` (which fails due to a bitcoind OOM error) Tree-SHA512: 6701b32f83d2d47597ba093ded665d7aa630f7a9c759ff15e3e33a3e3bc7600e8d29cf4e72aed5f8f9f6769cc9b614c681951720eab1ed2473f5f8dec57e7a6f

`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.
