Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

pthread_attr_getstack, pthread_attr_setstack - get or set stack attributes
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_attr_getstack(const pthread_attr_t *restrict attr, void **restrict stackaddr, size_t *restrict stacksize); int pthread_attr_setstack(pthread_attr_t * attr, void *stackaddr, size_t stacksize);
The pthread_attr_getstack() and pthread_attr_setstack() functions, respectively, get and set the thread creation stack attributes stackaddr and stacksize in the attr object. The stack attributes specify the area of storage to be used for the created thread's stack. The base (lowest addressable byte) of the stor- age is stackaddr, and the size of the storage is stacksize bytes. The stacksize argument must be at least {PTHREAD_STACK_MIN}. The stack- addr argument must be aligned appropriately to be used as a stack; for example, pthread_attr_setstack() might fail with EINVAL if (stack- addr & 0x7) is not 0. All pages within the stack described by stackaddr and stacksize are both readable and writable by the thread.
Upon successful completion, these functions return a 0; otherwise, an error number is returned to indicate the error. The pthread_attr_getstack() function stores the stack attribute values in stackaddr and stacksize if successful.
The pthread_attr_setstack() function will fail if: EINVAL The value of stacksize is less than {PTHREAD_STACK_MIN}. The pthread_attr_setstack() function may fail if: EACCES The stack page(s) described by stackaddr and stacksize are not both readable and writable by the thread. EINVAL The value of stackaddr does not have proper alignment to be used as a stack, or (stackaddr + stacksize) lacks proper alignment.
These functions are appropriate for use by applications in an environment where the stack for a thread must be placed in some particular region of memory.
