Confirmed fix for itemframes not showing up. Based on the code in
CraftPainting.
Besids this fix we now pass null itemstacks directly to the
EntityItemFrame to allow the removal of items in ItemFrames.
If the server crashes during chunk generation then the chunk would have never
been added to the executor, this caused a second exception to be thrown when
the server shutdown from the first exception
Adds an check for existing entities before selecting the location allowing
for hanging entities to be spawned in blocks where there already is an
hanging entity at the default rotation.
Fixes the CraftHanging setRotation function to use the new 1.8 logic.
Related to SPIGOT-206.
Currently HangingEntities should be located next to the block they are
hanging on. With the direction set to the opposite of the block they
are hanging from.
This code is modified to find the correct direction.
calling CraftWorld.save() currently does not call WorldSaveEvent, and WorldSaveEvent could fire on worlds that have saving disabled.
New location will always fire during a world save and only during an actual save.

Implementation for the new rotation values. Fixes SPIGOT-93
Up until Minecraft version 1.5 it was not possible to teleport entities
within vehicles. With the 1.5 update came the change in the Minecraft
teleportation logic to dismount before teleporting the entity, if
applicable.
This commit ammends the existing CraftBukkit logic for rejecting
teleportation for entities in vehicles to permit the action. Due to this
change, CraftBukkit is now in-line with Minecraft 1.5 teleportation logic.
When a player dies their inventory is normally scattered over the the area
in which they died. Plugins should be able to modify this behaviour by
defining whether or not the player's inventory will be dropped on the ground or waiting for the player when they eventually respawn.
This commit implements the methods included in the Bukkit half for the new
behaviour by acting upon the boolean flag. The boolean flag is tested
prior to clearing the inventory as well as prior to dropping the items on
the ground. If the flag is true (indicating "keep inventory"), the items
are not removed from the player's inventory and are not dropped on the
ground.
When using a "vanilla" Minecraft server using the "pick block" key on a
command block yields the invoker with a command block within their
inventory while in creative mode. Implications of the invalid items set
containing the command block also include having a "ghost" item that
cannot be placed due to it not actually existing.
This commit resolves the problem and brings Craftbukkit closer to vanilla
behaviour by removing the command block item ID, 137, from the invalid
items set.
Prior to this commit cancelling the PlayerFishEvent would cause various
states of the fishing routine to be incorrectly or wrongly fired. This
incorrect behaviour was due to the miscommunication between the server and
client regarding the fishing state. When the event was cancelled, the
bobber entity was removed and caused the client to incorrectly determine
what the "next state" was to logically be.
This commit resolves the issue by ensuring the client is made aware of the
correct changes at the correct time regarding the bobber entity, therefore
keeping the logical steps of "fishing" proper and in-tact.
Up until this commit the PlayerDropItemEvent, if cancelled, would return
items to the first available slot in the inventory - which is clearly
undesirable as a player and plugin author to deal with.
This commit changes that by ensuring that the item is returned to where
it came from in the player's inventory. This still supports modifying the
drop from the player and will default to "first available slot" if the
item has changed since the event was fired. Other remaining behaviour of
the event is still in tact and has not been modified.
This change improves the quality of life for plugin developers using
iterator iteration with side-effects. In the specified Guava patch, the
internal iterator no longer relies on the AbstractList iterator which
iterates by index, and will instead wrap the provided iterator in a
transformer given the Function.
Many chunk sections contain parts of their data that are the same for
every block they contain. In these cases we can save memory by saving
a single value instead of an array of 4096 copies of that value. Block light
and block data are most likely to be uniform followed closely by sky light
data. Block ids are far less likely to be uniform but give the largest
saving when they are. Because of this we use a compact format for every
part of the chunk. Memory saved from this technique will vary based on the
world but seems to be about 50% on normal Minecraft generated chunks.
This commit centralizes event handling to where damage is actually applied
to the entity to avoid bugs that have resulted from nodamageticks,
modifications to damage after the event has been called, and similar
mishaps. This also implements new API for getting and setting of
modifications made to the damage amount actually applied to the entity.
This is done by storing the change in the damage amount as each modifier
is applied by vanilla code.
The method that actually damages the armor worn by an entity has been
relocated beneath the event called as to not apply durability loss when
the event has been cancelled.
When a chunk is loaded the server tries to ensure it has its initial light
calculations done before sending it to the player. When ticking entities
the server tries to ensure the entity does not walk into an unloaded chunk.
