Description of Problem:
I try to use to log4net RemotingAppender with mono (in order to create a
centralised log server for all our web applications)


Steps to reproduce the problem:
1. Create a simple RemotingAppender 
    <appender name="RemotingAppender"
type="log4net.Appender.RemotingAppender" >
	    <sink value="tcp://localhost:1234/LoggingSink" />
	    <lossy value="false" />
	    <bufferSize value="1" />
	    <onlyFixPartialEventData value="true" />
	</appender>
2. Create the server
3. 

Actual Results:

log4net:ERROR XmlHierarchyConfigurator: Could not create Appender
[RemotingAppen
der] of type [log4net.Appender.RemotingAppender]. Reported error follows.
System.Runtime.Remoting.RemotingException: Cannot create channel sink to
connect
 to URL tcp://localhost:1234/LoggingSink. An appropriate channel has

Expected Results:


How often does this happen? 
always

Additional Information:
it works well on MS.NET 1.1 it should works too with mono...
See the attached monodevelop solution test case!

the error is : Cannot create channel sink to connect to URL

Hubert, if you have the sources, open the file which contains
the class RemotingAppender and replace ActivateOptions ()
with this:

public override void ActivateOptions()
{
    base.ActivateOptions();
    m_sinkObj = (IRemoteLoggingSink)
Activator.GetObject(typeof(IRemoteLoggingSink), m_sinkUrl);
}

 
The hashtable used by log4net as "channelData" is apparently
incompatible with mono:

    IDictionary state = new Hashtable();
    state["typeFilterLevel"] = "Full";
    m_sinkObj = (IRemoteLoggingSink) 
        Activator.GetObject(typeof(IRemoteLoggingSink), m_sinkUrl, state);

I'm uncertain if this is correct even on MS.NET, but it
seems to work there.

Am looking at this.

We need the old hack (see comment) only when channelData is a
IChannelDataStore, otherwise there is no way for the channel
to obtain the URI.

The patch looks ok to me.



---- Additional Comments From robertj@gmx.net 2007-06-05 16:06:14 MST ----

Fixed in SVN r78667.

Thanks a lot for the fix, it works well for me

Could this patch be backported to the mono 1.2.4 branch... I've seen
that is trivial, and with this i could get log4net working on our
production server...
