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

1029 If C<$rank> is 'del', the hold request is cancelled.

1032 the request is set to that value. Since priority != 0 means

1566 In the first form, where a reserve_id is passed, the priority of the

1568 accordingly. If the rank is "del", the hold is cancelled. If no rank
1569 is supplied, all of the holds on that bib have their priority adjusted
1570 as if the second form had been used.
1572 In the second form, where a biblionumber is passed, the holds on that
1573 bib (that are not captured) are sorted in order of increasing priority,
1574 then have reserves.priority set so that the first non-captured hold
1575 has its priority set to 1, the second non-captured hold has its priority
1576 set to 2, and so forth.
1578 In both cases, holds that have the lowestPriority flag on are have their
1579 priority adjusted to ensure that they remain at the end of the line.

2206 the end of the line of all holds whose start date falls before
2207 the current system time and that are neither on the hold shelf
2210 The reserve date parameter is optional; if it is supplied, the
2211 priority is based on the set of holds whose start date falls before
2212 the parameter value.

2215 _ShiftPriority. Note that this is currently done in
