[Mono-list] Weird crash with Remoting, native code exception
Hello guys, I am running a client-server application with a remoting server operating under mono (1.1.15 compiled from source, running on SuSE 9.1 - for the records). The client (SWF) application gets a reference to the server's CAO-remoted object and everything runs just fine. However, one server function attempts to call a method of a (Singleton) remoted object of another server (same machine, in this case). The object reference on that latter server is acquired via Activator.GetObject and this *seems* to work. (I can get the value of a remote string property). However, calling the method I intend to call crashes my (calling) server. The Singleton provider keeps running (or seems to be). Usually using mono-service together with Robert Jordan's SuSE-compatible start script, I tried to run mono-service from the console with debugging symbols and all. When it comes to the crash, I see the following output: = Got a SIGSEGV while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. = Stacktrace: Native stacktrace: mono(mono_handle_native_sigsegv+0x81) [0x8143c41] mono [0x8114a97] [0xe440] [0x41ff23cf] [0x41fef9de] [0x40d4c5c8] [0x40ceb551] mono [0x8131001] mono(mono_runtime_invoke+0x1b) [0x80cc97b] mono(mono_runtime_delegate_invoke+0x2d) [0x80ccc3d] mono [0x80ae9e3] mono [0x80f4804] mono [0x810b5fb] /lib/tls/libpthread.so.0 [0x400be9dd] /lib/tls/libc.so.6(__clone+0x5a) [0x401aaffa] Aborted Furthermore, this behaviour doesn't always occur. The two other chances are that it (a) just works and (b) returns with a handled exception in the calling server's code (NullReferenceException). AS I haven't found out why it does what and when, I'd appreciate hints on where to look further to track this down. I figured it could be related to: - threading? (huh, bad luck given my current threading-skillset ;-) - registering the remote object. However, in all cases, the called server's appropriate port is occupied when the program runs - mono-service related issues (my call is: mono [--debug] -l:/var/run/servicelock.pid -m:servicename -d:servicedir serviceassembly --- and seems to work fine for both programs) Many thanks for your assistance!

Re: [Mono-list] Config file for dll
Hello Peter,
I use that same code to read assembly settings and found it best to use
the Assembly.Location property. I use the following code with both .NET
and mono:
string cfgFile = asm.Location + .config;
const string nodeName = appSettings;
Note that I also changed the node name from assemblySettings to the
standard appSettings. I know this is semantically incorrect as the DLL
is not the app, but it makes interchanging config files a lot easier
and editing is less error-prone.
Best regards,
Helge
Bradley, Peter schrieb am 07.02.2006 12:06:
Hi,
I’ve tried to post on this before, but never managed to get below the
size limit. So this is a change of tactic J
The problem is that I would like to keep the connection string for the
application’s db connectivity in a configuration file instead of hard
coding it. However, since I’m making the db connection from a dll
rather than an exe file I can’t use a normal App.config file. What I
would like to do is to use the AssemblySettings class that can be
found at:
http://www.bearcanyon.com/dotnet/#AssemblySettings
This allows the settings to be accessed like this:
// AssemblySettings usage:
//
// If you know the keys you're after, the following is probably
// the most convenient:
//
// AssemblySettings settings = new AssemblySettings();
// string someSetting1 = settings[someKey1];
// string someSetting2 = settings[someKey2];
This works in .NET on Windows, but not in Mono on Linux. When I deploy
the project to my Linux server and try to run the db connectivity
code, I get an error saying that the table cannot be read. I’m certain
this is because the connection string is not being read from the
config file because if I hard code the connection string into the
program instead of calling AssemblySettings, everything works just
fine. In other words, I think the config file is not found under Mono.
Looking at the AssemblySettings code, I think the problem is here:
public static IDictionary GetConfig( Assembly asm )
{
// Open and parse configuration file for specified
// assembly, returning collection to caller for future
// use outside of this class.
//
try
{
string cfgFile = asm.CodeBase + .config;
const string nodeName = assemblySettings;
XmlDocument doc = new XmlDocument();
doc.Load(new XmlTextReader(cfgFile));
XmlNodeList nodes = doc.GetElementsByTagName(nodeName);
foreach( XmlNode node in nodes )
{
if( node.LocalName == nodeName )
{
DictionarySectionHandler handler = new DictionarySectionHandler();
return (IDictionary)handler.Create(null, null, node);
}
}
}
catch (Exception ex)
{
string s = ex.Message;
}
return(null);
}
In Windows, the variable cfgFile is set to (for example)
MyAssembly.dll.config and then the XmlTextReader object reads the XML
file (the config file) in the folder of the dll’s calling assembly,
which would be the folder of the executable assembly that links to the
dll, under normal circumstances (assuming the assembly is not in the
GAC). I don’t plan to put the assembly in the GAC.
Is it possible that Mono is looking in a different place? Is there
some code I need to add to ensure that Mono will look in some specific
place?
Many thanks
Peter

