This patch shifts mcl_farming nodes that represent a stem 1/16 nodes
downwards. It also replaces the plantlike drawtype of mcl_farming nodes
that represent an unconnected stem (x) with a nodebox drawtype that
looks like a plus (+), as Minetest has no option to rotate nodeboxes.
The goal is to remove the gap between plants and farming soil with a
node height of 15/16.
This patch affects melon stem and pumpkin stem nodes.
This patch replaces the plantlike drawtype of mcl_farming plant nodes
that are rendered like a grid (#) with a nodebox drawtype. The nodebox
looks like a plantlike grid shifted 1/16 nodes downwards. The goal is to
remove gaps between plants and farming soil with a node height of 15/16.
This patch affects beetroot, carrots, potatoes, and wheat nodes.
This patch adds the debug command “/generate_farming_plant_rows”. The
command generates rows of plants and stems per plant type near a player.
A farming soil or glass node is placed below each node, so players can
find and examine possible gaps between a plant node and a node below.
This patch adds a new test structure to the “/spawnstruct” command which
can be spawned with this command: /spawnstruct test_structure_tnt
The structure was added to reduce manual work when examining or
verifying TNT explosion results after changes to TNT drop rate.
The code for shearing a pumpkin used minetest.swap_node() to replace a
faceless pumpkin with a carved pumpkin. This did not trigger the node
callbacks of the carved pumpkin, which meant that shearing a pumpkin
would not check for the snow golem or iron golem spawn conditions.
This patch replaces minetest.swap_node() in the code for shearing a
pumpkin with minetest.set_node(), which does trigger the callbacks;
therefore snow and iron golems can now spawn as a pumpkin is carved.
While testing the previous commit, it became clear that gourd stems do
not disconnect properly if the gourd disappears while not being dug. A
simple method to create illegal curved stems was to explode the gourd.
This patch changes gourds so that the stem curves back after a gourd is
destroyed, regardless of reason. This hopefully makes curved stems that
are not connected to matching gourds a relict of the past.
Carved pumpkins can end up being connected to a stem – either if they
were grown in a previous version of MineClone2 or Mineclonia, or if a
player carves them before harvesting them. This patch makes sure that
stems turn into unconnected stems after such a carved pumpkin is dug.
As map generation and growing mechanics have been changed to generate
uncarved pumpkins instead of carved, requiring players to shear every
pumpkin before trading it with villagers seems like useless busywork.
Shearing an uncarved pumpkin turns it into a carved pumpkin and drops
four pumpkin seeds. As map generation and growing mechanics have been
changed to generate uncarved pumpkins instead of carved, preserving a
recipe to get pumpkin pie from carved pumpkins enabled players to get
both seeds and pumpkin pie from grown pumpkins, which was unintended.
Shearing an uncarved pumpkin turns it into a carved pumpkin and drops
four pumpkin seeds. As map generation and growing mechanics have been
changed to generate uncarved pumpkins instead of carved, preserving a
recipe to get seeds from carved pumpkins enables players to get twice
the amount of seeds as intended. Because of this, the recipe must go.
The code for turning an uncarved pumpkin into a carved pumpkin using
the shears was using “above” instead of “pointed_thing.above” as the
location for its sound. This resulted in a warning being logged when
shears were being used on a pumpkin. This patch rectifies the issue.
Carved pumpkin has to be explicitly registered as a separate node, as
registering a carved pumpkin node happened as a side effect of invoking
mcl_farming:add_gourd() for the carved pumpkin.
The iron / snow golem spawning checks that trigger whenever a carved
pumpkin is placed had to be moved out of the mcl_farming:add_gourd()
invocation to preserve the existing behaviour.
Note that uncarved pumpkin must not be registered as a separate node,
as invoking mcl_farming:add_gourd() for a registered node name leads to
stems not updating when an adjacent node is manually placed or mined.
Redstone comparators have two modes, comparison mode & subtraction mode.
Before this patch, the functions to turn comparators on or off attempted
to swap nodes with comparators in the same mode, but failed to determine
the correct replacement node, if the existing node was not a comparator.
