[Raphaël Badin <raphael.badin@xxxxxxxxxxxxx>]

Raphaël Badin has proposed merging lp:~rvb/launchpad/builders-timeout-bug-887078-use-getSpecificJobs into lp:launchpad with lp:~rvb/launchpad/builders-timeout-bug-887078 as a prerequisite.

Requested reviews:
  Launchpad code reviewers (launchpad-reviewers)
Related bugs:
  Bug #887078 in Launchpad itself: "Builder:+history timeout"
  https://bugs.launchpad.net/launchpad/+bug/887078

For more details, see:
https://code.launchpad.net/~rvb/launchpad/builders-timeout-bug-887078-use-getSpecificJobs/+merge/81736

This branches simply uses the newly created method getSpecificJobs when creating the builds list for page builder:+history.  The number of queries issued by BuildRecordsView.setupBuildList now only depends on the number of build types (and not on the number of builds).

= Tests =

./bin/test -vvc test_builder_views test_build_history_queries_count

= Q/A =

None

Your team Launchpad code reviewers is requested to review the proposed merge of lp:~rvb/launchpad/builders-timeout-bug-887078-use-getSpecificJobs into lp:launchpad.
