Hi there,

I am using the acts\_as\_ferret plugin version 0.4.4 with rails 2.3.4 and  
am getting an error when try to start the Drb server.

The error appears to be that the unix\_daemon cannot open the pid file.  
However this only happens if I specify a config value:

pid\_file: log/ferret\_server.pid

in the ferret\_server.yml. If I do not then the default values from the  
ferret\_server.rb file are used and the Drb server starts.

The error output is a follows:

/home/yellowpinky/my\_project/vendor/plugins/acts\_as\_ferret/lib/unix\_daemon.rb:53:in  
`initialize': No such file or directory - log/ferret_server.pi (Errno::ENOENT) from /home/matt/IdeaProjects/autoissimo/vendor/plugins/acts_as_ferret/lib/unix_daemon.rb:53:in`open’  
from  
/home/matt/IdeaProjects/autoissimo/vendor/plugins/acts\_as\_ferret/lib/unix\_daemon.rb:53:in  
`write_pid_file' from /home/matt/IdeaProjects/autoissimo/vendor/plugins/acts_as_ferret/lib/unix_daemon.rb:12:in`platform\_daemon’  
from  
/home/matt/IdeaProjects/autoissimo/vendor/plugins/acts\_as\_ferret/lib/unix\_daemon.rb:41:in  
`fork' from /home/matt/IdeaProjects/autoissimo/vendor/plugins/acts_as_ferret/lib/unix_daemon.rb:41:in`safefork’  
from  
/home/matt/IdeaProjects/autoissimo/vendor/plugins/acts\_as\_ferret/lib/unix\_daemon.rb:11:in  
`platform_daemon' from /home/matt/IdeaProjects/autoissimo/vendor/plugins/acts_as_ferret/lib/ferret_server.rb:86:in`start’  
from ./…/vendor/plugins/acts\_as\_ferret/lib/server\_manager.rb:53:in  
`send' from ./../vendor/plugins/acts_as_ferret/lib/server_manager.rb:53 from ./ferret_server:4:in`require’  
from ./ferret\_server:4

Having looked into this a little I can see that when a config value for  
the pid file is defined in the ferret\_server.yml file the unix\_daemon.rb  
gets passed the file path without the rails root appended. When no  
value is specified within the ferret\_server.yml file the default values  
defined in ferret\_server.rb are used and the unix\_daemon.rb file gets  
passed the full path and the server starts.

Any help greatly appreciated 🙂

Apologies but there was a copy/paste error in the below stack trace:

No such file or directory - log/ferret\_server.pi

should be:

No such file or directory - log/ferret\_server.pid

I still have the error 🙂
