382018-09-18T02:14:23 <bralyclow> is v0.16.3 official release yet?
392018-09-18T02:15:37 <bralyclow> I see listed as unofficial release, but it is not tagged Latest Release yet
402018-09-18T02:20:35 <fanquake> bralyclow It was only tagged a few hours ago, gitian builds still need to be done
412018-09-18T02:20:41 <gmaxwell> bralyclow: it's been tagged but the binaries are not up yet, since it takes time for the determinstic build process do to its thing.
422018-09-18T02:21:05 <fanquake> (which are under way at the moment)
432018-09-18T02:21:47 <bralyclow> very good, thank you for update/clarify, will wait on binaries for mac
442018-09-18T02:22:19 <bralyclow> btw, when might 0.17 be released as I see at rc4 now?
452018-09-18T02:25:26 <achow101> bralyclow: 0.17 will be released when we stop finding bugs in it for a week or 2

862018-09-18T07:37:05 <zndtoshi> Pierre Rochard explained in a presentation about Bitcoin Governance that consensus is reached similary to people meeting at the Schelling point: they know the city but not the location and hour to meet. They will think what the other would do and vice versa and in NY meet in Grand Central Station at noon without communicating. So conseus in Bitcoin is the same: everyone gravitates to the right software to use or the rig
872018-09-18T07:37:15 <zndtoshi> miners. They have a veto option by signaling acceptance or not of a future softfork. But they should/will meet with everyone else at the Schelling point as well. Is there a REAL need for mining nodes to signal inside the Bitcoin Network? If not, are there any risks to remove mining node signaling?

1562018-09-18T12:52:04 <wumpus> fanquake: yes, probably would make sense to tag a 0.15.x release as well
1572018-09-18T12:52:54 <wumpus> though that is less urgent, today I'd ideally like ot upload binaries for 0.17.0rc4 and 0.16.3 at least
1582018-09-18T12:55:32 <achow101> 0.14 isn't EOL yet too
1592018-09-18T12:57:36 <wumpus> the patch has been backported to both 0.14 and 0.15
1602018-09-18T13:00:06 <wumpus> making a release on those branches is pretty much only a matter of writing (short) release notes, if anyone wants to speed it up and have a go at those, be my guest
1612018-09-18T13:04:51 <fanquake> wumpus np. I've just merged achow's sigs. So we've got 3 builders for 0.16.3 and 4 for 0.17.0rc4 so far.

2162018-09-18T17:10:47 <leishman> I find the bitcoin-core-dev irc logs on botbot super useful for following development progress and learning. Are there channel logs anywhere else?

2202018-09-18T17:12:29 <leishman> oh haha. I may try to run a version of the botbot logger since it's open source and has a much better UI than the others
2212018-09-18T17:13:36 <echeveria> it however, does seem to have a crazy amount of deps.

2232018-09-18T17:15:05 <echeveria> I guess not too many, I thought foreman was ruby (along with go, python).
2242018-09-18T17:17:47 <leishman> yeah. shouldn't be too difficult to write a simple logger and put a UI on top of it either.

2952018-09-18T20:57:14 <ossifrage_> gmaxwell, I was just building a fresh bitcoin and noticed I still had a madvise(MADV_RANDOM) when mmapping read only data in leveldb, Is this worth a PR? It seem to reduces the number of pages fetched, but I don't have a good way to show if it actually helps

3042018-09-18T21:00:44 <ossifrage> wumpus, it does reduce the working set of pages pulled (at least initially) if people actually care about that (I don't)
3052018-09-18T21:01:06 <wumpus> ossifrage: I care about it if it helps performance!
3062018-09-18T21:01:47 <luke-jr> might be more of a system performance thing than bitcoind performance
3072018-09-18T21:01:59 <luke-jr> (which IMO is still worth getting it merged upstream)
3082018-09-18T21:02:48 <ossifrage> luke-jr, yeah it is a system level issue, which makes it much harder to test
3092018-09-18T21:03:23 <luke-jr> run Chromium on the test system :P
3102018-09-18T21:03:26 <luke-jr> on btrfs
3112018-09-18T21:03:28 <luke-jr> lol
3122018-09-18T21:03:49 <ossifrage> It depends heavily on how much system level memory pressure you have and how fast your IO is
3132018-09-18T21:06:43 <ossifrage> luke-jr, g++ seems triggers way more violent page eviction then chrome does. chrome is a slow burn, g++ is a punch in the face

3182018-09-18T21:13:05 <provoostenator> Is there a way to curse blocks, i.e. the opposite of "preciousblock"?
3192018-09-18T21:13:57 <sipa> invalidateblock
3202018-09-18T21:14:02 <provoostenator> Thanks
3212018-09-18T21:14:21 <sipa> (which is more than cursing, it marks the block as unconditionally invalid)
3222018-09-18T21:14:28 <sipa> the oppposite of invalidateblock is reconsiderblock
3232018-09-18T21:14:52 <midnightmagic> and of course there's the ancillary haveteawithblock
3242018-09-18T21:15:23 <jamesob> any idea when bitcoincore.org is going to be updated with 0.16.3's release notes?

3322018-09-18T21:20:25 <wumpus> theymos: some miners have already upgraded, don't know the % though
3332018-09-18T21:21:12 <theymos> Do you think that I mention in my bitcointalk.org announcement that a chain split is possible?

3362018-09-18T21:23:41 <achow101> theymos: a chain split is not possible
3372018-09-18T21:23:42 <provoostenator> An invalid block could crash a node, but no node, patched or unpatched would accept such a block
3382018-09-18T21:23:57 <theymos> ok, thanks
3392018-09-18T21:24:36 <achow101> however, if you remove the assert that causes the crash, then you would accept an invalid block. but no release has that
3402018-09-18T21:28:58 <wumpus> bitcoincore.org and bitcoin.org PRs have both been merged, should be a matter of times before the sites update...
3412018-09-18T21:30:08 <gmaxwell> ossifrage: I should benchmark a reindex I guess.

3502018-09-18T22:09:51 <wumpus> ok
3512018-09-18T22:15:22 <TD-Linux> gmaxwell, are there "standard" reindex benchmark settings?
3522018-09-18T22:16:28 <gmaxwell> TD-Linux: defaults, and dbcache=10000 (e.g. big enough that it never flushes) are the two cases that are most interesting. It's useful to -connect=0 to stay offline while benchmarking.

3722018-09-18T22:50:00 <TD-Linux> indeed boost's cpuinfo parsing won't work on my /proc/cpuinfo
3732018-09-18T22:50:40 <TD-Linux> it looks for the number of unique (physical id, core id) pairs but that is not a unique identifier on my machine
3742018-09-18T22:51:47 <luke-jr> I don't even have physical/core ids in mine XD
3752018-09-18T22:53:32 <TD-Linux> yeah so I'm running master for my benchmark
3762018-09-18T22:53:41 <TD-Linux> boost would actually say I only have 8 cores with its logic
3772018-09-18T22:54:06 <TD-Linux> I'll file a boost bug but I guess I also need a libstdc++ bug
3782018-09-18T22:54:06 <luke-jr> >_<
3792018-09-18T22:55:14 <luke-jr> does get_nprocs() work?
3802018-09-18T22:55:56 <luke-jr> I guess that doesn't try to de-HT
3812018-09-18T22:56:58 <TD-Linux> yes it does (returns 64)
3822018-09-18T22:57:12 <luke-jr> looks like boost's cpuinfo parsing would fallback to get_nprocs on POWER9
3832018-09-18T22:57:45 * TD-Linux kind of doubts that trying to not count HT cores is worth the pain
