             Bug #: 7016
           Summary: CanBookBeReserved uses GetItemsInfo unnecessarily
    Classification: Unclassified
 Change sponsored?: ---
           Product: Koha
           Version: rel_3_6
          Platform: All

            Status: NEW
          Severity: normal
          Priority: P5
         Component: Architecture, internals, and plumbing

C4::Reserves::CanBookBeReserved uses GetItemsInfo($biblionumber) to get the
itemnumbers for all the items attached to the biblio in question.  However,
GetItemsInfo is a very heavy-weight subroutine, pulling in data from all over
the database.  This data includes a run of C4::Reserves::CheckReserves(), as
well as pulling in the last three borrowers from old_issues.

Using get_itemnumbers_of(($biblionumber)) would greatly reduce the cost of
CanBookBeReserved.
