02:05 VanessaE      21:05:21: ERROR[main]: Invalid block data in database (0,-1933,-1) (SerializationError): unsupported NameIdMapping version
02:06 VanessaE      someone managed to get to position = (40,-309125,-50)
02:07 VanessaE      looks like they got there by teleporting, due to a bug in a mod
02:07 VanessaE      why are we allowing people to teleport out of the official edges of the map?
02:08 VanessaE      shouldn't that be clamped to +/- 31k?
02:09 VanessaE      unless the value is 1/10 of the player's actual position?
02:11 VanessaE      meh, disregard the stuff about the player position.  the player says he used a mod in a way not consistent with its normal use, but the above is the error that's thrown, which is clearly not from the mod :-)
02:18 VanessaE      here's the rest of the error text associated with the crash:  http://pastebin.ubuntu.com/6419048/
02:18 VanessaE      might be an incorrect use of vmanip in ShadowNinja's bedrock mod, or Sokomine's travelnet mod, I can't tell which
02:27 kahrl         yeah, player coordinates are multiplied by BS so that player was most likely at (4,-30912.5,-5)
02:27 VanessaE      right
02:27 VanessaE      ok,
02:27 kahrl         which is where that corrupted block is
02:27 VanessaE      I think the vmanip corrupted my map
02:28 kahrl         I don't think they should be able to
02:28 VanessaE      https://github.com/ShadowNinja/minetest_bedrock
02:28 VanessaE      notice it generates at -30912 by default.
02:28 kahrl         maybe there's some bug with blitting back when near the world edge
02:29 VanessaE      I disabled the bedrock mod but that wasn't enough to stop the crash.  Now I'm doing /clearobjects because it basically re-processes the whole map (so I'm hoping it'll wipe out the corrupt block)
02:30 kahrl         well, if the server can't load the block it probably won't be able to save over it
02:30 VanessaE      actually, I've done this once before - there was a block near the spawn that refused to save.  /clearobjects fixed it.
02:30 VanessaE      (a month or so ago)
02:31 VanessaE      if I disable aborting on corrupt blocks, visit the corrupt area, and then restart with the corrupt-checking re-enabled, will that fix it?
02:31 kahrl         it could
02:31 VanessaE      (at this point it doesn't matter if anything gets lost down there)
02:32 VanessaE      obviously I have to add a torch or something, to force it to save
02:32 kahrl         if we had libmtmap you could write a quick program to delete the block...
02:32 VanessaE      yeah
02:33 kahrl         DELETE FROM blocks WHERE pos = -24694784
02:34 kahrl         ^ type that into a sqlite console, no warranties ;)
02:35 VanessaE      ehm...  I shy away from such commands... :)
02:37 VanessaE      in singleplayer, ServerEnv: Trying to store id=2 statically but block (-2,-1933,-1) already contains 2798 objects. Forcing delete.
02:37 kahrl         whoa...
02:37 VanessaE      um, there should be zero objects in that block, that's a brand new map
02:37 VanessaE      the only thing that could have generated down there is bedrock.
02:37 VanessaE      and you'll note it's at -1933 again
02:38 kahrl         well that reminds me of the rat infestastion at the bottom of a 31000 node deep hole on gameboom (I think)
02:38 VanessaE      haha
02:38 VanessaE      impossible in this case - it's a cave with no path to the surface.  I simply teleported down to -30900 and looked around a bit for a cave at the map edge
02:43 VanessaE      I exited and started that singleplayer map again.... suspiciously large amount of objects detected: 2798 in (-2,-1933,-1); removing all of them.
02:44 VanessaE      and then this when I exited that map:  21:44:17: ERROR[main]: ServerEnv: Trying to store id=2 statically but block (-2,-1933,-1) already contains 1256 objects. Forcing delete.
02:47 VanessaE      ok, /clearobjects was not enough to fix it.
