[snowblossomcoin/snowblossom] #88 adding pool failover to pool miner
2018-06-20 07:01:31
Tyler Boone
well, there is pool miner failover. It's probably not ideal because it won't try and occassionally try to get back on your preferred pool, but it works.

@Clueless just gnu coreutils
2018-06-20 07:13:03
Tyler Boone
bah, stupid behavior with precache where it will always connect to the second host because it will always hit the case of looking like it was stalled.
2018-06-20 07:14:04
Rotonen
also thought up a better examples of localization: if a culture expects a different introduction order of things for logic to hold water, the order of wizard pages will have to be shuffled and the contents reworked what they do to television program formats when they do a local version of something

Rotonen
@Tyler Boone i like that change as it makes this a stability competition between the pools
2018-06-20 07:15:56
Tyler Boone
haha. yeah if a lot of people have that set up then if you restart your pool you will lose a lot of miners
2018-06-20 07:16:08
Tyler Boone
not really the behavior I want though...
2018-06-20 07:17:23
Rotonen
work on a feature branch for stuff like that so it’ll not end up in production if an emergency release needs to get cut
2018-06-20 07:17:38
Tyler Boone
I pretty much always use branches
2018-06-20 07:17:52

fireduck is the "party in master" dude
2018-06-20 07:18:21
Tyler Boone
Alright, I'm off to bed. wife's getting impatient.
2018-06-20 07:18:25
Tyler Boone
ttyl sir
2018-06-20 07:18:31
Rotonen
oh that was a pr, read it as a commit note as a lot of things are
2018-06-20 13:50:44
Fireduck
party in master 24x7
2018-06-20 13:51:01
Fireduck
google got me in that habit
2018-06-20 13:51:38
Fireduck
I can't understand how a company that large works with that many people just checking into master but somehow it does
2018-06-20 14:31:50
Rotonen
staggered a|b testing style deployment and everyone is liable? (pure guess)
2018-06-20 14:59:22
Fireduck
heavy reliance of pre-checking automation
2018-06-20 14:59:28
Fireduck
to do builds and run tests
2018-06-20 15:10:13
Rotonen
obviously someone there was very good at both building processes and pressing people into the mould
2018-06-20 15:10:41
Rotonen
tough stuff, designing for the human element
2018-06-20 15:10:42
Tyler Boone
it still seems weird to me. how can a developer work on 2 things at once?
2018-06-20 15:11:07
Tyler Boone
I mean... it's throwing away the single biggest advantage of git
2018-06-20 15:12:04
Rotonen
many ways to rome
2018-06-20 15:12:43
Rotonen
also the company is older than git
2018-06-20 15:13:52
Tyler Boone
doesn't mean they don't use it.
2018-06-20 15:14:18
Tyler Boone
Microsoft is too, but git is now the most prevalent repo
2018-06-20 15:17:00
Tyler Boone
but actually yeah you are right. if they aren't on git, it makes total sense
2018-06-20 15:17:41
Fireduck
They are on g4 which is a rewrite of perforce
2018-06-20 15:26:21
Fireduck
Devs do two things at once by having multiple checkouts in these citc things. Client in the cloud.
2018-06-20 15:26:32
Fireduck
Some do use branches
2018-06-20 15:26:42
Fireduck
Or a git proxy thing
2018-06-20 15:27:51
Fireduck
It worked very well. I spent most of my time fighting people not tech.
2018-06-20 15:39:14
Tyler Boone
that's fine. They did an internal implementation that gave them the same thing as git branches
2018-06-20 15:39:23
Tyler Boone
so it's actually like they were using pull requests :slightly_smiling_face:
2018-06-20 15:40:29
Fireduck
Yeah. You could clone or run someone's citc client to check it
2018-06-20 16:15:36
Rotonen
i was pointing out their legacy for their workflow predates the modern hot thing and big ships turn slow, and whatever they do seems to be working out ok for them
2018-06-20 16:45:28
Clueless
@Tyler Boone or I can be a dick and have two pools prepared. `http://snowday.fun` and not lose any
2018-06-20 16:49:24

Add ability to split the main snow field file into chunks and put them on separate media. This will allow people to: 1. put some stuff in memory filesystems 2. use storage that doesn't quite fit (example, 256gb field on 250gb ssd) etc. If we do this nicely, we allow a ton of flexibility without having to special case it all in the miner.
2018-06-20 16:50:47
Fireduck
nice, the git integration edits the post
2018-06-20 16:51:00
Clueless
yeah, I love it
2018-06-20 16:51:15
Clueless
@Fireduck can you connect the discord thing? People would like to see it.
2018-06-20 16:51:17
Rotonen
@Clueless that’d just be being well prepared rather than a dick, IMO
2018-06-20 16:51:40
Clueless
@Rotonen Kindergarten once told me I should share.
2018-06-20 16:51:41
Fireduck
yeah, when I ran HHTT I had three endpoints up
2018-06-20 16:52:24
Clueless
I'm playing around with their "floating ips" I should be able to push people onto a different VM before spinning this one down.
2018-06-20 16:53:12
Fireduck
So a work unit sent to a miner only has any meaning to the mrplow that issued it
2018-06-20 16:53:19
Fireduck
it is basically an ID number
2018-06-20 16:53:32
Fireduck
which has to be matched up to the rest of the block header and block that it relates to
2018-06-20 16:53:59
Fireduck
so currently, nice active-active setup isn't really possible
2018-06-20 16:56:13
Clueless
I figured, so it'll interrupt the miner slightly, but it shouldn't fail over.
2018-06-20 16:56:21
Clueless
in this case, it's a manual switch
2018-06-20 16:56:58
Fireduck
/poll "Continue to maintain SnowBlossomMiner with feature parity to PoolMiner?" "Yes" "No"

Is there any difficulty in maintaining feature parity?
2018-06-20 16:58:15
Clueless
Is there a way you can make Miner extensible?
2018-06-20 16:58:28
Fireduck
A little, we are going to be adding new features for things like failover, reading from multiple locations
2018-06-20 16:58:31
Clueless
Then when a common feature comes out, you only put it in Miner, but PoolMiner inherits it
2018-06-20 16:58:32
Fireduck
and other improvements
2018-06-20 16:58:48
Fireduck
Yeah, they work differently enough that it would be difficult.
2018-06-20 16:58:57
Fireduck
One deals with work units, the other with whole blocks
2018-06-20 16:59:03
Fireduck
doable, but maybe not worth it
2018-06-20 16:59:24
Fireduck
If someone wants to solo mine, they can always spin up a plow and point a pool miner at it
2018-06-20 16:59:56
Clueless
seems reasonable to me.
2018-06-20 17:09:45
Tyler Boone
@Clueless, having a backup pool isn't a "dick move", it's totes legit. just convince your users they should put those first
2018-06-20 17:33:58
GitHub
That way the java code can do the headers and proof work while allowing other binary mining programs.
2018-06-20 18:15:22
Clueless
l assume the pool_host config value survive spaces `pool_host=http://snowday.fun`
2018-06-20 18:16:24
Tyler Boone
you make funny assumptions
2018-06-20 18:16:42
Tyler Boone
adjust your algorithm to "assume dumbest thing"
2018-06-20 18:23:46
Fireduck
I am using some sort of java properties parser
2018-06-20 18:23:51
Fireduck
I don't actually know what it does
2018-06-20 18:26:34
Clueless
well, I'll test it
2018-06-20 18:26:57
Clueless
just firewall connections out to pool1, and see if the poolminer connects to pool2
2018-06-20 19:27:31
Rotonen
i’d not even assume it survives non-punycode i18n domains
