** 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.
+** ixNx[2] = Total number of cells.
+**
+** Sometimes when deleting, a child page can have zero cells. In those
+** cases, ixNx[] entries with higher indexes, and the corresponding apEnd[]
+** entries, shift down. The end result is that each ixNx[] entry should

+** code to populate the Window.regResult register for each window function
+** and invoke the sub-routine at instruction addrGosub once for each row.
+** sqlite3WhereEnd() is always called before returning.
+**
+** This function handles several different types of window frames, which
+** require slightly different processing. The following pseudo code is
+** used to implement window frames of the form:
+**
+** ROWS BETWEEN PRECEDING AND FOLLOWING
+**
+** Other window frame types use variants of the following:
+**
+** ... loop started by sqlite3WhereBegin() ...
+** if( new partition ){
+** Gosub flush
+** }
+** Insert new row into eph table.
+**
+** if( first row of partition ){

+** regStart = // PRECEDING expression
+** }else{
+** // First time this branch is taken, the eph table contains two
+** // rows. The first row in the partition, which all three cursors
+** // currently point to, and the following row.
+** AGGSTEP
+** if( (regEnd--)<=0 ){
+** RETURN_ROW
+** if( (regStart--)<=0 ){
+** AGGINVERSE
+** }
+** }
+** }
+** }
+** flush:
+** AGGSTEP
+** while( 1 ){
+** RETURN ROW
+** if( csrCurrent is EOF ) break;
+** if( (regStart--)<=0 ){
+** AggInverse(csrStart)
+** Next(csrStart)
+** }
+** }
+**
+** The pseudo-code above uses the following shorthand:
+**
+** AGGSTEP: invoke the aggregate xStep() function for each window function
+** with arguments read from the current row of cursor csrEnd, then
+** step cursor csrEnd forward one row (i.e. sqlite3BtreeNext()).
+**
+** RETURN_ROW: return a row to the caller based on the contents of the
+** current row of csrCurrent and the current state of all
+** aggregates. Then step cursor csrCurrent forward one row.
+**
+** AGGINVERSE: invoke the aggregate xInverse() function for each window
+** functions with arguments read from the current row of cursor
+** csrStart. Then step csrStart forward one row.
+**
+** There are two other ROWS window frames that are handled significantly
+** differently from the above - "BETWEEN PRECEDING AND PRECEDING"
+** and "BETWEEN FOLLOWING AND FOLLOWING". These are special
+** cases because they change the order in which the three cursors (csrStart,
+** csrCurrent and csrEnd) iterate through the ephemeral table. Cases that
+** use UNBOUNDED or CURRENT ROW are much simpler variations on one of these
+** three.
+**
+** ROWS BETWEEN PRECEDING AND PRECEDING
+**
+** ... loop started by sqlite3WhereBegin() ...
+** if( new partition ){

+** AGGINVERSE
+** if( eof ) break
+** }
+** }
+** while( !eof csrCurrent ){
+** RETURN_ROW
+** }
+**
+** For the most part, the patterns above are adapted to support UNBOUNDED by
+** assuming that it is equivalent to "infinity PRECEDING/FOLLOWING" and
+** CURRENT ROW by assuming that it is equivilent to "0 PRECEDING/FOLLOWING".
+** This is optimized of course - branches that will never be taken and
+** conditions that are always true are omitted from the VM code. The only
+** exceptional case is:
+**
+** ROWS BETWEEN FOLLOWING AND UNBOUNDED FOLLOWING
+**
+** ... loop started by sqlite3WhereBegin() ...
+** if( new partition ){
+** Gosub flush
+** }
+** Insert new row into eph table.

