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.

Parameters: __mode Whether the buffer can read, or write, or both. ios_base::out is automatically included in mode. Initializes sb using mode|out, and passes &sb to the base class initializer.

Parameters: __rhs The source values for the copies. Returns: Reference to this object. All fields of __rhs are copied into this object except that rdbuf() and rdstate() remain unchanged. All values in the pword and iword arrays are copied. Before copying, each callback is invoked with erase_event. After copying, each (new) callback is invoked with copyfmt_event.

Parameters: __except The new exceptions mask. By default, error flags are set silently. You can set an exceptions mask for each stream; if a bit in the mask becomes set in the error flags, then an exception of type std::ios_base::failure is thrown. If the error flag is already set when the exceptions mask is added, the exception is immediately thrown.

Parameters: __sb A pointer to a streambuf This function behaves like one of the basic arithmetic extractors, in that it also constructs a sentry object and has the same error handling behavior. If __sb is NULL, the stream will set failbit in its error state. Characters are extracted from __sb and inserted into *this until one of the following occurs: o the input stream reaches end-of-file, o insertion into the output sequence fails (in this case, the character that would have been inserted is not extracted), or o an exception occurs while getting a character from __sb, which sets failbit in the error state If the function inserts no characters, failbit is set.

Parameters: __ix Index into the array. Returns: A reference to a void* associated with the index. The pword function provides access to an array of pointers that can be used for any purpose. The array grows as required to hold the supplied index. All pointers in the array are initialized to 0. The implementation reserves several indices. You should use xalloc to obtain an index that is safe to use. Also note that since the array can grow dynamically, it is not safe to hold onto the reference.

Parameters: __sb The new stream buffer. Returns: The previous stream buffer. Associates a new buffer with the current stream, and clears the error state. Due to historical accidents which the LWG refuses to correct, the I/O library suffers from a design error: this function is hidden in derived classes by overrides of the zero-argument rdbuf(), which is non-virtual for hysterical raisins. As a result, you must use explicit qualifications to access this function via any derived class.

Returns: An integer different from all previous calls. This function returns a unique integer every time it is called.

The implementation maintains a static variable that is incremented and returned on each invocation. xalloc is guaranteed to return an index that is safe to use in the iword and pword arrays.
