### Features
* Fully abstracts serialization by using compile-time attributes.
* Supports serializing the following:
- Primitives (integers, strings, etc)
- IP Addresses
- BigDecimal
- DateTime, Delta DateTimes
- TimeSpan
- Server.Race
- Server.Map
- Point2D, Point3D, Rect2D, Rect3D
- Existing/New `ISerializable` references
- Lists/Sets of serializable types
- Type with a `Serialize` method and constructor that takes an `IGenericReader`
* Supports forward-only migration
* Supports existing RunUO deserialization for older versions by changing to the following signature:
- `public void OldDeserialize(IGenericReader reader, int version)`
- Must remove deserializing the version since this is already done
* Supports serializing from private fields or custom made properties.
* Types do not require inheriting Item/Mobile. Code gen will fully create `ISerializable` information.
- This is not recommended yet, since it requires wiring to `Persistence` which will cause lots of unresolved symbol errors until code gen is built.
### Example
```cs
using System.Collections.Generic;
namespace Server.Items
{
[Serializable(1)]
public partial class TestItem1 : Item
{
[SerializableField(1)]
[SerializableFieldAttr("[CommandProperty(AccessLevel.Administrator)]")]
private List<Item> _someProperty;
private void Deserialize(IGenericReader reader, int version)
{
}
}
}
```
Generates this:
```cs
namespace Server.Items
{
public partial class TestItem1
{
#pragma warning disable 0414
private const int _version = 1;
#pragma warning restore 0414
[CommandProperty(AccessLevel.Administrator)]
public System.Collections.Generic.List<Server.Item> SomeProperty
{
get => _someProperty;
set
{
if (value != _someProperty)
{
((ISerializable)this).MarkDirty();
_someProperty = value;
}
}
}
public TestItem1(Serial serial) : base(serial)
{
}
public override void Serialize(IGenericWriter writer)
{
var savePosition = ((Server.ISerializable)this).SavePosition;
if (savePosition > -1)
{
writer.Seek(savePosition, System.IO.SeekOrigin.Begin);
return;
}
writer.WriteEncodedInt(_version);
writer.Write(_someProperty);
}
public override void Deserialize(IGenericReader reader)
{
var version = reader.ReadEncodedInt();
if (version < 1)
{
OldDeserialize(reader, version);
((Server.ISerializable)this).MarkDirty();
return;
}
SomeProperty = reader.ReadEntityList<Server.Item>();
}
}
}
```
And this:
```json
{
"version": 1,
"type": "TestItem1",
"properties": [
{
"name": "SomeProperty",
"type": "System.Collections.Generic.List\u003CServer.Item\u003E",
"rule": "ListMigrationRule",
"ruleArguments": [
"Server.Item",
"SerializableInterfaceMigrationRule"
]
}
]
}
```
- [X] Adds a property to `CommandProperty` to allow modifying `PropertyObject` where there is no property setter that is accessible.
- [X] Updates AosAttributes and friends
Example of how to make this work:
```cs
[CommandProperty(AccessLevel.GameMaster, canModify: true)]
public AosWeaponAttributes WeaponAttributes { get; private set; }
```
This fix is necessary because in release mode the optimizer will sometimes _entirely remove the setter_ because it knows it can do something that is more efficient _when the property setter is private_. RunUO got around this by declaring a public setter explicitly that _was empty_.

- [X] Caches DateTime.NowUtc on the game loop (not other threads)
- [X] Replaces all locations where it makes sense
- [X] Adds Min/Max for `IComparable` (TimeSpan, DateTimes, etc)
Closes#261
- [X] Adds `Respawn` command
- [X] Adds `EditSpawner` command
- Usage: `[global editspawner <type> <arguments> set <properties>`
- This command replaces the arguments (optional) and properties of the affected spawners for that type
- [X] Adds `SpawnProps` command
- Usage: `[area spawnprops`
- This command brings up a gump to modify targeted spawners based on the targeted entity.
- To do this, the props/values are copied and then used to construct a properties list for the spawner entry.
Closes#531
- [X] Fixes map issues at New Haven by turning off static diffs
- [X] Some code cleanup and reformatting of tile matrix, tile matrix patch, and tile data
- [X] Adds NetState.Flush for generating spawners so it doesn't feel like the server is frozen
- [X] Reverts NativeReader changes from a while back.
