Hi all, This set is a subset of a larger series for parent pointers (v9). Delayed attributes allow attribute operations (set and remove) to be logged and committed in the same way that other delayed operations do. This will help break up more complex operations when we later introduce parent pointers which can be used in a number of optimizations. Since delayed attributes can be implemented as a stand alone feature, I've decided to subdivide the set to help make it more manageable. Changes since parent pointers v9: This is mostly to update the set onto more recent code. Some time during v8, concerns were raised about the transaction becoming too large, and we discussed breaking up the set operation by periodically returning EAGAIN to cycle out the transaction during the finish routine. This is done in patches 7 and 8, but I dont recall them getting feedback as people were quite busy at the time. Questions, comments, feedback appreciated! Thanks all!
