Subject
| [sca-c-cpp] NEW ISSUE: Clarify Request
Scope lifetime |
|
TARGET: SCA C++ and C Specification sections titled "Request Scope"
(2.3.2 of WD 04)
DESCRIPTION:
The section currently contains the following sentence:
"The lifecycle of request scope extends from the point a request on
a remotable interface enters the SCA runtime and a thread processes that
request until the thread completes synchronously processing the request."
From this description, it is not clear whether the request scope lasts
through a remotable call to another component that happens to be local.
In one possible interpretation it would depend on the binding. A call through
a web service binding would be seen as changing threads, and therefore
would be a new request scope. The same call through an SCA binding might
be assumed to remain within the thread and therefore be within the same
scope.
It is probably a bad idea for the scope to depend on the binding that is
used, and it may even be a bad idea for the scope to depend on whether
a call through a remotable interface _happens_ to be local.
PROPOSALS:
None yet - wait on Assembly TC action.
