asofold 30902ec352 [BROKEN] Data storage overhaul (basics). (+)
(SAFETY COMMIT)

Largely breaking change.
* Interfaces in front of data types (and 'managers'), some interfaces
removed.
* Data and configuration fetching.
* Check activation checking (config flags, isEnabled, hasBypass).
* CheckType (activation checks, factories removed).
* Lots of collateral signature changes, including IPlayerData.

The (I)WorldDataManager stores per-world data (+ per world per check
type).
* Raw configurations.
* Typical flags: check activation, debug, lag adaption.
* Generic data, such as check configurations or per world check data.

The (I)PlayerDataManager stores per player data.
* Check Data.
* Typical flags: debug
* Exemption
* Check data (and config cache).
* Further mappings and later OfflinePlayerData.
* The registration interface will allow defining, how instances are
handled for registered types (factory, proxy, what on world change, what
on logout, global removal handler, per player removal handler).

(I)PlayerData is intended to be/become the central access point.
* External interface is IPlayerData now.
* Per player debug flags, exemptions.
* Fetching configuration and data: local cache, relaying fetching to
registered factories and proxy-registries/storage (e.g. fetching
configuration from per world storage).

Other fixes/changes:
(+) Extend the debug player command (set true/false, reset to world
default, arbitrary check types).
(+) PlayerData maintains a currentWorldIdentifier (to be used instead of
ChatData in future).
(+) The WorldConfigProvider getAll implementation returns a
LinkedHashSet now, avoiding duplicates.
(+) Move DefaultGenericInstanceRegistry to NCPCore.
(+) Thread-safety considerations for DefaultGenericInstanceRegistry.
(+) Don't log errors on hasBypass checking. TBD: Instead intercept
during listener methods (or even as a feature within the listener node:
e.g. @ThreadContext(primaryThread=true, skipOffContext=true,
cancelOffContext=true).
(+) Add fight.wrongturn permissions to plugin.yml.
(+) Missing GPLv3 headers.

Broken/Missing:
* WorldData inheritance from default: propagate all changes done
directly to the default config to children (all worlds that don't have
an explicit world_config.yml set) - possibly add an OverrideState or
similar, (NONE, FROM_DEFAULT, EXPLICIT) and don't override EXPLICIT if
coming from the default. Calling override on the default WorldData is
not to be confused with calling override for WorldDataManager (override
for all worlds as EXPLICIT).
* Organize overriding for special circumstances (version dependent
activation  and the like). Might want to add registered override
handlers to be called on reload automatically.
* Store generic per check type per world data in the WorldDataManager,
such as configurations and per-world check data. TBD: Factories, cleanup
(!).
* Most efficient referencing (IWorldCheckTypeNode, IHandle<something>?).
* All the registry stuff (see PlayerData).
* Use interfaces for auto registry (and a flag within
RegistrationContext?) - world unload, world change, player join / leave.
* (Data expiration handling including transition to IOfflinePlayerData,
because now data is a little heavier.)
* Further details.

asofold 97d59045ae [BLEEDING][BREAKING][INSTABLE] Swiftly throw in permission caching.
Benefits:
* Improves performance, where permission lookup has major impact, with
timeout based lookup, static permissions (skip permission check
entirely), and world/offline based invalidation. (Once fully
implemented.)
* Hopefully more efficient: use Bukkit Permission for faster defaults.
* (Allows control over how which permission is to be
updated/invalidated, which is useful per se.)

Risks:
* Complex changes yield bugs.
* Other plugins depending on NCP might break.
* Cache incoherence might happen (permissions are changed dynamically +-
unintended malconfiguration, or in case of bugs).
* (Endless loops certainly have all been fixed.)

Breaking:
* Lots of more or less internal API has been changed or removed: Check,
CheckType, CheckUtils, TickTask, ...
* Permission checking behavior has been altered.

Rough points:
* Implement a permission cache within PlayerData.
* Remove the player tasks and permission updates in favour of handling
those within DataManager and PlayerData.
* Adjust everything else to it (partly TBD).
* Updating sets of permissions (e.g. for CHAT) is done more lazily now,
i.e. one per 10 ticks). An actual permission check would still yield an
update next tick (asynchronous).
* Fixed/extended random spots (DualCollection, MiniListener registration
support, StringUtil).

Missing:
* Basic implementation
  * Cleanup after logout (stages: 1. non-essential like permissions,
2. unrecoverable like set-back location, 3. complete data removal).
* Coverage
  * Might have missed spots.
  * NoCheatPlus.nameSetPerms should be replaced by caching + default
config for world-wise updating.
  * Command permissions are always checked. At least for players,
cache based lookup should get implemented.
  * More unit tests.
* Extended configurability: Per-world settings/policies.
* Efficiency
  * Not all parts of the implementation are 100%/optimal yet.

asofold 863b89763d [BREAKING] Move more classes around.
This time the focus is on the utilities package.

Possibly used, but not really official API:
* Move block cache to a 'map' sub-package.
* Move RichBounds/RichEntity/Player-Location and TrigUtil to a location
sub-package.

