AppendToFile resets to False when log file rolled
Using log4net: 1.2.10.0
Found strange behavior in appendToFile property when RollingFileAppender
is used. If appendToFile=True in configuration and when daily roll event
fired, property append for the new file gets false. Internal debug is
enabled.
If you look you will find that: log4net: FileAppender: Opening file for
writing [C:\Applications\Starter\logs\info.log_04-02-2011] append [True]
(this is correct) and when file rolling happens new file created but
append gets false: log4net: FileAppender: Opening file for writing
[C:\Applications\Starter\logs\info.log_05-02-2011] append [False]. Is
this right behavior?
So according to SDK: If the value is set to false then the file will be
overwritten, if it is set to true then the file will be appended to. The
default value is true.
I tested it with setting time to 23:58 and executed my application,
waited for 3-5 minutes.
