00:00 VanessaE is there some common point where all of these sources could be piped through in the future, so that we don't have to fix this in multiple places?
00:06 ShadowNinja VanessaE: What do you mean?
00:06 VanessaE ShadowNinja: see your /msgs
00:07 ShadowNinja Seems that patch doesn't work...

03:52 hmmmm https://github.com/kwolekr/minetest/commits/master
03:52 hmmmm so that's:
03:52 hmmmm https://github.com/kwolekr/minetest/commit​/a439343844cf821e4922e23f1638b92e2cfb14ac

03:52 hmmmm https://github.com/kwolekr/minetest/commit​/2927a327cabe4feddc0aeea0f4111d888560612f
03:53 hmmmm comments?  concerns?
04:04 hmmmm I'm sure a change this big is going to break something, just no idea what at the moment
04:04 hmmmm it seems to be fine in my own tests
04:04 hmmmm of course, people who specified mapgen-specific flags in their configurations are going to lose that now unless they manually specify mg*_spflags.  i'd note that in the release.
04:05 hmmmm this is the best and cleanest way forward though, it's worth a minor inconvenience like that
04:05 hmmmm btw I don't want to do a release for another month or so, so we have a decent amount of 'field time' for big changes like this and what sapier's working on right now

15:13 ShadowNinja Megaf_: Known issue that has been discussed.  Some old clients violated the protocol in terms of sending TOSERVER_RECEIVED_MEDIA, and the new net code doesn't like that.  Reconnect when you have all the media loaded, or update your client.
15:15 VanessaE ShadowNinja: this appears to be unrelated to 1134, see #minetest...
15:16 VanessaE er 1132.
15:18 RealBadAngel joined #minetest-dev
15:19 RealBadAngel hi
15:19 VanessaE hi
15:19 RealBadAngel have anybody experienced problems with building from git?
15:19 VanessaE building, no, but a lot of people are having trouble running it.
15:20 RealBadAngel for me game starts with gray screen and no world at all
15:20 RealBadAngel both in minimal or  minetest_game
15:20 VanessaE it seems you're not the only one.
15:20 VanessaE #1134
15:20 ShadowBot https://github.com/minetest/minetest/issues/1134 -- Server not sending any map/world to clients - 2927a32
15:21 VanessaE and #1132
15:21 ShadowBot https://github.com/minetest/minetest/issues/1132 -- 0.4.9 (sometimes) failes to connect to old as well as latest server due to missing TOSERVER_RECEIVED_MEDIA
15:21 VanessaE oh shit
15:21 VanessaE I can't do it now either
15:21 VanessaE singleplayer, brand new world ... DEAD!
15:21 RealBadAngel great
15:21 VanessaE "Houston, we've had a problem."
15:22 RealBadAngel i just wanted to test skybox thingy
15:22 VanessaE I am at git HEAD right now on my client.
15:22 VanessaE just updated a few minutes ago
15:22 RealBadAngel it also works kinda weird
15:23 ShadowNinja hmmmm: Maybe you should remove the "<mgname>_" prefix from spflags?
15:23 VanessaE hmmmm: youbroke the mapgen - you broke the bloody mapgen! :P
15:23 VanessaE (ref:  Galaxy Quest)
15:29 VanessaE oh crap
15:29 VanessaE this breaks ALL of my old maps
15:29 VanessaE nothing whatsoever works
15:29 VanessaE it ain't mapgen that's broke
15:29 VanessaE it's something else
15:30 Anchakor_ joined #minetest-dev
15:32 zat joined #minetest-dev
15:40 ShadowNinja EmergeThread?
15:41 ShadowNinja s/Thread/Manager/
15:42 VanessaE my guess, yeah
15:42 VanessaE no map loads at all
15:42 VanessaE grey screen plus my wielded pick and hotbar
15:42 VanessaE that's all I get.
15:42 VanessaE all of my maps are like that
15:42 VanessaE rolled it back to 284fc as Megaf suggested, and it works fine there.
15:42 VanessaE (it = my client/singleplayer)
15:43 VanessaE hah, in the brand new map that didn't work before, now that it works, turns out I spawned on top of a tree :D
15:45 RealBadAngel im trying different skyboxes found on the net and why the heck top image has to be rotated by 90 deg when used in game?

18:10 sapier hmmmm we should decide about a consistend naming scheme for non exceptioning functions
18:13 sapier I suggest using NoEx as it's used throughout current code while a quick look didn't show up any current usage of trySOMETHING
18:19 khonkhortisan joined #minetest-dev
18:25 PilzAdam sapier, #1132 map doesnt load for me either
18:25 ShadowBot https://github.com/minetest/minetest/issues/1132 -- 0.4.9 (sometimes) failes to connect to old as well as latest server due to missing TOSERVER_RECEIVED_MEDIA
18:26 PilzAdam singleplayer, latest master
18:26 sapier without curl?
