- Booking::store runs item-level and biblio-level clash
detection unconditionally on every call
- During checkout, C4::Circulation sets the booking status to
'completed' and calls ->store(), which triggers clash checks
- Combined with false positives from Biblio::check_booking
(e.g. checkouts on non-bookable sibling items inflating the
unavailable count), this throws
Koha::Exceptions::Booking::Clash resulting in a 500 error
- Running clash detection on a terminal transition is
unnecessary regardless; skip it for cancelled/completed
- Add _is_final_status_transition() helper that inspects the
dirty columns to detect completed/cancelled transitions
- Guard both clash detection blocks with the new helper
To test:
1. Have a biblio with two items: one bookable, one not
(bookable = 0).
2. Create a booking on the bookable item.
3. Check out the non-bookable item to a patron.
4. Check out the bookable item to the booking patron (this
triggers the completed transition via C4::Circulation).
5. Without the patch: 500 error from
Koha::Exceptions::Booking::Clash.
6. Apply the patch.
7. Repeat steps 2-4.
8. Verify the checkout succeeds and the booking transitions
to completed.
9. Run: prove t/db_dependent/Koha/Booking.t
and confirm the new subtest "store() skips clash
detection on terminal status transition" passes.