When a comparator in an on state (e.g. powered by a filled cauldron) was
flooded, the flooding dropped the comparator and replaced the comparator
node that was to be swapped out with air, which lead to a server crash.
This patch changes the functions that turn comparators on or off so they
only swap existing nodes with comparators in the same mode if the name
of the replacement node can be determined – i.e. if it is not nil.
This patch adds a new test structure to the “/spawnstruct” command which
can be spawned with this command: /spawnstruct test_structure_comparator
The structure was added to reduce manual work when examining or
verifying comparator behaviour after changes to comparator code.
Before this patch, when placing a fire above a node that would turn it
into eternal fire (e.g. Netherrack or Magma) the spawn_fire() function
would call itself infinitely via the on_construct() handler of eternal
fire – because the latter called spawn_fire() itself.
On an x86 machine, this caused a memory leak, hanging Minetest. On an
x86_64 machine though, Minetest crashed immediately, showing an error
message about a stack overflow.
Even the mitigated timers seem to have lead to slow
memory leaks. Once Minetest has used up all the RAM,
it will free some, then quickly use memory up again,
then repeat it ad nauseum, requiring 100% CPU. On a
PC with 2GB of RAM this could be reliably triggered
by having a fire burn a forest for 20 to 30 minutes.
This patch removes fire node timers completely and
instead extinguishes fire using an ABM.
This patch initializes the random number generator used in mcl_fire with
the current Unix timestamp. It also corrects two biases in fire spread
that were caused by nodes being iterated over in a predictable way.
This patch adds a new test structure to the “/spawnstruct” command which
can be spawned with this command: /spawnstruct test_structure_fireproof
The structure can be used to verify that eternal fire can be spawned by
the structure placement code. It can also be used to debug fire spread,
as according to Minecraft fire spread rules, it should be fireproof.
See <https://minecraft.fandom.com/wiki/Fire#Spread> for those rules.
In Minetest 5.4.1, calling get_player_control() on a mob returned the
empty string. Minetest commit 5eb45e1ea03c6104f007efec6dd9c351f310193d
changed this, so now calling get_player_control() on a mob returns nil.
As mcl_boats defines boats that can have a player or a mob as a driver,
code like the following crashes with a changed get_player_control() API:
local ctrl = driver:get_player_control()
if ctrl.sneak then
detach_object(driver, true)
end
Furthermore, once a world has crashed, joining it near a mob that is the
driver of a boat with such control code immediately crashes again.
When I reported this bug to Minetest, several Minetest core developers
stated that they disliked the old API and proposed other return values
for calling a mob's get_player_control() function – all different from
the empty string. Since I have some doubts that this bug will be fixed
in Minetest 5.5.0, boat code must take into account a nil return value.
Minetest issue: https://github.com/minetest/minetest/issues/11989
Before this patch, wearing a pumpkin would make body armor render as a
corrupted item held in the player's left hand instead of on their body.
Some parts of their armor would also get rendered on the player's feet.
(cherry picked from commit 12192d1a8d)
Before this patch it was possible for any user to to crash Minetest in
creative mode. This was possible because queries in the search field
were interpreted as search patterns for string.find().
A search for a single square bracket would reliably crash the server.
Also, a search for 6000 times the string “a?” would hang the server.
The solution to both bugs is to not interpret the query as a pattern.
Before this patch, growing a gourd (e.g. melon, pumpkin) would always
convert a node west of the node below the stem to dirt if belonged to
the group “dirtifies_below_solid”. This happened because of a loop in
which the variables floorpos and floor were re-used without setting a
new value … therefore, both floorpos and floor were always containing
the last values set in a previous loop instead of the correct values.
This patch fixes the problem by setting both variables in both loops.
The comparison and setting logic in the previous patch that set player
bone positions and properties conditionally incorrectly did not update
some values (like player eye level position) when they changed. This
patch fixes it and adds asserts to ensure the code works as intended.
