00:24 Sudi       celeron55_: hey here is an example of what the event system looks like over the network
00:25 Sudi       http://ideone.com/7M8UeO
00:31 Sudi       celeron55_: ?
00:33 Sudi       hmm is he gone?
00:33 VanessaE   it should be right around 1:30am his time I think
00:34 VanessaE   make that 2:34am
00:36 Sudi       i see
05:36 hmmmm      yeow
05:36 hmmmm      i just got minetest to use 9gb of ram
05:36 hmmmm      and then it crashed
05:36 hmmmm      no idea what on earth happened
06:23 SitDog     Upgraded to a real chat client :)
14:00 Sudi       hey celeron55_ this is the event system i talked abou in action over the network
14:00 Sudi       http://ideone.com/CwUhBO
14:04 celeron55_ yes, and...?
14:05 Sudi       you wanted to know how it would handle events over the network
14:05 Sudi       thats how
14:06 Sudi       you can of course also bind class methods to events
14:13 celeron55_ doesn't look too special; just a regular C++ event system in a lazy "Doer" naming style
14:18 Sudi       true
14:18 Sudi       but it automaticly dispatches the events to the correct receivers
14:18 Sudi       on a nother host
14:20 celeron55_ which is, like, 20 lines of code to implement? 8)
14:21 celeron55_ i see it does use that funky templated way of making a class know the type of itself
14:21 Sudi       then i must have done something wrong
14:21 Sudi       its faster then dynamic cast
14:22 celeron55_ what does the implementation code look like that calls serialize() and throws it through the tubes?
14:22 Sudi       bc that is seriously more than 20lines of code :P
14:24 Sudi       celeron55_: on the lowest level http://ideone.com/w52iKj
14:25 celeron55_ that makes me want to see AppFrame::actions::Message_
14:25 Sudi       haha
14:26 celeron55_ you're like a human ctags; almost as good but way slower 8)
14:27 Sudi       thats all pretty old code
14:27 Sudi       have to find it
14:27 celeron55_ why have you created it in the first place
14:28 Sudi       i am using it in my personal projects
14:28 Sudi       here
14:28 Sudi       http://ideone.com/b53o9q
14:28 Sudi       the custom id feature is not used by the system
14:29 Sudi       that was for consistency over savegames
20:00 Taoki      celeron55: I tested your 043_support branch. Compiled it and ran a local server with two clients connected to it. Then with the client, I connected to a 0.4.3 server and everything worked well. Didn't spend time on for long but I could see players moving aroung and nothing bad happened
20:00 Taoki      Hope that helps make up for the mistake with changing those ID's :P
20:00 Taoki      Again, let me know if you need something else tested with that, else I can delete the zip with your code and wait for it to go upstream
21:13 celeron55  so, i created this thing: https://github.com/celeron55/minetest/blob/exp/src/util/template_serialize.h#L340 https://github.com/celeron55/minetest/blob/exp/src/util/template_serialize.cpp#L22
21:14 celeron55  which is used like this https://github.com/celeron55/minetest/blob/exp/src/nodedef.cpp#L336
21:14 celeron55  and i want comments from C++ programmers who understand it
21:15 celeron55  it would be used for serializing stuff, to get better backward and forward compatibility and make taoki less prone to mistakes
21:16 Taoki      celeron55: Now that I know what I did wrong, I won't do things like mixing ID's again.
21:16 Taoki      But a consistent system for the packages (and well marked one) is always good, so I approve otherwise
21:17 celeron55  i'm not really talking specifically about you, but about everybody who don't exactly know what they're doing
21:19 celeron55  also that kind of a format would help those who know what they are doing too, because it's less error-prone
21:20 celeron55  anwyay; i am interested if somebody here feels qualified enough to tell how that particular one would be bad, and what to possibly do instead
21:22 Taoki      BTW, I'm seeing another bug on VanessaE's server. Some torches are using the lua particles, but some smoke poofs are frozen in place and just sitting there
21:22 Taoki      Newly spaend particles seem to be good tho
21:22 VanessaE   I see that happen with all kinds of entities.
21:22 VanessaE   carts, smoke, slimes were doing it too.
21:22 Taoki      yeah. Might be a small problem with particles
21:23 celeron55  when do they stop, and when do they start updating again?
21:24 VanessaE   I haven't seen a predictable pattern.
21:24 Taoki      I can't tell. I just see some currently frozen in place, but also new poes which work normally
21:24 Taoki      No stuck ones disappearing and no new ones getting stuck currently
21:24 VanessaE   /clearobjects still gets rid of them, but that kills off carts too.
21:25 Taoki      Did you just do a /clearobjects on the server? Since I still see them
21:25 Taoki      Unless that's a client feature
21:25 VanessaE   no.
21:25 VanessaE   I did not.
21:25 Taoki      ok. Can you try one now to be sure? If you're ok with carts disappearing
21:25 VanessaE   sure.
