GOALS

Architecture

• Upgrade Server/Scripts compiler to use Roslyn/C# 7
• Upgrade the code to use C# 7 standards

Administration

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

Serialization & World Saves

• Remove Serialization/Deserialization entirely
• 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
• Asynchronously offload the transaction to another service for permanent serialization
  • Support basic KVP databases such as MongoDB, RocksDB, and Redis
• 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
• Improve asynchronous socket handling

Code Architecture Fixes

• Create a LayeredItem child and move related code to that class. All layered items should inherit that.
  • Items that are placed on the paperdoll will need to inherit this.
• Create a StackedItem child and move related code to that class.
  • Items that have an amount will need to inherit this.

Bugs & Misc

• Naked corpses (container display issue)
• Rounding errors with new bank system
• Replace double with int for skills to fix rounding errors and optimize code
• 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
• Consuming items are deleted directly in several places instead of using Item.Consume()
• Content displaying for newer clients is not working properly in several situations
• Stack/Hold checks are broken in certain situations