18:26 PilzAdam I have curl
18:26 sapier strange
18:27 PilzAdam does the world load for you?
18:27 sapier right now I assume this to be multiple issues
18:27 whirm joined #minetest-dev
18:27 sapier As far as I remember yes, but I'm retrying
18:30 sapier yes still works for me
18:31 sapier well 0.4.9 will still fail until we decided if and case we do how to do a server side workaround
18:32 sapier PilzAdam do you have latest git client and server?
18:32 PilzAdam yep
18:32 sapier and singleplayer?
18:32 PilzAdam yes
18:32 sapier so where's the difference
18:32 sapier mods?
18:33 PilzAdam minimal
18:33 sapier default settings or something special?
18:33 PilzAdam define "special"
18:34 sapier someone mentioned a setting about disabling remote media. I haven't had a look what's this about
18:34 PilzAdam https://gist.github.com/Pil​zAdam/b76dcc80b8513115cb76 my minetest.conf
18:35 sapier nothing obvious in there
18:36 sapier can you do a wireshark recording?
18:36 PilzAdam any special settings for wireshark?
18:37 sapier does singleplayer use 30000 too? if this is true you could limit to that port
18:37 PilzAdam no, it creates a random port
18:37 sapier does it happen on local server too?
18:38 RealBadAngel <VanessaE> the broken game is easy enough to roll back to a working version
18:38 RealBadAngel <VanessaE> git reset --hard 284fc0b88569075187019a1b311312e64e79d937
18:38 PilzAdam .... no
18:38 PilzAdam it works when starting the game from the server tab
18:38 RealBadAngel the current git isnt working at all
18:39 sapier that's really strange
18:39 PilzAdam well, I only got one block
18:39 RealBadAngel gray screen, no world loading
18:39 RealBadAngel no matter the game selected
18:39 OldCoder joined #minetest-dev
18:39 sapier wait .. if you sometimes get data this may be a plain deadlock
18:40 VanessaE when the map greys-out, the chat and chat commands still work.
18:40 PilzAdam you still need that wireshark log?
18:40 sapier no with this information a gdb backtrace would be way more helpfull
18:42 sapier and in best case show me and don't quit while I look at it
18:42 PilzAdam https://gist.github.com/PilzAdam/8809700
18:43 sapier :-( wrong way ... doesn't seem to be a deadlock
18:44 sapier I guess I'll need the wireshark recording
18:45 sapier right now I assume we're talking about two issues 1132 can't happen in latest git
18:46 sapier ok I don't know about a way it could happen in latest git
18:54 sapier PilzAdam can you switch to https://github.com/minetest/minetest/commi​t/458045d49fd96cf19bdd61b2f8dbdbc0fd11b587 and check if it's broken there too?
18:54 khonkhortisan joined #minetest-dev
18:55 sapier didn't realize the mapgen stuff is already in, I don't have that code in my version yet
18:55 Megaf_ sapier: Hi
18:55 Megaf_ get the latest git, compile however you want, use any mapgen
18:55 sapier and result?
18:55 Megaf_ start the server and try to login, local or remote
18:56 Megaf_ gray screen
18:56 Megaf_ try single player, gray screen
18:56 sapier ok does switching back to the version I mentioned above work?
18:56 PilzAdam sapier, compiling
18:56 Megaf_ https://github.com/minetest/minetest/issues/1134
18:56 Megaf_ sapier: read all comments
18:57 PilzAdam (btw, wireshark is strange, it doesnt like my filters to port 30000)
18:57 Megaf_ switching back to 284fc0b as I was using before works fine
18:57 sapier interface or display filter? those use different notation
18:57 PilzAdam Megaf_, I think sapier already knows about the issue by now
18:57 Megaf_ I know
18:57 PilzAdam sapier, that one work
18:57 PilzAdam +s
18:58 sapier ok so no need for a wireshark trace
18:58 Megaf_ sapier: PenguinDad tried some different commits and said it was working till a439343
18:58 Megaf_ But I can't confirm that
18:58 sapier we've got two different issues ... the one from 1132 we already understand what happens ... and your new one which was added yesterday
18:59 PilzAdam so hmmmm broke it?
18:59 RealBadAngel btw, adding one line of code: https://www.youtube.com/watch?v=​_UO_8U39qIM&amp;feature=youtu.be
18:59 sapier there are only his commits after that version but of course it could be some side effect too
19:00 sapier does anyone else except me dislike adding a new notation for non exceptioning functions too?
