Dmitry Lenev dcaa144852 Fix for bug #51105 "MDL deadlock in rqg_mdl_stability test ... on Windows". On platforms where read-write lock implementation does not prefer readers by default (Windows, Solaris) server might have deadlocked while detecting MDL deadlock. MDL deadlock detector relies on the fact that read-write locks which are used in its implementation prefer readers (see new comment for MDL_lock::m_rwlock for details). So far MDL code assumed that default implementation of read/write locks for the system has this property. Indeed, this turned out ot be wrong, for example, for Windows or Solaris. Thus MDL deadlock detector might have deadlocked on these systems. This fix simply adds portable implementation of read/write lock which prefer readers and changes MDL code to use this new type of synchronization primitive. No test case is added as existing rqg_mdl_stability test can serve as one.		2010-02-28 07:35:09 +03:00