02:49 ShadowNinja   VanessaE: "cp map.sqlite mapbackup.sqlite && echo 'DELETE FROM blocks WHERE pos = -24694784;\n.quit\n' | sqlite3 map.sqlite"
02:51 VanessaE      is there a graceful way to just delete everything below a given point?
02:52 ShadowNinja   VanessaE: Not a easy way, as they are stored as hashed ZYX I beleive...
02:56 ShadowNinja   u64 hashedpos = ((u64)pos.Z << 32) & ((u64)pos.Y << 16) & ((u64)pos.X << 0) <-- Something like that.
02:59 VanessaE      oy.
02:59 VanessaE      syntactically I can read that and understand what it means, but somehow I just can't wrap my mind around the whole mess :)
03:03 ShadowNinja   VanessaE: Maybe this answers your question: Z is stored in the second 16 bits, Y in the third 16 bits, and X in the last 16 bits of a 64 bit number(First 16 aren't used). Otherwise I don't know what you mean.
03:04 ShadowNinja   Of course I'm not absolutely sure about that, and it's actually a signed number.
03:04 VanessaE      ShadowNinja: I mean wrapping my mind around the entire idea of fiddling with the map.  Whenever I try to do anything remotely complex, I invariably screw up, and with a minetest map, it's basically impossible to be 100% sure I don't.
03:04 VanessaE      I can read that code just fine.
03:05 ShadowNinja   VanessaE: Backups! :-)
03:05 VanessaE      I keep backups, and in fact just restored the broken map from this morning's.
03:07 VanessaE      oh real nice.  22:07:05: INFO[ServerThread]: WARNING: Block failed to save (-21, -2, -27) SQL logic error or missing database
03:09 ShadowNinja   Oh, BTW I will be away for the weekend.
03:10 ShadowNinja   Anyone to agree to #995(pcall_errfunc)?
03:11 ShadowNinja   kahrl: ^?
03:12 kahrl         did you fix the thing that sapier was talking about?
03:12 ShadowNinja   kahrl: Yes.
03:13 VanessaE      oh, that failed-to-save was just a permission error.  forgot to reset ownership after restoring the file.
03:13 ShadowNinja   It's been running on Vanessa's servers for the past week or so and has helped find 3+ bugs that would have otherwise been untraceable.
03:16 VanessaE      so about the map corruption - what will be done to prevent this in the future?  it's not at all uncommon for people to aim for the bottom of the world jut to set up a shop or something at the end of a travelnet/teleporter
03:16 VanessaE      just*
03:21 kahrl         ShadowNinja: https://github.com/ShadowNinja/minetest/commit/a87d9a6000807851034ab61597f04cac514d0a92#diff-fa972960897c9e4bc3a67e650231e6a8R50
03:21 kahrl         since read_item doesn't pop the value from the stack, the lua_pop should be moved outside the "else"
03:22 ShadowNinja   kahrl: Ok, I'l check that...
03:23 kahrl         same thing in a couple other places too
03:26 kahrl         VanessaE: dunno, since I have no idea what could have caused that
03:29 ShadowNinja   kahrl: Fixed.
03:30 mrtux         Seems to be some error in compilation here: https://pastee.org/53xh9
03:30 mrtux         undefined reference to `png_set_gray_1_2_4_to_8'
03:34 mrtux         it's probably just arch being the annoying distro it is at times
03:38 kahrl         ShadowNinja: looks good now
03:39 ShadowNinja   kahrl: Ok, should I get another to agree?
03:40 kahrl         technically you don't need to... if you're unsure then wait for hmnmm to look at it too
04:23 VanessaE      another bug that cropped up after kaeza's fix for the player.lua "anim" crash:
04:23 VanessaE      http://digitalaudioconcepts.com/vanessa/hobbies/minetest/screenshots/Screenshot%20-%2011142013%20-%2011:21:32%20PM.png
04:24 VanessaE      that is the "green thing" 2d player sprite being wrapped around the current 3d player model.
04:24 VanessaE      the player seen here is facing to the right, his back is to the wall
04:28 VanessaE      I restarted the server, signed out and back in, the player's skin is back to normal
04:28 VanessaE      almost seems like an uninitialized variable somewhere.
