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.
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.
A method has been added to Player which allows the server to send a sound string to the client. Assuming the client has the specified sound, it will be played. This is needed by the implementation of the /playsound command.
Items that cause entities to change state, including tags, chest, and
leashes, do not update the client properly following the firing of
PlayerInteractEntityEvent. This change makes the item checks occur
before the event fires, to concur with the client's assumptions.