Not really official API, likely not used:
* Move AttribUtil to compat, since it belongs there.
* Split off direction check methods to collision.CollisionUtil.
* Move static BlockCache methods to map.MapUtil.
* Move food related methods from CheckUtils to InventoryUtil.
* Move vehicle/passenger related methods from CheckUtils to
PassengerUtil.

Not breaking:
* Move IdUtil to commons.

asofold b6088c3e3a [BLEEDING][BREAKING] Registry changes concerning MCAccess.
Main objective is to get rid of too complex setMCAccess methods and to
be able to store handles rather permanently instead.

* Remove MCAccessHolder.
* Add/refine interfaces and implementations.
* Change constructors.

asofold 0868e30994 Allow to detect delegate players for some contexts. Other fix(es).
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

asofold 75aa1b500b Use an interface for trace entries: ITraceEntry
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]

asofold 96d95dff8e [BLEEDING][INSTABLE][BREAKING] Changes (see detailed commit message).
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.

asofold 851203edb9 [BREAKING][BLEEDING] Adjust the API to the upcoming penalty framework.
This is a first step in, which doesn't change the default behavior,
however it might break plugins that rely on certain internals.

PenaltyAction allows to do something with probabilities to consider,
including the possibility to select the first applicable penalty or
applying several penalties. There will be player-specific penalties,
which are applied during ViolationData.executeActions always, and there
will be input-specific penalties, e.g. for applying within the event
listener.

Potentially breaking:
* Return value of executeActions is now void for Action + ViolationData.
* Return value of Check.executeActions is ViolationData now.
* CancelAction is now extending PenaltyAction.
* CancelPenalty may cancel, but might not, due to probability.
* IViolationInfo.hasCancel -> deprecated, now returns willCancel().
* IViolationInfo.willCancel is now used, applicable penalties are
estimated on creation of ViolationData.
* Custom actions can no longer be used to cause cancel. Only penalties
can do so now (due to the return type change). CancelAction is still
there to keep a simple action for canceling.

Not yet:
* InputSpecificPenalty support for fight checks and using them in the
default actions.
* Configuration for penalties (currently only a plugin could override
the action factories, later penalties may have a probability to apply,
reference each other, allow first match, apply several at once).

asofold b2caae38d2 [BREAKING] Group several classes into sub packages for moving. Renames.
* Group selected classes into sub-packages of moving.
* Rename classes.
* Must use LinkedList for velocity entries.
* Prepare SimpleAxisVelocity + entry for use-once accounting.

(Might not be the final naming.)

asofold 04d2896f7e [API CHANGE] Add debug flags to check data [missing: use that one].
For debug output now data.debug is used instead of config.debug, so the
data is initialized with the config.debug value. As an effect of this,
removing the data or reloading will override flags that have been set by
means of API-access only.

Affected:
* Adds getDebug and setDebug to ICheckData.
* Adds appropriate configs to all constructors of check data.
* Some per-check debug flags have been removed.

Extras: 
* spaces
* import cleanup.

asofold ea682417bc [RAW] First version for direction + reach using a moving trace.
This does not change the used methods much, thus it will rather allow
much more cheating, however it allows some basic testing for false
positives. The reach implementation has been slightly optimized to run
faster. The current implementation is not final and only uses trace
elements that were added in the current tick, the latest is always
included.

Next steps will probably be:
* Stricter methods for an individual TraceEntry (demand near-exact hit).
* Don't allow random latency shifting. Maintain a window-thing.
* Probably get rid of the classic method for attacking other entities.

MyPictures add2179dc9 Cleanup "ASCII art" from the sourcecode
Wiped every ASCII related thing that I could find in the NoCheatPlus
source.
2014-02-22 19:26:06 +01:00
asofold 4031cb55e8 [MEANWHILE] Refactor penalty time handling + add one for "item change".
Refactored penalty time handling to use a PenaltyTime object, taking
into account time running backwards, also unify attack (close combat)
penalties to a generic attack penalty. Combined.yawrate still keeps the
timeFreeze penalty, due to also cancelling other actions than melee,
still changed to a PenaltyTime object.

Changing the item in hand now leads to an attack penalty (that also goes 
for not changing the item, but changing the slot).

"Quick" addition, not much testing, except few unit tests.

Note that this could change false detection behavior of other sub-checks
of fight, because the penalty time is checked last. Previously checks
like direction or reach would have cancelled already if the player was 
within their penalty time. Hard to say if this creates new false
positives, but it will be more strict on continuous violations.

asofold ce834675d7 Move most code to NCPCore, removes NCPCompat.
Factories are now on NCPPlugin level, thus all the core stuff can be in
one module, giving better source code browsing.

Updates has been moved into an updates package, because there is to be
expected more content, and to make utilities less fat.

To indicate the direction, the basic infra-structure has been added to
allow adding components to the DefaultComponentFactory. Further
processQueuedSubComponents is now called after each components adding in
order to allow more flexible registry features.
