Subject [jira] [Created] (LOG4NET-560) UnauthorizedAccessException in RollingFileAppender when acquiring a mutex
Date Thu, 30 Mar 2017 07:58:41 GMT
Erik Källén created LOG4NET-560:

             Summary: UnauthorizedAccessException in RollingFileAppender when acquiring a
                 Key: LOG4NET-560
                 URL: https://issues.apache.org/jira/browse/LOG4NET-560
             Project: Log4net
          Issue Type: Bug
            Reporter: Erik Källén

I have a setup where I want two processes, running as different user accounts to log to the
same file.

I have set up the file permissions so they work, but the second process that starts cannot
perform the logging due to this error:

log4net:ERROR Could not create Appender [myAppender] of type [log4net.Appender.RollingFileAppender].
Reported error follows.
System.UnauthorizedAccessException: Access to the path 'E__Log_MyLog.log' is denied.
   at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
   at System.Threading.Mutex.MutexTryCodeHelper.MutexTryCode(Object userData)
   at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode
code, CleanupCode backoutCode, Object userData)
   at System.Threading.Mutex.CreateMutexWithGuaranteedCleanup(Boolean initiallyOwned, String
name, Boolean& createdNew, SECURITY_ATTRIBUTES secAttrs)
   at System.Threading.Mutex..ctor(Boolean initiallyOwned, String name, Boolean& createdNew,
MutexSecurity mutexSecurity)
   at System.Threading.Mutex..ctor(Boolean initiallyOwned, String name)
   at log4net.Appender.RollingFileAppender.ActivateOptions()
   at log4net.Repository.Hierarchy.XmlHierarchyConfigurator.ParseAppender(XmlElement appenderElement)

I think the mutex should be created with access for Everyone, and that would solve the problem.
