Webroar not able to deploy a specific app

#21

Hi,

My WebROaR is able to deploy standard Rails Applications but there is a specific application which has some plugins installed which its not able to deploy. The Rails App runs fine when run with WebRick or mongrel both in production and development environment.

The error log shows the following.

This doesn't happen when I create the app in a fresh install of WebROaR, But whenever I do a service webroar restart this bug appears.

Thanks for taking time to report the issue.

From the log, we felt it could be Hobo application creating this problem, but sample Hobo application is running perfectly fine at our end.

Could you please give us following details to debug the issue throughly?
1. Rails plugins name which are likely be creating the issue
2. Operating System
3. Ruby version

Thanks for the reply.

As I mentioned earlier the error doesn't appear when WebROaR is freshly installed. I am able to run the Hobo application at-ease. But once I do a service webroar restart the error starts appearing.

The app runs perfectly fine on mongrel as well.

Here are the details
1. Rails Plugins: There are no plugins beyond the standard Hobo and its dependencies.
2. Operating System/Kernel: Ubuntu 9.04 Server
  Linux host 2.6.18.8-xen #1 SMP Fri Oct 16 21:58:15 EDT 2009 x86_64 GNU/Linux
3. Ruby Version:
  ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]

Sorry, my bad, service webroar restart reproduced issue for me.

From the man pages of service command,

service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /.

...

...

LANG and TERM are the only environment variables passed to the init scripts.

The application loading is getting failed because, Rails generator is looking into home directory to locate the generators, and for that it is using HOME environment variable.

Any specific reason behind restarting server using service command?

You could use webroar restart or /etc/init.d/webroar restart to restart the server preserving the environment variables. Please let us know how it goes for you.
