=head1 NAME
C4::Reserves - Koha functions for dealing with reservation.
=head1 SYNOPSIS
use C4::Reserves;
=head1 DESCRIPTION
This modules provides somes functions to deal with reservations.
Reserves are stored in reserves table.
The following columns contains important values :
- priority >0 : then the reserve is at 1st stage, and not yet affected to any item.
=0 : then the reserve is being dealed
- found : NULL : means the patron requested the 1st available, and we haven't choosen the item
T(ransit) : the reserve is linked to an item but is in transit to the pickup branch
W(aiting) : the reserve is linked to an item, is at the pickup branch, and is waiting on the hold shelf
F(inished) : the reserve has been completed, and is done
- itemnumber : empty : the reserve is still unaffected to an item
filled: the reserve is attached to an item
The complete workflow is :
==== 1st use case ====
patron request a document, 1st available : P >0, F=NULL, I=NULL
a library having it run "transfertodo", and clic on the list
if there is no transfer to do, the reserve waiting
patron can pick it up P =0, F=W, I=filled
if there is a transfer to do, write in branchtransfer P =0, F=T, I=filled
The pickup library recieve the book, it check in P =0, F=W, I=filled
The patron borrow the book P =0, F=F, I=filled
==== 2nd use case ====
patron requests a document, a given item,
If pickup is holding branch P =0, F=W, I=filled
If transfer needed, write in branchtransfer P =0, F=T, I=filled
The pickup library receive the book, it checks it in P =0, F=W, I=filled
The patron borrow the book P =0, F=F, I=filled

This function gets the list of reservations for one C<$biblionumber>,
returning an arrayref pointing to the reserves for C<$biblionumber>.
By default, only reserves whose start date falls before the current
time are returned. To return all reserves, including future ones,
the C<all_dates> parameter can be included and set to a true value.
If the C<itemnumber> parameter is supplied, reserves must be targeted
to that item or not targeted to any item at all; otherwise, they
are excluded from the list.

Find a book in the reserves.
C<$itemnumber> is the book's item number.
C<$lookahead> is the number of days to look in advance for future reserves.
As I understand it, C<&CheckReserves> looks for the given item in the
reserves. If it is found, that's a match, and C<$status> is set to
C<Waiting>.
Otherwise, it finds the most important item in the reserves with the
same biblio number as this book (I'm not clear on this) and returns it

Change a hold request's priority or cancel it.
C<$rank> specifies the effect of the change. If C<$rank>
is 'W' or 'n', nothing happens. This corresponds to leaving a
request alone when changing its priority in the holds queue
for a bib.
If C<$rank> is 'del', the hold request is cancelled.
If C<$rank> is an integer greater than zero, the priority of
the request is set to that value. Since priority != 0 means
that the item is not waiting on the hold shelf, setting the
priority to a non-zero value also sets the request's found
status and waiting date to NULL.
The optional C<$itemnumber> parameter is used only when
C<$rank> is a non-zero integer; if supplied, the itemnumber
of the hold request is set accordingly; if omitted, the itemnumber
is cleared.
B<FIXME:> Note that the forgoing can have the effect of causing
item-level hold requests to turn into title-level requests. This
will be fixed once reserves has separate columns for requested
itemnumber and supplying itemnumber.

on the same bib.
In the first form, where a reserve_id is passed, the priority of the
hold is set to supplied rank, and other holds for that bib are adjusted
accordingly. If the rank is "del", the hold is cancelled. If no rank
is supplied, all of the holds on that bib have their priority adjusted
as if the second form had been used.
In the second form, where a biblionumber is passed, the holds on that
bib (that are not captured) are sorted in order of increasing priority,
then have reserves.priority set so that the first non-captured hold
has its priority set to 1, the second non-captured hold has its priority
set to 2, and so forth.
In both cases, holds that have the lowestPriority flag on are have their
priority adjusted to ensure that they remain at the end of the line.
Note that the ignoreSetLowestRank parameter is meant to be used only

This increments the priority of all reserves after the one
with either the lowest date after C<$reservedate>
or the lowest priority after C<$priority>.
It effectively makes room for a new reserve to be inserted with a certain
priority, which is returned.
This is most useful when the reservedate can be set by the user. It allows
the new reserve to be placed before other reserves that have a later
reservedate. Since priority also is set by the form in reserves/request.pl
the sub accounts for that too.
