11:09 < laanwj> the boost::filesystem removal was merged today, i'd recommend testing the current master branch on as many platforms and operating systems as you can to make sure any issues come to light
11:09 < sipa> Good idea.
11:09 < warren> That was the last boost dependency?
11:09 < laanwj> i don't expect anything but you never know!
11:09 < michaelfolkson> Presumably #22558 shouldn't get 23.0 milestone? Not much review yet
11:09 <@gribble> https://github.com/bitcoin/bitcoin/issues/22558 | psbt: Taproot fields for PSBT by achow101 · Pull Request #22558 · bitcoin/bitcoin · GitHub
11:10 < michaelfolkson> Would be nice to get some Taproot stuff in 23.0 but obviously needs review
11:10 < laanwj> warren: there's still signals2, which is quite easy to replace, and boost::multi_index, which is not
11:10 < sipa> warren: We have lots of boost dependencies still, but most are headers-only
11:10 < sipa> or all?
11:10 < warren> Is it a goal to get rid of boost eventually?
11:10 < laanwj> sipa: afaik yes
11:10 < hebasto> all are headers only except for Boost.Test
11:10 < sipa> warren: I don't care about getting rid of headers-only ones.
11:11 < luke-jr> no
11:11 < sipa> They're just a build-time dependency.
11:11 < laanwj> ah yes, boost::test, didn't count that one as it's test only
11:11 < laanwj> right, there's no real hurry, though signals2 is kinda ugly due to the enormous backtraces it generates
11:11 < sipa> boost::multi_index in particular would be a major engineering challenge to replace with anything similar in functionality
11:12 < laanwj> yeah... might just import that one :)
11:12 < MarcoFalke> Someone should shepherd multi_index into C++26
11:12 < laanwj> in any case, it's fine, would be good if it was behind a pimpl though so it didn't get imported into every other file
11:13 < laanwj> MarcoFalke: yea!
11:13 < sipa> right
11:14 < laanwj> michaelfolkson: not sure really, if it makes 23.0 it makes 23.0, but i'm not sure it makes sense to specialy label it for that
11:14 < jonatack> could #24165 be tagged for v23?
11:14 <@gribble> https://github.com/bitcoin/bitcoin/issues/24165 | p2p: extend inbound eviction protection by network to CJDNS peers by jonatack · Pull Request #24165 · bitcoin/bitcoin · GitHub
11:15 < jonatack> vasild and i are coordinating to propose a doc/cjdns.md for v23 as well
11:15 < sipa> cool
11:15 < laanwj> if it's unlikely to make it, it shouldn't be added to the milestone, generally nothing but critical fixes actually blocks a release anyway
11:15 < laanwj> jonatack: will do
11:15 < jonatack> thanks!
11:16 < laanwj> jonatack: concept ACK, though, should keep it compact imo, i don't think we should end up with extensive documentation about setting up all kind of overlay network in our repo
11:17 < laanwj> granted, tor.md is pretty big but that's mainly because we have a lot of configurability related to tor
11:18 < jonatack> laanwj: yes. the main thing people seem to trip up on when getting started is the find a friend part (myself included).
11:18 < laanwj> jonatack: yes, that's always the difficult part :)
11:19 < Murch> #proposedmeetingtopic sweep vs subtract-fee-from-output
11:19 < laanwj> i hope cjdns.md will help some people find friends :p

11:19 < sipa> Murch: For this meeting, or wallet meeting?
11:20 < michaelfolkson> Has to wait a week if it is wallet meeting :)
11:20 < Murch> Pieter: If this meeting runs out of topics, I'd be happy to talk about it here, but otherwise wallet meeting is fine, too.
11:21 < laanwj> we're out of topic right now, so, happy to take it
11:21 < Murch> Okay
11:21 < laanwj> #topic sweep vs subtract-fee-from-output (Murch)
11:21 < core-meetingbot`> topic: sweep vs subtract-fee-from-output (Murch)
11:21 < warren> summary writeup of this anywhere?
11:21 < Murch> achow101 and I have been looking into implementing a Sweep RPC in https://github.com/bitcoin/bitcoin/pull/24118
11:22 < Murch> The main motivation is that SFFO creates a bunch of issues for coin selection and makes testing more complex
11:23 < Murch> Our impression was that the main use case for SFFO was to perform sweeps and to spend the full balance of wallet
11:23 < Murch> This was at least the cited reasons in #4331 when it was proposed.
11:23 <@gribble> https://github.com/bitcoin/bitcoin/issues/4331 | Subtract fee from amount by cozz · Pull Request #4331 · bitcoin/bitcoin · GitHub
11:23 < laanwj> it's useful for sending entire utxos to another wallet
11:24 < Murch> laanwj: We intend for sweep to also allow specifying input UTXOs
11:24 < Murch> It's not in the current iteration, but something we want to do in a follow-up
11:24 < laanwj> i've used it pretty often and never for sweeps
11:24 < jeremyrubin> very much supportive of sweep and getting rid of SFFO; generally speaking if i am trying to pay someone 10000 sats and they get 9999, that might not be a valid payment anymore. SFFO seems like a huge footgun.
11:24 < laanwj> the target might not be a bitcoin core wallet (e.g. c-lightning, joinmarket, etc)
11:25 < provoostenator> We could call it "sendcoins" instead of sweep, but potato potato
11:25 < warren> I've used SFFO often to selectively combine only specific UTXO's where I don't want change outputs. It seems strange if that's taken away.
11:25 < laanwj> it's not useful for sending to other people, agree
11:25 < Murch> laanwj: Could you describe the use case that leads to an SFFO payment?
11:25 < Murch> We've been trying to figure out what people use it for.
