Getting an exception in gendarme while analyzing a c# application using sonar

[vishnu]

Today when I analyzed a C# application (source code size above 20
mb).I am getting an exception as shown below

I am using sonar 2.12

I tried with maven and as well as with simple java runner

When I searched for similar exception in web I could n’t able find
valid reason for this issue.

Please help me out in resolving this issue

[Alik Kurdyukov]

Hi,

I have exactly the same exception. And the problem has something to
relation with COM library connection. I just turned off Gendarme from
sonar build. I'll try to investigate the problem if I build Gandarme.

This stack trace seems to indicate that you have a method with the
HasBody flag, but which doesn't have any Instruction.

Could you verify that this assumption is true?

I'll fix gendarme to not crash on this anyway.

[Alik Kurdyukov]

Hey,

I'm not sure I understand what's HasBody flag for methods. How can I check the assumption?

 

The assembly that crashed Gendarme includes 'native' code with ".custom" marks on methods. ILDASM show no disassemblies for them. For ex:

.class interface public abstract auto ansi import P2ClientGateMTA.IP2BLMessage

{

  .custom instance void [mscorlib]System.Runtime.InteropServices.TypeIdentifierAttribute::.ctor() = ( 01 00 00 00 ) 

  .custom instance void [mscorlib]System.Runtime.InteropServices.GuidAttribute::.ctor(string) = ( 01 00 24 41 38 35 42 43 37 41 33 2D 39 43 45 34   // ..$A85BC7A3-9CE4

                                                                                                  2D 34 32 39 45 2D 41 33 37 30 2D 35 38 37 35 44   // -429E-A370-5875D

                                                                                                  45 46 45 42 33 45 39 00 00 )                      // EFEB3E9..

  .custom instance void [mscorlib]System.Runtime.CompilerServices.CompilerGeneratedAttribute::.ctor() = ( 01 00 00 00 ) 

} // end of class P2ClientGateMTA.IP2BLMessage

You can run on your assembly a piece of code using Cecil like:

var module = ModuleDefinition.ReadModule("MyAssembly.dll");
foreach (var method in module.GetTypes().SelectMany(t =>
t.Methods).Where(m => m.HasBody && m.Body.Instructions.Count == 0)) {
Console.WriteLine ("Method with empty body: {0}", method);
}

And you'll have the names of actual methods with empty bodies.

[Alik Kurdyukov]

Thank you for code sample. For my assembly it gives:

Method with empty body: System.Void P2ClientGateMTA.IP2Connection::_VtblGap1_1()

Method with empty body: System.Void P2ClientGateMTA.IP2Connection::_VtblGap2_5()

Method with empty body: System.Void P2ClientGateMTA.IP2Connection::_VtblGap3_2()

Method with empty body: System.Void P2ClientGateMTA.IP2Connection::_VtblGap4_2()

Method with empty body: System.Void P2ClientGateMTA.IP2TableSet::_VtblGap1_4()

Method with empty body: System.Void P2ClientGateMTA.IP2TableSet::_VtblGap2_5()

Method with empty body: System.Void P2ClientGateMTA.IP2DataStreamEvents_Event::_VtblGap1_2()

Method with empty body: System.Void P2ClientGateMTA.IP2DataStreamEvents_Event::_VtblGap2_4()

Method with empty body: System.Void P2ClientGateMTA.IP2BLMessage::_VtblGap1_3()

Method with empty body: System.Void P2ClientGateMTA.IP2BLMessage::_VtblGap2_3()

Method with empty body: System.Void P2ClientGateMTA.IP2DataStreamEvents::_VtblGap1_1()

Method with empty body: System.Void P2ClientGateMTA.IP2DataStreamEvents::_VtblGap2_2()

BTW, I can give you binaries for P2ClientGateMTA assembly. Can it be of any help?

I see,

This is a Microsoft C# compiler bug:

https://connect.microsoft.com/VisualStudio/feedback/details/595412/bug-in-nopia-emission-of-vtblgap-methods

They emit managed methods which claim to be managed but are actually
implemented by the runtime. Not that they care a lot.

I committed a fix to gendarme
(1fbb7ea90bbb96d2d28f9567ec7dee8dc735cfc7), you can either build
gendarme yourself or have the sonar guys cherry-pick this fix.

Jb,

Thank you for hotfixing the problem. Do you have any dates for next Gendarme release?

Hello Alik,

Gendarme official releases occurs at the same time as Mono releases.
The beta cycle for 2.11 should start soon - but we're a few months
away from a stable 2.12.

Jb,

 

I am running into similar problems like Alik posted earlier. I downloaded the new 2.11  version of gendarme (gendarme-2.11-snapshot-20110305-win32-setup), but the problem is still there. Wondering if your hot fix has been included into new 2.11 version release.

 

BTW, I am totally new to using sonar .NET plugin, can you point me to where to get your a fix to gendarme
(1fbb7ea90bbb96d2d28f9567ec7dee8dc735cfc7)?

 

Thanks a lot for your help.

 

Ty

I'm running in to this too, here is a link to the commit Jb made:  https://www.ohloh.net/p/gendarme/commits/163580935 (couldn't get Google to find it from the UID).

I'll keep an eye out for news too.
