[jira] [Updated] (LOG4NET-484) System.ObjectDisposedException with
FileAppender+InterProcessLock
[ https://issues.apache.org/jira/browse/LOG4NET-484?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
NN updated LOG4NET-484:
-----------------------
Description:
Configure lockingModel for InterProcessLock with RollingFileAppender.
app.config:
```
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="test.log" />
<encoding value="utf-8" />
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="10"/>
<maximumFileSize value="1"/>
<staticLogFileName value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d [%t] %-5p %c{2} - %m%n"/>
</layout>
<lockingModel type="log4net.Appender.FileAppender+InterProcessLock" />
</appender>
<root>
<level value="INFO"/>
<appender-ref ref="RollingFileAppender"/>
</root>
</log4net>
</configuration>
```
Make a log with roll :
```
using log4net;
namespace ConsoleApplication131
{
class Program
{
static void Main(string[] args)
{
var log = LogManager.GetLogger(typeof(Program));
log.Info("A");
log.Info("A");
}
}
}
```
You get this one roll:
log4net:ERROR Failed to Close appender [RollingFileAppender]
System.ObjectDisposedException: Safe handle has been closed
at System.Threading.WaitHandle.WaitOneNative(SafeWaitHandle waitHandle, UInt3
2 millisecondsTimeout, Boolean hasThreadAffinity, Boolean exitContext)

was:
Configure lockingModel for InterProcessLock with RollingFileAppender.
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
...
<lockingModel type="log4net.Appender.FileAppender+InterProcessLock" />
..
</appender>
Write a lot of logs for instance:
const int N = 1000 * 200;
for (var i = 0;i < N; i++) m_log.Info("A");
When finilizers are called at the end of the program there is an exception:
