[OSSTEST PATCH 00/11] Improve performance of sg-report-host-history

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

This is reasonably straightforward.

In my tests it reduces the time for an incremental run, with a hot
cache, from several hundred seconds to a handful of seconds.

This series really wants to go after the flight report improvements,
although the schema updates could be combined.

Ian Jackson (11):
  schema: Add index for quick lookup by host
  sg-report-host-history: Find flight limit by flight start date
  sg-report-host-history: Drop per-job debug etc.
  Executive: Export opendb_tests
  sg-report-host-history: Add a debug print after sorting jobs
  sg-report-host-history: Do the main query per host
  sg-report-host-history: Rerganisation: Make mainquery per-host
  sg-report-host-history: Rerganisation: Read old logs later
  sg-report-host-history: Rerganisation: Change loops
  sg-report-host-history: Drop a redundznt AND clause
  sg-report-host-history: Fork
