Fixes: #3913#3915
~~You can reproduce the crash by placing a fish bucket on top snow above an unknown node.
I also noticed that the code always uses pointed_thing.above so I fixed that and also added a function to mcl_utils to figure out where a node should be placed (either above or below). Looks like the rest of the code could also use improvement but at least it does not crash now.~~
Cora fixed a bunch of related crashes in Mineclona so I am replacing my commit and cherry picking all her commits here.
https://codeberg.org/mineclonia/mineclonia/pulls/549
Here is the list of fixes from that PR:
- Crash when placing snow layer on unknown nodes
- Crash when snow layers on unknown nodes are flooded
- Crash when placing fishbucket on snow on top of unknown nodes
- Crash when placing chorus flower and stem on unknown
- Crash when placing mob spawners on unknown
- The fishbucket on place to actually replace buildable_to

This texture has the following poem written by me, cora, encoded in its
pixeldata. I the author hereby release both the texture file and the
poem as cc0.
Additionally I explicitly consent with its inclusion into MineClone2,
MineClone5 and Mineclonia as well as any other minetest game for this
day and all the days to come.
Shall though betray me with a texture, mate
I'll smile at though just like a summer's day
The raindrop particles - no laggy state
But spring is coming, really, soon it's may
As If the seasons meant a damn to us
They do not exist in mineclone at all
unreal water flow, iron never rusts
but copper does in summer and in fall
But what this literally is about
because this damn thing is really silly
you see somehow they had to say it loud
I would bring that quote with painting lilys
but plagerism everywhere you see
so this will just be good enough for me
A user claimed that this texture was a texture from Minecraft 1.8.9 –
see <https://git.minetest.land/MineClone2/MineClone2/issues/2099> for
further details. I have not verified that but I noticed that in commit
152e552458 the file was replaced with a
file containing the exact same pixels.
A visual inspection confirms that the file contains noise, so it is not
clear if it is even copyrightable. However, to ensure that it could not
be identical to a file from Minecraft, To get noise of the same quality,
I have shuffled all its pixels with the following POSIX sh shell script:
LANG=C
PREFIX=mcl_end_crystal_beam
convert $PREFIX.png $PREFIX.pnm
<$PREFIX.pnm >$PREFIX.plainpnm pnmtoplainpnm
<$PREFIX.plainpnm >$PREFIX.seed tr '1234567890 ' ' 1356902468'
(
<$PREFIX.plainpnm head -n+3
<$PREFIX.plainpnm tail -n+4 \
|tr ' ' '\n' \
|shuf --random-source $PREFIX.seed
) >$PREFIX.shuffled.plainpnm
I then opened mcl_end_crystal_beam.shuffled.plainpnm using GIMP,
converted the color black to tranparency and saved the image as a
paletted PNG (which yields a smaller filesize than a grayscale PNG).
This fixes:
