Description kochizufan 2014-05-06 23:16:16 UTC
Hello,

I compile couchbase-lite-net for iOS and Android. 
And when I writing test-code, there are inaccessible bug which is not occured in Android but occured in iOS.

Situation is,


In logic code, Couchbase.Lite.Database includes internal property.

#### Code ####
namespace Couchbase.Lite 
{
    public partial class Database 
    {    
        ...

        internal LruCache<String, Document>             DocumentCache { get; set; }

        ...        
    }
}
#### Code ####

And, I wrote testcase like this:

#### Test ####
namespace Couchbase.Lite
{
    [TestFixture]
    public class TestsSample
    {
        ...

        [Test]
        public void TestCreateDocument()
        {
            ...

            var db = manager.GetExistingDatabase(DefaultTestDb); //<= This is Database class.

            ...

            db.DocumentCache.EvictAll(); //<= Not error in Android, but in iOS.

            ...

        }
    }
}
#### Test ####

This testcase pass in Android, but not in iOS, because of protection level issue.

Error says:

Error CS0122: `Couchbase.Lite.Database.DocumentCache.get' is inaccessible due to its protection level (CS0122) (Couchbase.Lite.Touch.Tests)
Both Logic and test codes are exactly same in both Android and iOS.

Is this a bug? 
Or, this is based on difference of JIT and AOT?

This is not related to AOT/JIT, because the error happens during compilation of the C# source code (the AOT/JIT are only used at runtime).

Is all the code in the same project, or are they in different projects?

In general projects should not be able to access internal members of other projects, but this can be overcome by using the InternalsVisibleTo attribute - however it is required that assemblies are properly signed when using the InternalsVisibleTo attribute, otherwise you'll get precisely the error you're seeing.

So my initial guess would be that the iOS projects/assemblies aren't properly signed.
Comment 2 kochizufan 2014-05-07 10:38:51 UTC
Thank you for replying my report,

Yes, I devide Logic project and Test project, like this:

Android Logic:
  Project name: Couchbase.Lite.Android
  Namespace: Couchbase.Lite
Android Test:
  Project name: Couchbase.Lite.Droid.Tests
  NameSpace: Couchbase.Lite.Tests

iOS Logic:
  Project name: Couchbase.Lite.Touch
  Namespace: Couchbase.Lite
iOS Test:
  Project name: Couchbase.Lite.Touch.Tests
  NameSpace: Couchbase.Lite.Tests


But, in both Android and iOS Logic project, AssemplyInfo.cs contains

[assembly: InternalsVisibleTo("Couchbase.Lite.Tests")]

setting.
This setting does not contain PublicKey infomation, so I think Tests don't need proper sign..
Is it misunderstanding?

I can send zipped whole project or point git repository, if need.

Regards,

Ko-hei

Sorry, I forgot that iOS executable's assembly name cannot include ".".

I change 

[assembly: InternalsVisibleTo("Couchbase.Lite.Tests")]

to

[assembly: InternalsVisibleTo("CouchbaseLiteTests")]

in iOS, it works...
Comment 4 Rolf Bjarne Kvinge [MSFT] 2014-05-08 07:35:54 UTC
Great that you figured it out!

I'll close the bug report then.
