 104 =head1 NAME
 105
 106 C4::Circulation - Koha circulation module
 107
 108 =head1 SYNOPSIS
 109
 110 use C4::Circulation;
 111
 112 =head1 DESCRIPTION
 113
 114 The functions in this module deal with circulation, issues, and
 115 returns, as well as general information about the library.
 116 Also deals with stocktaking.
 117
 118 =head1 FUNCTIONS
 119
 120 =head2 barcodedecode
 121
 122   $str = &barcodedecode($barcode, [$filter]);
 123
 124 Generic filter function for barcode string.
 125 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 126 Will do some manipulation of the barcode for systems that deliver a barcode
 127 to circulation.pl that differs from the barcode stored for the item.
 128 For proper functioning of this filter, calling the function on the
 129 correct barcode string (items.barcode) should return an unaltered barcode.
 130
 131 The optional $filter argument is to allow for testing or explicit
 132 behavior that ignores the System Pref.  Valid values are the same as the
 133 System Pref options.

 181 or Javascript based decoding on the client side.

 216
 217 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 218
 219 C<$newbranch> is the code for the branch to which the item should be transferred.
 220
 221 C<$barcode> is the barcode of the item to be transferred.
 222
 223 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 224 Otherwise, if an item is reserved, the transfer fails.
 225
 226 Returns three values:
 227
 228 =over
 229
 230 =item $dotransfer
 231
 232 is true if the transfer was successful.
 233
 234 =item $messages
 235
 236 is a reference-to-hash which may have any of the following keys:
 237
 238 =over
 239
 240 =item C<BadBarcode>
 241
 242 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 243
 244 =item C<IsPermanent>
 245
 246 The item's home branch is permanent. This doesn't prevent the item from being transferred, though. The value is the code of the item's home branch.
 247
 248 =item C<DestinationEqualsHolding>
 249
 250 The item is already at the branch to which it is being transferred. The transfer is nonetheless considered to have failed. The value should be ignored.
 251
 252 =item C<WasReturned>
 253
 254 The item was on loan, and C<&transferbook> automatically returned it before transferring it. The value is the borrower number of the patron who had the item.
 255
 256 =item C<ResFound>
 257
 258 The item was reserved. The value is a reference-to-hash whose keys are fields from the reserves table of the Koha database, and C<biblioitemnumber>. It also has the key C<ResFound>, whose value is either C<Waiting> or C<Reserved>.
 259
 260 =item C<WasTransferred>
 261
 262 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

 911
 912 =item C<$borrower> is a hash with borrower informations (from GetMemberDetails).
 913
 914 =item C<$barcode> is the barcode of the item being issued.
 915
 916 =item C<$datedue> is a C4::Dates object for the max date of return, i.e. the date due (optional).
 917 Calculated if empty.
 918
 919 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
 920

 924 AddIssue does the following things :
 925
 926   - step 01: check that there is a borrowernumber & a barcode provided
 927   - check for RENEWAL (book issued & being issued to the same patron)
 928       - renewal YES = Calculate Charge & renew
 929       - renewal NO  =
 930           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
 931           * RESERVE PLACED ?
 932               - fill reserve if reserve to this patron
 933               - cancel reserve or not, otherwise
 934           * TRANSFERT PENDING ?
 935               - complete the transfert
