Extend CMerkleTx::GetDepthInMainChain with the concept of a "conflicted" transaction-- a transaction generated by the wallet that is not in the main chain or in the mempool, and, therefore, will likely never be confirmed. GetDepthInMainChain() now returns -1 for conflicted transactions (0 for unconfirmed-but-in-the-mempool, and >1 for confirmed). This makes getbalance, getbalance '*', and listunspent all agree when there are mutated transactions in the wallet. Before: listunspent: one 49BTC output getbalance: 96 BTC (change counted twice) getbalance '*': 46 BTC (spends counted twice) After: all agree, 49 BTC available to spend.pull/145/head
