  42017-08-29T00:15:19  <tloriato> Hello. Good morning/night. I was wondering where I could find a Javascript documentation on how to interact with a Bitcoin full node via JSON RPC? Sorry if I'm in the wrong place, I'm new to the space and trying to develop some things

 152017-08-29T01:58:34  <kallewoof> After a day of stats, I have some updates regarding the mempool optimization for fees. Still WIP but looks interesting so far. Blocks 482344 ~ 482418:
 162017-08-29T01:58:36  <kallewoof> [bench::fees (    conservative|non-mempool)] 11940 ests, 11940 overshoots (313659 more sat/k/tx), 0 undershoots (0 less sat/k/tx)
 172017-08-29T01:58:38  <kallewoof> [bench::fees (non-conservative|non-mempool)] 12198 ests, 11940 overshoots (187298 more sat/k/tx), 258 undershoots (14414 less sat/k/tx)
 182017-08-29T01:58:40  <kallewoof> [bench::fees (    conservative|    mempool)] 12745 ests, 11913 overshoots (85940 more sat/k/tx), 820 undershoots (23188 less sat/k/tx)
 192017-08-29T01:58:42  <kallewoof> [bench::fees (non-conservative|    mempool)] 13102 ests, 11879 overshoots (56938 more sat/k/tx), 1216 undershoots (23577 less sat/k/tx)
 202017-08-29T01:58:44  <kallewoof> For mempool use, 6.5% undershot (conservative) / 9.3% undershot (non-conservative) (<-- still needs work)
 212017-08-29T01:58:46  <kallewoof> On average 227719 sat/k (72.6%) was saved for conservative / 130360 sat/k (30.4%) for non-conservative.

 772017-08-29T08:19:21  <luke-jr> I agree nobody probably really cares about building without libevent tho :p
 782017-08-29T08:19:39  <luke-jr> even the person asking me to make it available in Core, didn't want to uninstall libevent to test a patch

 842017-08-29T08:37:28  <wumpus> btw thanks fanquake achow101 meshcollider for being so quick to do gitian builds (and cfields for uploading the sigs quickly), we're getting really fast at doing rcs/releases :)
 852017-08-29T08:39:05  <luke-jr> does that mean we should up the sig requirement to 5 signers? :p
 862017-08-29T08:39:50  <wumpus> would make sense to do that for final releases

 942017-08-29T08:41:36  <luke-jr> that sounds easy enough
 952017-08-29T08:41:47  <luke-jr> I'm more curious how much trouble it will be to do gitian on Talos
 962017-08-29T08:41:55  <wumpus> easier than on gentoo?
 972017-08-29T08:42:09  <luke-jr> dunno, depends on Fedora having dependencies
 982017-08-29T08:42:21  <MarcoFalke> It shouldn't be a problem. I am still waiting on the package, though.
 992017-08-29T08:42:31  <luke-jr> particularly vmbuilder
1002017-08-29T08:42:39  <luke-jr> which afaict is Ubuntu home-grown
1012017-08-29T08:42:51  <wumpus> so are Talos' actually for sale already?

1052017-08-29T08:43:39  <wumpus> vmbuilder should be reasonably easy to build from source IIRC
1062017-08-29T08:43:43  <luke-jr> upgraded since the Talos "1" that never happened

1112017-08-29T08:50:53  <wumpus> bleh, if not, I wouldn't really feel comfortable owning it in the first place, will be impossible to get either hardware or software support for a one-off product

2242017-08-29T17:12:30  <sdaftuar> kanzure: i don't think stale blocks would trigger that in general -- just disk corruption or pruning i think.
2252017-08-29T17:12:30  <jnewbery> instagibbs: bitcoind wallet doesn't allow fees to be bumped for transaction that have descendants in the wallet or mempool, so in practice I don't think it's much of an issue. sdaftuar would be the man to ask
2262017-08-29T17:12:58  <kanzure> sdaftuar: if no pruning enabled then it would have to be disk corruption ya?
2272017-08-29T17:13:35  <sdaftuar> kanzure: i think so.  only other case i can think of is if you upgraded a pre-segwit node after segwit activated, triggering the rewindblockindex code.  i assume that's not something you did?
2282017-08-29T17:13:55  <kanzure> testnet node in this case
2292017-08-29T17:14:01  <kanzure> no recent upgrade
2302017-08-29T17:15:16  <sdaftuar> then yeah disk corruption sounds like the culprit
2312017-08-29T17:15:44  <kanzure> is it terribly unhealthy to do fast bitcoind kills in succession and will that cause disk corruption
2322017-08-29T17:17:35  <sipa> what kind of hardware?

