;;======================================================================
;; Extracting the data to display for runs
;;
;; This needs to be re-entrant such that it does one column per call
;; on the zeroeth call update runs data
;; on each subsequent call update one run (configurable - could do two, three ... or update until tdelta exceeded
;; on last run reset to zeroeth
;;
;;   1. select with run filters; area, target, runname, runstate, runstatus, starttime, duration
;;       - put this information into two data structures:
;;         a. hash of area/target/runname => runstruct #< ordernun, id, area, target, runname, state,
;;                                                        status, starttime, duration, non-deleted testcount>
;;            ordernum reflects order as received from sql query
;;         b. sparsevec of id => runstruct
;;   2. for each run in runshash ordered by ordernum do:
;;         retrieve data since last update for that run
;;         if there is a deleted test - retrieve full data
;;         if there are non-deleted tests register this run in the columns sparsevec
;;         if this is the zeroeth column regenerate the rows sparsevec
;;         if this column is in the visible zone update visible cells
;;
;; Other factors:
;;   1. left index handling:
;;       - add test/itempaths to left index as discovered, re-order and
;;         update row -> test/itempath mapping on each read run

;;         b. sparsevec of id => runstruct
;;   2. for each run in runshash ordered by ordernum do:
;;         retrieve data since last update for that run
;;         if there is a deleted test - retrieve full data
;;         if there are non-deleted tests register this run in the columns sparsevec
;;         if this is the zeroeth column regenerate the rows sparsevec
;;         if this column is in the visible zone update visible cells
