  7 2017-10-25T00:27:48  <jtimon> aj: thanks for the feedback again, and of course thanks jb55 for the idea, my current TODO list for #10757:
  8 2017-10-25T00:27:49  <jtimon> 1) Move from range of heights to just a single height (wait to see if anybody asks for block hash alternatively), adapt tests
  9 2017-10-25T00:27:49  <jtimon> 2) Move results from numbers to strings (keep in satoshi), adapt tests
 10 2017-10-25T00:27:49  <jtimon> 3) Move from generate(101) to hardcoded blocks in tests
 11 2017-10-25T00:27:49  <jtimon> 4) Use at least 1 segwit tx to test the dunctionality

188 2017-10-25T14:57:05  <Grandpa_> Hello, - an old lowtech grandpa on the line here - hoping you guys can help me figure out what to do.  I have an old Bitcoin Core wallet with some old BTC coins in it. It haven't spent any or even touched the wallet (other than upgrading to Core 0.15.0.1 a few day ago) since May 2017 - prior to the Segwit implementation and the Bitoin Cash and Gold forks that I have been trying to follow through the media.
189 2017-10-25T14:57:16  <Grandpa_> Now I would like to transfer some to Bitstamp (the only place where I have an acct) in case I would like to sell a litle bit. But I would of course also like to NOT LOSE the Bitcoin Cash and Gold coins which now (as far as I am able to discern from media coverage) reside inside the belly of each of my old Bitcoins.  I've tried to make sense of Bitstamp's official statements but there isn't really any usable information ther
190 2017-10-25T14:57:25  <Grandpa_> So: Could someone among you PLEASE share some insight as to what to actually do? Since Bitstamp has automatically credited costumer accts with pre-BTCash holdings with one BTCash for each old BTC, do they also automatically do this with BTC that are transferred now? If not, how to go about it from inside Bitcoin Core (with the least possible difficulty and complexity for an aging chap who struggles with the technicalities i
191 2017-10-25T15:00:12  <gmaxwell> Grandpa_: Bitcoin Cash will not 'replay' your bitcoin transactions. You can send bitcoin without worrying about that.  Bitcoin gold doesn't really exist yet, but they claim that when it does it will also not be vulnerable to replay, so again, should be no reason to worry there.

193 2017-10-25T15:00:56  <gmaxwell> When you pay with your bitcoin core wallet, only the bitcoin will move... the Bcash (and presumably bgold) will just stay where they are.
194 2017-10-25T15:01:23  <Grandpa_> So you are saying that I can safely transfer som BTC to Bitstamp and they will take care of it_
195 2017-10-25T15:01:25  <Grandpa_> ?
196 2017-10-25T15:01:53  <Grandpa_> How can they stay where they are if the BTC are sent away?
197 2017-10-25T15:02:59  <gmaxwell> No, I am saying you can send btc to bitstamp and other currencies will not be effected.
198 2017-10-25T15:03:16  <gmaxwell> Grandpa_: because they are entirely seperate systems that diverged from bitcoin in the past, they will not see your transactions.

200 2017-10-25T15:03:34  <gmaxwell> (and, in fact, your bitcoin transactions are not compatible with them).
201 2017-10-25T15:03:38  <Grandpa_> Should a make a copy of my wallet before sending then?
202 2017-10-25T15:03:49  <Grandpa_> With the old balance?
203 2017-10-25T15:03:54  <gmaxwell> That could make it a little easier to later send the bcash/bgold.
204 2017-10-25T15:04:14  <gmaxwell> Though it is not strictly needed, as you can rescan your wallet on those systems.
205 2017-10-25T15:04:29  <Grandpa_> How else could I preserve the gold/cash?
206 2017-10-25T15:04:49  <gmaxwell> it would be preserved even if you didn't back up the wallet because the keys are never removed from the wallet.

