The _config/route rules explicitly mentioned framework by module name,
so if you installed framework in the older sapphire directory youd
always end up with cyclic config requirement errors
It is possible to specify before and after rules on config fragments
that conflict - A before B and B before A isnt possible to solve.
This used to just throw an error with no way to debug. Now if you
specify debug as a GET parameter and the site is not in live mode
youll get a basic dump of the remaining DAG graph
When specifying a specific before rule and a wildcard after rule (or
vice versa), the config system was filtering out any fragment
from the list of fragments that matched the wildcard if it matched
_any_ componenet of the specific rule, not all of them.
Fixed, and added handling of two semi wild-card rules, where a
rule with less wildcards wins over a rule with more.
See http://open.silverstripe.org/ticket/7765 for more
You should be able to specify multiple before and after rules in
a config fragment. This was intended to be a comma seperated string
but that wasnt being split properly
Now if you provide a comma seperated string it is split properly,
but you can also provide an array, which is actually cleaner
- Do not skip the cache if there are currently no environmental specific spec, just use the an empty variantKeySpec.
- When doing a regeneration of the config, clear the previous values from the array before regeneration.
