Pavel Kilik created LOG4NET-519:
-----------------------------------
Summary: Number of RollBackups files extremely increases
Key: LOG4NET-519
URL: https://issues.apache.org/jira/browse/LOG4NET-519
Project: Log4net
Issue Type: Bug
Affects Versions: 1.2.15
Environment: Win 7
Reporter: Pavel Kilik
Priority: Minor
We have defined LogManager with repositories. In repositories are the
RollingFileAppenders. For each RollingFileAppender are defined values:
{code:title=C#, init value settings|borderStyle=solid}
AppendToFile = true;
RollingStyle = RollingFileAppender.RollingMode.Size;
MaxSizeRollBackups = maxFileCount;
MaximumFileSize = maxFileSize;
{code}
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:
{code:title=C#, runtime value changing|borderStyle=solid}
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;
}
}
}
{code}
Part of log4net logging. There are 22 RollBackups, but maxSizeRollBackups is
set to 2. The value of maxSizeRollBackups is ignored.
{code:title=log4net logging|borderStyle=solid}
log4net: rolling over count [2058]
log4net: maxSizeRollBackups [2]
log4net: curSizeRollBackups [22]
