ticketbuyer.balancetomaintainabsolute not respected

The ticketbuyer.balancetomaintainabsolute setting does not seem to be respected.

My balance is routinely drawn down below this limit when purchasing tickets.

@jrick may i investigate and try fix this one ?

[jrick]

doesn't need much investigation because we understand why this happens -- as utxos are selected, the confirmed balance might dip below this configuration value, since the change will be unconfirmed.

I'm not sure if this is anything we need to fix. Talking about balances (as this config option does) without also talking about the number of confirmations is meaningless.

[chappjc]

In my experience (at the time) if you let the wallet run indefinitely, you will get to a point where there is no (or very little) unconfirmed, yet you've fully depleted your balance on tickets.

[amass01]

Aha, I see

[jrick]

@chappjc this is because the unconfirmed balance is going to a different account, e.g. unmixed. This option predates the mixing support and this use case.

[chappjc]

That's not my recollection. I suggest running testnet wallets with and without mixing, with a non zero balancetomaintainabsolute. I think in both case it's not just unconfirmed or unmixed change. Maybe I'm wrong and this can be closed, but the wallet would become way over bought into tickets, where either unconfirmed or unmixed account balances don't even come close to the requested setting.

[chappjc]

My testnet ticketbuyer is presently not mixing. Will set it and try now.

[jrick]

thanks. let's find out if the option works as i'm recalling, otherwise we should discuss how we'd prefer it to work. if it is "working" then at the very least we need to clarify what the option really does because as is the description is extremely vague.

Oh dang, ticketbuyer.limit is the wrong setting. Where did that come from? :angry:

[chappjc]

Ok, sorry for the noise, this was just a screw up on my part it seems. With --ticketbuyer.balancetomaintainabsolute=200 and no mixing it's working as expected.

There may be a warranted clarification when mixing is in use, but it seem PEBKAC.

   --ticketbuyer.balancetomaintainabsolute= Amount of funds to keep in wallet when purchasing tickets (default: 0 DCR)