2362017-08-29T17:21:03  <sdaftuar> kanzure: restore from your last backup?
2372017-08-29T17:21:06  <sipa> sorry, the block files are needed to even rewind the utxo set
2382017-08-29T17:22:17  <kanzure> other than restore, what is the hard way?

2552017-08-29T17:32:53  <sdaftuar> and maybe we could loosen the requirement that all the new inputs already be confirmed

2652017-08-29T17:59:16  <gmaxwell> Can someone who understands twitter better explain to me what blocking someone does there... what would blocking someone on the bitcoin core account accomplish?
2662017-08-29T18:02:18  <instagibbs> it's an annoying feature tbh, all it does is stop a logged in account that is blocked from seeing messages and/or pinging notifications
2672017-08-29T18:02:35  <instagibbs> which is easily routed by just loading twitter not logged in...
2682017-08-29T18:03:28  <gmaxwell> Then why would any role account (like bitcoincoreorg) ever block anyone?  Seems like all it would do is create offense for no gain.
2692017-08-29T18:03:55  <instagibbs> Perhaps to sift through mentions easier, although muting does this, and doesn't offend
2702017-08-29T18:04:38  <instagibbs> muting is just so you don't "hear" about that person talking about your account, or see their tweets when people RT them
2712017-08-29T18:06:28  <instagibbs> I think a policy of "only muting" is totally appropriate, regardless of motivations
2722017-08-29T18:08:13  <gmaxwell> I suppose it may have the effect of lowering the incidence of crap posting your announcements, but just causing them to not see them more often.
2732017-08-29T18:08:16  <gmaxwell> But otherwise it seems completely useless.

2782017-08-29T18:18:48  <jnewbery> I *think* blocking would also prevent the blocked party from replying to your tweets, so other people won't see their crap. So I think it is appropriate to block pure trolls/impersonators.
2792017-08-29T18:19:12  <gmaxwell> If it blocks replies then is serves a real purpose.
2802017-08-29T18:19:20  <gmaxwell> So, lets assume for a moment that we do that.
2812017-08-29T18:20:28  <gmaxwell> We put announcements of new releases out on twitter,  if there is an account that constatly replies the the announcements with offtopic fudding than then diverts the replies into noise arguing with the... I think blocking them would be appropriate.
2822017-08-29T18:20:46  <gmaxwell> (arguing with them)
2832017-08-29T18:21:14  <gmaxwell> People doing that, incidentally, was one of the reasons I wasn't super excited about the project having a twitter account to begin with.
2842017-08-29T18:21:41  <luke-jr> yes, Twitter blocks prevent replies, which is why I actually block people on it (typically I don't)

3642017-08-29T21:38:55  <esotericnonsense> not sure if this is offtopic for the channel. is there a discussion anywhere surrounding why bitcoin uses bdb 4.8? it seems to me that the only real concern with using 5.x is that users would not then be able to downgrade wallet software, but how likely/useful is that anyway (and also, providing recompiled binaries for older releases with 5.x seems possible now?)

3962017-08-29T23:42:20  <achow101> can someone help me figure out what is wrong with https://github.com/achow101/bitcoin/tree/split-signraw-broken? That's my in progress rebase and comment addressing of #10579
3972017-08-29T23:42:29  <achow101> I'm having some assertlockheld problem

4012017-08-29T23:49:39  <achow101> no, it fails tests with an assertion error about assertlockheld failing
4022017-08-29T23:49:53  <achow101> maybe I should try it normally first
4032017-08-29T23:50:39  <achow101> actually nvm. I didn't make clean so an earlier broken version was the problem
