04:46 < waxwing> belcher, are you able to run general regtest tests? (like have ygrunner running or just start the regtest manually, then run the wallet tool and other scripts to test functionality)?
04:49 < waxwing> kristapsk, thanks for those latest PRs, i hope you don't mind if i'm not really focused on that stuff, between #544 and #536 there is tons of work to do and rebasing off master over and over is not too enthusing (i think i've rebased 536 6 times so far and will have to do a very very large rebase on 544 if/when that gets merged)
04:51 < kristapsk> waxwing, yeah, no hurries, would be cool to have them until next release (I just had dust attacked recently, that's the reason I wrote them)
04:55 < belcher> waxwing yes, yesterday i ran the entire test suite as in testing.md
04:56 < belcher> ygrunner didnt work for me a few months ago, but ill try again now/later
05:09 < waxwing> belcher, ok cool so the testing suite works now, do you know what changed?
05:09 < waxwing> or is it like, if there isn't an error, then it doesn't crap out with that weird error in bitcoin-cli stop?
05:10 < waxwing> wrt ygrunner i only refer to it because to me it's the easiest way to get everything up and running in one: you get a wallet with coins in it to use and the irc and bitcoind all ready for you
05:10 < waxwing> albeit in certain tests you don't need all of that. like testing wallet generation.
05:11 < waxwing> i'd still say that it would be far better for us to fix whatever prevents that from working and agree on a manual testing set up we can all use. 
05:11 < waxwing> kristapsk, have you used ygrunner to do tests? if not how do you test your new code (the user level stuff that isn't covered by the test suite)?
05:16 < kristapsk> waxwing, no, I usually do manual testing, non-cj stuff with testnet, for cj stuff use mainnet
05:16 < kristapsk> it's on my todo list, to get into this, but haven't done it yet
05:19 < belcher> btw the full test suite too 2 hours to run on my laptop, idk if thats normal, presumably a combination of HDD and slow/old CPU
05:19 < waxwing> yeah that's not normal at all. takes about 3 minutes here.
05:19 < belcher> but still i can run it before creating a big PR
05:19 < waxwing> did you clean out regtest directory?
05:20 < belcher> no i didnt
05:20 < belcher> good idea, that could help
05:20 < waxwing> all the same i'd say maybe just need to use newer hardware. that seems way over the top.
05:20 < waxwing> i mean development doesn't need stupid high end hardware but a lot of RAM is really useful i think .. and for bitcoin probably SSD is realistically needed, even for dev work.
05:20 < waxwing> i guess?
05:21 < waxwing> 5 minutes actually, not 3, i see pytest reports it.
05:21 < waxwing> also it does chew some CPU somewhere in the middle.