208 2017-10-25T15:05:32  <Grandpa_> I mean, if I now send away some coins reducing wallet balance to 0 / could I later extract cash and gold from it_
209 2017-10-25T15:05:34  <Grandpa_> ?
210 2017-10-25T15:06:00  <gmaxwell> Yes, that is what I've been trying to tell you.
211 2017-10-25T15:06:08  <Grandpa_> Oh, my.
212 2017-10-25T15:06:27  <Grandpa_> Sound scary though.
213 2017-10-25T15:06:30  <Grandpa_> Sounds
214 2017-10-25T15:07:14  <gmaxwell> it isn't really-- these things are just totally seperate cryptocurrencies where they just happened to also pay everyone that owned bitcoin at a certian time on them.
215 2017-10-25T15:07:37  <gmaxwell> So its like importing the same private key into a litecoin and bitcoin wallet. They're still seperate.
216 2017-10-25T15:09:14  <Grandpa_> But the recommended path would, however, be to just make a copy of the wallet before sending? And then later on use it for the other two? How exactly would I go about it if I want to get rid of the bcash asap (which I dont like?)
217 2017-10-25T15:09:56  <sipa> can we move this to #bitcoin ?
218 2017-10-25T15:10:28  <Grandpa_> how do I do that?
219 2017-10-25T15:10:39  <Grandpa_> start there anew?

296 2017-10-25T19:26:47  <gmaxwell> well the things fixed in 0.15.0.1 wouldn't really make a lot of sense in that context... because ... they're fixed.

298 2017-10-25T19:29:30  <aj> gmaxwell: the sensible reason for basing on 0.14 is that rebasing 0.14->0.15 on top of btc1 is too hard; but that's embarassing to admit, and rebasing btc1 on top of 0.15 would also be embarassing
299 2017-10-25T19:36:20  <MarcoFalke> 0.15.0.1 only fixed the gui oob crash. The "peers.dat" crash will be fixed in 0.15.0.2.

332 2017-10-25T20:37:42  <sturles> I am on a 3G network, downgraded to GPRS speeds after exceeding daily quota limit.  Now my node has been stuck for hours on "Timeout downloading block [...] disconnecting".  Is it possible to make it more patient, or will I have to wait until after midnight for more blocks?  Does it keep the dowloaded part, or is it discarded before trying to download from the next node?
333 2017-10-25T20:42:03  <gmaxwell> discarded, unfortunately, though the timeout is 20 minutes, so if you can't transfer a block in that time you're going to fall behind regardless.
334 2017-10-25T20:43:20  <sturles> Would be nice if it could at least keep valid downloaded transactions in the mempool, to allow for a more compact block download next time.
335 2017-10-25T20:44:39  <sturles> It seems to download more than one block in parallel, which makes it more likely to time out.
336 2017-10-25T20:45:01  <Chris_Stewart_5> sturles: Perhaps you could use -blocksonly if you are on mobile?
337 2017-10-25T20:45:30  <sturles> I need the bandwidht for downloading two or more blocks in 20 minutes.

344 2017-10-25T20:47:36  <Chris_Stewart_5> sturles: I think it would eliminate your mempool problems, but it might not matter since you have to dl the entire block any way
345 2017-10-25T20:48:09  <sturles> I don't have a mempool problem that I am aware of.
346 2017-10-25T20:49:46  <sturles> How does sending transactions work with -blocksonly?  I guess fee estimation will be off, and privacy will certainly be worse since all unconfirmed transactions I know about are my own.

352 2017-10-25T21:00:46  <gmaxwell> sturles: it can't get anything from the partially sent block because its sent as a large single message. the bitcoin p2p layer deals with messages as big atomic units.

356 2017-10-25T21:02:19  <gmaxwell> sturles: its interesting to me that you had block downloads fail on a running node with a mempool. they should have been fetched via compact blocks and been fast to transfer.
357 2017-10-25T21:02:25  <gmaxwell> I wonder why it didn't.

364 2017-10-25T21:09:53  <gmaxwell> no progress is meaningless when its near 1, its just based on timestamps.
365 2017-10-25T21:10:23  <gmaxwell> sturles: right your mempool only learns about new txn coming in, and most txn getting confirmed now were broadcast quite a while ago (mempool is draining out)
366 2017-10-25T21:10:48  <gmaxwell> so probably a block came in after you were limited and had very few mempool hits, and you fetched it and couldn't manage it in 20 minutes.
367 2017-10-25T21:10:50  <sturles> height=491698 was downloaded at 17:48:40 UTC, seconds after my speed was downgraded.
368 2017-10-25T21:11:40  <sturles> I now have "blocks": 491699, which means one block has been successfully downloaded after that.
369 2017-10-25T21:12:42  <gmaxwell> you might end up back in sync if you -connect to a single peer. ... other peers sending you txn while you fetch that block might be making the difference.
