17:13 sfan5 guess that happens when you get carried away while merging stuff

17:55 scr267 Interesting bug:
17:55 scr267 terumet and basic_materials on the same server seem to cause a segfault during some mapgen
17:56 scr267 i don't think I have the latest basic_materials so I will try again with that in a bit... just double checking.
18:05 scr267 Looks like the latest basic_materials seem to improve the situation.
18:23 fluxflux scr267: interesting. we've used those mods together for a long time and have never seen an issue like that. you have a stack trace anywhere?
18:25 kurtzmusch joined #minetest
18:30 scr267 fluxflux, good to know... nope, I don't have a stack trace, at least not yet.

18:56 scr267 fluxflux, a gdb session didn't give me much...
18:56 scr267 Continuing.

18:56 scr267 [Inferior 1 (process 5233) exited with code 01]
18:56 scr267 (sorry for spamming)(
18:57 fluxflux @fluxflux mmm i was thinking more like the tail of minetest's debug.txt file
18:57 scr267 ah it has nothing :(
18:57 scr267 I should change the debug level adn try again
18:58 fluxflux mmmm if there's a stack trace, it'll show up w/ the default settings
18:58 sfan5 minetest "crashed" in a way that made it exit cleanly?
18:58 fluxflux if it's really crashing hard, that's something else...
18:58 Krock that's not a crash. sane error code 0 exit
18:59 Krock err
18:59 Krock that's two digits (I can't read btw)
18:59 Krock scr267: bt
18:59 Krock also bt with a debug build
19:00 scr267 Krock, ok ill check.
19:00 scr267 segfault
19:00 scr267 Sep 10 15:00:06 aurelium-dev systemd[1]: minetest.service: Main process exited, code=killed, status=11/SEGV
19:00 scr267 Sep 10 15:00:06 aurelium-dev systemd[1]: minetest.service: Failed with result 'signal'.
19:00 scr267 Sep 10 15:00:06 aurelium-dev systemd[1]: minetest.service: Service RestartSec=100ms expired, scheduling restart.
19:00 scr267 Sep 10 15:00:06 aurelium-dev systemd[1]: minetest.service: Scheduled restart job, restart counter is at 1.
19:00 scr267 let me try bt
19:00 Krock there's pastebin btw
19:01 Krock perfectly suited for long dumps
19:02 scr267 sorry yes you are right.
19:02 scr267 i could have just pasted that one line anyway
19:05 sfan5 if it did indeed segfault previously, then it didn't do so in your gdb session
19:05 sfan5 the output would be different
19:06 fluxflux scr267: also, what build are you running? and that there were 6 threads makes me think you have num_emerge_threads > 1; what happens if you set it to 1? (our server w/ terumet, basic_mats also has 4 emerge threads, so that's not necessarily the issue, but...)
19:08 scr267 Back in a minute, I'm installing the rpms for the debug sources
19:08 scr267 in order to run a proper gdb session
19:08 scr267 fluxflux, its a custom build
19:08 scr267 yes num_emerge_threads is a bit higher
19:09 scr267 now that I think about it, I wonder if it matches the max numbers of cpu on the VM.
19:09 scr267 hum maybe it doesnt
19:09 scr267 wonder if that would be an issue
19:09 fluxflux scr267 what commit is your build based on?
19:09 scr267 num_emerge_threads = 3
19:09 scr267 stable_5
19:10 fluxflux so should be more or less 5.0.1, right?
19:10 scr267 yes
19:11 scr267 gah, gdb gives me a list of packages to install and dnf tells me they are already installed...
19:11 scr267 grrrr
19:12 scr267 im going to set num_emerge_threads to 1 and try this again.
19:13 fluxflux https://github.com/minetest/minetest/blob/76325d0ba925cfdd18e387ae96d27921136e98e5/minetest.conf.example#L2996
19:16 scr267 LOL, ok... i'll keep that in mind... I'm trying to reproduce ... I got another crash but Im not sure if its the same now.
19:29 scr267 https://paste.fedoraproject.org/paste/TFtC5PuiKejb8t9e9OzYEA
19:30 scr267 Now I'm getting a completely different error regarding some dungeon_loot generation.
19:30 sfan5 fixed in 5.0.1
19:31 scr267 Both my minetest and minetest_game folders are up-to-date with stable-5
19:31 scr267 Odd!
19:32 Krock update mtg
19:32 Krock apparently not so up to date
19:33 fluxflux yeah, that's my theory on that too
19:33 Krock stable-5 yes but maybe not 5.0.1
19:33 fluxflux terumet does register a bunch of things w/ dungeon_loot, it's entirely possible that one of them is mis-named
19:34 scr267 so I should update mtg again?
19:34 scr267 should I switch to another branch?
19:35 sfan5 what's the last commit in your mtg checkout?
19:35 fluxflux scr267: what's the commit (hash string thing) of mtg you're using now?
19:35 scr267 commit d6a66860af6fc39957d8e947824b9c56c3686b8e (grafted, HEAD -> stable-5, tag: 0.4.17.2, tag: 0.4.17.1, tag: 0.4.17, origin/stable-5)