13:08 artur99       hi
13:08 artur99       is anybody online?
13:08 artur99       :)
14:14 Exio4         are there news about the 'android port'?
14:14 Exio4         or just the "code coming soon"
16:45 ShadowNinja   PilzAdam: Can you review pcall_errfunc?
17:06 artur99       a minetest server runs on a server with 128 mb ram?
17:21 iqualfragile  artur99: apparently it does
17:22 iqualfragile  seems a bit too litle in my oppinion
17:57 iqualfragile  PilzAdam: https://github.com/minetest/minetest/pull/1000
18:01 artur99       what print stacks command does?
18:44 ShadowNinja   sfan5: Can you take a look at pcall_errfunc?
18:45 sfan5         link?
18:45 ShadowNinja   sfan5: https://github.com/minetest/minetest/pull/995/files
19:07 artur99       what Print Stacks does
19:08 artur99       ?
19:08 sfan5         artur99: debugging use
19:09 artur99       in debug.txt
19:09 artur99       ?
19:12 sfan5         no
19:12 sfan5         ShadowNinja: as long as it works it seems fine
19:12 sfan5         s/seems/is/
19:12 ShadowNinja   Ok, it's good to merge then...
20:28 VanessaE      can someone please look into this:
20:28 VanessaE      http://digitalaudioconcepts.com/vanessa/hobbies/minetest/screenshots/Screenshot%20-%2011142013%20-%2011:21:32%20PM.png
20:28 VanessaE      this has been happening since the player.lua rewrite.
20:30 kaeza         huh
20:34 VanessaE      it's random, the same player might get the regular sam (well, I use Sam II) skin on their next sign-on
20:34 VanessaE      then someone else might get that ^^^^^^
20:44 iqualfragile  looks like the old 2d player texture would be used
20:47 VanessaE      yeah
23:05 VanessaE      um, guys....this can't be good:  http://pastebin.ubuntu.com/6423663/
23:07 VanessaE      (that was my creative server, to be specific)
23:09 Warr1024      11GB?  Am I reading that right?
23:10 VanessaE      yes
23:12 VanessaE      I and one other person had just signed on, noticed the map didn't want to load right away.  suddenly load, suddenly the PC's acting like it's thrashing about in swap (even though I don't have any), then the OOM killer aimed and fired at that server process.
23:14 VanessaE      (and scored a direct hit ;) )
23:14 Warr1024      could be worse if it had missed.
23:42 RealBadAngel_ hi
23:44 RealBadAngel  i would like to push reworked shaders part (solids)
23:44 RealBadAngel  without water atm
23:46 RealBadAngel  can i ask for some pros or cons?
23:49 RealBadAngel  code is rather well tested, since a few weeks
23:50 RealBadAngel  stable enough imho to merge
23:50 VanessaE      As long as they look better and run faster than the existing ones, and don't break anything we already had, seems okay to me.
23:50 VanessaE      what's changed?
23:50 PilzAdam      RealBadAngel, you need to post at least a diff or a pull request
23:51 RealBadAngel  code is really polished. im polish for christ sake ;)
23:52 RealBadAngel  i am askin for devs if they do like what im doing
23:52 RealBadAngel  now im at the point i feel im ready wiht oclussion
23:53 RealBadAngel  at least aviable normal maps generators or plugins are givin same preview as i do get ingame
23:54 RealBadAngel  so i guess im on the right track
23:55 RealBadAngel  and for the record: check the spoilers: https://forum.minetest.net/viewtopic.php?id=7708
23:55 RealBadAngel  ive added self shadowing for surfaces
23:55 RealBadAngel  smoothed oclussion
23:56 RealBadAngel  shaders are reworked, at all
23:56 RealBadAngel  adding any new effect wont require new shader copy
23:57 RealBadAngel  i have limited shaders back to just 3 of them
23:57 RealBadAngel  no matter what effects are turned on
