Description Martin Costello 2015-08-28 09:59:50 UTC
Using the latest Mono 4.2.0 alpha release, and unit test that tests round-trip serialization of a custom exception type that was working previously is now failing.

https://travis-ci.org/experiandataquality/electronicupdates/jobs/74706434

The specific error message is:

"System.ExecutionEngineException : Failed to create shadow copy of sibling data (CopyFile).
      Stack Trace:
            at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (System.Reflection.MonoMethod,object,object[],System.Exception&)
         <filename unknown>(0,0): at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture)"
Comment 1 Martin Costello 2015-08-28 10:00:25 UTC
The specific Mono version for this build was:

"Mono JIT compiler version 4.2.0 (explicit/a224653 Mon Aug 17 12:38:55 EDT 2015)"
Comment 2 Marek Safar 2015-08-31 04:22:56 UTC
The exception comes from shadow copying of some file which I am not sure how can be related to custom exception.

Could you make a repro for us to investigate what is actually failing
Comment 3 Rodrigo Kumpera 2015-08-31 11:21:14 UTC
Please provide test instructions on how to reproduce this bug.
Comment 4 Martin Costello 2015-09-01 04:41:34 UTC
To replicate, you can do the following:

  * Install Mono 4.2.0 Alpha on OS X;
  * Clone https://github.com/martincostello/electronicupdates as of commit d70a8eebcdc23183b67c29a6d0d488d2a10132b8;
  * Run ./src/CSharp/MetadataWebApi/build.sh and observe the outcome of the xUnit test 'MetadataApiException_Constructor_For_Serialization_Can_Be_Serialized'.
Comment 5 Martin Costello 2015-09-01 04:49:03 UTC
There's some chatter on a GitHub issue (https://github.com/xunit/xunit/issues/158) which I was seeing whether it was fixed that led me to find this bug which has moved to talking about errors related to shadow copies with AppDomains. Could it be the same root issue?
Comment 6 Marek Safar 2015-09-21 07:37:32 UTC
I cannot reproduce it locally. My output

I've just re-built the same job in Travis CI and the problem appears to have gone away:
