michael@0 11 /*
michael@0 12 This is strictly implementation specific test for dom storage code from bug 600307.
michael@0 13 It exercises code for asynchronous data flushing with regard to cache life time and its preload.
michael@0 14
michael@0 15 "flush + reload" means to tell the database to store all pending data then wipe the cached content and reload it from the db
michael@0 16
michael@0 17 "reload" only means to simulate situation when there is a pending flush for an origin but a new cache is about to preload
michael@0 18 which is a corner case happening rarely ; this helps check the next preload operation will load correct data from the database anyway
michael@0 19
michael@0 20 Case 1: set | flush + reload | remove | set | remove | flush + reload | get ?= null
michael@0 21 checks coalescing optimization for single key changes does work correctly for repeated removals of a key
michael@0 22
michael@0 23 Case 2: set | set | clear | flush + reload | count ?= 0
michael@0 24 checks whether clear operation superseeds setting keys, the database must be empty for the origin
michael@0 25
michael@0 26 Case 3: set | set | clear | reload | count ?= 0
michael@0 27 check the corner case when a data clear flush is pending but a new cache is about to preload