07:48 < kristapsk> waxwing, I use HDD almost everywhere, except my current laptop (where I do most of the development work), where I have datadir on NVMe SSD, but blocksdir on HDD
07:49 < kristapsk> I think there should be some problems if tests can run reasonably fast on a HDD
07:49 < kristapsk> s/can/can't/
07:49 < waxwing> kristapsk, how long does the test suite take on your machine?
07:50 < waxwing> i mean, i wouldn't have expected 2 hours instead of 5 minutes, just from SSD vs HDD
07:50 < waxwing> heads up to belcher especially but anyone else interested in coinswap stuff: https://gist.github.com/RubenSomsen/8853a66a64825716f51b409be528355f
07:53 < kristapsk> waxwing, you mean tests/run_tests.sh or more? I can test that one on RPi with all bitcoin data and ~/.joinmarket/ on external USB2 HDD, I think that should be the slowest machine I have currently
07:54 < waxwing> yes i just do `pytest .... ` from root dir but iirc run_tests.sh just wraps that.
07:54 < waxwing> pytest reports the time taken.
07:55 < waxwing> if it helps, this is the exact command for me: `pytest --btcconf=/home/waxwing/bitcoin.conf --btcroot=/home/waxwing/code/bitcoin/src/ --btcpwd=123456abcdef --nirc=2 --ignore test/test_full_coinjoin.py -p no:warnings`
07:56 < waxwing> it should collect and run 308 individual test cases.
07:56 < waxwing> no wait, that number depends on the PR you're testing, of course :)
08:06 < waxwing> kristapsk, also bear in mind, since you were mentioning datadir and blocksdir - this is all *regtest* development work, so not in any way affected by difficulties of performance of mainnet bitcoin
08:08 < waxwing> maybe it's a question of CPU churn. or maybe there are just a lot of hard disk writes or something.
08:10 < kristapsk> JM 0.6.2 tests on RPi are failing for me
08:11 < waxwing> ok. we wanted to find out how long it takes but .. that's also useful to know i guess :)
08:11 < waxwing> could you let us know the versions of all the tools (pytest etc), which is reported at the start of the run?
08:12 < waxwing> maybe you didn't see it in the backscroll, but this is what i have: platform linux -- Python 3.6.7, pytest-5.2.2, py-1.8.0, pluggy-0.13.0
08:13 < kristapsk> subprocess.CalledProcessError: Command '['bitcoin-cli', '-regtest', '-rpcuser=bitcoinrpc', '-rpcpassword=123456abcdef', 'stop']' returned non-zero exit status 28.
08:13 < kristapsk> don't think it's problem in python part
08:13 < waxwing> i think that's exactly what belcher reported
08:14 < kristapsk> probably RAM issues, as it has only 1G and mainnet bitcoind is running, although I don't see OOM kills in dmesg
08:14 < waxwing> at least, the first time. then he said he ran it again and it worked. i did ask, but i'm not sure if he knows what the delta was, maybe it isn't clear.
08:15 < waxwing> 1G does sound way too small yeah.
08:15 < kristapsk> well, it has 1.5G swapfile on USB HDD too :)
08:16 < waxwing> there are clunky things in the tests like sleep calls (where it's waiting for the regtest bitcoind to mine the next block).
08:16 < waxwing> although ... that doesn't relate to the error you both reported with bitcoin-cli stop
08:16 < waxwing> wait what is exit status 28
08:17 < waxwing> should ask the obvious questions :)
08:18 < kristapsk> I think I had this before, just don't remember how I solved it
08:25 < waxwing> just as a sanity check, i reran the tests against tag v0.6.2 and they do indeed pass, fine.
08:27 < kristapsk> yes, I've done v0.6.2 tests successfully on other machines, that shouldn't be the issue (although, all other machines was x86_64, not arm)
08:27 < waxwing> ok, good to know

13:20 < belcher> waxwing where did you see that github gist by RubenSomsen
13:21 < waxwing> belcher, oh sorry, i saw it on twitter and i should have posted the twitter link
13:21 < waxwing> because he has a diagram. i find the gist near unintelligible.
13:21 < waxwing> https://twitter.com/SomsenRuben/status/1259880548589240320
13:22 < belcher> ty
13:23 < waxwing> not that i'm claiming to completely understand it yet :) i find i have to spend a lot of time on this stuff because there are so many subtle variations in the mechanisms

14:32 < belcher> waxwing watch ruben's youtube video, it helped me understand it
14:32 < endthefed> hey guys, I am having trouble with finding a command that will sweap all mixing depths at one go
14:32 < belcher> such a command doesnt exist for privacy reasons endthefed
14:32 < endthefed> ah got it! thanks :) 
14:33 < endthefed> that was a nice podcast btw!
14:33 < belcher> :)

14:37 < belcher> waxwing i think i could summary ruben's protocol as "private key handover but with adaptor signatures"
14:37 < belcher> maybe thats a slight unfair summary, ill write an email to the mailing list shortly
14:39 < belcher> looks like ZmnSCPxj has already said "this is very similar to private key handover"
14:41 < MaxSan> can run JM behind tor quite well yes
14:57 < belcher> you know thinking about it, private key handover in coinswap is pretty amazing

15:54 < belcher> sorry about all the crashes in #544 waxwing lol
15:57 < waxwing> no worries i'm just hoping we can get your testing setup working otherwise it's just kinda hard.
15:59 < waxwing> although to be fair one could argue that's not *that* important - more important is doing the testing of the stuff which isn't in the test suite.