To accomplish these the server checks a one chunk radius around the chunk
to be lit or a two chunk radius around the chunk the entity is in. These
lookups happen every tick even though their result is unlikely to change
that often. To reduce the cost of these checks we replace them with a
system to keep track of what neighbor chunks a chunk has loaded and update
it when chunks load or unload which is a much less frequent action. On a
server with ten players this change removes about 100,000 calls a tick to
LongObjectHashMap's containsKey method.
In commits 71a238ee and c8591397 we added checks while ticking to ensure
we never ticked anything in a chunk meant to be unloaded. We did this to
prevent these chunks being removed from the unload queue and leaked.
However, this causes a ridiculously large number of lookups on the queue
for a somewhat rare occurance. We also now have the chunk GC which will
take care of these leaked chunks when they do happen. With this in mind
we now remove these checks which removes almost all uses of the
LongHashSet backing the unload queue.
After the changes in d611cff2 we started including a mob's equipment when
calling EntityDeathEvent so plugins can access this data. However, the
changes to enable this triggered a bug that makes skeletons and pig zombies
no longer drop equipment because they handle this differently than the rest.
On top of this we don't handle dropping equipment for mobs that cannot
pick up items in vanilla even though vanilla does drop equipment for them
if you summon them with it. We also do not include a horse's inventory
in the event so they drop their saddle, armor, chest, and chest contents
with no way for a plugin to control this.
To solve this issues we revert mob item dropping back to vanilla logic
and instead just capture all their drops in the method they all call to
spawn them into the world. We also move horse inventory dropping so it
happens at a time when we're capturing these drops. With these changes
all items mobs drop on death should now be included in the event and
we have less diff to worry about for future updates.
Waiting to log until after PlayerCommandPreprocessEvent makes the server
not log anything if the event is cancelled. It also makes the server log
what a plugin changed the command to instead of what the player actually
tried to run. As the point of the log is to have a record of every command
a player attempts to run these are both not desirable.
In 7e37cf96 we modified the container logic to handle custom max stack
sizes better and ensure the client stays in sync with this scenario. This
had the effect of sending an extra set slot packet for every inventory
click a player did which was not wanted. These extra packets also cause the
client to recalculate recipes which breaks the result slot for custom
recipes. To avoid the extra packets in general we now only send them if the
max stack is not the one we started with. In the case of a setting a custom
max stack size on a workbench this is still not enough so we also now send
another extra packet to make sure the result slot is always correct.
To handle changes in 1.7.9 we changed skull meta to use GameProfile
instances instead of strings of player names. This reflects what vanilla is
actually storing for skulls now. As skulls still require a name our API was
not changed and we instead look up the rest of the profile information from
the name. The way this was implemented made it so that deserializing a skull
or setting its name potentially involved a network request. As skull meta
itself does not actually require a complete profile we now simply create one
that only contains a name and leave populating it to the server when it is
actually needed.
With the current API it is possible to create an inventory with a specific
type, but it is not possible to give such an inventory a title other than
the default.
The commit changes that by adding a method to optionally supply the title
for the given inventory type and holder, creating the functionality to
display any supported inventory type with a 32 character length String.
If the inventory title supplied is larger than 32 characters then an
IllegalArgumentException is thrown stating so.
In commit 6efeddfe57, TALL_REDWOOD was used instead of the proper TreeType
of MEGA_REDWOOD. Additionally, this fixes an issue in CraftWorld with an
improper boolean flag related to the generation of MEGA_REDWOOD trees.
23 classes have been removed as they are no longer needed using the new
capture logic. This should help quite a bit with future MC updates.
BlockPlaceEvent Refactor
Before calling Item.interactWith, a recording flag is turned on for
setTypeAndData to capture a blockstate for each block that attempts to be set.
When a block place event is cancelled, the recorded blockstate, stack
size, and metadata will revert back to the captured state. If the event is
not cancelled, a notification will be sent to clients and block physics
will be updated.
BlockChangeDelegate Refactor
Now that we have the ability to capture blockstates through world, there
is no need to modify world gen classes with BlockChangeDelegate. Instead
we will simply capture blocks during world generation in order to "replay"
all of the captured blockstates to send back to delegates.
StructureGrowDelegate and BlockSapling.TreeGenerator have also been
removed as part of this change. BlockSapling and BlockMushroom will
capture blockstates the same as block placement and revert back any grow
events if needed.
After the changes in c549609d anvils started incorrectly limiting their
inputs to single item stacks. Vanilla allows for full size stacks here and
this is useful for using materials to repair items so now we do too.
Make sure we check the inventory's max stack size where appropriate and
don't assume the inventory slot is able to take our entire stack just
because it is empty. We also ensure the client is updated with the correct
slot contents and cursor contents in cases where the max stack changes
result in different behavior than the client expected.
