    #12953 inadvertently removed the functionality to call getbalance "*" <int> <bool> to get the wallet’s balance with either minconfs or include_watchonly.

    This restores that functionality (when -deprecatedrpc=accounts), and also makes it possible to call ``getbalance minconf= include_watchonly=` when accounts are not being used.

    Feedback to address from @ryanofsky

    Some thoughts looking at code:

    • It seems like it would be good to raise an error if IsDeprecatedRPCEnabled("accounts") and the account argument is not null or “*”. Otherwise the argument would be silently ignored.
    • Documentation seems to say default minconf is 1, while implementation uses 0 or 1.
    • Maybe could dedup caching code in GetAvailableCredit a little with something like
    0CAmount* cache = filter == ISMINE_SPENDABLE  ? nAvailableCreditCached : 
    1                 filter == ISMINE_WATCH_ONLY ? nAvailableWatchCreditCached :
    2                 nullptr;

    I guess that would not work for min dept of 0 (unconfirmed).

    Are you saying that we also need to check pcoin->InMempool() for coins with 0 depth?

  5. [wallet] GetBalance can take an isminefilter filter.
    GetBalance() can now take an ismine filter, which is passed down to
    GetAvailableCredit. This allows GetBalance to be used to get watch-only
    balances.

    I believe that I’ve addressed all of @ryanofsky’s feedback. Russ - can you rereview and confirm?

    Need to address @jonasschnelli’s comment. Jonas - can you please confirm my question above? Thanks!

    ryanofsky commented at 1:39 pm on June 29, 2018:

    In commit “[RPC] [wallet] allow getbalance to use min_conf and watch_only”

    I think the safest thing here would be to raise an error whenever accounts are deprecated and account is non-null, because previously getbalance(null), getbalance("*"), and getbalance("") each did different things, and it doesn’t seem good to silently ignore a requested behavior. Another slightly less safe but maybe acceptable option would be to change "" to "*" on this line, since getbalance("*") and getbalance(null) at least were more similar than getbalance("*") and getbalance("")

    Previously, and currently with the deprecated accounts feature enabled:

    • getbalance(null) would return total balance
    • getbalance("*") would return total balance with legacy accounting method
    • getbalance("account") would return balance associated with a named account
    • getbalance("") would return leftover balance not associated with any named accounts

    ryanofsky commented at 2:23 pm on June 29, 2018:

    #13566 (review)

    Also want to note that another approach we could take here would not be to deprecate the account argument at all, but instead just rename it to label and pass it down as an option to the GetBalance() and GetAvailableCredit methods where it could be used to filter txouts there by address label. This would be a simple code change, just adding if (!label || *label == GetLabelName(txout.scriptPubKey)).

    utACK c57f2009f65ffedc7531644243d5d7ddd786edde if getbalance("") is not treated like getbalance(null), (see comment).

    It looks like we might have had tests for this previously which were deleted. It could be better in the future to avoid dropping tests for deprecated features until the features are actually removed, though it is sometimes nice to simplify tests.

    Thanks @ryanofsky . Updated to treat * as an acceptable dummy argument.

    I don’t think we want to entirely remove the possibility of calling this method with positional arguments.

    utACK 43937db46edab8c226ce190e185d7a3285b3b364, only change since last review is requiring “*” instead of "" to signify all accounts. Thanks for implementing this and all the changes.

    What if filter == ISMINE_ALL — which can be when include_watchonly=true in RPC getbalance — could sum both if cached?

    jnewbery commented at 3:54 pm on November 1, 2018:
    No, cache and cache_used are updated below even if fUseCache is not set.

    Seems like a reasonable optimization, but I don’t think it’s required. Could be done in a separate PR.
