Here's a failing test case for the problem you described. The
StringAppender has a value of "(null)" when it should have the string
representation of today's date.
A similiar test case that launches the thread via the ThreadPool:
ThreadPool.QueueUserWorkItem(
new WaitCallback(ExecuteBackgroundThreadPool), null);
also fails.
The TestThreadPropertiesPattern test from
log4net.Tests.Context.ThreadContextTest passes when the property is
added from the same thread.
In my ASP.Net applications, I store the user's identification
information during Application_AuthenticateRequest in the
ThreadContext(?) and all my appenders have access to it.
I'll look around some more...
[Test]
public void TestBackgroundThreadContextProperty()
{
StringAppender stringAppender = new StringAppender();
stringAppender.Layout =
new PatternLayout("%property{DateTimeTodayToString}");
ILoggerRepository rep =
LogManager.CreateRepository("BackgroundThreadRepository");
BasicConfigurator.Configure(rep, stringAppender);
Thread thread = new Thread(new ThreadStart(ExecuteBackgroundThread));
thread.Start();
Thread.CurrentThread.Join(2000);
}
private void ExecuteBackgroundThread()
{
ILog log = LogManager.GetLogger(
"BackgroundThreadRepository",
"ExecuteBackgroundThread");
log.Info("TestMessage");
ThreadContext.Properties["DateTimeTodayToString"] =
DateTime.Today.ToString();
Repository.Hierarchy.Hierarchy hierarchyLoggingRepository =
(Repository.Hierarchy.Hierarchy)log.Logger.Repository;
StringAppender stringAppender =
(StringAppender)hierarchyLoggingRepository.Root.Appenders[0];
Assert.AreEqual(DateTime.Today.ToString(),
stringAppender.GetString());
}
