 128 =head1 NAME
 129
 130 C4::Circulation - Koha circulation module
 131
 132 =head1 SYNOPSIS
 133
 134 use C4::Circulation;
 135
 136 =head1 DESCRIPTION
 137
 138 The functions in this module deal with circulation, issues, and
 139 returns, as well as general information about the library.
 140 Also deals with stocktaking.
 141
 142 =head1 FUNCTIONS
 143
 144 =head2 barcodedecode
 145
 146   $str = &barcodedecode($barcode, [$filter]);
 147
 148 Generic filter function for barcode string.
 149 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 150 Will do some manipulation of the barcode for systems that deliver a barcode
 151 to circulation.pl that differs from the barcode stored for the item.
 152 For proper functioning of this filter, calling the function on the
 153 correct barcode string (items.barcode) should return an unaltered barcode.
 154
 155 The optional $filter argument is to allow for testing or explicit
 156 behavior that ignores the System Pref.  Valid values are the same as the
 157 System Pref options.

 248
 249 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 250
 251 C<$newbranch> is the code for the branch to which the item should be transferred.
 252
 253 C<$barcode> is the barcode of the item to be transferred.
 254
 255 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 256 Otherwise, if an item is reserved, the transfer fails.
 257
 258 Returns three values:
 259
 260 =over
 261
 262 =item $dotransfer
 263
 264 is true if the transfer was successful.
 265
 266 =item $messages
 267
 268 is a reference-to-hash which may have any of the following keys:
 269
 270 =over
 271
 272 =item C<BadBarcode>
 273
 274 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 275
 276 =item C<IsPermanent>
 277
 278 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.
 279
 280 =item C<DestinationEqualsHolding>
 281
 282 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.
 283
 284 =item C<WasReturned>
 285
 286 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.
 287
 288 =item C<ResFound>
 289
 290 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>.
 291
 292 =item C<WasTransferred>
 293
 294 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1171 AddIssue does the following things :
1172
1173   - step 01: check that there is a borrowernumber & a barcode provided
1174   - check for RENEWAL (book issued & being issued to the same patron)
1175       - renewal YES = Calculate Charge & renew
1176       - renewal NO  =
1177           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
1178           * RESERVE PLACED ?
1179               - fill reserve if reserve to this patron
1180               - cancel reserve or not, otherwise
1181           * TRANSFERT PENDING ?
1182               - complete the transfert
1183           * ISSUE THE BOOK

2258 Internal function, not exported, called only by AddReturn.

2260 FIXME: This function reflects how inscrutable fines logic is.  Fix both.
2261 FIXME: Give a positive return value on success.  It might be the $borrowernumber who received credit, or the amount forgiven.
