GOALS

Architecture

  • Upgrade Server/Scripts to target .NET Core 3
  • Upgrade the code to use C# 8 standards
  • Remove compilation of scripts at startup in favor of loading DLLs.
  • Support configuration via a modernuo.json file

Networking

  • Replace Packet classes with functions
  • Improve asynchronous socket handling using Pipes
  • Improve socket handling (2-5x) and event loop using libuv

Administration

  • Move IP logging and account data to SQL
  • Move account management to web

Serialization & World Saves

  • Create a flag to indicate when objects will be serialized.
    • Players, all items held by players, houses, etc.
  • Create transactions which handle changes to objects including:
    • Transitioning from not serialized to serialized (created)
    • Transitioning from serialized to not serialized (deleted)
    • Property value changes
  • Create asynchronous request from cold storage
    • External system must provide objects and their nested objects (e.g. containers)

Optimizations for large shards

  • Eject inactive players and their items after they are serialized to cold storage
  • Create hydration techniques for non-persisted systems (e.g. spawners, decorations, static, champions, etc)
  • Simplify certain items by eliminating all of their individual types and using an enum to reference their individual type
    • Items subject to change: reagents, logs, ore, ingots, potions, and containers
    • Syntax change: new MandrakeRoot() -> new Reagent(ReagentType.MandrakeRoot)
  • Create object pools for high availability items such as gold and reagents
    • For example, new MandrakeRoot() -> ObjectPool.Get<Reagent>(ReagentType.MandrakeRoot).
    • Pools should be elastic and adjust according to nominal usage. For example, if thousands of gold objects are created and destroyed in a small period of time, the pool should be expanded and replenished properly so it is never empty, or full.
  • Replace timer system with a wheel implementation
  • Create DefaultName for mobiles

Plugins (Separate Repos & Optional)

  • RunUO 2.0 Migration Utility
    • Template code for updating serializations
    • Convert World file and dump to new serialization technique if there is one
  • Login/Auth Gateway (Like OSI!)
    • Use central AuthID via redis or similar
    • Support 2FA Auths via at login gump
  • 2FA Auth at Login to prevent password theft
    • Support Authy via universal interface
    • Support external app/device, magic number email, SMS, and FCM
    • Support user identity via web browser to curb flooding
  • Serialization via Database (no world saves)
    • Asynchronously offload the transaction to another service for permanent serialization
    • Support basic KVP databases such as MongoDB, RocksDB, and Redis, etc.

Bugs & Misc

  • Rounding errors with new bank system
  • Replace specific checks for Item/Mobile by extended IEntity and mainstreaming the NEWPARENT code
  • TryDropItem dropping items until it fails when it should be all-or-nothing
  • Consumable items are deleted directly in several places instead of using Item.Consume()
  • Stack/Hold checks are broken in certain situations