21:26 VanessaE   executed.
21:26 Taoki      I still see the broken smoke puffs
21:26 VanessaE   command completed.
21:26 Taoki      ah no, done
21:26 VanessaE   they disappeared for me.
21:26 Taoki      It cleared them. And funny thing... it also made Sokomine move again
21:26 Taoki      Jump to a far location
21:26 VanessaE   ok
21:26 Taoki      Now I see her moving for the first time in 15 minutes... I thought she was afk
21:27 VanessaE   teleported to 1000^3
21:28 celeron55  can any of you see any errors in the client log, or server log?
21:29 VanessaE   lemme check
21:29 Taoki      sorry, not having a console open for my client
21:29 Taoki      but saw nothing odd in chat
21:29 VanessaE   What am I looking for in the log?
21:29 Taoki      anyway, since that clearobjects all is good
21:30 Taoki      BTW. Is it also a bug that when I die and respawn, I'm only taken back to the spaen point sometimes? Half of the time I respawn in the same spot
21:31 Taoki      So if I die in lava, I respawn and re-die there a few times until I'm also teleported back
21:31 VanessaE   Taoki: old bug.
21:31 Taoki      ok
21:31 Taoki      ah, bad smoke puffs again
21:32 Taoki      haha! They have a bounding box and I can punch them
21:32 Taoki      they even flash when punched
21:32 celeron55  "What am I looking for in the log?" <- you are looking at the case-insensitive string "error"
21:32 Taoki      killed the smoke buff by punching it many times :D
21:32 Taoki      *puff
21:32 VanessaE   celeron55:  16:10:42: ERROR[ServerThread]: ServerEnvironment::deactivateFarObjects(): id=39
21:32 VanessaE   m_static_exists=true but static data doesn't actually exist in (-5,0,7)
21:33 VanessaE   and one about me overriding the gameid.  that's it for "error" messages.
21:33 celeron55  that's an old bug, doesn't matter
21:33 celeron55  well, throw me the server address, i'll build master (once again...) and come see
21:33 Taoki      Smoke puff defeated! exp earned, 0.01 :P
21:33 VanessaE   ok
21:33 VanessaE   24.181.193.82 port 30000
21:34 VanessaE   has a fair number of mods but you knew that.
21:46 VanessaE   celeron55: if you would like to investigate that player texture glitch, the mod I'm using to provide it is sdzen's player_textures, here:  https://github.com/sdzen/player_textures
21:46 VanessaE   I do not know if failing to load a newly-added texture without a server restart is a bug in the engine or the mod.
21:48 celeron55  it's not a glitch
21:48 celeron55  it's minetest generating a placeholder texture on purpose when it doesn't have one
21:48 VanessaE   yes, but the file is there.
21:48 celeron55  you didn't restart the server
21:49 VanessaE   yep I know
21:49 celeron55  so you know exactly what happens; why do you call it a glitch
21:49 VanessaE   the reason I ask is, shouldn't the server just not bother looking for the file if it can't actually load it?
21:49 celeron55  the server isn't looking for it
21:49 celeron55  the client is
21:49 VanessaE   ahhhhh
21:49 VanessaE   gotchya
21:53 celeron55  this load time is painful
21:53 VanessaE   yup.
21:54 celeron55  i guess now this more like hanged completely
21:54 VanessaE   taoki and others seem to be doing ok save for lagging a bit
21:54 VanessaE   had to get sdzen un-stuck by forcing a respwn - I think he was "attached" to sokomine, who appears to be afk
21:55 Taoki      All I know is the server is laggy and slow for some reason. Might either be a slow connection to VanessaE or some mod causing bandwidth to hand
21:55 Taoki      **hang
21:56 VanessaE   CPU usage of the server is minimal (about 10% of the core it's running on), bandwidth is always good (30Mbps down, 3Mbps up, and I actually get those speeds on long, sustained transfers)
21:57 VanessaE   (well, 10 to 25% it seems, probably due to mods)
21:57 celeron55  how many items does the server have?
21:57 VanessaE   lesse..
21:58 celeron55  1416 are visible in the creative inventory; i wonder how many there are that don't get put there
21:58 VanessaE   damm it what was that string to search for
21:58 VanessaE   dammit*
21:58 celeron55  or, well, 14**
21:59 VanessaE   creative inventory size: 1395
22:00 celeron55  there are 1741 media files
22:01 VanessaE   sounds about right; most of the stuff in my mods have more than one texture per node
22:01 celeron55  hmm, there are roughly 2000 items
22:01 celeron55  quite exactly actually
22:02 Sudi       you should maybe think about texture maps
22:02 Sudi       bc texture switches are expensice operations
22:02 Taoki      nice one: If you right click as block like the chest to get a menu, if someone removes that block while its menu is still open for you, the emnu turns into a black background
22:02 Taoki      I mean only the background is left
22:03 Taoki      nticed that with the rail chest
22:03 celeron55  holy shit this lags now
22:03 celeron55  everybody is walking at a static position 8D
22:25 VanessaE   celeron55: yes, we see you chatting just fine
22:26 celeron55  your server doesn't seem to be able to get anything through to this client anymore, except replies to minetest's ping packets
22:27 celeron55  now it started to
22:32 celeron55  the chat seems to have a lag of like 2 minutes 8D
22:33 celeron55  or even more
22:33 VanessaE   ouch
22:33 VanessaE   I changed the server step as requested btw
22:33 celeron55  did you say it in the chat?
