Strange Fix for the Strangest Bug

June 2nd, 2010

I have no idea why this bug fix works, but it does. When I run tidy_ffi via a Unicorn, a Sinatra app, and Rack-XSLView manually, it works fine. If I run it via daemontools, it returns an empty string because for some reason LibTidy.tidyReleaseDate isn't return a date!

UPDATE: This wasn't the end of it. I submitted the fix to libc (Eugene), and he said the check was needed for Mac OS X which ships with an older version of libTidy. I dug deeper, and found that the date was getting returned, but it just wasn't getting processed correctly. After that, I did some external troubleshooting, and found that in irb1.9.1 I had to require 'date' to parse the date libTidy was returning. I switched out require 'rubygems' with require 'date', and the bug went away. Yay!
