Rake Fails with "Expired Virtual Timer"

Question

The following is my environment:

• OS X 10.5
• Xcode 3.1.4
• rvm 0.1.38
• ruby 1.8.9-p399 (via rvm)
• rails 2.3.8

I started getting this error when rake tries to run my tests:

bash$ rake Virtual timer expired bash$ # End of output! 

And with tracing enabled:

 bash$ rake --trace ** Invoke default (first_time) ** Invoke test (first_time) ** Execute test ** Invoke test:units (first_time) ** Invoke db:test:prepare (first_time) ** Invoke db:abort_if_pending_migrations (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:abort_if_pending_migrations ** Execute db:test:prepare ** Invoke db:test:load (first_time) ** Invoke db:test:purge (first_time) ** Invoke environment ** Execute db:test:purge ** Execute db:test:load ** Invoke db:schema:load (first_time) ** Invoke environment ** Execute db:schema:load Virtual timer expired bash$ 

Answer 1

It seems that the problem is in ruby, rev23993 causes the virtual timer to expire when using forking , which in turn causes an error inside mysql .

A practical solution to the problem is to downgrade mysql from 2.8.1 to version 2.7:

 #environment.rb config.gem 'mysql', :version => '2.7'