11:25 < laanwj> Murch: coinjoin, sending an entire utxo without generating an extra change input
11:25 < laanwj> or combining a bunch of utxos
11:26 < provoostenator> Murch: sending 1 UTXO to an exchange
11:26 < laanwj> it's good for privacy generally to not generate change
11:26 < Murch> laanwj: So if you could specify a set of UTXOs in sweep, that seems to be covered
11:26 < laanwj> especially if your utxos are already not linked
11:26 < provoostenator> And to not combine coins from different source
11:26 < laanwj> right
11:26 < jeremyrubin> laanwj: altho not generating change is also a privacy leak itself
11:27 < laanwj> jeremyrubin: it's kind of subtle
11:27 < Murch> jeremyrubin: Not when you have multiple recipients. ;)
11:27 < laanwj> Murch: can you sweep to another address or set of addresses?
11:27 < jeremyrubin> laanwj: if you're one of the only people in the world with this pattern rn, i may be able to find you ;)
11:28 < sipa> using SFFO to construct the spending of specific UTXOs without change is kind of a roundabout way of doing it... it's essentially trying to trick the coin selection into doing what you want, rather that just not doing coin selection at all
11:28 < provoostenator> jeremyrubin: that's what on chain dobbelgangers are for, I'm sure you can hire those.
11:28 < Murch> laanwj: Yes, the rpc takes multiple addresses of which at least one must not specify an amount and gets the remainder. If multiple are unspecified, it splits equally.
11:28 < laanwj> jeremyrubin: sigh, sure, we can't really talk about use-cases here and this whole discussion is moot
11:28 -!- prayank [~Prayank@45.64.9.48] has joined #bitcoin-core-dev
11:29 < warren> Several users I recruited over the years use SFFO with multiple outputs to obscure which output is payment further making the amounts sent not round numbers. But I've personally used it to avoid creating change outputs when sending to myself or to other people were exact amounts don't matter or they're willing to eat the tx fee as part of the bargain.
11:29 < jeremyrubin> laanwj: didn't mean to badger you, just a reminder that 'good for privacy' depends on the behavior being widespread generating anonymity set.
11:29 < Murch> Another use case we've gotten feedback about on Twitter was that you "can make the receiver pay the fees". This seems like a roundabout way of making the receiver take a risk on how large a transaction is going to be, and would imho be better implemented by deducting a flat amount.
11:30 < provoostenator> I don't have strong feelings about what it should look like under the hood.  But the current manual coin selection GUI works fine for it.
11:30 < prayank> This was the thread: https://nitter.net/achow101/status/1488624425285079048
11:30 < laanwj> in any case, i do like the sffo functionality, and would be sad to see it go
11:30 < laanwj> roundabout way or not
11:30 < provoostenator> Murch: or just setting the fee to 1 sat/byte?
11:30 < Murch> Mh, okay, noted.
11:30 < laanwj> i'm fine if it only works with manual coin control
11:31 < _aj_> maybe don't deprecate until the "specifying input UTXOs" part is done?
11:31 < warren> +1 provoostenator I like the current coin control GUI and option for SFFO I use almost always. How it works under the hood is a different matter.
11:31 < Murch> provoostenator: I'm not sure I follow
11:31 < laanwj> and skips coin selection
11:31 < sipa> _aj_: I'd assume that'd be the case
11:31 < jonatack> if SFFO includes the subtractfeefromamount option in RPCs like sendtoaddress, i find it useful when someone wants to buy btc, sets the feerate, and pays the fee
11:31 < provoostenator> Murch: if the recipient wants to CPFP you can just use a low fee rate
11:31 < laanwj> warren: right-i suspect it's pretty much  always used with manual coin control
11:31 < jeremyrubin> laanwj: what about just being able to generate a transaction automatically and then modify it to deduct the fees manually from the outputs you want to deduct?
11:31 < Murch> provoostenator: That requires sending a second transaction, though.
11:32 < _aj_> #24142
11:32 <@gribble> https://github.com/bitcoin/bitcoin/issues/24142 | Deprecate SubtractFeeFromOutputs by achow101 · Pull Request #24142 · bitcoin/bitcoin · GitHub
11:32 < laanwj> jeremyrubin: i like it's user friendly and easy to use now
11:32 < provoostenator> Indeed  limiting it to manual coin selection would be fine by me too
11:32 < provoostenator> So basically if you select any coins, we don't auto select more.
11:32 < warren> +1
11:32 < achow101> apparently bull bitcoin (an exchange) uses sffo to make their users pay the fee if they want to opt out of batched transactions. limiting to manual would break that use case
11:32 < laanwj> sure, i know how to make manual transactions and subtract fee etc, but having to compute things manually sucks compared to just using the interface
11:33 < cfields> +1
11:33 < jonatack> +1
11:33 < provoostenator> achow101: Murch: oh now it makes sense
11:33 < jeremyrubin> i think subtracting fees could be done in a user friendly 
11:33 < cfields> jeremyrubin: Indeed I've done that several times.
11:33 < jeremyrubin> like 10 - x works in e.g. GIMP
11:33 < jeremyrubin> (for computing pixels or whatever)
11:33 < provoostenator> So they're "paying" by just lowering the amount they receive?
11:34 < laanwj> it's clearly controversial to remove this functionality
11:35 < achow101> indeed
11:35 < laanwj> not arguing against adding a sweep RPC, but i think proposing it to replace sffo is getting ahead of things
11:35 < warren> +1
11:35 < Murch> Right, thanks for the feedback!
11:35 < achow101> i guess we need to unbreak sffo first

11:43 < Murch> That's what we propose for sweep.
11:46 < Murch> FWICT, there just remains one case that we cannot cover which is sending to a recipient using the amount owed to them as the budget.
11:47 < jeremyrubin> Murch: would it help if you had a min / max for a recipient?
