- Logging System is asyncronous to improve performance.
- Each msg and Logger has a Log Type and Log Level assigned. Each msg is assigned the Logger of same Log Type or "root" Logger is selected if there is no Logger configured for the given Log Type
- Loggers have a list of Appenders to send the msg to. The Msg in the Logger is not sent to Appenders if the msg LogLevel is lower than Logger LogLevel.
- There are three (at the moment) types of Appenders: Console, File or DB (this is WIP, not working ATM). Msg is not written to the resource if msg LogLevel is lower than Appender LogLevel.
- Appender and Console Log levels can be changed while server is active with command '.set loglevel (a/l) name level'
Explanation of use with Sample config:
Appender.Console.Type=1 (1 = Console)
Appender.Console.Level=2 (2 = Debug)
Appender.Server.Type=2 (2 = File)
Appender.Server.Level=3 (3 = Info)
Appender.Server.File=Server.log
Appender.SQL.Type=2 (2 = File)
Appender.SQL.Level=1 (1 = Trace)
Appender.SQL.File=sql.log
Appenders=Console Server (NOTE: SQL has not been included here... that will make core ignore the config for "SQL" as it's not in this list)
Logger.root.Type=0 (0 = Default - if it's not created by config, server will create it with LogLevel = DISABLED)
Logger.root.Level=5 (5 = Error)
Logger.root.Appenders=Console
Logger.SQL.Type=26 (26 = SQL)
Logger.SQL.Level=3 (2 = Debug)
Logger.SQL.Appenders=Console Server SQL
Logger.SomeRandomName.Type=24 (24 = Guild)
Logger.SomeRandomName.Level=5 (5 = Error)
Loggers=root SQL SomeRandomName
* At loading Appender SQL will be ignored, as it's not present on "Appenders"
* sLog->outDebug(LOG_FILTER_GUILD, "Some log msg related to Guilds")
- Msg is sent to Logger of Type LOG_FILTER_GUILD (24). Logger with name SomeRandomName is found but it's LogLevel = 5 and Msg LogLevel=2... Msg is not logged
* sLog->outError(LOG_FILTER_GUILD, "Some error log msg related to Guilds")
- Msg is sent to Logger of Type LOG_FILTER_GUILD (24). Logger with name SomeRandomeName is found with proper LogLevel but Logger does not have any Appenders assigned to that logger... Msg is not logged
* sLog->outDebug(LOG_FILTER_SQL, "Some msg related to SQLs")
- Msg is sent to Logger SQL (matches type), as it matches LogLevel the msg is sent to Appenders Console, Server and SQL
- Appender Console has lower Log Level: Msg is logged to Console
- Appender Server has higher Log Level: Msg is not logged to file
- Appender SQL has lower Log Level: Msg is logged to file sql.log
* sLog->outDebug(LOG_FILTER_BATTLEGROUND, "Some msg related to Battelgrounds")
- Msg is sent to Logger root (Type 0) as no Logger was found with Type LOG_FILTER_BATTLEGROUND (13). As Logger has higher LogLevel msg is not sent to any appender
* sLog->outError(LOG_FILTER_BATTLEGROUND, "Some error msg related to Battelgrounds")
- Msg is sent to Logger root (Type 0) as no Logger was found with Type LOG_FILTER_BATTLEGROUND (13). Msg has lower LogLevel and is sent to Appender Console
- Appender Console has lower LogLevel: Msg is logged to Console
- Implement UNIT_FIELD_HOVERHEIGHT (requires DB data). This field, sent in update object packet, will determine the height at which a creature hovers if it has movementflag_hover applied. Note that hovering will now update the server-sided z-coordinate by the value of this field, and that all subsequent positional updates to the client will need to send z coordinate MINUS the hover height offset, or the hoverheight will be visually doubled client side.
- Correct our usage of movementflag_flying, movementflag_can_fly, movementflag_hover and movementflag_disable_gravity (previously levitate), and how they relate to InhabitType in the database. This fixes "flying creatures on steroids" bug (wings flapping too fast), and potentially a lot of visual issues in AI scripts. Note that a lot of scripts still set wrong movementflags, these need to be fixed on a case by case basis.
- Send correct packets for SPELL_AURA_FEATHER_FALL, SPELL_AURA_WATER_WALK and SPELL_AURA_HOVER apply/unapply.
- Send correct packet contents for movement update in Unit::SetSpeed.
- Misc. cleanup in affected scripts.
Spline movement controls movements of server-side controlled units (monster movement, taxi movement, etc).
Proper implementation of effects such as charge, jump, cyclic movement will rely on it.
However, need improve our states system before.
Technical changes:
* Added linear, catmullrom and bezier3 splines which based on client's algorthims. They can be reused for proper transport position interpolation.
* Precission increased. There are no more position desync issues since client's position calculation formulas used.
* Now possible to move by paths with multiple points, send whole path to client.

Original port for Trinity (ref #4629) Chaplain and Venugh
With the following incremental fixes during my review:
- Restore flightmaster end grid pre-loading
- Fix uninitialized Creature::m_path_id
- Add missing trinity_string entries for .movegens command
- Fix a bug in WaypointMovementGenerator that would trigger unexpected pausing at waypoints for various amounts of time
Known issues:
- Errors like WaypointMovementGenerator::LoadPath creature XXX (Entry: YYYYY GUID: ZZZZZZ) doesn't have waypoint path id: 0.
This is caused by bad DB data. This commit didn't "break" it.
Do not forget to re-run CMake before compiling.