Before this patch, Mineclonia set (and therefore sent) player bone
positions and player properties in every globalstep. This results in
about 30 TOCLIENT_ACTIVE_OBJECT_MESSAGE per second per player. This
patch adds conditional functions to set bone positions and properties.
The functions set values only when they have changed, reducing traffic.
Commit 5252952555 used string.gsub() to
strip newlines from tools in death messages. The second return value of
string.gsub() (the number of substitutions) was erroneously returned too
by get_tool_name(). This bug caused a crash whenever a skeleton killed a
player using its bow.
Players naming their tools with newlines can mess up chat with death
messages. This commit strips out newlines (\r and \n ) in the tool
name for death messages.
The minetest world is already so small that you can reach world
border from spawn in about 2 hours. I think the regen and fire
resistance are good enough to make them special.
Before this patch, the light level that makes mobs that burn in sunlight
catch fire had been mistakenly specified as minetest.LIGHT_MAX or more.
The correct light level for sunlight is LIGHT_SUN, which is one higher
than minetest.LIGHT_MAX. Since minetest.LIGHT_MAX is the maximum light
value that a node can have and torches emit light at that light level,
mobs that burn in sunlight caught fire inside torch nodes.
• By emerging test areas, the test gets real map data and does not block.
• The test now also ensures that any return values are compared exactly.
• minetest.find_nodes_in_area() is tested with the “grouped” parameter.
For some specific out of bounds values, the volume calculation in
minetest.find_nodes_in_area() is off by about four million nodes.
Unfortunately that behaviour made it trivial to crash Mineclonia,
as Minetest immediately crashes upon encountering large numbers.
This commit introduces a wrapper around minetest.find_nodes_in_area()
which should avoid a crash. Additionally, three self tests are executed
when a server starts; they crash Mineclonia in case the workaround fails.
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.
Though usually one would export directly to "${3}", Inkscape 1.0 had
its command line options changed by people who apparently think that
backwards compatibility is some kind of swear word: Whereas earlier
Inkscape versions would export to a file called foo.png.tmp, newer
behaviour is to ignore the user's wishes & write to foo.png.png –
unless one asks it to write to a filename with a .png extension,
Inkscape 1.0 changes the filename extension to .png each time.
As we do not know the extension of "${3}", we have to use the
extension, then rename the resulting file to the proper name;
only that way the export works with Inkscape 1.0 & earlier …
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.
Mineclonia has inherited mods from MineClone 2 that send a lot of network
packets. This behaviour wastes bandwith and is most likely a major reason
for the unusually high amount of lag that MineClone2 and Mineclonia have.
Many network packets that are sent by Mineclonia are entirely useless.
Analyzing minetest log files to figure out what kind of packets are
sent and how often is a first step in getting rid of useless traffic.
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.
At some point in the past, Minetest had a bug that caused rendering
issues with transparent textures, like those used for banner gradients.
As a workaround, the number of allowed layers was reduced for banners
containing gradients. The engine bug has since been fixed, but the limit
was never removed.
This commit removes the limit.

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.
- the awk script was moved to its own file (deps-to-luacheck.awk) with
minor changes, including added commentary, slightly more rigorous error
checking, and using a different separator model to avoid a second
stage to remove trailing commas
- SED_MODCONF2DEPS was moved to a containing function, and commented
- the awk command itself is now easier on the eyes
tools/make-luacheck-files.sh will generate a .luacheckrc with the
following rules:
- any rules set in the project header (.luacheck.head)
- each mod is allowed to use a single global sharing its mod name
- mod dependency information is parsed, and those mods' globals are
permitted for read access
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.
In mcl_explosions the hitbox used for calculating the damage of an
entity is its collisionbox multiplied by two. This commit removes the
multiplication by two because that makes explosion damage behave weirdly
in some circumstances. It was most likely implemented that way because
of a misinterpretation of the Minecraft wiki.
A bug was introduced in 679e2b1b which caused explosions to not cast
rays for environment destruction in the (+X, +Y, +Z) direction. This
commit fixes that.
