Detailed Description

struct of data for 1 nested SIL callback within 1 undo.

each distinct SIL callback within a subtree will have a separate nested_silcall record

this is done for each call to handle_user_callback

This record is maintained throughout the transaction starting in validate phase when the input val_value_t tree is scanned. Each queue of nested_silcall is sorted by SIL priority first

Field Documentation

curval_clone

val_value_t* curval_clone

In case of delete-children-first mode newval and curval may get cleaned and deleted before the actual children callback is invoked, Which may cause newval/curval backptrs become tainted and not usable anymore.

Need to keep the actual curval in case we need to process reverse deletion from bottom to top.

This is malloced value; Must be freed
