Comments on: Autotest CPU Fix

After editing my ~/.autotest file as described, got this message when starting autotest:

hook run has been deprecated, use initialize

After making the change suggested by Scott (thanks!), the message disappeared.

But it still ran slow, so I added more directories. Responds about 10 times faster now!

Here’s what I did (some are probably already excluded by default):

Autotest.add_hook :initialize do |autotest|
autotest.add_exception(/^\.\/vendor/)
autotest.add_exception(/^\.\/artwork/)
autotest.add_exception(/^\.\/public/)
autotest.add_exception(/^\.\/db/)
autotest.add_exception(/^\.\/lib/)
autotest.add_exception(/^\.\/tmp/)
autotest.add_exception(/\.svn/)
end

If you’re getting the “exceptions already compiled” error, you could try changing the hook to “Autotest.add_hook :initialize”. I didn’t need to do that, but both work.

Needed to update rspec too - works like a charm.

Thanks!

I have also noticed absurd CPU usage spikes with autotest. So I was happy to see this post. I upgraded ZenTest to 3.8.0 and put the updated code in my ~/.autotest and now get the following bustage:

loading autotest/rails_rspec
/usr/local/lib/ruby/gems/1.8/gems/ZenTest-3.8.0/lib/autotest.rb:515:in `add_exception’: exceptions already compiled (RuntimeError)

Any ideas?

This was really helpful, thank you.

Thanks! This helped me stop acts_as_solr from making autotest run in a continuous loop when the plugin log files were updated!

Thanks for posting this. I noticed the same thing but vendor wasn’t my issue. I ran ‘find’ looking for a big chunk of files and found them in .git This is a project where I’m using git-svn. After adding .git to the exception CPU usage is down below 5%.

I should have communicated more and synchronized with Dave about the changes I made to @exceptions. sorry. We’ll both release something soon to get them back in sync and happier with each other.