19:02 PilzAdam RealBadAngel, do the clouds move in a circle arround you?
19:02 RealBadAngel yes
19:02 PilzAdam lol
19:02 RealBadAngel it add simply rotation to the skybox
19:02 sapier do you wanna add a tornado/hurrikane? *g*
19:03 RealBadAngel after this line: https://github.com/minetest/minete​st/blob/master/src/game.cpp#L2487
19:03 RealBadAngel add this: skybox->addAnimator(smgr->createR​otationAnimator(v3f(0,.0025,0)));
19:03 Megaf_ RealBadAngel: skybox, is that a mod?
19:03 RealBadAngel http://www.sendspace.pl/fi​le/2c444da19c4fdf67d26b0d4
19:04 RealBadAngel this is sample skybox
19:04 RealBadAngel the one i used in video
19:04 sapier is that leaves disortion already part of minetest?
19:05 Megaf_ sapier: lol, yes it is
19:05 RealBadAngel Megaf_,  https://github.com/minetest/minetest/commi​t/86a6cca3cf641fc2c88184ad26d2be3d7e7460f7
19:05 Megaf_ it a "shader"
19:05 sapier never seen it :-) but it's great
19:05 Miner_48er joined #minetest-dev
19:05 Megaf_ sapier: waving stuff in shaders menu
19:06 sapier if I didn't always have to fix basic bugs I'd have more time to look at cool new stuff ;-)
19:06 Megaf_ RealBadAngel: That's awesome. Too bad we can't implement that on server side
19:07 Megaf_ I know how you feel
19:07 VanessaE guys can we get 1132 and 1134 dealt with first?
19:07 sapier PilzAdam about #1132 I guess I can fix the issue by version bumping as we bumped version prior 0.4.9 too
19:07 ShadowBot https://github.com/minetest/minetest/issues/1132 -- 0.4.9 (sometimes) failes to connect to old as well as latest server due to missing TOSERVER_RECEIVED_MEDIA
19:07 RealBadAngel server sets the sky for players...
19:07 VanessaE wtf good are skyboxes and shaders if the game can't even start?
19:08 sapier I don't understand mapgen at all so the only way I could fix it would be reverting but I don't wanna do that
19:08 RealBadAngel this can be used for different skies for realms
19:08 PilzAdam VanessaE, you can see the skybox by enabling noclip and fly
19:08 PilzAdam the server doesnt have to send blocks for that :-)
19:08 VanessaE ?
19:09 sapier don't take PilzAdam too serious he knows he's talking crap right now ;-P
19:09 RealBadAngel also i think it could be possible to blend skybox textures to have clouds at day, stars at night
19:09 RealBadAngel PilzAdam, and the direction can be defined by a vector, it doesnt have to spin in the circle
19:10 RealBadAngel v3f(0,.0025,0) here i have defined only speed around Y axis
19:17 Megaf_ I don't get it, what does 1132 and 1134 have to do with mapgen?
19:17 sapier 1132 doesn't have to do anything with mapgen
19:17 Megaf_ I think server is just missing something
19:18 sapier the only thing changes to as of working state is mapgen
19:18 sapier and settings
19:18 Megaf_ so could be just a simple thing, let me check
19:18 sapier could be but those changes aren't simple
19:19 sapier and imho the settings changes are wrong and need fixing
19:20 sapier but that's a consistency issue nothing that'd explain a hang
19:29 Megaf_ sapier: well, theres only one way to know, fixing them
19:29 Megaf_ perhaps that should be priority by now
19:30 sapier lets give hmmmm some time to find it
19:31 Megaf_ sapier: I pay you a beer or a pizza
19:31 Megaf_ will that help you?
19:33 sapier nope I don't have any intention to learn about mapgen while I haven't finished server clenups

23:09 hmmmm what is this i heard about mapgen not generating
23:10 VanessaE no
23:10 hmmmm it got the works on my machine seal of approval
23:10 VanessaE emergethread is not loading *anything*
23:10 VanessaE including old maps.
23:10 hmmmm interesting
23:11 VanessaE but chat and commands work.  roll back to 458045d49f and it's fine.
23:11 hmmmm well
23:11 hmmmm i know what has the potential to cause that
23:12 hmmmm does it say "EmergeManager: using 0 threads" ? or something
23:12 hmmmm in the infostream
23:12 VanessaE never checked.
23:12 VanessaE hold a few mins.
