Without this fix, the banner pattern preview generation does not mask
the banner pattern, so the alpha channel of the banner pattern is not
taken into account. This lead to preview banners with color gradients
showing up as a solid color banner and opaque pixel artifacts for the
bottom triangle pattern.
When a player joins and immediately leaves the game before a function is
called by minetest.after() in mods/PLAYER/wieldview/init.lua, it gets an
invalidated player object. This results in the player methods returning
nil (since Minetest 5.2); perhaps surprisingly, the player is not nil.
Not checking that the result of player:get_pos() is not nil could lead
to a server crash if a client crashed when joining. It has been reported
that a syntax error in a client side mod was enough to trigger that.
The “getwrittenbook” command gives a player that has the “debug” privilege a book
with a configurable amount of characters. This was added as a debug aid, to help
reproducing situations in which items with lots of metadata trigger issues like
heavy lag or server crashes.
Some items, like shulkers or books, can have so much metadata that the
corresponding item entity can not be serialized by the Minetest engine.
Without this patch, dropping such an item and then moving away crashes
Minetest, as it can not serialize the entity with serializeString16()
when unloading a map block.
The patch resets the overlong metadata of non-serializable item entities.
This avoids a crash and makes it possible to retrieve a “sanitized” item
without metadata when the mapblock containing the item entity is reloaded.
Originally sfan5 guessed the maximum possible item entity serialization size
that would not lead to a crash as 65530 bytes, but anon5 calculated it to be
actually 65487 bytes. This has been experimentally verified by erlehmann.
In Minecraft Java Edition, when the map generator generates a spawner,
it can generates a pig spawner instead of the spawner it should create.
That behaviour is very rare, but has never been removed from Minecraft.
This patch changes 1 in 1000 spawners in a mineshaft to be a pig spawner
instead of a cave spider spawner.
Several mods set or unset the visibility of a HUD bar way too often (e.g.
in a globalstep handler), causing the server to send a lot of superfluous
HUDCHANGE packets to each client. Returning from hb.hide_hudbar() early
if HUD bar visibility would not change prevents sending these packets.
Before this change, about 10 to 30 FOV packets were sent from the server
to each connected client each second. This patch only sends FOV packets
when the FOV actually needs to be changed, i.e. when the player starts
or stops sprinting.
Commit 819dbc6224c3b96ad4094cccf3d9150f3ef61d45 of MineClone2 introduced
an LBM that removed Ender chest formspecs stored in the node meta. That
change makes Ender chests that were loaded in MineClone2 versions past
that commit not show the Ender chest inventory form on right-click.
This patch makes those broken Ender chests work by introducing an LBM
that writes the formspec to the node meta for Ender chest nodes once.
Since the LBM name is suffixed with a hash of the Ender chest formspec,
changes to the Ender chest formspec (even removing it entirely) should
not require manual adjustment of the LBM code.
It was possible to duplicate snow layers by placing them and then mining
them using a tool enchanted with silk touch. This commit fixes the “snow
dupe” by reducing the amount of snow layers dropped in this case by one.
As beetroot often did not drop seeds, players could end up with no seeds when
trying to farm beetroot. This patch guarantees that at least one beetroot seed
is dropped when harvesting beetroot.
Digging unknown nodes crashes the Clamity Minetest server, which
runs modified Minetest: https://github.com/ClamityAnarchy/minetest
Crashes did occur with commit d5434bf008 of that Minetest version.
This commit makes unknown nodes explicitly not harvestable.
With the introduction of the mcl_jukebox API, all music record items
were given new names. Old music record items were aliased, but never
worked with the jukebox. Apparently no one tested existing records.
By explicitly looking up the item name in minetest.registered_aliases,
the jukebox accepts old records, plays them, and gives out new records.
This removes the need to include _mcl_autogroup as a dependency for
mcl_inventory (which should be avoided) and decreases the likelihood
that the code used for populating item tables is executed before all
other mods are loaded.
