55 C4::Reserves - Koha functions for dealing with reservation.
63 This modules provides somes functions to deal with reservations.
65 Reserves are stored in reserves table.
66 The following columns contains important values :
67 - priority >0 : then the reserve is at 1st stage, and not yet affected to any item.
68 =0 : then the reserve is being dealed
69 - found : NULL : means the patron requested the 1st available, and we haven't chosen the item
70 T(ransit) : the reserve is linked to an item but is in transit to the pickup branch
71 W(aiting) : the reserve is linked to an item, is at the pickup branch, and is waiting on the hold shelf
72 F(inished) : the reserve has been completed, and is done
73 P(rocessing) : reserved item has been returned using self-check machine and reserve needs to be confirmed
74 by librarian before notice is send and status changed to waiting.
75 Applicable only if HoldsNeedProcessingSIP system preference is set.
76 - itemnumber : empty : the reserve is still unaffected to an item
77 filled: the reserve is attached to an item
78 The complete workflow is :
79 ==== 1st use case ====
80 patron request a document, 1st available : P >0, F=NULL, I=NULL
81 a library having it run "transfertodo", and clic on the list
82 if there is no transfer to do, the reserve waiting
83 patron can pick it up P =0, F=W, I=filled
84 if there is a transfer to do, write in branchtransfer P =0, F=T, I=filled
85 The pickup library receive the book, it check in P =0, F=W, I=filled
86 The patron borrow the book P =0, F=F, I=filled
88 ==== 2nd use case ====
89 patron requests a document, a given item,
90 If pickup is holding branch P =0, F=W, I=filled
91 If transfer needed, write in branchtransfer P =0, F=T, I=filled
92 The pickup library receive the book, it checks it in P =0, F=W, I=filled
93 The patron borrow the book P =0, F=F, I=filled

1065 If C<$rank> is 'del', the hold request is cancelled.

1591 This routine adjusts the priority of a hold request and holds
1594 In the first form, where a reserve_id is passed, the priority of the
1595 hold is set to supplied rank, and other holds for that bib are adjusted
1596 accordingly. If the rank is "del", the hold is cancelled. If no rank
1597 is supplied, all of the holds on that bib have their priority adjusted
1598 as if the second form had been used.
1600 In the second form, where a biblionumber is passed, the holds on that
1601 bib (that are not captured) are sorted in order of increasing priority,
1602 then have reserves.priority set so that the first non-captured hold
1603 has its priority set to 1, the second non-captured hold has its priority
1604 set to 2, and so forth.
1606 In both cases, holds that have the lowestPriority flag on are have their
1607 priority adjusted to ensure that they remain at the end of the line.

2231 the current system time and that are neither on the hold shelf
2234 The reserve date parameter is optional; if it is supplied, the
2235 priority is based on the set of holds whose start date falls before
2236 the parameter value.

2239 _ShiftPriorityByDateAndPriority. Note that this is currently done in
