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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
