Help with yum_package flush_cache optiop


#1

https://docs.chef.io/resource_package.html

Above documentation for flush_cache gives a syntax error. What is the correct syntax?

Can you show us what you have and the error you’re getting?

The format should be something like:

Works in all Rubies

yum_package ‘some-package’ do#…
flush_cache({ :before => false, :after => false })#…end

Also works in Ruby >= 1.9

yum_package ‘some-package’ do#…
flush_cache({ before: false, after: false })#…end

Ordinarily, the parentheses on resource attributes aren’t required, but
without them, in this case, the Ruby syntax parser has no way of
differentiating between a hash argument and a block argument. That is, this
does not work:

yum_package ‘some-package’ do#…
flush_cache { :before => false, :after => false }#…end

syntax error, unexpected =>, expecting ‘}’# flush_cache { :before

=> false, :after => false }# ^

If I had to guess, perhaps this is the error you’re getting?

The correct syntax, after playing with it is

package ‘some_rpm’ do
flush_cache [ :before, :after ]
end

Yes, that apparently works too. The code in the resource appears to have some
logic
https://github.com/chef/chef/blob/master/lib/chef/resource/yum_package.rb#L45-L46
in it to handle being given an array instead of the hash. Although that
feature is missing from the docs.

Can you file an issue against chef-docs?
