SSH Agent forwarding does not work with jRuby (which lets capistrano ssh-deployments fail)

  • Affects Version/s: None
  • Fix Version/s: JRuby 1.7.0.pre2
  • Component/s: OpenSSL

Description

Unfortunately, the agent forwarding option seems to fail using jRuby.
Capistrano deployments won't work if you're using ssh transport for git in combination with agent forwarding.
The connection simply hangs.

Attached you'll find a simple case which works in MRI and hangs in jRuby.

Best,

Tobias

IMHO this bug is even critical because it makes deploying git apps via capistrano almost impossible.
How are you guys doing this and why did nobody ever realize it?

I've encountered this issue as well. Deploying with the ssh_forward option turned on for Capistrano causes the deployment to hang. Using a non-JRuby (1.9.2 MRI) it works fine. Turning off ssh_forward doesn't hang, but then doesn't really do what I need to for deployments (since we rely on the ssh_forward stuff).

Thanks for the dump. The net/ssh client seems to be waiting for a response from the server.

Can someone run JRuby with -d and -Xbacktrace.style=raw to see more detail about what's happening inside?

Removing me from Assignee because I don't have an environment now. I would be able to take this again when logs/traces are provided.

Here's a trace running JRuby 1.6.7 in 1.9 mode with Capistrano 2.12.0. I have the same problem with using 1.7.0-dev.

I think JRUBY-5868 may be related as well.
