** A CellArray object contains a cache of pointers and sizes for a
** consecutive sequence of cells that might be held on multiple pages.
**
** The cells in this array are the divider cell or cells from the pParent
** page plus up to three child pages.  There are a total of nCell cells.
**
** pRef is a pointer to one of the pages that contributes cells.  This is
** used to access information such as MemPage.intKey and MemPage.pBt->pageSize
** which should be common to all pages that contribute cells to this array.
**
** apCell[] and szCell[] hold, respectively, pointers to the start of each
** cell and the size of each cell.  Some of the apCell[] pointers might refer
** to overflow cells.  In other words, some apCel[] pointers might not point
** to content area of the pages.
**
** A szCell[] of zero means the size of that cell has not yet been computed.
**
** The cells come from as many as four different pages:
**
**             -----------
**             | Parent  |
**             -----------
**            /     |     \
**           /      |      \
**  ---------   ---------   ---------
**  |Child-1|   |Child-2|   |Child-3|
**  ---------   ---------   ---------
**
** The order of cells is in the array is for an index btree is:
**
**       1.  All cells from Child-1 in order
**       2.  The first divider cell from Parent
**       3.  All cells from Child-2 in order
**       4.  The second divider cell from Parent
**       5.  All cells from Child-3 in order
**
** For a table-btree (with rowids) the items 2 and 4 are empty because
** content exists only in leaves and there are no divider cells.
**
** For an index btree, the apEnd[] array holds pointer to the end of page
** for Child-1, the Parent, Child-2, the Parent (again), and Child-3,
** respectively. The ixNx[] array holds the number of cells contained in
** each of these 5 stages, and all stages to the left.  Hence:
**
**    ixNx[0] = Number of cells in Child-1.
**    ixNx[1] = Number of cells in Child-1 plus 1 for first divider.
**    ixNx[2] = Number of cells in Child-1 and Child-2 + 1 for 1st divider.
**    ixNx[3] = Number of cells in Child-1 and Child-2 + both divider cells
**    ixNx[4] = Total number of cells.
**
** For a table-btree, the concept is similar, except only apEnd[0]..apEnd[2]
** are used and they point to the leaf pages only, and the ixNx value are:
**
**    ixNx[0] = Number of cells in Child-1.
**    ixNx[1] = Number of cells in Child-1 and Child-2 + 1 for 1st divider.
**    ixNx[2] = Number of cells in Child-1 and Child-2 + both divider cells

** Generate code for scalar subqueries used as a subquery expression, EXISTS,

**
**     (SELECT a FROM b)          -- subquery
**     EXISTS (SELECT a FROM b)   -- EXISTS subquery
**     x IN (4,5,11)              -- IN operator with list on right-hand side
**     x IN (SELECT a FROM b)     -- IN operator with subquery on the right
**
** The pExpr parameter describes the expression that contains the IN
** operator or subquery.



**
** If parameter isRowid is non-zero, then expression pExpr is guaranteed

























** to be of the form "<rowid> IN (?, ?, ?)", where <rowid> is a reference


** to some integer key column of a table B-Tree. In this case, use an



























** intkey B-Tree to store the set of IN(...) values instead of the usual






** (slower) variable length keys B-Tree.

























**


























































** If rMayHaveNull is non-zero, that means that the operation is an IN







** (not a SELECT or EXISTS) and that the RHS might contains NULLs.









** All this routine does is initialize the register given by rMayHaveNull
























** to NULL.  Calling routines will take care of changing this register





** value to non-NULL if the RHS is NULL-free.



**





** For a SELECT or EXISTS operator, return the register that holds the
** result.  For a multi-column SELECT, the result is stored in a contiguous
** array of registers and the return value is the register of the left-most
** result column.  Return 0 for IN operators or if an error occurs.

**     x IN (SELECT a FROM b)     -- IN operator with subquery on the right
**
** The pExpr parameter is the IN operator.  The cursor number for the
** constructed ephermeral table is returned.  The first time the ephemeral
** table is computed, the cursor number is also stored in pExpr->iTable,
** however the cursor number returned might not be the same, as it might
** have been duplicated using OP_OpenDup.
**
** If parameter isRowid is non-zero, then LHS of the IN operator is guaranteed
** to be a non-null integer. In this case, the ephemeral table can be an
** table B-Tree that keyed by only integers.  The more general cases uses
** an index B-Tree which can have arbitrary keys, but is slower to both
** read and write.
**
** If the LHS expression ("x" in the examples) is a column value, or
** the SELECT statement returns a column value, then the affinity of that
** column is used to build the index keys. If both 'x' and the
** SELECT... statement are columns, then numeric affinity is used
** if either column has NUMERIC or INTEGER affinity. If neither
** 'x' nor the SELECT... statement are columns, then numeric affinity
** is used.

** The vacuum can be resumed by calling this function to open a new RBU
** handle specifying the same target and state databases.
**
** If the second argument passed to this function is NULL, then the
** name of the state database is "<database>-vacuum", where <database>
** is the name of the target database file. In this case, on UNIX, if the
** state database is not already present in the file-system, it is created
** with the same permissions as the target db is made.




**
** This function does not delete the state database after an RBU vacuum
** is completed, even if it created it. However, if the call to
** sqlite3rbu_close() returns any value other than SQLITE_OK, the contents
** of the state tables within the state database are zeroed. This way,
** the next call to sqlite3rbu_vacuum() opens a handle that starts a 
** new RBU vacuum operation.
