There's a mod problem here. Also, the line number in the first post doesn't match mesecons which implies that it's out of date, so I suggest updating the mod pack

Search for "swap_node" in all your mods and make sure none are assigning it
Maybe paste the output here.

You can do this by running this command: grep -rn "swap_node" ~/.minetest/mods/

Re: swap_node - something changed?

Postby rubenwardy » Sat Mar 23, 2019 1:12 am

I meant that it's weird that swap_node is a table, it should be a function. So I suspect that something is setting to it, like:

Code: Select all
minetest.swap_node = something


Seeing the results of grep could confirm it

ah, ok -

but funny also,
that day before this happened I was only on 2nd machine, and measuring lua memory consumption, and only set 3 more mods false at this server before went sleep ... so there was no code change explaining that this failure started in that night,

so if my mistake, but even that I did AFTER first crash, need to search for wrong "swap_node = {}" ?

don't need to send grep result,
could read it myself, and also remember now what I had to search for
found
in ./mods/moretrees/cocos_palm
Code: Select all
minetest.swap_node = {} -- until now, attempt to index a nil value, line 99 to 118

but this code I did IN after the failure with "swap_node" happened first time, as referring to unknown global ,...

ah, moment ...

running so far
tested
* adjustable_blinkyplant = no crash
* can use doors right_click = no crash
need to find cocos tree, as here it started all

thanks for the hint ! with grep, via search monkey i didn't find it

this was the reason, as crashed before
Code: Select all
elseif not moretrees.coconuts_regrow then
      -- Regrowing has been turned off. Make coconust grow instantly
      minetest.swap_node(pos, {name="moretrees:coconut_3"})
      return

and MADE me using the code above to get around here as crashed before.

Remove that line completely, it's not correct at all.

The error about being unable to index nil is due to the position or node being nil, more likely the former

That was the one I deleted in the morning, after I remember one missing, but you gave better search tool, and it should not have been in the grep result.
After this removing the crash happened with the last post about in moretrees/grow_jungletree when gamer Bron came in, didn't happen jet again, but sure I didn't change anything until now as no glue.

extend the search to
* /usr/local/share/minetest/games/minimal/mods/default/init.lua:1423:function swap_node(pos,name)
* /usr/local/share/minetest/games/minetest_game/mods/default/furnace.lua:90:local function swap_node(pos, name)

grep -rn "swap_node" ~/.minetest/worlds/CelinesWildesThailand/worldmods/ - nothing
