[qt] Move some WalletModel functions into CWallet #10295

    Motivation for moving these is to make supporting IPC simpler (#10102), so these lookups can be one-shot IPC requests, instead of back-and-forth interactions over the IPC channel.

    Also these functions are potentially useful outside of the bitcoin GUI (e.g. for RPCs).

  2. jonasschnelli commented at 10:28 pm on April 28, 2017: contributor

    Yes. They belong to CWallet rather then WalletModel. The coincontrol’s ListCoins function can potentially be useful for non GUI features. My only nit is if we should rename ListCoins to something more meaningful.

    Concept ACK.

    nit: might be nice to LOCK here.
    jonasschnelli commented at 6:18 pm on May 4, 2017:
    Not sure if a lock is required at this point. Do you want to protect const CCoinControl* coinControl? AvailableCoins() does protect via cs_main/cs_wallet.
    TheBlueMatt commented at 8:26 pm on May 4, 2017:
    We have pointers in the COutput to entires in mapWallet, which can (theoretically) be delted out from under us thanks to the zap rpc.

    Why did you change to false for safe here…looks like the old code did true? Does that have any effect?

    It has no effect (I’m not even exposing it to Qt any more after 7a7795fdd5fe86b9918b8055666b8365e4342eb6 in #10244) and false seemed like a more correct value.

    Looks good, seems reasonable, though I hope we can delete half the code here (see #10337).
