10:26:12 <gbenson> are there settings/compile options that make it possible to run a node with under 4G ram, or is that a minimum? OOM killer gets me if I run with less:(
10:28:54 <moneromooo> It should be more than enough unless you're syncing historical blocks. If that's what you're doing, check --db-sync-mode, tell it to sync more often - it'll be slower though.
10:29:31 <moneromooo> Also check monerod --help for interesting things. Like... amount of memory to download new blocks before they're added. Forget the name.
10:29:43 <moneromooo> Fewer peers might also help.
10:33:32 <gbenson> it is syncing, does it use less when it's up to date then?
10:33:46 <moneromooo> Yes.
10:34:21 <moneromooo> Syncing means downloading lots of blocks, placing them in a queue, then adding them, typically 20 at a time. Plus syncing the DB every, er, lots.
10:34:42 <moneromooo> When you're just keeping up with new blocks, add a block at a time, sync after each block.
10:35:05 <moneromooo> Syncing more often while syncing historical blcks will kill performance, which is already not great.
10:35:16 <moneromooo> But play with it, and see what you can get away with.
10:35:35 <moneromooo> Or just keep > 4 GB till you're synced if you can, then lower.
10:39:30 <gbenson> yeah, I think I'll do that, it's over halfway so hopefully done in a few hours
10:41:22 <gbenson> would've been done already if I'd given the VM enough ram from the start :D
10:42:21 <gbenson> --db-sync-mode default is fast:async:250000000bytes, so that's presumably 250Mb I could lose some of
10:48:19 <moneromooo> FWIW sync speed is much faster at start for various reasons. Mostly tx volume being a trickle for the first few years.
10:48:34 <moneromooo> But the last few thousand blocks are much slower as more is checked.
10:50:26 <gbenson> does the database size on disk grow faster towards the end? it's at 54% using 20G disk for a pruned node, which would mean ~40Gb total *if* it grows at the same rate, but I was expecing more like 70G for a pruned node
10:51:18 <gbenson> I guess if the first blocks are smaller that'd explain why it syncs a good way in before the OOM killer gets it
10:52:30 <gbenson> afaict not setting --block-sync-size means it'll do 20 blocks at a time, but I don't know how big a block is so... :)
10:54:32 <moneromooo> A pruned DB is 60 ot 65 GB or so I think.
10:55:30 <moneromooo> Most early blocks are empty. Most late blocks are not. But IIRC adds are made 200 blocks at once for the early chain.
10:57:02 <gbenson> ah, is that what BLOCKS_SYNCHRONIZING_DEFAULT_COUNT_PRE_V4 is
10:58:03 <gbenson> why did empty blocks get added? (sorry if this is an idiot question)
10:58:38 <moneromooo> To keep track of difficulty.
10:59:04 <moneromooo> And if you add a rule that says you can't add empty blocks, miners will start adding their own dummy tx, so no gain, and a loss from spam.
12:03:47 <gbenson> I never did quite figure out difficulty, I should probably re-read the original bitcoin paper again but the math was over my head the last time I tried :/
14:40:51 <parazyd> Hey, what is the reason here that xmrig closes the connection after receiving a job? https://termbin.com/8e5d
14:40:59 <parazyd> Context, I'm trying to write a mining proxy
14:45:32 <sech1> "target":"0x2" doesn't look right
14:46:09 <sech1> and "id" field is missing in the response
14:46:40 <parazyd> sech1: The stratum doc says it's a notification, so there should be no ID: https://github.com/xmrig/xmrig-proxy/blob/master/doc/STRATUM.md#job
14:48:14 <parazyd> The same disconnect happens when I use for example "b88d0600" for "target"
14:52:34 <sech1> Try to connect to xmrig-proxy and find the difference in what you send and what xmrig-proxy sends in response to "login" message
14:53:54 <sech1> oh, you definitely forgot to send "seed_hash" in the job. RandomX requires it
14:54:15 <sech1> and "height"
14:57:40 <sech1> I recommend to check what P2Pool replies to login message: https://github.com/SChernykh/p2pool/blob/master/src/stratum_server.cpp#L309C74-L309C74
14:57:48 <sech1> There's quite a different in what it sends
14:57:55 <sech1> first of all, it's not "params" but "result"
14:58:22 <parazyd> So it means that STRATUM.md is outdated
14:58:37 <sech1> absolutely
14:58:39 <parazyd> Thanks for the link
15:00:54 <sech1> actually, you should've looked at https://github.com/xmrig/xmrig-proxy/blob/master/doc/STRATUM.md#example-success-reply
15:01:09 <sech1> with the addition of "algo", "seed_hash" and "height" fields
15:01:20 <parazyd> oh
15:01:28 <parazyd> Yeah missed that one
15:02:45 <sech1> It's outdated because it doesn't mention "algo" extensions, but it's mostly accurate
15:14:44 <parazyd> Alright, will see where that gets me
16:00:54 <parazyd> sech1: It's getting me _somewhere_ now: https://termbin.com/25ji
16:01:06 <parazyd> I'm trying this just on a local-only monerod testnet node
16:24:57 <parazyd> AFAICT it means that seed_hash is invalid
16:25:02 <parazyd> What should it be on height 1 though?
16:25:20 <parazyd> Since getblocktemplate() gives me an empty string for seed_hash on height 1
16:29:32 <sech1> RandomX was activated at later height.
16:30:11 <sech1> 1978433 for mainnet, 1308737 for testnet
16:30:17 <parazyd> ahhh

23:16:32 <Psylocybin42> Hello, I'm forking cryptonote and am having difficulty with the gui wallet.  I have the core compiled and working on ubuntu16 and win10, and the gui wallet working on ubuntu 16.  But I am not able to get the gui wallet to compile on windows.  I make the symbolic link and git submodule, and these are the commands I use to cmake and build:
