Hello in glusterd_op_sm(), we lock and unlock the gd_op_sm_lock mutex. Unfortunately, locking and unlocking can happen in different threads (task swap will occur in handelr call).
This case is explictely covered by POSIX: the behavior is undefined. http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_mutex_lock.html When unlocking from a thread that is not owner, Linux seems to be fine (though you never know with unspecified operation), while NetBSD returns EPERM, causing a spurious error in tests/basic/pump.t . It can be observed in a few failed tests here: http://build.gluster.org/job/rackspace-netbsd7-regression-triggered/ Fixing it seems far from being obvious. I guess it needs to use syncop, but the change would be intrusive. Do we have another option? Is it possible to switch a task to a given thread? -- Emmanuel Dreyfus [email protected] _______________________________________________ Gluster-devel mailing list [email protected] http://supercolony.gluster.org/mailman/listinfo/gluster-devel
