PartialMock throws BadImageFormatException

[Kenneth Xu]

Hi,

Here is the test code to reproduce it.
public abstract class MyClass
{
public virtual void Foo<T>(List<T>[] action) { }

/* ... */
}

[TestFixture] public class MyTest
{
[Test] public void MyTestCase()
{
var mockery = new MockRepository();
var mock = mockery.PartialMock<MyClass>();
mockery.ReplayAll();
mock.Foo<string>(null);
}
}

Am I doing anything wrong here or this is a bug? from Castle dynamic proxy?

Thanks,
Kenneth

[Tim Barcz]

Though I don't have a fix for you the problem comes in with DP and the "List<string>[] action" param.  I don't know all the details but at one time (and maybe still exists) there was some goofiness around DP and generics.  Playing with your code I found the following (draw your own conclusions)

The test passes when:

• I get ride of the array as a param - public virtual void Foo<T>(List<T> action) { }
  
• I make the method NOT generic - public virtual void Foo(IList<string> action) { }
  

It seems to be an issue with DP and generics, whether an array of lists (of type T) or making Foo a generic method.

I'll enlist some DP experts who can hopefully help.

Hi Tim,

Thanks for confirming this. What's what I guessed by looking at the
exception stacktrace. The code I posted was feigned. The real SUT is a
concurrent API for CLR2.0 under development. You can find the source
here: https://fisheye.springsource.org/browse/se-threading-net/trunk/src/Spring/Spring.Threading/Threading/Execution/AbstractExecutorService.cs?r=84#l471

I guess I'll need to write my own Fake for time being to complete the test.

Thanks,
Kenneth

Hi Tuna,

This seems to be worse. When I ran the test, RhinoMocks was able to
create the proxy object. It choked on the method call. With updated
DP, you cannot even instantiate it now.

Thanks for looking into this and trying on the latest DP. I appreciate it.

Cheers,
Kenneth

[Krzysztof Koźmic]

Tuna,

The cause of your error may be that there was a slight change that
fixed handling constructor parameters of some cases with class proxy.
Seems that RM relies on the buggy behavior, hence the error. I'm
reinstalling my VS and SDKs so I can't confirm, but it's very likely
that's the case.

Tuna & Kyzysztof,

Thank you both for jumping right on this.  Often people say they worry about OSS because of it's lack of commercial support.  Today was an example that blows that theory out of the water.  Two open source projects, RhinoMocks and Castle came together with three committers to help a "customer" of our respective frameworks.

Thank you both for you help and diligence to your projects, it's a pleasure working with you guys,

Tim

[Kenneth Xu]

And the "customer" is also a committer of another open source project :)

Thank you all!

Cheers,
Kenneth

[Tim Barcz]

Which project is that?

Tim

[Kenneth Xu]

Spring.Threading http://www.springsource.org/extensions/se-threading-net

- A concurrent API for .Net CLR 2.0
- Initially ported from Java's concurrent API but added many .Net
features. It offers more then .Net 4.0 Task Parallel Library does.
- In future, provide same functionality of .Net 4.0 Task Parallel
Library to CLR 2.0

Kenneth:

I fixed the issue we had in Castle, please get the latest binaries
http://www.castleproject.org:8090/viewLog.html?buildId=383&tab=artifacts&buildTypeId=bt6
and see if it fixed the issue for you. Unfortunatelly my PC went nuts
and I'm unable to compile Rhino and see for myself :/

Thanks Krzysztof. I'll compile Rhino myself when I get home tonight after work.

Will let you know.

[Kenneth Xu]

Hi Krzysztof,

I got connection timeout when downloading. Any idea?

Thanks,
Kenneth

[Tuna Toksoz]

now I'm back home, and i tried trunk of DP against trunk of RM.

and

your test is

passing!!!!

There are 2 failing tests,Tim & Krzysztof, the types of the some of the exceptions that were previously thrown are now changed.

Expected exception of type System.MissingMethodException, got System.ArgumentException (Can not instantiate proxy of class: Rhino.Mocks.Tests.MockingClassesTests+OverLoadedCtor.Could not find a constructor that would match given arguments:System.String

I believe ArgumentException is better as user provide constructor arguments and the constructor is there if argument is correct.
So this would require a little "test" change in RM.

Tuna and Krzysztof,

Thanks for the quick turn around. While the change did fix the
original issue. It failed again with a more complex method signature:

public virtual void
GenericMethodWithGenericOfGenericArgument<T>(IEnumerable<IComparer<T>>
compararers) { }

Attached patch adds two test cases to the PartailMockTest.

Tim, the patch is applicable to the latest trunk.

Yeap! Fabulous job, Krzysztof and Tuna. Will certainly report if I
find anything else. I guess the concurrent API is really stressing DP
and RM. In the mean time, I do have a feature request. Be able to
intercept the non-virtual interface implementation method. Below is an
example, can castle do something what MyProxy does?

public interface ICommon { void Foo(); }

public class ThirdParty : ICommon {
public void Foo() { Console.WriteLine("From 3rd Party."); }
/* other additional features */
}

public class MyProxy : ThirdParty, ICommon {
void ICommon.Foo() {
Console.WriteLine("From proxy.");
base.Foo();

ProxyWithTarget is composition based instead of inheritance based. Am
I right? If yes, then (proxy is ThirdParty) == false.

The advantage of inheritance based is to handle code like:

void Bar(ICommon common) {
ThirdParty tp = common as ThirdParty;
if (tp!=null) {
// do something optimization with tp that we cannot intercept, that's fine.
}
// do somethings else with common that we can intercept.
}

Oh I believe you can do that, with class proxy + additional interfaces.

Kenneth,

Currently you can't do this, but I think it's just an omission (as you
can read in this post
http://kozmic.pl/archive/2009/07/01/castle-dynamic-proxy-tutorial-part-xi-when-one-interface-is.aspx).

Technically however I can see no reason why this could not be done so
please add this to Castle' issue tracker and I think we'll be able to
fix it for v2.2.

You are trying to use x86 assembly on your x64 platform (don't you have x64?).
I think that in your main .net project there is a default setting Any CPU.

Change that to x86, then you will be able to run the project as 32bit
application.
Or find other dependent assemblies.

The issue with interfaces on class is fixed in Castle trunk. Take a
look here to read about limitations (which are a result of how CLR
works, not Dynamic Proxy): http://kozmic.pl/archive/2009/07/12/more-on-proxies-and-additional-interfaces.aspx

[Kenneth Xu]

Another great work done!

As to the limitation on explicit implementation. I believe there is a
way to overcome. Let me do some research. If I find any, I'll add
comment to your blog post.