The AnvilInventory reports its size as the sum of the ingredient and
result inventories, but when trying to access the slots, only the
ingredient inventory is used, leading to an ArrayIndexOutOfBounds exception.
This change overrides getItem(I) and setItem(I) to use both inventories,
with the slot number adjusted based on their size.
It's currently not possible for a plugin to allow enchanting of an
otherwise un-enchantable item using the enchanting table. This commit
causes EnchantItemEvent to be called with an empty list of enchantments,
allowing a plugin to provide it's own set of enchantments when vanilla
Minecraft would not allow any. It also bypasses the unsafe enchantment check
since a plugin should be permitted to apply any enchantments they like, and
vanilla should not generate unsafe enchantments of its own.
Setting the goal target overrides the entity's will to do something
else. This makes it so entities like wolves with attack another player
with .setTarget(), instead of hanging next to their owner.
Currently, whenever a player places a block in a protected area the
equipped itemstack size on client is never updated properly since the
client thinks the block was placed. The reason this happens is because
ItemStack.matches returns true since the server does not decrement stack
size if a BlockPlaceEvent is cancelled. To correct this on cancel we set
the flag to always update the client regardless of matching.
Currently if a plugin cancels an InventoryOpenEvent for vanilla chests,
the chest animation for clients is stuck in the open state since
IInventory's closeContainer method is never called. To fix the issue,
closeContainer is called before exiting the display GUI method.
If a conversation is abandoned due to a player disconnecting and an
exception is thrown in a ConversationAbandonedListener, the server will
crash. This commit prevents the exception from propagating further up
the stack and instead just logs the error.
Chunk caching in the World class does not know about outdated cache values.
This caused various problems when accessing previously unloaded chunks. The
caching also did not improve the performance so it is removed.
Synchronization is also not necessary, because all accesses to getChunkAt
may only come from the main thread.
Previously, Detector Rails were the only rails that properly called
BlockRedstoneEvent when they changed from powered to unpowered. This commit
adds BlockRedstoneEvent calls for both Powered Rails and Activator Rails.
Currently, plugins can set a player's display name to null, which could
cause issues for other calls to getDisplayName that aren't expecting a null
value. This changes setDisplayName to follow the same logic as
setPlayerListName, which sets the player's name back to their unmodified
"vanilla" name if it receives a null value as a parameter.
Previously, whenever BlockFadeEvent was called for ice melting, it returned
the new BlockState with a type of Material.STATIONARY_WATER. However, in
the Nether, ice melting does not form water, but is simply replaced by air
instead. This changes the event to use the proper BlockState based on
whether the block is located in the Nether or not.
CraftBukkit adds the ability to specify the maxStack size for most
inventories. However, some inventories were not overriding the getMaxStack
method properly, and so the functionality was unavailable. This fixes the
maxStack setting for Anvils, Minecarts, PlayerInventory, and Hoppers.
Previously, the SlotType for the last 4 slots in a player's inventory
returned QUICKBAR when it should have returned SlotType.CONTAINER. This
updates the code for determining slot type to return the proper value.
Previously, the SlotType for the 0 slot in a furnace returned CONTAINER,
when it should have returned SlotType.CRAFTING. This updates the code for
determining slot type to return the proper value.
Previously, when a skeleton was spawned via the spawn(...) function, the
resulting skeleton had no equipped bow and therefore could not properly
attack. This fix gives all skeletons the proper equipment and ensures that
they are able to attack.
Due to changes in how portals were created in Minecraft 1.7, the code that
was previously used to find the blocks involved in the PortalCreateEvent
no longer detected all blocks. Additionally, in the process of updating to
1.7.2, a missed diff resulted in some blocks that were found not being
properly added to the blocklist. This commit corrects that missed diff,
while also adding a check to ensure that the top and bottom of the portal
frame are included in the blocklist.
Adds BUKKIT-5370, BUKKIT-5377, BUKKIT-5378, BUKKIT-5379, BUKKIT-5380,
BUKKIT-5381, BUKKIT-5382. Adds reasons for zombies infecting villagers and
zombie villagers being cured. Readds reason for a skeleton being spawned as
a spider jockey. Adds reason to distinguish ocelot babies from the parent
they spawned with. Adds reasons for chunk generation causing the ender
dragon, villagers, and witches to spawn. And finally, adds a reason for
spawning a chicken mount for a baby zombie.
The old PaintingBreakByEntityEvent was deprecated and replaced by
HangingBreakByEntityEvent. However, in the case of being struck by
lightning, only the deprecated event was being called. This fixes that so
that both the new and old events are called appropriately.
