* Add a way to stay updated about the latest registration state for a
class.
* Add a class for the registry.
* Let the registry log all registrations.
* Make super interfaces for LogManager (simple logging of
String/Throwable).
Missing:
* More streams (REGISTRY, PLAYER/CHECK_STATUS/EVENTS or just CHECKS at
least). Make status rather the plugin status. Registry could have an
extra file.
* More efficient IGenericInstanceHandle use (wrap + reference counting).
Attempt to treat fake players less Concept is subject to change, might
want fall-back methods or skipping native access in general where it's
not needed (thus not need to check for native entities).
Other
* Don't insert dataMan into disableListeners twice.
This is neither complete nor final. Intentions are to group interfaces
better, rather organizing packages in a flat way.
At some point there will be other major move-arounds, but that'll
hopefully be a point where we have a better idea of where to put what
(...). For now the approach is to move interfaces/things rather where
it's not interfering with profane exemption API use, preferably neither
taking down the top level API layer
(NoCheatPlusAPI).
Added deprecated interfaces to prevent cncp to break too quickly.
Outlook:
* Classes that are rather only expected to be used internally for setup
will likely get moved around freely.
* Classes that have been added since last release might also get moved
around freely.
In order to simplify the pom.xml files, we now work with a ncp_base
(formerly 'minimal')
profile for the minimal configuration and demand this to be activated in
addition to other profiles. This means the build parameter 'ncp_base'
can/should be used as well. See the README.md for a table of build
profiles).
Perhaps later there will be extra settings and an extra log file for
registry/setup related output, while real errors would still be logged
to file/console.
Configurable. Falling blocks, piston, end portal, roughly. Destructive:
the entity is removed.
(In addition some of the feature tags are added regardless activation
flags, because 'ncp reload' could change things anyway.)
Feel free to suggest alternatives/variations...
* Make RayTracing and PassableRayTracing implement interfaces. (rough,
not used in tests yet etc.).
* Optimize ray tracing use in BlockProperties.
* Add an axis-wise implementation (buggy, hardly tested, thus not used
yet).
MCAccess will be split into smaller providers with time, so do expect
more breaking changes of this type. If this is an issue, please contact
us, so we can see how to smoothen things. E.g. we could still make
MCAccess an aggregate, that just delegates to the more fine grained
providers, or we could provide other
(default) aggregates.
This also adds a Bukkit-based provider for future updates.
Since merging by distance only creates false positives (one would have
to increase the bounding box for an entry, but the angles would never be
100% right), we never merge, instead we don't add a new entry if the
position is the same, the time value is not updated in this case. For
validity of an entry you always have to consider the time span until the
previous (younger) entry or until now for the latest entry.
Rough changes:
* Use an interface for accessing trace entries.
* Use a linked structure for the actual trace.
* Use maximum age and size to limit the number of stored entries.
* Use a pool to somewhat limit object creation (size may need
configuration or scaling with number of players).
* Since the trace starts empty, have the field be final.
* Keep trace elements if settings are changed, cut size if necessary.
* Remove obsolete tests.
Potentially missing:
* Usage of LocationTrace has not been checked if we need to account for
the time of the latest entry not necessarily being updated (!).
* New tests, e.g. accounting for the expiration of entries.
Follow ups:
* (Extend fight/loop checks to a latency window mechanism.)
Upcoming changes will roughly be:
* Change implementation to a double linked structure.
* Implement/use something like ListIterator.
* Never merge entries, instead use some pool and time/extre-n as limits.
* A basic latency window implementation just for the LocationTrace for
preliminary experiments. [Track hit/miss all time + recent so and so
seconds, some extra cancelling/invalidation mechanics, allow to test
complement 0->window start and possibly window-end-> max latency for
some cases, cancelling mechanics may contain a buffer or a mixture of a
buffer relating to average miss rate]
Prepare using VehicleUpdate and PlayerMove instead of VehicleMove for
vehicle moving. This change isn't intended to change
anything/much on the surface.
* Implement native IEntityAccessPositionAndLook for 1.9_R1 and 1.9_R2.
* Alter method visibility and parameters.
* Common pre-conditions.
* Route contents of both VehicleUpdateEvent and PlayerMoveEvent through
a common related method (also named onVehicleUpdate).
* Remove RichLivingEntityLocation, to be able to simplify more.
* Refine interfaces for locations (IGet... ISet... vs, I... for both).
* Implement location related interfaces in some places, related changes.
* Override hashCode for some of the location related classes. Use that
for storing location hashes instead of Location.hashCode. Auxiliary
methods for hashCode in LocUtil.
* Add onIce to LocationData.
* Renaming player vs. vehicles (likely incomplete).
* Possibly other related/random changes.
Line count is high for this change, despite not so complex. Next step is
to change VehicleChecks to use past move tracking to estimate from where
a vehicle is moving (left not compiling). Due to the lack of teleport
events, and due to entity last location being mostly useless, we have no
choice but to hard-set-back on anything that looks strange.
Directly following:
* Boat fly check based on VehicleUpdateEvent and fetching last pos.
* Implement a native access based provider for
EntityAccessLastPositionAndLook, after testing the reflection based one.
Likely following:
* Implement the same fly checks based on PlayerMoveEvent for horses and
pigs too, for the case server-side fly checking is disabled.
* Configurability for individual types of enbtities, at least a flag for
activation.
* Not sure if a fall-back to VehicleMoveEvent should be kept, setup
shouldn't be all too complicated.
Major: Sketch vehicle envelope check.
* Renaming fields, methods, packages. Moving classes to other packages.
* Additions and refactoring for set-back handling and location tracking.
* Increase amount of debug logging.
* Adjustments to current vehicle set back handling.
* AuxMoving: call clear() on setMCAccess.
Minor: Adjust block change tracking implementation.
* Use a class instead of an id, in order to keep track of used entries.
* Allow reuse of an id, if the block still is intersecting.
* Improves situation for simple setup, issues remaining:
* Random UNKNOWN teleport by server potentially interfering.
* Distances > 1.0, possibly resulting from split move handling.
* On-ground estimation and passable.
* Blocks with gravity are worse (likely on-ground).
* More in-depth checking of constraints of implementation.
* Note that the block change tracker currently is disabled by default.
Naming:
* Possibly not final.
* survivalfly: Does not fit at all.
* Separate official checks + sections for speed and fly: nope.
* runfly: not running.
* speedfly: mix up with too fast flying.
* moving: too much redundancy with moving.vehicle.moving
* envelope: so and so, possibly better with tags to be set.
Content:
* Prepare a vehicle moving envelope check (just basic pre-coding
bookkeeping and refactoring).
* Split vehicle checks to another class. Needs refactoring.
* Add ability for simple generic instance registration by an interface.
* Add new sub check type MOVING_VEHICLE, with configuration section,
move existing stuff there (moving.vehicles.., morepacketsvehicle).
* Breaks at least the use of check type MOVING_MOREPACKETSVEHICLE.
FunFact:
* Try CheckType setup with MOVING_MOREPACKETS_VEHICLE(MOVING, ...) to
see why there is a test for this kind of thing.
Bugs:
* Old configuration paths don't seem to get removed with @Moved.
Missing:
* More refined vehicle checks.
Issues on quick testing:
* End portal seems bugged, resulting in desync, entering in creative
mode. Switching to survival via console allows end portal travel after
kick+relog. Can't tell if this is a 1.9 bug or due to building NCP vs.
an older version of ProtocolLib.
This won't cover all effects of internal changes, some blocks might be
interpreted wrongly still, some shapes may have changed in an
incompatible way (e.g. skulls).
