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 6dbb7d4299 [BREAKING ] Lazy permission updating.
* Each asynchronous permission check yields an update request anyway,
thus frequent bulk update requests have been removed.
* With join and world change, lazy permission updating is requested.

Breaking:
* Remove CheckConfig.getCachePermissions().

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 c7d72101c2 Make cancelling flying/waiting packets configurable. 2017-04-29 10:12:18 +02:00
asofold fc24fe529c [BLEEDING] Overall packet spam check for pre-1.9.
Not sure if this really pays, if most people use protocol-support
plugins that limit packets anyway. There could be some future use, e.g.
generic rate limiting with configurable implementation.

Other:
* New methods for RawConfigFile+ConfigManager to check for
AlmostBooleanS.
* Add all net check permissions to plugin.yml.
