Currently, CallLinkStatus knows what to query but it does so behind an opaque API that assumes that it's querying the CallLinkInfo for a op_call/op_construct instruction. This would make it difficult to integrate with a different Status class that wants to use a CallLinkInfo that is embedded inside a stub, like GetByIdStatus or PutByIdStatus - those will only see that there is a CallLinkInfo for which to compute status while they are already holding the "wrong" lock for computing exit site data. We should refactor things so that: - You can ask CallLinkStatus to compute exit site data - essentially an opaque data token - without giving it the CallLinkInfo. - You can pass the exit site data and the CallLinkInfo and get a complete CallLinkStatus. - Do what you do now - i.e. we shouldn't change the existing API that just does all of this for you. 1010050 1 231648 fpizlo 2014-05-17 22:55:49
