Frontend-GNOME: detect and report Mono <-> .NET incompatibility for remote engines (refs: #589)

Smuxi users running a smuxi-server on Mono and connecting from Windows using the
Microsoft .NET framework will lead to an user-unfriendly crash dialog like this:

Exception Type:
System.InvalidCastException
Exception Message:
Object must implement IConvertible.
Exception StackTrace:
Server stack trace:

The user has no hint how to proceed here. Since this is a known incompatibility
since Mono 2.10 [0], we detect this condition and hint the user how to fix it.

Are you using smuxi-server? If so, which side have you upgraded to 2.10.1?

Updated by Mirco Bauer 4779 days ago

For the record: smuxi-server on mono 2.6.7 and smuxi-frontend-gnome on mono 2.10.1 works for me

Updated by Carlo Kok 4778 days ago

server is: Mono JIT compiler version 2.10.1 (tarball Mon Apr 11 15:46:24 UTC 2011)

mono --version

gui runs on windows (not mono). It worked before I updated the server to 2.10

Have you installed Smuxi from source tarball or a binary package? Please check if it links .NET 2.0 by running:
monodis --assemblyref smuxi-server.exe

Installed from a binary package, I think the "Other "package.

So Mono 2.10.1 is no longer ABI (Remoting) compatible with .NET 3.5, that is very sad. I hope this will be fixed in Mono. Can you give Mono 2.10.2 a try?

There is no known workaround yet. Mono 2.10.x broke ABI compatibility with MS .NET when it comes to the System.Collections.Generic.Dictionary<K, V> type which Smuxi makes use of. We will need a fix in Mono for this issue.

Has this bug been reported upstream? If so, do you have a link to the case? I'm having the same issue in my code and would like to look into fixing it.

I never experienced this issue with Mono 2.10.8 so I think I can assume the issue is no longer present

This issue only becomes visible when the smuxi-server runs on Mono 2.10 and the frontend on Microsoft .NET

Updated by Mirco Bauer 3361 days ago

The only known workaround is to use Mono on Windows

Most people start to only see this issue when they add a Twitter account for some reason. Here is such sample:

System.InvalidCastException

The real fix of this issue will come with switching to a new RPC system like REST. HTTP/JSON/REST does not rely on binary serialization like .NET remoting currently does.

Smuxi is now detecting this issue and shows a dialog with a link to resolve the issue instead of crashing.
