[jira] Updated: (QPID-1108) QPID broker asserts in qpid::sys::RWlock::RWlock()

["Manuel Teira (JIRA)" <qp...@incubator.apache.org>]

Manuel Teira updated QPID-1108:
-------------------------------

    Attachment: mutex-fix.patch

This patch deletes the initialization machinery for RWlock, since we don't need it to use just default attributes in pthread_rwlock_init. Furthermore, reusing the same pthread_once_t attribute will lead to unitialized values in Mutex or RWlock, depending on the first one to be called.

> Creation of a RWlock asserts in the call:
> QPID_POSIX_ASSERT_THROW_IF(pthread_rwlock_init(&rwlock, recursiveRWlockattr));
> As discussed in the dev maillist, the problem is reusing the pthread_once_t variable to initialize both the RWlock and Mutex initialization attrs. Furthermore, this machinery is not even needed for RWlock, as default attributes would suffice.
