- 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
* Call spell effect handlers in 4 modes:
- SPELL_EFFECT_HANDLE_LAUNCH - called when spell is launched (cast just finished)
- SPELL_EFFECT_HANDLE_LAUNCH_TARGET - called when spell is launched for each target in spell target map
- SPELL_EFFECT_HANDLE_HIT - called when spell hits its destination
- SPELL_EFFECT_HANDLE_HIT_TARGET - called when spell hits it's target from spell target map
*Correctly implement SPELL_EFFECT_TRIGGER_SPELL, SPELL_EFFECT_TRIGGER_SPELL_WITH_VALUE, SPELL_EFFECT_TRIGGER_MISSILE_SPELL_WITH_VALUE, SPELL_EFFECT_TRIGGER_MISSILE_SPELL
*Remove spell system hacks which became obsolete with this commit
Core/SpellScripts:
add OnEffectLaunch, OnEffectLaunchTarget, OnEffectHit, OnEffectHitTarget hooks for new effect handle modes and remove OnEffect hook.
A generic rule of thumb how to update your scripts (will work for nearly all cases) for spell system noobs:
if your spell script used GetHitXXXX function, you need to use OnEffectHitTarget, otherwise use
OnEffectHit
*SpellEntry is now SpellInfo
*GetSpellProto is now GetSpellInfo
*SpellEntry::Effect*[effIndex] is now avalible under SpellInfo.Effects[effIndex].*
*sSpellStore.LookupEntry is no longer valid, use sSpellMgr->GetSpellInfo()
*SpellFunctions from SpellMgr.h like DoSpellStuff(spellId) are now: spellInfo->DoStuff()
*SpellMgr::CalculateEffectValue and similar functions are now avalible in SpellEffectInfo class.
*GET_SPELL macro is removed, code which used it is moved to SpellMgr::LoadDbcDataCorrections
*code which affected dbc data in SpellMgr::LoadSpellCustomAttr is now moved to LoadDbcDataCorrections
