[chef-dev] Re: checksum_cache.rb crash on cookbook upload

[Joseph Holsten < >]

Relevant line in the code  
https://github.com/opscode/chef/blob/0.10.6/chef/lib/chef/checksum_cache.rb#L174

That io.read(n) loop should return <= n bytes at the EOF, then return nil. 
Definitely shouldn't blow up. I'm betting it's a off-by-one line number, and 
that something strange is happening in Digest::MD5#update.

Does your cookbook happen to include binary files? Any other common factors 
when this happens?
