Ensure request counter is atomically incremented
------------------------------------------------
Key: SLING-2370
URL: https://issues.apache.org/jira/browse/SLING-2370
Project: Sling
Issue Type: Improvement
Components: Engine
Affects Versions: Engine 2.2.4
Reporter: Felix Meschberger
Assignee: Felix Meschberger
Fix For: Engine 2.2.6
The SlingHttpServletResponseImpl contains the request counter, which is a
static value incremented on each request. In case of heave concurrency, this
counter may yield the same value for two different requests.
Using an AtomicLong (instead of int) we can ensure atomicity of update and
retrieval and at the same time increase the number of unique request ids (int
was probably wrong anyway in this respect and it should have been long from the
start).