23:12 hmmmm nevermind, that's logically impossible to happen
23:13 hmmmm hmm let me read more about what occured over the course of the day
23:13 * VanessaE waits for the "oh shit...I did THAT?" moment.......
23:15 VanessaE 18:15:44: INFO[main]: EmergeManager: using 1 threads
23:16 hmmmm alright
23:16 hmmmm so penguindad, megaf, and you are having this problem
23:16 hmmmm is anybody else?
23:16 VanessaE and Soko, and Taoki
23:16 hmmmm first we need to figure out what you all have in common
23:17 VanessaE afaict, the only thing we all have in common is we all tried to use commits newer than 458045d49f, but we've all tried with both brand new maps and older, well-worn worlds.
23:18 hmmmm there must be some setting
23:18 * VanessaE looks in her (level-4) debug.txt ...
23:18 hmmmm wild guess but
23:18 hmmmm do you have emergequeue_limit_* specified in your settings.conf?
23:18 sapier sokomine has problems too
23:18 sapier I haven't tried yet
23:18 VanessaE nope.
23:18 VanessaE I do not.
23:18 hmmmm hm ah i do
23:18 hmmmm let's see if this happens if I don't
23:19 VanessaE also:  this affects singleplayer as well as separate server/client setups
23:19 hmmmm yup that's the problem
23:19 hmmmm okay
23:19 hmmmm so the NoEx functions don't seem to work or something...?
23:19 hmmmm hmm
23:19 hmmmm I see no reason why it shouldn't
23:20 sapier you mean "try" functions ;-)
23:20 VanessaE ok
23:20 hmmmm i'm going to change them to NoEx for consistency
23:20 sapier thanks :-)
23:21 sapier I've got same issue with latest git
23:24 hmmmm alright i don't get it
23:25 hmmmm the try* versions seem to be returning true even after getting into an exception
23:25 hmmmm is that code incorrect or something?
23:26 hmmmm anyway I know how I'm going to fix it, I'm going to make the no-exception versions the base variants, and instead the exception versions will be wrappers around get*NoEx
23:26 SpeedProg joined #minetest-dev
23:26 sapier at least for bool you catch it in non try version too
23:27 hmmmm no I don't do that
23:27 hmmmm that's celeron's original code
23:27 hmmmm see I wanted to modify the least amount possible
23:27 hmmmm exceptions were a horrible design decision for settings.. it really makes things more awkward to use than it should, and other things impossible
23:28 sapier true the whole "use exceptions as return code" is bad
23:28 hmmmm so sapier, do *you* see anything wrong with the code?
23:28 sapier https://github.com/minetest/minetest/commi​t/a439343844cf821e4922e23f1638b92e2cfb14ac L 591 seems to change getBool behaviour to me
23:30 hmmmm no that doesn't change getBool
23:30 hmmmm that piece of code at 591 is in getStruct
23:31 sapier argh that's just a crazy diff artefact
23:32 hmmmm honestly
23:32 hmmmm i'd fix this right now but
23:32 hmmmm i am too tired
23:32 hmmmm i'm running on 4 hours 30 minutes of sleep
23:32 hmmmm first thing when i wake up though i promise
23:33 sapier it's dev branch so not a big problem ;-) ... you shouldn't commit things with that less sleep. At least I do make a lot of silly mistakes in that condition ;-)
23:33 hmmmm but
23:34 VanessaE honestly, hmmmm .... mind if I make a suggestion?
23:34 hmmmm if somebody can figure out what's wrong with the approach i tried taking with the no exception variants please tell me why
23:34 hmmmm i'm genuinely interested why that doesn't work
23:34 sapier not telling this is a silly mistake in worst case your changes trigger a bug beeing in there before
23:34 VanessaE don't commit just before you head off for bed..... it makes stuff like this a lot harder to fix...
23:34 hmmmm vanessae, i don't have all day to code things
23:35 hmmmm by the time i'm done with what i was coding up it's night
23:35 sapier well it'll be there a day later to commit too ;-)
23:36 sapier and mapgen is an area not modified every day so chance a rebase is necessary aren't that big
23:36 hmmmm well
23:36 sapier but it's still dev branch and not stable so occassional breakage isn't world devastating
23:37 hmmmm if you want it to work for the moment, set emergequeue_limit_generate and emergequeue_limit_diskonly both to 10 or something in the config
23:37 hmmmm but seriously later
23:37 hmmmm i'm out
23:37 sapier good night
23:39 VanessaE well... I just meant (noting that it's too late for him to see this) that said commits should perhaps wait till the next day before pushing is all.
23:42 sapier hmmmm it's not your idea beeing wrong but minetest never checking for errors