[Mono-list] Remoting and firewalls
Hello mono folks, I am writing a service that offers a remoted object on either Windows or mono/Linux. While this indeed works great on mono, my solution uses the commercial GenuineChannels product on Windows that offers a bidirectional TcpChannel implementation. This allows to get around firewalls and NAT routers but unfortunately only runs on Windows (offering lots of additional features like security sessions, impersonation, direct exchange etc. which aren't used in my case).. I'm now looking at something similar for mono, or any other solution to get connected to the server. My research so far brought up the following, most of it from a discussion on this list about two years ago: - SSH tunneling to the server might be an option. What I tried was forwarding the server port to my client machine which allowed me to connect to a singleton. Then a method is called and a CAO returned, only that the new object's URI points to the real server's name instead of localhost again. (I used this to allow for an interface-based design). - Anyway, requiring an SSH connection doesn't seem the most intuitive for the end user... Also I couldn't figure out what to do for the callback channel (I use the new TcpChannel(0) constructor for an arbitrary callback port). I'd be happy to learn about possible hints or solutions for this problem or pointers for helpful reading.

Re: [Mono-list] Re: Remoting: SocketException on Windows client when server runs on Linux (certain machines)
Oh really! That was it, a wrong URI that the client couldn't ever reach. Thanks Rob for showing the way to find this out! Best regards, Helge Robert Jordan schrieb: Hi, There's basically a client/server situation with the client being a Windows application calling a server via TcpChannel on Linux/mono. The remoted singleton object has a method that returns a class that acts like a CAO. This works very well with my SuSE 9.1 based test environment. For some reason, it does not work with the server running on a freshly installed SuSE Linux Enterprise Server 9 (additionally installed pkg-config and mono-complete RPMs there). My Windows client gets the proxy instances of the remote objects, but the first call to the actual worker object fails - with a SocketException, telling me the destination host is unreachable!? Huh! The problem occur when client and server don't agree upon a common host name, for example when the server has a hostname w/out a valid DNS entry. Try to find out the URI by calling RemotingServices.GetObjectUri() on the returned object. Does it return something that your client is able to connect to? If not, your server is probably missconfigured. You may also try to apply some remoting config settings in the app.config of your server, especially bindTo and machineName.

[Mono-list] Services, daemons
Hello list, I have a core app that is usually embedded into a Windows service and, alternatively, into a console program for debugging. As the console program runs fine on mono (on SuSE 9.1, in my case), I'm looking into running it as a Linux daemon or other form of permanent, auto-starting system. For this it would be needed to replace two Windows-related mechanisms: ServiceProcess and EventLog. The logging part seems easy as I can switch to logging into a file, or look into the syslog functions. Are there any recommendations for the daemon/service part? Can I make use of ServiceProcess at all - I guess not? Is there a must-read available anywhere to clear things up? I believe this is also heavily distro-specific?

[Mono-list] InvalidOperationException when using a DataAdapter's Update method (mono, npgsql)
Hello folks, I am seeing a weird InvalidOperationException being thrown when I use a (Npgsql)DataAdapter's update method in a particular setting. As I'm unsure where the error lies, I'm looking for help here before filing any bugs. Part of the problem might be that my db related stuff is coded against the generic interfaces for the sake of db engine independence. The error itself occurs on mono (1.1.7 in my case), regardless of whether used on Windows or Linux, when using Npgsql as the database provider. It does not occur on Windows with MS's framework 1.1 and Npgsql. It does also not occur on mono/MS.NET with their respective System.Data.SqlClient implementations. Now here goes... The unrelated parts of an example program are left out. The following expects a connection conn to opened to a certain database with a table table1 with an id, col1 of type varchar(50) and col2 of type integer. //Write back changes into database IDbCommand cmdUpdate = new NpgsqlCommand(UPDATE table1 SET col1=:p1, col2=:p2 WHERE id= + id.ToString()); cmdUpdate.Parameters.Add( new NpgsqlParameter(p1, NpgsqlTypes.NpgsqlDbType.Varchar, 0, col1) ); cmdUpdate.Parameters.Add( new NpgsqlParameter(p2, NpgsqlTypes.NpgsqlDbType.Integer, 0, col2) ); cmdUpdate.Connection = conn; da = new NpgsqlDataAdapter(); da.UpdateCommand = cmdUpdate; da.TableMappings.Add(Table, table1); int affectedRows = da.Update( ds ); The error that is raised on the Update command is the following: Unhandled Exception: System.InvalidOperationException: Cannot read data.

Re: [Mono-list] True C# vs Mono-C# Documentation?
Lennie, from my (mostly) spectator's position on this list, I felt that I needed to jump in here to say that Mono *is* True C#... :-) Depending on the nature of your application, you might or might not run into problems running your code with Mono. At the current stage of development of the framework (which is what counts here, not C# itself), you will be able get up and running quickly with existing ASP.NET web applications and server based/console applications. Problems will arise if you (a) have System.Windows.Forms dependant GUI apps and/or (b) need to call COM components or (c) need to P/Invoke with Windows platform specific functions. If you rely on a database (which is much likely MS SQL Server on Windows), you will need to convert to a DBMS that runs on Linux as well for a true conversion to that platform (e.g. MySQL, PostgreSQL). It makes more sense to compare the problem domains and technologies you are using to what mono is currently offering in its framework.
