my point was, that was at the time all europeans were sleeping, and because nobody reacted at all, probably ops are europeans |

sapier: 1167 seems like it should work, but I would do it slightly differently (about 2 lienes shorter and a bit simpler) |
| 20:49 |
ShadowNinja |
I'll test and tweak it. |
| 20:49 |
sapier |
even more short? :-) |
| 20:50 |
ShadowNinja |
sapier: Yes, keep the ++i in the for loop, remove the else clause, and use erase(i); |
| 20:50 |
|
grrk-bzzt joined #minetest-dev |

sapier |
I'm carefull with ++i i++ as this is one of the locations I know I make mistakes so test it good ;-) |
| 20:54 |
sapier |
I wonder if there's a way to catch those unaligned memory accesses without getting a issue for each occurence |
| 20:56 |
ShadowNinja |
sapier: Like so: http://ix.io/b3E |
| 20:58 |
ShadowNinja |
That goto was really odd. The loop would have removed any other players even without it. |
| 20:58 |
kahrl |
ShadowNinja, you can't do that |
| 20:58 |
sapier |
good question ... I just don't know :-) that's why I avoid iderators for doing things like that ... maybe someone knows if this is correct or not |
| 20:59 |
kahrl |
you'll use i after it has been destroyed |
| 20:59 |
ShadowNinja |
kahrl: Huh? Where? |
| 20:59 |
kahrl |
you have to say i = m_players.erase(i) and skip the ++i afterwards |
| 20:59 |
ShadowNinja |
kahrl: Ah, OK. |

that's the thing called "fun with iterators" ... I hate it ;-) |

+? |
| 21:08 |
kahrl |
what other threads are accessing m_luastack at the same time? |
| 21:09 |
sapier |
none |
| 21:09 |
sapier |
it's not allowed at all |
| 21:10 |
sapier |
if someone tries this is a bug |
| 21:11 |
sapier |
but this assertion doesn't tell about a concurrent acces but about a failed creation ... no idea how that's possible |
| 21:11 |
kahrl |
perhaps http://stackoverflow.com/questions/20858911/lua-open-returns-null-using-luajit? |
| 21:12 |
kahrl |
or something similar |
| 21:12 |
kahrl |
out of memory? |
| 21:13 |
sapier |
yes but It's long time I've seen a out of memory in a non resource leak scenario |
| 21:13 |
ShadowNinja |
m_luastack = luaL_newstate();\nassert(m_luastack); |
| 21:13 |
sapier |
the assertion is correct there, so why do we fail to create a lua stack is the real question |
| 21:14 |
ShadowNinja |
Returns the new state, or NULL if there is a memory allocation error. |
| 21:15 |
sapier |
memory allocation errory should be as rare as water in desert nowadays ;) |
| 21:15 |
ShadowNinja |
That happens consistently though. |
| 21:15 |
sapier |
we're not allocating GB of memory but just a few KB |
| 21:15 |
sapier |
unless there's a bug in there ... is this limited to a special luajit version? |

is there a chance we can drop luaJIT support? that piece of code always causes bugs |

no. fucking. way. |
| 21:20 |
ShadowNinja |
sapier: And you don't know that it's LuaJIT-only. |
| 21:21 |
sapier |
I haven't heared about any similar bug in lua ;-) ... but I was kidding anyway ... yet luajit causes a lot of trouble |
| 21:22 |
sapier |
obviously is way from beeing as marture as lua is |
| 21:25 |
sapier |
does @arch mean he's on arch linux? |
| 21:27 |
ShadowNinja |
sapier: Yep. |
| 21:28 |
ShadowNinja |
non-JIT Lua does work. |
| 21:28 |
sapier |
in this case I'll not even try to find this one without way more information ... in 9/10 cases it's related to some of archs bleeding edge versions |
| 21:30 |

I don't know why people always think "new is better" |

https://github.com/minetest/minetest/issues/1141 -- Fix warnings shown by clang by sapier |

because -Wall warns about things like C99 usage too |
| 22:32 |
sapier |
you don't see the real errors in hundreds of bogus ones ... and we can't fix them |
| 22:32 |

sapier: But SQLite3 is a C99 library. |

sapier: No, I'll fix it... |

Oh, irrlichttypes uses a #ifdef _MSC_VER too. |

(MSVC doesn't have stdint.h?!) |
| 22:53 |
sapier |
maybe in recent versions but not the older ones ... don't ask me as of what version ;-) |
| 22:53 |
sapier |
but I guess even there it's called something like "ms_special_int.h" |
| 22:55 |

Hmmm, getBlockAsInteger returns a long long, aka s64, shouldn't it be u64? |
| 22:56 |
sapier |
if it's called AsInteger I'd not think so |
| 22:56 |
sapier |
but of course that name could be wrong too I don't know |

I've had bad experiences with signed numbers and binary operators... |
| 23:04 |
sapier |
you could ask celeron I guess this code is written by him |
| 23:05 |
ShadowNinja |
Possibly, or whoever added the alternative backends. |
| 23:05 |
sapier |
oh it's not in engine but database backends? |
| 23:06 |
sapier |
the backends aren't by celeron |
| 23:06 |
ShadowNinja |
Anyway, it's 64 bits and the position will only take up 46 bits of that, so it can't overflow to signed. |

sapier: All long longs removed, with the exception of SQLite3 and things in #ifdef _MSC_VER: http://ix.io/b3I |
| 23:08 |
sapier |
you could try to use different flags for subdirs? |
| 23:08 |
ShadowNinja |
sapier: SQLite3 should be compiled as C99. |
| 23:09 |
ShadowNinja |
The included SQLite3 is almost never used and far out of date though. |
| 23:10 |
sapier |
time to update but that's something different |

ok lets check and try to merge it till end of coming weekend |
| 23:14 |
VanessaE |
yes, get that damn thing merged already |
| 23:20 |
RealBadAngel |
it would be good if folks will try this |
| 23:36 |
ShadowNinja |
sapier: Fine if I push those long long fixes? |
| 23:36 |
sapier |
yes ... hope it's really all |
| 23:36 |
sapier |
it's useless if it isn't :-( |

RealBadAngel: I believe it is simply too non-generic. Just about the only similar mod is mesecons, and even mesecons might not use it because of issues with auto-rotation and the like. |
| 23:44 |
ShadowNinja |
s/similar mod/mad that could use it/ |
| 23:59 |
RealBadAngel |
even if mesecons will be the only mod that will use it, still worthy imho |
| 23:59 |
RealBadAngel |
should be lotsa faster than a mod |