Bans require a name and UUID but our API only allows for a single string
identifier for a ban entry. Until this is sorted out go back to the old
name based setup since we can always get a UUID given a name.
Any new API here needs more thought, skulls require a name but OfflinePlayer
is not guaranteed to have one. There is a Mojang approved way to get a
complete profile from a name but not from a UUID so for now just pretend
this still only uses names.
The getEntries methods on these return player names instead of UUIDs.
As we need the UUIDs for our API we add a getValues method to get at
the data we need. To further ensure we get the most data possible we
also add a way to get at the stored GameProfile to ensure we always
have both the UUID and the name from the list.
In the 1.7.5 update the diff that called book edit events when editing
books was accidentally dropped because of nms changes within the file.
This commit re-adds the craftbukkit call to restore event behavior.
The server's check is for whether or not a player can pass the whitelist
not just if the player is on it. That seems like more useful information
but the API has always just checked if they are on it so this commit
restores that.
When getting an OfflinePlayer by name we lookup their UUID and then
use that to fetch the OfflinePlayer. If the player has not played on
this server before the resulting OfflinePlayer will return null for
getName(). As this is unintuitive we now create the OfflinePlayer directly
using the profile we looked up and make OfflinePlayer prefer that data.
When working with inventories you regularly end up with different
Inventory objects that have the same underlying Minecraft inventory.
Currently, even those these point to the same thing, they are not
considered equal. With this commit comparing any Inventory object that
represents the same inventory will result in equals(Object) returning
true.
The method in EntityLiving to remove a potion effect was remapped during
the 1.7.5 update. The method invocation in CraftLivingEntity was not
updated to invoke the remapped method, which has led to a random method in
LivingEntity being called in its place.
This commit corrects the behavior of removePotionEffect by changing the
method to invoke the remapped method as opposed to EntityLiving#m(float).
Thanks to @gabizou for finding this issue.
Teleporting a player checks to see if the player is disconnected to
try to avoid creating ghost players. The check it uses, however, randomly
fails when the player is in the middle of joining the server. The check
that would work correctly here does not work correctly when the player
actually disconnects. To work around this we add a new flag which is
cleared on the first tick of the new player and assume they are connected
if the flag is set.
When VanillaCommandWrapper dispatches a command containing a
PlayerSelector wtih c>-1 (implicitly true for @a), it loops over the
selected players and exectures the command with each player. However, the
loop index is only incremented if the command fails. As a result, a
successful command is repeated on the same player indefinitely, locking up
the server. This commit fixes the issue by incrementing the loop index
regardless of whether the command succeeds, ensuring the command is only
executed once per player identified by the PlayerSelector.
If a plugin causes an entity to be removed from the world while the
world is ticking entities the ticking loop gets out of sync and fails due
to trying to go beyond the end of the entity array. To ensure this doesn't
happen we store the loop position as a field so we can fix it up in the
entity remove method just like the tick method does when it removes an
entity.
Previously the alias system would pass all arguments from the alias
to its command(s) implicitly. The new system requires arguments to be
explicitly passed so server owners can have more control over where and
how they are passed. To ensure this isn't a breaking change during the
migration from bukkit.yml to commands.yml we now add the $1- argument
to the alias commands to match the previous behavior.
Previously no implementation existed to access various additional
information fields regarding bans. This implementation expands on the
information outlined in the sister Bukkit commit to provide access to
the Minecraft implementation of the ban system.
This implementation of the banning API contains 2 new classes which
provide access to the internal workings of the built-in banning
system within Minecraft.
The CraftBanEntry class simply supports the representation of an internal
Minecraft BanEntry object. The data that may be modified within this new
object must be manually saved to the list contained within the
CraftBanEntry using it's save() method.
The CraftBanList class supports the representation of an internal
Minecraft BanList object through proxy methods. These methods do
validation on the passed objects where needed to ensure safe input to the
backed Minecraft objects.
These changes additionally re-route the existing banning API to the newer,
more detailed, system. Functionality prior to this change still behaves
as documented by the contract defined by the methods changed.
Books can now recieve more than one enchantment. As such, breaking out of
the loop after only 1 enchantment is applied is not the correct behavior.
This commit also reworks some of the logic surrounding the application of
enchantments to the item. By checking if the event doesn't add any
enchantments rather than if the original enchantments list is empty, the
application code is only reached if enchantments are applied, rendering
the "applied" boolean no longer necessary. The ItemStack's Item should only
be set once, so it is now set outside of the loop based upon whether or not
"flag" is true (with "flag" being whether or not the ItemStack's Item is a
book).