- [X] Adds more string reading for BufferReader.
Notes:
BufferReader is still `little endian` compared to `SpanReader` which is `big endian` (for packets). To that end, the RunUO deserialization `ReadString()` was made obsolete since it is ambiguous, and contains extra fields other than simply reading a string. Furthermore, we shouldn't be using UTF8 (for now) since it is slow.
- [X] Removes network pause/resume
- [X] Adds back packet profiler
- [X] Adds state machine to keep track and trace netstates
- [X] Changes NetState.Running back to using an interlock exchange
- [X] Adds preliminary packet throttling support
### Packet Throttling
- `[GetThrottle <packetId>` to get the delay in milliseconds for that packet
- `[SetThrottle <packetId> <delay>` to set the delay in milliseconds for that packet
The settings are saved to `Configuration/throttles.json`
- [X] Fixes some issues with the type caching
- [X] Changes type check default to ignore case
- [X] Splits out type caching of insensitive and sensitive lists. This means less stuff to iterate through when checking a type against the string.
- [X] Adds an ArrayEnumerator, mostly for reference purposes (copy/paste as needed)
- [X] Removes some uses of linq
- [X] Creates struct based enumerator for Skills
- [X] Creates a struct based enumerator for TypeCache
- [X] Changes HarvestDefinition to an init array instead of List
- [X] Changes HeritageTokenGump Response from List to Array
- [X] Adds a stop music packet
- [X] Converts chat packets
- [X] Breaks out chat code a little bit more
- [X] Converts character statue animation packet
- [X] Renames some folders to have spaces
- [X] Organizes and consolidates incoming/outgoing packets for other content
- [X] Fixes virtual checks
- [X] Removes 6017 handler since it is only used in one place
- [X] Exposes a ref int to modify the packet length. This is acceptable since we technically have access to the entire reader/buffer.
- [X] Fixes a bug with RunUO where direction is set multiple times and the run flag is not set properly.
TODO: Fix other direction/movement issues and duplicate packets.
Bumps release version
- [X] Adds support for `SkipLocalsInitAttribute`. SkipLocalsInitAttribute skips initializing stack variables including `stackalloc`. I don't think it is wired/working yet but should be implemented soon.
- [X] Optimizes broadcasted packets by checking if the first byte (packet ID) is non-zero. If it is already set, it reuses the buffer.
- [X] Removes unnecessary refs to Spans. I don't think the Span struct itself is mutable, so a ref is not helpful.
- [X] Fixes an issue where a buffer smaller than 8 bytes would not double with enough space in some cases.
- [X] Fixes an issue with dupe copying the savebuffer reference (ugh).
- [X] Streamlines the IGenericWriter API to use better generics.
- [X] Streamlines the IGenericReader API to use better generics.
- [X] Forces `tidying` of a List/HashSet to be done externally since Writers/Readers should not have side effects.
- [X] Fixes an issue where Tidying a list didn't TrimExcess, causing memory leaks.
- [X] Reverted the meaning of `World.Running` to specifically refer to any world state post world loading.
- NOTE: Do not use this if you want to block on world saves. Instead use checks against `WorldState.Saving` states.
- [X] Fixes an issue with serializing negative DateTime deltas.
- [X] Fixes a potential issue with serializing non-UTC DateTime.
Bumps release version
- [X] Removes some string allocations (e.g. split)
- [X] Optimizes some collections
- [X] Converts insensitive to extension methods of built-ins.
- [X] Adds ordinal (case sensitive) string helpers
- [X] Fixes conditionals for in-game commands so they use Ordinal comparisons.
- [X] Replaces ToLower.Contains with InsensitiveContains
- [X] Adds ValueStringBuilder
- [X] Implements ValueStringBuilder in a few places where it makes sense
- [X] Removes the redundant Wrap function and replaces it with an optimized version
- [X] Fixes list conversions in Utility
Closes#351
Bumps release version
- [X] Fixes an edge case where the cycle index goes negative and crashes
- [X] Fixes average CPS calculation
- [X] Fixes issue with logout delay
- [X] Bumps release version
