i've inherited a site that in production is generating dozens of "no block given" exceptions every 5 minutes.
the top of the stack trace is:
vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:42:in `add'
vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:33:in `get'
vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:22:in `call'
vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:22:in `fetch'
vendor/gems/nkallen-cache-money-0.2.5/lib/cash/accessor.rb:31:in `get'
so it appears that the problem is in the cache money plugin.
has anyone experienced something similar?
i've cut and pasted the relevant code below -- anyone more familiar with blocks able to discern any obvious problems?
11 def fetch(keys, options = {}, &block)
12 case keys
13 when Array
14 keys = keys.collect { |key| cache_key(key) }
15 hits = repository.get_multi(keys)
16 if (missed_keys = keys - hits.keys).any?
17 missed_values = block.call(missed_keys)
18 hits.merge!(missed_keys.zip(Array(missed_values)).to_hash)
19 end
20 hits
21 else
22 repository.get(cache_key(keys), options[:raw]) || (block ? block.call : nil)
23 end
24 end
25
26 def get(keys, options = {}, &block)
27 case keys
28 when Array
29 fetch(keys, options, &block)
30 else
31 fetch(keys, options) do
32 if block_given?
33 add(keys, result = yield(keys), options)
34 result
35 end
36 end
37 end
38 end
39
40 def add(key, value, options = {})
41 if repository.add(cache_key(key), value, options[:ttl] || 0, options[:raw]) == "NOT_STORED\r\n"
42 yield
43 end
44 end
