What would be a good way to prevent it from running in all cases?

only_if? not_if?  Some provider specific parameter?

package "must-be-version-locked" do

 version "foo"

end

package "totally-sucks-devel"

on_failure "run apt-get update" do
  match /^package/
  no_match /version/

  notifies :run, "execute[apt-get-update]"
end

I like the concept, should be careful to set it up in a way that doesn't cause unexpected side effects, especially when including things from dependencies. Would it be possible to scope it to the calling cookbook?

Oooh... that looks yummy. I like the idea of being able to stop a service if a later resource (say something being deployed) fails.

Why don't we make this a resource?

package "totally-sucks-devel"

on_failure "run apt-get update" do

end

Where match is a regular _expression_ that looks for names of resources.

What about extending the current handler approach? Add the ability to
catch
a failed resource (by name) and retry it, just like you can with a
begin/rescue.

I like the concept of having an exception handler be tied to a
resource or provider, or at least be able to determine what resource
or provider caused the exception, do some bits and retry.
