[ruby-core:43211] [ruby-trunk - Bug #5618] Exceptions cause DRb connection to be closed

----------------------------------------
Bug #5618: Exceptions cause DRb connection to be closed
https://bugs.ruby-lang.org/issues/5618

Author: Lars Christensen
Status: Open
Priority: Normal
Assignee: Masatoshi Seki
Category: lib
Target version: 
ruby -v: ruby 1.9.3p0 (2011-10-30) [i386-mingw32]


If an exception is thrown in a DRb server of a class that is not defined in the client process, the DRb connection is closed abrubtly. In Ruby 1.8, the exception was translated to an instance generic exception class (DRb::DRbRemoteError).

Steps to reproduce:

1. Start DRb client+server
2. Throw exception of custom class in server (class not defined in client script).

Observed behaviour:

3. Client raises DRb::DRbConnError because connection is closed - used to be generic error.

Expected behaviour:

3. Client raises DRb::DRbRemoteError, and preserves full stack trace from server.

Attached is server/client script showing the problem.

Here is the stack trace of the client:
