Fixes a bug where the old list ring remained when a new formspec
was displayed over the old one. This created the list-ring of the new formspec
to be partly ignored.
Thanks to @VanessaE to report the bug, and @DonBatman to produce the code that
exposed it.
This might break some mods, but it is important for all uses of the param2 to
be documented.
This doesn't need a serialisation version or network protocol version change,
as old clients will still work on new servers, and it is bearable to have
new clients getting non rotated plants on old servers.
It returns the index used in mg->biomemap for a given biome name.
The biomemap is useless without this unless you re-register all existing biomes,
which could cause problems for anyone else trying to use biomemap.
With this, you can quickly create a lookup table of ids and names.
Get facedir by using lowest 5 bits of param2 and limiting to 23
More robust, frees up higher param2 bits for other uses
Change lookup table and table index to u8
1. Check for entity addition success in spawn_item implementation
2. Check for success in item_drop callback, so that the player
doesn't lose the item if they are outside bounds and try to drop it.
3. When existing player joins game, check that their position is inside
map bounds. If not, set their position to the return value of findSpawnPos().
4. Make findSpawnPos() respect the border
2 fixes a lua crash if a player drops an item outside map bounds.
3 fixes an assertion crash if a player leaves when being outside map bounds,
and then rejoins.
Because the count is serialized as u16, this would cause overflow.
If minetest later deserialized a mapblock with an incorrect
static object count, it would be unable to find the NameIdMapping
(which comes after the StaticObjectList) and abort with an error
such as "Invalid block data in database: unsupported NameIdMapping
version" (issue #2610).
Sidelen larger than 16 is essential for low density decorations
With sidelen > 16 chunksize may not be divisable by sidelen if
chunksize is changed, in this situation setting sidelen = chunksize
is desirable and should not create error messages.
Change a remaining assert(0) call to FATAL_ERROR(msg).
There was a regression since commit
ced6d20295a8263757d57c02a07ffcb66688a163 "For usages of assert() that are meant to persist in Release builds (when NDEBUG is defined), replace those usages with persistent alternatives"
where when an "uncatched" exception is thrown inside a "side thread",
the program doesn't abort anymore.
This led to the problem @netinetwalker experienced where the emergethread
got an unhandled exception for loading a mapblock while redis was loading,
(see #3196) and then jmped outside its loop to work down its queue.
This resulted in the server not doing any emerges anymore.
