Rails DB rake tasks run but never exit

Question

When I run any of the rake db tasks that Rails provides, they run successfully but never exit. I have to CTRL+C to quit the task. I've tested running it for over 8 hours and the problem persists.

Here's the output if I run rake db:migrate --trace:

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:migrate
** Invoke db:schema:dump (first_time)
** Invoke db:load_config 
** Execute db:schema:dump
_

Like I said, everything runs as expected, but it hangs after db:schema:dump.

I'm using the following:

• Mac OS X 10.7.1 (Lion)
• Ruby 1.9.2p290
• Rails 3.1.0
• MySQL 5.5.14
• mysql2 gem 0.3.7

I'll also note that this is a base Rails app with no gems/code added. I can replicate with rails new testapp -d mysql then rake db:create or bundle exec rake db:create.

Has anyone run into this problem or know what I can do to further troubleshoot?

Answer 1

I fixed the problem.

First, I tried uninstalling the version of MySQL that was installed using the official binary then reinstalling using Homebrew. That did nothing.

I then ran brew update, restarted MySQL, and tried again. Eureka! It worked.

The culprit seems to have been a bug in an older version of one of the following:

libiconv
glib
gtk+

Those were the only formulas that were updated.

Answer 2

same thing happen with me also but don't worry, i tried out bundle update after this i never face this issue.
