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:
