Closes #29968

Summary of Changes

  • Extends bookingIdempotencyKeyExtension in packages/prisma/extensions/booking-idempotency-key.ts to compute and assign idempotencyKey during update operations when a booking's status transitions to BookingStatus.ACCEPTED.
  • Prevents double-booking race conditions when PENDING bookings (which initially have idempotencyKey = null) are accepted via the confirmation handler.
  • Preserves null clearing when bookings are CANCELLED or REJECTED.

Verification

  • Verified that generateIdempotencyKey creates a deterministic UUIDv5 URL key based on startTime, endTime, userId, and reassignedById.
  • Safe handling across create, update, and updateMany Prisma operations.

📝 Walkthrough

Walkthrough

Booking creation now uses reassignedById when generating idempotency keys. Booking updates now generate keys when an existing booking becomes ACCEPTED and both booking times are provided. The update logic resolves the user ID from either userId or a connected user. Cancellation and rejection continue to clear idempotency keys, including in bulk updates.

Merge Risk: 🟠 High · up to 6165e

Status-only acceptance of pending bookings can leave them without an idempotency key, weakening duplicate-booking protection and creating a concrete correctness risk. This should be fixed before merging.

Generate idempotency keys from persisted booking fields.

When a booking is promoted to BookingStatus.ACCEPTED with a status-only update, this branch leaves the existing idempotencyKey unchanged. For pending bookings, that value is null. Resolve startTime, endTime, userId, and reassignedById from args.where, merge them with changed fields, and generate the key. This also prevents keys with an undefined userId.