Hanging entities are placed into the entity tracker and updates are sent
out to clients for the initial placement. Thereafter data watchers are
configured to monitor the item inside the frame. However, if the
direction the ItemFrame facing changes the entity tracker will not send
out updates.
This commit removes and recreates the ItemFrame entity in the same way
that was already done for Painting entities. This causes clients to
be updated appropriately.
Previously any entities spawned through dispensers (monster eggs) or
by nether portals were given the incorrect SpawnReason of SPAWNER_EGG.
This made it impossible to distinguish what exactly happened in regards
to the creature being spawned.
A method in ItemMonsterEgg has been added to further fine tune reasons
for spawning creatures. This permits the DISPENSE_EGG reason to be used
correctly and accuratly as well as the NETHER_PORTAL reason due to how
BlockPortal spawns the mobs.
The redirected method, a(World, int, double, double, double), is still
called by the ItemMonsterEgg itself and therefore uses the default reason
of SPAWNER_EGG. This does not change previous behaviour.
Prior to this commit, a player disconnected during a respawn event would
remain in memory. This causes a ghosting issue of players in the slot
count and player list, as well as a reference leak.
This commit avoids re-adding the player to the player list (and world) if
they are disconnected. This ensures that the remainder of the respawn
logic is completed as well as ensuring a duplicate player is not left on
the server.
This commit also saves the player's file at the end of the method if they
have been disconnected to ensure that their next login is accurate to the
respawn event's actions. A player that was revived and disconnected will
reconnect as revived.
Currently we use the async chunk loading system only when players trigger
chunk loading. If a chunk is loaded for any other reason it goes through
a separate codepath. This means if a player has trigged a chunk load and
before the chunk loads something else wants the same chunk we will load it
twice and throw away the second result. With this change we instead use
the sync processing feature of the AsynchronousExecutor to load the chunk
which will pull it out of the queue if it was already queued to load. This
means we only ever load a chunk once. Because chunk generation is not
thread safe we still fallback to the vanilla chunk loading system if the
chunk does not currently exist.
Previously we attempted to call interact events in cases that were missing
by modifying the arm swing logic. This, however, was too broad and started
triggering events in cases we already covered leading to duplicates. Since
the only case we can handle cleanly and the primary point of the previous
fix was fluids we now instead simply treat fluids as air for this check.
This also ensures we do not get duplicate events when the player is in a
fluid and hits a normal block, unlike the previous change.
This reverts commit 68b702f7 and replaces it with a better fix.
The block obtained and stored within the block object higher up does not
reflect the block at the location being hit, rather it is the air block
the arrow was previously in. Thusly when the variable is used to check
if the arrow is still in the block, it fails.
Because EntityFireball.setDirection() adds a random offset to passed
parameters, it is not appropriate for use in an API method. As such,
the values need to be directly set to remain accurate.
Previously, trying to launch a ThrownExpBottle or Fish projectile would
result in an IllegalArgumentException. This commit adds support for both
ThrownExpBottle and Fish, which means that all current projectiles are
now properly supported by this method.
Previously, if an error occurred during CraftServer initialization before the
logger was instantiated, it would cause an NPE and the server would never
finish loading properly. By instantiating the logger before attempting to
load anything else in CraftServer, we ensure that a logger will always be
available in the case of any errors.
In 1.7, Minecraft changed Weighted Pressure Plates to allow players and
entities to interact with them, rather than simply changing redstone signal
based on the number of items on the pressure plate. This commit adds calls to
PlayerInteractEvent or EntityInteractEvent for every entity that steps on the
plate.
ItemStacks do not stack if one has null for a tag, while the other has an
empty tag. In CraftItemStack, if you set an item to an empty ItemMeta, it
will create an empty tag for the internal ItemStack.
This changes the setItemMeta function to check for empty meta, and then
use null for the tag instead of an empty NBTTagCompound.
The method being called was renamed during the 1.4.2 update process
but the function call was not replaced accordingly, leading to a
missed diff from 314051580a0a8e4745d3a539f232b552916eb302.
Damage caused by explosions will return null for the event as of
6588d6f72bbca74bf150de65593ac575b846111b. As such, a null check is
now necessary when handling non-living entity damage events.
When falling back to vanilla recipes in the iteration of recipes,
a check is necessary to ensure that vanilla recipes are present.
RecipeIterator has been modified to account for the multi-map setup.