22:33 VanessaE   yes
22:33 celeron55  haven't seen that yet
22:33 VanessaE   "done."
22:33 celeron55  last thing i saw was MK going brb
22:34 VanessaE   I did it about 2 minutes after you asked
22:34 VanessaE   17:30:41: ACTION[ServerThread]: CHAT: <MirceaKitsune> brb in 5
22:34 VanessaE   17:30:52: ACTION[ServerThread]: CHAT: <celeron55> vanessaE: try setting dedicated_server_step to 0.2
22:34 VanessaE   17:32:48: ACTION[ServerThread]: CHAT: <VanessaEzekowitz> celeron55: done.
22:34 celeron55  ha, there it came
22:36 celeron55  minetest has one funny feature: the size of the output buffer is infinite
22:37 celeron55  of the network stack
22:37 celeron55  it can throttle the output and just grow the buffer infinitely and make an infinite lag on a reasonable RTT 8)
22:37 VanessaE   I wonder if that's necessarily a good thing :-)
22:37 celeron55  ah, now this works perfectly
22:37 celeron55  the 10/s object position send interval was too much
22:38 celeron55  ehm... now nothing comes through again
22:38 VanessaE   engine was choking off it's ...haha
22:38 Taoki      The chat in MT is dead, is it the lag?
22:38 VanessaE   70+ KB/sec outgoing now, which is a damn sight better than before btw
22:38 VanessaE   well it was, now ~18
22:39 celeron55  that much outgoing and nothing coming to me?
22:39 VanessaE   yup
22:39 celeron55  that's a nice connection you have there
22:39 VanessaE   that's UDP for ya :)
22:39 Taoki      no, chat isn't dead, everyone was just silent :P
22:40 celeron55  i hereby declare this server completely useless :P
22:40 VanessaE   I hereby declare your network code crappy :D
22:40 celeron55  fix it then
22:41 celeron55  or re-evaluate it's crappiness!
22:41 VanessaE   wish I could :(
22:41 celeron55  does your server host anything else than minetest
22:41 VanessaE   no.
22:41 celeron55  because i'd like to try pulling something via tcp from it
22:41 VanessaE   fwiw, everyone else is doing okay, chat is active, 5-6 seconds for people to answer, etc.
22:42 VanessaE   how would I go about making such available?
22:42 VanessaE   (I rarely run servers so I'm not well versed in that stuff.  Not since 10 years now)
22:42 VanessaE   maybe scp a file from my machine to you?
22:43 Taoki      funny thing: Chat is VERY fast and nearly instant. But everything else is lagging horribly
22:46 VanessaE   celeron55: see msg.
22:46 VanessaE   Taoki: weird.
22:47 Taoki      anyway, is anything still being tested? If not I think I'll log off from the server
22:47 Taoki      mmaybe try relogging once more if i catch anything special
22:47 VanessaE   not actively, per se.
22:48 Taoki      ok
22:48 VanessaE   heh, I was just about to restart the server.
22:49 celeron55  seems to pull >200kB/s
22:50 Taoki      it's ok, I'm out
22:50 VanessaE   that's about right
22:50 celeron55  even 300
22:50 VanessaE   I can sustain 380 kB/sec via rsync to more local servers
22:51 VanessaE   well, local-ish
22:51 VanessaE   (somewhere in the USA anyways)
22:52 celeron55  god i hate dolphin when it does this... 80% CPU usage for no reason, and it does not have session save/restore
22:53 celeron55  and i have 13 tabs open
22:55 celeron55  while true; do killall kio_thumbnail; sleep 0.1;
22:55 celeron55  nice fix
22:55 celeron55  +done
22:55 celeron55  any higher sleep and it will make that pop up for an infinite time, using all it can get
22:56 celeron55  or, well, pops it up for such a time that it has time to actually use CPU 8)
22:57 celeron55  (and would just suck it until the end of the world)
22:57 celeron55  at least minetest isn't this bad
22:58 VanessaE   heh
22:58 celeron55  it a) saves sessions, b) nothing else even matters after that, goddamnit
22:58 VanessaE   lol
22:59 celeron55  in software development, there are two options
22:59 celeron55  the first one is to not make bugs
23:00 celeron55  the second one is to make the software painless to restart
23:00 celeron55  best ones do both
23:00 celeron55  dolphin does neither
