rietta

My first attempts at running a new Rails application on JRuby is completely failing.  Through the process of elimination, I have traced the source of the problem down to the asset pipeline in Rails 3.2.  Though I do not know how to fix this:

   stat.st_gid unsupported or native support failed to load
   org/jruby/RubyFileStat.java:432:in `gid'

This is on October 20, 2012.  Using jruby 1.6.7 and Rails 3.2.8 out of the box with the gems as published on this date.

Here are the steps to reproduce - again, no custom code on my part.

Using Mac OS X Mountain Lion, I installed the following:

update pg_database set datallowconn = TRUE where datname = 'template0';
\c template0
update pg_database set datistemplate = FALSE where datname = 'template1';
drop database template1;
create database template1 with template = template0 encoding = 'UTF8';
update pg_database set datistemplate = TRUE where datname = 'template1';
\c template1
update pg_database set datallowconn = FALSE where datname = 'template0';

#!/usr/bin/nice /bin/bash

#
# Your script goes here....
#

# Now when this script is run from the command line as ./run_as_nice.sh, it will execute with lower 
# priority to avoid causing the load average to spike as much.

After upgrading from Ruby 1.9.2 to 1.9.3 on a test server, the pg would not install.

   mv ~/.rvm/usr/lib ~/.rvm/usr/lib_rvm 
   bundle config build.pg --with-pg-config=/usr/bin/pg_config.libpq-dev
   gem install pg


The mv line was the breakthrough, see:
