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

 250
 251 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 252
 253 C<$newbranch> is the code for the branch to which the item should be transferred.
 254
 255 C<$barcode> is the barcode of the item to be transferred.
 256
 257 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 258 Otherwise, if an item is reserved, the transfer fails.
 259
 260 Returns three values:
 261
 262 =over
 263
 264 =item $dotransfer
 265
 266 is true if the transfer was successful.
 267
 268 =item $messages
 269
 270 is a reference-to-hash which may have any of the following keys:
 271
 272 =over
 273
 274 =item C<BadBarcode>
 275
 276 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 277
 278 =item C<IsPermanent>
 279
 280 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.
 281
 282 =item C<DestinationEqualsHolding>
 283
 284 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.
 285
 286 =item C<WasReturned>
 287
 288 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.
 289
 290 =item C<ResFound>
 291
 292 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>.
 293
 294 =item C<WasTransferred>
 295
 296 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1233
1234 Issue a book. Does no check, they are done in CanBookBeIssued. If we reach this sub, it means the user confirmed if needed.
1235
1236 =over 4
1237
1238 =item C<$borrower> is a hash with borrower informations (from GetMember).
1239
1240 =item C<$barcode> is the barcode of the item being issued.
1241
1242 =item C<$datedue> is a DateTime object for the max date of return, i.e. the date due (optional).
1243 Calculated if empty.
1244
1245 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
1246
1247 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
1248 Defaults to today.  Unlike C<$datedue>, NOT a DateTime object, unfortunately.
1249
1250 AddIssue does the following things :
1251
1252   - step 01: check that there is a borrowernumber & a barcode provided
1253   - check for RENEWAL (book issued & being issued to the same patron)
1254       - renewal YES = Calculate Charge & renew
1255       - renewal NO  =
1256           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
1257           * RESERVE PLACED ?
1258               - fill reserve if reserve to this patron
1259               - cancel reserve or not, otherwise
1260           * TRANSFERT PENDING ?
1261               - complete the transfert
1262           * ISSUE THE BOOK

2591 Find out whether a borrowed item may be renewed.
2592
2593 C<$borrowernumber> is the borrower number of the patron who currently
2594 has the item on loan.
2595
2596 C<$itemnumber> is the number of the item to renew.
2597
2598 C<$override_limit>, if supplied with a true value, causes
2599 the limit on the number of times that the loan can be renewed
2600 (as controlled by the item type) to be ignored. Overriding also allows
2601 to renew sooner than "No renewal before" and to manually renew loans
2602 that are automatically renewed.
2603
2604 C<$CanBookBeRenewed> returns a true value if the item may be renewed. The
2605 item must currently be on loan to the specified borrower; renewals
2606 must be allowed for the item's type; and the borrower must not have
2607 already renewed the loan. $error will contain the reason the renewal can not proceed