In commit f94b7af8 I delay removing the block until after running the
block's cleanup code to avoid errors. However, this causes problems of
its own due to blocks not being written with this in mind. To avoid blocks
getting recursively removed we now only delay removing containers since
they are the only ones we had problems with to begin with.
When setting a block the server sets the new block ID, calls the cleanup
on the old block, then calls the placement logic for the new block. This
would normally work correctly but we have logic to prevent errors that is
causing one here. When trying to clean up the old block we notice the block
ID has changed and try to fix things, this causes the cleanup logic to
fail. To ensure cleanup happens correctly we now do all the cleanup before
changing the block which avoids triggering the fixup code.
Due to vanilla blanket comparing data values, and the unspecified
order of hashmap iterators, we need to run through custom recipes
first, and therefore separately, to ensure that they are actually
used. By not adding the custom results to the experience table, we do
not override the experience gains from vanilla smelting recipes.
Setting a horse's passenger to a non-living entity will cause a
server crash when the horse ticks, we need to check that it is
a living entity before casting, and skip otherwise.
With the update in 1.7 that improved the server ping, it was made to
include a long version string for CraftBukkit. This value is too long
for proper display so we now send a shortened string consisting of
the server implementation and the minecraft version.
When we first added the reach limiter in CraftBukkit there was no
difference between how far the client could reach in vanilla while in
Survival or Creative. At some point in Minecraft's cycle Creative was
given a block extra to work with and our protection was not updated to
account for this. We need to respect the possibility of different game
modes in Minecraft providing the client with varying reach distances.
Due to an incorrect mapping of this method to a friendly name, we're
unfortunately calling the wrong method within EntityPlayer.reset() to
reset attributes. Instead of what we've mapped as "removeAllEffects", we
should be calling EntityLiving.aP(). This mapping should be corrected in
the next naming version.
In the CraftBlockState implementation, updating the blockstate onto
a block will force the block state data value onto the block.
Unlike vanilla which relied on block data being set when the type
changed, we must instead explicitely set the data in the blockstate.
Minecraft now uses resource packs instead of texture packs, which broke
the setTexturePack method, as the client no longer listens on the MC|TPack
channel.
This commit fixes the issue by adding in a setResourcePack method, and by
deprecating setTexturePack and rewriting it to call the newly added
setResourcePack. In order to simplify the method and prevent this from
happening in the future, setResourcePack calls EntityPlayer.a(String) to use
the same logic as minecraft when sending resource packs.
In Minecraft 1.7, URL processing was removed from the client while the
server gained the ability to designate a URL to be launched in response to
clicking text. However, this functionality is not implemented in the
vanilla server. This commit adds that functionality to messages sent to
the client, processing URLs as clickable.
Additionally, char array iteration is replaced with regex.
When growing trees we use a BlockChangeDelegate which queues up the block
changes so plugins can modify/block/log tree growing. However, we always
check the actual world when checking for existing blocks. This means when
the tree growing code checks to see if putting a leaf in a block is valid
it may incorrectly overwrite a log block that should exist in that
location. To ensure trees grow correctly we now check the delegate itself
for blocks that match the queried location before checking the world.
Commit c576054539790bdeb35285f62863d74b48c0782d removed the chunklist
collection stored in ChunkProviderServer, however it has been partially
restored in some places by 7e1ac0a77129b169704c1e222ff2deb3ab6cd2d2. As
not all references to this were restored, this has caused the chunklist
and chunks collections to become out of sync, resulting in a memory leak.
This commit removes chunklist from ChunkProviderServer again.
When ItemDye is used to place a Cocoa Block, the postPlace() method
should not be called, as data is handled within the ItemDye class.
However, if Cocoa is placed via its block item, postPlace() should
still be called to mirror vanilla behavior.
Due to changes in the generation of trees, the name of the class responsible
for the generation of jungle trees has changed from WorldGenMegaTree to
WorldGenJungleTree. As such, references to WorldGenMegaTree need to be
updated to WorldGenJungleTree to generate the correct type of tree.
Pulled from PR #1277
Several sounds were renamed in Minecraft 1.7, and have been updated
accordingly. Additionally, two sounds, HURT and BREATH, were removed from
Minecraft.
For Cocoa Blocks, Block.getDropType() returns the item form of the Cocoa
block, rather than the Cocoa Bean item. Because of this, Cocoa blocks need
to have explicit handling in order to return the proper drop contents.
Previously, due to the way that death events were called, Blazes only
fired death events when they dropped loot. This change fixes that,
enabling death events for Blazes whenever they die, regardless of loot
drops.
EnderDragons did not call an EntityTargetEvent when they
were targeting random players in the End. This commit
adds that event call into the targeting code.
