1972017-08-20T21:33:24  <BlueMatt> luke-jr: does it make sense to support non-segwit miners in 0.16? why not just remove some code instead?
1982017-08-20T21:33:57  <luke-jr> BlueMatt: I don't think we should force miners to support Segwit. Wait until they all do so by choice IMO.
1992017-08-20T21:34:00  *** promag has joined #bitcoin-core-dev
2002017-08-20T21:34:10  <luke-jr> BlueMatt: also, bugfixes should go into 0.15 too
2012017-08-20T21:34:19  <luke-jr> (even if the related code is removed in 0.16)
2022017-08-20T21:34:44  <BlueMatt> 10595 is not gonna make 15, its wayyyy too late (and is not a regression, even if you call it a bugfix)
2032017-08-20T21:35:06  <luke-jr> it's 2 months old now :p
2042017-08-20T21:35:07  <BlueMatt> I mean I dont disagree, but they could just as easily run pre-0.13.1 with 0.14/15 proxies
2052017-08-20T21:35:17  <promag> luke-jr: move comment https://github.com/bitcoin/bitcoin/pull/11026#issuecomment-322063440 to PR description?
2062017-08-20T21:35:18  <BlueMatt> ok, well I apologize I missed it until now
2072017-08-20T21:35:25  <luke-jr> BlueMatt: it has no practical effect, so 0.15.1 is fine
2082017-08-20T21:35:47  <BlueMatt> well my point is segwit is gonna activate by then, so we can see if its even needed at that point :p
2092017-08-20T21:35:49  <luke-jr> promag: k
2102017-08-20T21:36:07  <luke-jr> BlueMatt: 0.15.1 shouldn't remove features
2112017-08-20T21:36:34  <gmaxwell> sensible 0.15.1 thing.
2122017-08-20T21:36:55  <luke-jr> BlueMatt: note that #10595 isn't about Segwit active or not, but about whether the GBT client supports it
2132017-08-20T21:37:03  <BlueMatt> I'm aware, yes
2142017-08-20T21:37:13  <gmaxwell> luke-jr: I think matt's point is that it won't matter much if thats supported if it's virtually unused.
2152017-08-20T21:37:31  <luke-jr> it doesn't matter much either way
2162017-08-20T21:37:31  <BlueMatt> well other question, do any gbt clients actually care about those fields?
2172017-08-20T21:37:39  <luke-jr> just would be nice to get fixed so long as we support it
2182017-08-20T21:37:43  <BlueMatt> it was my impression they ignored them entirely and just used the txn selected by bitcoind
2192017-08-20T21:37:51  <luke-jr> BlueMatt: no, that's why it doesn't matter much
2202017-08-20T21:38:00  <BlueMatt> yea, ok
2212017-08-20T21:38:14  <luke-jr> there might be some edge cases for p2pool or Eligius since they make large generation txns
2222017-08-20T21:38:30  <luke-jr> but hopefully they'll just upgrade to Segwit if they haven't yet
2232017-08-20T21:38:57  <luke-jr> (and until then, a workaround is to set maxblocksize lower)

