[jira] Updated: (AXISCPP-345) Server thread locks when fails to load the service shared library
Posted by "Unai Uribarri (JIRA)" <ax...@ws.apache.org>.
[ http://nagoya.apache.org/jira/browse/AXISCPP-345?page=history ]
Unai Uribarri updated AXISCPP-345:
----------------------------------
Attachment: SharedObjectLocking.diff
Instead of just solve this particular locking bug, I've reworked the SharedObject framework to use the Scoped Locking pattern.
To lock an object, just creates a <Lock> object passing a pointer to the object to lock. The lock is released automatically at lock destruction or manually calling the unlock method.
This way, the code is more simple and the locks are always unlocked when a exception is raised (don't forget that any allocation, such as the push_back method of the containers, can raise an exception).
What do you think of this change?