Explosions directly caused by LivingEntities, such as creepers and tnt lit
by players, have their EntityDamageEvent explicitely handled within
the Explosion class. In order to prevent double events when damage
is handled for other DamageSources, we need return null for explosion
based damage sources.
The EntityLiving dealDamage method will not call an event for the
entity damage caused by an explosion without an associated
entity cause, therefore, the explosion caused by EnderCrystals
needs to be explicitely handled within the EnderDragon class.
Bukkits Visibility API should prevent players from seeing fall particles
of players that they cannot see. This commit alters the handling to
provide an EntityPlayer argument that is later used to determine if they
are visible.
We do ray tracing on arm swings to filter out swings that hit blocks since
punching blocks has its own event handling. However, some blocks cannot
be punched so the air interact type is still valid for them. Luckily
these blocks all have a means to query them so add an additional check
for this and don't fail the check for them.
This changes the logic for furnace smelt event to consider a result of
null (read: air / invalid), which will still consume an item. It also
properly considers item meta in the result, instead of only checking the
item data value.
Log4j takes a long time to load on startup. Before it loads, the server
appears to have frozen as there is no output until after. We now print
a loading message before this happens to let the user know the server
is actually working.
When pistons push/pull blocks they call Entity.move(float, float) to move
entities out of their path. For hanging entities this code path makes them
simply die and drop as an item. We now call an event in this scenario so
plugins can control this behavior.
Some types of damage are handled specially so do not end up returning an
event in handleEntityDamageEvent. To ensure we don't have problems with
these we need to check for them and simply ignore them, as they've been
handled already.
Calling this event allows plugins to react to the situation by simply
handling a normal damage event, possibly using existing code to
handle other entity damage.

A vanilla server does a series of checks for the client black-listing
certain chat types (commands or chat). This change changes a CB
whitelist to the vanilla blacklist behavior.
This implements the detonate method from bukkit by setting the fuse
timer to 0. This makes a firework explode using the normal codepath,
but without waiting for the fuse.
The validation check in CraftMapView.render(CraftPlayer) filters out any
values less than 0. As of Minecraft 1.7, -128 through -113 are valid colors,
so filtering them out prevents some of the new colors from being sent.
This commit fixes the issue by adjusting the validation check to include
any values less than or equal to -113. As the minimum value for a byte is
-128, no invalid colors are included.
WorldGenerator setType and setTypeAndData have their arguments changed to
add in support for CraftBlockChangeDelegate, which changes the method
signature. This change in the method signature breaks any WorldGenerators
that aren't modified to use CraftBlockChangeDelegate.
This commit fixes the issue by readding the old method and maintaining the
CraftBlockChangeDelegate method. This makes it so that there is a
compatible method for both CraftBlockChangeDelegate WorldGenerators and
unmodified WorldGenerators.
Additionally, this commit reduces and corrects the diffs in
WorldGenerator, moving the fix for layering violations to
CraftBlockChangeDelegate.
A Block object is now passed in place of the previous id value, so the
obfuscated name for all subsequent arguments was shifted. As such,
BlockCanBuildEvent was using the incorrect values for both the material
and the location of the event.
This is corrected by swapping the values into the correct order and
providing an id based upon the Block passed into the method.
CraftBukkit modifies the IRecipe interface, adding new methods, so all
classes that implement IRecipe need to be imported and modified to add the
new methods.
Extending ShapelessRecipes implements the added methods and allows
RecipeBookClone to work with the Recipes API in a way that is consistent
with similar recipes, even if the recipe information present in the API
isn't technically correct.
Adding or removing operators was mistakenly using a loose player lookup
method, which would cause a permission refreshes on an online player whos
name starts with the name of the (offline) opped player.
Add/Remove op operations are exact name match only and the permission
refresh will behave the same way.
Both log4j and our own jline/jansi initialization attempt to catch
errors caused by jansi's use of native libraries. However both of them use
the Exception type which does not catch all errors. On Windows Server 2008
R2 Enterprise without installing extra software the required C++ libraries
are not available which causes an error that does not extend Exception. To
ensure we catch all errors I've changed both of these to catch Throwable
instead which gets us a working console minus jansi functionality.
l previously was the block id, however Minecraft's refactoring means that
the method is now passed a Block reference rather than the id. l is now
the data value of the block, so the block retrieved with that value is not
the correct block to be testing.
Something the log4j ConsoleAppender does makes the console work correctly
on Windows. After trying to pull pieces of it out and run them manually
I decided to just put the appender back. We now once again start with the
ConsoleAppender then remove it immediately after starting.
