=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
W(aiting) : the reserve has an itemnumber affected, and is on the way
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=NULL, 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=NULL, I=filled
The pickup library recieve the book, it checks it in P =0, F=W, I=filled
The patron borrow the book P =0, F=F, I=filled

As I understand it, C<&CheckReserves> looks for the given item in the
reserves. If it is found, that's a match, and C<$status> is set to
C<Waiting>.
Otherwise, it finds the most important item in the reserves with the
same biblio number as this book (I'm not clear on this) and returns it
with C<$status> set to C<Reserved>.
C<&CheckReserves> returns a three-element list:
C<$status> is either C<Waiting>, C<Reserved> (see above), or 0.
C<$reserve> is the reserve item that matched. It is a
reference-to-hash whose keys are mostly the fields of the reserves
table in the Koha database.
C<$count> is the number of reserves for this item.

=back
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.
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.

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.
