C4100: 'x' : unreferenced formal parameter
C4310: cast truncates constant value
C4389: '==' : signed/unsigned mismatch
C4668: 'x' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
C4701: potentially uninitialized local variable 'x' used
C4826: Conversion from 'HMODULE' to 'DWORD64' is sign-extended. This may cause unexpected runtime behavior.
C6067: Parameter '3' in call to 'sprintf' must be the address of the string
C6387: 'argument 1' might be '0': this does not adhere to the specification for the function 'CloseHandle'
- Restored old CharDump (LOG_FILTER_PLAYER_DUMP) but disabled by default.
- "%s" is now used to set dynamic file names, only used by GM commands and Player dump
Changed multiple lines to a simple format:
- Logger.name=Type,LogLevel,Flags,AppenderList
- Appender.name=Type,LogLevel,Flags,optional1,optional2
* Type = File: optional1 = File name, optiona2 = Mode
* Type = Console: optional1 = Colors
Created a default set of loggers and appenders.
- Root logger defaults to Error, that means you will see nothing on console by default (not even loading)
- You need to add the loggers to Loggers options if you want to enable them, otherwise Root logger will be used for all types
Restored outSQLDriver (LOG_FILTER_SQL_DRIVER), outSQLDev (LOG_FILTER_SQL_DEV), outArena (LOG_FILTER_ARENA) and outChar (LOG_FILTER_CHARACTER) functionality by creating new types (LOG_FILTER_CHARACTER is a rename of LOG_FILTER_DELETE.
Note: You need to update your config file... again (yeah sorry... trying to make it simpler)
- Appender config option .Timestamp and .Backup became obsolete
- New Appender config option .Flags added
Appender Console prefixes Log Level and Log Filter Type to the logged text as default
Appender File prefixes Timestamp, Log Level and Log Filter Type to the logged text as default