+** AGGINVERSE
+** if( eof ) break
+** }
+** RETURN_ROW
+** }
+** while( !eof csrCurrent ){
+** RETURN_ROW
+** }
+**
+** Also requiring special handling are the cases:
+**
+** ROWS BETWEEN PRECEDING AND PRECEDING
+** ROWS BETWEEN FOLLOWING AND FOLLOWING
+**
+** when (expr1 < expr2). This is detected at runtime, not by this function.
+** To handle this case, the pseudo-code programs depicted above are modified
+** slightly to be:
+**
+** ... loop started by sqlite3WhereBegin() ...
+** if( new partition ){
+** Gosub flush
+** }
+** Insert new row into eph table.
+** if( first row of partition ){
+** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
+** regEnd =
+** regStart =
+** if( regEnd < regStart ){
+** RETURN_ROW
+** delete eph table contents
+** continue
+** }
+** ...
+**
+** The new "continue" statement in the above jumps to the next iteration
+** of the outer loop - the one started by sqlite3WhereBegin().
+**
+** The various GROUPS cases are implemented using the same patterns as
+** ROWS. The VM code is modified slightly so that:
+**
+** 1. The else branch in the main loop is only taken if the row just
+** added to the ephemeral table is the start of a new group. In
+** other words, it becomes:
+**
+** ... loop started by sqlite3WhereBegin() ...
+** if( new partition ){
+** Gosub flush
+** }
+** Insert new row into eph table.
+** if( first row of partition ){
+** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
+** regEnd =
+** regStart =
+** }else if( new group ){
+** ...
+** }
+** }
+**
+** 2. Instead of processing a single row, each RETURN_ROW, AGGSTEP or
+** AGGINVERSE step processes the current row of the relevant cursor and
+** all subsequent rows belonging to the same group.
+**
+** RANGE window frames are a little different again. As for GROUPS, the
+** main loop runs once per group only. And RETURN_ROW, AGGSTEP and AGGINVERSE
+** deal in groups instead of rows. As for ROWS and GROUPS, there are three
+** basic cases:
+**
+** RANGE BETWEEN PRECEDING AND FOLLOWING
+**
+** ... loop started by sqlite3WhereBegin() ...
+** if( new partition ){
+** Gosub flush
+** }
+** Insert new row into eph table.
+** if( first row of partition ){
+** Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
+** regEnd =
+** regStart =
+** }else{
+** AGGSTEP
+** while( (csrCurrent.key + regEnd) < csrEnd.key ){
+** RETURN_ROW
+** while( csrStart.key + regStart) < csrCurrent.key ){
+** AGGINVERSE
+** }
+** }
+** }
+** }

+** RETURN ROW
+** if( csrCurrent is EOF ) break;
+** while( csrStart.key + regStart) < csrCurrent.key ){
+** AGGINVERSE
+** }
+** }
+** }
+**
+** In the above notation, "csr.key" means the current value of the ORDER BY
+** expression (there is only ever 1 for a RANGE that uses an FOLLOWING
+** or PRECEDING AND PRECEDING
+**

- /* There are three different functions that may be used to do the work

- ** window functions used (if any).
- **
- ** windowCodeRowExprStep() handles all "ROWS" window frames, except for:
- **
- ** ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
- **
- ** The exception is because windowCodeRowExprStep() implements all window
- ** frame types by caching the entire partition in a temp table, and
- ** "ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW" is easy enough to
- ** implement without such a cache.
- **
- ** windowCodeCacheStep() is used for:
- **
- ** RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING
- **
- ** It is also used for anything not handled by windowCodeRowExprStep()
- ** that invokes a built-in window function that requires the entire
- ** partition to be cached in a temp table before any rows are returned
- ** (e.g. nth_value() or percent_rank()).
- **
- ** Finally, assuming there is no built-in window function that requires
- ** the partition to be cached, windowCodeDefaultStep() is used for:
- **
- ** RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
- ** RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING
- ** RANGE BETWEEN CURRENT ROW AND CURRENT ROW
- ** ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
- **
- ** windowCodeDefaultStep() is the only one of the three functions that
- ** does not cache each partition in a temp table before beginning to
- ** return rows.
