celeron55: does inchra-stats.minetest.net redirect to inchra.net via CNAME? |
| 18:17 |

dig inchra-stats.minetest.net: "inchra-stats.minetest.net. 600 IN CNAME stats.inchra.net." |

does it take less time for lua to call a local function then a global? |
| 20:07 |
VanessaE |
in theory locals are faster than globals for just about anything, but if it's just a single call that you do every so often, the difference is too small to notice |
| 20:08 |
T4im |
rule of thumb: if you use it twice, put it into a local |
| 20:08 |
VanessaE |
(versus say thousands of such calls over a short period of time - you might notice it then, depending on what the call does to begin with |
| 20:08 |
VanessaE |
yep, that's about right |
| 20:09 |
VanessaE |
the more important thing is you don't want to pollute the global sapce |
| 20:09 |
VanessaE |
space* |
| 20:09 |
rubenwardy |
> twice |
| 20:12 |
red1 |
Does "local myfunction = global_function" make call it faster or slower? |
| 20:12 |
VanessaE |
slower. |
| 20:12 |
VanessaE |
you're forcing the interpreter to take an extra step to get to the actual function |
| 20:12 |
T4im |
calling myfunction afterwards will be faster, since the local variable is accessable by index, but if you're using it only once afterwards, then what VanessaE just said |
| 20:13 |
VanessaE |
now, if you *copy* the function entirely, then it'll probably be faster |
| 20:13 |
red1 |
no I'm using it many times |
| 20:13 |
T4im |
you see it often in lua that the document starts with something like: local minetest = minetest |
| 20:13 |
rubenwardy |
Do some bench marks and find out |
| 20:13 |
rubenwardy |
Shall I? |
| 20:14 |
red1 |
Yes please |
| 20:14 |
T4im |
make sure not to use jit, or the results will be unusable |
| 20:14 |
T4im |
jit will simply optimize each time you run it |
| 20:15 |
VanessaE |
the irony of t4im's statement about jit is that you generally never want to go *without* it ;) |
| 20:15 |
T4im |
indeed :D |
| 20:15 |
VanessaE |
(except for benchmarks of this type) |

For 100,000,000 incrementations, with local: 1.09 seconds. With global: 5.10 seconds. |
| 20:18 |
rubenwardy |
local test = 0; for i = 1, 100000000 do test = test + 1 end |
| 20:18 |
rubenwardy |
with local not included for the global test |
| 20:18 |
rubenwardy |
so it's five times slower |
| 20:19 |
VanessaE |
sounds about right |
| 20:19 |
rubenwardy |
however, the time to look up may be neglible compared to the time to switch to the function |
| 20:19 |
T4im |
same factor as "Steve" http://lua-users.org/wiki/OptimisingUsingLocalVariables |
| 20:20 |
rubenwardy |
this is with plain lua |
| 20:21 |
rubenwardy |
for function calling 20,000,000 times, 0.81s for local, 1.21 for global |
| 20:21 |
rubenwardy |
so ~math calc 1.21/0.81 |
| 20:21 |
rubenwardy |
~math calc 1.21/0.81 |
| 20:21 |
ShadowBot |
rubenwardy: 1.493827160493827 |
| 20:21 |
rubenwardy |
1.5 times slower |

exio4 |
the global environment is dynamic and the local environment can be deduced statically |
| 20:26 |
exio4 |
nothing surprising there |
| 20:27 |
rubenwardy |
It's a table look up |

game 672 looks nice; engine needs to have some way to not hide the particles that are under the water when looking from above. |
| 23:38 |
blert2112 |
building latest I get "‘FATAL_ERROR_IF’ was not declared in this scope |
| 23:38 |
blert2112 |
". Any clues for me please? |
| 23:38 |
VanessaE |
no idea, blert2112. pastebin the full build log |
| 23:39 |
VanessaE |
make a new issue on minetest github repo if you can't solve it |
| 23:51 |
blert2112 |
I will continue banging on it for a while and come back if I can't solve it. |