19:35 scr267 Date:   Sun Apr 8 09:57:00 2018 -0700
19:35 scr267 that seems a bit old
19:35 scr267 !?!
19:36 sofar stable-5
19:36 sofar you're not on master
19:36 sfan5 it appears you have created a stable-5 branch yourself that contains the last 0.4.17 commit
19:36 sfan5 or something like that
19:36 sofar doesn't mean it's the latest commit either
19:36 sofar commit dates can be in random order
19:37 scr267 ok ill remove that folder and try it again
19:38 scr267 there, all fixed up... ill try that again
19:49 scr267 got a completely different error now something about a terumet trying to access a global value from 3darmor
19:49 scr267 huh
19:49 scr267 oh well
19:56 BurningPrincess joined #minetest
20:01 fluxflux scr267 maybe update 3d_armor?
20:03 scr267 Yes, that's no longer related to the previous issue... I agree... I have a ton of mods to update anyway, so I'm guessing im going to run into a few more errors...
20:03 scr267 I'll stop pestering you guys... thanks for all the help btw
20:07 Krock !next
20:07 MinetestBot Another satisfied customer. Next!

20:48 aldenp hey, is there anything to be done about lag?
20:49 aldenp I've been having pretty terrible latency; my internet connection isn't great but it isn't 4-second-delay bad
20:49 aldenp I know there's no foolproof way of fixing this than "get better internet", but are there any config options I can use that might even slightly optimize things?
20:54 scr267 is it server side lag or client side lag?
20:54 scr267 What is your 'lag' like when you type /status ?
20:55 aldenp max lag is 1.06; I'm playing on pandorabox, which is laggy for sure but according to other players online right now not nearly as laggy as what I'm experiencing
20:55 aldenp I have lag issues on other servers as well so it's definitely client side
20:56 scr267 Mainly that would be connection related.
20:56 scr267 You could maybe try to increase the cache?
20:56 scr267 but I'm not sure how much effect that would have anyway.
20:57 scr267 If you ping the pandorabox server IP, what type of latency do you get?
20:57 aldenp first few packets have a latency of almost 3 seconds, but subsequent packets only around 200ms
20:57 scr267 I get around 130 ms
20:57 scr267 3 seconds?
20:57 scr267 ouf, are you on linux?
20:58 aldenp only for ~1-2 packets when starting the ping, after that it's sensible latency lol
20:58 aldenp yes running Gentoo
20:58 scr267 install mtr
20:58 scr267 and then simply run $ mtr pandorabox.io
20:58 aldenp ah ok I've been looking for a tool like this
20:58 scr267 It will do a continuous ping and show you the averages, standard deviations and etc..
20:58 aldenp neat
20:59 scr267 My guess is there is something somewhere that's causing some packets to drop or get very slow
20:59 cdde joined #minetest
20:59 scr267 You can leave it on for a while too without causing any issues... it'll just give you a better idea of how bad it gets
21:00 aldenp ugh it installs with a gtk interface by default, time to recompile lol
21:00 aldenp ~~I could use --curses like a sensible person but nah~~
21:02 aldenp joined #minetest
21:04 scr267 Oh I just use it on the cmd line
21:04 scr267 I didn't realize there was a gui for it.
21:05 scr267 Anyway, I have to go.
21:05 fluxflux aldenp: i assume you're aware of the pandorabox's grafana page?
21:05 fluxflux aldenp: and you on wifi or wired?
21:05 aldenp yes
21:05 aldenp I'm on wireless
21:06 fluxflux any ability to plug into a cable instead? makes a big difference for some players, but not always possible...
21:06 aldenp believe me I wish I could
21:06 aldenp I made the mistake of buying a laptop with no ethernet port
21:06 fluxflux it's getting harder to get them w/ one...
21:07 aldenp yeah, it sucks
21:08 aldenp I need to get a fancy USB-C dock for power+ethernet+monitor+usb, since the routine of unplugging three different cables on a daily basis to pack my laptop is getting frustrating lol
21:09 aldenp unfortunately my current laptop doesn't have a thunderbolt 3 port either, just the old USB-C :(
21:10 fluxflux and the issue is most likely actually latency, and not the FPS drops that a lot of people call "lag"?
21:10 aldenp I'm aware of this :D
21:11 aldenp btw is it normal for my ISP to be doing 6 hops before passing off my packets
21:11 fluxflux i've got a lot of settings i've tailored for the FPS issues, but not so much for bad bandwidth... will take another look though
21:11 aldenp so 6 hops in my ISP followed by another 6 hops through HE
21:11 fluxflux 6 hops in your ISP can be normal
21:11 aldenp ok
21:11 aldenp FPS isn't a problem for me fortunately
21:11 fluxflux especially if it's a large company
21:13 aldenp hm, pandorabox is overseas, I didn't realize
