Locking cleanup for management objects
--------------------------------------
Key: QPID-1088
URL: https://issues.apache.org/jira/browse/QPID-1088
Project: Qpid
Issue Type: Improvement
Components: C++ Broker
Affects Versions: M3
Reporter: Ted Ross
Assignee: Ted Ross
Priority: Minor
Fix For: M3
A recent change to the management code generator caused excessive locking
during the increment and decrement of counter statistics in management objects.
This update does the following:
1) Change RW locks in management objects to Mutexes
2) Remove locking for increment and decrement operations on counters
3) Provide user access to the management object mutex
4) Add higher-level locking in the broker::Queue class to protect all counter
operations as a block.
There should now be only one lock taken out for management during the
production or consumption of a message.
