[Adobe-source-devel] The possible overflow of priority_high_m in sheet

[cee1 <fy...@gm...>]

Hi all,

I notice each time touch/set a cell, priority_high_m is increased and
its value is assigned to
cell's priority_m field.

So theoretically, it's possible to overflow priority_high_m, right? E.g.

Considering in an automated UI test, (only) a text entry is frequently
updated, the priority_m of the backed cell is continuously increased,
and will finally overflow.

The priority_m is (only) used in flow(): to sort the cells, and
process the relations attached to a cell one by one, right?
In other words, only the sequence is cared, not the distance.


So what about maintaining a `priority list', if a cell is touched/set,
move to .begin() ?

Moreover, it may change type of the priority_m to a pointer of `link
node of the list', then if a cell is touched/set, it will be unlinked,
and reinserted to .begin() quickly.