WorldMapCollection stores scoreboard, map (item), structure, and
village information. Scoreboards are explicitly handled globally,
while villages and structures are erroneously shared.
This commit separates the WorldMapCollections to not be shared among
custom worlds. Maps are special-cased to maintain the previous shared
behavior.
This change will print a warning when a plugin induces a forced save. A
player or console forcing a save (via a command) is ignored for purposes
of printing a warning.
When Minecraft first introduced an auto-save feature, we
were taken by surprise by how much of an impact it actually had on the performance
of the server. After investigating the potential causes of the significant
slow-downs we saw at the time, we came to the conclusion that it was a
combination of the auto-save interval being incredibly frequent and
servers already having an auto-save solution that was conflicting with the
newly added built-in one.
Since we noticed that most servers already had their own auto-save
solution, we decided to completely disable the built in auto-save by
default. In hindsight, however, we were so happy that we discovered and
squashed the cause of the performance issues that we forgot to consider
the future and, as a result, some servers have unfortunately been caught
by surprise when they ran their servers without any auto-save plugins.
Without the auto-save plugin conflict, however, Minecraft's default save
interval of 45 seconds is not suitable for the types of servers that run
Bukkit, to the point where it was negatively impacting performance. As
such, we've decided to re-enable the built in auto-save at an interval of
5 minutes for newly created servers.
The WorldMapCollection object for SecondaryWorldServers(Nether, End) is
shared with the main world, so saving it again for each SecondaryWorldServer
is redundant.
This commit removes the redundant call by checking if the WorldServer is an
instanceof SecondaryWorldServer before invoking worldMaps.a().
The recent Minecraft update rendered the
e20e50f85083dc53cb5456254bcf5781ef750daa fix incorrect by adding a
compound name to the base tag in some code. This fix changes all uses
of tag changes to explicitly use a name.
When a "uid.dat" file is corrupt (empty or <16 bytes), WorldNBTStorage
will silently fail to read and return null. Non-null behavior is
expected everywhere that this value is used.
This change will force a random UUID when the previous UUID cannot be
read, and getUUID to no longer silently ignore read/write exceptions.
This change adds the location and a more specific message to the
IllegalArgumentException that gets thrown when a hanging entity is being
spawned in a location that it cannot survive.
Opening a hopper inventory created by Server.createInventory will
currently have no effect as proper handling code is missing in
CraftEntityHuman for hopper inventories that aren't associated with a tile
entity or minecart. Initialization logic for hoppers is also missing from
CraftContainer, which is necessary for the opening of custom hopper
inventories.
This commit fixes the two aforementioned by adding proper handling to
CraftHumanEntity for opening inventories not associated with a tile
entity, and by adding initialization logic for hoppers to CraftContainer.
Previously fires spawned by lightning strikes were in the wrong locations.
This introduced the possibility of having blocks replaced when they should
not be.
EntityLightning now uses the correct locations as defined to spawn the
fires when needed.
When an entity is being moved as the passenger of an entity from one
entity to another, a VehicleExitEvent is fired, but it is assumed that the
current entity is a Vehicle. However, entities can be passengers of more than
just Vehicles, which causes a ClassCastException to be thrown.
This commit fixes the issue by checking that the current entity's vehicle's
bukkitEntity is an instance of Vehicle before casting it to Vehicle.
Prior to this change when a plugin called Player.hasLineOfSite() the
method would always return false because EntityHuman does not extend
EntityInsentient. This commit changes that by explicitly checking for
line of sight between two entities and returning that value.
Maven paths that include spaces (and possible other characters) get
improperly translated when using a file handle from a URL. This changes
the unit test to open a stream directly from the URL, providing proper
file resolution on multiple platforms.
This commit removes chat wrapping. It is no longer needed, as clients
properly render lines with line breaks.
This commit also changes an outgoing chat message to use the vanilla
behavior for indicating a client cannot chat with commands-only setting.
If a plugin generates an exception when returning a world generator, the
server will crash. This change adds a try-catch block to keep the server
from crashing on plugin defined world generators.
Custom inventories currently do not validate the titles provided. Null values
cause NPEs when writing packets. Values longer than 32 characters
disconnect clients.
This change throws and IllegalArgumentException for null titles or titles
longer than 32 characters.
The unleash event is only called for animals that are sitting - ones that
receive no movement vector. This adds the missing event call for
non-sitting animals.
When only considering trackers from player perspective, attach entity
packet could be sent before a packet for a respective vehicle is in view
and will, in turn, be ignored.
This adds another notification when the vehicle comes into view to cover
all cases.