2252017-08-20T21:39:24  <gmaxwell> on that subject can we please stop setting irrational defaults for the maximum size.
2262017-08-20T21:39:46  *** cheese_ has quit IRC
2272017-08-20T21:39:52  <BlueMatt> what default do we have for max size?
2282017-08-20T21:40:07  <luke-jr> so reduce it?
2292017-08-20T21:40:08  <gmaxwell> we default to a maximum weight of 3million.
2302017-08-20T21:40:09  <BlueMatt> is it not just max_block_weight - sensible overhead of generation tx?
2312017-08-20T21:40:13  <BlueMatt> wtf whyyyyy
2322017-08-20T21:40:18  <BlueMatt> yea, lets fix that, please
2332017-08-20T21:40:19  <gmaxwell> because luke-jr
2342017-08-20T21:40:34  <luke-jr> because 1 MB blocks are not safe
2352017-08-20T21:40:39  <gmaxwell> -makemelosemoneyplease=1
2362017-08-20T21:41:00  <luke-jr> if we're going to go this road, we should softfork the block size limit down.
2372017-08-20T21:41:09  <BlueMatt> luke-jr: irrespective if they're ideal for the network or not, they are locally non-optimal for miners/users, something we should (and historically have always tried to) try to avoid
2382017-08-20T21:41:26  <BlueMatt> luke-jr: ok, go find consensus for that change then we'll make it happen!
2392017-08-20T21:41:29  <gmaxwell> the only effect these settings have is showing the world that we're idiots who don't care about the software working in reasonable ways.
2402017-08-20T21:41:57  <gmaxwell> Personally opting to use a lower size just makes to lose money, unless you're controlling hashpower for other people, in which case it makes them lose money.
2412017-08-20T21:41:58  <luke-jr> BlueMatt: no, historically we have tried to do what is best for the network. changing that has been an unfortunate campaign of some devs.
2422017-08-20T21:42:34  *** pandabull has quit IRC
2432017-08-20T21:42:39  <gmaxwell> That  is much of the reason that "have an infinite max blocksize and hope people will set it sensibly" doesn't work.
2442017-08-20T21:42:56  <BlueMatt> luke-jr: er, no, weve done things that are good for the network at very small difference for miners/users, we do not do things which are significantly non-optimal to the point that ~every user just changes the default
2452017-08-20T21:43:15  <gmaxwell> luke-jr: having a consistenct size is best for the network, smaller sizes make fee estimation less reliable, and hardly improve anything.  Lower _limits_ are another matter.
2462017-08-20T21:43:31  <luke-jr> only if the fee estimation logic is broken

2502017-08-20T21:44:16  <bitcoinreminder> does anyone has a bitcoin-org email address? I created a impersonation-request on twitter for the fake https://twitter.com/BcoreProject account, but they told me that someone with a bitcoin-org email address has to create the request
2512017-08-20T21:44:18  <gmaxwell> occasional blocks with mysteriously lower size makes the network capacity less predictable.
2522017-08-20T21:44:34  <luke-jr> bitcoinreminder: bitcoin.org isn't even Bitcoin Core..
2532017-08-20T21:44:46  <gmaxwell> no use in educating twitter on that.
2542017-08-20T21:44:49  <bitcoinreminder> sorry, I meant bitcoin-core.org

2592017-08-20T21:45:15  <luke-jr> bitcoinreminder: or do you mean bitcoincore.org ? just copy/paste what you mean :/
2602017-08-20T21:45:15  <bitcoinreminder> no sorry, I was talking about bitcoin-core
2612017-08-20T21:45:25  <bitcoinreminder> :P
2622017-08-20T21:45:27  <gmaxwell> hm.
2632017-08-20T21:45:39  <gmaxwell> do we even have email working there.. BlueMatt
2642017-08-20T21:45:55  <BlueMatt> gmaxwell: dunno, i see that there is an mx record, and there are at least aliases to send to it
2652017-08-20T21:46:16  <luke-jr> I'd expect btcdrak to be the one to know
2662017-08-20T21:46:18  <bitcoinreminder> just want to tell you, feel free do keep it in mind or ignore it :D
2672017-08-20T21:46:39  <bitcoinreminder> its just sad to see so much fud/lies spread there
2682017-08-20T21:46:47  <BlueMatt> yea, I assume btcdrak can figure out how to make it send
2692017-08-20T21:46:56  <gmaxwell> bitcoinreminder: sounds super useful.  yea, we'll get btcdrak to handle it.

2822017-08-20T21:58:21  <BlueMatt> sipa: yes, taht
2832017-08-20T21:58:22  <BlueMatt> that
2842017-08-20T21:59:57  <gmaxwell> sipa: is it faster than anything
2852017-08-20T22:00:16  <sipa> gmaxwell: haven't benchmarked
2862017-08-20T22:00:54  <BlueMatt> sipa: it would also be kinda nice to use that during block deserialization to set the hashes of the txn, but that would be a nontrivial change to serialization code :/
2872017-08-20T22:01:23  <sipa> yes...
2882017-08-20T22:01:30  <BlueMatt> but, yea, I'd be super excited to see something that makes merkle root calculation any faster
2892017-08-20T22:01:36  <BlueMatt> its one of my bigger bottlenecks
2902017-08-20T22:01:38  <gmaxwell> BlueMatt: I really want changes that let us NOT hash the transactions, so we can use that for rescan...
