[LOG4NET-519] Number of RollBackups files extremely increases

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 1.2.15

Description

We have defined LogManager with repositories. In repositories are the RollingFileAppenders. For each RollingFileAppender are defined values:

C#, init value settings

        AppendToFile = true;
        RollingStyle = RollingFileAppender.RollingMode.Size;
        MaxSizeRollBackups = maxFileCount;
        MaximumFileSize = maxFileSize;

It works without problems and number of RollBackups files is equal to MaxSizeRollBackups. If values of MaxSizeRollBackups and MaximumFileSize are runtime changed, the MaxSizeRollBackups is ignored, RollBackups files are not deleted and number of RollBackups files extremely increases. There can be more than 1500 files!!!

RollingFileAppender change in our C# code:

C#, runtime value changing

  foreach(var v in LogManager.GetRepository(CreateRepositoryName(id)).GetAppenders())
  {
	if(v is RollingFileAppender)
	{
	  RollingFileAppender roll = v as RollingFileAppender;
	  if (roll.MaximumFileSize != filesize)
	  {
		roll.MaximumFileSize = filesize;
	  }
	  if (roll.MaxSizeRollBackups != filecount)
	  {
		roll.MaxSizeRollBackups = filecount;
	  }
	}
  }

Part of log4net logging. There are 22 RollBackups, but maxSizeRollBackups is set to 2. The value of maxSizeRollBackups is ignored.
